\ctrline {\lv Special Characters and Figures in \TEX\ Prepared Documents}

{\sl Problem\/}: To produce a \TEX\ generated {\ei PRESS} file for the
{\ei DOVER}, using standard fonts and some additional (locally generated)
characters, fonts or sketches that are not in the {\ei IFS} font
dictionary. The purpose would be to permit the user to add special
({\ei METAFONT}) characters and high-quality illustrations to a \TEX\
prepared document and to experiment with special fonts, all without the
hassle and inconvenience to others that is involved in adding material to
the {\ei IFS} dictionary.

This problem may already have been considered and a solution may even be
at hand but it may still be worth while to outline my current ideas.

One way to handle the problem would be to modify the {\ei IFS} - {\ei
DOVER} complex so that fonts need not all be on one dictionary and so that
each user could have an additional private dictionary of characters, fonts
and figures that his {\ei PRESS} files could use. This would involve
delving into the inners of {\ei IFS} and, presumably, should only be done
in cooperation with Xerox.  They might or might not favor the idea.  \TEX\
would have to be modified so that it could specify and reference two
different font dictionaries.

At the other extreme, one could modify \TEX\ so that it could take care of
the entire job.  The locally created fonts would be left on SUAI and when
characters were to be used from these fonts they would be added to the
{\ei PRESS} file (presumably, in raster form). This could lead to the
creation of very large {\ei PRESS} files.

Still another possibility would be to devise an in-between solution.

One such solution would be to have a \TEX\ Preprocessor that would search
out and extract all local-font references in a \TEX\ source file, compute
their space requirements (using locally stored width tables) and generate
a new \TEX\ input file with these extractions replaced by properly-sized
empty (or numbered) boxes.  At the same time this preprocessor would
create a second file containing the extracted information relating to the
local-font characters that are to go in these boxes.  \TEX\ could then be
used in the normal way to produce a properly-formatted preliminary {\ei PRESS}
file with empty spaces reserved for the missing material.

Alternately, one might modify \TEX\ so that it could do all of this. In
fact, it might be possible to do the whole task by using macros.  Macros
would, of course, be used to prepare the supplementary output file that
tells what the boxes are to contain, in much the same way that tables of
contents and indexes are now handled.

The output from the Preprocessor or the supplementary output from \TEX\
would then have to be proccessed into {\ei PRESS} format and finally a
PressEdit type of program would be used to merge the two {\ei PRESS} files
into a file for printing by the {\ei DOVER}.  The supplementary {\ei
PRESS} files, so created, would probably be rather large but these files
could be deleted automatically as soon as used since they could always be
recreated when needed.

As for the drawing problem, {\ei METAFONT} can be used directly for small
sketches (up to roughly 1 3/8 inches on a side) and larger figures can be
created in sections.  One might, however, like to have a separate drawing
program, perhaps one that did not have all of the niceties of {\ei
METAFONT}, but one that could handle larger areas directly.

	The Case for Solar Heating\cr
	at\cr
	The Sequoias, Portola Valley\cr}

A good case can be made for the desirability of installing a solar heating
system at The Sequoias.  We would like to do what we can to help meet the
energy crunch, we are faced with an ever rising cost of fuel, and we have
a population of elderly people that cannot easily tolerate the lowering of
room temperatures that might otherwise be imposed.  In spite of the
long-range desirability of solar heating, it has still been hard to
justify the installation costs on purely economic grounds, but the
situation is changing.  The social pressure for solar conversions has
somewhat abated, market forces are coming into play and the cost of the
necessary equipment is either coming down or at least not going up as fast
as inflation.  Now could be the opportune time to install solar heating.

Our situation at The Sequoias is also rather unusual.  We have a
substantial number of scattered single-story buildings with large roof
areas, that can be used to mount the solar panels, and we have a central
heating system with all of the necessary piping to distribute heated water
to, and to collect heated water from, these scattered buildings.

The basic scheme would be: 1) to construct a large centrally-located water
storage tank, 2) to install solar panels on the roofs of the individual
buildings and 3) to connect these panels to the heating system through
the already existing plumbing in the individual buildings.  During sunny
daylight hours, the net flow of heat would be from the outlying buildings
to the central storage tank.  The availability of this stored hot water
would reduce the demands placed on the existing gas-fired system and
greatly reduce our expenses for fuel.

There are a number of problems that will have to be faced.

Objections are sure to be raised to the appearance of
the solar panels.  This aspect of solar heating is receiving considerable
attention and the newer panel designs are much better looking than were
the earlier ones.  Also, there is the gradual acceptance of the need for
solar heating and the panels are coming to be accepted as a necessary part
of any modern building.  Consideration will have to be given to the
adequateness of the roof structure to support the added weight and the
possible need for additional bracing, but this is not apt to be a serious
problem.

We do have a problem in that most of our buildings are at an angle to the
cardinal directions and the roof pitch is less than optimum for the
installation of solar panels.  The panels could, of course, be raised from
the roof surfaces so as to face more nearly in the optimum direction, but
this would be unsightly and hardly worth the cost.  Having some panels facing
south-east and others facing south-west will lengthen the total number of
hours that some panels will be effective, but at a cost in terms of
overall efficiency.

Another major problem will be the location of the hot-water storage tank.
Common sense dictates that the tank be underground and as near to the Main
Building as possible.  A desirable location, meeting these requirements,
might be under Fountain Court.  We would have to look into the subsurface
conditions, but is unlikely that rock would be encountered.  The most
serious objection to this location would be the inconvenience that
residents would experience during the construction work.  Fountain Court
could be restored to its present condition or perhaps improved on the
completion of the project.  An alternate location for the tank might be in
the area near the bowling green but this would require rather long piping
with the attendant heat losses.  All things considered, the Fountain Court
location seems the best.

Fortunately, no additional piping between buildings should be required.
Hot water is now being piped from the Main building to the outlying
buildings and the only change would be that during daylight hours the
temperature of the return water would be higher than the temperature of
the outgoing water.  Additional water pumps in the individual utility
rooms will probably be needed to control the circulation of water to the
solar panels.

The final consideration is, of course, that of cost in relationship to
the potential saving.  Solar panels come in a variety of types, some are
relatively cheap in terms of initial cost but are rather unreliable and could
involve a great deal of maintenance costs while the better designs are
still rather expensive.  Because of the size of our job, we should be able
to get fairly favorable terms.

The second major cost will be that of constructing the necessary storage
tank.  If the tank is too small, the amount of heat that can be
stored (subject to reasonable temperature constraints) will not be
adequate to compensate for the cost of the entire system.  Constructing
the tank should be a one time job and so it would be well to make it big
enough.  By way of contrast, we might limit the number of solar panels
that we install initially, both to save on the initial cost and in the
hopes that the panels will become cheaper and better in design with time.

In summary, it seems that a reasonable solar heating system could be be
constructed at The Sequoias, Portola Valley and that there are many reasons 
why such a project should be undertaken at this time.  There does remain
the problem of financing.  This is a bad time to borrow money but perhaps
someone might be induced to make a contribution to The Sequoias toward
partially underwriting the project.
