Title: Data processing terminal with addressable  characterising store
Inventor: HIRSCHMAN JOEL A
IPC: G09G5/00
Filed: 1979-09-27
Granted: 1982-04-27
Abstract: ABSTRACT (Figure 1 refers) A  data  processing terminal incorporates a microprocessor (1) to which various input/output devices such as a  communi-cations  adapter (5), and a keyboard (7) are connected.  A set up store (9)  containing  terminal  characterisation  data,  a read  only  store  (10)  containing  microcode,  and  a random access  memory  (11)  for  containing microcode,  data,   and characters  to  be  displayed  on  a cathode ray tube 517) are also connected to the data and address busses  (2  and  3)  of the  microprocessor.   Refresh control (18) refreshes the CRT. The terminal feature  characterisation  data  in  the  set  up store  (9)  can  be  changed from the keyboard when additional features  are  installed  or  when  the  terminal   is   first installed.    Various   sequences  which  are  used  when  the terminal is in ALTER  mode are described.  The  set  up  store (9)  can suitably be formed from a battery-powered CMOS random access memory which will retain data stored therein  when  the power  to the terminal is off.  This allows the microprocessor or  operator  to  reconfigure  the  terminal  when  power   is switched on.

Abstract: Abstract of the Disclosure An apparatus for providing a high, positive locking force at the bottom of a nuclear fuel assembly to resist upward coolant flow forces.  A latch on the fuel assembly alignment post is cammed to engage the fuel alignment pin in the core support stand and is linked to an actuating rod extending through the lower end of the fuel assembly center guide tube.  The upward flow of coolant against the link and actuating rod causes the link to approach the horizontal, thereby exerting a high locking force between the latch and the fuel alignment pin.  In the preferred embodiment spring means interact between the lower end fitting and the actuating rod to maintain an upward bias on the rod.

Abstract: CLOSED HEAT PUMP SYSTEM PRODUCING ELECTRICAL POWER     ABSTRACT      A method of electrical power generation is disclosed wherein the energy source to operate the said electrical power generation apparatus is that energy existing between two fluid sources being at different temperatures and therefore at different energy levels.  These fluid sources could be as divergent as warm underground crude oil as it is pumped  from wells and the cooler atmospheric air above the said oil wells, or as intimately related as the warm water output from conventional and nuclear power generating plants and the cooling water source usually available to such generating plants.  Warm water pumped from deep below the earth's surface, geo-thermally heated, as the warm or hot source and surface water from lakes, oceans, rivers, etc. as the colder, or lower energy source provides an additional source of energy for the method of electrical power gener-ation herein described.  Perhaps the largest source of waters, in which sufficient temperature differentials exist, are tropical ocean waters where temperature differences between the warm surface water and the cold deep ocean water, several thousand feet below the ocean surface, are often as high as 40° to 45° F.
