Title: Electrically heatable windshield with a hidden bus bar
IPC: H05B3/26
Filed: 1989-10-26
Abstract: An electrically heatable windshield with a hidden bus bar configuration.  A border of opaque ceramic material is bonded to an interior surface of the transparency about its periphery.  Opposing electroconductive bus bars are bonded to the ceramic material so that the entire inner edge of the bus bar overlays a portion of the ceramic material and is spaced from the inner edge of the border, providing an intermediate portion of the border between the bus bars and transparency surface that is not covered by the bus bars.  An electroconductive coating is applied to the transparency to interconnect the bus bars and and covers to the inner surface of the transparency, the bus bars and the intermediate portion of the ceramic material border so that electric current flowing between the bus bars must flow through the portion of the coating that covers the intermediate portion of the border.
Patent CA-2003799-A1 (CA)
Inventor: SHELLENBERGER TIMOTHY J
IPC: F23N5/18
Filed: 1989-11-24
Abstract: ABSTRACT         In an induced draft, fuel-fired furnace a flow restric-tion in the external exhaust flue is detected, and the furnace burners responsively deactivated,  by a thermal  sensing switch mounted in a spaced relationship with a small flow opening formed in a sensor housing externally secured to the inducer fan outlet section over a wall opening therein.  During normal burner com-bustion product discharge flow through the exhaust flue, a small vane within the  inducer  fan outlet  section creates a venturi therein which draws ambient air within the furnace housing across the temperature sensing switch and into the fan outlet section through the sensor housing opening.   The temperature of this ambient  air  is below the  switch  set point  so that continued burner operation  is permitted.   However,  if the exhaust flue becomes restricted or  blocked the resulting pressure increase within  the  inducer  fan  outlet  section  overcomes  the  venturi effect therein and forces hot burner combustion products out-wardly through  the  sensor  housing and across  the temperature sensing switch.  When the temperature of the switch reaches its set point, the switch operates to deactivate the furnace burners.
Patent CA-2005863-A1 (CA)
IPC: H04J3/06
Filed: 1989-12-18
Abstract: The bit phase difference recognizing unit is provided within a master apparatus and recognizes a bit phase difference of respective data corresponding to respective slave apparatuses.   A bit phase difference correcting unit provided within the master apparatus corrects the bit phase difference of respective data  in processing respective data corresponding to respective slave apparatuses,   based on the recognition result obtained by the bit phase difference recognizing unit.  For example, when a master apparatus of an electronic exchange apparatus performs an exchange connection process, the bit phase difference is directly corrected. Therefore, a special buffer for correcting the bit phase difference is not necessary and the present invention can be flexibly adapted for the case where the bit phase difference changes.

Abstract: A vertical storage unit is provided for modular furniture of the type having a worksurface with an open knee space below the worksurface.  The storage unit includes an open framework drawer, which is slidably mounted in a hollow cabinet for horizontal movement between a closed position in which the sides of the drawer are disposed in the cabinet, and an open position in which the sides of the drawer are disposed outside of the cabinet, and extend perpendicular beyond the worksurface.  A plurality of removable, drop-in storage trays are suspended from the drawer framework in a vertically spaced apart relationship. The sides of the drawer are open to access each storage tray, such that when the drawer is in the open position, objects may be placed into and removed from the vertically arranged storage trays with a generally vertical hand motion.  Convenient storage is thereby provided within arm's length of the worksurface, without encroaching upon the knee space below the worksurface, so as to provide improved freedom of movement, particularly in task environments.

Patent CA-2019787-A1 (CA)
IPC: G06F9/45
Filed: 1990-06-26
Abstract: A computer program is optimized prior to carrying out the final  compilation.   Subgraphs  within  the  program  are identified and examined for optimization beginning with the entire  program  as  the  largest  subgraph.  The  number  of entities  in  each  subgraph  which  are  relevant  to  each dimension of arrays used to represent data flow equations is determined. Next, the amount of memory required to contain the  arrays  is determined.  If that memory requirement is within a predefined memory usage limit for the compilation, then a specified procedure of the compilation process is applied.  If the memory requirement to contain the arrays exceeds  the  predefined  memory  usage   limit  for  the compilation,  the  process  is  repeated  for  successively smaller subgraphs within the program in an attempt to find a subgraph to which the memory limits allow application of the specified procedure.

Title: Natural gas feeding process of catalytic burner and corresponding device
Inventor: JAVET ALAIN
IPC: F23D14/66
Filed: 1990-06-25
Abstract: The distribution-pressurized natural gas is supplied via a conduit (C1) arranged in the piston (P) of an electrovalve (EV) in a nozzle (BG) of which the outlet leads to a cone (C) which provides, with the nozzle (BG), a ring-shaped opening (BA) which, connected to the atmosphere, acts as a secondary nozzle for injecting air into the gas flow. The cone (C) is followed by a cylindrical element (S1) then by an abrupt widening (BC) section (S2) which opens into a heat exchanger (EC) which is in contact with a substrate impregnated with a catalytic material (MC) which oxidizes fuel gas. A small amount of air is sucked up by the widening (BC) and mixed with the gas. This mixture is then treated in the exchanger (EC) up to the transformation temperature of the sulphur-containing compound and the sulphur is then oxidized.
