Title: Electrode for metal halide discharge lamp
Inventor: GRAHAM TIMOTHY W
IPC: H01J61/073
Filed: 1991-12-30
Abstract: A low-wattage metal-halide discharge lamp (10) has a quartz tube (12) of the double ended type hat forms a bulb (14) or envelope, a pair of electrodes, e.g., an anode (30) and a cathode (32), which penetrate in-to an arc chamber (16) inside the envelope(14), and a suitable amount of mercury (98) pies one or more metal halide salts. The electrodes (30, 32) are each formed of a refractory metal, i.e., tungsten wire, extending through the respective necks (22, 24) info the arc chamber (16). The elec-trodes (30, 32) are of a composite design i.e., in the form of a club, with a lead-in wire (34;44) of mall diameter supported in the quartz (12) in the associated neck (22; 24), and a post member (36; 46) of greater di-ameter supported on the lead-in wire (34, 40). The post members (36; 46) are supported out of contact with the quartz of the necks (22, 24) and also out of contact with the bulb wall. The larger size of the post member (36, 46) allows heat at the tip (38, 48) to diffuse back into the post member (36, 46) so that the metal tip (38, 48) will not evaporate.     The narrow lead-in wire (34, 44) keeps most of the heat in the bulb (14) so that flow of heat out of the neck portions (22, 24) is limited. Lamps of this design achieve high efficacy at relative low power (below 40 watts).

Patent CA-2082009-A1 (CA)
Title: Adaptive pressure control for an automatic transmission
Inventor: POLLACK SCOTT B
IPC: F16H61/12
Filed: 1992-11-03
Abstract: An improved adaptive pressure control which accounts for nonlinearity in the relationship between fluid pressure and shift time.  To account for nonlinearity in the relationship between cumulative shift time error and corrective pressure, the control utilizes an empirically derived table of shift time vs. controlled pressure to develop a raw pressure error in lieu of a shift time error.  The adaptive pressure correction, in turn, is developed in relation to the cumulative pressure error.  This removes the effect of system nonlinearity from the adaptive control, allowing more accurate adaptive convergence than was heretofore achieved.

Patent CA-2084253-A1 (CA)
Title: Lighting Control System with Set/Reset Ground Remote
Inventor: ERWIN WILLIAM R
IPC: H05B37/02
Filed: 1992-12-01
Abstract: A lighting load can be turned on/off manually from one or more remote switching stations as well as from a master switch controller station, with ON/OFF control  signals  produced  at  the  remote  switching stations being transmitted to the master controller circuit on the traveler conductor of a conventional single phase AC power distribution system.   The main controller has an internal dual mode DC power supply which is referenced to load potential.  The dual mode power supply derives operating power from the voltage across  the  gate  controlled  power  switch  which corresponds with essentially hot potential when the power switch is off.  The voltage drop across the power switch is boosted by a step-up transformer when the power switch is on.  Remote turn-on and turn-off signals are derived independently from the hot power conductor and ground safety power conductor, respectively.  Remote turn-on and turn-off of the master power switch is accomplished without interfering with automatic turn-off operation of the controller.
Patent CA-2086076-A1 (CA)
Title: Marine Steering Apparatus
Inventor: KOBELT JACOB
IPC: B63H25/22
Filed: 1992-12-22
Abstract: A  fluid  power  apparatus  is  connected  to  a pressurized fluid supply and a conventional helm pump controlled by the helm of a vessel to shift the rudder. The apparatus comprises an actuator cylinder connectable to the rudder, and a servo cylinder and a main valve connected to the helm pump to pass fluid therebetween and between the actuator  cylinder.    The  actuator  cylinder  and  servo cylinder  have  respective  bodies  and  piston  rods,  and portions of the servo cylinder and actuator cylinder are connected together for concurrent simultaneous movement along  respective  longitudinal  axes.    Valve  shifting structure is responsive to a change in fluid signal from the helm pump applied to the servo apparatus.   Fluid diverting structure is responsive to a threshold supply pressure so as to actuate the valve to stop flow of supply fluid when  supply  pressure  drops  below  the  threshold pressure.  When pressurized fluid is available, the valve is actuated in response to a fluid signal from the helm pump and the actuator cylinder receives pressurized fluid from the valve and directs fluid back to the valve.  When pressurized fluid is not available, the valve is actuated in response to a fluid signal from the helm pump and the valve is effectively by-passed and the actuator cylinder receives  fluid from the helm pump and is actuated by manually applied pressures.

Title: Remediation of low level radioactive mixed waste in a fluidized bed incinerator
Inventor: WARCHOL JAMES J
IPC: F23G5/30
Filed: 1993-11-01
Abstract: ABSTRACT OF THE DISCLOSURE Mixed waste containing organic constituents and low  level  radioactive  waste  is  remediated  in  a circulating fluidized bed combustor.  Three separators are used to filter the flue gas and separate fine radioactive  material  from  coarse  non-radioactive material thereby concentrating the radioactive portion. A primary separator separates large  material such as sand, lime, flyash or unburned fuel particles from the flue gas leaving the furnace of the combustor.  The flue gas is then passed to a secondary separator for the collection of finer particles.  In turn, the flue gas is passed to a tertiary separator for the collection of the finest particles of the flue gas containing low level radioactive waste.   Solids entrained in the primary separator  are  recycled  back  into  the  bed  of  the combustor through an L-valve.  Solids entrained at the secondary separator are also recycled back into the bed.
