Patent CA-2135748-A1 (CA)
Title: Methods and agents for modulating immune response, and uses thereof
Inventor: CERAMI ANTHONY
IPC: C07K19/00
Filed: 1993-05-17
Abstract: A method of enhancing antigen presentation is disclosed, wherein an antigen is modified by reaction with AGEs or a compound which forms AGEs. The AGEs are formed on or attached to the antigen, at a site which either activates an epitope containing the site of AGE attachment or formation, or which activates a different site in the antigen, a so-called "silent" epitope. This may comprise an actual activation process, a shift in the dominance to a different epitope by reducing recognition of the epitope upon which the AGEs are found or another mechanism. Also included are the antibodies which recognize these epitopes, methods of treatment and use, assay techniques and kits for performing such methods.

Patent CA-2139969-A1 (CA)
Title: Throttle position validation method and apparatus
Inventor: HARDIN GEORGE T
IPC: F02D45/00
Filed: 1995-01-11
Abstract: An engine control system is disclosed having a unit for providing signals indicative of the position of an engine throttle member. The unit comprises a housing assembly associated with an engine throttle member and containing a stator assembly and a rotor assembly. The rotor assembly moves relative to the stator assembly as the throttle member moves. The rotor and stator assemblies are electrically coupled together for producing first and second continuously variable, ratiometrically identical signals whose values depend upon the throttle member position. The first signal is delivered from the housing assembly for use in controlling the engine operation. Processing circuitry processes the second signal for producing a throttle' position validation signal having a first value when the throttle member is in an engine idle range of positions and a second value when the throttle member moves beyond the idle range of positions. If the first signal and the validation signal signify incompatible throttle member positions the engine speed is limited to "idle."

Patent CA-2147203-A1 (CA)
Inventor: MUELLER HERBERT RICHARD
IPC: F24D5/12
Filed: 1995-04-18
Abstract: The invention described herein pertains to an air-conditioning unit contained in a single and compact enclosure, the same unit being able to carry out the functions of a heat pump, a de-humidifier, and an air exchanger with energy recovery capability.     The unit is comprised of a compressor, two heat exchangers (either one of which has to function as both condenser or evaporator), a refrigerant flow change-over valve, one air flow change-over valve, one outdoor air shut-off mechanism integrated with a second air change-over valve, and two fan assemblies.     By positioning a center-pivoting air valve as a separation between the two heat exchangers, and placing the three items transversely to the length of the unit, indoor air can be selectively drawn across either one of the heat exchangers, while at the same time outside air is drawn across the other heat exchanger. This construction allows the unit to function as a heat pump or as a fresh air exchanger with energy recovery capability, depending on the positioning of the air valve. A refrigerant flow change-over valve will select which task (condensing or evaporating) each of the heat exchangers has to carry out. By closing off access to the outside with an additional shutter type shut-off mechanism, the air flow through the unit is routed to the central inside section of the cabinet and the de-humidifying mode is established. Thus the modes of heating, cooling, air exchange with heating or cooling capability (energy recovery), and de-humidifying can be obtained with this type of apparatus.     The appliance can be produced as a compact unit with the smaller capacity sizes capable of being installed in either a window or wall opening, while the larger capacity units can be positioned either outdoors or in a basement and ducted to a standard duct system.

Title: Selective calling system and selective calling receiver
Inventor: MINAMI YOICHIRO
IPC: H04W88/02
Filed: 1995-07-13
Abstract: A transmission signal frame format comprises an address field and a message field.  The address field comprises a plurality of addresses associated with the subscriber's receivers to be called, respectively.  The message field comprises a plurality of messages corresponding to the addresses, respectively.  A message includes a transmitting sequence number which is coincident with the transmitting order of the address corre-sponding to this message.

Patent CA-2157826-A1 (CA)
Title: Air separation method and apparatus
Inventor: MOSTELLO ROBERT A
IPC: F25J3/04
Filed: 1995-09-08
Abstract: An air separation method and apparatus in which air is separated by a low temperature rectification process having cooling and rectification stages for cooling air to a temperature suitable for its rectification and for distilling or fractionating the air into fractions enriched in components of the air, respectively. A process stream flowing between the cooling and distillation stages is either partially warmed or cooled and is then expanded in a turboexpander to produce a refrigerant stream. The refrigeration is recovered within the cooling stage and after the refrigerant stream has fully warmed, the refrigerant stream is drawn at subatmospheric pressure by a blower or the like and is then discharged at or above atmospheric pressure. The drawing of the air at subatmospheric pressure increases the turboexpander pressure ratio to in turn increase the amount of refrigeration that is supplied.
