Patent CA-2135259-A1 (CA)
Inventor: CHESNOY JOSE
IPC: H04B10/2531
Filed: 1994-11-07
Abstract: Procédé de télécommunication à fibres optiques, liaison appliquant ce procédé et système de pompage pour mélange à quatre ondes notamment pour cette liaison Des ondes optiques (W1, W2) portant un signal à transmettre (S) sont guidées dans une ligne constituée de fibres optiques présentant une dispersion chromatique. Pour compenser des effets de cette dispersion on provoque en un point intermédiaire de la ligne un phénomène de mélange à quatre ondes à l'aide d'une lumière de pompage injectée dans une fibre de mélange (8). Selon l'invention cette lumière de pompage est constituée de deux ondes de pompe (P1, P2). Les polarisations (V1, V2) de ces deux ondes sont orthogonales. Leurs fréquences optiques (?P1, ?P2) sont sensiblement symétriques l'une de l'autre par rapport à une fréquence neutre (?o) annulant la dispersion chromatique de cette fibre de mélange. L'invention s'applique notamment aux liaisons de grandes longueurs. Figure à publier : Fig. 1

Inventor: PALMER ROGER KEITH
IPC: A22C17/00
Filed: 1993-06-11
Abstract: A method and apparatus for the treatment and/or storage of meat; the apparatus includes a method of containing a plurality of meat portions in a contiguous body and subjecting the body of meat to compression in a controlled gas flushed environment. The method includes the step of substantially protecting a large area of the surface of the meat from direct contact with the gas flushed environment where vacuum and the presence of gases occur. The meat is held in the controlled environment at low temperatures to enable an ageing process to occur. The method and apparatus also facilitates simultaneous storage and ageing of the meat under controlled conditions during transportation.

Title: Dragline excavator bucket and rigging
Inventor: SCHMIDT DON F
IPC: E02F3/60
Filed: 1993-08-17
Abstract: A dragline excavating bucket (110) is constructed to be supported through a minimum number of support chains and control cables, and made to provide for rapid digging and distribution of overburden removed by dumping the bucket rearwardly over a rear wall of the bucket. The bucket is supported on hoist chains (156) that are located forwardly of the center of gravity so the bucket tends to tip rearwardly. The tilted portion of the bucket is controlled through a pair of drag chains (134) that not only provide the pull force for loading the bucket, but also control the dumping of material from the bucket over the rear wall (114). Sliding trunnions (159) are used on the bucket pivots to enhance dumping operation.

Title: Cooling system for a post-mix beverage dispenser
Inventor: MILLS JEFFREY P
IPC: G07F13/06
Filed: 1995-03-29
Abstract: A cooling system for post-mix beverage dispenser includes an ice bath tank for holding a liquid, a refrigeration circuit for cooling the liquid in the ice bath tank, a concentrate storage area, and a cooling circuit coupled to the ice bath tank, for cooling the concentrate storage area. A pump in the cooling circuit transfers the liquid from the ice bath tank to a coil in the concentrate storage container.  The circuit returns the liquid to the ice bath tank and creates the turbulence necessary for the liquid to freeze evenly in the tank.  Thus, an agitator assembly is not necessary.  A fan in the concentrate storage area circulates air over the coil.  The pump can be selectively coupled to drain the tank.
Patent CA-2150959-A1 (CA)
Inventor: NEBLETT IAN GLENN
IPC: F04C29/12
Filed: 1995-06-05
Abstract: A system having a matched vane compressor and impeller is described for use in either a hydraulic system or in a two phase air conditioning system.     The impeller is matched to the compressor to return work to the compressor through a shaft or gearbox. The compressor is a vane compressor having longitudinally reciprocating vanes carried in a slotted disc between matched, opposed cam faces forming a series of variable geometry chambers which draw in and expel working fluid during rotation of the shaft. Compression is achieved by exposing the fluid in the chambers to high pressure fluid while the volume of the chamber is not changing. A pressurizing port is placed tangentially to the chambers for this purpose. The impeller also makes use of tangentially disposed pressure ports to expose the turning pockets of a drum to higher pressure. The outlet of the impeller only skims off a surface layer of the liquid in the pockets, reducing the volumetric through flow of the impeller while it returns work to the compressor. These systems can be utilized in hydraulic or thermal applications.

Patent CA-2155221-A1 (CA)
Inventor: KRISSTTOVVV
IPC: A01K61/00
Filed: 1995-07-25
Abstract: The most important feature of this process is that no water is dumped as in existing fish raising facilities and the operator completely controls the water quality. All the water  is continually recirculated and is continually sterilized by  the use of OZONE gas in the O3 state. The OZONE gas in the water that is left over is then changed back to oxygen by the use of ultraviolet rays in the 254 nanometer range and is pumped into the water tank containing the aquatic life. By changing the OZONE back to oxygen the need for large air pumps is eliminated, thus stopping the harmful practice of pumping 78% nitrogen into the water.    Twice as many fish, for example, can be raised one and one half times quicker with no dumping of fish wastes and with one half the utility bill. Fish health is controllable as well.

Title: Immunologic enhancement with intermittent interleukin-2 therapy
Inventor: LANE H CLIFFORD
IPC: A61K38/20
Filed: 1994-05-19
Abstract: A method for activating a mammalian immune system entails a series of continuous IL-2 infusions that are effected intermittently over an extended period. For exemple, IL-2 can be administered continuously for a period that is on the order of 5 days in length, and successive infusions of this nature can be separated by a period of at least 4 weeks. Sustained beneficial effects, including elevated CD4 cell counts, restoration of lymphocyte function and an increase in the number of IL-2 receptors, are achieved with such intermittent IL-2 therapy, which can be combined with another therapy which targets a specific disease state, such as an anti-retroviral therapy comprising, for example, the administration of AZT, ddI or interferon alpha. In addition, IL-2 administration can be employed to facilitate in situ transduction of T cells in the context of gene therapy. By this approach the cells are first activated in vivo via the aforementioned IL-2 therapy, and transduction then is effected by delivering a genetically engineered retroviral vector directly to the patient.

Title: System and method for collision warning based on dynamic deceleration capability using predicted road load
Inventor: CHAKRABORTY SHUBHAYU
IPC: B60W30/16
Filed: 1996-02-28
Abstract: A system and method for collision warning utilize a sensor  (58)  to determine an inter-vehicle distance  and/or closing rate relative  to a  forward vehicle.  A predicted vehicle road load is determined using a predetermined number of previous  road load values which is then utilized to determine whether the vehicle has sufficient deceleration capability so as to avoid a collision without operator intervention.   The vehicle  road load accounts  for various  forces both internal  and  external  to  the  vehicle  which  resist forward motion  including  those  due  to  gravity  and aerodynamic  drag,  and  those provided  by  an  engine retarder or downshifting of an automatic transmission. The present invention thus avoids spurious collision indications.

Filed: 1994-11-03
Abstract: In order to extend the useful life of electrical storage battery cells under float voltage charge it is advisable to maintain the polarization of the positive plates (22) of the cell relative to a reference electrode (26) in the cell at a predetermined level. This invention provides a sensing and controller circuit (20) which drains minute amounts of current from the positive cell plates when the polarization rises above the desired level and thereby prevents plate corrosion and loss of electrolyte. The present invention may be combined with a circuit for increasing cell polarization levels to provide a system for maintaining battery cells at optimum polarization levels over extended float charging periods.
