Title: Contact retention arrangement for high density cable connector assembly
Inventor: LAPRAIK SCOTT J
IPC: H01R13/04
Filed: 1993-05-06
Abstract: CONTACT RETENTION ARRANGEMENT FOR HIGH DENSITY CABLE CONNECTOR ASSEMBLY          ABSTRACT OF THE DISCLOSURE:          A high density electrical connector is provided for  supporting  a plurality  of contact  assemblies  in a geometric  array.    Each  contact  assembly  comprises  a conductive contact portion, a retention portion, a vertical offset portion and a conductive connection portion.   An insulative housing is provided having a plurality of contact assembly support cavities.   Each cavity includes a rib projecting therein which is adapted to pass between a pair of  normally  closed,  spring  members, which  define  the retention portion of the contact assembly.   The spring members are spread apart by the rib as the contact assembly is inserted into its respective cavity.  The rib is provided to have an extent such that when the contact assembly is fully inserted into the cavity, the spring members return to their closed position and engage a portion of the rib to resist removal of the contact assembly from the cavity.

Filed: 1993-05-17
Abstract: A joint between an end of a ceramic roll and a metal ferrule compensates for the differences in the thermal expansion properties of the joined materials. A plurality of thermodeformable bimetal elements are positioned in the space between the roll end and the ferrule to expand when the temperature increases to accommodate the greater thermal expansion of the ferrule relative to the roll and to provide a selected coupling strength in the joint at a given operating temperature.      The roll is preferably made from a vitreous, fused silica material and is suitable for supporting glass and metal in sheet, strip or plate form at elevated temperatures.

Title: Water saving device for flush toilet
Inventor: PIGEON E RICHARD
IPC: E03D1/14
Filed: 1993-05-19
Abstract: ABSTRACT         A water saving device for a flush toilet employs a piston cylinder unit utilizing water present in the tank to provide a controlled rate of closure of the flapper valve once the operating handle has been actuated.  This rate is designed to restore the flapper valve to the closed position after only a proportion, e.g. one third of the content of the water tank has been discharged, which amount will be satisfactory in many instances.  Where full discharge is required, either additional actuation of the operating handle is needed or flush handle is maintained pressed down.

Title: Palladium partial combustion catalysts and a process for using them
Inventor: DALLA BETTA RALPH
IPC: B01J23/46
Filed: 1991-11-26
Abstract: This invention is a catalyst comprising palladium on a support (102) and a partial combustion process in which the fuel is partially combusted using that catalyst. The palladium catalyst (106) may also comprise palladium mixed with metals selected from Group VIII or IB, may be graded (Fig. 1b) such as to have higher activity in the forward edge (112) of the catalyst, or may be placed on a support comprising zirconia. The choice of catalysts (106) and supports (102, 110) specified each solves a variety of problems dealing with the long term stability of the palladium as a partial combustion catalyst. The catalyst structure is stable in operation, has a comparatively low operating temperature, has a low temperature at which oxidation begins, and yet is not susceptible to temperature "runaway". The combustion gas produced by the catalytic process typically is at a temperature below the autocombustive temperature and may be used at that temperature or it may be fed to other combustion stages for further use in a gas turbine, furnace, boiler, or the like.

Title: A method of cooling and cleaning waste gas from an industrial process and apparatus therefor
Inventor: MCNEILL KEITH R
IPC: B01D53/81
Filed: 1992-06-04
Abstract: The invention relates to a method of cooling and cleaning waste gas from an industrial process wherein the waste gas under pressure is caused to pass transversely through a series of pebble bed heat exchangers, the passage of the waste gas through a pebble bed being effective to cause both heat exchange between the gases and the pebbles of the pebble bed, and also removal of a contaminant carried in the waste gas, and wherein the heated pebbles are subsequently used to transfer heat to a cooler gas. The invention also relates to apparatus for operating this method, including apparatus for cooling and cleaning waste gas from a glass melting furnace. The invention helps reduce levels of metal volatiles, oxides of nitrogen, oxides of sulphur, dioxins and particulates in the waste gas. It also makes use of the heat from the waste gas.

Patent CA-2115602-A1 (CA)
Inventor: DEVITO NICHOLAS M
IPC: H04Q3/00
Filed: 1994-02-14
Abstract: An arrangement for selectively routing traffic to alternate destinations. If the network or switch for accessing the primary destination is inaccessible (i.e., out of service), as opposed to simply being busy, calls are routed to an alternate destination; however, if the primary destination is simply busy, calls are not routed to any alternate destination. This is useful, for example, for emergency (E911) calls which are routed to alternate emergency bureaus only if the network or switch for accessing the home bureau is out of service. Alternatively, the tandem switch can select an alternate toll carrier on the basis of allocation of traffic to different alternate toll carriers. The same general kind of arrangement can be used to route calls to an alternate toll carrier if the preferred toll carrier selected by the customer is not accessible.

Title: Proportioning relay valve disabled by failed front braking circuit
Inventor: LATVALA BRUCE E
IPC: B60T8/26
Filed: 1994-02-23
Abstract: ABSTRACT OF THE DISCLOSURE A fluid pressure braking system for a tractor-trailer combination vehicle includes a proportioning relay valve which controls communication to the rear wheel brakes of the tractor. When the tractor pulls a trailer, the proportioning control within the relay valve is disabled, but when the vehicle is operated in the "bobtail" mode without pulling a trailer a proportioned brake application is effected in which the braking pressure communicated to the rear brake actuator is a predetermined percentage of that in the front wheel braking circuit.  The proportioning mechanism is also disabled when the front axle braking circuit malfunctions, so that upon loss of pressure of the front axle system, the driver effects a non-proportioned rear brake application.

Abstract: A process for treatment of caustic sulfide liquor by wet oxidation in a ferrous-based alloy system at temperatures less than about 175°C is described. The liquor is first analyzed for alkalinity consuming species and for nonsulfidic alkalinity. If excess alkalinity consuming species is present compared to nonsulfidic alkalinity, then additional nonsulfidic alkalinity is added to the raw liquor such that excess alkalinity is present during wet oxidation treatment, thus preventing excessive corrosion to the ferrous-base alloy system.
