Patent CA-2004459-A1 (CA)
Inventor: MILLER JEREMY P
IPC: F25D3/11
Filed: 1989-12-01
Abstract: Abstract TUNNEL FREEZER A tunnel freezer (1) comprises an elongate tunnel (2) which is inclined to the horizontal and which can be rotated about its longitudinal axis (X-X). The inside of the tunnel (2) is provided with a weir (6) which retains a pool (7) of liquid nitrogen between the weir (6) and the upper end (5) of the tunnel (2). Particles (12) to be frozen are introduced into the tunnel (2) on a conveyor (83 and drop into the pool (7) where they freeze substantially without aggregation. Rotation of the tunnel (2) carries the particles out of the liquid nitrogen and through the remainder of the tunnel (2) to the outlet end (13) of the tunnel (2). The frozen particles and the nitrogen vapour from the tunnel (2) pass through a common outlet (15) which is provided with a pivoting plate (16) which restricts the flow through the common outlet (15) so that the tunnel (2) operates at or slightly above atmospheric pressure thereby inhibiting ingress of moist air into the tunnel (2). Movement of particles through the tunnel (2) is facilitated by lifting bars (27, 28, 29, 30) which form part of a liner (33) which can be readily removed and replaced as desired. In a second embodiment the tunnel (2') is provided with a spiral ribbon (6') which forms a multiplicity of pools (7') extending along the tunnel (2'). This embodiment is particularly useful where the supply of frozen particles is variable.

Title: Process for dehydrohalogenating aromatic halides
Inventor: ABRAHAM THOMAS J JR
IPC: C07C1/26
Filed: 1989-12-20
Abstract: PROCESS FOR DEHYDROHALGENATING AROMATIC HALIDES      ABSTRACT Disclosed is a process for dehydrohalogenating an aromatic bromide or iodide by contacting the aromatic halide with hydrogen at elevated pressure in the presence of an alkyl halide-forming compound and a Group VIII metal catalyst.  The presence of the alkyl halide-forming compound, such as an alkanol, diol, triol or derivative thereof, facilitates the dehydrohalogenation reaction and permits the recovery of the halogen as alkyl halides from which the bromide and iodide values can be economically recovered.

Patent CA-2011614-A1 (CA)
Title: Vacuum operated circuit breaker
Inventor: HUM ANTHONY
IPC: H01H35/38
Filed: 1990-03-07
Abstract: ABSTRACT OF THE DISCLOSURE       A pair of electrical switches are operable by a movable lever between a first condition where the first switch is on and the second switch is off; to a second condition where the first switch is off and the second switch is on, by movement of a piston connected to a pressure source via an inlet port.          A flange is fixed on the piston shaft, and a compressed spring is mounted over the piston shaft between the flange and a sleeve surrounding the piston bore. A pressure close to ambient moves the flange which in turn moves the lever to the first position, while a pressure substantially less than ambient moves the flange in the direction to move the lever to the second position.  The switches are adapted to respond to the pressure of the input manifold of a motor vehicle, actuating the vehicle headlight circuit when the motor is running and the manifold pressure is very high, and actuating the starter/ignition circuit when the motor is not running and the manifold pressure is at ambient.

Title: Tapping attachment for a punch press
Inventor: BECKER MARK H
IPC: B23G1/16
Filed: 1990-04-18
Abstract: A tapping attachment (1) for threading a relatively large number of holes through a sheet metal part at a relatively low cost per hole. The tapping attachment includes a thrust bearing assembly (6) which is aligned with a turret-type punch press or the like and movable in response to an axially directed force generated by the punch press. The axially directed force applied from the press to the thrust bearing assembly is transferred to a spline shaft (26). The spline shaft is rotated within and moved linearly relative to a screw threaded roller nut (74), whereby the axially directed force is converted into a rotating force for advancing and turning a tap (80) at high speeds of rotation. A nitrogen reservoir (14) is provided so that a supply of gas is available for returning the thrust bearing assembly and the spline shaft to their initial positions in order that a new hole can be tapped in response to another axially directed force. Also provided is an oil reservoir (12) so that a supply of oil is available for lubricating and cooling the tap via an oil spout.

Title: Passenger automotive restraint generator
Inventor: CUNNINGHAM DONALD J
IPC: B60R21/26
Filed: 1990-06-01
Abstract: ABSTRACT OF THE DISCLOSURE      An impact extruded perforated aluminum housing contains a two-stage gas generator having a perforated bulkhead positioned between the stages.  Each stage includes a combustion chamber having an igniter and pyrotechnic charge therein with cooling and filter screens surrounding the combustion chamber.  The igniter of the first stage is fired by a squib responsively to an external electrical signal.  A rupturable barrier and a ball valve associated with the bulkhead control the flow of gas through the bulkhead and provide mechanical timing for ingition delay in the firing of the second stage after the first stage has been fired, and also provide pressure control after ignition of both stages to prevent repressurizing the first stage.  A rupturable foil barrier surrounding the combustion chamber in the first stage promotes a rapid rise in pressure therein and thus breakout sooner therefrom of gas to an airbag to be inflated.  A rupturable foil barrier surrounds the cooling and filter screens in the second stage and delays the breakout of gas therefrom to the airbag as the pressure rises, the rate of which pressure rise is less than that at which the pressure in the first stage rises.  The thickness of the foil barrier surrounding the combustion and filter screens is selected to be sufficiently less than that of the foil barrier surrounding the first stage combustion chamber so as to achieve substantial equalization of pressure in the first and second stages.

Abstract: ABSTRACT        An improved color picture tube includes an evacuated glass envelope having a rectangular faceplate panel. The panel includes a shadow mask assembly mounted therein by support means located at peripherally spaced positions within the panel. The support means provide compensation for thermal expansion of the shadow mask assembly. The compensation is a movement of the shadow mask assembly toward a screen of the tube as the shadow mask assembly expands. The support means at each of the spaced positions includes a stud attached to the glass envelope, a spring having an aperture therein engaging the stud, and a plate welded between the spring and the shadow mask assembly. The improvement comprises the combination of the spring being angled with respect to the shadow mask assembly to provide approximately half of the required compensation, and the plate being constructed of bimetallic materials and having appropriate thickness and length to provide the approximately remaining half of the required compensation.
