Patent CA-2071313-A1 (CA)
Title: Connector for sealing stacked filter elements
Inventor: CONNORS JAMES T JR
IPC: B01D29/11
Filed: 1992-06-16
Abstract: ABSTRACT OF THE DISCLOSURE    A novel sealing connector is provided for sealing a stack of filter units in a filter housing.  The sealing connector has a base portion, a compression generating member, and means for selectively attaching the base portion to the end of a filter unit.  In the illustrated embodiment, the sealing connector has a annular, disk-shaped base having top and bottom sides, a compression-generating member, such as a spring, attached to one of the sides, and a female attaching means for attaching to a male connection portion of a male end connector.  The female attaching means has a connecting portion formed by an outer wall, which extends along the outer periphery of the base and extends outwardly from the base portion, and a flange, which extends from the end of the wall in the radial direction of the base portion.     In order to attach the sealing connector to the end connector of the filter unit, the outer wall and flange form a socket for receiving the male connecting portion of the end connector.  In order to selectively attach the sealing connector to the end connector, the female attaching means is substantially aligned with the male connecting portion and an axial force is exerted so that the male latch member slides into the socket.  The male latch member engages and hooks the flange of the female attaching means so that the sealing connector is integrally attached to the end connector.  Since the outer diameter of the male latch member is slightly larger than the inner diameter of the flange of the female attaching means the connecting portions of the sealing connector and/or the end connector are resilient so that can bend slightly in order to slide into socket.

Title: Method of and means for driving a pneumatic engine
Inventor: BARTH WOLFGANG
IPC: F01B17/02
Filed: 1991-05-03
Abstract: The invention relates to a process for running a pneumatic motor using a running system so designed that it comprises a plurality of working cylinders connected in series, each of which has a closed pressure expansion chamber which contains, throughout the entire operating time, a uniform quantity of compressed air, the pressure of which applied before the working stroke drives the piston head through the stroke of the necessary working power after the working stroke correspondingly to its original expanding pressure and in each working cylinder there is a pressure by-pass chamber connected to an injection pressure line linked to the compressed air source, which is connected to the pressure by-pass chamber of all the other working pressure cylinders via controllable relay valves and is also connected to a pressure by-pass line linking the pressure by-pass chambers of all working pressure cylinders together via controllable relay valves in such a way that the working fluid expanding out of the pressure by-pass chamber via the pressure by-pass line controllable by relay valves can be stored in the individual pressure by-pass chambers of the subsequent working cylinders (see table) and, for the further raising of the pneumatic pressure in the pressure expansion chamber, pressure fluid partly stored in the pressure by-pass chambers of all subsequent working cylinders can be taken via the relay-controlled power by-pass line into the pressure by-pass chamber and the pressure fluid needed for applying the necessary pressure can be taken via the injection pressure line from the compressed air source so that the piston head acting as the working piston moves upwards and the pressure needed for the next working stroke is taken into the pressure expansion chamber. As a device fitted behind a motor, i.e. a drive system, this pneumatic motor provides more energy in the form of work than is needed to maintain the system within the operating process.

Title: Innerbody flex tab cosmetic dispenser
Inventor: HOLLOWAY THOMAS F
IPC: A45D40/06
Filed: 1992-10-28
Abstract: A cosmetic preparation dispenser is provided that has flex tabs formed on the lower end of the innerbody that bear against the cam sleeve to provide a desirable swivel torque,  and which extend inwardly to engage or confine the elevator cup when it is fully retracted, to prevent vibration of the cup within the innerbody. Damage to a cosmetic pomade held in the cup is less likely during transport because the cup is secured. The flex tabs also minimize pomade back-off during consumer use by providing a frictional braking effect.

Title: Exhaust pressurizing control for a fluid system
Inventor: BUDZICH TADEUSZ
IPC: F15B21/047
Filed: 1991-01-22
Abstract: Fluid systems having fluid motors which control aiding type loads many times have problems with cavitation in one end of the fluid type motor during lowering thereof. It is desirable to eliminate all cavitation in the fluid motor during operation. In order to eliminate cavitation during lowering of an aiding type load and to provide a positive pressure therein, the subject arrangement provides an exhaust pressurizing control (184) for use in a fluid system (10). The exhaust pressurizing control (184) includes an exhaust manifold means (80) having selector means (88) to provide a positive pressure in the exhaust manifold means (80) during lowering of an aiding type load (W1). The selector means (88) includes pressure limiting and unloading means (90) operative to provide a positive pressure in the exhaust manifold means (80) during lowering of the aiding type load (W1) and to unload the pressurized fluid in the exhaust manifold means (80) during raising of a resisting type load (W1). The pressurized fluid in the exhaust manifold means (80) is available to the fluid motor (16) through anti-cavitational valve means (109). This arrangement effectively eliminates cavitation in the fluid motor (16).
Patent CA-2084836-A1 (CA)
Inventor: TOMEK MARTIN L
IPC: E21B47/01
Filed: 1992-12-08
Abstract: The present disclosure is directed to a shock absorbing device for threading in a tubing string for running delicate instruments into a well borehole where they are in near proximity to explosives which might otherwise be detonate. This particularly is important in a well borehole which is filled with a standing column of liquid which transmits the shock waves quite readily. This is a separate assembly which can be threaded in the tubing string and has a pin and box connection for that. Moreover, it is formed of an outer mandrel surrounding connected inner upper and inner lower mandrels; the inner mandrels define annular spaces for receiving shock absorbers defined by alternating thin layers of metal and rubber; the metal and rubber washers have different shock wave impedances and tend therefore to absorb shock waves traveling either upwardly or downwardly in the well borehole.

Abstract: An oxygen sensor is based on a thin film of a compound oxide supported on a substrate such as quartz.      The compound oxide has a general formula ABO2.5+x, where A is an element of the lanthanum family, alkaline earth metal or their mixture, and B is a transition metal or a mixture of transition metals. X is a variable number, changing from about 0 to about 0.5 between the reversible oxygen-deplete and oxygen-rich forms of the oxide. In an elevated temperature and oxygen-containing atmosphere, the thin film can undergo reversible bulk oxidation resulting in a detectable change of its physical properties such as mass, optical transmissivity and electrical resistance.

Title: Elbow fittings for double containment pipe assemblies
Inventor: ZIU CHRISTOPHER G
IPC: F16L39/00
Filed: 1992-04-03
Abstract: A double containment pipe assembly having curved portions formed from elbow fittings (10, 12) extending between straight portions of an inner and outer concentric pipe assembly. The elbows or curved fittings (10, 12) occupy the same angular sector of a circle and are concentric to each other. The spacing between the inner and outer curved surfaces of the fittings of the elbows (10, 12) is consistent and the same throughout the radius of curvature of the elbows. This provides maximum protection against contact of the inner and outer fittings (10, 12) during thermal expansion and contraction of the pipe. Straight portions of pipe (18, 20) can be secured to opposite faces (14, 16) of the fittings for ease of field fabrication of the double containment pipe assembly. The straight portions may be butt-welded or joined by butt-and-wrap techniques to the end faces (14, 16) of the fittings or nested in or over sockets (14', 16') provided at the end faces.
