Patent CA-2109786-A1 (CA)
Title: Pressure cooker
Inventor: NIESE KARL
IPC: A47J27/08
Filed: 1993-11-23
Abstract: ABSTRACT            A pressure cooker is proposed, whose lid has a dome, which for reducing the residual pressure and subsequent opening and whilst avoiding any rotary movement, has to be displaced solely in the vertical direction with respect to the actual cooker. Tongues projecting downwards between the dome edge and the cooker edge, in conjunction with guide slots provided in clips which hold together the cooker and the lid ensure radial opening and closing movements of the clips. A centring ring located in the dome and extending into the cooker facilitates the engagement of the lid on the cooker. The centring ring carries the sealing ring and the tongues and is loaded away from the dome by springs supported on the said dome. The dome and the centring ring are guided on one another by interengaging elements and can he locked together in the open position. On closing the pressure cooker the locking action is eliminated and the springs bring about both the closing displacement of the clips and also the positioning of the sealing ring with respect to its sealing surfaces on the dome and the cooker.

Title: Vibratory tumbling apparatus
Inventor: MUSSCHOOT ALBERT
IPC: B06B1/16
Filed: 1993-12-07
Abstract: A vibratory material handling apparatus is provided for mixing of materials, cleaning, blending and/or shake out of castings or the like. The apparatus comprises a container having a material supporting surface disposed along a generally horizontal longitudinal axis. The container has a material input end and a material discharge end axially spaced therefrom and it is resiliently mounted relative to a mounting surface. The apparatus also includes a vibration generator for producing a force to cause material within the container to be directed in a path of tumbling movement generally in a direction from the material input end toward the material discharge end of the container. With this arrangement, a tumbling assist mechanism is provided for applying a force to the material in addition to the force produced by the vibration generator to facilitate tumbling of the material as it moves along the path of tumbling movement.
Patent CA-2110867-A1 (CA)
Inventor: DUNNE MICHAEL J
IPC: B27L11/02
Filed: 1993-12-07
Abstract: A ring flaker has a housing with a back opening so that a blade ring mounted to an arbor assembly can be slid backwards away from the housing to allow the blade ring to be replaced without removing the housing.  This arrangement reduces the down time generally necessary to replace a blade ring in a ring flaker.  The back opening in the housing is of sufficient size to permit the blade ring to be axially withdrawn.  The arbor assembly has a slide arrangement on the ring flaker carriage and there is provision to use a hydraulic jack to move the arbor assembly on the slide arrangement for a distance sufficient for the blade ring to be disconnected for removal and replacement.

Title: Combined heat and power system
Inventor: KNOWLES JOSEPH
IPC: F02G5/04
Filed: 1992-07-02
Abstract: A combined heat and power (CPH) system for a building has an electrical generator (12) for supply power and a gas engine (14) which drives the generator, contained in a housing (30).

Inventor: BUTTERWORTH DAVID
IPC: A61B19/08
Filed: 1994-04-21
Abstract: A multi-element surgical drape includes a bottom sheet that is placed over a patient and a top sheet that is reversibly secured to the bottom sheet. The two sheets each have a fenestration, and the fenestrations are aligned to provide access to the surgical site. After the surgical procedure has been completed the two sheets are separated. The top sheet is contaminated ("red-bag") medical waste, while the bottom sheet can be disposed of as non-contaminated waste, recycled, or processed for reuse. A pouch is provided on the top surface of the top sheet near its fenestration for collecting fluid run-off during surgery. This pouch has a top edge and a bottom edge joined by two opposing side edges, with the side edges and bottom edges being sealed. The sealed top edge is detachable to permit opening of the pouch to receive fluid and then closing of the pouch to prevent leakage of the fluid. The invention permits a substantial reduction in the volume of red-bag waste generated by surgery.

Abstract: The present invention relates to a welding method in the manufacture of a spirally wound tube having a thermoplastic pro-file (1) of a mainly rectangular cross-section. A hole profile (1) is wound in a screw line form manner on a welding drum (2) si-multaneously as profile surfaces (1a, 1b), which are to be welded together are heated with hot air to a desired temperature, wher-eafter a welding mass (S) is extruded onto the heated profile surfaces (1a, 1b) in two streams along each edge of the profile surface (1a, 1b) and the welding mass coated hole profile portions are pressed together by means of a press roller (10). The inven-tion is characterized in that the welding is performed with a welding head (3) coupled to an extruder and provided with a welding keel (4), which from the outside is inserted between two profile surfaces (1a, 1b) to be welded together. Hat air (L1, L2) is blown out through two pairs of air openings (5, 7) in the welding keel (4) against the edge portions of the profile walls (1a, 1b). A keel nose (9) located between the two pairs of air openings is arranged to guide the four hot-air streams (L1, L2) and to pre-vent heating of the middle portion of the profile surfaces (1a, 1b). The extruded welding mass (S) is pressed out on the heat-ed portions of the profile surfaces (1a, 1b) through two pairs of welding mass openings (6, 8) in the rear section of the weld-ing keel (4). The welding pressure is maintained on a desired level by regulating the friction between the hole profile (1) and the welding drum (2).
