Patent CA-2121320-A1 (CA)
Title: Car Catcher for a Roll-Off Hoist
Inventor: LUTZ THEODORE A
IPC: B60P1/64
Filed: 1994-04-14
Abstract: A car catcher is pivotally mounted to an elevated frame structure of a roll-off hoist at an end which protrudes rearwardly from a vehicle beyond the rear wheels thereof.  Chains establish a downwardly pivoted operative position of the car catcher by interconnecting the frame with the hoist.  A pivotal latch lever moved by the same actuator used to raise the catcher from an operative to an inoperative position is positioned to a confronting relation with a jam lock to prevent unwanted lifting of the catcher from the operative position.  The actuator moves the pivotal latch lever free and clear of the jam lock against the stop to allow, under control by an operator, pivotal movement of the car catcher to an inoperative position as desired during loading and off-loading operations by the hoist.

Abstract: A food mixer comprises a base (10, 12, 14), a supporting structure or column (16) upstanding from the base and an arm (18) projecting from the upper end of the column and carrying a mounting means for a mixing tool. The column is provided with a vertically extending V-section channel (24) on its bowl-facing side which, in use, receives part of the periphery of the mixing bowl so that the necessary horizontal extension of the head from the column is minimised. The mixing bowl is supported on a mixing bowl support (20) vertically movable on the column (16) to bring the bowl up to the mixing tool and lower the bowl therefrom. Except in the fully lowered position of the bowl support (20), the bowl is held captive on the bowl support by a pin (140) which is extended upwardly through a hole (68) in a flange (67) of the bowl, the flange being received in a slot (76) in the bowl carrier. The pin (140) is carried by a lifting mechanism for the bowl support (20) and is arranged with a degree of vertical lost motion relative to the bowl support (20), thus ensuring that the bowl is automatically locked into the bowl support before any lifting movement takes place and is not released until the bowl support has been fully lowered.

Patent CA-2142785-A1 (CA)
Title: Welding nozzle retaining ring with a tight fit
Inventor: COLLING RONALD W
IPC: B23K9/32
Filed: 1995-02-17
Abstract: A welding nozzle retaining ring has a polygon configuration with alternating peaks and straight segments.  One segment is cut.  The retaining ring is sized such that the peaks lie along a circle having a diameter that is slightly greater than the inner diameter of a welding gun nozzle or similar tubular component.  The midpoints of the inner surfaces of the retaining ring segments lie along a second circle having a diameter slightly smaller than the diameter of a groove in a welding gun adapter or similar cylindrical component.  With the retaining ring in the adapter groove, the welding nozzle is pushed over the adapter and the retaining ring.  The nozzle inner diameter contacts and depresses the peaks of the retaining ring and simultaneously causes the segments to bend around the adapter groove.  The retaining ring acts as a circumferential spring that provides a rigid radial connection between the nozzle and the adapter while enabling the nozzle to slide against friction along the adapter.  The polygon design of the welding nozzle retaining ring enables the nozzle and adapter to be manufactured with increased tolerances while providing improved performance.
