Patent CA-2082087-A1 (CA)
Inventor: LATSKO JAMES M
IPC: F16D67/02
Filed: 1992-11-04
Abstract: A coupling assembly includes a clutch assembly and a brake assembly.  The brake assembly includes an annular piston which is formed as one piece with a base member.  An annular cylinder chamber is formed as one piece with a second  member and telescopically receives the annular piston.  Force transmitting surfaces on the two members engage opposite sides of a friction disk.  The annular piston and cylinder extend around the outside of the friction disk to at least partially block a flow of contaminants in a radially inward direction toward the friction disk.  Passages are formed in a lower portion of the annular piston to accommodate a flow of cooling fluid and to enable any contaminants which enter the brake assembly to flow out of the brake assembly.  The brake assembly is advantageously urged to an engaged condition by spring assemblies which include posts and spring elements which extend into a space between the clutch assembly and a flange portion of a flywheel.  Arcuate spring retainer elements extend between outer end portions of the posts to hold the spring elements in place on the posts.  The clutch assembly is operated from a disengaged condition to an engaged condition by fluid pressure conducted from the brake assembly.

Patent CA-2086760-A1 (CA)
Title: Abrasive throwing wheel assemblies
Inventor: MACMILLAN WILLIAM R
IPC: B24C5/06
Filed: 1991-07-02
Abstract: An abrasive throwing wheel assembly comprises a throwing wheel having parallel annular side plates joined by spacers with the facing surfaces of the side plates having angularly-spaced registering throwing blade locating slots and throwing blades with lateral rails or edges for location in the slots.    The side wheels slots are wider than is customary aid contain central radially-extending projections. The lateral rails or edges of the throwing blades are grooved from the tips inwardly for at least part of their lengths. The throwing blades are located by interengagement between the sidewall projections and the rail or edge grooves of the blades. This reduces the surface contact between the blades and the side plates with consequent reduction in the accumulation of jamming abrasive during use. Throwing blade removal is thus facilitated. The wider slots remove the narrow radial flow of high velocity abrasive or shot between the slot walls and throwing blade side rails or edges which is customary thus reducing side plate, especially side plate rim, wear.

Title: Method of making a brazeable metal pipe having tube-insertion apertures formed with guide lugs
Inventor: NOBUSUE MITSURU
IPC: F28F21/08
Filed: 1993-01-12
Abstract: A method of making a brazeable metal pipe which has elliptical tube-insertion apertures and guide lugs extending from at least one of the opposite edges defining the minor axis of each aperture, with the guide lugs extending in the direction of insertion of flat tubes. The method in an embodiment comprises the steps of: bending a part of a raw strip, which may be previously embossed to form recesses, so as to provide a bulged portion arc-shaped in cross section and connected to at least one unbulged flat portions; pressing inwardly to form inward swells; subsequently punching each inward swell to provide the tube-insertion aperture so that at least one of the opposite edges located at ends of the minor axis of said aperture remains unpunched; and finally bending the at least one unbulged portions to produce the finished pipe. Alternatively, the method may comprise the step of: punching raw apertures through the raw strip so that each aperture has protrusions; bending it to form the bulged portion; bending the protrusions to give the guide lugs; and finally bending the unbulged portions, thus any complicated die is not needed and the pipe wall is protected well from being collapsed or deformed.

Title: Methods and systems for the negative pressure testing of underground storage tanks containing highly vaporous hydrocarbon liquids
Inventor: HORNER JACK R
IPC: G01M3/34
Filed: 1993-03-30
Abstract: A method and system for detecting a leak in a high vapor-evolving hydrocarbon liquid underground storage tank filled incompletely with the liquid, wherein there is a projecting fill pipe connected with the ullage which is filled with hydrocarbon vapor and air.  A vacuum source is connected to the fill pipe for withdrawing the atmosphere of the ullage and imposing a prescribed negative pressure.  While some of the drawn off vapor and much of the air is exhausted to atmosphere, a significant portion of the ullage content is recirculated to build the relative proportion of hydrocarbon vapor to air in the ullage.  The ullage is then isolated from the vacuum source and atmosphere, and allowed to stabilize over a predetermined time period with a reduced rate of hydrocarbon vapor release into the ullage.  The recirculation and stabilization are then repeated to achieve further saturation of the ullage with gasoline vapor and  vacuum is applied to the ullage to reach a predetermined threshold negative pressure in the ullage.  Over a predetermined time period successive negative pressure readings are taken to determine if there is a rate of decay which indicates the existence of a leak in the tank.
