Title: Electrical plug assembly with releasable locking mechanism
Inventor: DOYLE KEVIN H
IPC: H01R13/639
Filed: 1994-08-09
Abstract: There is provided an electrical plug assembly comprising male and female plug members.  The male member has a plurality of electrical contact prongs and the female member has a plurality of electrical receptacle elements  for receiving the  contact prongs  to provide electrical contact therewith.   One of said plug members has a pair of  spaced apart  spring arms which extend generally parallel to one another.  The other of the plug members has a spaced pair of locking channels therein each being parallel with and receiving a respective one of the spring arms when the plug members are fitted together. The spring arms have  free distal ends each having a locking hook thereon.   Each of the locking channels has a  locking  shoulder  associated  therewith  adapted  to lockingly engage with a respective one of the locking hooks to secure the plug members together.   A pair of access  openings,  each  of  which  communicates  with a respective one of the locking channels, are arranged such that the distal ends of the spring arms are exposed to the exterior of the plug assembly.   This enables the spring arms to be manually deflected sufficiently via the access openings  as  to  release  said  locking hooks  from said shoulders to enable separation of the male and female plug members.

Title: Polyether-reinforced fiber-based materials
Inventor: TIEDEMAN GEORGE T
IPC: D21H17/57
Filed: 1993-03-12
Abstract: Polyether-reinforced fiber-based materials, and methods for their manufacture, are disclosed. A representative material is a sheetlike ply having on one or both faces thereof a polyether-impregnated stratum extending depthwise into the ply thickness di-mension no greater than about one-half the ply thickness dimension so as to leave a portion of the ply thickness dimension unim-pregnated with polyether. The materials can comprise plural superposed plies wherein at least one ply has at least one polyether-impregnated stratum, such as polyether-reinforced corrugated paperboard. The polyether-reinforced materials have excellent compression strength and foldability. Each polyether-reinforced stratum is made by controllably applying a low-viscosity liquid mixture of an epoxy resin and a hardener, wherein the epoxy resin is substantially non-prepolymerized, to a fibrous web surface, then curing the resin mixture. The polyether-reinforced materials can be folded after curing and are useful for making cartons and other products.

Title: Method and apparatus for draftless water jacket
Inventor: CLARK RICHARD J
IPC: F02B75/02
Filed: 1994-03-10
Abstract: The unitary cylinder liner (10) incorporating a water jacket (14) with water passages (12) and air ports (18) is vertically cast as a one piece unit. The water jacket (14) is draftless, allowing water to circulate therethrough more efficiently, increasing cooling capabilities. This one piece casting is made possible by the novel two piece core (30) which eliminates the need for welding of metal bands onto an outer surface of the liner to produce the jacket. The cylinder is constructed by vertical casting using a sectional mold (32).

Title: Screw conveyors, augers and flighting for use therein
Inventor: HAMILTON MICHAEL DOUGLAS
IPC: B21H3/12
Filed: 1993-09-13
Abstract: In a continuous screw conveyor or auger, the rotat-able screw member (12) comprises a helical radial blade (28) (known as "flighting") which is preferably carried on a central driving shaft (26). The flighting (28) is formed by rolling a rectangular metal strip of uniform thickness be-tween a pair of opposed, preferably offset, conical rolls (56, 58). In contrast to prior art rolls which have similar unstepped conical rolling surfaces, and produce a helical blade of which the radial thickness reduce progressively from the inner helical edge (30) of the blade to the outer helical edge (32), the present invention provides on at least one of those rolls (58) a stepped conical rolling sur-face (94) formed so as to exert less rolling pressure on an outer portion of the helical blade (28) being formed, there-by to produce a blade in which the outer portion is of a thickness (preferably uniform) which is no less than and preferably greater than that of an inner part of the blade lying immediately radially inwards thereof.

Title: Resilient molded shoe heels
Inventor: KRAJCIR DEZI ANTHONY
IPC: B29C44/10
Filed: 1995-05-04
Abstract: In a new method of molding a shoe heel a molding material is injected into a shoe heel mold and a fluid is injected into the heel body before it has set to form therein at least one enclosed hollow chamber therein which provides a different degree of resilience to heel strike forces at the location of the chamber. A plurality of closely adjacent chambers may be provided to obtain the same effect, particularly when the heel is shallow. In another method the chamber is formed by a preformed hollow element that is incorporated into the shoe heel by the molding operation.      The invention also includes apparatus for making such heels, and the heels when so made. The molded body may comprise a sole with an integral heel portion. A preformed body may be placed in the mold prior to a molding operation to ensure that the bottom chamber wall has a minimum thickness. The enclosed chamber may be vented to the ambient atmosphere or it may be sealed. The chamber when sealed may be at least partly filled with a gas or a liquid to adjust the degree of resilience, or it may be filled with a solid material of resilience different from that of the material from which the heel is molded.

Patent CA-2153961-A1 (CA)
Inventor: WEYER PAUL P
IPC: F16H25/20
Filed: 1995-07-14
Abstract: A fluid-powered rotary actuator having a body with a cylindrical interior sidewall portion. A rotatable shaft extends generally coaxially within the body. The shaft has a grooved, outwardly facing sidewall portion positioned within the body. A ring gear is positioned generally coaxially within the body and extends about the shaft. The ring gear has a grooved, inwardly facing sidewall portion. The ring gear is formed as a separate part from the body and the ring gear grooved sidewall portion is formed prior to positioning of the ring gear in the body. The ring gear is fixedly attached to the body to prevent rotation therebetween by a weld between the ring gear and the body interior sidewall portion. A stop member is engaged by the ring gear to limit movement of the ring gear toward the body first end during assembly of the ring gear in the body. In one embodiment, the ring gear is welded to a stop shoulder. A piston sleeve is mounted for reciprocal axial movement within the body in response to the selective application pressurized fluid thereto. A sleeve portion thereof has a grooved, inwardly facing sidewall portion engaging the shaft grooved sidewall portion and a grooved, outwardly facing sidewall portion engaged with the ring gear grooved sidewall portion to translate axial movement of the piston into clockwise or counterclockwise relative rotational movement between the shaft and the body. A method of manufacturing the actuator is also disclosed which includes forming the ring gear grooved sidewall prior to positioning of the ring gear in the body, and after positioning the ring gear in the body, fixedly attaching the ring gear to the body to prevent rotation therebetween by forming a weld between an attachment portion of the ring gear which projects axially away from the ring gear grooved sidewall portion and is axially spaced apart from the ring gear grooved sidewall portion by a separation distance sufficiently large that the heat of the weld does not distort the ring gear sufficient to impair operation of the actuator.
