Patent EP-0341823-A2 (EP)
Inventor: BREWER EDWARD L
IPC: F16J13/16
Filed: 1989-04-10
Abstract: A simple to operate locking mechanism for a pressure cooker, the locking mechanism having a locking arm rotatable from a fully open to a fully locked position, the locking arm (11) being operatively connected to a cam shaft assembly (30) which is rotatable with the locking arm, the cam shaft assembly being slidably axially in a cam shaft sleeve (40) rotatably mounted in a displacement member (20) which causes the cam shaft assembly to be axially displaced as it is rotated by the locking arm, the cam shaft assembly being moveable from a retracted to an extended position as the locking arm moves from a fully open to an intermediate position. A safety mechanism (51-57) is provided to prevent rotation of the locking arm from the intermediate to the fully locked position in the event the cam shaft assembly is not fully extended. A pressure responsive safety mechanism (58, 59) is also provided to prevent opening movement of the locking mechanism in the event the cooker is under pressure.

Abstract: Insulated electric wire is manufactured by the continuous extrusion of a tube of polymeric insulator (13), drawing an electric conductor (10) axially through the tube (13) the conductor drawing the tube to cause radial shrinkage of the tube onto the conductor, and directing cooling fluid (20) (via orifices 22, 23) at an intermediate portion (14) of the insulator tube so that the molecular orientation of the polymeric insulator is frozen and maintained. This reduces, and renders controllable, the force needed to strip the insulator.

Abstract: A heat sink element (26), preferably one formed with a relatively large surface area from which thermal energy can be transferred convectively and radiatively to an ambient atmosphere, with or without forced fluid flow, is held forcibly in contact with a heat transmitting surface of a heat source (22) for thermal conduction of heat therefrom. A heat sink attachment element (28) affixed to the heat sink element has flexibly attached castellated extensions (56) formed with tapered end teeth contacting a correspondingly inclined surface of the heat source. The castellated extensions are each subjected to a continual externally applied force and the total resultant force thereof, holding the heat sink element to the heat source, thereby can be maintained or will increase as the assembly experiences thermal cycling and mechanical disturbances during use. The effectiveness of thermally conductive contact between the heat sink and heat source therefore does not deteriorate during prolonged use.

Abstract: The invention relates to coating composition, coated articles of manufacture, and to the formation of the coated articles. The coating is an energy-beam set resin containing fluid containing heat- expandable, fluid-encapsulating hollow spheres in the resin. The coating of a substrate, such as a communication line material, is accomplished by coating the material with a resin mixture containing expandable spheres and then exposing the coated material to an energy-beam source for a period of time to cure the resin and expand the spheres. The coating is applied to at least one filament of a communication line material. Such filaments can be gathered into bundles which are first extrusion coated with a thermoplastic polymer before being coated with the resin mixture. The composition of the resin material can be varied by changing the volume percent of the hollow spheres present in the resin mixture.

Abstract: Mine having a specific direction of action, with a first positioning device for the automatic alignment of the mine in a desired position after it has been brought into a predetermined target zone. Where remotely laid mines are concerned, there is the possibility that, depending on the type of terrain, in particular instances they will not assume their intended position or will be overturned as a result of external forces. In view of this, the mine (1) is equipped with at least one further positioning device (6), by means of which it can be aligned anew in the desired position if the desired position is not obtained by means of the first positioning device or after a variation in position. Preferably, at the same time, the first positioning device (4) or the particular preceding one can be separated from the mine (1) before the second positioning device (6) or the particular following one comes into operation. <IMAGE>
