Abstract: A method for making a steering column locking assembly includes swaging a steering column tube and a steering column lock collar in such a manner that relative rotation between the two parts is resisted below a predetermined torque while relative rotation occurs at values of value above the predetermined value. A layer of plastics material may be provided between the two parts. Once the predetermined torque is overcome, then rotation between the two parts occurs, but ceases once the torque level drops below the predetermined level.

Abstract: A centrifugal pump has a rotating shaft (1) with a centrifugal impeller (3) mounted on it. The shaft (1) and impeller (3) are mounted within a stationary casing (7) and a mechanical seal (8) is provided where the shaft (1) passes out through the casing (7). In order to cool rubbing, sealing faces (9, 11) of the seal, fluid is caused to flow along a path from a tip (6) of the impeller, through the casing (7), into a seal chamber (14), through a clearance (15) between a hub (2) of the impeller and the casing (7) and returning through a port (16) in the impeller. In order to act as a vent for and to clear debris from the seal chamber (14), the clearance is located radially outwardly of and remote from the shaft (1). Especially those parts which are moving and are subject to wear can be replaceable.

Abstract: A set/operate mode switch is interposed between the door sensing or element door position activated switch and a remote monitoring station, to enable the remote station to monitor the door condition, or to enable a local signal assembly to monitor the door condition. The local signal assembly is made operative by the set/operate switch, so that the sensing element can be accurately set before turning door monitoring over to the remote station. While the local signal assembly is verifying the door condition, a shunt or shorting element keeps the remote monitoring station displaying a door open condition, all the while that the local signal assembly is operatively engaged, for security reasons. Only when the local signal assembly is isolated from the arrangement, can the remote monitoring station give a true signal of the door condition.

The ferrous conducting ring is disposed in the chamber within the cage was cast around the ring. Magnet means are disposed in each of the compartments and an annular sheathing is positioned over the compartments and bonded to the carrier such that the chamber and the compartments are hermetically sealed.

Abstract: A door handle/knob assembly a door handle/knob assembly includes a housing having an opening formed within the housing, and a shaft received within the opening of the housing. The shaft has an outer surface, a rib for axially retaining the shaft to a lip of the housing in one direction, and a pair of generally oppositely positioned recess formations formed in the outer surface of the shaft.

Abstract: In a snap connection system in which a shaft is inserted into a tube to a predetermined position, where co-operating surfaces on tube and shaft engage as in a laterally acting wedge. Two axially spaced spring loaded balls on one side of the tube urge the shaft into wedging engagement with the tube when in the pre-determined position. During insertion, a further spring loaded ball on the opposite side of the tube adjacent the wedge apex urges the shaft out of wedging engagement with the tube. A detent in the shaft accommodates this further ball at the predetermined position, locating the shaft axially and permitting wedging. The balls are biased by a spring sleeve and a tang thereon locates the sleeve on the tube. The tang may extend to the tube interior to coact with a detent in the shaft so that unclipping is necessary for disassembly. Alternatively, a spring loaded pin extending through sleeve and tube wall may accomplish the same end.
