Abstract: A lock assembly comprises a stator, a rotor pivoting in a bore in the stator and a plurality of stator piston/rotor piston pairings which are resiliently urged towards a key channel provided axially in the said rotor for receiving a coded key slidable in said channel and having flats each of which cooperates with one of the said pairings in order to displace the latter against the action of the said resilient means so that the generatrix of separation between each rotor piston and each stator piston of one pairing is at a tangent to the said rotor. The pairs of stator pistons and rotor pistons and their resilient restoring means are preassembled each in a radial bore in the stator. The radial bores are distributed angularly about the axis of the lock in at least one diametrical plane and are closed at their inner end by an abutment which is moved aside during insertion of the rotor.

Abstract: An expansion dowel assembly is made up of an axially elongated generally cylindrically shaped dowel body and at least one wedge-shaped expansion member formed monolithically with the dowel body. The dowel body has a first or leading end which is inserted first into a borehole within which the dowel body is to be anchored and an opposite second end. A severable web connects the expansion member to the first end of the dowel body. Before insertion into a borehole, the expansion member projects outwardly from the exterior surface of the dowel body. When the expansion dowel assembly is inserted into a borehole, the web is broken and the expansion member, now separated from the dowel body, is displaced away from the first end within a wedge-shaped recess in the exterior surface of the dowel body.

Abstract: The present invention relates to improvements in a self-bonding fastener and to a novel method of curing the bonding material during assembly line fabrication of sheet metal products. The fastener includes a headed self-threading screw member having its head undersurface formed with an annular axially extending lip. An upper portion of the screw thread is precoated with a thermo-setting adhesive which, when heated, will uniformly bond the fastener to a sheet metal plate. As the fastener is threaded through an undersized hole in a sheet metal member, such as an automobile body, the adhesive reliquifies and is stripped from the screw thread. The adhesive is then re-deposited uniformly to completely fill a closed chamber defined between the head undersurface and the opposed sheet metal surface sealed on its periphery by the annular lip which defines the axial dimension of the adhesive thickness.
