Abstract: The invention relates to a method and system for permanently attaching a take-up screw (3) for taking-up the axial clearance of the armature shaft of a windscreen wiper motor. The take-up screw (3) is screwed axially into a bore (1) in the motor base (SM) until it reaches a stop position in relation to the armature shaft (6) locked on the screw, At least one surface discontinuity (2) is provided in the bore (1) and/or the thread of the screw (3), allowing the screw (3) to be screwed into the bore until it reaches the stop position. The screw (3) is screwed into the bore until the stop position is reached and a screw- and/or motor base-deformation strain (D) is applied at the discontinuity (2) in order to deform the side surface of the screw (3) and/or motor base (SM) and permanently attach the screw (3) and/or motor base by means of wedging in the discontinuity. The invention is suitable for the wind-screen wiper motors of motor vehicles.

The locking apparatus is mounted adjacent to but independent of the locators and provides for anti-rotation of the radial locators once installed.

Abstract: Retainer for threaded fasteners such as the cap screws that secure the end caps of roller bearing assemblies to railroad axles. A locking plate is constrained against rotation relative to the fastener, a lock ring having a plurality of openings disposed along a circular path is placed over the head of the fastener, with the fastener being received in a non-circular central opening in the ring and thereby constrained against rotation relative to the ring, and tabs extending from the locking plate and engaging the lock ring through the openings to retain the lock ring on the fastener and prevent the lock ring and fastener from turning. In the disclosed embodiments, the ring can be placed on the fastener in different rotative positions, and the number of tab openings is either a prime number or another number that is not divisible by factors of the number of ring positions, whereby the fastener can be selectively locked in a relatively large number of different positions no more than a few degrees apart.

Abstract: A retaining device for a split bolt connector which includes: a continuous wall that defines an aperture and at least one bendable tab extending upwardly from the wall or a member extending between opposing wall sections. The wall is adapted to accommodate the nut on a split bolt connector in the aperture and the at least one tab, or the member, is adapted to engage the slot in the split bolt after the nut is connected to the split bolt.

Abstract: A bolt lock locks a bolt against rotation on an output gear. The bolt lock includes a locking plate having a ring-shaped body encircling the head of the bolt and provided with locking tabs bendable into locking engagement with the flat sides of the bolt head to prevent the bolt from rotating. The plate is secured to the output gear by additional bolts. The ring-shaped body has additional locking tabs bendable into locking engagement with the flat sides of the heads of the additional bolts.

Abstract: The present invention relates to a connection between a spindle and a bearing assembly to retain the bearing assembly on the spindle. A combination lock washer and spindle bearing assembly is provided to include a spindle, thrust washer, lock washer and nut in which the lock washer simultaneously locks the inner thrust washer and an outer spindle nut. According to the present invention, the thrust washer, lock washer and nut may be oriented at any angle relative to one another allowing for infinite bearing adjustment positions.

Abstract: A memory system for a computational circuit having a pipeline includes at least one functional unit and an address generator that generates a memory address. A coherent cache memory is responsive to the address generator and is addressed by the memory address. The cache memory is capable of generating a cache memory output. A non-coherent directory-less associative memory is responsive to the address generator and is addressable by the memory address. The associative memory receives input data from the cache memory. The associative memory is capable of generating an associative memory output that is delivered to the functional unit. A comparison circuit compares the associative memory output to the cache memory output and asserts a miscompare signal when the associative memory output is not equal to the cache memory output.

Abstract: A robust fastener locking device (10, 20) prevents loosening of a fastener (F) used to attach to two parts (P1, P2) together. A plate (12, 22) fits against a part and abuts against at least two adjacent sides (S1, S2) of the part. The plate has an opening (14, 24) therein sized for a bolt to be inserted through the opening with the head of the bolt, or the nut (N) bearing against the plate when the fastener is secured in place. A portion of the plate adjacent the opening is deformable about the fastener after the fastener is secured in place to prevent subsequent rotation of the fastener which would loosen the fastener. In one embodiment, tabs (30a-30c) are formed adjacent the opening and can be bent about the portion of the fastener. The tab is broken off if the fastener needs to be removed, but the locking device can be reused.

Abstract: A sign clamp and method of installing signs to make the sign theft resistant, safe, and attractive in appearance by designing the clamp to block access to the bolt attaching the sign to the clamp and restricting the removal of the clamp.

Abstract: A marine drive (10) has a propeller (12) with a hub (14) mounted on a propeller shaft (22). A rear thrust hub (30) has one or more slots (40) spaced circumferentially around the propeller shaft. A nut (42) is threaded onto the propeller shaft to mount the propeller. A locking tab washer (60) around the propeller shaft between the nut and the propeller hub has one or more circumferentially spaced tabs (66) bendable forwardly into slots (40) of the rear thrust hub (30) and has ears (68) extending perpendicularly rearwardly from outer tips of the tabs externally of the slots. The ears may be gripped and pulled to bend the tabs rearwardly out of the slots, to enable removal of the nut, and hence removal of the propeller.

Abstract: A bonnet is locked to the body of a valve into which the bonnet screws by a sheet metal bonnet lock which includes a portion that will mate with facets on the bonnet or with the sides of the valve body. Another portion of the bonnet lock is then deformed to mate with the other of the bonnet facets or valve body sides. The portion of the bonnet lock that mates with the facets on the bonnet circumscribes the bonnet such that one portion of the bonnet lock is fixed to the bonnet and the other portion is fixed to the valve body following deformation of the bonnet lock to prevent the bonnet from turning relative to the valve body.
