Abstract:
A coil assembly (10) includes a plastic bobbin (12) with wire (30,32) coiled thereon and coupled to the pins (38, 48, 54) of a connector (40). Plastic overmolding (60) covers wires (30,32) within bobbin (12) and fixes connector (40) relative to bobbin (12). A polyester bobbin (12) is made by injecting polyester into a mold having cavities (101, 151) to define the outer circumference of the bobbin and surrounding an arbor (106, 160) to define the inner circumference of the bobbin. The arbor (106, 160) with the molded bobbin (12) is removed from between the cavities (101, 151) and the bobbin (12) is slid laterally off the arbor by applying generally uniform pressure about a lateral edge (20, 22) of the bobbin so as not to warp same during the removal process.
Abstract:
A cluster assembly wherein a block has three longitudinal passageways. Connector clips are inserted into those passageways. The block has transverse holes in a front wall providing a communication to the clips so that pins from a header can pass through the holes and be connected to the clips. One of those holes has a boss surrounding it to improve the assembly of the cluster assembly to the three-pin header.
Abstract:
L'ensemble mécanique décrit comprend un bloc dans lequel sont ménagés trois passages longitudinaux, où sont insérées des pinces connectrices. Le bloc comporte des trous transversaux ménagés dans une paroi frontale, ce qui assure une communication avec les pinces, de sorte que les broches d'un collecteur puissent passer à travers les trous et être reliées aux pinces. L'un de ces trous est entouré par un bossage destiné à améliorer l'assemblage de l'ensemble mécanique avec le collecteur à trois broches.
Abstract:
A cluster assembly for application to a three prong header from the interior of a hermetically-sealed compressor. The cluster assembly includes an insulated block having spaced parallel passages in which connector clips with leads attached are disposed. The block has flanges at the ends of the passageways from which the leads project, the flanges having notches. The leads are placed in the notches and are twisted to lie outside the surfaces of the block, the block when applied spacing the leads away from the compressor housing.
Abstract:
A mold top lifting apparatus (121) for lifting a mold top (47) generally upwardly away from a mold bottom (48) supported on a movable support means (23) for movement in a generally horizontal direction, said mold top having generally vertical opposite side surfaces and a projecting means (53) laterally extending beyond the top of said side surfaces, said apparatus including gripping means (127-137) for resiliently engaging said mold top at that projecting means (53) and lifting means (138, 138A) for moving said gripping means upwardly, wherein said gripping means (127-137) are connected to the lifting means by movable frame means(122) and include roller means (130) spaced in horizontal direction for resilient engagement with said opposite surfaces of said mold top below said projecting means, and that before lifting of said gripping means said roller means are in such a vertical position roller means (130).
Abstract:
A coil assembly (31) having a core (32) and a winding (33) on the core (32), wherein a contact element (37, 38) electrically connected to the winding (33) is both mechanically clamped and bonded to the core (32). In an exemplary microcoil assembly (31) having a C-core (32), a generally U-shaped contact element (37, 38) is bonded to each foot (34) of the core by epoxy and mechanically clamped to the core foot (34) to hold the contact element in position while the epoxy cures. One end of the coil winding is soldered to one of the contact elements and the other end of the winding is soldered to the other contact element. The coil assembly (31) is subsequently soldered onto a printed circuit board. Each contact element (37, 38) may include a pin portion (51) to be inserted into a printed circuit board.
Abstract:
A caster with a braking apparatus includes a bracket and a wheel rotatably supported on the bracket, the wheel having a radially inwardly facing annular braking surface thereon between its axle and tread. A braking member has a braking surface thereon adjacent the braking surface on the wheel, and is supported for radial movement between braking and retracted positions in which the braking surface thereon is engaging and free of engagement with the braking surface on the wheel. Radial movement of the braking member is effected by a manually actuable lever. In a preferred embodiment, the bracket is pivotally supported on a bracket support and a further braking surface is provided on the bracket support. A braking element has a braking surface facing the braking surface on the bracket support and is moved by manual actuation of the lever between actuated and deactuated positions in which the braking surface thereon is respectively engaging and free of engagement with the braking surface on the bracket support.
