Abstract: An elevator cover assembly having a cover pad and a trim with openings for receiving a hanging knob inside the elevator is disclosed. The trim is a separate piece attached to the elevator cover after openings are made in the trim. The trim slits formed therein are sized and positioned to receive hanging knobs. The trim is made of a flexible material that can be deformed to broaden the openings to more easily position the openings over the knobs.

Abstract: An improved expandable shoe and inner assembly are disclosed. The expandable shoe includes an outer shell and an adjustable inner assembly is disposed within the outer shell. The inner assembly has a first board portion and a second board portion in overlapping engagement with each other and a control to adjust the position of the first board portion relative to the second board portion. The control includes a locking mechanism shaped to engage and hold one of the first and second board portions, a biasing mechanism to bias the locking mechanism into engagement with one of the first and second board portions; and an urging member having a proximal portion external of the shoe outer shell and positioned and movable transversely to a longitudinal direction of the shoe and in transverse alignment with the locking mechanism.

Abstract: A phosphor bronze alloy which contains 0.4 to 3.0 weight % Ni, 0.1 to 1.0 weight % Si, 0.01 to 0.35 weight % P, 1.0 to 11.0 weight % Sn with remainder being substantially Cu.

Abstract: A three ring binder includes a spine, front cover and back cover, each of which includes a substantially solid base plate and an outer plastic shell. The spine and front cover each includes a rectangular picture frame, the outer edges of which are aligned with and welded to the bottom and side edges of the spine and cover. A clear plastic membrane is secured to the frame's interior covering the opening in the picture frame. The frame top edges are spaced inwardly and free of the shell to form insert pockets. Display inserts are slidably mounted within the insert pockets defined by the frames. The spine insert includes an upper folded edge, and includes an outer pin head. Pulling upwardly on the pin head withdraws the insert. Mount-mats of a semi-solid paper are provided in the pockets to receive thin, flexible paper for insertion into the frame pockets. The inserted mat holds the display material with the insert pocket. The frame may be of thin flexible opaque plastic sheet material less than 0.

Abstract: A pre-fabricated pavement slab having a binder distribution system and an interconnection system formed for attachment of the bottom surface of the slab, wherein both the binder distribution system and the interconnection system are accessible from the top surface of the slab, such that the binder material may be injected into the binder distribution and interconnection systems from the top surface of the slab.

Display inserts are slidably mounted within the insert pockets defined by the frames. The spine insert includes an upper folded edge. An L-shaped member extends through an opening in the folded edge, and includes an outer pin head. Pulling upwardly on the pin head withdraws the insert. Mount mats of a semi-solid paper are provided in the pockets to receive thin, flexible paper for insertion into the frame pockets. The inserted mat holds the display material with the insert pocket.

Abstract: A high frequency water cooled transformer for coupling a power source to an induction heating coil and which serves to convert the output of the power source into values appropriate for the induction heating coil, and to match the impedance of the power source with the impedance of the heating coil for maximum power transfer efficiency. The primary of the transformer is adapted to be connected to the power source and the secondary is adapted to be connected to the induction heating coil. The transformer includes a secondary formed of two parallel self-supporting elongated open-ended hollow electrically conductive cylindrical members. A pair of electrically conductive terminal blocks are respectively mounted on one of the ends of the cylinders and electrically connected to the cylinders. The primary winding is wound longitudinally through the two secondary cylinders, and the ends of the primary winding are connected to appropriate terminal pins.

Abstract: A clamp assembly includes a yoke having a rectangular configuration and circumscribes a rectangular space, and a pair of spaced electrically conductive terminal bodies mounted in the rectangular space of the yoke. The terminal bodies are adapted to be connected to corresponding electrical terminals of an induction heating machine. A clamp pad is slidably mounted in the rectangular space of the yoke and is moveable vertically toward and away from the tops of the terminal bodies. An induction coil assembly including a hollow induction coil and a pair of spaced parallel elongated terminal bars is provided, with the terminal bars removably clamped between the clamp pad and the tops of the terminal bodies.

Abstract: A mortising machine adapted for connection to a conventional electric motor includes a frame having rotatably mounted therein a helically-grooved shaft on which is threadedly mounted a router assembly carrying a rotatable router bit for reciprocation along the grooved shaft upon its rotation. The shaft of the router bit and the grooved shaft are both driven from a drive shaft journaled in the frame by a drive connection arrangement of pulleys and timing belts to simultaneously rotate and reciprocate the router bit for cutting a linear mortised slot. For driving the shaft of the router bit, the drive arrangement includes a pulley on each of the drive shaft and router bit shaft, a traveling idler pulley mounted on an arm pivoted on the router assembly, and a timing belt trained about the pulleys.

Abstract: A light fixture mounting device is disclosed wherein a service outlet box has a mounting adaptor with light fixture suspension means providing temporary suspension of a light fixture during installation and connection of the electrical wiring and subsequent maintenance.
