Title: Treadle refuse container
Inventor: WOLTERS RICHARD H
IPC: B65F1/14
Filed: 1989-11-01
Abstract: ABSTRACT         A treadle top container for refuse and the like comprises a lower container member interconnected with an upper container member by an upright container member.  The upright container member includes a hollow portion which communicates with a hollow portion of the lower container member and a hollow portion of the upper container member. A foot pedal is movably mounted adjacent to the lower container member while a lid is movably mounted adjacent to a rotatable portion of the upper container member.  The lid is shaped to selectively close an open marginal edge of the upper container member.  A flexible actuator is provided having one end operatively connected with the foot pedal and the other end operatively connected with a pivot rod located within and attached to the rotatable portion of the hollow portion of the upper container member.  The flexible actuator is configured in such a manner such that shifting the foot pedal between a first and second position rotates the pivot rod, which rotates the rotatable portion of the hollow portion of the upper container member, and moves the lid between the open and closed positions.  The actuator extends continuously from the foot pedal through the hollow portion of the lower container member, then through the hollow portion of the upright container member, and finally through the hollow portion of the upper container member to the pivot rod.  The actuator is disposed wholly within the container to prevent damage to the actuator and to facilitate sanitation of the container.

Title: Process for the electrophoretic deposition of barrier coatings on precious metals
Inventor: JEAN JAU-HO
IPC: C03B37/08
Filed: 1990-01-10
Abstract: ABSTRACT      Objects formed from precious metal are subject to costly weight-loss when they are subjected to lengthly periods at high temperature.  Such weight loss can be minimized by the electrophoretic deposition of a thin, uniform layer of ceramic, such as alumina, onto the precious metal.  Particular advantage is derived by using such coated precious metal in bushings for the manufacture of fiberglass.

IPC: F27D19/00
Filed: 1991-02-06
Abstract: A method and apparatus for determining the correct temperature of a heated coil of sheet material and for using said measurement to control a heat treating furnace.  The method includes providing a spot of heat resistant material having a known and constant emissivity on an uneven edge of the coil, the material of the spot remaining on peaks of the uneven edge.  The constant emissivity of the spot is independent of that of the edge, which edge changes and is substantially less than the true temperature of the edge.  The coil is heated and the spot emits infrared energy in an amount that is substantially representative of the correct temperature of the coil.  This infrared energy is sensed by an infrared detector aimed at the spot, the output of the energy being indicative of the true temperature of the edge and of the coil mass after it attains the temperature of the edge.

Altering the configuration of the ridges and grooves permits variation in spring rate.  The pads may be constructed of standard truck tire recap tread and arranged in a square configuration. Water is injected between the pads and grooves through inlets (50, 52) to cool the pads.  An aluminum plate (48) is mounted between first and second layers (40, 41) of tire recap tread to increase heat dissipation.
