Abstract: ABSTRACT        HEATER DEVICE FOR HEATING PORTIONS OF SHOE                 UPPERS    A clamp-type heater for heating shoe upper portions prior to molding them comprises an inner metal form and a cooperating outer band of silicone rubber material.  The form is heated e.g. by a cartridge heater while the band is heated by a radiant heater arranged about its outer surface.  When the inner form carries a shoe upper portion into the band, the 1atter wraps around the portion and clamps it about the form to ensure efficient heat transfer.          The temperature of the outer band is sensed by a thermistor which is accommodated in a tube secured by adhesive to the outer surface of the outer band.  More particularly, the tube is secured to the band by a line contact and its longitudinal axis extends perpendicular to the direction in which the band is stretched during the operation of the device.  The thermis-tor cooperates with an electronic controller to maintain the band at the control temperature set, without any wide fluctuations which are characteristic of e.g. thermostatic control means.  The tube is of a silicone rubber material having similar heat-conductive properties to those of the band.

Abstract: EMERGENCY DESCENT DEVICE          ABSTRACT OF THE DISCLOSURE         This invention relates to a fire escape for high rise buildings.  Cables are automatically lowered from the roof of the building, and once they have descended, brake apparatus is slipped over each cable to be used from various levels of the building.  A person is suspended from each brake apparatus, and is controllably lowered to the ground.  Since the brake apparatus can be attached anywhere along the cable without prethreading, a plurality of persons can be lowered at the same time, and the same cable can be used repeatedly by many people.

Abstract: IMPROVED HOIST OR THE LIKE          Abstract of the Disclosure The improved hoist includes a direct current brake and a control therefor.  In the brake control, the AC current is rectified with DC current being sent to the brake solenoid. When the hoist is operating, the brake solenoid is energized to hold the brake in the unactivated position.  A timer and power reduction means are utilized to reduce the power on the solenoid while the hoist is in operation, thus reducing the energy expended while the hoist is in operation.  The operating speed of the brake is increased since less power must be dissipated from the solenoid before the brake can be actuated.
