Abstract:
Cooling apparatus for removing heat generated by friction between machine parts located within a liquid confining enclosure, for example, a seal surrounding the drive shaft of a motor driven pump used for below-ground pumping of sewage, the apparatus comprising a baffled chamber of novel construction which may be mounted on the pump motor housing and cooperates with a tubular heat exchanger, for automatic circulation, in closed circuit, of hot cooling liquid from the seal to the chamber, where it circulates in an orbital motion by virtue of the baffle arrangement, then passes to the tubular heat exchanger, and from there to the seal to cool it.
Abstract:
A device for the practice of the martial art of karate, simulating a board to be broken and comprising a pair of clamp members adapted to simulate the shape of the board to be broken; the clamps are adapted to hold pieces of material of varying strength to approximate the varying sizes of board to be broken and a padded striking area may be provided if desired.
Abstract:
An article carrier is provided for blow molding equipment which permits relatively simple exchange of the article gripping chuck portion of the carrier. The carrier includes a carrier body, a spindle rotatably supported by the body, an article gripping chuck removeably attached to the spindle and seals between the chuck and the spindle and between the chuck and a preform retained thereby. The chuck is provided with article gripping levers preferably rotatably supported by ball and socket joints. The levers have preform grasping projections at one end and first and second ball ends at the other end. The first ball end mates with the chuck body socket and the second ball end is engaged by a lever actuating ring slidably mounted on the outside of the chuck body.
Abstract:
A machine for high rate production of molecularly oriented thermoplastic bottles is disclosed. The machine is of the reheat-and-blow type. A blow molding station simultaneously blow molds article preforms arranged in matrices by modular article carriers for conveying the preforms and articles through the machine. The carriers are designed to retain the preforms throughout all operations of the machine from a preform load station through a thermal conditioning section, a blow molding station, and to a bottle eject station, thereby eliminating the need for other preform transferring apparatus. The article carriers together with the associated conveying apparatus comprise a sufficiently flexible structure that minor misalignments of the carriers with the blow molding mechanism do not adversely affect bottle production. Both loading of preforms and ejection of finished bottles are accomplished by operation upon matrices of preforms and bottles as defined by the carriers and conveyor lanes.
Abstract:
A game apparatus including a manipulatable container with a sinuous track having a concave surface mounted within the container and extending along a three dimensional path between a starting point and a finishing point, the track including a longitudinal twist between the starting point and the finishing point. A ball rolls along the track as the game is manipulated by a user. The container may contain two compartments communicating with one another through an aperture.

Abstract:
A bar feed apparatus for supplying elongated bar stock to the headstock of an automatic lathe. An elongated guide tube receives the stock and includes a hydraulic piston that controllably advances the stock toward the lathe. For cushioning the rotating bar stock against vibration within the tube, controlled quantities of hydraulic fluid is forced longitudinally into an annular clearance about the piston to and about the bar stock. A flexible seal secured downstream of the piston effects collapse during the forward stoke of the piston and effects a vacuum seal during a vacuum induced return stoke of the piston.
Abstract:
A flange finisher particularly well adapted for attachment to a flange of a motor vehicle as a pair of side walls joined by a web portion to form a U-shaped channel. Extending from one side wall into the channel are a plurality of small ribs. Extending from the other side wall into the channel and in opposition to the small ribs is a long foot wall which carries a plurality of ridges.
