Abstract: A method and apparatus for conserving energy in the operation of a conventional air conditioning system in a large building employing a water cooled condenser, an evaporator, a chilled water circuit, and a refrigerant compressor or heat source in an absorption-type air conditioner wherein the compressor or heat source is not energized and the water tubes in the evaporator are connected to the water tubes in the condenser to allow the water from the evaporator to flow directly into the water tubes of the condenser.

Abstract: An apparatus for deflashing a plastic article is disclosed. In operation, an operator places the article having flash in a nest which positions the article so that the flash is in a horizontal plane. A powered shuttle assembly picks the article up from the nest and places it upon an anvil. The anvil has striking edges which follow the line of juncture between the article and the flash. A punch apparatus is lowered onto the article and strikes the flash at the line of juncture disjoining the flash from the article. The power shuttle then removes the article without the flash to a discharge point. Optionally, at the discharge point, there may be provided an orientation assembly wich orients the deflashed article so that it may be placed upon a conveyor belt which carries the article to a collection point.

Abstract: An apparatus for cooling the neck moil of a blown container so that such moil can be easily removed from the container is disclosed. The apparatus has a main body portion which is connected to the rod of a blow pin cylinder so that the apparatus can be moved towards and away from the blow mold. The main body portion also has attached thereto the blow pin, a cutting collar and a rotation collar. To feed blow air to the blow pin, the main body portion provides an air channel. An annular cylinder is formed in the body portion which cylinder accepts an annular piston which piston has a cooling plate connected thereto. The cooling plate is designed to contact and flatten the moil against the cold blow mold so that the moil is cooled. By feeding compressed air to the cylinder at its upper end, the cooling plate is moved to contact the moil and by feeding compressed air to the cylinder bottom the cooling plate is retracted from the moil.

Abstract: A breathing apparatus is disclosed which fits into the mouth of a human between the teeth and cheeks. The apparatus functions to direct air from the front of the mouth to the back of the mouth and from there to the lungs. The apparatus features a ported curved tube which is open-ended and which has sufficient length to extend from the rear of the mouth on one side of the mouth along a path following the tooth line from one set of molars to the other and on to the rear of the mouth on that other side of the mouth. To facilitate flow of air from the front of the mouth to the rear, there is provided an intake opening located midway the tube so that said opening will be in a position at the front of the mouth. Exhaust openings are provided in conjunction with each open end of the apparatus for allowing passage of the air from the tube into the rear of the mouth and upper trachea.

Abstract: A drying oven for drying materials which give off noxious fumes is disclosed. The drying oven comprises a drying chamber having a circular top wall and a downwardly depending sidewall which is closed off at its bottom by a bottom wall. The circular top wall has an exhaust port which is eccentric therewith. The sidewall has means for introducing dry gas into the drying chamber through an intake port which is located directly beneath the exhaust port. A doorway is also provided for allowing the introduction of the material to be dried into the exhaust chamber. There is no requirement that the doorway have elaborate pressure seals as the pressures within the chamber do not rise appreciably above ambient pressures due to the unique location of the exhaust port with reference to the location of the introduction of the dry air.

Abstract: An injection blow molding machine for the production of thermoplastic containers is disclosed. The apparatus is a multistation apparatus with a preform being injection molded at one station, prior formed preforms being heat treated at optional heat treating stations and the heat treated preforms being blown at a blow mold station. An automatic removal station may be utilized subsequent to the blow mold station for removing the blown article from a carrying apparatus which is utilized to carry the preform from the injection station through the heat treatment stations to the blow mold stations and then to the optional removal stations.

Abstract: An adjustable dental impression tray including a primary unit and two complementary movable units slidably mounted telescopically on the primary unit for adjustment with respect thereto. The primary unit is provided with an outwardly extending flexible flap cooperable with a rigid tab and is adapted to receive and secure the movable unit in a predetermined adjusted position with respect to the primary unit.

Abstract: A package which includes a hollow container having a substantially rectangular mouth and a substantially rectangular, hollow, plastic plug for fitment to the container mouth is disclosed. The plug has a top wall with an opening therein through which ingredients from the container are dispensed. A hinged flap, which is integral with the top wall, is utilized to close off the opening.
