Abstract: A refrigeration control system having a temperature sensor responsive to condenser temperature. The sensor turns a condenser fan on and off in order to maintain the condenser temperature within pre-determined limits and also shuts down the refrigerant compressor in response to a predetermined maximum temperature.

Abstract: A beverage dispensing head and a method of dispensing that provide increased carbonation in a dispensed fountain beverage; the dispensing head has a discrete carbonated water decompression chamber in-between an upstream volumetric flow control and a downstream normally closed valve; the method includes the steps of propelling carbonated water through a flow control and then decompressing the carbonated water before it reaches the normally closed valve.

Abstract: The present invention comprises a measuring/positioning device. The invention herein is particularly designed for determining the elevation above a reference floor surface of an overhead object, such as pipe, conduit, duct work, structural steel and the like, the elevation of the center line of tubular objects, and the plumb position on the reference floor surface above which the center line of a tubular object lies. The present invention includes a sensing head that is pivotally secured to one end of an elongate measuring rod. The measuring rod has a measuring scale thereon and is slideably and telescopically engaged within a rigid elongate rectangular housing. The housing includes means for releasable securing the measuring rod at various positions there along, and includes read out points positioned thereon. A pair of level indicators are secured to the housing so that the measuring rod and housing can be positioned to extend through a true vertical line.

Abstract: An agitating and pumping device particularly for use with a beverage cooling and dispensing ice-bank system. The ice-bank includes a reservoir for holding water and refrigerating coils therein for cooling the water. A heat exchange circuit is in heat exchange relationship with the reservoir water for cooling beverage circulated therethrough. The agitating and pumping device includes an electric motor for driving a shaft having agitating blades secured thereto. A pump is magnetically coupled to the shaft and is fluidly connected to the heat exchange circuit and to a source of beverage. The motor is secured above the reservoir with the agitating blades and pump submerged in the reservoir water. Operation of the motor provides for agitating of the reservoir water and for the pumping of the beverage through the heat exchange circuit.

Abstract: The present invention concerns a method and tools for forming sheet metal, and in particular, a method for making a chase top from a stock rectangular piece of sheet metal. Creasing tools are described that each have a handle member and a creasing wheel suspended therefrom cooperates with a support lip to form first and second crease lines and first and second flange areas along each perimeter edge of the workpiece. A reinforcing ridge tool is shown having a handle member with a wheel rotatively suspended therefrom is used to indent the sheet metal along desired lines inwardly of the crease lines to form reinforcing ridges. A bending tool is described having cooperating bending members for clamping the workpiece along each second crease line for bending the workpiece there along to form vertical wall portions.

Abstract: A beverage cooling, carbonating and dispensing apparatus has a refrigerator cabinet having a cold air cooling chamber, a cold beverage reservoir and carbonator in the cooling chamber, an outlet from the reservoir to a dispensing valve, and a spring-like helically coiled thermally conductive precooler secured to a beverage inlet of the reservoir, the precooler is suspended in the cold air chamber and has a substantial restriction to flow of beverage therethrough so that the refilling flow into the reservoir is very slow and is cooled to about 40 degrees F. (4.4 degrees C.) before admittance into the reservoir, so the entire contents of the reservoir can be dispensed without warmup or loss of carbonation.

Abstract: The present invention comprises a device for holding and organizing the major valve train components of an internal combustion engine during disassembly thereof. The organizing device includes a collapsible valve suspending rack, a valve train component organizing portion and a residue tray. The valve rack includes a suspending portion having a plurality of holes for providing for the suspension of engine valves therefrom. The organizing portion includes parallel rows of flat support portions having valve spring holding pins, and push rod and lifter retaining holes. The residue tray provides for holding the rack and organizing portion, and for retaining any oil or other liquids that may drain from the engine components.

Abstract: The present invention concerns a method and device for optimizing the air-fuel mixture burn rates of an internal combustion engine in accordance with detonation limited control parameters during low speed, light and heavy load operating conditions. In particular, the present invention is preferably used with an engine having variable valve events that provide for a low speed, small valve event, and for earlier than normal intake valve closing. The method and device herein including phasing control of the operation of the camshaft of the engine with the operation of the crankshaft of the engine. The invention herein also including sensing of engine load and detonation. The phasing is controlled by a servo motor in response to signals produced from the sensing of load demand and/or detonation.

Abstract: A method of and apparatus for controlling the thickness of an ice bank as might typically be found in the beverage dispenser field, wherein the method has the steps of attaching an ice sensor to the cooling coils of the ice bank reservoir, selecting and setting an operatively fixed but user-selectable space between the sensor and the cooling coils, freezing a portion of water to form the ice bank, sensing the formation of ice at the sensor, and controlling the freezing responsive to the sensing of ice. The apparatus is usually flat and manufactured from a single piece of injection molded plastic. Included within a first region are a curved portion for interweaving between adjacent cooling coils, and a strap for wrapping around an additional cooling coil spaced from the adjacent coils. The apparatus bends to form a substantially triangular support for the sensor. The sensor is retained by clips to the second region and extends outside of the triangular area bounded by the three portions of the apparatus.

Abstract: A rigid thermoplastic manifold for the distribution of pressurized carbonated water has an elongate tubular thermoplastic body with a plurality of apertures spaced along its length, a plurality of identical thermoplastic outlet fittings which each have at inlet spud with a sonic energy director and a pair of arcuate sonic energy directors spaced one on each side from the spud, each outlet fitting being fastened and sealed to the tube with three discrete sonic welds. A method of making the manifold is also provided.

Abstract: A new class of compounds, perfluoroacyl modified cellulose acetate polymers, has been synthesized. A novel method of preparation of these compounds is shown. It was discovered that these polymers can be used to form membranes having superior characteristics. The perfluoroacyl modification allows these polymers to be cast as ultrathin membranes resulting in improved gas flux rates while maintaining a high degree of selectivity, improved resistance to water, and the elimination of post treatment procedures. Furthermore these polymers can be spun as hollow fibers.

Abstract: A grain handling device for the receiving and transporting of grain and the like with the primary aspects of this invention being related to ground level receiving of such grain from a carrier, such as a truck, holding and controlling such grain and transporting such grain to a storage bin, typically at an elevation higher than that of the grain delivery carrier. The primary aspects of this invention are the positive control of the grain received from the truck into the grain receiving bin through the use of a valve disposed in the grain bin at the outlet thereof for control of the rate of flow of the grain from the grain holding bin into a grain transport. The valve is configured in a unique way to cooperate with sloping bin walls and the bin outlet to substantially seal such outlet in the valve closed position and to prevent bridging of grain within the grain receiving bin, thereby eliminating plugging at the grain bin outlet.
