Title: Heat exchanger with pressurized plenum

Granted: 1991-03-05
Abstract: HEAT EXCHANGER WITH PRESSURIZED PLENEM                   Abstract of the Disclosure Two flat radiators are arranged in a V, with a gap at the base of the V.  The ends of the radiators preferably are closed off to form a plenum chamber between the radiators.  A fan, preferably of the transverse flow type, is provided at the top of the radiators to pressurize the plenum chamber, which causes air to pass out through the radiator cores.  The fan also directs air from the top of the V towards the gap so that debris is directed out the gap.  The radiators may have a significantly higher fin density than in the conventional radiator since debris need not pass through the radiator cores.  In an alternative embodiment, four radiators are arranged in a nested double V, with a gap at the base of the outermost V.  Two fans, again preferably of the transverse flow type, are provided to direct air into the top of the V.  Operation is similar to the single V structure, except that in low cooling requirement conditions, one of the fans may be turned off.

Abstract: "ROTATION VARIATION TESTING MACHINE"               Abstract of the Disclosure Apparatus for testing a power transmission drive in-tended for use with a reciprocating engine by use of an electric drive motor in lieu of the engine.  The motor is provided in an adjustable input shaft driving unit which provides a variable speed drive of the power transmission drive corresponding to a variable speed drive effected by a reciprocating engine.  In one form, the drive speed is var-ied by a controlled brake which, in the illustrated embodi-ment, is an eddy current brake.  The brake may be utilized in conjunction with a variable speed input shaft driving unit for providing a second speed variation or may be used independently thereof.   Alternatively,  the electric motor may be operated by a control arranged to provide a speed variation of the electric motor corresponding accurately with the reciprocating engine characteristics.  Control cir-cuitry for effecting the desired brake control and motor control are disclosed.

Title: Vertical bale elevator
Inventor: CHECKLY ROBERT W
IPC: A01D87/12
Filed: 1989-01-23
Granted: 1992-05-12
Abstract: ABSTRACT A vertical bale elevator to transfer bales of hay, straw or the like between the ground and a barn has an elongated frame with two opposing augers mounted on opposite sides of the frame.  The frame contains guide means for the bales.  The augers are mirror images of one another and rotate in opposite directions to force a bale upward and rearward within a frame.  The guide means are arranged to receive a bale in the bottom section and discharge the bale in the top section.  The augers are powered by a single power source that can be reversed to move bales down the elevator rather than up.  When operating in reverse, it is usually desirable to make changes to the guide means.  The middle sections are made in various lengths so that the total height of the elevator can be varied.  With previous elevators, a chain rotates upward at a back and front of the elevator.  These previous elevators are much more complex.

Abstract: ABSTRACT A machine for making plastic bags from plastic film utilizes a rotatable drum having an adjustable diameter. The drum is constructed of a plurality of slats and includes a gear mechanism adapted for infinite variation of the drum diameter between a first smaller diameter and second larger diameter. A sealing blanket is provided for the drum and is automatically adjusted for different drum diameters to provide proper tension of the film as it passes around the expandable drum. The gear mechanism is operated manually or automatically by a motor mounted in the drum and can alter the drum diameter while the machine is running. A chill roll, a rotary handle hole punching unit, a perforator/cutter station and phase variators are also included. When the machine is used to make bags having printed material thereon, a comparator unit may also be used. The comparator unit uses an electric eye adjacent the drum to determine the spacing between activated sealing bars and an optical reader to determine the spacing between printing on the film. A microprocessor system compares these measured spacings to a preselected spacing interval. The microprocessor system activates the drum motor to adjust the spacing between heat seals and printed matter on the bag. The machine checks spacing on an ongoing basis to maintain proper spacing.

Abstract: There is provided a method for producing a self-supporting ceramic composite comprising (1) a ceramic matrix obtained by oxidation of an aluminum zinc alloy to form a polycrystalline oxidation reaction product of the metal (10) with an oxidant, and (2) one or more fillers (12) embedded by the matrix. The metal alloy (10) and permeable mass of filler (12) having at least one defined surface boundary (14) are oriented relative to each other so that formation of the oxidation reaction product will occur into said mass of filler (12) and in a direction towards said defined surface boundary (14). On heating the metal (10) to a first temperature above its melting point but below the melting point of said oxidation reaction product to form a body of molten parent metal, the molten metal reacts with said oxidant to form said oxidation reaction product which infiltrates said mass of filler (12) to said defined surface boundary (14). The resulting infiltrated mass is heated to a second temperature in order to remove or oxidize at least a substantial portion of any residual non-oxidized metallic constituents from or in said infiltrated mass without substantial formation of said oxidation reaction product beyond said defined surface boundary (14), thereby producing a self-supporting ceramic composite.
