Abstract: ABSTRACT OF THE DISCLOSURE        An oven for cooking food products compris-ing a substantially closed enclosure except for an inlet and an outlet in the end walls of the oven.  A heater means extends through the top wall of the enclosure into the cooking chamber for producing a gaseous cooking medium and suction fan means are provided on the enclosure top wall on either side of the heater means and in relatively closely spaced relation to the outlet of the heater means, and a source of moisture is disposed between the heater means outlet and the suction side of each of the fans for mixing moisture with the heated medium from the heater means.  A conveyor is adapted to receive food products and move the products through the oven from the inlet to the outlet thereof, and duct fingers are provided both above and below the conveyor for directing and impinging the heated gaseous cooking medium onto the food products being moved by the conveyor through the oven.  A second chamber separate from the cooking chamber is provided in communication with the pressure side of each of the fans and connected to the duct fingers for directing the mixture of heated gaseous medium and moisture withdrawn from the cooking chamber by the fans to the duct fingers to then be applied thereby to the food product.  Recycling of the cooking medium is accomplished and the oven is so constructed that cleaning thereof is materially facilitated.  A novel method of mass cooking of food product is also disclosed.

Abstract: SCROLL TYPE COMPRESSOR WITH VARIABLE DISPLACEMENT MECHANISM          ABSTRACT OF THE DISCLOSURE       A scroll type compressor with a variable displacement mecha-nism is disclosed and includes a housing having an inlet port and an outlet port. A fixed scroll is fixedly disposed within the housing and has a first circular end plate from which a first spiral element extends. An orbiting scroll includes a second spiral element interfitting with the first spiral element. The first circular end plate partitions an inner chamber of the compressor housing into a front suction chamber linked to the inlet port, and a rear chamber. The rear chamber is further divided by a wall of said housing into a dis-charge chamber linked to the fluid outlet port and an intermediate pressure chamber. At least one pair of holes is formed through the circular end plate of the fixed scroll forming a fluid channel between fluid pockets formed between the spiral elements of the scrolls and the intermediate pressure chamber. A communicating channel is formed through the circular end plate of the fixed scroll providing a fluid channel which links the intermediate pressure chamber with the front chamber. A control mechanism is disposed in the housing of the compressor adjacent the intermediate pressure chamber and controls the link of the intermediate pressure chamber to the suction chamber. The control mechanism includes a piston slidably disclosed within a cylinder, and a bellows element disposed within the piston. The bel-lows element includes a bellows and a valve element and is responsive to the suction pressure to control the link between the suction cham-ber and the central fluid pocket. The piston element is responsive to the pressure in the central fluid pocket to control the link between the intermediate pressure chamber and the suction chamber to con-trol the capacity of the compressor.

Title: Static-free interrogating connector for electric components
Inventor: LAUKS IMANTS R
IPC: H01R33/76
Filed: 1989-04-25
Granted: 1992-06-09
Abstract: Abstract of the Disclosure An improved connector for connection to and identification and testing of electric components such as integrated circuits is described which features a number of spring biased contact elements normally in contacting relation with a shorting bar. When a particular component is placed in a specified physical relation to the connector, a combination of exposed electrical contacts and nonconductive elements on the component to be tested displace specified ones of the contact members away from the shorting bars, providing a connection pattern which can be detected. At the same time, test signals can be applied to the electric component to be tested. The circuit may be identified and its specific parameters identified and characterized in a single operation according to the invention. Advantageously, the shorting bar is grounded so that any static charge on the component to be tested is grounded before the contact elements are displaced from the shorting bar.

Title: Tire leakage detection method for central tire inflation system
Inventor: BEVERLY JAMES A
IPC: B60C23/00
Filed: 1989-05-05
Granted: 1993-01-05
Abstract: ABSTRACT OF THE DISCLOSURE           A method for sensing and reacting to conditions indicative of leakage in a tire, the pressurization of which is measured and controlled by a CTIS.  The drawbacks of the prior art are minimized or eliminated by the provision of a CTIS control system having a method for detecting a leaking/damaged tire and/or a malfunctioning wheel and valve which fails to close at completion of a tire pressure measurement operation, and for taking corrective action, if necessary.  This is accomplished by causing the system to take a single, confirming pressure measurement about thirty seconds after completion of a pressure measurement or adjustment operation.  If a pressure decrease is sensed, a possible leakage condition is implied and corrected by means of inflation.  Upon successfully reaching desired tire pressure, the period between automatic pressure sensing/adjustments is considerably shortened.  The system will maintain this mode indefinitely until such condition is corrected.  By way of example, the period may be shortened to thirty seconds from fifteen to thirty minutes.
