  • Publication number: 20200154947
    Abstract: Methods for adjusting the pressure in a cooking chamber of a pressure fryer are provided. The pressure inside the cooking chamber is determined in response to detecting closure of a valve that vents the cooking chamber. The pressure in the chamber is compared to a predetermined pressure. If the pressure in the chamber is less than the predetermined pressure, a pressure assist system is activated. The pressure assist system includes an air pump and/or pressure source, and when activated, supplies a gas to the cooking chamber to increase the pressure in the cooking chamber. The pressure may be determined at a predetermined time after closure of the valve, and an amount of gas to be added to the cooking chamber determined based on a difference between the measured pressure and the predetermined pressure.

  • Publication number: 20090178477
    Abstract: The pressure at a pressure sensor is cycled between a higher (upstream) pressure and a lower (downstream) pressure. The pressure sensor senses the higher and lower pressures, and the difference therebetween is calculated and output. The pressure sensor can be a “single-pressure” pressure sensor (gage or absolute) where the pressure sensor is alternately connected between the two pressures.

    Abstract: A method for the singulation of hybrid circuits from a pre-scribed plate containing hybrid circuits or made of other brittle materials. The method includes the steps of providing a platen used to support the hybrid plate and which has a surface comprised of a series of sections each angled downward from its adjacent section, aligning the plate on the platen so that the scribe lines align with the surface discontinuities at the angles between the sections, securing the plate to the platen with vacuum pressure, creating a pressure differential between a space above the plate and a space below the plate, and applying the pressure differential to sequentially break the plate along the pre-scribed lines by forcing the plate against the angles.

  • Patent number: 6070607
    Abstract: A control system for producing first and second fluid sources whose pressure difference is regulated to a desired value in response to four fluid supplies of independently variable pressures. The pressure of the first fluid source is not allowed to decrease substantially below the third fluid supply pressure or rise substantially higher than the desired value above the pressure of the third fluid supply. The pressure of the second fluid source is not allowed to rise substantially above the fourth fluid supply pressure or decrease substantially lower than the desired value below the pressure of the third fluid supply. The system may consist of a diaphragm-type pressure regulator which is responsive to the difference in pressure of the two fluid sources. One side of the regulator is selectively valved to connect to one of two pressure supplies while the other side is selectively valved to connect to one of two additional pressure supplies.

  • Patent number: 5383437
    Abstract: An on-board diagnostic system for an evaporative emission control system of an internal combustion engine powered vehicle employs a positive displacement reciprocating pump to create in evaporative emission space a pressure that differs significantly from ambient atmospheric pressure. The pump is powered by using engine intake manifold vacuum to force an intake stroke during which both an internal spring is increasingly compressed and a charge of ambient atmospheric air is created in an air pumping chamber space. Vacuum is then removed, and the spring relaxes to force a compression stroke wherein a portion of the air charge is forced into the evaporative emission space. The rate at which the pump reciprocates to alternately execute intake and compression strokes indicates the pressure and flow through a leak in the evaporative emission space. Detection of this rate serves as a measurement of leakage for the purpose of distinguishing integrity of the evaporative emission space from non-integrity.

  • Patent number: 5297857
    Abstract: A system and method of controlling pressure in a wheel brake cylinder of a brake. The hydraulic cylinder is connected to an electrically driven pump and a flow control valve is connected between the pump and the wheel cylinder. The system and method operate to control the speed of a motor driven pump to generate a desired pressure in a cylinder of the brake; generate a differential pressure, in the flow control valve, proportional to pump flow and communication same to a spring biased valving element; cause the valving element to move, in response to pressure forces acting on the valving element, generated by the pressure differential, and the force of the bias spring, so as to selectively open and close an associated exhaust port, connected to a drain or sump, such that in the steady state an equilibrium condition is achieved where the pressure forces balance the spring force and the pressure in the hydraulic cylinder is constant.
