A window regulator for a motor vehicle is provided. The window regulator is arranged to provide a controlled movement of a window pane between a raised position and a lowered position, the window pane being guided on two opposite edges by guide means. The window regulator comprises a lifting arm slidingly connected to the window pane at one end and pivotable about a point near its other end, means to produce rotation of the lifting arm about the point to produce said controlled movement of the w...

A current regulator for a laser tube used in a ring laser gyroscope includes a ballast resistor coupled to the laser tube's anode, an output for the current, such as a current sensing resistor, a current source coupled between the ballast resistor and the output, a control circuit that establishes the amount of current flow through the current regulator, and a voltage divider that senses the voltage across the current source. The current source includes two transistors coupled in series and the ...

A regulator including a movably, preferably hingedly, mounted member having a distal face, exposed to a reference pressure, and a frontal face, exposed to fluid passing through the regulator. Attached to the member is a structure that variably impedes fluid flowing through the regulator. The amount that this structure impedes the fluid flow varies as a function of the difference between the pressure of fluid on the frontal face of the member and the reference pressure. The impeder may be an inte...

A switching regulator composed of a push-pull converter with a buck or boost regulator connected upstream. The output inductance of the regulator is split into two separate inductances each of which is fed to one leg of the push-pull circuit. The push-pull converter is expanded to a resonance converter by means of resonance capacitors. This switching regulator has a high efficiency and is particularly suitable for use in satellite power supplies.

A pressure regulator in the form of a proportional pressure control solenoid provides predictable and repeatable control of pressure in response to an electrical input signal. The pressure regulator converts the electrical control signal to an output pressure at the load independent of the flow requirements. The electromagnetic portion of the pressure regulator generates a force proportional to the average current supplied by a controller and applies that force to the hydraulic components of the...

In the present invention, an amplitude of a triangular wave from a triangular wave generating circuit is controlled depending on a power source voltage and further the current value for charging and discharging a capacitor is also controlled depending on the amplitude in such a manner that when the power source voltage drops the frequency of the triangular wave to be outputted is maintained at a predetermined frequency by reducing the current value and the amplitude and the waveform gradient is ...

A linear voltage regulator generates a regulated output voltage from a low overhead input voltage. The voltage regulator includes a series pass device that generates the output voltage based on a control signal. A sense circuit generates a sense signal that is proportional to the output voltage. An integrator generates an integrated signal based on a difference between a first voltage reference and the sense signal. The integrated signal includes a first voltage reference component and a sense s...

The regulator of this invention is used specifically to regulate the idling speed of an internal combustion engine and includes a servomotor, a throttle unit and a holder designed as separate units and are intended to be combined in an appropriate manner for a particular application. Thus, the throttle unit is provided with a throttle housing incorporating in a cylindrical housing part, a turning space for a throttle member which is connected to a flow channel via an inlet opening and an outlet ...

A diaphragm actuated pressure regulator is provided having a molded contoured diaphragm capable of operation in the upper portion of the diaphragm's deflection stroke without experiencing material deformation and thereby preserving the precision of the diaphragm's response to pressure fluctuations. The pressure regulator includes a curved lever arm for transmitting the deflection of the diaphragm to a displacement of a valve pad which regulates the flow of gas from an inlet through an orifice re...

A gas regulator, relating in particular to a regulator for a gas or air cylinders, for supplying compressed air to a paintball gun or other compressed air powered projectile firing devices. A micro controller operably associated with the gas regulator is adapted to generate a shots remaining signal by receiving a pressure drop signal from a pressure transducer and a set of shot fired signals corresponding to the gas pressure drop signal. A method is also provided for generating the shots remaini...
