A voltage regulator includes a transformer, a plurality of output stages and at least one switch. The transformer has a primary side and a secondary side, and the switch(es) are coupled to the primary side of the transformer to open and close to transfer energy to the transformer. The output stages are coupled to the secondary side of the transformer to receive energy from the transformer and provide output voltages. The output stages prevent current from flowing through the switch(es) during ti...

A stem regulator for direct mounting on the valve of a high pressure gas cylinder to provide a reduced delivery pressure for components or circuits of lesser pressure rating. The main body of the regulator, which contains its working parts, is adapted to serve, for example, as an inlet nipple for connecting the cylinder valve to a conventional adjustable pressure regulator. At one end, the body has a cylinder valve coupling face and nut and at the opposite end has an adaptor threaded to mate wit...

A voltage supply circuit provides a desired regulated voltage at an output utilizing a PNP and an NPN current mirror arranged to oppose one another. The NPN current mirror includes a pair of transistors operated at different current densities which produce a delta V.sub.BE voltage that is used to produce a reference current. The reference current is used to derive the regulated voltage which is a function of two independent resistor ratios.

A pressure control assembly is disclosed. The assembly includes a pressure transducer for detecting upstream pressure. A diaphragm is used to regulate flow through the assembly, and is forced into a closed position by pressure from a fluid column. The pressure on the fluid column is controlled by a piston driven by a step motor. The step motor is activated in response to signals from the pressure transducer.

A pressure regulator for independent automobile heater fuel lines, particularly for connection upstream of a dosing pump. The pressure regulator includes an upper housing portion, and a lower housing portion which are connected together with a diaphragm being disposed between the upper housing portion and the lower housing portion. The diaphragm operates with the upper housing portion to form an air space and cooperates with the lower housing portion to define a pressure regulation space. An adj...

A voltage regulator that reduces the voltage output of a generator to make it appropriate for use with an external load. The voltage regulator includes a starting unit for use with on-demand generators to cause the on-demand generator to start without presenting a risk to the external load.

A switching regulator for use with various kinds of electric and electronic equipment as a DC stabilizing power source. The switching regulator has a switching element implemented as an n-p-n switching transistor, an overcurrent detecting circuit for detecting an overcurrent ascribable to a fault, and a start delaying circuit for, after the switching transistor has been caused into an inactive state, feeding to the transistor a starting current which is delayed by a predetermined period of time....

A window regulator device has an endless wire connected to a glass and a regulator handle and disposed in a space between an outer panel of a door and a glass receiving space formed in the door. A part of the wire is extended into a space between an inner panel and the glass receiving space over a sash and engaged with the handle operating member, so that the glass is raised by the handle.

A key for operating a regulator-flow meter assembly used with medical gas cylinders. The regulator-flow meter assembly includes a main valve having a flat stem and a rotatable yoke. The key comprises an elongated metal block having a first elongated opening adapted to fit over the main valve stem. The elongated opening is disposed at an angle to the axis of the block and is located adjacent to one end of the block. The block also includes a second opening of circular cross-section adapted to fit...

An air guide tube 62 is mounted within a tubular portion 42 formed in a housing 13 of a regulator 1 for diving. One end of the tube 62 is formed with a valve seal 63A against which a valve 72 is pressed and another end opposite to this end is formed on its inner surface with threads 67.
