A window regulator comprising a vertically extending support member having respectively on upper and lower ends thereof turn up guide members, a drive cable extending between the two turn up guide members and being connected to a movable driven member such as a bracket connected to a window glass, and a drive mechanism for moving the drive cable. One of the turn up guide members is movably supported on the support member such that the distance between the turn up guide members can be changed, an...

An intermittent regulator is provided in which the regulator alternates between supplying partial vacuum to a patient for withdrawing fluids from the body of a patient, and supplying atmosphere to a patient, at a selected intermittent rate, that is adjustable upon adjusting a timing mechanism. The timing mechanism is isolated from communicating with the vacuum being drawn from a patient, separating the regulator into a "wet" side and a "dry" side. The regulator includes a piston and spool, each ...

A regulator for regulating outlet pressure of a fluid supplied to the regulator from a fluid source includes a body having an inlet, and a pressure regulating chamber disposed in the body. A high pressure fluid circuit extends between the inlet and the pressure regulating chamber for transmitting the fluid from the inlet to the pressure regulating chamber. The high pressure fluid circuit includes at least two longitudinally extending high pressure passages in fluid communication with each other....

A mobile ballast plow comprises a machine frame and a ballast planing plow vertically adjustably mounted on the machine frame and extending from shoulder to shoulder. The ballast planing plow includes central plow elements extending over the center track portion, and a ballast conveying device associated with the central plow elements and arranged in the center track portion. The ballast conveying device consists of at least one vertically adjustable broom rotatable about an axis extending in th...

A dust cover is provided with a transverse hook such that when the dust cover is secured in place on the first stage of a scuba regulator, the regulator assembly can be handled and hung by the hook without damage to the regulator or damage or kinking of regulator hoses. Embodiments for both American and European (DIN) configured regulators are enclosed.

The brake regulator controlled by the load of a vehicle uses a fluidic mechanism which acts on a first piston (7) capable of translatory movement in a bore formed in the body (1) of the regulator, the first piston (7) being provided with a push rod (33) capable of cooperating with one end of a second piston (21) forming part of a valve which is open in the rest position. Mechanisms (31,37) are provided for maintaining, at rest, a given distance between the end of the second piston (21) and the p...

A pressure regulator includes a flexible diaphragm which sets-off a liquid chamber having an inlet and an outlet for respectively introducing liquid into and discharging liquid from the liquid chamber under the control of an associated valve through an actuator operated by the movement of the diaphragm. The valve is carried by a coupling which is connected to the housing inlet which, upon the uncoupling of the coupling, allows inspection and/or repair of an associated valve seat or the actuator ...

A voltage regulator that establishes a bandgap voltage reference and achieves output voltage regulation with a single feedback loop. The bandgap voltage reference is established by equal current flow through each of two branches of a proportional to absolute temperature current mirror. The equal current flow through the two branches of the proportional to absolute temperature current mirror is achieved by the feedback loop controlling the current flow in response to the bandgap voltage reference...
