Adjusting device for an optical element

Abstract: The support (23) of the optical element (17) is connected by means of a bellows (15) to a basic body (10) which has a reference surface (22), and can be adjusted with respect to said basic body. As adjusting elements there are provided between the support (23) and the basic body (10) two annular discs (1, 2) which are clamped by the spring force of the bellows (15) and rest against each other with wedge surface (3, 4) and can be rotated with respect to each other, and which make it possible to adjust the optical element in a simple, precise, and permanent manner. The device is suitable for adjusting a reflecting mirror in laser cavities (laser resonant cavities).

Attitude insensitive gas generator

Abstract: A GENERATOR HOUSING IS FORMED WITH ONE OR MORE BELLOWS SECTIONS SO THAT A LIQUID REACTANT IS CONFINED WITHIN THE HOUSING BY THE BELLOWS REGARDLESS OF THE ANGULAR ORIENTATION OF THE GENERATOR. A SOLID BODY PROVIDING A REACTION SURFACE IS CENTRALLY MOUNTED WITHIN THE ENCLOSURE. UPON CONTACT OF THE LIQUID REACTANT WITH THE SOLID BODY A GAS IS GENERATED, BUT CONTACT IS DESTROYED BY EXPANSION OF THE BELLOWS. A PLURALITY OF GAS OUTLETS ARE PROVIDED WITHIN THE HOUSING SO THAT IF ONE IS SUBMERGED BY LIQUID REACTANT, THE REMAINING OUTLET WILL REMAIN EXPOSED FOR THE EDUCTION OF GAS.

Single sheet feeding mechanism

Abstract: Single sheet feed reliability for suction cup mechanisms handling highly permeable paper sheet is improved with a quickly and conveniently attached rigid cup enclosure of an extensible bellows cup. An internal thread is provided in the suction pipe ends for receipt of an externally threaded T-nut shank. The T-nut secures both, the rigid cup enclosure and the extensible bellows.

Hydraulically damping rubber bearing engine mount

Abstract: The invention relates to a hydraulically damping rubber bearing engine mount for motor vehicles, having two end walls lying opposite one another in the axial direction and two chambers which are designed as a pressure and an auxiliary chamber and which contain a damping fluid and are connected to one another by a restricted orifice. An annular, rubber-elastic spring element adjoins the pressure chamber and is secured on an end wall. A compensating chamber adjoins the auxiliary chamber and is separated from the latter by a bellows. The damping characteristics of the rubber bearing are alterable by intervention from outside. In order to be able to alter the damping effect of the rubber bearing continuously right up to complete cancellation, a diaphragm is clamped fluid-tightly in the pressure chamber and is loaded on the one side by the damping fluid and on the other side by compressed air which can be fed in from outside. When the diaphragm is loaded by compressed air, an air chamber is formed between the diaphragm and the spring element with the diaphragm lifting off partially or completely from the spring element in response to the amount of compressed air fed from the outside in accordance with a control signal proportional to the desired vibrational characteristics of the vehicle.

Bathtub assembly for handicapped persons

Abstract: A bathtub assembly that can be raised and lowered has a bottom and a lift plate with scissors-like guide frames positioned between them, which said frames guide the lift plate vertically. Two collapsible hoses or bellows, made of material that bends but does not stretch, are sealed at the ends, one end being attached to the lift plate and the other to the bottom. The hoses or bellows 20, are connected by means of connection hoses and a manual valve to the house water supply line.
