Patent DE-3317442-A1 (DE)
Title: Diaphragm air vessel
Inventor: NENNING PETER DR ING
IPC: F16L55/052
Filed: 1983-05-13
Abstract: A diaphragm air vessel is described, whose gas space pressure automatically follows the pressure in a high pressure vessel in such a way, that in order to compensate for pressure losses in the delivery line to the high pressure vessel the mean pressure in the air vessel is higher than in the high pressure vessel. The liquid is delivered thereto in pulsating flow. The excess pressure is caused by the interaction of several elements:   1. If the pressure in the air vessel is insufficient, the separating diaphragm in the air vessel, during the delivery stroke, hits defined stops, and its travel is correctly adjusted to the gas- filled buffer volume of the air vessel. 2. Said buffer volume is connected, via a weakly-sprung suction valve and a pretensioned discharge valve, with the gas volume of the high pressure vessel. 3. If, during the delivery stroke, the diaphragm of the air vessel hits the stop prematurely, the inertia of the liquid in the line to the high pressure vessel produces a reduced pressure on the pump side, which results in the gas volume in the air vessel being replenished via the said weakly pretensioned suction valve. After the procedure has been repeated one or more times, the gas volume in the air vessel has been replenished to such an extent, that during the delivery stroke the diaphragm, without hitting the stop, compresses the gas cushion to the required pressure, i.e. the pressure in the high pressure vessel plus the pressure loss in the supply line thereto.   If the pressure in the installation drops, a discharge takes place of the excess pressure in the gas volume of the... Original abstract incomplete.
Patent DE-3320090-A1 (DE)
Title: Displacement pump
Inventor: STREICHER MANFRED
IPC: F04C5/00
Filed: 1983-06-03
Abstract: The displacement pump (10) has a housing (11), which can be closed by a cover (22), with a cylindrical interior (17), at least a part of the circumferential wall (16.5) of which is of circular cylindrical design. Mounted rotatably centrally in relation to this circular cylindrical section (16.5) of the housing circumferential wall (16) is a rotor (12) with three rollers (29). Tensioned around the rollers (29) is a band-shaped or belt-shaped separating part (13) which on both sides extends in the axial direction as far as the end walls (23, 24) of the housing (11) and bears tightly against this. On the circular cylindrical section (16.5) of the housing circumferential wall, the rollers (29) press the separating part (13) against the housing circumferential wall (16.5). On the opposite side, the separating part (13) is connected flexibly but tightly to the housing circumferential wall (16). As a result, a number of space parts (17.1, 17.2) of the interior (17) of the housing (11) are separated off from one another by the separating part (13). As a result of the rotating movement of the rollers (29) relative to the non-rotating separating part (13), these space parts (17.1, 17.2) periodically change their shape and their size. As a result, a conveying effect is created for the medium being conveyed which is situated outside the separating part (13) in the interior (17) of the housing (11). The medium being conveyed, which is periodically sucked into the suction space (17.1), is conveyed across to the pressure space (17.2) and, as a result of the displacement effect of the rollers (29) and of the separating part (13), out of the latter ...

Patent DE-3327580-A1 (DE)
Title: Intruder detection device
Inventor: WINTER HORST FRIEDRICH
IPC: G08B13/04
Filed: 1983-07-30
Abstract: In an intruder detection device comprising a sound detector frequency-selectively responding to glass fracture and splintering wood, and an alarm device coupled thereto, an additional sound generator is used which, to obtain a response from the sound detector, emits suitable sound signals whenever a window or door element to be monitored is opened or correspondingly vibrated. As a result, the frequency-selectively responding sound detector can also be used when the intrusion itself does not lead to a glass fracture or splintering of wood. In this case, the sound waves specific for this are artificially generated by the sound generator. The latter, which can also operate electronically, at least partially, is preferably of purely mechanical construction. In the case of surveillance of an opening, a spring element of the sound generator can be tensioned by the movement of opening, in order to then impact against a vibration body, generating sound. A magnetic holding element which, during the opening of the window or door element, moves away from the vibration element on which the spring element is attached, can be used for tensioning the spring element.

Title: Arrangement for generating sine-wave voltages with different frequencies and amplitudes in a line simulation device of a telecommunications system, in particular a telephone PABX system
Inventor: BRAEMER HEINRICH DIPL ING
IPC: H04M3/32
Filed: 1983-09-22
Abstract: A timer which can be set by means of an address characterising the division factor of the required frequency or frequency combination, a clock frequency and a controller has a number of outputs which corresponds to the number of frequencies required for the sine-wave voltage to be generated. Square-wave voltages generated via these outputs are in each case supplied to a shift register which converts the supplied square-wave voltages and step voltages, the input frequency of the shift register being greater than the output frequency by a specific factor. The generated output voltages are fed as approximated sine-wave voltages via low-pass filters to a single input of an operational amplifier which adds these voltages and downstream of which a digital/analog converter is connected which can be controlled by means of addresses for selection of amplitude values. The amplitude-controlled output values of said converter are supplied to a further operational amplifier which switches the feedback in two values so that the identification to be generated for the line simulation device is applied to the output of the second operational amplifier. <IMAGE>

Title: Housing for a surface-mounted installation apparatus
Inventor: FASSBENDER GERHARD
IPC: H05K5/00
Filed: 1984-01-16
Abstract: In the case of the mounting of installation apparatuses on an uneven wall, firm mounting can, if at all, be achieved using conventional housings only by increased tightening of the mounting screws. However, particularly in the case of housings consisting of thermoplastic, this leads to undesirable deformation. The invention is based on a housing having two diagonally opposite mounting holes (3, 4) which are used for mounting on a wall by means of screws and are in each case surrounded by a spacer ring (13, 14) which is integrally formed on the housing (1) in the same material. In the region of at least one of the two other diagonally opposite corners of a rectangular base surface (2) of the housing (1), a supporting foot (5, 6) is arranged which overhangs the base surface (2) for at least the same width as the spacer rings (13, 14). At the same time, the supporting foot (5, 6) is constructed such that it is deformable and can thus compensate for different distances between the base surface (2) and the wall. <IMAGE>
