Patent DE-3623455-A1 (DE)
Title: Optical sight
Inventor: EHLI LUDWIG
IPC: F41G3/32
Filed: 1986-07-11
Abstract: In the case of aiming optics, a device for checking the adjustment and the harmonisation relationships between the line of sight and the barrel bore axis of a tube weapon (weapon with a barrel) consists of an optical radiating device which is mounted on the barrel muzzle and by means of which a marking which represents the barrel muzzle of the tube weapon can be reflected into the beam path of the aiming optics. In order to ensure that the optical radiating device is mounted such that it is free of changes and to make possible simultaneous checking of the adjustment position and the harmonisation relationships of a plurality of aiming apparatuses, the optical radiation source is constructed as a quasi-point radiation source of high light intensity. <IMAGE>

Title: Holding pliers
Inventor: FRUEH HEINRICH
IPC: B25B7/12
Filed: 1986-09-05
Abstract: The holding pliers are used to firmly hold the fastening part of a studded boot (12) in order to prevent the fastening part being torn out of the boot sole (14) when the stud (11) is turned for the purpose of loosening and exchanging it. The region of the boot sole (14) surrounding the stud (11) is supported by one holding leg (19), whereas the other holding leg (17) is applied by a driving member (28) to the fastening part in the interior of the boot and firmly holds said fastening part so as to be fixed in terms of rotation. In this way, the torque of the stud is not transmitted to the boot sole and destruction of the boot sole owing to high torques is avoided. <IMAGE>

Title: Gas and liquid bearing for rotary motion, version I/II
Inventor: WITTEMANN HANS-JOACHIM
IPC: G02B26/12
Filed: 1986-11-20
Abstract: It is possible to achieve a highly accurate rotary bearing with simple means using easily produced components of the gas and liquid bearing. The rotating part consists of a spherical segment of two bases. The stationary part consists of a spherical cap matched to the above spherical segment and of an annular disc which assumes the task of axial support. By forcing gas or liquid into the spherical zone (radial-axial support) and the annular plane bearing arrangement (counter-axial support), a gas or liquid film is formed between the stationary and rotating part. By relocating the feed passages for the bearing medium, it is possible to use the stator described above as a rotating part (rotor). By appropriate dimensioning, it is possible to employ the gas and liquid bearing for a range of applications from machine construction to precision engineering and metrology.

IPC: H05B41/392
Filed: 1987-08-13
Abstract: The invention relates to a circuit arrangement for adjusting the brightness (dimmer) of lamps (8) having a control circuit for the phase of the supply voltage for limiting the current fed to the lamps (8). So that the brightness of so-called energy-saving lamps, in particular when used simultaneously with conventional filament lamps, can also be adjusted, it is proposed according to the invention that the control circuit (6) for the phase of the supply voltage limit the amplitude of the supply voltage symmetrically to their (its) maximum values as a function of the desired brightness. By means of such a dimmer, the brightness of energy-saving lamps and filament lamps present in an illumination system are controlled in approximately the same manner. <IMAGE>

Title: Membrane oscillator (diaphragm oscillator) having a piezoelectric drive
Inventor: STEIN DIETER DIPL PHYS
IPC: H04M1/03
Filed: 1987-09-07
Abstract: In the case of membrane oscillators having a piezoelectric drive, a connection (A) in the form of a strip or wire must make contact with an electrode (E1) which is applied in the form of a layer on piezo ceramic (Pk). The new membrane oscillator is intended to take account of the increasingly more stringent requirements for the adhesive strength and the life of the means of making contact. The connection (A) is made contact with on a raised contact surface (Kf) which is arranged in the region of the node line (K1) of the oscillation, is preferably of annular shape and is constructed as local reinforcement of the electrode (E1). In addition to extending the life, the positioning of the connections (A) is simplified as a result of the contact surface (Kf) being able to be raised. The membrane oscillator is suitable for telephone membranes or piezo actuators of ink-mosaic printers (dot-matrix printers). <IMAGE>

Title: Pallet with feet
Inventor: KNOESS HANS-JUERGEN
IPC: B65D19/00
Filed: 1987-12-07
Abstract: A pallet with feet is described, holes being formed in the bearing plate of the pallet next to each of the feet in such a way that a second pallet of identical construction can be placed selectively with its feet on the feet of the pallet located below it or, after turning it, in the holes. In the case of pallets being placed one above the other, the continuous feet thus conduct the weight away such that each pallet only has to bear its own weight and the weight of the articles located on it. If the empty pallets are to be transported in a stacked manner, the pallets are fitted into one another in the manner described so that they take up a noticeably reduced stacking height.

IPC: B01D47/08
Filed: 1988-02-22
Abstract: A device for purification of gas by means of a liquid contains a chamber (14), into which the gas to be purified flows and into which the liquid is transported. A transporting unit (24) protrudes into the liquid and transports this directly to a spray unit (34) disposed above, from which the liquid then reaches the chamber (14). The device should be constructed to have the effect that for a low structural volume an intensive purification of the gas is made possible. It is proposed that the spray unit (34) is provided with outwardly directed channels (38), the length of which can be predetermined to achieve a build-up of pressure. These channels (38) are terminated by jets (40) located radially outwards, through which the liquid is sprayed under pressure into the chamber (14). <IMAGE>

Abstract: The isolating converter described comprises a pulse-width modulator (PWM) which emits two pulse-width modulating switching pulses (LA, LB). The switching pulses are shifted with respect to each other by one half period of an unmodulated pulse. The isolating converter furthermore comprises an output filter (C2, L1, C3). In order to reduce the spatial dimensions of the isolating means (U1, U2) of the converter as well as the expenditure on parts for the output filter (C2, L1, C3), provision is made to provide the isolating converter with two switching transistors (S1, S2) which are each controlled by one of the two switching pulses (LA, LB). Two transformers (U1, U2), whose primary winding (n1, m1) is mounted in series with the contact path of each of the two switching transistors (S1, S2) are charged with the power transmission of the loads connected to the converter. The two series circuits, each consisting of the secondary winding (n2, m2) of one of the transformers (U1, U2) and a diode (D2, D3), are connected in parallel to the input of the output filter (C2, L1, C3). <IMAGE>
