Patent DE-3139873-A1 (DE)
Title: Machine for the edge grinding and facetting of optical lenses
Inventor: JURANEK HANS-JOACHIM DIPL PHYS
IPC: B24B9/14
Filed: 1981-10-07
Abstract: In centring machines, whose centring spindles arranged in alignment are each driven from a one-piece shaft via a gear drive, a certain asynchronism in the revolving behaviour of the spindle can occur through positive or negative accumulative tolerances in the respective gear train due to slight deviations in the tooth pitch or deviations from the desired value of the tooth-flank dimensions. The rotary-angle displacements occurring as a result in the clamping bells holding the workpiece under clamping pressure can certainly cancel each other out again in the course of a complete revolution of the drive shaft. However, the chafing points on the surface or surfaces of the finish-machined workpiece only inserted in the clamping bell of the machine for edge grinding and/or facetting, which chafing points are caused by the relative movement of the clamping bells, cannot be undone. In order to avoid this, it is proposed that the shaft serving to drive the two centring spindles be of two-piece construction, and that a device for balancing different torque loads in the gear train of the respective centring spindle be arranged between the two shaft parts.

Title: Torque detector device
Inventor: AOSHIMA SHOZO
IPC: G01L3/12
Filed: 1981-10-27
Abstract: A description is given of a device for determining the torque transmitted between two rotating elements. An input element and an output element are connected via a transmission device which permits a relative angular misalignment between the elements. Attached to one of the two rotating elements is a wheel disc which has a number of signal components arranged on a circle. A detector for detecting the signal components is arranged on a frame opposite the wheel disc. A sealing washer with a sealing part for partially covering the signal components is attached to the other rotating element in a position opposite to the wheel disc. The number of signal components detected by the detector is altered in accordance with the relative angular deflection between the input element and the output element while these are in rotation; the torque between the two rotating elements can be determined numerically by means of the number detected. <IMAGE>

Patent DE-3245570-A1 (DE)
Title: Bipolar coagulation instrument
Inventor: SUTTER HERMANN
IPC: A61B18/14
Filed: 1982-12-09
Abstract: A bipolar coagulation instrument has, embedded in a holder, two parallel electrodes which are secured in the holder against rotation and against longitudinal displacements. At the working tips the electrodes are bent so that these tips can be easily seen by the operator despite the holder situated behind them. When a pressure is exerted on the instrument both in the longitudinal direction of the electrodes and in the direction of rotation, these bends result in forces which are absorbed by the abovementioned anchoring. A design for a micro-instrument is also possible with the aid of an extension.
Patent DE-3308102-A1 (DE)
Title: Spreader for artificial fertilizers or similar granular or powdered substances
Inventor: DIEDRICH FRITZ
IPC: A01C17/00
Filed: 1983-03-08
Abstract: A spreader for artificial fertilizers or the like has a funnel-shaped storage container provided with outlet apertures in the bottom area and at least one distributing plate arranged below this container and rotating about a vertical axis. The outlet apertures are each individually or jointly closable by means of a quantity slide which can be operated by a control lever; the distributing plate is driven by means of a hydraulic motor. In the line feeding the pressure medium delivered by a hydraulic pump to the hydraulic motor a flow regulating valve is provided which feeds a predetermined, constant partial quantity of the pressure medium flow to the hydraulic motor, thereby making possible a preselected constant speed of rotation of the distributing plate until the flow of pressure medium falls below a specific minimum quantity. The excess or residual quantity of pressure medium flowing out of the flow regulating valve by way of a return line is led by way of an adjustable pressure control valve to a single-acting lift cylinder, which in turn operates the control lever for the quantity slide(s) against the force of a return spring. Altogether, this hydraulic coupling of distributing plate drive and control lever movement facilitates a simple single-lever actuation of both movements which precludes incorrect operation.

Title: Arrangement for automatic receiver-end correction of an incorrectly recovered carrier phase
Inventor: BESSAI HORST DIPL ING
IPC: H04L27/38
Filed: 1983-10-25
Abstract: The invention is intended to lock quadrature-amplitude modulation receivers for e.g. 16-QAM via a phase-locked loop back onto the reference carrier phase in the event of an incorrectly recovered carrier phase, with no need for differential coding nor a different transmission-end procedure to mark the reference phase. For this purpose, a pulse generator 5 is provided according to the invention which is started up by an alarm signal which is derived from the synchronisation failure of the data receiver 6 and whose pulse voltage is superimposed on the phase-lock voltage at the input of the voltage-controlled oscillator 2 in such a way that locking onto a different carrier phase condition of the voltage-controlled oscillator, which repeats itself until the alarm signal subsides, i.e. until the provided reference carrier phase is attained, shuts off the pulse generator 5. The pulse generator is preferably designed as an astable multivibrator 51, 52, whose pulse repetition frequency f = 1/(2RC.In3) is selected by corresponding dimensioning of its frequency-defining components 53, 54 in such a way that it becomes shorter than the response time of the data receiver 6 (Fig. 1). <IMAGE>
Patent DE-3338781-A1 (DE)
Inventor: KEDZIERSKI HEINRICH DR
IPC: F15B15/26
Filed: 1983-10-26
Abstract: A fluid-pressure-operated, double-acting working cylinder which dampens the final braking of the work piston, includes a cylinder housing with a movable work piston disposed therein, the work piston dividing the cylinder into two work chambers. A piston rod, on which the work piston is mounted, extends through the housing. At least one auxiliary braking member is disposed on at least one side of the work piston in an offset slidable relation to the work piston. A braking arrangement disposed on the auxiliary braking member is controlled by fluid pressure to brake the auxiliary braking member to a desired position within the cylinder. A dampening chamber, a dampening spring configuration is disposed between the auxiliary braking member work piston such that, following braking of the auxiliary braking member, continued movement of the work piston is effectively dampened. An auxiliary check valve formed in the auxiliary braking member allows communication of fluid pressure between the dampening chamber and the auxiliary braking arrangement to increase the effective braking of the auxiliary braking member. A throttle is disposed on the auxiliary braking member to allow communication of the fluid pressure in the dampening chamber to the work chamber into which the work piston is moving. A check valve is disposed between the pressurized work chamber and the dampening chamber to allow fluid pressure introduced to the pressurized work chamber to flow into the dampening chamber thereby pressurizing the dampening chamber as well.

Title: Device for actuating a closing means actuated by a pressure medium
Inventor: WEILER WALTER
IPC: E03F7/02
Filed: 1984-01-11
Abstract: A closing means (3) which can be actuated by applying a pressure medium, for example a backwash seal, designed as a hose valve or a diaphragm valve, in a waste water line (1), a drain or the like, has assigned to it an actuating device which comprises a reservoir (9), a connecting line (15) and a pump (21) and which forms a closed pressure medium system; the pressure medium, after each closing operation, is forcibly returned to the reservoir by the pump and during the closing operation is delivered to the closing means either by the pressure, which the pump generated during the earlier back-pumping process and which was stored by a gas cushion, or by the direct pumping action of the pump. It is no longer necessary to supply fresh pressure medium and to drain spent pressure medium before and after each closing operation, respectively. <IMAGE>
