IPC: B30B9/24
Filed: 1987-03-21
Abstract: A method of dewatering filter cake in which the cake is supported on a positively driven pervious conveyor belt or filter cloth. The cake is guided about the circumference of a drum, with the drum positively driven at a variable speed of rotation. In the region of the drum, the pervious conveyor belt or filter cloth holds the cake against the periphery of the drum and additional pressing rollers press the filter cloth and cake against the drum. The drum drives the filter cloth in this region through the medium of the filter cake and induces shear effects in the cake. The speed of rotation of the drum is regulated in dependence on the tension existing in the filter cloth.

Patent DE-3721368-A1 (DE)
Title: Electric quartz (crystal-controlled) clock
Inventor: DEUSCH HELMUT
IPC: G04D7/00
Filed: 1987-06-29
Abstract: The invention relates to electric quartz clocks having an electromagnetic stepping motor which advances the dial train (motion work). In the manufacture of these quartz clocks, there is a need for a final test during which the quartz clocks have up to now been subjected to continuous operation over more than 12 hours. It is possible by means of the invention to replace this continuous operation by a quick test in which the clock hands are likewise adjusted over more than 12 hours, but can be accomplished in a substantially shorter period of time. This is achieved by means of switching over the electromagnetic stepping motor to a pulse train of increased stepping frequency. In accordance with the invention, the criteria which trip the switchover of the electromagnetic stepping motor are conveyed to the quartz clock via the battery contact springs. These criteria consist in permanent or temporary deviations of the feed voltage applied from a standard value.

Title: Control circuit for setting predetermined resistance values and resistance value ratios in photoresistors (photoconductors, photoconductive cells)
Inventor: BIDOVSKY ENGEL LUDWIG DIPL ING
IPC: H03G1/00
Filed: 1987-08-27
Abstract: The invention serves to set photoresistance values exactly. The resistance value is determined either by external circuit elements of the control circuit or by an electrical reference variable. As a result, it is possible to simulate by means of photoresistors a potentiometer which works in a potential-free manner and whose total resistance value is determined by a reference resistance of the same magnitude and whose part resistance ratio is determined by a reference voltage independently of the total resistance value. The photoresistance value is set by means of a filament lamp. The control is made possible by matching the controlled system. The matching is performed by a delogarithmising and inverting of the controlled system, as well as the displacement of the filament lamp voltage by a residual value, so that the light emission of the filament lamp cannot drop below a minimum.

Title: Electro-hydraulic control
Inventor: GIERER GEORG
IPC: F16H61/12
Filed: 1987-09-04
Abstract: Electro-hydraulic control for an automatic transmission (1) with two transmission input shafts (11, 12), the first (11) being connected to the turbine (181) of a hydrodynamic unit (18) and the second (12) directly to the output shaft (21) of the engine (2). The drive power is introduced singly as a function of the gear or also with torque division into the reduced planetary transmission (14). The automatic transmission can be adjusted by means of a selector slide (3), at least for the neutral position (N) and the forwards (D) and reverse travel (R). Solenoid valves (5), held in the zero position by spring force, are actuated by way of an electronic control module (4). A pressure medium source (6) supplies pressure and shift valves and dampers for operation of gear shift clutches and brakes (A to E). Between the pressure medium source (6) and the electronic pressure control valve (7) on the one side and the 4-3 switch-back valve (9), a safety valve (8) is also arranged which, in the event of failure of the electrical system, is switched under the action of an electronic pressure control valve (7), so that system pressure continues to be fed to the switch-back valve (9) and the spring chamber (111) of the tension valve (110) is vented. At the same time, the pressure in the line (112) to the clutch (A) is reduced to such an extent that there is no flow of power by way of this clutch. The electronic pressure control valve (7) in normal operation models the reduced control pressure and produces in the ... Original abstract incomplete. <IMAGE>
Patent DE-3730401-A1 (DE)
Title: Wind power installation
Inventor: SPINDLER ADOLF
IPC: F03D3/02
Filed: 1987-09-10
Abstract: The impeller wheels (stages) are arranged in different positions on a vertical, rotatable axle and fastened on the axle. The convexities (depressions) in the vanes are filled in the air flow, the pressure becoming greater or smaller depending on the wind force. This pressure brings about the rotation of the stages. As a result of the angle at the outermost edge of the vane, the greatest force is generated there. That is the new impulse for the drive, over and over again. The semicircular rear of the vane, with the angle, favours the return flow considerably. As a result of the free space between the axle and the vane, no stresses result. Conclusion: even in the case of an air draught (1 m per second), the axle with the stages rotates slowly and uniformly in a circle, supported by the spring mass in the lower part.

Title: Length measuring method
Inventor: SCHLOSSER GERHARD DR ING
IPC: G01B11/02
Filed: 1987-11-24
Abstract: The invention relates to a length measuring method in which an absolute scale is imaged section by section on a line sensor, the sensor signals are digitised and analysed in a microcomputer. The invention is characterised by the fact that a scale coded as light/dark sequence is used, the section of which imaged on the line sensor always contains at least two fields, one with the length 1l and one with the length kxl, in each case measured in the measuring direction, the length 1l is the greatest or the smallest length of the light/dark fields of the scale, and both the absolute and the fine position of the absolute scale are determined from the correlation of the light/dark transitions with the line sensor. The method is particularly applicable for automatic levelling, precision levelling and for range finding with unequal target distances of about 5 to 50 m, and can be used for positioning parts or in coordinate measuring. <IMAGE>

Title: Method for utilising the tidal lifting for energy generation and power station for carrying out the method
Inventor: LABENTZ PETER
IPC: F03B13/26
Filed: 1988-04-06
Abstract: The invention relates to a method for utilising the tidal lifting for energy generation and a power station for carrying out the method. In a repetitive manner, at least two displacing pistons are simultaneously moved between an upper and a lower position by means of the tidal lifting. The displacing pistons act on in each case one pressure piston via a hydraulic fluid. The pressure pistons form in each case one variable-volume compression space. A highly compressed gas is located between the pressure pistons. When the position of the displacing pistons is altered, the volume of the one compression space is reduced and the volume of the other compression space is increased. The gas which is being compressed is pressed through a flat gap betwen a pressure dish and a pressure plate and is heated by friction in the process. The gas then flows through a heat exchanger and gives off the heat energy taken up as a result of friction.
