Patent DE-3107809-A1 (DE)
Title: Apparatus for holding and releasing the draw-string of the draw-string closure of a laundry transporting bag in a transport device
Inventor: KREINBERG MANFRED
IPC: D06F95/00
Filed: 1981-02-28
Abstract: The apparatus is used in industrial laundries for opening and closing the draw-string closure of the lower aperture of tubular laundry transporting bags. The apparatus is arranged on the suspension gear (13) and the suspension gear running rail (14) of the transport device. The apparatus permits mechanical opening and closing of the draw-string closure (11) by an arrangement whereby a device (23) is provided for the clamping retention of the draw-string (12) and devices (24, 25) are provided to release this clamping. The device (23) for the clamping retention of the draw-string (12) has a linear guide and deflection rollers for guiding the said draw-string and a pressure roller mounted on one end of a two-armed lever and capable of being pressed into the linear guide, and also a leaf spring which holds the two-armed lever in the clamping position. The devices (24, 25) for releasing the clamping have working cylinders on whose piston rods (43 and 46) pressure pieces and/or deflection rollers are arranged. In order to open the draw-string closure, the piston rod (43) is pressed by means of the pressure piece (44) onto the free end of the two-armed lever. In order to close the draw-string closure, the piston rod (46) with the deflection roller in the region of the mounting for the end of the draw-string is pressed onto the part of the draw-string (12) located there, with the consequence that the clamping of the draw-string (12) in the linear guide is released, which moves the draw-string (12) in the direction of the arrow (54) and closes the draw-string closure. <IMAGE>

Title: Method for timing error correction and circuit arrangement for carrying out this method
Inventor: OBREMSKI MICHAEL
IPC: H04N5/95
Filed: 1981-03-26
Abstract: A method for timing error correction in video signals is described in which the line pulses are obtained from the video signal by means of an amplitude filter (11) and time filter (12). To ensure reliable operation even with relatively high short-time timebase deviations and during rewinding operation, two narrow control pulses following one another in time are obtained from an edge of the line pulses obtained, which control pulses are used for controlling the charging and discharging process of a discharge capacitor (18) and for forwarding the residual charge of this discharge capacitor (18) to a holding capacitor (24), the respective voltage of which is supplied as actual value to a control system with predetermined nominal value.   <IMAGE>

Title: Tightening pump unit
Inventor: FEULNER JOSEF
IPC: F15B21/08
Filed: 1981-09-12
Abstract: The invention relates to a tightening pump unit in which specified pressures are to be run. As a function of pressure switches which are allocated to the respective pressure, a directional control valve is operated which opens a bypass via which fluid can flow off from the line network. The pump unit is set for interval operation and is designed for small capacities. Non-return valves ensure that the pressure is maintained in the tightening cylinder. A selector switch enables the pressure switch corresponding to the pressure to be allocated quickly and without problem.

Patent DE-3145783-A1 (DE)
Inventor: ZETTNER MICHAEL
IPC: F01C1/356
Filed: 1981-11-19
Abstract: A rotary engine comprises a circular rotor surrounded by an annular stator. The rotor is provided around its outer circumference with spaced combustion chambers and with recesses therebetween. Each recess serves as an expansion chamber for a jet of gas produced by combustion in an associated combustion chamber. Each recess is also provided, remote from the associated combustion chamber, with a cam. The stator at its inner circumference has retractible reaction members which are movable into the recesses to be acted on by the gas jet so as to create forces acting in opposite sense on the rotor and stator and thus cause the rotor to rotate. The reaction members have deflector surfaces arranged to deflect the gas jet in such a manner that the members are drawn into the recesses, the members being engaged by the cams during the rotor rotation and moved back into the stator.

Title: Device for cleaning and classifying cereal, seeds or the like
Inventor: HAPPLE KARL DIPL ING
IPC: B07B9/00
Filed: 1982-05-18
Abstract: In a device for cleaning and classifying cereals, seeds or the like in which a main fraction is divided into two substreams, a first substream, which essentially contains only useful material and a second substream which, in addition to useful material, also contains weaker material, both substreams are subjected to Schrollen sifting and then cleaning in different classification and cleaning sieves. In this process, the Schrollen sieves are arranged one on top of the other and partially overlapping one another. A further fraction is fed into an expansion space; the useful material contained in this fraction then drops out of the expansion space onto a third Schrollen sieve to which a further classification sieve is assigned. This third Schrollen sieve and the associated classification sieve located below it are also arranged, at least partially overlapping one another, above the first and second Schrollen sieve. In this way, performance is improved without the basic outline of the machine having to be increased substantially, only a somewhat greater constructional height having to be accepted, space for which is however, in any case frequently available at the respective installation site.

Title: Bridge circuit
Inventor: KUEHN WILLI
IPC: H03K17/695
Filed: 1982-09-04
Abstract: A bridge circuit is proposed which consists of four power field-effect transistors for controlling a load (14) in the lateral branch of the bridge, all four power field-effect transistors (10 to 13) being of the same conductance type (n-channel or p-channel). Each of the gates is connected via separate resistors to at least one supply-voltage source. In this case, the gates of the power field-effect transistors of one bridge diagonal (10, 13 or 11, 12 respectively) can in each case be driven together, switching means (18, 20) being provided by means of which a zero potential can be preset. In this way, the bridge circuit can advantageously be controlled directly via comparator outputs, resulting in small voltage surges and radiated-interference problems, as well as a simple layout design. <IMAGE>

Inventor: SINEPOLSKIJ VLADIMIR ST
IPC: B03B5/24
Filed: 1982-10-07
Abstract: The invention relates to the field of enriching useful mineral materials. The essence of the method of controlling the pulsating flow of separating liquid in hydraulic jigs in which the control action is based on altering the volume of the compressed air which is cyclically fed to the hydraulic jig and produces the pulsating movement is that the control action is produced in accordance with the velocity of the vertical movement of the separating liquid in the hydraulic jig. The device for carrying out the method comprises a detector (10) whose sensor is a float (11) which moves up and down together with the separating liquid and responds to the changes in intensity of the pulsating movement, a transducer (12) connected in series with the detector (11) and a series circuit consisting of a comparison network (14) which is also coupled to a set point device (15), a controller (16), a control unit (17) and a setting mechanism (18) incorporating a gate valve (6) which regulates the compressed-air supply. According to the invention, the detector (10) is a velocity detector for the vertical movement of the separating liquid, and a peak-value detector (13) with an averaging network is connected in series between the transducer (12) and the comparison network (14). The invention can be used advantageously in automating gravity grading processes in coal-preparation plants. <IMAGE>
