Title: Washing machine for small metal parts - has rotatable basket for parts slightly tilted to distribute components uniformly during washing
Inventor: WEININGER LOTHAR
IPC: B04B11/04
Filed: 1979-10-03
Abstract: Metal parts such as screws, nuts and rivets are washed or otherwise processed in a basket or portable vessel. This is mounted in a bowl or holder on a rotating machine. The holder can be tilted about a vertical axis as well as rotated around its own axis. The basket is inserted with the holder slightly tilted forward. Processing is carried out with the holder tilted backwards at an angle to the vertical. When processing is completed, rotation continues and the bowl is returned to the vertical. This ensures that the metal parts take up a uniform distribution in the basket which can then be removed and placed in a centrifuge. Centrifugation occurs without the problem of excessive vibration due to an unevenly distributed load.

Title: Semiconductor strip resistor photolithographic process - uses increased number of strips on slice to decrease resistor value tolerance variation
Inventor: HORL MANFRED DIPL ING
IPC: H01L27/08
Filed: 1979-12-21
Abstract: The photolithographic masking process is used to produce steep sided strip resistors in a semiconductor element and to maintain an accuracy of formation for high density units so that width deviations for 50 micro m wide strips are reduced so keeping resistance values within 1% of the intended value. The strips are end connected to form the complete resistor on the semi-conductor slice. Instead of exposing and doping, three resistive strips (10,11,12) (20,21,22 fig 3) on the slice five are exposed so that the edge diffusion and parallax for the three central slices (10,11,12) can be more closely controlled, at the photoresist lacquer edge, and be more accurately assessed. The flanking edge strips may be left unconnected or connected in circuit as required.

Title: Start=stop system for IC engine - has circuit putting start switch on standby only after ignition switch has closed and engine has attained given state
Inventor: PAGEL ERNST-OLAV DR ING DR
IPC: F02N11/08
Filed: 1980-02-12
Abstract: The engine stop button operates via a stop circuit. A start button resets the stop circuit and closes the starter motor's supply circuit long enough for the engine to start, i.e. long enough to attain a state - detected by a switch detecting the running of the engine - in which the starter motor's circuit is opened. A standby circuit puts the start switch on standby only after the ignition switch has closed and the engine has attained a given state, i.e. the detection switch has been operated. This prevents the engine being started inadvertently. A second detection switch is in series with the start button and senses when the engine is stationary. This switch ensures that the start button can only operate when the engine is not already running. A starter operating circuit may be used to close the starter motor's supply circuit automatically when the vehicle's speed exceeds a given limit after the engine has been stopped by the button.
Patent DE-3050290-A1 (DE)
Title: Electroplating current yield determn. - by depositing metal from sample electrolyte in cell and removing it by anodic etching
Inventor: VANGAEVER FRANK DR
IPC: C25D21/12
Filed: 1980-08-13
Abstract: The current yield during the metal deposition in electroplating baths is determined by taking a sample of the bath and by depositing metal from it on a revolving electrode in a measuring cell at a constant current (ik) and negative d.c. voltage for a given time (tk). The deposited layer is then removed by anodic etching at a reversed polarity and a constant current (ia), using a suitable electrolyte. A formula (I) is used to calculate from the ratio of the currents, multiplied by the times, the current yield (nk), na is the stripping current yield and where (ta) is the anodic stripping time. nk=(ia)x(ta)x(na)/(ik)x(tk) (I). Once the current yield is known, the operation can be controlled to maintain a constant layer thickness, esp. in the case of continuous pull-through electroplating plant.

Patent DE-3110910-A1 (DE)
Title: Envelope stacker
Inventor: STAMBERA ADOLF
IPC: B65H31/30
Filed: 1981-03-20
Abstract: The constant increase in the output capacity of machines for placing dispatch articles and mail in envelopes requires the employment of more operating staff to attend to the discharged envelope for the purpose of subsequent collection and stacking, for example according to the allotted post codes. This increased staff requirement is now countered in that the collection and stacking is carried out fully automatically. This is done by feeding the envelope discharged from the envelope machine to an envelope stacker. The latter comprises a feed conveying part (Fe) which optionally conveys in two opposite directions and is equipped with a switch (6) and a reading device (7), a stacking device (St) which follows said feed conveyor part (Fe) is controlled by the switch (6) and by the reading device (7) and receives the envelopes in a horizontal state, and of a lift conveyor device (H) which follows said stacking device (St) and transports the envelope stack thus formed to a discharge (A) disposed at normal working height. This novel envelope stacker makes it possible, by means of a printer controlled by the envelope machine itself, to provide the discharged envelope stack with a mark corresponding to the postal code of the envelopes forming the stack. <IMAGE>

Title: Hydrostatic axial transmission with a variable geometric volume
Inventor: GALBA VLADIMIR DIPL ING
IPC: F04B1/26
Filed: 1981-05-27
Abstract: The invention relates to a hydrostatic axial transmission case with a variable geometric volume and achieves the object of an advantageous arrangement of the means which serve for the alteration of the geometric volume and also the object of an advantageous configuration of the case for a hydrostatic axial transmission arranged in this way, the said transmission having a pivotable plate and a through drive shaft on which is mounted a cylinder block. The essence of the invention consists in the formation in the rear cover which closes the transmission case of two cylindrical openings which are connected to feed passages and in which are mounted the actuating pistons which are coupled to the pivotable plate. The arrangement of the actuating pistons and of the feed passages in the rear cover ensures a considerable reduction in the mass and the overall dimensions of the transmission, while the rigidity of the case and of the bearing arrangement for the pivotable plate are increased, and this has a favourable effect in terms of reducing the intensity of the operating noises of the transmission.

Title: Mains power supply protection device
Inventor: BUETTNER PETER DIPL ING
IPC: H02H3/00
Filed: 1981-08-19
Abstract: The monitoring and management of electrical power supply networks is carried out by means of mains power supply protection and mains power supply automation systems. The mains power supply protection device in this case has the task of monitoring all the equipment and of separating out the defective equipment in the event of a defect. The previous mains power supply protection devices were predominantly electromechanical or electronic relays. The object exists of creating a mains power supply protection device which consists of a relatively small number of electronic standard assemblies by means of which virtually all the fields of protection, such as busbar protection, distance protection and differential protection is covered, and which can be easily expanded by increasing the number of standard assemblies. In order to achieve this object, individual microprocessor systems are arranged in two hierarchial levels, the microprocessor systems in the second hierarchial level processing and transforming the digitised time-discrete measurement values of the phase variables in real time in such a manner that the microprocessor systems in the first hierarchial level calculate the protection algorithms and determine the defects using a reduced data set. <IMAGE>

IPC: G01R21/00
Filed: 1981-09-04
Abstract: To determine system variables such as power, direction of power flow and/or power factor in direct-current and/or alternating-current systems having arbitrary current shapes, voltage and current transformers are used which operate in accordance with the compensation principle and the secondary compensation currents (I1, I2) of which are the accurate equivalent of the primary current (IN, IV) which, however, is reduced in accordance with the transformation ratio. The compensation currents (I1, I2) are first conducted via in each case one separate resistor (R1, R2) and then via a common resistor (R3). The currents (I1, I2, I3) flowing in the three resistors (R1, R2, R3) are measured in a device (4), evaluated and indicated. <IMAGE>
