Title: Washing machine water flow controller - has two switches operating solenoid valve and acoustic alarm w.r.t. connection state
Inventor: GREISINGER ELISABETH
IPC: D06F39/08
Filed: 1979-06-09
Abstract: Installation of the water flow controller in a washing machine without the aid of tools and carried out by the layman is ensured by the control and alarm unit (I). It includes an earthed plug for insertion into the washing machine and a relay operating the solenoid valve to which it is connected by conductor (10). The valve is controlled by an additional switch (14), the deenergisation of the valve solenoid ensuring that mechanically it is in the closed position for stopping the water flow. Cable (15) terminates with a water sensor (16) fitted with two electrodes (17). The solenoid valve is connected to water inlet by an union nut of the water cock and a similar nut ensures its connection to the washing machine inlet. The acoustic alarm (II) is switched off by switch (14), and lamp (12) indicates that the unit is ready for the operation.

Title: Auxiliary battery charger for no break power supply - is for charging individual sections to gassing point to maintain battery performance
Inventor: BARTMANN WERNER
IPC: H01M10/44
Filed: 1979-07-14
Abstract: The application is to uninterruptable power supplies for dc loads which have to operate within close limits of maximum and minimum voltage. The main rectifier and regulator (1) feeds the load (2), and also charges the battery (3). As the battery delivers no current under normal conditions, its output performance may deteriorate, for example due to high local acid concentration in a lead acid cell. To avoid this condition each battery section (3.1, 3.2,3.3) in turn is charged to the gassing point in order to give good mixing of the electrolyte. By charging one section at a time the output voltage is maintained within the limits defined for the load. The auxiliary charger (4) is typically an unregulated dc supply. It is switched (5) in turn to each battery section. Switching may be determined by a timer, by evolution of gas, or some similar means.

Title: Overload safety device for rolling mills - where strain gauge in electric monitor circuit causes fracture of safety plate if overload occurs
Inventor: GUST KARL
IPC: F16P5/00
Filed: 1979-08-28
Abstract: The mill includes work rolls which are located on chocks pressed against adjusting spindles employed to provide a specified roll gap. Between the chocks and the spindles is a hydraulic chamber and a plate which fractures when a load of 60-85% of the max. permissible stress for the mill is reached. An electric load indicator, e.g. a strain gauge, is located on the parts of the mill subjected to stress, e.g. on the stands, and is used to trigger a hydraulic circuit which fracture plate. The overload device is not damaged when used on heavy duty mills.

The two elements are spaced apart by a gap which is less than the wavelength of the operating frequency. The largest diameter of the elements is between 1/7 and 1/10 of the diameter of the sub-reflector. The ratio of the diameters of the two elements is between 1:3 and 1:4. The two elements have different angles of slope.

Patent DE-3001953-A1 (DE)
Title: Textile winding machine having moving traverse mechanism - with closely set disc-shaped driving elements moving in opposite directions along path of transverse movement
Inventor: HILL GRENVILLE MOORE
IPC: B65H54/28
Filed: 1980-01-21
Abstract: A textile winding machine has a moving traverse mechanism with disc-shaped yarn driving elements set close together, and moving in opposite directions along the path of transverse movement. The yarn is transferred from one driving element to the other, moving in the opposite direction at each end of the traverse span. A positioning yarn guide is placed in the yarn path leading to the moving traverse mechanism, and supplementary control means act upon the yarn as it passes between the positioning guide and the moving traverse mechanism. The control means extend the traverse movement outwardly from the points of transfer so that the length of the movement, measured at a point in front of the point where the yarn reaches the moving traverse, is greater than the distance between the points of transfer. The outward extension of the traverse movement effectively prevents an undesirable inward movement of the yarn wound on the package. Such inward movement results in a slight softening of the yarn and a momentary loss of tension, which in turn gives rise to the 'hard shoulders' and 'spiders'webs' found on poorly wound packages.

Title: Schmitt trigger with signal-dependent hysteresis - has operational amplifier with non-inverting input grounded via RC circuit
Inventor: RUTHEMANN KLAUS DIPL ING
IPC: H03K3/0233
Filed: 1980-04-24
Abstract: The Schmitt trigger circuit is arranged so that its hysteresis is dependent on the amplitude of the input voltage and consists of a differential amplifier or operational amplifier whose inverting input is the signal input. A resistor (R1) connects the amplifier output back to the non-inverting input. The non-inverting input is connected via a second and a third resistor (R2, R3)in series to ground. The third resistor (R3) is shunted by a capacitor (C). The first resistor is much greater than the second resistor, and the third resistor is much greater than the second resistor. The advantage lies in input-dependent hysteresis. The trigger is also less likely to oscillate.

Title: Plastics casing esp. for construction site electrical equipment - made by casing transverse panels into wound glass fibre reinforced shell
Inventor: STEUDE VOLKER
IPC: B29C70/46
Filed: 1980-07-04
Abstract: Mfr. of a box-shaped housing, esp. a casing for electrical equipment for use on construction sites, operates on the principle of making the glass fibre reinforced plastics casing by winding on a core. Transverse walls, panels, etc. contg. apertures are fixed in this core, their edges protruding slightly beyond the intended internal periphery of the casing, so that as the casing is wound and cast the edges of the panels become thoroughly fixed and embedded in it. Pref. the edges of these transverse panels are previously ground to remove any impurities which could damage the plastics of the surrounding casing. The surrounding casing itself may be cast in an external mould. The method is time-saving and ensures fixity and sealing of the transverse panels in the casing wall.
