Title: Operating device for appliances, in particular for transceivers
Inventor: DREER HERMANN DIPL ING
IPC: G06F3/0488
Filed: 1989-01-02
Abstract: An operating device is proposed for appliances, in particular for transceivers, in which the display device which displays the different functions of the appliance at the same time forms the actuating devices for the different functions. The display unit is a flat, pressure-sensitive display unit (1) which is provided with a matrix-shaped control. The individual functions can be displayed as a function of the control on display areas at various points of the display unit. Furthermore, a control unit (3) having a memory (storage) (4) and a comparing device (5) is provided, the address allocation of the individual functions with respect to the various points or display areas of the display unit being stored in the memory. For actuating and triggering a function pressure is applied to the point of the display unit which is allocated to the function, the respective current-voltage ratio being changed by the change in pressure. The control unit and the comparing device detect at which addresses the changes in pressure have occurred and assign these addresses to the functions, and the control unit transmits a corresponding control signal. <IMAGE>

Title: Additional part for a universal slicer
Inventor: WOLF OSKAR
IPC: B23D47/04
Filed: 1989-01-03
Abstract: In the so-called universal slicer it is possible to use the same gearwheel which drives the revolving blade to drive a circular saw blade in addition. Conversion of the sausage-pressing part respectively so as to provide a larger wall which is parallel to the cutting depth adjustment unit wall to provide a larger surface and insertion of a through hole make it possible to cut into or sever the necks of plastic bottles without difficulty and in so doing to relegate returnable bottles to refuse since, unlike glass, the material from which such used bottles are made has an extremely small value and it is therefore madness from an economic viewpoint to go to the expense of returning it to the filler, who may even send it to the dump in any case.

Patent DE-3934569-A1 (DE)
Inventor: KUERTEN RUDOLF AUGUST
IPC: B41F15/46
Filed: 1989-10-17
Abstract: In a method for adjusting the position of a printing squeegee and a flood squeegee in screen printing, the position-adjusting force, with which the printing squeegee is pressed against the fixed base of the printing carrier, and the position-adjusting force, with which the flood squeegee is pressed against the printing medium applied to the screen stencil during the flooding operation, are generated in each case by a pneumatic or hydraulic control circuit which is independent of the control circuit of the flood squeegee or the printing squeegee, the respective position-adjusting force being optimised by setting the pressure of the pressure medium initially in one or more trial prints or from empirical values and then being kept constant at this determined value in the following prints. A device for carrying out this method employs at least one cylinder unit for generating the respective position-adjusting force and a pressure controller for keeping the pressure of the pressure medium constant, the control circuit of the cylinder unit for the flood squeegee being independent of the control circuit of the cylinder unit for the printing squeegee. To compensate for the weight, the flood squeegee is prestressed in the direction facing away from the screen stencil.

Inventor: HENDRICK FRED WOODSON
IPC: F16K3/08
Filed: 1989-10-25
Abstract: A disc valve has cooperating apertured discs 22, 31 in face to face contact, the disc 22 being rotatable and the disc 31 being non-rotatable. The discs 22 and 31 are located upstream of a sleeve member 33 at an outlet chamber of the valve. The sleeve member 33 includes a truncated conical portion to produce a desired pressure drop, while, at the same time reducing the turbulence of the fluid flow during operation of the valve. The sleeve member 33 is maintained in position by way of pressure of the fluid, thereby avoiding the necessity of adhesive or other means to hold the sleeve member to the valve body. The sleeve can be provided with an end wall 45 with a discharge opening 46 of a predetermined size at the downstream end of the sleeve for producing a predetermined fluid pressure drop. <IMAGE>

After this is attained, by altering a pressure adjustment value the pressure of the refrigerant in a condenser (2) is increased up to its max.  possible value. A monitoring unit (42) is provided, which by an output unit (45) delivers a fault signal, if over a predetermined time span the expansion valve (4) stays in the region of the max. degree of opening and the pressure-adjustment variable assumes its max.  value. USE/ADVANTAGE - Refrigeration plant. With defective sealing, the smallest possible damage to the environment occurs due to unnoticed escaping refrigerant.
