Patent DE-2359228-A1 (DE)
Title: Automatic gambling machine for bingo game - has unequal numbers fixed deliberately and selected randomly
Inventor: SCHICKEDANZ WILLI DIPL ING
IPC: G07F17/32
Filed: 1973-11-28
Abstract: A store receives the input of the k numbers determined deliberately. A system produces k unequal random numbers from a total quantity of n numbers. A switching arrangement ascertains the number of times the deliberately determined numbers coincide with the random numbers. A device allocates a winning sum to the number of coincidental numbers and cause this sum to be paid out. Flip-flops can be used as a store for the deliberately determined numbers. The switching arrangement and AND elements with two inputs, one controlled by a deliberately selected number and the other by a randomly selected number.

Title: Injection mouldings, esp of porcelain crockery - using thixotropic transformation to assist water removal via porous mould
Inventor: WILDEN JOHANN
IPC: B28B1/24
Filed: 1973-12-07
Abstract: The dies are permeable to liqs. but not to ceramic particles and pressure is exerted on the plastic ceramic mass so it undergoes a thixotropic transformation to a quasi-liq. state and, on removing the pressure it reverts to the plastic state; water is extracted while the mass is in the quasi-liq. state. The ceramic mass is pref. forced through a jet at high speed for the transformation, during which partial phase sepn., e.g. of water, occurs, suitable speeds for stoneware being 5m/sec. min.; for crockery 20m/sec. min; and for porcelain 100m/sec. min.; and the Reynold's number should be min. 3000. The pref. mould is made of silica flour, max. 15 mu mixed with a plastic binder and hardened, and with a pore size of max 10 mu. Process provides uniform redn. of the water content from 22% to 14-16% so that a plastic ceramic mass known as "leather-hard" is obtd.

Title: Acoustic flow velocity measuring device - uses difference measurement between velocity of sound with and against current
Inventor: BECHTOLSHEIM ANDREAS VON
IPC: G01F1/66
Filed: 1974-08-01
Abstract: The flow velocity is measured by measuring the difference between velocity of sound with and against the current. Both measurements are made over the same test distance by the same measurement circuit. Sound velocity is measured by the sing-around method, and the difference frequency is counted by a reversible counter; or the sound velocity is calculated by an electronic calculator from the time one or a certain number of sound pulses take to travel over the test distance; or several test sections are operated in multiplex by a measurement circuit. In all cases a single test length and measuring circuit is used thereby keeping costs down.

Patent DE-2510163-A1 (DE)
Title: Therapeutic nerve stimulating apparatus - has regulator auromatically adjusting pulse interval when duration of impulse is varied
Inventor: BOETTCHER LUTZ DIPL ING
IPC: A61N1/36
Filed: 1975-03-08
Abstract: The generator produces the current impulses for the nerve stimulating apparatus. A regulator adjusts the duration of the pulse, and also therefore automatically influences the duration of the pulse interval, as the pulse length is varied. Hence the pulse interval increass with the pulse length. The regulator is divided into at least two zones, each part having a characteristic impulse interval of fixed duration, a potentiometer resistance in the regulator lying on a fixed direct voltage contains logarithmic characteristics and the voltage tapped from it simultaneously determines the direction of the pulse and of the interval. The system thus eliminates the requirement for two potentiometers to individually vary the pulse and the pulse interval.

Title: Test system for switch state of crosspoints in crossbar matrix - passes test signals through to output for detection
Inventor: SENF FRITZ DIPL ING
IPC: H04H20/10
Filed: 1975-05-30
Abstract: The test system, for checking the switch state of of crosspoint in a crossbar-type switching matrix, passes a test signal over the switched-through path to the output side of the crossbar matrix to a detector. The test signals are chosen so that they have no effect on the other signals or supplies being switched through by the matrix along the same path. The test signals are generated by a compound test source connected to the input side of the matrix and are evaluated by the detector in terms of amplitude and shape. The number of sources the compound test source is equal to the number of matrix inputs.

Title: Concrete floor and composition flooring expansion joint wedge - with hollow part through composite layer with elastic bracing cross arms
Inventor: PESCHKE HARALD
IPC: E04F15/14
Filed: 1975-08-29
Abstract: Expansion joints are provided in a concrete floor in a covering composite layer.
