Title: Rapid testing of lacquers for crack sensitivity - using tensile force from penetration sphere under simulated weather conditions
Inventor: BOXHAMMER JOERG DR ING
IPC: G01N33/26
Filed: 1980-06-06
Abstract: The method is for rapidly testing lacquers for crack sensitivity and involves placing the lacquer on a carrier, esp. of metal, and subjecting it to simulated light and weather conditions and optically testing it for crack formation at defined time intervals. The method enables the measurement time to be minimised. A tensional force is applied to the lacquer sample at a different point during the time program of simulated testing. The sample is then tested for crack formation each time using a microscope and fluorescence analysis. The tensile force is produced by a penetrating body under load, e.g. a spherical metal body of 0.25mm dia. The liquid required for the fluorescence analysis may be applied by wetting the penetration body with it. The force is applied in a cycle of approx. from 10 to 100 hours.

Title: Arrangement for providing triggering pulses to a phase-gating-controlled rectifier
Inventor: MANCHEN HANS-JOACHIM DIPL ING
IPC: H02M3/315
Filed: 1981-02-28
Abstract: The invention relates to an arrangement for providing triggering pulses for a phase-gating-controlled rectifier for voltage regulation in the case of undervoltage and maximum conducting period, in the case of which a signal for time-related production of triggering pulses for the rectifier is obtained by analog comparison of a control variable (which is derived from the difference between a regulating variable and a reference variable) with a ramp function, and in the case of which means are provided for reliable triggering of the rectifier even in the event of undervoltage and the control variable falling below a defined limiting value in the control range. In order to achieve better utilisation of the maximum possible control range (conducting period) without limiting the operating reliability, it is proposed according to the invention that digital triggering-angle limiting be carried out for maximum current flow, in the case of which a defined digital signal (g) is obtained from the synchronising clock (e) for the ramp generator (108), which digital signal (g) directly initiates the triggering pulses (h) of a triggering-pulse forming stage (104) from the analog comparison, in the event of the signal (d) failing. <IMAGE>

Title: Information retrieval device
Inventor: SUMI YASUAKI
IPC: G06F17/28
Filed: 1981-03-26
Abstract: The device for information retrieval exhibits a multiplicity of read-only memories which in advance store a multiplicity of types of information items, and an operating keyboard for reading the information out of the multiplicity of read-only memories. Letters which are entered with the aid of a multiplicity of letter keys on the keypanel are loaded into a first register and the letters read out of the read-only memory are loaded into a second register, whereupon the two are compared with one another and an address based on a comparison is determined and loaded into an address register. The respective read-only memories have stored corresponding information in advance in addresses which are in each case common to the various read-only memories and a corresponding read-only memory is optionally activated in dependence on a change of the type by operating an information selection key on the keypanel, as a result of which the information is read out from the same address as is loaded in the address register. In consequence, information of another type which corresponds to the information of the type given is read out directly by simply changing the designation of the read-only memory.

Filed: 1981-07-29
Abstract: In a microprocessor-controlled gambling or entertainment device, for example a coin-operated automatic gambling machine promising a win, an analog coder codes the instantaneous angular position of one or more rotating circulating bodies. The analog coder supplies data, which essentially correspond to the instantaneous angular position, to the microprocessor in that the voltage is measured which is generated by the electrical resistance value between two points on the circumference of the circulating body. The voltage can be converted by an analog/digital converter into digital form and then supplied to the microprocessor as input value. <IMAGE>
Patent DE-3135613-A1 (DE)
Inventor: MUELLER HELMUT
IPC: B60L3/10
Filed: 1981-09-09
Abstract: In einem Drehstrom-Schienentriebfahrzeug, das durch Asynchronmotoren angetrieben wird, wird das folgende automatische Schleuderschutz-Verfahren angewendet: Mittels eines Impulsgebers wird der Zustand des Makro-Schlupfes zwischen den Treibrädern und den Schienen erfaßt, der auftritt, wenn die Zugkraft oberhalb der Haftwertgrenze liegt. Der Impulsgeber erzeugt hierbei einen Steuerimpuls, der ein Kommando für automatisches Sanden auslöst und zeitlich unmittelbar davor eine Verminderung der am Asynchronmotor anliegenden elektrischen Spannung. Durch diese Maßnahme wird die Drehmomentkennlinie des Motors derart geändert, daß sie anstelle des normalen steilen Verlaufes einen flacheren Verlauf annimmt. Hierdurch wird erreicht, daß die Zugkraft nahe an der effektiven Haftgrenze verbleibt, ohne diese zu überschreiten, wobei eine Rücknahme der Motorleistung unterbleibt.
