Title: Monitoring arrangement for big machines, e.g. presses, moulding machines - has optical rotation sensor scanning dangerous region for presence of body parts, e.g. hands
Inventor: DIETERLE GERHARD
IPC: F16P3/14
Filed: 1992-10-07
Abstract: The machine to be monitored has a working chamber (13) into which operators place their hands and in which hazardous processes can occur.

Title: Operating mode changeover method for transportable equipment - triggering changeover between transport and stationary operating modes according to detected shocks
Inventor: KUEHN HANS-ROBERT
IPC: G11B19/02
Filed: 1992-12-09
Abstract: The method involves using a shock sensor to cause the changeover into a transport operating mode and to trigger reversion to a stationary operating mode. The changeover to the transport operating mode is caused by the detection of a shock for a defined period (T) by the shock sensor. The time is restarted for each new shock, otherwise the equipment is changed back to stationary operating mode. When the changeover to transport mode occurs the gain in the shock sensitive control loop is increased. In stationary mode the resonant frequency of a shock sensitive assembly is reduced. USE/ADVANTAGE - For reproduction appts of entertainment electronics, e.g. optical appts, when relative movement takes place between recording carrier and sampling device. Enables equipment to be prepared for imminently anticipated shocks using low cost arrangement.
Patent DE-4242922-A1 (DE)
Inventor: DINGLER GERHARD
IPC: E04G9/05
Filed: 1992-12-18
Abstract: German Offenlegungsschrift 40 20 124 indicates that even forming boards made of plastic must have such a low coefficient of thermal conductivity that the setting concrete can cool down. If turning chips are used, these must be chemically cleaned since they have come into contact with lubricating drilling fluid. In addition, chips require an adhesive bridge to the plastic. The invention would like to avoid this type of pretreatment of the metal bodies. To do this, the invention uses ground foil shreds, where "ground" has a meaning in the sense of the technique of "cutting mills" or "cutting granulators". <IMAGE>

Title: Semiconductor DRAM operable in self-refreshing mode - has refreshing function signal generator operating in dependence on mode actuating signal
Inventor: TOBITA YOUICHI
IPC: G11C11/406
Filed: 1993-03-23
Abstract: The DRAM has a memory cell field with a number of dynamic memory cells in lines and columns. The refreshing function signal generator operates internally in dependence on a refreshing mode actuating signal. A delay (44, 47, 48) acts on the memory cycle start function signal to retard it by a preset time period in dependence on an internal refreshing function signal. A device blocks the data writing into a memory cell in dependence on the output signal of the delay circuit. The generator (1, 32) has a CBR detector (1) and a blocking device (32). The detector responds to the memory cycle start function signal, while the blocking device acts on the CBR detector output signal and generates the internal refreshing function signal. ADVANTAGE - Reduced number of limitations for sequencing in self-refreshing mode and prevents of faulty function.

Title: Method for controlling a coin-operated or entertainment gaming machine
Inventor: SCHOENE SIEGFRIED
IPC: G07F17/32
Filed: 1993-10-21
Abstract: The invention relates to a method for controlling a coin-operated or entertainment gaming machine which consists of generally known and conventional functional groups. The object of the invention is to propose a method for controlling a machine of this type, by means of which the time loss resulting from individual games running for a relatively long time is saved again in the subsequent games. This object is achieved, according to the invention, in that the debiting of the stake is carried out, with a constantly predetermined debiting cycle being maintained, at variable points in time between two starting phases of the random-controlled symbol-carrying indicator elements. According to the invention, after a game which lasts for a longer time than usual, the debiting of the stake is carried out in the subsequent games sooner than at the end of the running time of the random-controlled symbol-carrying indicator elements, but in such a way that the spacing between two debitings of stakes does not fall below a requisite minimum amount. After a series of games has elapsed with a usual playing time and with earlier debiting of the stake, a debiting of the stake once again occurs at the end of the running time of the random-controlled symbol-carrying indicator elements, with the result that the loss of playing time is then compensated by the game which lasts for a longer time than usual.
