Patent DE-19531870-A1 (DE)
Title: Fuel injection system for IC engines, especially quick running two stroke engines
Inventor: REMBOLD HELMUT DIPL ING
IPC: F02M37/00
Filed: 1995-08-30
Abstract: The fuel injection system has a stepped piston (7) in the working chamber bore. The pressure of the fuel supplied by the pressure supply pump (1), is controllable by a pressure control valve (32), branched between a working chamber (25) and the auxiliary NRV (4). A choke (29) is provided between the electrically controlled valve (27) in the discharge line (26) and the auxiliary NRV. With the electrically controlled valve (27) opened, the stepped piston is raised by an amount, so that it moves against the spring (24), then returns. The pressure in the pressure chamber (11) is increased, so that correspondingly, an injection of fuel takes place, with an amount displaced from the smaller stepped piston part (18). The stepped piston effects a pressure change and a pressure increase in the pressure chamber (11), compared to the pressure in the pressure line (3). The NRV (10) prevents the reduction of the pressure in this line (3).

Title: Principle of coin=operated entertainment machine
Inventor: NIEDERLEIN HORST
IPC: G07F17/34
Filed: 1995-11-03
Abstract: A fruit machine has rotating discs showing the winning or losing combination of symbols behind viewing windows. A stop button (23, 24) for a rotating disc (5) indicates an acoustic or optical signal for a short time interval during which the disc can be stopped by the user at a position which is predetermined by a microprocessor. The time interval is limited to the average reaction time of the user and/or a minimum stopping time of the disc. If the stop button is not pressed within the time interval the disc continues to run for the normal time set by the microprocessor. A win or bonus is awarded if the button is pressed during the time interval.
Patent DE-19541238-A1 (DE)
Title: Tempering device for prodn. of thermally homogeneous gas flow
Inventor: HIEKE ANDREAS DIPL PHYS DR
IPC: B01L7/00
Filed: 1995-11-06
Abstract: The device is for highly accurate tempering of freely accessible samples by a gas. A gas, whose temp. is regulated, is passed from the side over a sample relative to its length axis so that the gas forms a flow field with a centre of flow of constant temp., within which the sample to be tempered is completely enclosed. The gas temp. measurement in the flow centre, and thus the sample temp. along its length axis, is directly measured above or below the sample. The measured temp. is used as the actual value for control.  Also claimed is a process to produce a thermally homogeneous gas stream by tempering as above, in which gas is fed into a vessel of insulating walls, inside which there are good thermally conducting structures for whirling and thermal equalisation of the gas. During this feeding, the gas can be cooled or heated. The gas can leave the vessel via a turbulence cell like structure in the vessel or in thermal contact with it, which leads to the formation of a flow field.

Patent DE-19618470-A1 (DE)
Inventor: ADAM CHRISTOF
IPC: H04M1/72505
Filed: 1996-05-08
Abstract: The connection method involves using code converters allowing the speech signals provided by the subscribers (21.23) and coded at a relatively low bit rate, to be transmitted via digital network channels of higher bit rate. The called subscriber is signalled when the connection is established from a calling subscriber, providing speech signals coded at the lower bit rate, with evaluation of the signalisation for the transmission of speech signals coded at the lower bit rate, from the called subscriber to the calling subscriber.   When the called subscriber cannot provide speech signals coded at the lower bit rate, the signals at the higher bit rate are fed back to the calling subscriber.
