Patent DE-3027147-A1 (DE)
Title: Telephone exchange circuit reconnecting calls at subscriber's request - advises caller that reconnection will occur but with facility for cancelling call if inconvenient, e.g. not in office
Inventor: FREYMADL GEORG DIPL ING
IPC: H04M15/12
Filed: 1980-07-17
Abstract: The automatic electronic telephone exchange provides facilities for reconnecting incoming calls to a different number at the subscribers request. Such a request is stored in a memory and acted on automatically if a call to the original number is not answered within a set time. Reconnecting a call in this manner amounts to setting up a second call. Also the reconnected call could involve a trunk connection. This can lead to higher charges than a caller anticipated when dialling the original number. To appraise a caller that a condition involving a reconnection exists an audible signal is sent out by the exchange to the caller. At the same time information about the charge rate which will apply for the call is also transmitted to the caller. He is then allowed a set time interval in which to terminate the connection without charge. The proposed information can be transmitted to the caller also in the case where the reconnected part of the call is chargeable to the subscriber being called.

Patent DE-3106122-A1 (DE)
Title: Motor cycle
Inventor: KAWAMURA SADAO
IPC: B60G17/00
Filed: 1981-02-19
Abstract: A motor cycle whose frame (1) has front and rear telescopic suspensions (2, 6 and 3, 7) which are connected to the axles of the two wheels (4, 5) is provided with a vertical adjustment system which has a high-pressure air container (18) which is connected to the two telescopic suspensions and fed from an air pump (19) which is driven by a motor (20) which itself receives current from a battery (23). A movable contact (25) which is driven by the tachometer of the motor cycle interacts with a fixed contact (26) when the motorcycle is either stationary or travelling at low speed and this movable contact closes a circuit which causes venting valves (10, 11) to be opened in order to let the air out of the telescopic suspensions (2, 3). Solenoid valves (16, 17) at the same time vent the container (18) via non-return valves (14, 15). If the motor cycle is ridden at a relatively high speed, the movable contact (25) interacts with a second fixed contact (27), as a result of which the engine (20) starts up and drives the pump (19) so that the container (18) is filled with compressed air. The venting valves (10, 11) are closed and the rise in pressure lifts up the frame of the motor cycle until a predetermined pressure is obtained in the system, which pressure actuates two pressure-dependent switches (12, 13) in order to close the valves (16, 17) and keep the engine (20) running. <IMAGE>

Patent DE-3122770-A1 (DE)
Inventor: FOERSTER SIGFRIED DR
IPC: F23K5/00
Filed: 1981-06-09
Abstract: A process and an arrangement for the formation of an ignitable mixture from liquid fuel and combustion air, wherein preheated combustion air is conducted with a flow chamber along a surface which is moistened with fuel for take-up of fuel. In the process and arrangement, combustion air is conveyed into the flow chamber in the flow direction of the fuel which streams off the surface moistened by the fuel under the effect of gravity. Achieved hereby is an intensive contacting between the combustion air and the fuel. The fuel is dosed in excess so as to constantly afford a sufficient quantity of fuel for vaporization. During the through flow of the combustion air, there is formed, in the contact with the fuel, a saturated fuel-air mixture in conformance with the temperature of the preheated combustion air and the temperature of the fuel. Concurrently, care is taken that the trickling film of the fuel which is formed by gravitation as well as the drag effect exerted by the combustion air passing through the flow chamber can freely exit from the flow chamber at the foot of the surface moistened by fuel, to the extent in which the fuel is not taken up through vaporation by the combustion air in the flow chamber.
