Title: Telephone call answering system
Inventor: TRUMPP GERHARD DIPL-ING
IPC: H04M1/64
Filed: 1982-08-31
Granted: 1983-12-15
Abstract: Telephone call answering system with a memory in which a signal, i.e. a reply of the called owner of the telephone call answering machine and/or a message of the calling third party is stored, in delta modulation with two-way amplitude limitation of the analog signal. The storage capacity is exploited more fully by storing pauses between analog signal components, e.g. speech pauses between two words of a sentence, in each case in the form of a digitally represented number corresponding to the duration of the pause concerned, and a number of uniform digits, e.g. a number of "1" bits, greater than the number corresponding to the amplitude limitation of the analog signal, is added before and/or after this number in order to identify it. <IMAGE>

Patent DE-3837909-C1 (DE)
Title: Method and arrangement for measuring speed and displacement in the case of motive power (tractive) units providing total adhesion
IPC: G01P3/42
Filed: 1988-11-04
Granted: 1990-01-18
Abstract: The aim is to specify a simple method together with a simple arrangement for measuring the speed and displacement with relatively high accuracy as the wheels rotate. In this case, the wheel slip errors can largely be eliminated even without reducing the tractive or braking forces. In the case of motive power units providing total adhesion which exhibit tractive/braking force control and subordinate control of the wheel slip in which the wheel sets are controlled in the event of overshooting of the adhesion (adherence, grip) and response of the wheel slip controller via the tractive/braking force in such a way that they move at optimum adhesion or in the vicinity thereof, it is proposed according to the invention that the slip-affected speed which can be determined from the rotational speeds, or the corresponding displacement is corrected by amounts of slip which are different and depend on the response or non-response of the wheel slip controller. In these two operating states the slip correction amounts are respectively determined from the wheel slips occurring there most frequently in statistical terms in the case of specific tractive/braking forces (f1(F); f2(F)) and speeds (f1(v); f2(v)), taking account of the rail condition parameters. It is possible by means of the invention to use the wheel slip controller, present in any case, and the speed governor (regulator) to achieve in a simple way a satisfactorily accurate measurement of speed and displacement. <IMAGE>

Title: Vehicle heating device with at least two air-inlet flows, the temperatures of which are controlled in different ways
IPC: B60H1/00
Filed: 1989-04-08
Granted: 1990-10-04
Abstract: In a vehicle heating device a portion of the outgoing-air flow only flows through a subregion of the heat exchanger and is accordingly subject to less temperature control. In the process, this portion of the outgoing-air flow penetrates the subregion of the heat exchanger essentially orthogonally with respect to the direction of throughflow of the other outgoing-air flow, which flows through the entire heat exchanger and is hence subject to more pronounced temperature control. As a result, a defined temperature layering can be obtained in a simple manner in the passenger compartment.

Title: Process for cleaning a well shaft
Inventor: MUNDING HARALD
IPC: F04F1/06
Filed: 1992-12-21
Granted: 1994-09-01
Abstract: The invention relates to a process for cleaning a well shaft and a through-passage openings present in the shaft wall, and the layers of gravel which border the shaft wall immediately behind the latter, using a multi-level framework which can move along the well shaft and has horizontal partitioning elements forming at least one operating chamber, which, by being subjected to the action of a pressure medium, forces the well water through the through-passage openings into the bordering layers of gravel. The multi-level framework exhibits a riser pipe which opens in the operating chamber, bounded by two partitioning elements, and is lowered into the well-water-tunnelling well-shaft region such that well water rises up in the riser pipe. The riser pipe is subjected in a pulsating manner to the action of compressed air, as pressure medium, such that, upon being subjected to the action of pressure, the well water flows through the through-passage openings of the shaft wall into the bordering layers of gravel and, in the event of the compressed air being let out, said well water flows back into the operating chamber and the riser pipe again.
