Patent DE-2919209-A1 (DE)
Inventor: LENDL JOSEF
IPC: B41J35/23
Filed: 1979-05-12
Abstract: In typing and printing mechanisms, in particular having a disc-shaped type carrier (1), the view onto the written text must not be impeded by the type carrier itself or by the ink or correction ribbon. Consequently, as is generally the case in typewriters, the ink ribbon is lowered after each type impression. The device according to the invention relates to a cam control (19, 20, 21) which, by means of a motor whose direction of rotation can be reversed and appropriate cam follower arms (3, 6, 13), brings about in a simple manner the lifting and lowering of the type carrier of the ink ribbon and, if appropriate, of a correction ribbon. Additionally, the device has the possibility of moving the ink ribbon into the impression position alternately in two planes lying one above the other. This results in a more economical utilisation of the ink ribbon. <IMAGE>

Title: Synchronising system for turbine and generator - evaluates high or low frequency control pulses using timing and counting system
Inventor: LANGEN WERNER
IPC: H02J3/42
Filed: 1979-06-13
Abstract: The synchronising system for a turbine and generator set is designed to operate within forty to fifty seconds, usually considerably below this time. Two sets of control pulses are generated, one set having a higher frequency than the other. Close to the synchronising point, that is, the point of minimum difference between the actual and nominal speeds, the synchronising unit transmits pulses for higher or lower adjustment for a determined period of time, or counts them until a given value is obtained, then either the higher or lower frequency pulses are suppressed. A timer reverses the counter for a predetermined period and a second counter is operated until a set time has passed or a pulse value has been counted corresp. to that of the first counter. The pulses are then stopped. The control pulses are received byaflip-flop system and a Schmitt trigger.

Title: Economically powered heat pump - uses water in supply ducts under pressure for drive
Inventor: WANJURA HANS-JUERGEN DR MED
IPC: F25B27/00
Filed: 1979-09-28
Abstract: Instead of being driven by power supplied by a current of electricity, a heat pump makes use of water pressure from the water delivered to the supply network from the waterworks to provide its drive. This is economical in fuel and avoids the complication of a separate electric power supply. The system is esp. useful if the supply pressure is high and needs to be reduced before being fed into the domestic water system.

Title: Measuring low pressure in container - uses gas friction acting on turbo-molecular vacuum pump rotor with magnetic bearing
Inventor: BEECK UDO DIPL PHYS
IPC: G01L21/16
Filed: 1979-11-14
Abstract: The method for measuring low pressure in a container uses pressure dependent gas friction. The friction is measured from the associated variation in the revolution rate of the rotor of a turbomolecular vacuum pump. Alternatively, the time for the rotor to run up to a desired rate of revolution is used as the measure of pressure, or the time taken for the revolution rate to decrease from one defined value to another. A further approach involves measuring the rate of change of revolution rate whilst constant power is applied. Similarly, the power required in order to maintain a constant rate of revolution may be used as a measure of pressure.
Patent DE-2947703-A1 (DE)
Title: Spectrometer with multiple-channel transducer and store - has spectrum shift of several channels with simultaneous read=out of corresponding number of store channels
Inventor: WOLLNIK HERMANN PROF DR
IPC: G01J3/28
Filed: 1979-11-27
Abstract: The spectrometer has a dispersion device for separating the spectral components and an optoelectronic multi-channel transducer coupled to a multi-channel store. The range detected by the transducer is shifted relative to the spectrum by an amount corresponding to the width of several channels and its outout signals are fed to the respective channels of the store before shifting for adding to the previously entered contents. Before a further addition to the store contents these are transferred between channels by an amount corresponding to the transducer shift, so that several initial channels of the store are cleared and the contents of the corresponding number of the last channels are transferred to an additional number of store channels.
Patent DE-3001564-A1 (DE)

Patent DE-3012901-A1 (DE)
IPC: B32B15/08
Filed: 1980-04-02
Abstract: Fire batts, in particular consisting of water-containing sodium silicate, are introduced, in a parallel arrangement, into through-passages, such as ventilation lines, of structures in order, in the event of fire, to expand and form a plug preventing the fire from spreading. In order to keep the fire batts ready for use over a number of years, they have to be sealed into a sheeting in order to protect them from atmospheric influences. The sealing-in process provides that, by pushing the fire batt, with the end side in front, centrally into a separated-off piece of sheeting of predetermined length, said piece of sheeting is wrapped around the fire batt. After pressing on the wrapped-around piece of sheeting for the purpose of regulating the enclosed air quantity, the projecting sheeting edges are welded and trimmed.
