Title: Control and information signal transmission in HV installations - uses light guides to eliminate electrical interference with interface units at ends
Inventor: HARTIG ALFRED DR ING
IPC: G01R15/22
Filed: 1978-02-13
Abstract: The object is to reduce interference in electronic control circuits caused by pick up in the leads connecting HV switching installations with a remote control centre. This interference is largely eliminated by employing fibre optics to link the equipment with the control centre. Optical interfaces are situated at each end of the light guide link. bundles of light guides can be taken to each piece of apparatus to transmit instructions, for example 'on' or 'off', check signals to verify the execution of an instruction, and information about the state of the apparatus.

Title: Timer control integrated circuit - uses comparison of charging voltage with reference voltages to generate hold signal for set period
Inventor: ARAI TAKAO
IPC: G11B15/02
Filed: 1978-04-28
Abstract: A timer control circuit for generation of a hold signal for a defined period after a voltage supply is switched on and then an operational signal for a second period is suitable for use in tape recorder control. It is designed to consist of an integrated circuit not requiring large numbers of connections to external components. A voltage comparator produces an output signal when the voltage produced by a charging circuit exceeds a reference voltage produced by a potential divider. A second comparator outputs a signal when the charging circuit timing voltage exceeds a higher reference voltage produced by the divider. A logic circuit produces a control signal from the comparator outputs.
Patent DE-2822788-A1 (DE)
Title: Motor vehicle driver reaction time control system - generates demand signal to driver on monotonous stretches of road requiring response
Inventor: BALOGH GYOERGY DR
IPC: A61B5/18
Filed: 1978-05-24
Abstract: The system is used for controlling and monitoring the reaction time of the motor vehicle driver. It generates signals to which the driver is obliged to respond on monotonous stretches of road. This improves safety in travel. The brake, direction indicators, gear drive, clutch, light signals and brakes control the delay of the signal requiring driver attention. When these monitored operating elements are not actuated, for example on long, straight stretches, then a demand signal is generated after a certain time period. If the driver does not respond to such a signal with required reaction, then a warning signal is generated and subsequently an alarm signal noticed also around the vehicle.

Patent DE-2854151-A1 (DE)
Inventor: PFLEGER KLAUS DIPL CHEM DR
IPC: C08F210/02
Filed: 1978-12-15
Abstract: A process for the continuous production of an ethylene copolymer by compressing a mixture of ethylene and comonomer in a pre-compressor and a post-compressor, copolymerizing the mixture in a polymerization zone at a high temperature and high pressure, transferring the reaction mixture into a high pressure product isolation zone, from there into a low pressure product isolation zone and thereafter into a discharge extruder, and recycling the greater part of the unconverted monomer into the polymerization process and passing a small part of the unconverted gas into a low temperature isolation zone, in which process a small part of the gas recycled from the high pressure product isolation zone is passed into the low temperature isolation zone, which is preferably under a pressure of from 10 to 30 bar and at from -10 DEG  to -50 DEG  C., and all the gas taken off the low pressure product isolation zone is fed to the pre-compressor. Using the novel process, the separating-off of the comonomer which has remained unconverted in the polymerization process can be improved.

Title: Hydraulic energy conversion system using e.g. high-level lake - alternately supplies drive bodies with fluid so that it descends to operates turbine
Inventor: HAUSHALTER GEORG
IPC: F03B17/02
Filed: 1979-03-10
Abstract: The energy conversion system uses a hydraulic pressure source as a hydraulic store. A drive body filled with fluid supplied energy to a generator as it descends and allows communication between two fluidic columns, one of which incorporates an empty second drive body. This supplies its remaining energy of descent to the generator, e.g. via a turbine, after equalisation of the fluid columns and upon fluid being supplied to it from an external pressure source so that it no longer floats. When the second drive body reaches its end position it is filled with fluid and when the first drive body reaches its end position it is empty, so that it again descends to supply energy to the generator. Pref. each drive body is supplied with fluid so that it begins its descent, before the descent of the other drive body is complete, each drive body contained in a shaft of similar height and coupled via a supply line with a hydraulic store at a higher level. e.g. a national lake or a reservoir.

Title: Multi axle fluid sprung trailer - has liftable axle with fluid displacing pump chambers and stop to retension spring when axle raised
Inventor: BREITHARDT HANS
IPC: B60G11/46
Filed: 1979-07-25
Abstract: The trailer vehicle has a number of rear axles (2-4) of which at least one (2) can be raised (by cylinder 36,37) and has a spring suspension (25) carried by a liftable sub-frame. This sub-frame carries at least one pressure chamber (27,28) which acts as spring tensioner (29). When the axle is raised and the spring (25) extends, this chamber (27,28) displaces fluid into chambers (40,41) which act as a pump. The expansion of these chambers is limited by a stop (47) on the vehicle chassis (5) so that, as the axle (2) is raised further, the fluid is pumped back into the chamber (27,28) to re-tension the spring (25).

Title: De-centralised electric power and heating plant - uses gas turbine to drive power generator and hot exhaust gases for heating purposes
Inventor: ARTMANN JOACHIM DR
IPC: F02C6/18
Filed: 1979-10-11
Abstract: The decentralised power plant is intended for family houses, block of flats, and possible small industrial plants. The combination of electric power and heat generation for a household can achieve up to 90% efficiency as compared with conventional 25 to 30% of normal power plants. The system uses a gas turbine for a generator drive, and the exhaust gas heat energy is used for heating or preparation of hot water. This system may be combined with solar energy collection, both for current generation and heating. The current generation may be provided by solar cells. The daily demand may be covered by heat storage arrangements, e.g. using electrochemical batteries. In case of a turbine failure a 12 V d.c. or 220 V a.c. starter may be applied for emergency operation.
