Title: Burglar alarm operated by Venetian blind - is set by lowering blind and gives alarm if blind moves
Inventor: SCHUMANN GUENTER
IPC: G08B13/08
Filed: 1979-10-26
Abstract: A venetian blind (1) inside a window (5) of a house has a conducting peg (6) on its bottom slat (3'). When the blind is lowered, the peg is inserted between a pair of spring contacts (8), fixed to the window frame, and short circuits them. The contacts are connected (10,12) to a battery (20), relay (14) and alarm master switch (18). With the switch on, the relay is energised, which holds open a contact in the alarm circuit. An intruder who breaks the window (5) has to move the blind to gain entry. This dislodges the peg (6) from the spring contacts (8) and the relay (14) drops out and closes the alarm circuit.

Title: Safety lock on backrests of vehicle seats
Inventor: OSTERHOLD WOLFGANG
IPC: B60N2/433
Filed: 1981-03-11
Abstract: In a safety lock for the backrest of a vehicle seat, a locking hook (20) is arranged on the said backrest or on the joint fittings which connect the backrest, which locking hook (20) permits, by means of its weight distribution, manual pivoting forward of the backrest (12) without the express actuation of an unlocking lever in order to make it easier for passengers to get into and out of the rear seats. In this case, the locking hook (20) has a thumb component which is provided with a control cam (21) and by means of which the overall centre of gravity of the pivotable locking hook is arranged in such a way that when the backrest (12) is pivoted forward, the locking hook (20) pivots automatically in relation to the holding pin (19) into an open position. The deceleration forces which occur during sudden braking of the vehicle bring about inertia forces on the locking hook (20), which forces counteract the effect of gravity and hold the locking hook (20) in its locked position so that the backrest (12) is prevented from tipping forwards in the event of sudden braking of the vehicle. <IMAGE>
Patent DE-3110119-A1 (DE)
Title: Indicator of the direction of power flow
Inventor: BLOSS GUENTER
IPC: G01R31/08
Filed: 1981-03-16
Abstract: When short circuits occur in the operation of electricity supply systems (predominantly medium-voltage systems in this case), it is attempted to find the source of the fault as quickly as possible. To find the fault quickly, short-circuit indicators are used. The short-circuit indicators hitherto used in practice could only be used in radial systems with one feed point. The indicator of the direction of power flow is capable of finding and indicating the power flow in a power system. This makes it possible to monitor ring systems and parallel systems having one or more feed points. The operation of the indicator of the direction of power flow is determined by the phase angle of the alternating voltage from a generator (Figure 1) being picked up and stored for a short period in the case of a short circuit (the alternating voltage drops to zero volts). Thus, the phase angle of the alternating voltage can be compared with the phase angle of the alternating current at the instant of the short circuit. The displacement in the phase angle between alternating current and alternating voltage allows the direction of power flow to be determined. <IMAGE>

Title: Method and device for producing multilayer mouldings from at least two PUR foam systems
Inventor: FUNCK HERBERT DR ING
IPC: B29C33/30
Filed: 1981-03-17
Abstract: According to the invention, one-part mouldings are produced from two different PUR reaction mixtures, the mouldings having a multilayer structure and the individual layers each having specific properties. For this purpose the mixing head travels in succession to the moulds, of the individual moulding stations, formed by the lower mould tool and the first upper mould tool and fills them with a first PUR reaction mixture. After the shortest possible curing time, the moulds are opened and the first upper mould tool is exchanged for the second upper mould tool. In the interim, the change-over valve in the mixing head is actuated, so that now the second PUR system, together with the blowing agent, passes into the mixing head. The moulds now formed by the at least partly cured first moulding layer and by the second upper mould tool are filled with metered amounts of the second PUR reaction mixture in the manner corresponding to the first moulding operation. <IMAGE>

Title: Portable millimetre-wavelength radio device for simplex speech transmission
Inventor: MEINEL HOLGER DIPL ING
IPC: H04B1/408
Filed: 1981-04-10
Abstract: A transmission oscillator (2) is frequency modulated via the supply voltage of its Gunn element. The transmission signal is forwarded via a transceiver switch (3) to an antenna (4). In the "receive" setting, part of the oscillator power is forwarded as a mixed signal to the receiver. The receiver is designed as a double heterodyne receiver with two IF mixers (5 and 7) whose second heterodyne oscillator (11) is swept by a saw-tooth generator (12) and is thus coupled with a search run. Once a receive channel has been located, the saw-tooth generator (12) is maintained at its last value and the heterodyne oscillator (11) is re-adjusted by an AFC signal (b) in such a way that it counteracts the frequency drift of the millimetre-wavelength oscillators. <IMAGE>

Title: Method for measuring the production of heat by microorganisms, and device for carrying out the same
Inventor: ANDREEV EVGENY FEDOROVIC
IPC: C12M1/34
Filed: 1981-04-18
Abstract: The device for carrying out the method for measuring the production of heat by microorganisms contains a fermenter (1), in which the cultivation of microorganisms is carried out in a nutrient medium at a prescribed cultivation temperature. A calorimeter (12) is in thermal contact with the fermenter (1) and is used to measure the production of heat in terms of the magnitude of the thermal flux deriving from the culture mixture. Provided in the fermenter (1) is a heat source (16) which is provided with a control loop (17) for feeding heat into the fermenter. The heat is directed from the heat source (16) to the nutrient medium and the culture mixture in an amount corresponding to the quantity of heat which is consumed for the processes of heat and mass exchange in the fermenter (1) and is dissipated therefrom. In this case, during the stage of cultivating the microorganisms the quantity of heat supplied is changed in accordance with the change in the processes of heat and mass exchange with the aid of a control loop (17) which consists of a device (18) for measuring the viscosity of the culture mixture, which is electrically connected to an electric motor (8) of a stirrer (7) arranged in the fermenter, a transducer (19) for converting the viscosity variable into a performance variable of the heat source and which is connected in the input side to the output of the device (18), and a controller (20) for the output of the heat source, which is connected on the input side to the output of the transducer (19) and on the output side to the heat source (16). The device also contains a device (22) for maintaining the temperature of the environment outside the fermenter, which is constant or equal to the culture mixture, and excludes possible losses of a portion of the flow of heat stemming from the culture mixture due to the exchange of heat with this environment, and a heat exchanger (13), which is in thermal contact with the calorimeter (12) and has a device (14) by means of which the temperature of its working surface is kept constant. <IMAGE>
