Title: PBX extension telephone set - has one key for selecting several connection functions including optional appliance remote start and stop circuit
Inventor: NEUMANN GERALD
IPC: H04M3/58
Filed: 1979-10-09
Abstract: A relatively slow but inexpensive selection circuit for a p.b.x. connects an exchange line to any p.b.x. line and enables any p.b.x. to select and communicate with a selected other p.b.x. or enables an external calling subscriber over an exchange line to set up, by remote control, one of several electric circuit switches e.g. to switch on or off a heating system, air conditioning system, etc. In the first case, an external call causes all extension bells to ring. If the answering station happens to be other than the desired one, the attendant presses a key which sets a bistable enabling a clock signal generator and a ring counter. The latter presents its binary output to the addressing circuit. When the right address appears, the key is pushed once more which resets the bistable and stops the counts. The barrier circuit is restored and the external line connection connects to the desired extension.

Patent DE-3018957-A1 (DE)
Title: Starting circuit for permanent magnet DC motor - applies current pulses when motor stops in switched-on condition
Inventor: VOLZ WOLFGANG
IPC: H02P6/20
Filed: 1980-05-17
Abstract: The circuit is applicable to permanent magnet dc motors with two armature coils which are alternately energised by switching transistors to produce an alternating field. The transistors are switched by a rotor position signal. Such a motor can, under certain circumstances, fail to start at switch on. As no further current pulses are applied no additional starting torque is available. The proposed circuit detects when the motor is stopped in a switched on condition, and then cyclically interrupts the supply to give consecutive current pulses until the machine runs. In a typical realisation, the detector uses the information (TS) from the rotor position sensor. It is applied to an integrating and switching circuit (2) which controls a multivibrator (1). With the motor running the vibrator gives a continuous output. When stopped the switching circuit (2,T1) turns off. A capacitor (C1) on the multivibrator charges and causes it to switch to the impulse output mode, and give the required current impulses to the motor (M).

Title: Fouling degree monitoring for degreasing solvent - by measuring rise of boiling temp. of solvent
Inventor: ZIRK WALDEMAR
IPC: G01N25/10
Filed: 1980-07-11
Abstract: The degree of fouling of a solvent, used in a plant for degreasing and cleaning workpieces by passing them through the vapour zone of a volatile solvent, is determined by measuring or recording the boiling temperature of the solvent in the heated liquid zone below the vapour zone. A thermometer or a thermoelement with an automatic triggering of a signal can be used to indicate that the max. permissible boiling temperature has been reached. This creates a reliable supervision of the solvent which requires a minimum of maintenance.

Patent DE-3107138-A1 (DE)
Title: Tidal power station
Inventor: BOCH KARL
IPC: F03B13/26
Filed: 1981-02-26
Abstract: Two tanks, tank A and tank B, of corresponding sizes are provided at the low-tide level of the sea. Tank B has to be a number of times greater, in terms of surface area, than tank A in order that the water flowing in from tank A rises more slowly. On the two tanks there are provided gates which, in the case of tank A, are opened inwards by the water pressure and, in the case of tank B, open outwards towards the sea. If the water then rises owing to the high tide, it opens the gates of tank A and flows in. In tank B, the gates are pressed back by the water and the latter cannot flow in. As soon as the water level in tank A is high enough, the water flows via a turbine into tank B, which is empty, and generates power. Owing to its size, tank B only fills up slowly. As soon as the water level outside in the case of low tide falls below the water level inside tank B, the water can flow back into the sea. Tank A has to contain enough water for the turbine to be able to operate until the new high tide appears and fills tank A up. The turbine will thus run continuously, regardless of whether the tide is high or low. The gates do not require any drive forces to open or close. This is effected by the low tide or high tide. Tank B should have a base surface which falls away slightly towards the sea in order to effect better and quicker discharge of the water. <IMAGE>

Title: Method and device for locating short circuits in circuit boards, wirings, lines, cables or the like
Inventor: BERNARD JUERGEN ING GRAD
IPC: G01R31/02
Filed: 1981-03-23
Abstract: An alternating voltage, the frequency of which is suitably between 5 kHz and 20 kHz for achieving a high efficiency, is applied to the conductors of a, for example, single- or multi-layer circuit board, which conductors are connected to one another by a short circuit. To keep down the influence of disturbing parallel capacitances, the audio-frequency alternating voltage is preferably superimposed on a direct voltage. To determine the course of the circuit closed by the short circuit, the magnetic field occurring along the conductors through which the current flows is detected by means of a movable electromagnetic probe (40). The signal occurring at the output of the probe, the amplitude of which changes as a function of the distance from the conductors through which the current flows, is rectified in a rectifier (42) and then used for generating a control voltage which drives a voltage-controlled oscillator (46). The output frequency of the voltage-controlled oscillator (46), which changes as a function of the amplitude of the output signal of the probe (40), is supplied to an electroacoustic transducer (50). The maximum output frequency of the voltage-controlled oscillator (46) is preferably 1.5 kHz. Since the human ear responds very finely to frequencies within the range up to 1.5 kHz, the conductor through which the current flows can be very easily and correctly traced, and the short circuit located, by moving the probe (40). <IMAGE>
