Patent DE-3018287-A1 (DE)
Title: PCB microwave ring modulator - has circuit board with etched metallisation providing slit and coplanar lines for input and oscillator voltages
Inventor: SEDLMAIR SIEGFRIED DIPL ING
IPC: H03D7/14
Filed: 1980-05-13
Abstract: The modulator uses from diodes (D1-D4) arranged in pairs, to which oscillator and signed voltages are supplied and from which the mixer frequency is obtained. The modulator is made using a printed circuit substrate(s) which is metallised on one side before etching to obtain the slit lines (8) and the coplanar lines (617). The hollow conductors (H1,H2) supplying the signal and oscillator energy have their end faces in contact with the metallised side of the substrate (8) in the region of the slit line (8) and the coplanar lines (6,7). The mixer frequency is tapped-off via microwave strip lines applied to the opposite side of the substrate (s). Pref. a slit line (8) formed in the metallised surface of the substrate is coupled to the inner conductors (4,5) of coplanar lines (6,7) on either side of it, coupled at their opposite ends to microwave strip lines (16.17) on the other side of the substrate associated with the arms of a T piece (T12). This is coupled to the IF output (III) via a quarter wavelength the slit line (13).

Title: Communication and location system for vehicles - has crossover track wiring HF communication path with priority emergency call procedure
Inventor: DJAMSHIDPOUR MASSOUD DIPL ING
IPC: G08G1/0967
Filed: 1980-05-24
Abstract: The communication, emergency call and control system use separate HF FM carriers for the transmit and receive paths along a track or roadway system wiring path to several vehicles. The system has dedicated time slots interleaved i- the speech for the cyclical interrogation of each vehicle to ascertain its position and for the receipt of emergency calls. All emergency calls are alarmed of the main control console and storage is used for holding alarm calls that are initiated whilst one is in progress or at the same time. Emergency calls are given priority over other calls and interrupt normal speech calls. Several vehicles are located along a track or roadway equipped with an electrical transmission path with periodic crossovers between the 'A' and 'B' legs. The crossovers are used for the positional location control of the vehicles which use an inductive coupling with the transmission path. At the main station a coupling to the transmission path is used to enable the positional cyclical scan equipment to interrogate vehicles in its time slot in conjunction with the speech and emergency control equipment.

Patent DE-3113763-A1 (DE)
Title: Vehicle crane with telescopic jib
Inventor: GINSTER WILLI
IPC: B66C23/82
Filed: 1981-04-04
Abstract: The jibs of telescopic cranes, which can be swivelled by means of a luffing cylinder, are subjected to bending loads of different magnitude depending on the jib length. The deflection resulting from this is dependent upon the stability of the jib, in which case a jib designed to be as rigid as possible is inevitably heavy. Since telescopic jibs with a construction which is as rigid as possible are at the same time to be designed to be as light as possible for weight-saving reasons, the aim of the present invention is to stabilise the jib system and thus ensure the lifting capacity of the vehicle crane by special staying of the telescopic jib. To this end, the invention proposes to arrange a stay beam (6) extending upwards transversely to the jib in the area of the articulation (4) of the luffing cylinder (12) at the basic jib. The free end of the stay beam (6) is connected via ropes (7, 8) to the head (11) and the foot (5) of the jib (1, 2).

IPC: H04R25/00
Filed: 1981-10-01
Abstract: A hearing device is proposed, the transistor amplifiers of which, including the control device for the functions of the amplifier, should be monolithically integratable. For this purpose, the control devices for setting the functions of the hearing device amplifier operate by using digital circuit means (20, 21, 22) in accordance with the principle of pulse-width modulation. The control devices exhibit an astable multivibrator (26), the duty ratio of which can be changed and which is constructed, for example, from inverter circuits (20, 21 and 22). To change the duty ratio of the astable multivibrator, an adjustment resistor (29) is provided. To adjust the volume the pulse sequence supplied by the astable multivibrator controls a transistor (18), the collector-emitter path of which is connected in series with a capacitor (19) in parallel with a resistor (15) which connects collector and base of a transistor (13) of an amplifier stage (12). <IMAGE>

Patent DE-3229528-A1 (DE)
Title: Diaphragm pump
Inventor: BECKER ERICH
IPC: F04B43/02
Filed: 1982-08-07
Abstract: A diaphragm pump is provided with a flow rate controller interacting with the flow. The inlet connection (12) communicates with an inlet valve (6) and at the same time with a damping chamber (10). The inflow volume of the latter is constrained and adjustable, preferably via a damping diaphragm (13), so as to damp pulse-shaped pressure surges of the inflowing pumped fluid in the suction region. A pulsating volume area of the damping chamber can also be achieved by adjusting a cross-section of a stream leading thereto. Depending on the extent to which the damping chamber becomes effective, smaller or larger amounts of intake volumes flow into the compression chamber (4) of the diaphragm pump. Correspondingly it is possible to increase or reduce the flow rate of the pump by means of changing the volume of the damping chamber (10). This adjustability is effected in a very simple and robust way by means of a rotatable adjusting knob (21). <IMAGE>
