Patent DE-2364502-A1 (DE)
Title: Automatic laying of pipes in trenches - handling unit extracts pipes from magazine and positions them for seam welding in the trench
Inventor: FARKAS LASZLO
IPC: F16L1/036
Filed: 1973-12-24
Abstract: The laying of larger diameter pipes in a trench is mechanised to the extend that a days supply may be automatically fed from a magazine to the trench and seam welded in situ. The pipe sections are fed in a synchronised mode from the magazine to a hanging support that operates on rails, laid parallel to the trench. The hanging support automatically transports the pipe section until it is in end contact with the previously laid section. A transportale welding cabin is then located over the join and the pipe section is seam welded. The complete arrangement provides capacity sufficient for one days operation.

Title: Impulse stepping digital counter unit mechanism - with very cheap stepping arm requiring no adjustment or additional parts
Inventor: WAHNSCHAFFE KLAUS-DIETER
IPC: G06M1/04
Filed: 1974-01-30
Abstract: The mechanism achieves accurate counting with a simple non-adjustable arm. This is achieved by ensuring that the stepping arm will always return to behind the next tooth of the number-wheel after an impulse. Two mechanisms for achieving these aims are described. The number-wheel is injection moulded, with the sawtooth ratchet-wheel near the central axis, and a curved surface slot inside the periphery. The stepping arm of bronze lies on a tooth on the ratchet wheel and has a boss on one side projecting into the slot. The curves are formed so that when the arm returns the boss comes in contact with the curve for one tooth and is guided behind the next tooth. The second mechanism has bosses on the number-wheel, and a cam on the side of the stepping arm tip which guides it behind the next tooth.

Title: Capacitive crosstalk reduction in loudspeakers - all AC voltages induced in diaphragm are leaked to frame
Inventor: BACKES WOLFGANG
IPC: H04R3/00
Filed: 1974-04-23
Abstract: The loudspeakers have capacitive negative feed-back, and crosstalk is induced between the voice coil and motion pick-up. Voltage necessary for the electric field generation is applied to the diaphragm through an RC circuit. Its capacitance is such that its impedance at the lowest frequency to be transmitted is still small in comparison with the output resistance. The circuit resistor is sufficient to limit a short-circuit current, or a current due to the electrode moving to non-dangerous values. The loudspeaker membrane (M) is connected to the frame via a capacitor (C) and to a bias voltage (U) via a resistor (R).

Title: Power plant with exhaust driven super charger - has auxiliary combustion chamber for high performance requirements
Inventor: DINGER HANS DR ING
IPC: F01N5/04
Filed: 1974-06-07
Abstract: The power plant consists of a water cooled internal combustion engine (11) an air compressor (12) turned by a turbine (16) powered by the engines exhaust gases, a cooler (13) to cool the compressed air and an auxiliary combustion chamber (15) driving a separate turbine to turn the power units radiator cooling fan (14). Only sufficient air and fuel is fed to the auxiliary combustion chamber to maintain a stable low flame and the exhaust gases are fed to the cooling fan turbine (17) at low output. For sudden increased performance, the auxiliary exhaust gases are shunted by means of a valve (19) to the air compressor turbine (16). In the case of a stationary power plant where there is no slip stream to cool the radiator, the whole output from the auxiliary combustion chamber can be diverted to the cooling fan turbine.

Title: Quantitative averaging method for light pulse energy - has random pulses submitted to integrator and amplifier with internal trigger
Inventor: FUERCH GUENTER DIPL ING
IPC: G01J1/46
Filed: 1974-09-30
Abstract: The arrangement is for the quantitative measurement of light impulse energy or the average value of continuously emitted light and in particular for gas and solid body layers. An arrangement for single laser emitted impulses by a fast sampling oscillograph technique is mentioned.

Patent DE-2446953-A1 (DE)
Title: Duct press for making bales - has press die in duct to shape non-metallic material into tied bundles
Inventor: SCHAEFER ANTON
IPC: B65B27/12
Filed: 1974-10-02
Abstract: The press arrangement consists of a duct with gradually reducing cross section and a press housing mounted in front of the duct. A press-die moves in the housing. A second duct connects from the top of the arrangement to the press housing. The opening of this duct is cleared by the press-die when it is moved back, so that material to be compressed can be loaded into the housing through the vertical duct. The front face of the press die has a number of parallel wide grooves, through which the wires for tying the holes pass. The ridges between the grooves are of T section, with the sides of the T's overlapping one another. This prevents the material entering the grooves.

Title: Cylindrically wound choke with small accurate airgap - uses annular configuration concentric core wafers with radial airgap
Inventor: WEIGEL GEORG
IPC: H01F27/245
Filed: 1974-11-16
Abstract: A choke has a particular geometric form of winding and core arrangement such that a good accuracy of magnetic circuit airgap can be easily established. The core consists of a number of sets of concentric waves arranged in a cylindrical form and held in place by two yokes at the ends of the cylinder. The electric windings are wound round these from the centre of the cylinder to the circumference, radially, and produce a field round the cylinder. This magnetic circuit is interrupted by a radial airgap in the core wafers, and the properties of the choke are determined by the dimensions of this. The wafers are insulated from each other electrically to prevent eddy currents in the usual way, but additional airgaps exist between the various sets of wafers.

Title: Steam hair curling rod - has water holder with wick which when pressed against evaporator element passes steam through angled outlets
Inventor: WALTER HENRY J
IPC: A45D2/36
Filed: 1974-02-25
Abstract: The steam hair curling rod consists of a plastic handle in which is held a tubular metal curling rod and a pivoting spring loaded clip. Guides are provided between an operating lever and the handle through which the clip facing a heating rod is removable by a parallel displacement. The end of the curling rod is extended to hold a screw in the water holder. The water holder contains a wick whose end projects through the container front wall to end in a conical head. To produce steam the water holder is pushed upwards against a spring until the wick contacts the evaporator element at the end of a thermostatically controlled heater device. The steam produced passes down the body of the heater and out through outlet holes (134) in grooves which direct the steam at a tangent to the rod surface thus keeping it away from the users scalp.

Title: Carbon dioxide fire extinguisher system - has weighing device which permits pivoting of gas cylinder at specific weight loss
Inventor: KREE ERICH
IPC: A62C37/50

Title: Self tensioning snow chain - with locking ring in tensioner to take up slack at each end
IPC: B60C27/10
Filed: 1975-02-25
Abstract: The end of the tensioning chain on each side of the snow chain has a securing catch hinged to the chain at one end and with a clamping ring hinged some way along the catch. The clamping ring acts in conjunction with a securing lip to clamp the end of the tensioning chain, with the end of the catch hooked into the snow chain. The catch is self-locking with increasing tension on the chain tightening the catch. This eliminates the need to re-tighten the chain after it has been fitted. The clamp ring can receive the ends of two chains, one spaced either side an angle.
