Patent DE-2211102-A1 (DE)
Title: Fleece waddings - from continuous filaments of synthetic high polymers
Inventor: BAUER GUENTHER DR DIPL ING
IPC: D04H3/02
Filed: 1972-03-08
Abstract: Well bulked fleeces of parallel three-dimensionally crimped continuous single filaments of synthetic high polymers are produced by feeding a tow direct from molten spinning or from stock through >=1 dispersal jet. The tow is propelled through the jet by compressed air moving at a faster speed than that at which the tow is released, sufficient tension being thus imparted to the filaments to disentangle them as they pass through the widening chamber under gradually diminishing tension, to the crimp releasing arrangement oscillating transversely or longitudinally over the moving conveyor belt.

Title: Faulty line section indicating system for power distribution grids - has relays responding to short cct. currents and controlling alarm lights
Inventor: BRUNE BERNHARD DIPL-ING
IPC: H02H7/28
Filed: 1973-08-18
Abstract: The faulty line section indicating system for power distribution grids has a line relay inductively coupled to each section of the line with its own substation and responding to short circuit currents. The grid is supplied at both ends over two circuit breakers which are linked by a control line. Each substation and line relay are connected to an evaluator. When a short circuit occurs the second breaker operates and a control signal is passed to the evaluators. A second control signal is passed from the opposite end of the line to the evaluator monitoring the shorted section. A first relay connected to this evaluator becomes activated. The second circuit breaker opens after a delay, e.g. 300 msec., and the first relay is deactuated. This deactuation causes a second relay to oscillate and light up a blinker light indicating the faulty line section.

Title: Differential cylinder with increased hydraulic rigidity device - piston rod diameter is reduced and speed loss is balanced by auxiliary cylinder
Inventor: BUBECK FRIEDRICH
IPC: F15B11/00
Filed: 1973-11-05
Abstract: Increase in the hydraulic rigidity in differential cylinders, without loss in return speed, demands that the return speed is greater by the surface ratio of the piston faces than the operating speed at the same hydraulic feed volumes. The piston rod diameter is reduced and the resulting speed loss is balanced by the arrangement of an auxiliary differential cylinder whose annular chamber is acted upon by the hydraulic pump while its full chamber feeds the annular chamber of the operating cylinder. The elastic flexibility of the auxiliary cylinder is made ineffective by means of the non-return valve.

Patent DE-2409216-A1 (DE)
Inventor: MEYER ADOLF DIPL ING PROF DR
IPC: C04B14/38
Filed: 1974-02-27
Abstract: Mouldings with a cement-bonded matrix and mineral fibres which are incorporated therein but are not per se alkali-resistant, have a comparatively high but transient load-bearing capacity which can be extended in time by incorporating the mineral fibres in a local concentration into the matrix, preferably in the form of bundles and, for example, by mixing in, sprinkling in or placing into the matrix. Additional improvements can be obtained by extensive removal of the water from the matrix and subsequent surface coating of the mouldings and by further measures such as the use of additives, coating of the fibres and additional use of further reinforcing fibres or inserts.

Title: Controlled run up of DC motor - involves using resistor with negative temperature coefficient in series with motor with permanent field magnets
Inventor: STEINMANN HELMUT ING GRAD
IPC: H02P1/20
Filed: 1974-03-29
Abstract: The application is typically to battery driven permanent magnet excited motors where complex start up circuits are not required, for example fan motors for radiator cooling in motor vehicles. A resistor unit (12, 13) is placed in series with the motor and battery using material with a negative temperature coefficient. At starting, with the resistor cold, the current is limited by the high resistance, but as the resistor heats up due to the passage of current through it its ohmic value falls allowing the motor to eventually run up to full speed. A thermostat may be incorporated in the circuit to switch off the motor when the cooling water temperature is low.

Patent DE-2427387-A1 (DE)
Title: Pulse edge coincidence detection cct - for digital data transmission using diphase data sync in PABX telephone system
Inventor: THOMAS JAMES HOUGHTON
IPC: H04Q11/04
Filed: 1974-06-06
Abstract: A clock signal is transmitted from the switch to the remote phone with the outgoing data and therefore the timing of received signal depends on the timing of the outgoing data. The invention provides compensation to the outgoing signal and as a consequence only very simple circuitry is involved. A detection circuit comprising an exclusive OR gate and a D-type flip-flop receives the data from the phone and a specially derived strobe pulse which is related to the system clock. When a coincidence is detected, the detection circuit provides an output to invert a clock signal which clocks the outgoing data thus introducing a delay equal to half the period of the clock. The circuit is locked in position to cause the delay unless a further transition coincidence occurs which can only happen under normal circumstances if the length of the line is altered.
