Title: Mobile crane jib support - has gantry erected by winch and folded by tie rope weight
Inventor: THELOKE KLAUS-JUERGEN ING GRAD
IPC: B66C23/72
Filed: 1974-04-06
Abstract: The support is for use on lorry-and rail-mounted of cranes having a crab travelling along a horizontal jib, and comprises a hinged gantry (B) erected by a motor-driven winch (A) so that the tie ropes (2) from the top of it support the jib head (C). When the winch pays out the rope (1) the gantry folds down onto the jib under the weight of the tie ropes into position (E), thus reducing the overall height to a figure convenient for travelling under bridges etc. Mathematical relationships involving the geometry of the system are also derived and given.

Title: Radio transmission system - uses single frequency for radio traffic one central station and several mobile stations
Inventor: JEROMIN JENS-PETER
IPC: H04B1/54
Filed: 1974-07-06
Abstract: Both central station and mobile stations have a sender and a receiver, and mobile stations are, when at rest, switched to reception. When the sending key is operated, each mobile station sends at regular intervals a certain voice frequency common to all. It is received and evaluated by all mobile stations switched to reception. When the frequency is received and recognised as correct the station sender is blocked for a period at least equal to the spacing between two consecutive emissions of the above frequency. After this time has elapsed, blocked sender is automatically released if the above frequency has not again been received in the meantime.

Title: Voltage controlled oscillator generating square wave pulse train - using Schmitt trigger, and transistor-transistor logic components contains operational amplifier
Inventor: FUCHS ERNST ALFRED DIPL ING
IPC: H03K3/03
Filed: 1974-09-16
Abstract: The circuit contains an operational amplifier (V) connected to a capacitor (C); and it includes a FET (FT), a Schmitt trigger (ST), diodes (D1, D2) and resistances (R1, R2). The amplifier and the capacitor (V, C) form an integrator with the integration-time controlled by the FET (FT).

Between switch points (P7, P8), the voltage (B) reaches a threshold e.g. +1.7 V, and between the given times the Schmitt trigger (ST) provides a signal (D) of +5 V, then during a given time this signal drops to zero V. The FET (FT), then discharges the capacitor (C) so that a threshold voltage of +0.9 is reached at a given time. The trigger (ST) is a TTL-gate.

Title: Yarn dyeing process - uses heated water passing through a mixing zone before entering dyeing vessel to gove rapid process action
Inventor: CHRIST WILHELM
IPC: D06B5/16
Filed: 1974-11-28
Abstract: A process and appts. are claimed for dyeing yarns, where the wound yarn packages are placed in a vessel for the dyestuff and other agents to be circulated through the charge. As the water is heated above the dyeing temp. in passing to the dyeing vessel, the fluid flow passes through a mixing zone where the dye is added to a constant mixing ratio. The dye is evenly distributed through the heated water with the dyeing auxiliary already mixed for the vessel to be filled rapidly. The process allows rapid dyeing of yarns, partic. of polyester where the dyeing temp. is >130 degrees C, with a controlled yarn absorbtion phase at the beginning of the dyeing process, eliminating the need for careful heating of the treatment bath with an exact temp. curve.

Title: Heat treatment of magnetic or piezoelectric powder - prior to moulding and sintering, comprising spray heating in controlled atmos
Inventor: GIESEKE WALTER DR RER NAT
IPC: C04B35/26
Filed: 1974-12-13
Abstract: Sintered bodies are made from ceramic powder by preheat treating or presintering the powder at 700-1100 (900-1000) degrees C by a localised heating process for 15-150(30-60) secs. in a gaseous atmosphere which may be inert, oxidising or reducing according to the nature of the matl. being treated, then forming a shaped body by any normal method, drying and firing. For ferrites, titanates zirconates, garnets, for electronics use e.g. for piezoelectric filters, ferrite pot cures, and for other similar substances. Reduced cost since the desalinated water used in the process can be readily recovered and reused. No other heating devices are heated and cooled, so that energy used in a minimum.

Title: Starterless ballast circuit for fluorescent lamps - has thermal relay shunting out resonant capacitor during electrode pre-heat
Inventor: STURM CARL HEINZ DR
IPC: H05B41/04
Filed: 1974-12-20
Abstract: The starterless ballast circuit, for fluorescent lamps, has the choke that is coupled in series with the lamp across the 220V supply provided with an auxiliary winding coupled to a resonant capacitor. During electrode pre-heating, the preheat current is increased by suppressing resonance. A thermal timing relay (5) is coupled in parallel with the resonant capacitor (3) and is arranged so that its contacts (4) open after the electrode preheat time has elapsed. A PTC resistor (7) may be used as a contactless switch. The advantage lies in making the preheat current at least partly independent of the start current.

Title: Hose coupling with automatic valves - has one valve opened when coupling is connected while other opens under supply pressure
Inventor: PFEIFFER ROBERT
IPC: F16L37/32
Filed: 1975-05-07
Abstract: Two valves (4, 6) are mounted in the coupling units which are mounted at the ends of hoses or pipes to be connected. When the coupling is broken, the valves are pressed by spring against valve seats in the coupling halves. The end faces of the valves have extension pieces which push against one another when the coupling halves are brought together. As the valve spring acting on one of the valves is stronger than the other, only one valve will be opened when the coupling is made. The second valve is opened when a medium under pressure is admitted to one of the hoses. The coupling halves are locked together by means of a row of balls which are mounted in holes in one coupling half and which engage with an annular groove in the other coupling half.

Title: Spheroidal graphite cast iron prodn. - using submerged magnesium packed in graphite or carbon fibre fabric or web
Inventor: UNDER WOLF DIPL ING DR
IPC: C21C1/10
Filed: 1975-07-25
Abstract: Spheroidal graphite cast iron is prepd. by treating cast iron melts with Mg, using a dip tank. The Mg metal is packed, on all sides, in a high temp.-resistant, gas-permeable fabric or web, consisting, at leat partly, of graphite or C fibres. Graphite- and C fibre fabrics and webs retain their gas-permeability above 1500 degrees C. Reaction of vaporising Mg is quiet and even.
