Patent DE-2334765-A1 (DE)
Title: Liquid filler and decanter for chemicals - common actuator controls valve sequence and filler tube
Inventor: WILDI HANS
IPC: B67C3/24
Filed: 1973-07-09
Abstract: Filling system for fluids, e.g. aggressive chemicals, operates by means of a filler tube. One of its two valves is mounted at the outlet end of this tube, though both are operated by the smae actuator. This works against a restoring force to open the first valve before the second and when the actuator is returned, the first valve closes after the second. Preferably the first valve closer and actuator is an adjustable sleeve on the tube which closes this in the forward setting. The tube should also be adjustable and carry the second valve seal at the rear end so that this seats when the tube is fully forward, thus closing the second valve. A stop on the tube within the adjustment path of the sleeve entrains the tube rearwards, thus opening the second valve.

Title: Paper sheet laying-up machine - with band conveyors operation at different rotation speeds
Inventor: MAY FRITZ DIPL-ING
IPC: B65H29/66
Filed: 1973-07-12
Abstract: The laying-up machine is for sheets of paper, foil or similar materials used in printing and other paper processing machines. A first band conveyor rotates at a reduced speed and supplies the sheets to the laying up installation and is positioned so that after the transfer of the sheets from the band conveyors rotating at high speed to the band conveyor running at low speed the upper side of the first sheet adjoines the lower side of the succeeding sheet. An installation located between the two band conveyors reverses the sheet movement and the end of the sheet movement reverses the position of first and succeeding sheet in relation to each other.

Title: Logic fluid programme circuit has two valve sections - one valve section is operated by hand and other is hydraulically operated
Inventor: OHISHI MASATERU
IPC: G05B19/43
Filed: 1973-08-31
Abstract: Logic fluid programme circuit where a first valve section has a casing with inlet and outlet and a plunger piston and means to load the piston in one direction into a first position where this first valve section is so operated by hand that the piston can be moved into a second position in the opposite direction. a second similarly equipped and operating valve section is operated to move its piston to a second position when a pressurised fluid medium is fed to its piston via the inlet of the second valve section. consequently, there is a connection between the outlets at the rest position of the first valve section and a connection between the outlet and the inlet of the first valve section on operating the first valve section.
Patent DE-2352325-A1 (DE)
Title: Valve for discharging condensate - opens in response to rise in pressure drop across restrictor blocked by liquid
Inventor: KALB HANS
IPC: F16T1/12
Filed: 1973-10-16
Abstract: The valve member is arranged for its area exposed to pressure in an upstream chamber to be smaller than the area exposed to pressure in a downstream chamber so that gaseous flow between the chambers through a restricted inlet in the member tends to keep the valve closed. The pressure in the downstream chamber is maintained by a restricted outlet therefrom which is so set, that when the flow becomes liquid due to condensation, the resulting rise in pressure drop across the restricted inlet, and consequent drop in pressure in the downstream chamber, causes the valve member to be moved into the open position by then superior upstream pressure.
Patent DE-2359416-A1 (DE)
Title: Protective housing for microphones and loudspeakers - consists of double or single cage of magnetically well permeable material
Inventor: NEUMANN GOTTFRIED
IPC: H04R1/10
Filed: 1973-11-29
Abstract: The housing may consist of two concentric cages, and a magnetic field is generated between these two cages, using several permanent magnets inserted between the two cages; the magnetic field strength increases sideways from the sound inlet or outlet and the cages are removable. The apparatus may be used in an environment in which there is a high concentration of dust, and in which magnetic iron and iron oxide dust may be present. The cages are of basket shape to give a good clearance between the cages and the loudspeaker mechanism. The cages may be made of ferrite and the dust is trapped between the two cages by the magnetic field.

Title: Supply valve for ink jet printer - has conical valve member forced down into funnel-shaped seating
Inventor: SICKING HEINRICH
IPC: B41J2/175
Filed: 1974-04-06
Abstract: An arrangement for connection and disconnection of the ink supply to an ink jet printer, where a good seal is necessary to prevent introduction of air, includes a conical valve member inside the outlet of the ink container and a funnel shaped seating in a cup shaped member acting as a valve for the ink supply line. The conical member is resiliently mounted so that when the container is pushed down, ink can flow around it. At the same time, a block in the valve, with an inside channel and a side entry is forced into the open end of the conical member, and due to horizontal abutment faces on the container outlet and on the valve, a ring shaped space is left for the ink to reach the side entry and pass downwards. The valve has holes to permit air to enter the space between the outer cup shaped wall of the valve and the shouldered neck of the container.

Title: Laser beam welding using small dia beam - provides short welding times without altering props. near the weld
Inventor: MONTANARINI MARCO DR SC NAT
IPC: B23K26/32
Filed: 1974-10-12
Abstract: In a process for the welding together of two or more materials, each possessing special physical properties, the materials are melted by a laser beam at the desired junction so that the molten zones are mixed together, but the materials outside the junction retain their original physical properties. For welding, one or more elements which are not present in the materials being welded, or only present in a minor amt., may be mixed in the molten zone. To restrict the radial spread of heat, the laser is pref. operated in the transverse TEM. mode, and the molten zone is pref. 0.1mm dia. using operational times of ca. 1 msec. Prevents the formation of zones adjacent to the weld which have different properties to those possessed by the materials being joined, e.g. transition zones. The materials being welded are pref. spring- or magneic-materials, plastics, dielectrics, ceramics, or a combination of SmCO5 with iron. The additional element(s) may improve weldability or weld-strength, or prevent cracking, and are pref. Nb, Ti or Ta when an Fe/Ni or a Cr/Fe/Ni alloy is being welded.

Title: Ignition advance retard system - has bypass depression pipe with non-return valve to give improved ignition timing during acceleration phase
Inventor: GROPP KARL HEINZ
IPC: F02P5/10
Filed: 1974-10-19
Abstract: A depression opening in the carburettor air intake tube just above the throttle valve slow running position is connected by a pipe with a restrictor section to a diaphragm servo which is able to move the contact breaker plate in a clockwise direction to retard the ignition timing point and an anti-clockwise direction to advance corresponding to the degree of depression. The carburettor base is provided with a second depression opening and feed pipe which joins up with the servo feed pipe and contains a non-return valve which only opens in the event of a strong acceleration in order to bypass the restrictor section to give a more favourable ignition timing during the acceleration phase, that is less advanced timing point.
