Title: Circular textile machine - has electromagnetically operated needle selector and activator
Inventor: ALLAVENA GUIDO
IPC: D04B15/78
Filed: 1973-03-20
Abstract: A circular textile machine includes a pair of pref. pivotal actuator rods which have hooked upper ends for engagement with a hooked lower end of the needle, and a pref. pivotal selector plate is positioned with its upper end between the lower ends of the actuator rods and is movable under the action of an electromagnet to engage and pivot onr or other of the actuator rods, such that the actuator rod engages and actuates the needle. The actuator rods are pref. of different lengths so that they each move the needle to a knitting position at a different height for producing a pattern knit. Pref. the electromagnet produces a constant magnetic field around the actuator plate, and a current of a selected polarity is passed through the actuator plate according to a control programme to cause the actuator plate to pivot in one direction or the other to engage one or other of the actuator rods, the machine is used particularly for knitting stockings.

Title: Refractory lining for rotary kiln - with prepd. high strength blocks of complicated shapes
Inventor: STRUZIK ERICH
IPC: F27D1/00
Filed: 1973-04-28
Abstract: Refractory lining with prepd. blocks of complicated shapes having high strength is applied to a rotary kiln with planetary cooling tubes in the region where the two are connected by ducts of changing dimensions. The prepd. parts have embedded in their outer surfaces threaded pins onto which threaded nuts can be tightened to hold them in place, making it easy to dismantle a worn lining and reassemble a fresh lining easily, thus reducing time. The threaded pins are assembled to fix the lining at a controlled spacing from the outer shell.
Patent DE-2327777-A1 (DE)
Title: Running and gating system for mould cavities - restricting flow out of downgate reduces turbulence and eliminates filter grids
Inventor: LIEBIG EDGAR
IPC: B22C9/08
Filed: 1973-05-30
Abstract: This system is esp. suitable for cast-iron, non-ferrous metals and non-metallic melts, and is designed to ensure that a head of molten metal forms in the downgate. In the case of cast-iron, the downgate ends in an annular gap leading to a well which supplied the runner. There should be a fixed ratio between the cross sections of the gap:well:filling system of 1:1.3:1.2. The cross-section of the filling system (runners and gates) is calculated by normal methods and thus the desired cross-sections of the gap and well can be derived. By restricting (but not stopping) the flow of molten metal into the mould, and maintaining a head in the downgate, the amt. of inclusions and gas picked up by the molten metal is reduced, and the need to use a filter grid in the bottom of the downgate is eliminated.

The rounded body and front and side surface rollers deflect objects colliding with the car either to one side or over the vehicle roof.
Patent DE-2354075-A1 (DE)
Title: Vehicle hydro-mechanical transmission - has a lower hydrostatic drive synchronised with an upper hydromechanical drive
Inventor: NYMAN BENGT E
IPC: F16H47/04
Filed: 1973-10-29
Abstract: The transmission has a first hydraulic stage connected to the input shaft and a second hydraulic stage connected to the output shaft. The stages are connected together by pipes. Pressure operated adjusters for the output of one hydraulic stage alter the rotation of the output shaft relative to the input shaft. A main regulator valve controls the adjusting fluid. An accelerator loads the main regulator valve with a predetermined preload and operates the engine throttle. According to engine speed a pressure signal is led to the main regulator valve which is opposed to the manual preload to achieve a transmission ratio which controls the engine speed.

Title: Rotary vane piston engine - has rotating burners with shaft driving air compressor, for use with low-octane or liq. fuels
Inventor: ABRAMOWSKY HORST
IPC: F02G1/02
Filed: 1973-12-28
Abstract: Rotary vane piston engine for motor vehicles, ships, or generators has no reciprocating parts and requires no Pb-containing high-rating fuels, i.e. for all gaseous or liq. fuels and without a high octane number. Combustion occurs in the rotating burners, which with their shaft simultaneously drive the air compressor. Internal cooling is by injection of water, which after condensation is re-used.

Patent DE-2422295-A1 (DE)
Title: Coil-ends joined for continuous rolling of sheet and strip - automatic centering, cut-off, flash butt welding and grooving
Inventor: SEYMOUR PHILIP
IPC: B23K11/04
Filed: 1974-05-08
Abstract: The end of the strip being rolled is moved backwards over a clamp and welding cheeks until it meets the guide-edge in the lower part of flying-shears; it is then centred and a looping device takes up any bow in the strip; a strip-support roll then drops so that the strip rests on the lower welding cheek. The end of the new coil of sheet or strip is fed in from the other (i.e. the entry) side of the machine and is treated in a similar manner, both ends being in position. Clamps outside the two pairs of welding cheeks clamp the strips and move the two edges slightly away from the guide in the shears, which then cut the edges and move out of the gap between two heads which carry the welding cheeks. When the flying shears have left the gap, one head moves towards the second, stationary head and a flash butt weld is made in the normal way. The strip then moves through a deburring unit and a groove-stamper. The cycle is completely automatic due to using servo-mechanisms etc. which can be operated by electric, mechanical, hydraulic or pneumatic means.

Patent DE-2438340-A1 (DE)
Title: Inhibiting erasure of cassetted magnetic tape - by detector receiving information from cassette depending on tape movement direction
Inventor: STAAR THEOPHIEL CLEMENT JOZEF
IPC: G11B15/06
Filed: 1974-08-09
Abstract: Magnetic tape erasure is prevented in a cassette in which the tape can run in either direction from one spool to another during recording or play-back. The cassetted tape can be driven by either spool. The cassette has in one edge an aperture with a spring which can be removed so as to prevent recording from taking place. The absence of a spring is sensed by a projection of a slide which works in conjunction with another slide at 90 deg. to it, to operate a lever and contacts, which release a signal and stop the tape. A similar arrangement of slides operates in respect of another aperture with spring in the same edge of the cassette. Instead of being purely mechanical, the arrangement may also be electro-mechanical.
