Title: Finished velvet fabric - with variable pile height produced on warp knitting machines
IPC: D04B21/02
Filed: 1970-11-11
Abstract: Velvet fabric with finished cut pile without auxiliary shrinking process and with pile height varying from 1-6 mm. is produced on warp knitting machines in that during each knitting cycle the pile guide bars are reciprocated twice through the lanes of the suprajacent needles and tufting needles and allowing the two underlays and overlays to take place in such a manner that during the first overlay only the pile thread guide rails are disposed over the tufting needles for carrying out during the return stroke the first underlay whose height determines the length of the pile loop, whilst during the second return stroke the second overlay of the guide rails over the knitting needles takes place jointly with the canvas rails and the second underlay can then be carried out in known manner on all the warp knitting machines whilst the needle bar is in its lowest position.

Title: X-ray generator tube radiation time control - uses feedback phase information from tube drive to control dosage time
Inventor: SOEDER EICKHARD
IPC: H05G1/38
Filed: 1971-12-20
Abstract: An X-ray generator timing circuit uses feedback information concerning the relative phases of the current and voltage supply to the generator to control the "on" time. The generator tube is fed from the mains from the extra high voltage winding (3) of a transformer (1) on which a heater winding (5) is also supplied. The primary current is supplied via a contact (7) controlled by a drive circuit (7) which is, in turn, under the control of a timer circuit (11). A phase detector and comparator arrangement (13, 14, 15, 16) detects the phase relationship between current and voltage in the transformer primary. Where the generator produces radiation, a phase shift is detected, and this triggers the timing network (11) via a rectifying and integrating combination (19, 20, 21). When the timer runs down, it switches the entire circuit off via the drive control (7) and main contact (8).

Title: Fusing refractory oxides in electric furnace - provided with tuyere introduced through discharge aperture
Inventor: CLISHEM THOMAS ALOYSIUS
IPC: C04B35/657
Filed: 1971-07-27
Abstract: Fusing refractory oxides in an electric furnace contg. a tiltable crucible and provided with a cooled tuyere for oxidising gases, which can be temporarily introduced through the discharged aperture and tightly seal the latter, is improved in that in the upright position some melt is added to or left in the crucible whilst more charge is being added with the heating switched on, so that the level of the melt rises but still does not reach the discharge aperture; then the tuyere is introduced through the discharge aperture and pref. air or oxygen is introduced above the melt surface; subsequently, the crucible is tilted until the melt covers the discharge aperture stopped by the tuyere; air or oxygen is further introduced; finally, the crudible is tilted back to the upright position so that the melt level sinks again below the discharge aperture and the gas supply is discontinued, the tuyere is withdrawn and the crucible is tilted again to pour the melt out. This method is applied in the prodn. of ceramic articles by casting, which gives products superior to sintered articles. Introduction of the tuyere through the discharge aperture simplifies the structure of the furnace (no permanently sealed hole is needed) and the problem of cooling the tuyere; the life service the of the latter is extended.

Title: Colour anodising process control - by photodiodes and phototransistors scanning workpiece and reference plate
Inventor: LECHER ELMAR
IPC: C25D11/14
Filed: 1973-03-14
Abstract: The dying operation in an Eloxal colour anodizing process is controlled by measuring the thickness of the coloured layer on the workpiece continuously within the bath by a photo-diode and a photo-transistor used as transmitter. The light flashes from the photodiode are reflected by the workpiece and their reflections are received from the phototransistor.

Title: Anti-skid wheel brake - reinforced by electro-magnetic brake which senses wheel locking by reducing current
Inventor: HAGEDORN GERHARD DIPL-ING
IPC: B60T13/74
Filed: 1973-08-08
Abstract: The conventional wheel brakes are reinforced by electromagnetic brakes fitted to at least two wheels. The rotating wheel forms the rotating permanent magnet while the stator is magnetised through battery powered windings. The induced current is shorted through a shunt whose value is such that it provides a constant current until wheel blocking nears, when the current drops rapidly. The dropping current is also used to modulate the mechanical braking effect, and acts as a simple type as anti-skid braking control.

Title: Load compensator for super charged compression ignition engine - has speed change sensor to adjust air and fuel feed
Inventor: UNO MOTOHIKO
IPC: F02D29/06
Filed: 1974-03-25
Abstract: The engine turns a generator which is provided with a revolution counter sensor whose contacts close when the generator speed falls below the required value. The signal influences the air feed by means of a magnetically operated throttle flap, the air pressure intake unloader valve and the fuel volume delivery rack. When a sudden load occurs, the regulator responds to the speed sensor to close a circuit which activates the solenoids to feed additional air and fuel to the engine. The additional air comes from either a super charger or a compressed air storage tank.
