Title: Improvements in or relating to rectifier installations
IPC: H02H7/125
Filed: 1957-07-26
Abstract: 852,137. Protective cut-out systems. SIEMENS-SCHUCKERTWERKE A.G. July 26, 1957 [July 26, 1956], No. 23763/57. Class 38 (5). [Also in Group XXXV] A rectifying arrangement with a protective device associated with each rectifier which renders inoperative all rectifier elements when a reverse fault current flow incorporates magnetic cores so disposed that upon flow of reverse current even of magnitude small compared with that of the forward current when the arrangement operates incorrectly, the magnetic state of the core through which the reverse current flows changes in a way which can be subsequently detected. Each rectifier or phase group of rectifiers, which may be mechanically or electromagnetically operated switches such as 1, gas discharge devices or germanium, silicon or other semi-conductor devices, has in series a conductor 4 passing through a saturable core 5 which is normally saturated by the forward current. The core has a magnetic characteristic such that the magnetism reverses when a small reverse current flows, and develops voltage in winding 6 to operate a device 7 which bridges switch 1 and other rectifying switches or disconnects the supply. The short-circuited path includes conductor 4 in core 5, so that its magnetic state is not disturbed if forward current starts before the switch opens. To find where the reverse current has passed the state of each core 5 may be tested by winding 8, or this winding may initiate a continuous signal at the time of reversal. To prevent operation of the protective device upon passage of the pulses of storage current in semi-conductor rectifiers, a relatively thin conductor 12 bridges conductor 10 in core 11, Fig. 2. To steeply rising storage current, conductor 12 exhibits impedance lower than that of path 10, but to the more slowly rising fault current, the impedance ratio is reversed. Alternatively core 11 may carry a winding connected to a capacitor which acts as a shortcircuited secondary winding when steep storage current flows.

Title: Improvements in and relating to control mechanisms for motor vehicles
Filed: 1923-09-24
Abstract: 230,875. Staude, E. G. Sept. 24, 1923. Controlling different functions by same lever; hydraulic transmission; setting and retaining devices for control- Ling-apparatus.- Comprises control mechanism in which the accelerator pedal, when released beyond the slowrunning position, brings into action a valve which controls a pump worked by the transmission gear between the clutch and the road wheels and so operates the clutch and brake pedals through the fluid pressure thus created. A gear pump is arranged in a casing 18 on the end of the change-speed gear box and comprises a gear wheel 21 rotated by the transmission shaft 9 and gearing with a loose wheel 25 rotating on a fixed eccentric 22. A fixed crescent-shaped member 26 separates the upper parts of the two gear wheels. The pump casing communicates through a port 29 with the gear case and the inlet 31 and outlet 32 are controlled by a sliding valve having a plunger 35 and two collars 37, 38. The accelerator pedal 61, when fully depressed, opens the throttle through an arm 65 and is provided with, a midway stop 62 which normally engages a plate 63 for the slow running position. When the pedal is moved sidewise to release the stop, the pedal rises to the position shown and acts on the valve 35 through a cam 60 and gearing 53, 52, allowing a spring 39 to force the valve to the position shown in which the outlet 32 is closed. The oil is thus forced from the pump into cylinders 40, 68 controlling the clutch and brake respectively through rods 70 acting on arms connected to the clutch and brake pedals. An adjustable relief valve is provided in an extension of the pump chamber. The brake cylinder 68 may be omitted, the increased pressure in the gear pump acting as a brake on the transmission shaft. In a modification two inter-engaging gear wheels of the change-speed gear are used as the oil pump, being enclosed in a separate casing within the gear-box.

In a thread-winding machine in which the winding stations are successively traversed by a trolley from which compressed air is directed towards elements of each station, e.g. threadtensioner, slub-catcher and a cup surrounding a cop supplying thread to a package being wound, and in which collected fly and slubs are removed by suction through a duct extending along the machine, the duct is provided at each winding station or each group of adjacent stations with a valve which is periodically operated to admit the fly &c. to the duct in correspondence with the trolley movement. The machine shown comprises at each station a traverse drum or guide 4 and a bobbin on which a package 5 is being wound, and rails 7 on which run the wheels 9 of a trolley 8, a slot 11 of which is engaged by a pin 12 carried by an endless driving chain 10 so that the trolley traverses the machine. The trolley carries nozzles 57, 58 directing air streams 59 and jets 60 downwardly to the outboard side of a row of stations and inwardly towards the packages 5 and downwardly to the inboard side of the row. A pin 21 is carried on an endless chain 20 in correspondence, synchronism and/or predetermined relationship with the trolley movement so that at each station (or group thereof) it co-operates with a spring-controlled arm 22 of a lever 23 to cause an arm 28 to actuate a stem 31 and open a valve 32, thus permitting communication between a suction duct 34 and a chamber 35. A collar 33 may be adjusted on the stem 31 so that valve 32 may be prevented from closing sufficiently to allow any fly in chamber 35 to be continuously removed by duct 34. As shown at the left-hand side of the machine, each chamber 35 has apertures 36, 37, in the paths of the stream 59 and jet 60 and adjacent a slub-catcher 38 co-operating with a pivoted flap 39 and a tensioning-cup 41, and communicates through a duct 44 with a cup-shaped member 47 surrounding a cop 46 supplying thread F to package 5. The lever 23 may be pivoted or allowed to pivot to open or close valve 32 by means of an overriding hand-lever 30 acting through a link 29 on arm 27. Apparatus shown at the right-hand side of the machine directs an additional stream of air towards slub-catcher 38 and cup 41 at each station and comprises a duct 48 also extending along the machine and supplying compressed air to a chamber 50 when a second valve 49 on stem 31 is opened with valve 32 ; chamber 50 leads to a nozzle 51 which is continuously oscillated by a drive from an eccentric 53. When the hand lever 30 is depressed (see above) it also engages an arm 39a to withdraw the flap 39 from operative contact with slub-catcher 38 to enable the thread F to be located in any required position.
