Title: Improvements in or relating to remote control systems
Inventor: FRIEDLANDER ERICH SIEGFRIED
IPC: B66B3/02
Filed: 1955-09-19
Abstract: 809,415. Electric control systems. GENERAL ELECTRIC CO. Ltd. Sept. 18, 1956 [Sept. 19, 1955], No. 26737/55. Class 40 (1). A system in which an indicating member is required to follow positional charges of a controlling member, e.g. a depth indicator for use with a mine winder, comprises a selsyn system and a self-balancing bridge responsive to misalignment of the rotor shafts of the transmitter and receiver of the selsyn, in which out-ofbalance current operates means to disconnect the transmitter from the receiver and to rotate the latter until the misalignment is eliminated, whereupon the selsyn connections are restored. In Fig. 1, the rotor of the transmitter 1 of a selsyn drives the rotatable arms of potentiometers 3, 4, 5 so that the speed of 3 > the speed of 4 > the speed of 5, and the rotor of the receiver 2 drives the arms of potentiometers 6, 7, 8 at speeds corresponding to those of potentiometers 3, 4, 5, respectively, potentiometers 3 and 6, 4 and 7, 5 and 8, respectively being connected to form three bridges which are balanced when the transmitter and receiver rotors are in alignment. Gross misalignment causes an unbalance current in the least-sensitive bridge, potentiometers 5 and 8, which energizes a relay 12 to open selsyn contacts 13 and to energize a reversible motor 14 which drives the receiver rotor to reduce the error. De-energization of relay 12 connects power (by switching means not shown) via energized relays 11 and 10 in succession to continue to drive the motor 14 until the most sensitive bridge, potentiometers 3 and 6, is re-balanced, when relay 10 falls back, disconnecting power from the motor 14 and closing contacts 13. To prevent the motor 14 being driven in the wrong direction consequent upon a sudden change of polarity of the arm of potentiometer 3 or 4, relays 15 and 16 are arranged to pull up when the error signals in their respective circuits exceed a predetermined fraction, e.g. one half, of the bridge supply voltage, thus reversing the polarity of the supply to the motor 14; alternatively, an arrangement as shown in Fig. 3 may be substituted for each of the two more-sensitive bridges in Fig. 1, each potentiometer 27, 28 comprising two half-sections 27a, 27b and 28a, 28b, respectively. A contact arm 31 is ganged to the rotating arm 27<SP>1</SP> of potentiometer 27 so that during one half revolution of the arm 271 from the midpoint of section 27b to the midpoint of section 27a, a relay 33 will be energized, and during the other half-revolution 33 will be deenergized, as shown, the supply voltage then being applied between potentiometer terminals 40, 41 and 44, 45, respectively. When relay 33 pulls up, contacts 34, 35, 36 open and contacts 37, 38, 39 close, transferring the supply to terminals 42, 43 and 46, 47.

Abstract: 1299486 Fluid filter; centrifugal separator DONALDSON CO Inc 5 June 1970 [5 June 1969] 27285/70 Headings BID BIT and B2P An inward-flow annular filter element 20 and screen 47 are cleaned by a jet of reverse flow fluid from a nozzle 64 which travels along a continuous helical path to cover the whole interior of the screen. The reverse flow fluid is delivered into rotary fluid motor 40 (Fig. 6, not shown) through which it passes to a housing 52 which is rotated by the motor about fixed shaft 37. A vertical bar 55 secured to housing 52 engages square-sectioned block 60 which carries the nozzle 64, causing it to rotate. Block 60 carries a follower (71) which engages in an endless track formed by left and right-handed helical grooves 70, joined at their ends, in shaft 37, and the block and nozzle are thus caused to follow the helical path. The fluid passes from housing 52 through coiled hose 75 to block 60 and nozzle 64. Fig. 7 (not shown) illustrates a slightly different arrangement in which the cleaning fluid passes down a central bore through shaft 37 to a rotary housing (52') at its lower end, and thence through a vertically extensible hose (75') of bellows construction to the block and nozzle. The filter has an array of inlet apertures 14 bridged by screen to remove coarse particles, through which fluid enters housing 10 past vanes 15 which induce centrifugal separation by rotating the fluid. Particles thus separated and those backwashed from the filter element pass through aperture 30 into annular channel 26, whence they are periodically removed via outlet 27. Filter element 20 is of pleated paper, with end caps and support screen 22. Screen 47 serves to support motor 40. The housing cover 13 is secured by nut 45 on the cleaning fluid inlet line. Filtered fluid outlet 12 has a bead to facilitate attachment to a hose. Prior art description refers to a nozzle comprising two concentric tubes, one with a helical slot and the other with an axial slot, which rotate relative to each other and also describe orbital motion about a filter element being cleaned, the nozzle opening formed-where the slots coincide describing a helical path.
