Title: Vacuum power circuit breaker
IPC: H01H33/664
Filed: 1974-03-26
Abstract: 1445475 Vacuum circuit breakers MEIDENSHA K K 26 March 1974 [2 April 1973] 13356/74 Heading H1N A vacuum circuit breaker having both contact rods 22, 24 connected through the end plates by flexible bellows 32, 34 has the fixed contact rod 22 fixedly supported by a discshaped support member 48 which is in turn rigidly connected to a stationary support by means of one or more projections 50. The support member 48 also has one or more holes 52 into which projections 54 on the end plate 14 project thus allowing relative axial movement between the fixed contact rod 22 and the envelope to absorb contact-making impact, but preventing relative twisting between them, which might damage the bellows. Stops abutting the outer face of support member 48 may be screwed on to the ends of the projections 54 where they emerge through the apertures 52 (Figs. 4 and 5, not shown) to prevent any axial pull on the contact rods during handling resulting in outward movement of the rod relative to the envelope. To prevent relative twisting between the moving contact rod 24 and the envelope a sleeve 56 is fitted into the aperture of the end plate 16 and splined onto the contact rod by means of complementary teeth and grooves.

Title: Improvements in textile speed frames
Inventor: FRANCE JOSEPH
IPC: D01H1/30
Filed: 1962-04-06
Abstract: 970,634. Driving arrangements for spinning &c. machines. T.M.M. (RESEARCH) Ltd. April 4,1963 [April 6,1962 ], No. 13376/62. Heading D1D. [Also in Division G3] In a programmed control system for a textile speed frame the spindles and bobbins are driven by step-by-step motors controlled by pulses derived from a pair of tracks on a magnetic tape. Each track is produced by recording the output of an oscillator which is amplitude modulated by switching the bias between two levels. The bias switching during recording is effected by a commutator comprising a shaft 11, Fig. 1, carrying four axially spaced commutator rings 12-15. The rings 12,13 are interrupted to form semicircular segments 16-19 and rings 14,15 are continuous. The interconnection of the rings is such as to insert a direct connection in a grid-bias circuit to an oscillator 24 during one half of a revolution of the shaft 11 and a predetermined direct bias voltage during the other half-cycle. Recording. A record of a package build-up cycle is prepared by employing a conventional speed frame having a constant speed drive to the spindles and a variable speed drive to the bobbins which compounds, through a differential gear, the constant speed drive with a variable speed drive from a variable ratio cone drum unit, or, alternatively, a special machine of conventional type having one or a small number of spindles. The output of the differential gear is arranged to drive the commutator to produce one track in the tape and subsequently the second track is prepared by recording the variable speed of the cone drum unit. Alternatively, two commutators are employed and the tracks recorded simultaneously. Reproduction. A textile speed frame, Fig. 2, adapted to be controlled by the programme tape has spindles driven by a constant speed motor 25 and bobbins and lifter rails driven by electric motors 26 and 27 controlled by the tape 28. The tape is fed from a spool 29 past two reproducing heads 30, 31 to a take-up spool 32. The tape is driven from the constant speed motor 25 by a roller 33 and a pressure roller 61 and the tape speed is adjusted by altering the axial position of roller 33 which is tapered Each head 30, 31 controls a corresponding step-by-step motor 26,27 amplifiers 34, 40 and thyratron speed control units 35, 41.

Filed: 1958-05-01
Abstract: 904,943. Synchronizing arrangements. BRUSH ELECTRICAL ENGINEERING CO. Ltd. June 30, 1959 [May 1, 1958], No. 13915/58. Class 38 (4). An alternator 13 is connected to bus-bars 14 by closing contacts 15a when the voltages of the alternator and the bus-bars are approximately in phase opposition. The synchronizing operation is initiated by closing contacts 16a, 16b, 16c whereupon the transformers 18, 19 receive voltages from the alternator 13 and bus-bars 14 respectively. Relay 17 is thus energized to close contacts 17a and a current will flow in relays 24, 25 which are so. arranged that relay 24 is energized whenever the current therein is above a value corresponding to a phase difference between alternator and busbars volts of 11 degrees, whilst relay 25 is energized only when the sum of the alternator and bus-bar volts is greater than either the alternator or bus-bar volts alone. Thus after the closure of contacts 17a relay 24 operates and contact 24a opens whilst contact 24b closes. When the alternator and bus-bar volts approach synchronism relay 25 operates to close contacts 25a whereupon a relay 26 is energized to close a contact 26b and a selfmaintaining contact 26a. When now the alternator and bus-bar volts are within 11 degrees of synchronism relay 24 drops out thereby closing contact 24a. Relay 15 is thereupon energized, closing contacts 15a to parallel the alternator 13 to the bus-bars 14, contacts 15b, 15c opening to de-energize the transformers 18, 19. The alternator 13 can be connected to the bus-bars 14 when these are " dead " by means of contacts 27a, 27b.

Filed: 1930-05-08
Abstract: 354,364. Haymaking. NICHOLSON, A. C., Trent Iron Works, Newark-on-Trent. May 8, 1930, No. 14110. [Class 6 (iii).] In a side-delivery rake or like machine of the type in which a number of rake bars extend obliquely across the machine, and are carried at their opposite ends by rotary flyers so that the tines of the rakes are maintained vertical, the rotary flyers being mounted on a supplementary frame that can be raised or lowered, the rear leg of the supplementary frame is so connected to a part behind the rear flyer as to permit of the radius of movement of the rear leg being varied during the raising and lowering of the frame. The machine is carried by rear wheels B driving an axle A from which main frame bars C extend over the rake bars E to a swivelling forward wheel D. A rear flyer G is mounted on a spindle V carried rotatably in a gearbox J pivoted on the axle A of the spindle being driven from the axle. The front flyer His rotatably mounted on a peg W fitted into a bracket K secured to the forward leg L<1> of the supplementary frame L. The frame L is carried by crank-arms M, N, mounted on a cross-shaft O adapted to be rocked in bearings Q, R, by a hand-lever P. The forward leg Ll is guided in its upward movement by a pin riding in an arcuate slot in a bracket U secured to the main frame. The radius of the arc is such that the front flyer H moves through part of a circle of which the centre is as far behind the front flyer as the centre of the axle A is behind the rear one, thus permitting the tines of the rakes to be maintained vertical through the lifting or lowering movement. The rear leg L<2> of the supplementary frame is connected to the cam J through links Z and a smaller amount of lift is given to this leg by making the rear crank N shorter than the forward one M. To adjust the distance of the rakes from the ground the frame L may be attached to the cranks, as shown in Fig. 5. The frame-bar passes through an eye M<1> on a bolt that may be adjusted in position by nuts M<2>, M<3>. The crank may be secured by a pivot M<5> to the fitting on the rod O.
