Filed: 1961-10-19
Abstract: 987,581. Spring power-storing mechanism. CROSSBOW-MOORE Ltd. Oct. 25, 1961 [Oct. 19, 1961], No. 37570/61. Heading F2S. [Also in Division F1] In a spring-driven motor for starting an I.C. engine, a steel spiral spring 13 having its inner end secured to the engine bed 14 is connected, at its outer end, to a drum 11 coupled to the engine crank-shaft 10 through an overrunning clutch 12. A pinion 17, fast on a shaft 18 journalled in a lever arm 20 hinged to the engine bed at 21, can be engaged with a ring gear 16 on the periphery of the drum 11 by rotating the arm 20, against the action of a light spring 23 and engaging its free end by a pivoted latch 24. A back stop 25, having its inner and outer members fixed respectively to the shaft 18 and to an extension piece 26 of the lever arm, allows the shaft 18 to rotate only in a clockwise direction in Fig. 1. In order to start the engine a crank-handle 19 on the end of shaft 18 is turned, clockwise to wind-up the spring 13 the back stop 25 preventing counter rotation of the crank-handle 19. When the spring 13 has been fully wound the latch 24 is tripped to release the lever arm 20 the drum 11 then flying back to imply an impulsive torque in a clockwise direction to the crank-shaft 10. If desired the outer end of the spring 13 may be anchored to the engine and the inner end fixed to the drum which, in this case, is located inside the spring the gear 16 either being displaced axially or positioned within the drum. In a modification, Fig. 3 (not shown), the spring consists of a torsion tube in the form of a stack of resilient cylinders, made e.g. of rubber, and bonded to alternate metal washers the stack being located by means of a rod passing through its centre. The resilient cylinders may be tapered in such a way that their radius increases with their axial length so that the shear stress is substantially the same at all radii.

Abstract: 1,187,166. Copolymerization. E.I. DUPONT DE NEMOURS & CO. 7 Aug., 1968 [15 Aug., 1967], No. 37774/68. Heading C3P. Hydrocarbon soluble copolymers of ethylene and an α-olefin are prepared in a hydrocarbon solvent at a temperature of from- 20 to +80 C. using a co-ordination catalyst in a reactor in which there are liquid and vapour phases, wherein ethylene is fed partly as a vapour and partly as a liquid, and the α-olefin is fed as a liquid, the ratio of liquid and olefin to liquid ethylene in the feed being high enough to form only solvent-soluble copolymer on contact with the catalyst. Preferably a small proportion of a non-conjugated diene is copolymerized. Part of the ethylene and α-olefin fed to the reactor may be unpolymerized monomers recycled to the reactor. The ethylene and α-olefin may be obtained in the liquid phase, and the mixture may be partially flashed to form a vapour phase having a higher ethylene/α-olefin ratio before being returned to the reactor. Preferably a vanadium containing co-ordination catalyst is employed. In the example, ethylene, propylene and 1,4-hexadiene are continuuously copolymerized in n-hexane, using a catalyst consisting of vanadium tris-(acetylacetonate) and diisobutyl aluminium monochloride.

Filed: 1976-09-13
Abstract: 1517866 Selective signalling INCOTERM CORP 13 Sept 1976 [28 Nov 1975] 37810/76 Heading G4H A branch banking system for on-line processing of banking transactions in response to customer-initiated and teller-initiated operations, comprises a central controller for maintaining transaction records and customer account data, and a plurality of remote branch controllers with a plurality of teller stations coupled to each, each teller station including a teller unit having an associated set of peripheral units each connected to storage means in the teller unit, each branch controller including means for polling in sequence its associated teller units to read out the storage means, the frequency of polling being sufficiently rapid that the entire polling period for all of the associated teller units is less than the minimum period for insertion of data from one of the peripheral units. The latter feature avoids data loss. The peripheral units are a teller function and numeric keyboard unit, a customer magnetic card reader, a customer I.D. number keyboard and a printer (status signals are input from the latter). These peripheral units provide parallel-by-bit inputs to the teller unit together with inputs to indicate new information. The latter inputs (except from the card reader) are scanned by a clock-driven counter which is stopped when it reaches an activated input. When the teller unit is polled, the new character from the peripheral indicated by the stopped counter (assuming it has stopped, i.e. a new character is available from one of the relevant peripherals) is gated to the storage means (a transmit register), whereas otherwise if the card reader is providing a new character the latter is gated to the transmit register. The transmit register also receives bits identifying the peripheral unit. The contents of the transmit register are sent serially-by-bit to the branch controller. The central controller, which includes a computer, polls the branch controllers. It also checks customer I.D. against the card data, establishes a record of the transaction, up-dates customer account data, and sends authorization and transaction data to a teller CRT display via the branch controller. It also controls the printer and lamps and an audible alarm via the teller unit. Each branch controller includes a minicomputer.

To enable S or Z twist yarns to be spun in an open end spinning device means are provided above the spinning chamber whereby fibres can be fed tangentially and selectively to the yarn forming surface in either direction. As show the lid of a spinning chamber is provided with channels 19, 20, each being capable of feeding fibres tangentially to the yarn forming surface in opposite directions. The fibres 21 coming from drafting means can be fed selectively to one of the channels by a guide member 22 which has guide channels 23, 24 and can be shifted between end positions determined by stops 25; thus to change the direction of twist the direction of rotation of the chamber is reversed and the fibres are fed down the other of the two fibre feeding channels 19, 20. The intermediate guide may have only a single channel and be movable between the two feed channels along an arcuate track, Fig. 6, not shown. In Fig. 3 not shown the chamber lid is rotatable so that the mouth of one of two channels therein can be brought into alignment with the fibres being fed from the drafting device. In Fig. 8 not shown the channels in the lid are joined by flexible tube to mouth pieces which can be brought selectively into a position to receive fibres from the drafting means. In Fig. 9 not shown a single channel in the lid leads to a curved slot in which there is a deflection which can be moved to deflect the fibres into the spinning chamber in either tangential direction.
