Title: Apparatus for positioning jacks in slotted pattern wheel rings according to a predetermined pattern
IPC: D04B37/04
Filed: 1973-06-19
Abstract: 1430678 Knitting machines SINGER CO 19 June 1973 [15 Sept 1972] 28963/73 Heading DIC A device for setting pattern wheel jacks comprising a patter-bearing carriage 26 indexable relative to a marker and a support 64 for a pattern wheel ring 66 which is indexed when the carriage is indexed. The carriage supports a rotatable roller 34 around which a pattern card can be entrained. A rack 24 fixed to the carriage engaged a pinion 40 indexed by a ratchet 44 and pawl 46 at the dictates of a solenoid 50. The pattern wheel ring 66 is registered by pins 73, 74 on the support gear 64, which is rotatable on a fixed pin 72. Jacks 70, Fig. 2, are pivotally mounted in each slot 68 of the ring. In the embodiment shown the ring is indexed by an actuator 94 raised into a slot, and then moved tangentially of the ring. Movement of the actuator is initiated by energising a solenoid simultaneously with carriage solenoid 50. The actuator 94 is fixed to a member 100 slidable in a plate 104. The plate is movable relative to a fixed part of the device. A lifting plate 128 is pivoted at 130 on plate 104 and can lift the member via a pin-and-slot connection 142, 144. Solenoid-actuated slides 182, 192 carry cam-faced actuating members 160, 166 which engage pins 164, 170 on the lifting plate. If slide 192 is driven into contact with pin 170 the plate is pivoted far enough to raise the actuator sufficiently to lift a jack 70. Pivot ing of the plate releases a locking lever 150 permitting a screw 178 on the slide to push the plate 104 against spring 116. Movement of the plate and actuator tangentially of the ring indexes the same. As the ring rotates jacks lifted by the actuator are moved into an inactive position by cam 288, Fig. 2. Movement of slide 182 merely indexes the ring. Solenoids actuating the respective slides are energised by an operative selectively depressing switches 280, 282, Fig. 3, depending on the pattern in formation. The solenoids are arranged in parallel, and in series with solenoid 50. A master device may be connected to one or more slave units to set jacks in the same or mirror-image fashion in extra rings. In an alternative arrangement the jacks are set manually.

The point at which link 10 joins arm 6 is such that it describes an elipse one part of which is a near circular arc centred on the other end of link 10, hence during this part of the cycle no motion is transmitted. The second link motion has a gear sector 13 which drives a gear 16  interconnected with sun gear 17 of the differential. An alternative arrangement is described, Fig. 11 (not shown) with a different linkage between link 10 and the gear sector. The eccentric disc 4 is bolted to a gear on the comb cylinder shaft by an arcuate slot to allow adjustment. The link 14 to the gear sector may also be adjustable.

Abstract: 947,715. Nuclear fuel elements. NUCLEAR POWER PLANT CO. Ltd., and A. E. I-JOHN THOMPSON NUCLEAR ENERGY CO. Ltd., [trading as NUCLEAR POWER GROUP]. Aug. 21,1961 [Aug. 26, 1960], No. 29498/60. Heading G6C. A fuel element comprises a member 1 of an oxidisable nuclear fuel such as uranium located in a closed container 2 along with a member 5 of a material, e.g. zirconium alloyed with small amounts of titanium or aluminium, which is more readily oxidisable than the fuel member 1 and which when oxidised due to leakage of coolant into the container changes its volume to an extent sufficient to produce a detectable leak in the container 2 before a predetermined degree of oxidation of the fuel member 1 takes place. As shown in Fig. 1, the more readily oxidisable member 5 is screwed into the end of the container 2 which is sealed by an end cap 3 joined to it by a weld 4. If a small leak occurs in the container 2, end cap 3 or weld 4, coolant, e.g. carbon dioxide, comes into contact with the more readily oxidisable member 5 and if there is some oxygen present in the coolant, the member 5 is oxidised and expands to produce a fracture in the weld 4 large enough to allow a detectable leakage of fission products. Alternatively (Fig. 4), the end cap 3 is screwed into the end of the container 2 and the more readily oxidisable member 5 comprises a number of discs located in a recess in the end of the fuel member 1 so that when oxidised, it expands to cause a fracture in the region 3a of the end cap 3. A threaded stud, or an internal thread on the end cap 3 (Fig. 3, not shown), enables a lifting or locating head to be attached to the element. A proportion of fertile or fissile material may be added to the material of member 5 to cause the generation of heat so that when the member 5 starts to oxidise the thermal insulating effect of the oxide layer will increase the temperature of the unoxidised portion and hence accelerate its oxidation. In this case, prior to use, the surface of the member 5 may be oxidised or provided with a coating of zirconium oxide or aluminium oxide.
