Title: Improved control mechanisms for automatic flat knitting machines
IPC: D04B11/00
Filed: 1967-03-17
Abstract: 1,110,800. Knitting-machines. H. STOLL, G. STOLL, E. STOLL, E. STOLL, J. STOLL, A. STOLL, R. E. STOLL, and M. STOLL. 17 March, 1967 [18 March, 1966], No. 12634/67. Heading D1C. In a flat machine the members controlling the extent of the carriage traverse are selectively displaced by spindles driven from the carriage drive via magnetic clutches. The control mechanism for the members comprises a shaft 2 oscillated from a reciprocating drive chain 9 via gears 5, 8. A electric contact cam 13 is rotated between set limits by a friction clutch 6-7 at each change in the direction of rotation. A contact 19 selectively actuated by the pattern mechanism is engaged by cam 13 and actuates electro-magnetic clutches on the main drive shaft 2 or upper auxiliary shaft 27. Engagement of clutch 3-3' rotates spindle 44 via chains 41.2 to adjust the position of the yarn guide limiters, carriage reversal cams and lock adjustment pins at one end of the machine. Engagement of clutch 3-3" effects similar adjustment at the other end by rotation of spindle 44'. When clutches 31-32/32' on the auxiliary shaft 27 are engaged the spindles 44, 44' are returned to a set, zero position through a higher transmission chain drive. The spindles are held in their set positions by engagement of moveable clutch parts 38, 38' with a fixed part 37.

Type-carriages.-Relates to flat-platen machines comprising a type-carriage movable for letterspacing on a carriage which is movable for linespacing. (i) The line-spacing carriage 5 shown in rear elevation and bottom plan in Figs. 2 and 3, consists of front and rear bars 12, 13, and side bars 11 formed with integral brackets 14 on which are mounted bars 8, 9 carrying adding-devices and controlling-means therefor respectively. Preferably, the brackets 14 and an intermediate bracket 77 secured to the bar 13 are formed with slotted lugs 73 and sleeves 75 receiving supports 74, 76 for the bars 8, 9 respectively (ii). The line-spacing carriage is supported on the usual rails by means of ball-bearing rollers 16 mounted on the bar 12, and rollers 18 carried by the line-spacing shaft 15 which is mounted on ball-bearings 19, Fig. 16, in the brackets 14. The bars 12, 13 are provided with ballbearing guide-rollers 17 engaging the rails. The front rollers 16, 17 are covered by a shield 67. Sheet-clamping arrangements.-A spring-urged plate 65, Fig. 3, for smoothing the sheet on the platen is mounted on the front bar 12 of the line-spacing carriage 5. The plate is preferably provided with ears which are pivoted to brackets 68 on the shield 67, and are formed with a stoplug engaging the shield, and a lug engaging a spring. Line-spacing mechanism.-The rocking members of the line-spacing mechanism, instead of being mounted on the line-spacing shaft, are mounted on a stationary sleeve. The mechanism shown in Figs. 2 and 16 comprises a knurled wheel 34 secured to the line-spacing shaft 15 and co-operating in the usual manner with a dog 33 which is mounted on a rocker 32<a> and is operated by a rocker 31. The rockers are mounted on a hub 30 which is revoluble on a sleeve 28 secured to one of the brackets 14. A collar 32 secured to a hub is connected by a link 43 to a crank on the shaft 45 operated by a linespacing lever. The knurled wheel is swaged on a hub 35 secured to the shaft. The line-spacing regulator 38 is mounted on the hub 35. Carriage-brakes.-A brake comprises a retarding-member co-operating with a frictionally mounted member on the line-spacing shaft.

Title: Improvements in or relating to retaining devices for fuel elements in gas-cooled nuclear reactors
Inventor: ROBINSON GEORGE EDWARD
IPC: G21C5/06
Filed: 1954-05-06
Abstract: 794,981. Nuclear fuel elements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. May 4, 1955 [May 6, 1954], No. 13314/54. Drawings to Specification. Class 39(4). In a gas cooled reactor, a mechanical retaining device prevents movement of the fuel elements through the full duct by the thrust of the coolant gas current. The uranium fuse is in rod form, enclosed in aluminium and supported on a graphite carrier slidable in the horizontal fuel duct formed in the graphite bricks of the pile. The elements are hooked together to form a string within the duct and the retaining device engages the outer surface of the pile. A thrust upon the free end of retaining device, tending to discharge the fuel elements out through the far end of the duct, compresses a spring and releases the retaining catch at the pile surface, thus leaving the elements freely movable along the duct. The retaining catch consists of three members each of which engages the pile surface separately, an initial thrust causes two members to disengage simultaneously and a further thrust releases the third member. In one embodiment the third member also serves to lock the complete catch mechanism in the disengaged position.

[Class 80 (iv)] The guard 5, Fig. 1, to a circular revolving knife 1 of a slicing machine is mounted on a swivel bracket 8 which is mounted on a vertical post 4 on the bracket 2 of the machine. The bracket 8 may be turned by an adjusting screw 12, which is threaded through a lug 13, Fig. 2, on the bracket 2 and has connection with an arm 14 on the swivel bracket 8, so as to vary the width of the gap between the guard 5 and knife 1. A scale on the knob 18 of screw 12 enables the gap to be always adjusted to be slightly greater than the slice thickness regulated by the feed mechanism. A second embodiment automatically adjusts the width of the gap to be slightly greater than the thickness of slice being cut. The guard 5, Fig. 5, is mounted at its lower end on a support 25 having guide rods 26, 27. The rod 26 carries a roller 31 co-operating with a cam 32, the position of which is altered as the feed-mechanism device 22, 23, 24 is adjusted, so that the width of the gap between guard and knife is varied.
