Title: Improvements in or relating to arrangements for feeding threads
IPC: A47F13/04
Filed: 1958-02-06
Abstract: 870,149. String' &c. cutters. RASCH, W., [trading as RASCH SPEZIALMASCHINENFABRIK, WILHELM]. Feb. 6, 1958 [May 20, 1957], No. 41705/60. Divided out of 870,148. Class 30. [Also in Group XVII] A device for presenting threads to the suspension string attachment means of Specification 870,148 comprises an intermittently rotatable pulley 14, having gaps 37 bridged by the thread 11 the thread being guided in a groove 16 in the pulley periphery and clamped at its free end by one of a pair of bell crank levers 17, 18. The levers are moved to clamp the thread against stops 26, 27 by a slide 28 acting on oblique surfaces 32, one lever gripping the thread while the other releases it. The pulley rotates 180 degrees with the lever 18 (as shown) gripping the thread. A cutter arm 38 pivots towards the pulley and engages the slide moving it to the right so that the lever 18 releases the thread and the lever 17 clamps it. The cutter 39 then severs the thread so that the portion bridging the upper gap 37 is free to be withdrawn.

Abstract: 910,902. Nuclear fuel elements. GENERAL ELECTRIC CO. Ltd. Dec. 2, 1960 [Dec. 8, 1959], No. 41749/59. Class 39 (4). A structure for supporting a nuclear fuel, element within a graphite sleeve 9 comprises four identically-shaped members, each formed from strip metal, e.g. zirconium, and having a body portion 1 and two spacer portions 2, 2<SP>1</SP>, each spacer portion 2 being secured to a spacer portion 2<SP>1</SP> of a neighbouring strip member and engaging a positioning slot 10 in the sleeve 9, and a fixation member 13 of cruciform shape, the four arms 14 of which each project through a slot in one of the body portions 1 of the strip members. A hole 15 in the fixation member 13 enables the member to be affixed to a fuel element by means of a fixing collar on a stem projecting from the base of the fuel element down through the hole 15. In order to prevent rotation of the fuel element within the support, a serrated locking ring 11 is provided which engages splines on the fuel element can. The spacer portions 2, 2<SP>1</SP> are secured together by welding to I-section pieces 5 and T-section pieces 6 so as to provide locating slots 7, 8 to engage cut-away portions on each of four swirler vanes attached to the fuel element can. In a modified construction (Fig. 4), the strip members are more simply shaped in respect of the body portions 21 and the locking ring 22, serrated as before, is of circular section, being keyed to the support by means of cutaway slots engaging each arm of the fixation member 23. Each of these arms also projects through slots in two adjoining strip members, as shown. The adjacent arms of the strip members are spaced from each other by square spacer plates 24 and further rigidity is obtained by spot-welding the arms together at points 26, one of each pair of arms being dimpled at such a point. The ends of the strip members are curved back as shown at 27 so as to provide larger bearing surfaces on the seatings in the graphite sleeve.

Abstract: 943,033. Axle connections for laminated springs. N. RANGER. Dec. 6, 1960 [Jan. 4, 1960], No. 42028/60. Heading B7D. A vehicle axle is rigidly secured at one end 11 to one longitudinal semi-elliptic spring and at the other end 10 is resiliently secured to a second longitudinal semi-elliptic spring. Fig. 3 shows a resilient mounting for a spring comprising an annular rubber bush 10B retained on axle 3A by two collars 10C and held within a split housing 10, the two parts of which are secured to each other and to the spring by U bolts 10A. Alternatively, the spring and axle end may each be secured to a block of resilient material. Longitudinal location of the axle is provided by a pair of radius rods below the springs. As applied to twin axles, Fig. 4, the resilient connections 14, 17 are on opposite sides of the vehicle and the adjacent ends of the springs on each side are connected by a lever 21 pivoted to the chassis. To avoid loss of traction when a rear wheel 24 drops into a depression 25 and raises through lever 21, the front driving wheel 28 on that side, a pressure exerting element 29 may be fitted to the end 27 of the lever which may take the form of an hydraulic or pneumatic ram or a screw jack and may be arranged to be operated automatically or manually.

Title: Data processors

IPC: G06F9/318
Filed: 1965-10-06
Abstract: 1,117,027. Digital electric data processor. WESTERN ELECTRIC CO. Inc. 6 Oct., 1965 [7 Oct., 1964], No. 42350/65. Heading G4A. A digital electric data processor comprises a store, an instruction word register, means responsive to a word held in said register to control both a first operation and a second operation on data held in the store and means responsive to an instruction word specifying an implausible second operation for inhibiting the second operation and performing instead a third operation. As described (Figs. 1 and 2) a data processor normally has a combined operation of read and shift, write and shift and transfer and shift. In the particular embodiment, a word of 21 bits is shifted requiring in the shift or combined shift instruction a 5-bit portion specifying how many places the word must be shifted. Thus an instruction giving shifts of 22 to 31 positions is implausible and can be decoded to perform a different operation. In the embodiment a detector (71) connected to the shift instruction data decodes a shift of 22 in an implausible read-shift order and inhibits the shift register selector (16). Data is read from memory into a register selected by the read part of the instruction and into a further preselected register. The detector (71) enables an AND gate (72) so that data fed from memory under the read command and set to a register selector to be fed into a register according to the command, also by-passes the register and is fed to the preselected register.

[Also in Division B7] A structural component is made by sandwiching helically wound resin impregnated glass fibre tubing between outer skins. The tubing contains inner inflatable tubing which may be used to store liquids or which may be filled with foamed resin. In the example illustrated in the Figure an aerofoil is made by covering a core 1 with a resin-impregnated fibre layer 2, e.g. a fibreglass laminate, winding a fibre resin tube 3 containing an inflated tube 7 on to the covered core, deflating tube 7, applying an outer fibre resin layer 5, e.g. a fibreglass laminate, and inserting the assembly thus formed into a mould to cure the resin. During this step the tube 7 is reinflated to force the windings of the tube 9 together. The tube 7 is then deflated and core 1 removed. By varying the compression force of the mould and the degree to which the tube 7 is inflated the tube 3 is hardened in varying cross-sectional shapes (see Figures 3-5, not shown). In a second embodiment (see Figure 2, not shown) a series of covered individual cores are wrapped with fibre resin tube and covered by a single outer layer. Longitudinal reinforcement is interposed between the tube and the outer layer.
