Abstract: 944,516. Nuclear fuel elements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 19, 1962 [March 6, 1961], No. 8177/61. Heading G6C. In a polygonal helical type fuel element 1, i.e. one having helical heat transfer fins 4 intersected by longitudinal splitter fins 5a, 5b, 5c, 5d of greater radial depth, each splitter fin has in the region of its outer edge a flange, all the flanges 6a, 6b, 6c, 6d extending in the same rotational direction. The fuel element shown in plan view in Fig. 2, against the longitudinal coolant flow, has the fins 4 of right-hand helix and the flanges 6a, 6b, 6c, 6d extending in the same direction, i.e. clockwise, in close proximity with the wall of the fuel channel 2. The splitter fins 5a, 5b, 5c, 5d divide the channel 2 into zones A, B, C, D, causing intermixing to occur between the coolant in between the fins 4 and the coolant in each zone, also causing the coolant in each zone to vortex (as indicated by the arrowed flow loop 9 shown in zone A), to give improved heat transfer characteristics. The flanges deflect the vortexing coolant away from the wall of the channel 2 in the regions of the splitter fins and thereby reduce the passage of coolant from one zone to another, thus reducing the tendency of the fuel element to rattle. In zone A, for example, the flange 6a deflects the vortexing coolant (as indicated by arrow 10) away from the channel wall in the region of the splitter fin 5a.

Abstract: 487,085. Stapling. BOSTON WIRE STITCHER CO. March 19, 1937, No. 8207. Convention date, March 20, 1936. '[Class 89 (iii)] A stapling tool is provided with means whereby the driving stroke of the driver may be effected by either a single stroke or a succession of strokes of an operating lever, the mechanical advantage of the lever also being increased in the latter case, to adapt the tool for operating on hard or resistant workpieces. The tool, which is adapted to be held and operated by one hand, comprises a frame 3 with a finger hole 9, an anvil blade 13, a magazine 20, and an operating lever 70. The frame is adjustably secured to a base member 10 carrying the blade 13, and the magazine, which is pivoted in the frame at 21, comprises a channel member 20, Fig. 13, with flanges 22, a pair of staple-supporting rails 23, a pusher 24, and a gate 28 permitting loading from the front. The gate, Fig. 16, has lugs 29 pivoting in slots 30 in extensions 27 of the member 20, and is held locked, with recesses 31 engaging lugs 32 on the rails 23, by a spring 45. When locked, the gate causes the staple driver 35 to release a pawl 37 which, when the gate is open, holds back the staples s. The driver is operated by a reciprocating slide 40, an extension 43 of which engages a hole in the driver and is engaged by the spring 45 to hold the driver raised to an extent limited by a yoke member 46 connected to the extensions 27. The slide 40 is operated by a lever 50 which is pivoted at 54, is raised by a spring 61, and includes a member 52 having shoulders 57, 58 and an extension 60. The hand-lever 70 operates the lever 50 through one of two pawls 86, 87. If soft material is to be stapled, the pawl 86 occupies the position shown, with its nose 92 engaging the shoulder 57, so that a single stroke of the lever 70 imparts its full stroke to the driver 35. If hard material is to be dealt with, the pawl 86 is turned clockwise to inoperative position. Depression of the lever 70 then causes the pawl 87 to engage the shoulder 58, imparting part of its stroke to the driver. While the driver is held against return by a pawl 101 engaging a rack 100, the lever 70 is released and again depressed. The pawl 87 now engages the projection 60, imparting the remainder of its stroke to the driver. The rack 100 then passes below the pawl 101, so that the driver is free to rise under pressure of the spring 45 when the lever 70 is released. The spring 45 causes the magazine to swing down into engagement with the work on the anvil 13 when the lever 70 is first depressed. The lever 70 normally is held in raised position by a spring 79.

Abstract: 600,244. Pulse modulation. STANDARD TELEPHONES & CABLES, Ltd. May 5, 1944, No. 8598. Convention date, Aug. 24, 1942. [Class 40 (v)] The timing of short pulses is varied in accordance with a signal wave by combining that wave with a wave of fixed frequency in a fullwave rectifier circuit, the sharp peaks or cusps of the rectified wave being utilized to derive the pulses, In Fig. 1, a sine-wave source 111 is connected through amplifiers or limiters 110, 112 to a transformer 116 with a divided secondary, the outer terminals of which are shunted by a condenser and are connected to the cathodes of rectifiers 114, 115, the anodes of which are earthed through a load resistance 117. Between the inner terminals of the divided secondary is connected the secondary of a transformer 121, the primary of which is fed from the signal source 122. A battery 121<1> with its mid-point earthed is connected between the secondaries of the transformer 121, thus biassing the cathodes of the rectifiers 114, 115 in opposite senses. When there is no signal, the voltage across the load 17 has the form shown at Db in Fig. 6, whilst the effect of positive and negative signal voltage is shown respectively by the curves Dc, Da. The cusps y, y<1>, y<11> are thus displaced along the time axis in accordance with the signal. A limiter 123 clips off the pulses at the level indicated in Fig. 6 and they are used to modulate .a carrier source 125 feeding an aerial 126. The pulses may also be passed through differentiating circuits (Figs. 5a, 5b, not shown), The sinewave source 111 may be replaced by a multivibrator followed by an integrating circuit giving a symmetrical triangular waveform (Fig. 4, not shown). The bias battery 121<1> may be arranged to bias one only of the rectifiers (Fig. 2, not shown), and the rectifiers may be of the metallic type. In a further modification, the rectifiers are of the triode type with input applied to the grids and output taken from the anodes. The signal voltage may be disconnected from the jack 128 and applied through the jack 129 to the amplifier 110 so as to modulate the amplitude of the wave applied to the rectifiers. Specifications 509,820, 511,222, 521,139, 523,575 and 529,648 are referred to.
