Filed: 1933-07-28
Abstract: 423,363. Endless-belt conveyers. BRITISH JEFFREY-DIAMOND, Ltd., Stennard Works, Wakefield, and TINSLEY, H., Cap Frehel, Castle Hill, Sandal, both in Yorkshire. July 28, 1933, No. 21316. [Class 78 (i)] The upper side members of the casing are of V-shape or similar form, and are arranged to impart a shallow troughlike formation to the belt. The side members 12, Fig. 5, are provided with slots 17 and lugs 18 to receive idler rollers 19 which may be tapered to assist in imparting the desired formation to the belt. The rollers are rotatably mounted on spindles 20, the ends of which are slotted or formed with flats to engage with the lugs 18. The side members may be interchangeable so that the higher wall 12<b> may be located at either side. Supports 16, Fig. 3, are secured to the members 12, and are hooked over the upper edges of the side plates 13 of stools. The transverse member connecting the plates 13 is slotted to receive the supports 16. Idler rollers for supporting the return run of the belt may be provided on the stools, or the transverse members may be shaped to allow the belt to travel smoothly over them. The side members 12 of the tail end intermediate section are fitted telescopically in a trough 24, Fig. 1, connected to the tail end frame 26. A rubber covered scraper 29 of V-formation engages the lower run of the belt and directs spillage towards the sides. At the tail end the belt may be passed round a spider, Fig. 10, the arms of which cause it to assume such a form that material does not accumulate on it.

Title: An improved escapement for clockwork mechanism
IPC: G04B15/10
Filed: 1926-08-31
Abstract: 258,247. Wirz, A. Sept. 8, 1925, [Convention date]. Escapements.-A pendulum raises a weighted lever which coacts with an escapement lever controlling the action of a ratchet escape wheel which is rigid with a star-wheel controlled by a pin which oscillates with the escapement lever. The pendulum rod 1 has an arm 2 with a jewelled plate 3 adapted to raise a flexible steel wire 8 on a screw 7 carried by the weighted lever 4. This lever is supported at one end 6 and at the other end carries a stud 10 and catch 11. In its lowermost position the lever 4 rests on a stud 9. Coacting with the parts 10, 11 is an escapement lever 13, counterweighted at 14 and having a head 20, the curved end of this escapement lever co-operating with a ratchet escape wheel 15 rigid with a star-wheel 16, the rotation of which latter is controlled by a counterweighted arm 17 operated by a pin 18 on a disc 19 which rocks with the lever 13. Starting with the parts in the full-line positions shown, as the pendulum swings to the left the lever 4 is raised and the escapement lever 13 moves counterclockwise. As soon as this commences the arm 17 releases the star-wheel 16 which, together with the ratchet wheel, rotates clockwise; in the meantime the curved end of the escapement lever has moved inwards to engage the next tooth of the ratchet wheel. Subsequently, the ratchet wheel moves the escapement lever clockwise until the latter moves behind the catch 11 and is arrested by the stud 10. This arreste the ratchet and star wheels until the pendulum again raises the lever 4. The head 20 and catch 11 have their opposing surfaces jewelled, that of the head 20 being the harder. The wheels 15 and 16, when released, are rotated clockwise by a main-spring and actuate the ordinary clockwork mechanism to the hand.

An earclip comprises a U-shaped member 10, Fig. 1, dimensioned to receive loosely between its arms the lobe 11 of an ear 12, the outer arm 13 of the member 10 being provided with jewels or ornaments 14, 15 and the inner arm 16 being bent downwardly at its upper end to form a hook 17 which provides a fulcrum for the offset end 19 of a lobe-clamping member 23 which is apertured so that it can be threaded upon the upper part of the arm 16 and pressed in the direction of the other arm 13 by the upward pressure of a helical spring carried upon the arm 16 within a tubular housing 18. The lower end of the spring 20 abuts against a widened part 21 of the arm 16, at right-angles to the part of the latter shown in Fig. 4, and the upper end of the spring bears against the upper end 18a of the housing 18. The part of the member 23 that engages the lobe of the ear is wider than the other parts of the member, and the lower portion 25 is bifurcated so that it can straddle the part of the arm 16 below the housing 18.

Title: Improvements in or relating to nuclear reactors

Filed: 1964-05-26
Abstract: 1,016,113. Reactors. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. May 26, 1964 [May 31, 1963; March 24, 1964], No. 21741/64. Heading G6C. A fluid-cooled nuclear reactor core structure comprises at least one group of parallel fuel elements on a polygonal lattice, and control units each comprising control rods (coarse, fine or emergency) of the same cross-section and spacing as the fuel elements, said core being characterized in that the control rods maintain a constant cross-section to the coolant during their operation, and in that deflectors placed in coolant flow channels defined by adjacent fuel and/or control rods cause the coolant to flow in a helical path. The constant control rod section is required in order that the moderation pattern of the core may be undisturbed by control functions. The required effect may be achieved by means of solid rods having extensions of low neutron absorber of identical cross-section, by placing conventional rods within tubes or behind partitions such that they do not displace coolant, by using fixed tubes containing a liquid whose neutron absorption can be varied, or by varying the liquid level in a tube of a neutron absorber. The deflectors are in the form of helicallytwisted strips of low neutron absorber (e.g. stainless steel) placed axially between groups of fuel elements, and may be either of constant width, or of variable width so as to penetrate between the fuel elements (Fig. 5, not shown). The helices are of opposite hand in adjacent channels. When partition walls are used to separate the control rods and coolant, these may be joined to the deflectors by grids to form a rigid structure; such a structure will help in locating and supporting the fuel and control rods.

A tube drawing machine comprises dies 9, 10 through which the tube is drawn and helically wound on to a rotating drawing block 1 against which it is radially deformed by a roller 12 to maintain its shape after ejection from the drum. After the leading end of the tube has passed through the dies it is gripped by a gripper 4 which is retracted into a recess 5 in the block 1 and the roller 12 is brought into contact with the tube. The separation between the block 1 and the roller 12 may be varied by a handwheel 18 which moves a slide 15 to which the roller is connected by a lever linkage 13. The roller is brought into the operative position by means of a pressure actuated cylinder 14. The formed coils are ejected downwardly from the block. By deformation of the tubing in the above manner, Fig. 3b (not shown), helical coils of substantially constant diameter can be obtained for various metals, e.g. copper, brass, steel, aluminium, simply by varying the separation between the roller and the block. Sample results obtained using the above apparatus are given. The formed coils may be fed by a conveyor on to the swift for successive drawing processes.
