Title: Upset forging machines
Inventor: ETCHELLS HENRY FROST
IPC: B21J9/18
Filed: 1962-08-22
Abstract: 983,169. Linkwork. DAVID ETCHELLS (MACHINERY) Ltd. July 25, 1963 [Aug. 22, 1962], No. 32182/62. Heading F2K. [Also in Division B3] An upsetting machine has a reciprocating tool slide 11, a stationary work-gripping jaw 12, and a movable work gripping jaw 14 mounted on a slide 15 actuated through toggle linkage 16, main link 27, auxiliary link 28 and rocking lever 25, the auxiliary link 28 being normally almost in line with the main link and prevented from passing through a dead centre position and the arrangement being such that upon obstruction of the moving jaw 14, the rocking lever 25 will cause the auxiliary link 28 to pivot about its connection with the main link, Fig. 3, without operating the toggle linkage 16. The slide 11 carries a heading tool 13 and is actuated by connecting rod 18 and crank 17 driven through belt 22 by motor 20. The connected rod 18 is also coupled by link 24 to the rocking lever 25 such as to provide closed and open dwells for the gripping jaw. Auxiliary link 28 is normally held with its rocking lever pivot against an abutment 29 on the main link, Fig. 2 (not shown), and is also connected to the main link by a fluid cylinder and piston device 30, 31. Thus any obstruction of the moving jaw 14 causes the auxiliary link to pivot away from the abutment 29, Fig. 3, without operating the toggle 16. If the machine is stopped with the jaw 14 not in its fully raised position, the cylinder and piston device 30, 31 is operated to move the jaw into this position and also prevent its operation by the rocking lever. The latter may alternatively be actuated by a rotary cam on the crank-shaft.

Title: Improvements in and relating to the manufacture of briquettes from coal and other material
Inventor: JONES DAVID CLARENCE RHYS
IPC: C10L5/08
Filed: 1953-11-24
Abstract: 807,433. Making briquettes. COAL INDUSTRY (PATENTS) Ltd. Nov. 24, 1954 [Nov. 24, 1953 ; Feb. 12, 1954], Nos. 32592/53 and 4257/54. Class 87(2). Coal dust and other powdered material is briquetted by a method wherein the mass of particles under pressure is caused to undergo angular shear strain of predetermined magnitude and distribution. The angular shear strain is expressed as a mathematical formula and its characteristics in an experimental briquette are first found by dividing the briquette into layers and superposing them in a mould with deformable pellets, e.g. lead balls, arranged along the diameter of each layer. The mass is then briquetted and the ratio of maximum to minimum diameter of each pellet is measured, e.g. by X-ray photography, in the finished briquette, from which ratio the angular shear strain may be calculated. Thus the suitability or otherwise of the material may be decided experimentally and the conditions, e.g. of pressure, to produce the required angular shear strain may be found. Such conditions attend various briquetting methods described. The material 34, Fig. 2, may be compressed between oblique-ended plungers 31, 32 in a circular mould 33 with relative rotation between the mould and plungers. Further pressure may be applied to powder, already compacted in a mould 41, Fig. 4, by a second plunger with a projection from its face. A two-part plunger, Fig. 13, may be used, the inner and outer parts 22, 21 first moving together till a certain pressure is reached and the part 22 then continuing alone and pressing a protrusion of the material into the main body. An extrusion die of variable crosssection, e.g. a circle to an ellipse, may be used ; also double roller or ring roller briquetting presses. The mould may be hemispherical. whereby the surface of the brquette follows a line of distribution of equal angular shear strain. Binderless black coal briquettes may be produced by the invention, but the use of a binder is not excluded. The particles may be preheated. They should have no surplus moisture. Other powdered materials which may be briquetted by the invention are metals, e.g. aluminium and copper, and catalysts of the alumina silica type. Numerical examples are given. Specification 616,857 [Group XII] is referred to.

Title: Improvements in tobacco smoke filter element
IPC: A24B15/28
Filed: 1962-08-27
Abstract: A filter element capable of absorbing undesirable volatile constituents of tobacco smoke comprises a carrier base e.g. cellulosic or polymeric in character and in sheet, filament, or sponge-like form, including paper or finely shredded tobacco in which there is uniformly dispersed a finely divided adsorbtive material, e.g. active carbon and charcoal, silica gel, zeolites, chabazites, having adsorbed thereon a volatile smoke-flavouring agent, e.g methol, vanillin, benzaldehyde, spearmint oil, peppermint oil, clove oil, tardamon oil, ethylvalerate, capable of being selectively eluted from the adsorptive material in proportion to the amount of tobacco smoke passing through the filter element, the latter containing only adsorbed flavouring agent to obviate storage loss by volatilization. Adsorption of the flavouring agent to the adsorbtive material and incorporation of the latter into the carrier base may be effected by conventional techniques, e.g. as described in Specification 764,470.

Title: Mirror shock absorber device for a camera having a quick return mirror
IPC: G03B19/12
Filed: 1972-07-13
Abstract: 1384753 Reflex cameras NIPPON KOGAKU KK 13 July 1972 [15 July 1971]  32862/72 Heading G2A In returning from its displaced position to its normal reflecting position, at 45 degrees to the optical axis, the mirror 1 of a reflex camera displaces a double lever 5, 6, which brings a portion 15b of a rotatable member 15 into frictional engagement with the periphery 11a of a fixed cylinder 11, the arrangement thus acting as a shock absorber for the mirror. The mirror 1 is pivoted on a shaft 2, and Figs. 1 and 3 show the mirror urged by a spring 3 into its lower or view-finding position, when it is at 45 degrees to the optical axis. Two levers 5, 6 are mounted on a common shaft 7, lever 5 bearing against mirror 1 and lever 6 bearing against a fixed pin 10. Shaft 7 is journalled in a fixed cylinder 11  having a disc portion 11a at one end. A member 14 is rotatably mounted on cylinder 11, and the rotatable member 15 is pivotally mounted on member 14 by a pin 16. A spring 17 is attached at one end to a fixed point 18 and at the other end to member 15, thus drawing member 15 anticlockwise. This causes a bent-over extension portion 15a of member 15 to bear against lever 6 and urge it also anti-clockwise, so that it abuts against pin 10 and lever 5 abuts against mirror 1. In this position there is a slight clearance between portion 15b and the periphery 11a of cylinder 11. When the camera shutter is released the mirror 1 is momentarily pivoted upwards to allow the exposure to be made, and then returns to the position shown under the action of spring 3. This causes it to impact lever 5, so that levers 5 and 6 are momentarily driven clockwise. Lever 6 engages against portion 15a so that member 15 is also pushed clockwise and portion 15b engages against and slides frictionally over peripheral portion 11a. This frictional engagement absorbs the downward force of mirror 1, after which spring 17 draws the mechanism back to the normal rest position illustrated.

Abstract: 940,817. Knitting-machines. SCOTT & WILLIAMS Inc. Sept. 13, 1961 [Sept. 25, 1960], No. 32879/61. Heading D1C. A knitting machine having means for severing a splicing yarn as it is fed to or withdrawn from the needles, has means for holding the resultant severed yarn ends and further means for removing simultaneously from the holding means a plurality of the severed ends. The holding means comprise members 48, 56 which may be pressed together, to clamp a yarn, by a leather element 98 secured to one end of a lever 96 pivoted at 92 and pressed downward by a spring 108, and an auxiliary clamping member 84. A lever 94 is rockable by a rod 80 to lift the lever 96 against the biasing spring, and is provided with a pin loosely engaging a slot in member 84. Splicing yarn withdrawn by finger 16 from the needles passes, as the cylinder rotates, between members 48, 56, around pin 110 and passes under the member 84, lever 96 being in a raised position to withdraw the element 98 but not to raise the member 84. On further movement of the cylinder the yarn is carried under the pneumatic extraction tube 36 and passes into a notch in a dial cap ring 23 to be severed between the notch edge 46 and one of the fins 28 of the dial. When the splicing yarn is reintroduced by finger 16 the yarn end is carried by the needles beneath the member 48 to enter a second notch having a cutting edge 42, and is severed as before. These operations are repeated until at the end of the splicing operation there will be an accumulation of cut yarn ends lying together and all beneath tube 36. Lever 76 is then released, the cut ends being then clamped beneath member 56. At a convenient time after the completion of the splicing suction is applied to the tube 36 and lever 76 is fully operated to raise members 98 and 84 to allow the suction to withdraw the yarn ends.
