Patent GB-236629-A (GB)
Title: Improvements in conveyors particularly for materials used in wire drawing
IPC: B21C47/26
Filed: 1924-04-07
Abstract: 236,629. Kelly, J. R. April 7, 1924. Pickling; tinning.-Articles such as coils of metal rod for use in wire drawing which are fed in a single series to a bath for preparatory treatment are divided into several series by a distributing device, conveyed through the bath by a corresponding number of helical conveyers and recollected into a single series in which they are. spaced apart automatically. The bath A may contain acid, the bath B may be a chamber for washing with water, and the bath C may contain any special solution. The coils drop down a shoot 1, Fig. 1, into a distributing device, Fig. 3, comprising pivoted arms 2, 3, 12, 13, 14 and shoots 10, 20, 30. The arms 2, 3 are secured to a shaft 4 and the other arms to a shaft 23. An arm 9, Fig. 4, fixed to the shaft 4 is connected by a rod 25 to an arm 24 free on the shaft 23. A cam 15 fixed on the shaft 23 co-operates with a spring catch 18 fixed to the arm 24. The first coil of the series is deflected by the arm 2 on to the arm 3 which tilts and allows the coil to pass into the shoot 10. The movement of the arms 3, 2 is limited by the partition 8 and edge 6, respectively. The rotation of the arm 9 causes the end of the catch 18 to slip off a stationary inclined plane 22 on to the cam. The next coil falls on to the arm 12 and turns it through an angle of 90‹ during its passage to the shoot 20. The movement of the arm 12 moves the arms 13, 14 and cam 15 through the same angle in a clockwise direction but does not move the arm 9 &c. The catch 18 is now on one of the four lowest parts 15A of the cam. The next coil is deflected by the arm 13 on to the arm 14, which tilts as before, and in turning rotates the cam 15 and catch 18 in an anticlockwise direction and so resets the distributing mechanism. The shoots 10, 20, 30 deliver to inclined helical conveyers A<1>, A<2>, A<3>, the upper ends of which are above the acid in the bath A so that the coils may drain before entering the collecting device, Fig. 5, for transfer to the conveyer b. The passage A' is closed by a sliding door b<9> provided with a pin b<8> which engages a cam groove b<7>, Fig. 7, formed in a plate b<5> attached to the conveyer b. During each revolution of the conveyer the door is withdrawn and a coil allowed to fall. Entry of the coils is facilitated by making the first half turn of the helix b' of greater pitch than the remainder. The part of the conveyer to the left of the partition B<1> is surrounded by a coil B<2> of water pipe arranged to spray the articles. After leaving the bath B the articles are admitted one at a time by mechanism similar to that shown in Fig. 7 to an inclined conveyer c in a bath C. The inclined conveyers are supported in hanger bearings, Fig. 9, comprising stirrups 40 carrying rollers 41. The shoots, distributing device, and conveyers are made of hard wood.

Patent GB-573456-A (GB)
Title: Production of vinyl cyanide
Filed: 1944-05-12
Abstract: A process for the production of vinyl cyanide, which comprises reacting acetylene with hydrogen cyanide at a temperature above the boiling point of vinyl cyanide and in the presence of a catalyst for the reaction, includes the step of condensing the vapours of vinyl cyanide resulting from the reaction and acidifying the condensate. The crude product may then be stored for a considerable time without decomposition occurring and better yields of the pure vinyl cyanide are obtained on distillation.  To render the crude product acid, any of the common inorganic or organic acids such as sulphur dioxide or sulphurous acid, sulphuric acid, hydrochloric acid, nitric acid, chloric acid, phosphoric acid, acetic acid, oxalic acid, propionic acid, lactic acid, tartaric acid or glycollic acid may be used, as well as salts whose aqueous solutions have an acid reaction, for example sodium dihydrogen phosphate, zinc sulphate and aluminium chloride.  Preferably, non-corrosive acidic materials are employed. Water may be added to the acidic material but preferably in amounts not more than 10 per cent to 15 per cent of the acidic material utilised.  Acids such as sulphuric or nitric acids should be added as dilute solutions.  The preferred amount of acid used should be such that a water extract obtained by shaking 10 volumes of the acidified condensate with 25 volumes of water at room temperature will have a pH below 4.6.  The acidic material should preferably be introduced intermittently or continuously into the condensing apparatus though it is effective when added to the condensate receiver.  If a gaseous acidic material is employed, it may be added to the gaseous reaction products at some point in the system before condensation has taken place.  In an example, acetylene and hydrogen cyanide are reacted over a catalys consisting of sodium cyanide supported on activated carbon and the condensed reaction products collected in receivers containing glacial acetic acid.  On subsequent distillation the recovered vinyl cyanide amounted to 66 per cent by weight of the condensate.  A similar experiment in which the acid was omitted gave a recovery of only 10 per cent.  German Specification 559,734 is referred to.

Abstract: 807,572. Making pallets and pallet covers. WHEELING STEEL CORPORATION. March 23, 1956 [Sept. 6, 1955], No. 9115/56. Class 83 (2). [Also in Groups XVII and XXX] A pallet, or a cover for a palletized load, is built up from a number of die-pressed portions which overlap and interfit. The pallet shown in plan in Fig. 7 is built up of a centre die-pressing 11, side die-pressings 8, and corner die-pressings 2 which overlap as indicated by the broken lines and are secured together by spot welds 18. Each pressing includes a foot 4, 4<SP>1</SP>, 4<SP>11</SP>, and channels 5, 9, 10, 12 which take into one another. Since all the channels extend to the margins of the pressings the three dies employed for the pressings may be employed to form pressings for pallets of different sizes. After the pressings have been welded together deeper channels 20 are pressed in them and channelsection pressings 15 are welded in the channels 20. A peripheral flange 6 (Fig. 8) is pressed into an inwardly directed lip 19 by two forming operations. The cover for a palletized load, shown in Fig. 15, is formed by spot-welding together two pressings similar to that shown in Fig. 12 and then pressing further channels 28 and forming the flat peripheral flange 23 of Fig. 12 into an inwardly-directed lip 29, Fig. 15. The peripheral groove 24 of Fig. 12 is formed by two applications of a die which forms a partial groove 22, as shown in Fig. 9, so that the die may be used with pressings of different size. The channels 25 of Fig. 12 are then formed and portions 26 of the channel 24 on one of the two members to be secured together are widened so that the corresponding portions of the other member will fit within them. Specifications 807,571 and 807,573 are referred to.
