Title: New or improved vending machine for a material such as solid fuel
Inventor: SMITH WALTER ARTHUR
IPC: G07F13/04
Filed: 1959-02-02
Abstract: 876,360. Coin-freed vending apparatus. CHARROLD Ltd. Jan. 28, 1960 [Feb. 2, 1959], No. 3640/59. Class 27 A coin-freed machine for vending material sucn as solid fuel comprises a hopper 1 from which the material is conveyed by a belt 12 to a weighing receptacle 17, the conveyer belt being manually operable by a handle 6 on insertion of a coin which causes engagement of a clutch 35, 36. An inserted coin passes through a tester 23 and falls into one of several pockets 45 on a disc 44 geared to the clutch shaft 33. On rotation of the disc by the handle 6, the coin engages a cam element 46 pivoted at 47 and moves it outwards so that linkage 48, 49 engages the clutch. The link 48 has a releasable connection 60, Fig. 6, with a link 61 parallel to it and, as the clutch engages, spring- loaded linkage 62, 63 moves the disc 44 laterally on its shaft so that the coin, which initially engages a lateral extension at the beginning of the cam surface, is pulled over into line with the remainder of the cam surface. The receptacle 17 fills until, by means of rods 18, it pulls down a tipping scale on a weighing machine 19 and trips catches 21 against stops 21 <SP>x</SP> so that the receptacle tips its contents into an opening 10 and into a sack which may be obtainable from a coin-freed device incorporated in the casing of the machine. A cam member 67 on one of the rods 18 operates linkage 66, 65 to disengage the connection 60 and the disc 44 moves laterally to its initial position, releasing the coin to a box 70, and so allowing the cam element 46 to return and disengage the clutch 35, 36. If the hopper is empty, the coin remains between the disc 44 and the cam 46 until it reaches the end of the latter, from which it falls to a return outlet 8.
Patent GB-764149-A (GB)
Title: Improvements in or relating to production of chlorides
IPC: C07C43/12
Filed: 1955-02-08
Abstract: The invention comprises a process for the production of alkyl and polyalkylene oxyalkylaryl and -alkyl-chlorides by the action of thionyl chloride on alcohols, including aromatic alcohols and polyalkylene oxy-alcohols, in presence of finely-divided carbon under anhydrous conditions.  In examples, the following chlorides are prepared by the action of thionyl chloride in presence of 1-4 per cent of finelydivided carbon on the corresponding alcohols: <FORM:0764149/IV(b)/1> C12H25(OC2H4)3Cl, cetyl chloride, octadecyl chloride, octyl chloride, <FORM:0764149/IV(b)/2> <FORM:0764149/IV(b)/3> C8H17(OC2H4)3Cl, C16H33(OC2H4)3Cl.  The carbon acts both as catalyst and as de-colorising agent.  Other alcohols specified for conversion to chlorides are those where the hydrocarbon chain is of 8-18 carbons, and aromaticaliphatic alcohols with one or more alkyl groups of 6-15 carbon atoms and 1-18 ethoxy groups, with optionally one or two propoxy groups.

Title: The production of hollow articles from plastic materials
Inventor: SPEYER DENIS NICHOLAS
IPC: B29C49/04
Filed: 1960-02-02
Abstract: 887,538. Blow-moulding hollow articles. IMPERIAL CHEMICAL INDUSTRIES Ltd. Jan. 13, 1961 [Feb. 2, 1960], No. 3741/60. Class 87(2). Hollow articles are produced from organic thermoplastic materials by extruding a tube of such material vertically downwards, nipping the tube at a predetermined length between two mould sections which form the top of a four part hollow mould, severing the tube above the nip and moving it by means of the said mould sections, so that the mandrel is inserted into the inner end of the tube segment, closing the remaining mould sections 5 and 6 around the tube, thus nipping it around the mandrel, and applying fluid pressure, generally air, through the mandrel to expand the tube into contact with the mould. Preferably the inner mould sections 5 and 6 are cored so that a fluid, usually water, can pass through and cool the moulding before it is removed from the mould. Preferably the upper mould sections move vertically downwards after nipping the tube so that the tube is in a relatively taut condition when it is severed by either a double edge or a rotary tyre knife. The apparatus of this invention is suited for large scale production by employing a number of moulding units with one extrusion die and either moving the moulds laterally immediately after the lower mould sections are closed or mounting the said mould units on a turn table.

Abstract: Artificial wood is manufactured from raw materials of vegetable origin and binding agents based on natural and/or synthetic resins by a process characterized by (a) that the degree to which the raw material is broken down is a degree short of reduction of the material to individual fibres, and (b) that the broken down material is first impregnated in a condition of dryness such as is attained by drying in the open air, with an aqueous emulsion of the selected resin, then moulded, and then dried and hardened under pressure, preferably of 1-20 kilogrammes per sq. cm. and at an elevated temperature preferably between 100 DEG  and 200 DEG  C.  The emulsion may be of colophony, of urea-formaldehyde or phenol-formaldehyde resin in the "A" stage of condensation and preferably contains 50 to 10 per cent by weight of resin.  The vegetable materials may be wood shavings, sawdust or straw.

Title: Improvements relating to visible card indexes, sectional maps and the like
IPC: B42F17/18
Filed: 1930-02-07
Abstract: 347,773. Filing papers &c. ; maps. PEEL, A., 46, Beaufort Gardens, Brompton Road, London. Feb. 7, 1930, No. 4184. [Classes 146 (i) and 146 (ii).] In a device for filing or arranging index cards, cloth patterns, samples of paper, or map sections in overlapping formation, a series of backing members are employed adapted to be assembled together in predetermined relationship, adjacent members being secured together by the pin for hinging the card &c. holder thereto. In one form, Fig. 3, each backing member 20 has a pair of eyes 21, 22 struck up therefrom and slots 23, 24 punched out immediately below the eyes. A series of backings are assembled together by inserting the eyes on one member 20 through the slots of the adjacent member. Each card is slotted at 28, 29 so as to engage lugs 26, 27 on a flat strip 25 beaded on one edge 30 so as to hold slidably a hinge-pin 34. The beading 30 is cut away to fit over the eyes 21, 22 so that by sliding the pin axially it engages the eyes and locks the parts 20, 25 together. In another construction, Fig. 9, each backing member 40 has oppositely directed half-hinge lugs 41, 42, 43 which abut against recesses 44, 45, 46 in the lower edge of the member 40 immediately above it. The slots 28, 29 on each card engage looped parts 52, 53 on a hinge-wire 50 which passes on opposite sides of the lugs 41, 42, 43 to hold adjacent members 40 together and has cranked parts 51 to prevent its endwise movement. The central lugs 41 may be formed as complete eyes and the hinge-pins may be permanently secured thereto. If desired, the wires 50 may be cranked externally of the lugs 42, 43, in which case additional lugs are stamped up from the members 40 to prevent endwise movement of the wires when they are turned through 180 from the position shown in Fig. 8. In a further modification, the hinge pin tends to force the adjacent members 40 apart. For this purpose, the lugs 41, 42, 43 point in opposite directions and the pin passes on the opposite sides thereof to those shown in Fig. 8. The members 40 are held from separation by the provision of lugs on the edge of one member which engage slots near the edge of the adjacent member. The cords are creased along lines 29a so as to ensure that they lie flat against one another. The loops 52, 53 on the hinge wire may be bent in the form shown in Fig. 10 and, where envelopes are used instead of index cards, serve to hold down the flaps. As the backing members are never greater in transverse width than the cards carried thereby, the width of the carrying tray or drawer is determined only by the width of the cards and thus no space is wasted.

The chains 21 are mounted on pulleys 23, 24, which may be rotated by a handle 29 through bevel gearing 30. The temporary receiver is also provided with flexible strips 31 so as to form a lattice work which may be moved above the table 2.
