Abstract: 810,362. Coin-freed meters, GAS COUNCIL. Nov. 28, 1957 [Nov. 28, 1956], No. 36428/56. Class 27 In a coin-freed commodity meter, the credit indicator 13 is arranged so that it shows a zero reading before the supply cut-off device interrupts the supply, in order to ensure a greater likelihood that credit will be restored by the insertion of further coins before the suppply is cutoff from apparatus such as gas cookers and heaters employing permanently-lit pilot jets. The indicator may be of the normal drum type having slots 14 to form a gear track and having a scale on the rim visible through a window 12 on which is an index mark 20. The scale on the rim may extend from both sides of a zero mark or may be adjustable, either in the form of a long strip passing completely round the drum with its ends fitted through a slit in the drum and secured internally in resilient clips or in the form of a shorter strip 23 extending from the zero mark and either pasted to the drum or passing through a slit 24 at the zero mark and one of several slits 26, 28, the ends being secured by reslient clips 25, 27. The parts of the scale on different sides of the zero mark may be differently coloured. The cam 16 operating the cut-off may be as shown in Fig. 1 but, in place of or in addition to the usual means for effecting a warning shortly before the supply is cut-off, the cam may have, at the point corresponding. to the zero reading, a depression which operates a warning device or causes the supply to be partly reduced, either temporarily or up to the point where the rounded edge of the cut-off slot 19 begins increasingly to reduce the supply.

Patent GB-343624-A (GB)
IPC: C08G63/48
Filed: 1929-12-02
Abstract: A resinous composition is made by heating together a polyhydric alcohol, a polybasic acid or its anhydride, a drying oil acid, a natural acid resin and a non-drying oil, with or without a drying oil.  The ingredients are heated to a reaction temperature of about 240-260 DEG  C. until an initially soluble and fusible resinous mass is obtained, whose acid number is preferably less than 25, and which is convertible by heating and by oxidation to an insoluble, non-fusible state.  The compositions may be dissolved in solvents to form coating-compositions.  In examples (1) phthalic anhydride, glycerol, linseed fatty acid, rosin and castor oil are heated together to 240-260 DEG  C.  The resin may be dissolved in a mixture of a petroleum hydrocarbon of the naphtha type and an aromatic hydrocarbon such as benzol or toluol.  (2) phthalic anhydride, glycerol, linseed fatty acid, rosin, castor oil, and linseed and chinawood oils are heated together as before.  A solvent mixture comprising a high boiling solvent such as diethylene glycol monoethyl ether and a solvent of long boiling range such as coal tar naphtha, may be used to form a coating composition for insulating wires. Other natural acid resins such as congo or manilla gum may be used instead of rosin.  Such resins should have an acid number greater than 50.  The other ingredients may also be substituted by equivalents.  Specification 297,418, [Class 95, Paints &c.], and 306,924, [Class 2 (iii), Dyes &c.], are referred to.ALSO:A resinous composition is made by heating together a polyhydric alcohol, a polybasic acid or its anhydride, a drying oil acid, a natural acid, resin, and a non-drying oil, with or without a drying oil.

Title: Typebar Typewriting Machine
IPC: B41J7/94
Filed: 1967-08-11
Abstract: 1,151,158. Typewriters. INTERNATIONAL BUSINESS MACHINES CORP. 11 Aug., 1967 [15 Sept., 1966], No. 36883/67. Heading B6F. In a typebar typewriting machine wherein each typebar carries an upper case character and a lower ease character, means are provided to adjust the striking force of each typebar individually, and also to adjust simultaneously the striking forces of all the typebars, the simultaneous adjusting means comprising one striking- force controlling means operative when lower case printing is being carried out and another controlling means when upper-case printing is being effected. As shown, each type bar 11 with upper and lower case characters 13, 15 thereon, is pivoted at 17, and is connected by a link 21 to a lever 23 pivoted at 24 and carrying a pivoted cam member 25 having a toothed edge 27. Operation of a key causes the keylever to contact a lug 31 on a trip lever 33 pivoted on the lever 23, so that the lever 33 moves the cam 25 into engagement with a continuously-rotating resiliently-covered roller 29. Such engagement causes the typebar 11 to be rotated to effect printing and continues until a part 28 on the cam 25 strikes a knock-off finger 39, there being one finger 39 for each cam 25. The fingers 39 are mounted on a bar 35 and can be individually adjusted by screws 37 so as to vary the distances travelled by the cams 25 before they are disengaged from the roller 29, and thus to adjust the striking forces of the type bars 11. The bar 35 is pivoted at 41 and, when the machine is operating in lower case, rests on a cam 45 which can be rotated to adjust the bar position and therefore to adjust collectively the striking forces of the typebars. A second cam 43 is fixed to the spindle of cam 45, and the bar 35 carries a lever 47 which is aligned with the cam 43. When the machine is set for upper case printing, a link 51 is operated to rotate the lever 47 into a position where a part 53 thereof engages the cam 43 and raises the plate 35 from the cam 45 so that the plate is supported by the lever 47 resting on the cam 43. Rotation of the cam 43 now causes collective adjustment of the striking forces of the upper case characters. Since only a portion of the cams 43, 45 is employed for a range of settings, the cams may be rotated to bring other portions into use according to the media upon which typing is to be effected.

A tube of organic plastic material is extruded, then the tube is sheared from the extrusion head and simultaneously its sheared end is closed, the shearing and closing being effected by movement of one mould half. Then the said mould half, together with the sheared tube, is moved into contact with another mould half (which is stationary during the movement of the first mould half) to form a mould, and the tube is blown in the mould to form a bottle &c. Fig. 2 illustrates a procedure in which a tube 5 of polythene &c. is extruded downwardly from a head 2 over a blowing pipe 1. A mould half 4 carrying a knife 6 then sweeps across the underside of the head to cut off the tube, that side of the tube which is first severed being brought into contact with and sealed against the other side, which is then severed. At the same time the lower end of the tube is clamped against the blowing pipe by the lower end of mould part 4. The mould part, tube and pipe then move to the left towards stationary mould part 3, the tube being sealed at top and bottom, and the tube is blown to shape. Mould part 4 then retracts to the right, as shown in Fig. 4, the blowing pipe with the blown article retracts a little to the right to clear mould part 3, and a stripping ring 8 ascends to discharge the blown article and the neck waste. In a modification (Fig. 5, not shown) the mould part 4 has pins which penetrate the tube to prevent it falling away from the nozzle. Fig. 6 shows a modification in which two movable mould parts 4 are arranged back to back on a reciprocating member 14 and co-operate in turn with two fixed mould parts 3.
