Abstract: 1,215,608. Selective printing; photographic type-composing; re-usable writing surfaces. ING. C. OLIVETTI & C. S.p.A. 13 March, 1968 [25 May, 1967], No. 12109/68. Headings B6F, B6P and B6W. A device permitting temporary inscription of matter such as computer output comprises a temporary inscription carrier 1 having a dark coloured surface at least partly covered by a thin layer of light-coloured paste unaffected by air, an impression member 8 carrying a raised character 10 which when pressed against the carrier 1 displaces paste to reveal an area of the dark-coloured surface in the shape of the selected character, and erasing means such as rollers 12, 6 for evening out the layer of paste. The carrier 1 may be in the form of an endless band or a drum. Temporary image carriers; repeatedly usable writing surfaces.-The carrier 1 may comprise a synthetic rubber or darkened stainless steel band covered with a thin layer of white paste formed of equal proportions by weight of a silicone oil and a pigment which may be titanium dioxide, talc, zinc oxide, or titanium hydroxide. A permanent record of the matter inscribed may be obtained by photographing an image in the region L on microfilm. The image is erased in two stages, partly by a smoothing roller 12 fitted with a foam rubber sleeve 13 having a smooth, non-porous outer surface, and finally by a roller 6 bearing a felt annulus (21), Fig. 3 (not shown), covered by a nylon fabric sleeve (22), and incorporating an annular paste reservoir (23) from which paste can be squeezed through the felt annulus by an annular piston (27) under the action of a screw (26) to replenish the layer of paste on the carrier 1. The paste is applied only to the central region of the carrier 1, and is prevented from spreading to the edges by a scraper 11 comprising a block (34), Fig. 4 (not shown), of polytetrafluorethylene, formed with a groove receiving the carrier 1, and fitted with lugs (30, 31) carrying flexible strips (28, 29) disposed at an angle to the direction of motion of the carrier 1 so as to displace the paste layer towards the centre of the carrier. Letter spacing; line spacing; tensioning and winding arrangements.-The carrier 1 may carry a single line of characters, the letter spacing being effected by a drive roller 2 driven stepwise by a motor 35. Alternatively, lines of characters may be printed transversely of the carrier 1 by a ball-shaped type head (not shown) traversing the carrier, the roller 2 effecting line spacing. A pivotally mounted roller 3, urged counterclockwise by a spring 7, tensions the carrier 1. The carrier may be removed by releasing the tension by pivoting the roller 3 clockwise and swinging the erasing roller 6 out of contact with the carrier. Types.-The raised character 10 on the impression member 8 is formed with a curved impression surface (17), Fig. 2 (not shown), for effective displacement of the paste.

Patent GB-422262-A (GB)
Title: Improvements in conditioning mine air
IPC: E21F3/00
Filed: 1934-04-24
Abstract: 422,262. Conditioning mine air. HIRSCHFELDER, P. F., 46, Kerry Road, Parkview, and GRIFFIN, J. D., 43, Anderson Street, both in Johannesburg, South Africa. April 24, 1934, No. 12289. [Class 137] Air in mines is conditioned for ventilation so that it has a cooling effect on the miners' bodies by controlling the moisture content so that the total heat content of the air is of a desirable amount when it enters the working places, the moisture exchange between the air and liquid to which it is exposed being controlled. An aqueous solution of magnesium chloride is preferred. Surplus heat or cold taken from the air by the treatment liquid is stored in the walls of the passage ways over which the liquid is caused to flow, and any natural streams of water in the mine are prevented from making contact with the ventilating air. The heat content of the ventilating air is measured and the vapour tension of the liquid adjusted so as to obtain the desired heat content at the workings. Wetting for dust allaying is effected by the treatment liquid. In the downcast shaft 2 of a mine, perforated pipes 3 spray the walls the liquid being collected by troughs 4. Storage reservoirs 5, 6 for weak and strong solutions are provided, and pipes 7, 8 carry these solutions down the shaft. Humidity detectors 11 open valves 9 or pipe 7 when the air is dry, and valves 10 on pipe 8 when the air is wet, both valves remaining closed when the air does not require conditioning. The liquid from troughs 4 is returned to storage tanks 12, 13, 14 according to its degree of dilution, and is clarified and concentrated by plants 15 and 16. Exclusion of uncontrolled water is effected by a trough 17 below a fault 18, and by a trough 21 to collect water from an underground stream from which it is returned to the surface by a pump 22 and pipe 19. Open pans 25 of the solution may be used, and the passages and broken rock wetted by sprays 26 of the solution, sumps 31, 32, 33 collecting the liquid which is returned to the tanks at the surface. The upper part of the shaft may be jacketed to maintain artificially a warm or cold shaft wall over which the treatment liquid is circulated.

Filed: 1920-03-17
Abstract: 165,386. Fairweather, W., (Singer Manufacturing Co.). March 17, 1920. Button-hole sewing-machines. - 'Work-clamps, closing, spreading, and opening. The upper clamping members 47 are mounted upon pins 45 and are closed by cams 50 on coaxial spindles 46 connected so as to rotate together by levers 56, 57. The spindles 46 are actuated by a lever 181 when the latter is engaged by the lever arm 177 in starting the machine. The clamp-plates are pivoted on the plate 35 at 41, and are moved apart to spread the work after the clamps are closed by means of toggle-levers 195, 197, Fig. 2, operated by a lever 192 and a latch lever 188 connected to a depending lever arm 178. The lever arms 177, 178 are parts of a, three-armed lever, and the other arm 176 carries a spring-pressed pin 174, which is normally held in an inoperative position. When the starting-treadle is depressed, the pin 174 is released and enters a cam-groove in a continuously rotating belt pulley 171. After a single revolution of the pulley, during which the clamps are closed and spread, the pin 174 is ejected from the camgroove by a projection 173 and is re-engaged. The work-clamps are opened only after a cutting operation and by means of a cam 347 on the single-revolution cutter-shaft 170, which engages a lever 344, and by means of a push rod 339 and a lever arm 338 turns the cams 50 into inoperative positions. At the same time, a cam 213 on the cutter-shaft actuates a slide 212, and by means of a tappet-lever 209 bends the toggles 195, 197 to permit the work-clamps to move towards one another. The cutter levers are actuated from the single-revolution cutter shaft 170, which is brought into action by means of a cam-lever 326 when the latter is turned upon its pivot 327 by a cam projection 325 on a disc 324 mounted to rotate with the feed-cam. A slide 329 in the lever 326 forms the operative end of that lever and the cutting operation, and consequently the opening of the work-clamp, can be prevented by drawing the hand-lever 330 forwardly and so withdrawing the slide 329 out of reach of a lever 312. The invention is shown applied to a machine as described in Specification 164,858.
