Abstract: 223,690. Ormond, J. J. Aug. 13, 1923. Cylinder offset machines; set-off, preventing.-Surfaces of relatively soft material, such as rubber or rubber composition as used on offset printing rollers, are cleaned by the flat surface of a hard disc rotating on an axis perpendicular to the line of contact of the surface and the disc. In the machine shown in Figs. 3, 4 and 9, the offset roller 5, carried forward on moving chains 20, rolls over inked printing-plates 2, 2<1>, 2<11> and prints the design on a plate or sheet on a support 4. When the roller 5 has been carried round as far as the bottom of the sprocket 13, its ends 30, 31 contact with belts 32, 33 travelling from left to right so that the roller is spun round at a high speed, about 3,000 revolutions per minute. As the roller advances from right to left, its surface is brought into contact with a horizontal disc 40 of hard material, preferably metal, rotating on a hollow vertical shaft 41 at about 300 revolutions per minute. The disc may be sprayed with a suitable solvent, e.g. kerosene, to facilitate the cleaning of the roller. The shaft 41 is supported in bearings 60, 70, Fig. 10, at the end of arms 61, 67 clamped by a hand-wheel 66 to the frame 63. By unclamping the hand-wheel 66, the disc 40 and its mounting may be tilted to one side or the other and bv shifting the lower bearing block 70 in its slot the disc mav be tilted forward or backward. The disc may be raised or lowered by screwed rods 74, 75 whose roller ends bear against the driven grooved disc 71 fixed on the shaft 41. Bearing on the disc 40 is a scraper 42 having two slots, one of which contains a wick moistened with kerosene &c. and the other holds a scraper blade of bone, ivory, hard rubber, &c. which scrapes the ink and solvent from the face of the disc and directs it to flow away down the hollow shaft 41. After leaving the disc 40, the roller 5 is wiped and polished by a broad belt 45 of absorbent textile fabric supported by a steel band travelling in the same direction as, and between, the bands 32, but at a lower speed. When the roller 5 travels round the sprockets 12, its spinning motion is stopped by contact with the rounded ends of fixed guide rails 25, 26, where it is in position to recommence the printing operation. Specifications 4858/04 and 223,689 are referred to.

Title: Improvements in or relating to a device for loading preforms into the die plate or loading board of a multiple cavity moulding press
IPC: B30B15/30
Filed: 1943-12-13
Abstract: 575,325. Feeding preforms to multiplecavity moulding presses. NEWTON, E. P. (Stokes Machine Co., F. J.). Dec. 13, 1943, No. 20869. [Class 87 (ii)] Preforms contained in a hopper 15 fall into a tray 3 and thence through holes in the tray down tubes 6 and through,holes in a movable plate 8, finally coming to rest on the imperforate parts of a stationary perforated plate 7. When a multi-cavity die plate 2 (or a loading board) moves to the left out of a press disposed to the right of the apparatus shown, it comes to rest with its cavities disposed under the apertures 7a in the plate 7. As it comes to rest, it engages brackets 8e on the plate 8 and moves the latter, with its preforms, to the left, and the preforms drop into the cavities in the dieplate &c. The die-plate &c. then moves to the right, back into the press. The plate 8 is restored to the position shown by a spring, or may be locked in the delivery position by a pin (descent of the preforms being then prevented by the imperforate parts of the plate 8). The tray 3 and plates 7 and 8 form part of a unit which is mounted on rubber blocks 11a, and to facilitate movement of the preforms, this unit may be vibrated by a device 12. The vibrator 12 may be electrically operated, continuously or intermittently : if intermittently, its energizing circuit may be controlled by a movable part of the press, e.g. for a short period during each moulding cycle. The preforms may be preheated by surrounding the tubes 6 with electrical heating elements or hot fluid. To reduce the weight of the vibrated parts, the tubes 6, tube housing 4 and plates 7, 8 may be of " Bakelite " (Registered Trade Mark). The vibrator 12 may be attached to the tray 3, in which case the tubes 6 may be made of flexible material. The hopper is carried by a hood 13 and may be adjusted vertically by means of screws 14.

Title: Process for the separation of acetylene from gaseous mixtures
IPC: C07C7/11
Filed: 1966-05-11
Abstract: 1,125,833. Purifying acetylene. MONTECATINI EDISON S.p.A. 11 May, 1966 [29 May, 1965], No. 20880/66. Heading C5E. In a solvent extraction process for purifying acetylene obtained by cracking hydrocarbons, wherein the acetylene-containing solvent is degassed in countercurrent to an acetylene stream to produce acetylene, solvent and a gaseous acetylene-rich effluent also containing impurities such as CO 2  and ethylene, the effluent is (instead of being recycled as such) solvent-extracted to remove most of the acetylene contained therein, the resulting solvent stream being recycled to the solvent undergoing degassing, preferably at a position where the gas phase in contact with the solvent in the degassing zone has substantially the same acetylene/impurity ratio as the gas dissolved in the recycled solvent stream. The residue from the solvent-extracted gaseous effluent may be either removed from the system or recycled to join the cracked gas fed to the system, depending on the quantity of residual acetylene contained therein. In Examples, the solvent used is N-methyl pyrrolidone. The process provides improved plant capacity since the solvent extraction zone does not have to cope with large quantities of recycled acetylene.
