Title: Radial extrusion die
IPC: B29C48/08
Filed: 1956-08-08
Abstract: <PICT:0810028/IV (a)/1> A die head for the extrusion of organic thermoplastic sheet comprises three coaxial parts; an internally-cylindrical housing 12 forming an extension of the outlet 10 of a plastics extruder or pump, a core 16 fixedly spaced from the housing to provide an annular passage 30 and to distribute plastic material substantially uniformly therein, and a crown 20 secured to and spanning the core 16 so that between the adjacent faces of the crown and housing is formed a radial passage 26 into which the core or crown or both divert the plastic material from the annular passage 30.  The crown is rigid at the centre and is made yieldable near its circumference so that by adjusting pressure and tension means the width of the passage 26 can be altered.  An annular groove 41 and radial grooves (not shown) are machined in a flange 40 on the crown, to make it yieldable under the action of screws 47, 48, threading into radial bars 45 attached to the rigid part of the crown and into the flange 40.  The crown may be heated by heating fluid passing through a passage 52 in a ring carried by the bars 45.  The core 16 is rigidly attached to the housing 12 by the perforated flange 17, and the crown 20 is accurately centred on the core by dowel pins 21 and is secured thereto by the threaded pilot shaft 22 and its lock-nut 23.  Specification 798.194 is referred to.  Reference has been directed by the Comptroller to Specification 755,983.

Filed: 1972-05-24
Abstract: 1389920 Filters and the cleaning thereof A SCHUTZ 24 May 1972 24434/72 Heading B1D Slurry, e.g. slurry juice in sugar manufacture, is filtered by pumping it from container 20 through pipe 24 into casing 12 which is maintained full of slurry so that it is filtered through perforated discs 13, which are covered with filter cloth, into hollow rotatable spindle 15, the filtrate being withdrawn through pipes 28 and 29; but when cleaning of the filter discs is necessary, the valves are adjusted so that gas, such as compressed air, can be forced from pipe 31 into spindle 15, preferably in several short pulses, and flows through the discs in the reverse direction to the filtrate, while the spindle and discs are rotated by motor 18. During this cleaning operation, slurry flows out of casing 12 through valve 6 into container 20 until the liquid-level in the casing reaches the centre of the discs. The released sludge settles in trough 16. When more thorough cleaning is required, the casing is emptied and the discs are sprayed with water or dilute hydrochloric acid.

Title: An improved lithographic printing machine
IPC: B41F7/12
Filed: 1920-08-27
Abstract: 172,095. Ratcliff, W., and Wallace, H. Aug. 27, 1920. Rotary machines.-In a lithographic printing- machine, the printing-plate and inking and damping surfaces are mounted upon an oscillating cylinder and co-operate respectively with an impression or offset roller, and inking and damping rollers. The cylinder A, formed by end discs connected by segments H, I, L, is oscillated by means of a gear-wheel A<2> and a toothed quadrant C having an arm D<2> connected by a link E to a crank-pin E' extending between a pair of gear wheels E<2> driven by a pinion E<5> on a power shaft E<6>. The segments H, I, L carry respectively the printing-plate, and inking and damping surfaces. Ink is transferred from a fountain roller M<1> to the inking-surface by a messenger roller M<2> actuated by a cam N through linkage N<1>, N<2>, N<3>, and the ink is distributed upon the inking- surface by rollers K and then transferred to the plate-inking rollers I<1>. The plate damping-rollers L<1> receive their supply from the damping-surface on the segment L. In the machine shown, the printing-plate makes an impression on a rubber blanket on a cylinder F which transfers the impression to the paper passing between it and an impression cylinder G. The cylinders F, G are geared together and the cylinder F is driven intermittently in one direction by a pawl or catch from a gear loose on one end of the shaft F<2> and engaging a gear on the shaft A<1> of the cylinder A. The other end of the shaft F<2> has a gear which is driven from a gear on the shaft A' but has a few teeth cut away so that when the driving pawl of the cylinder F is disconnected this cylinder may remain at rest.

Abstract: 896,428. Valves. GEWERKSCHAFT EISENHUETTE WESTFALIA. Aug. 1, 1958  [Aug. 5, 1957], No. 24911/58. Class 135. An hydraulically-operated pit prop has its cylinder, not shown, connected with a pump via passages 3, 4 and a loose ball non-return valve 2 normally movable in the depending skirt of a spring-loaded valve closure 5, in which seats an auxiliary closure 7. In a duct 18 leading from passage 4 is a pressure-relieving device comprising a main closure 13 disposed across the duct 18 and having a through bore 17 with which a second closure 14 co-operates, both closures 13, 14 being urged to the closed position by separate adjustable springs; the second closure 14 opens with small pressure rises whilst the main closure 13 permits the momentary release of a larger quantity of liquid, such as during a rock fall, whereupon both closures 13, 14 open simultaneously. The cylinder may be volitionally relieved by turning a hand wheel 9 and lowering a threaded spindle 8 and a spring-urged rod 10 housed therein, the rod 10 opening the auxiliary closure 7 so equalizing the pressure on both sides of the closure 5 ; further rotation of the hand wheel 9 causes the spindle 8 to abut and unseat the closure 5, the auxiliary closure 7 forcing the loose ball 2 on to its seat. The closures 5, 7 connect the passage 4 to a chamber 19 which opens to the same outlet as the relief valves 13, 14.

Abstract: 1309608 Photo-electric measurement of angular displacement SLIMLOCK ANITA ELECTRONICS Ltd 19 April 1971 [27 Jan 1970] 25132/71 Heading G1A [Also in Division G4] Apparatus for monitoring the angular rotation of a shaft e.g. for use in a tachometer comprises a fixed radial grating, a shaft-mounted radial grating, a light source and detector means receiving the moirÚ pattern produced by the obstruction of light by the two gratings. The arrangement is such as to produce moirÚ image lines of much greater width and spacing than that of the grating lines. Fig. 3 illustrates a suitable shaft encoder with fixed 3 and shaft mounted 1 discs, light source 5 and detector 6. Fig.2, (not shown), indicates how small angular movement may be magnified into large moirÚ fringe movements by suitable spacing apart of the gratings and of the source and detector, and suitable choice of grating line pitches. Preferably, the discs are axially spaced about twenty or more times the line pitch. The discs may be plastics films having photographically produced lines which may comprise 1500 in number. The detector 6 may be a photocell or photo-transistor. The detector signal may be used for feedback to regulate shaft rotation rate or for use as a timing signal when the shaft drives or moves with a tape bearing data e.g. in a tape recorder.
