Title: Paper making machines
Inventor: BERLYN MARTIN JOHN
IPC: D21F9/02
Filed: 1956-07-31
Abstract: 841,484. Fourdrinier paper-making machines. DOMINION ENGINEERING WORKS Ltd. July 31, 1956, No. 23582/56. Class 96. A narrow, modified, high-speed Fourdrinier paper-making machine has a short wire-cloth 5, Fig. 1, the upper run C of which hangs as a catenary between the breast roll 6 and couch roll 7 so that water drainage from the pulp is aided by centrifugal force, and suction boxes and table rolls are not used. The breast roll 6 may be at the same height as, or higher or lower than the couch roll 7. A roll 8 may be tilted to act as a guide roll for correcting wonder of the wire 5, a feeler actuated by deviation of the wire-cloth depressing a plunger 85, Fig. 6, of a cylinder 84 to open a valve 78 and admit servo-fluid at 81, 80 to actuate a piston 73 in a cylinder 74, and move, against a spring 75, a lever arm 71 to tilt the roll 8, such movement depressing an arm 72 to shutoff the servo-fluid and avoid hunting. The roll 9, Fig. 1, is adjustably positioned for control of the amount of slack of the caternary C. The web S may be couched vertically upward with the aid of a water shower 13 an air blast 14 and centrifugal force as the wire moves around the roll 7, or couched at an angle, or vertically downwards. The wet press may have small diameter rolls 18, 19 each backed by two larger rolls 20, 21, and driven by a worm-type speed-increasing gear. No pressfelt is used, and the high speed of the small rolls 18, 19 ensures the web S leaves cleanly. The flow-box 11 may be trunnion-mounted and may have an internal paddle for whirling the pulp and delivering it under pressure. To facilitate wire-changing, the rolls 6, 7, 8 and 9, are cantilever mounted from the machine frame 23, each having a hollow outrigger, 28 or 29, secured at one end to the frame by bolts 30 and extending within the roll shell to support it adjacent its mid-point. The roll shafts 33, 34 pass through self-aligning bearings 32. Specification 841,422 is referred to.

Title: Improvements in combustion apparatus
IPC: F23D5/00
Filed: 1924-10-06
Abstract: 245,497. Valjean, B. Oct. 6, 1924. Open-tray burners; vaporizing-apparatus. - A combustible condition is established at a predetermined point between streams of non- combustibly rich and lean mixtures of gaseous or vaporized fuel and air by movement of one into the other in a direction transverse to the direction of flow. In the combustion apparatus shown in Fig. 1 a cylindrical carburetter 1 is slidable in a casing 20 on angle-sectioned guides 9 until its discharge opening 3 registers with an opening 21 in the base of a fire-box 12. Liquid fuel is supplied to the carburetter by means of a valve-controlled pipe 7 and is vaporized by the reflected heat of the flame. Air enters the carburetter through rows of apertures 5<a> spaced at regular intervals in the carburetter wall 5 so that a series of air-jets A surrounded by envelopes L of lean non-explosive mixture, films E of explosive mixture, and envelopes R of rich non- explosible mixture travel in an atmosphere of vapour towards the opening 3. On reaching the opening a stream of air entering horizontally through an annular slot 11 formed between a ring 4 on the top of the carburetter and a rim 21a on the fire-box 12 causes an intimate mixture to take place so that complete combustion ensues. The casing 20 may be divided by a partition 16. into two chambers to which air under pressure is supplied through separately controlled pipes 30, 31 for passage to the apertures 5a and the slot 11 respectively. Alternatively, the air supply may be induced by the furnace draught through apertures in the door of the casing 20. The gap 11 may be regulated by means of adjustable bolts 25 passing through the ring 4 and engaging the guides 9. Fig. 5 shows a modification in which an oval carburetter 1<e> is clamped between oval cast-iron rings 4e, 4<g> and the ring 4e is formed with a slot 4f for engagement with the track 9<e>. In a further modification, the ring 4e is cast around the upper part of the carburetter. In another construction shown in Fig. 6, the fuel is fed to .an annular vaporizing pan 40 arranged around the upper edge of the carburetter and a stream of air is drawn through a central opening 5<a> in the carburetter. The transverse mixing movement is effected by a baffle 11<a>. Air is admitted through an inlet 41 while the burning operation is being started.

Title: Improvements in or relating to electric discharge tubes utilising secondary emission
IPC: H01J43/02
Filed: 1937-08-30
Abstract: 496,705. Electron beam valves and multipliers. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Aug. 30, 1937, No. 23721. Convention date, Sept. 1, 1936. [Class 39 (i)] In a discharge tube, one or more separate primary electron beams impinge partly on an anode 4 and partly on a secondary-emission electrode 5, the arrangement being such that when the anode potential increases the beams widen and the number of electrons diverted to the anode is increased, while the number of primary electrons passing to the secondaryemission electrode and consequently the number of secondary electrons collected by the anode is decreased ; an undesirable decrease in internal resistance is thereby avoided. In one form electrons from cathode 1, Fig. 1, are formed into four beams by rod control electrodes 2 and pass between screening electrodes 3 to anode 4 and secondary electrode 5 which completely surrounds the other electrodes. In another form, the secondary emission layer 6 does not completely cover the area of electrode 5 struck by the beam, so that on widening the beam the reduction in secondary emission is enhanced. The edge of the layer 6 may be shaped or serrated, Figs. 3, 4 (not shown), to adjust the characteristic to desired shape. The Specification as open to inspection under Sect. 91 includes also arrangements in which the anode is not struck by any part of the primary beam. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,246,886. Extracting flesh from shells of crustacea. J J. S. NISBET. 10 Aug., 1970 [9 May, 1969]. No. 23759/69. Heading A2U. The flesh of edible crustacea such as Norwegian lobsters is extracted by centrifugal force, the lobsters from which the heads have been removed being mounted in carriers which are loaded into a drum rotatable about a vertical axis. In one form of carrier, shown in cross-section in Fig. 2b, a row of headless lobsters is gripped between a projection 19 and a downwardly facing rubber pad on a hinged lid 18 so that the open ends of the shells face, but are spaced from, a curved wall 17. Carriers are loaded into a cylindrical container with their walls 17 facing radially outwardly, and the container secured in a drum which is rotated by an electric motor at e.g. 1000 r.p.m. for 10-15 secs. The drum may also be vibrated, in which case a lower speed of rotation suffices. A modified carrier comprises a frame with a number of horizontal rows of pins 37, Fig. 4, on which the tails of the lobsters are impaled, the position of the frame relative to a tray 34 in which it is received being adjustable by screws 35 so that different sizes of crustacea may be accommodated. Eight such trays are mounted in a rotary drum with their pins 37 directed inwardly so that the lobster flesh, loosened by centrifugal force, slides down the vertical walls of the trays as the drum is brought to rest, and any liquid is retained in the trays by lips 38. An arrangement of two drums driven by Vee-belts from a single electric motor is described. The drums are fitted with vibrators energised through slip rings and are individually controlled by clutches and brakes so that they may operate alternately.
