Abstract: 244,178. Novocrete & Cement Products Co., Ltd., and Burney, C. D. Sept. 12, 1924. Waterproofing; proofing against bacteria and vermin; proofing processes and compositions; wood, treating with liquids. - Loose organic material such as sawdust, wood waste, cork, coir, hemp, sizal, paper, pulp, &c. is impregnated with a solution (not highly basic) of a compound of iron, aluminium, calcium, cobalt, nickel, chromium, copper, zinc, or tin, and an insoluble precipitate is produced by treatment with an alkali, alkaline carbonate, phosphate, oxalate, or aluminate, or carbon dioxide; or by heating, by exposure to air, or in some cases by reaction with the cellulosic material itself. The precipitating agent may be mixed with the fibrous material before the impregnation with the metallic salt solution takes place. Numerous examples of suitable reagents are mentioned, of which the following are typical :-(1) ferrous chloride precipitated by sodium carbonate, (2) zinc chloride precipitated by sodium carbonate, phosphate, hydrate, or aluminate or lime, (3) aluminium acetate precipitated by ammonia gas, an alkali, or the action of heat, (4) sodium aluminate precipitated by carbon dioxide, (5) lime water precipitated by ferrous chloride, sodium aluminate, oxalic acid, or carbon dioxide, (6) chromate of iron precipitated by reaction with the fibrous material itself. When the mineralized material is to be mixed with cement, the free lime in the latter may serve as precipitating agent. The metallic salts may be selected to give coloured precipitates, or to serve as fungicides or insecticides. The mineralized material may be combined with cement &c., with or without a proportion of larger pieces of wood also mineralized by the same process. The mixture may be moulded under pressure and may be reinforced. The product may resemble either wood or stone according to the proportion of organic materials used. Specifications 238,948, 240,561, 244,142, and 245,812, [all in Class 87 (i), Bricks &c.], are referred to. According to the Provisional Specification, any suitable solution of a metallic salt (other than a highly basic solution) may serve as impregnating agent, and any precipitating agent may be. used.

Filed: 1975-05-20
Abstract: 1505166 Multi-stage centrifugal separator DONALDSON CO Inc 20 May 1975 [20 May 1974] 21638/75 Heading B2P A gas from which particulate matter is to be removed is drawn into an elongate container such that it is caused to flow vortically in one axial direction with respect to an outer annular wall of the container and it is then constrained to be drawn through a labyrinth provided by passageways between concentric annular walls whereby the gas continues its vortical flow radially inwardly to a central passageway of the container, the particulate matter being caused to impinge on the successive annular walls by the centrifugal force to which the gas is subjected as a result of its vortical flow, the gas flow in adjacent passageways being in opposite axial directions, the innermost pair of annular walls having a helical partition arranged in the passageway extending between the walls such that the vortex energy of the gas is reinforced, and cleaned gas being withdrawn from the container through the central passageway. As shown in Figs. 2 and 4, a two-stage separator comprises a plurality of coaxial cylinders 10, 11, 12, 13. Gas laden with particulate matter is drawn, by means of a pump or blower connected to the outlet 25 of the cylinder 13, from a riser 70 and through a tangential inlet 14 into the outer cylinder 10 which at the top has a closure defining a helical surface 16 which directs the gas downwardly. After reversal and separation of heavier particulate matter, the gas passes upwards between cylinders 11 and 12 into a plenum chamber 72 where it reverses to pass between cylinders 12 and 13 where its vortical motion is increased by a helical blade 26. After reversal and separation of the lighter particulate matter, cleaned gas is drawn out of the separator through the cylinder 13. The angular relation, about the axis of the separator, between the leading edge 73, Fig. 4, of helical blade 26 and the point of tangency 74 of the inlet 14 with the cylinder 10 is is chosen to ensure that "feed back" vortex upstream of the blade does not oppose the input vortex but augments it. The separated lighter and heavier particulate matter are collected in inner and outer chambers 36 and 37 respectively of a hopper 30-33. A counterweighted, pivotable door 40 having a gasket 54 is used to close and open an aperture provided in the sloping bottom plate 35 of the hopper and serving to discharge particulate matter from chamber 36, the door being kept closed by the negative pressure in chamber 36 when the separator is in operation. A second pivotable door 60 made up of layers 64, 65, 66 of material of different stiffness is used to close and open an aperture provided at the bottom of the wall 32 of the hopper and serving to discharge the particulate matter from the chamber 37, the door during operation of the separator, being kept closed by the negative pressure which prevails in chamber 37 and in a channel 61, Figs. 2 and 8 which surrounds the aperture on three sides and is connected by a T-pipe 62 with chamber 36.

Abstract: 1359757 Data processing systems INTERNATIONAL BUSINESS MACHINES CORP 10 May 1972 [30 June 1971] 21692/72 Heading G4A Messages are transmitted between a plurality of functional units, e.g. processors 12, by way of ring-connected shift registers 26, 27, each functional unit being connected to receive and transmit messages at corresponding locations on two rings 26, 27. There may be a plurality of "bands" of units 12 each connected between a pair of shift register rings, each unit occupying a segment of a band, and further shift register rings may be provided for interconnection of the units 12 along the segment lines. Each unit 12 may have an input buffer and an output buffer for each of the two associated rings 26, 27 and gating circuits controlled by buffer status bits, address and message control bits to route each message over the shortest available path to the required destination. For example, a message intended for unit P11 and being shifted round ring 26 may not be accepted by P11 because its ring 26 input buffer is full. The message may then be transferred to ring 27 via the corresponding output buffer of unit P12 to be returned to P11 in the reverse direction along ring 27.

Title: Improvements in or relating to stabilising means for a body subjected to the influence of angular motion
IPC: G01C21/18
Filed: 1933-08-02
Abstract: 425,034. Self - levelling apparatus. VICKERS - ARMSTRONGS, Ltd., and WATSON, J. P., Vickers House, Broadway, Westminster. Aug. 2, 1933, No. 21752. [Class 113 (i)] [See also Groups XX, XIX, and XXXVIII] Mechanism for moving a body to be stabilized relatively to a support, e.g. a ship, subject to angular motion is under the dual control of two gyroscopes or equivalents, e.g. pendulums, responsive respectively to the degree and to the rate of deviation of the support from its mean position. As shown a reversible electric motor 6 is connected to the power mains 7 through two potentiometers 8 and 9 having sliding contacts 10, 11 under the control of the gyros. The contact 10 is moved when the gyro 1 precesses against the tension of springs 2 in accordance with the rate of deviation of the support. The contact 11 is moved by the unconstrained gyro 3 through gearing 14 in accordance with the amount of deviation of the support. The contacts 15 co-operating with the sliding contact 11 are mounted on a disc 19 driven by the step by step motor 18. The motor 6 is geared at 16 to the body 5 to be stabilized and drives a transmitter 17 actuating the motor 18. In a modification, the contact 11 works between two contacts on the disc 19 serving through relays to determine the direction of rotation of a motor which is combined by a differential gear with a second motor connected to the mains through a potentiometer having a sliding contact controlled by the gyro responsive to rate of deviation. The output of the differential gear drives a transmitter serving to actuate two step by step motors for the stabilizing adjustment of the body 5 and the follow up of the disc 19 respectively. In a further modification a differential gear is connected through gearing to the follow-up and the body to be stabilized and is driven by a motor, the direction of rotation of which is under control of the gyro responsive to the amount of deviation and by a shaft driven from a constant speed motor through variable speed gearing under control of the gyro responsive to rate of deviation. The body 5 may be stabilized about two axes at right angles by duplicating the apparatus. The gyroscope 3 responsive to the amount of deviation may be replaced by a pendulum geared by a toothed quadrant and pinion to the contact arm. Fig. 5 shows a device which may replace the gyro 1 responsive to rate of deviation. The pendulum 60 as it moves on the pivot 61 rotates the shaft 65 and disc 66 through gearing 62, 63, 64. A weighted arm 71 fixed on a spindle 67 rotating in bearings on the edge of the disc 66 swings against the tension of spring 72. The spindle 67 is geared to a sleeve 75 having threaded engagement with a screw on shaft 65, the consequent axial movement of the sleeve being caused to operate the contact arm 12.

Title: Means for loading loose materials into vehicle bodies or other receptacles
IPC: B65F3/18
Filed: 1946-07-23
Abstract: 614,739. Loading vehicles. NASH, A. G. FRAZER-. July 23, 1946, No. 21951. [Class 78 (iv)] In means for loading loose materials into vehicle bodies or other receptacles, a trough or open-topped container is mounted for traversing movements over the body, means being provided for tipping the trough at one or more points along its path of traverse and means being also provided for lifting a dustbin or container and tipping it to discharge its contents into the trough. The trough 60 into which the contents of a dustbin 29 are tipped is pivotally mounted on a carriage 61 having rollers 63 running on rails 64 traversing the body 11 of the vehicle 10. Traversing is effected by means of a cable 65 connected to a double acting hydraulic ram. The means for tipping comprises a rack bar 74 with pins 75. A toothed quadrant 77 is secured to the end of the trough 60 so that its teeth engage between the pins 75 when the rack bar 74 is displaced. An arm 78 pivotally mounted at 79 on the carriage 61 carries a scraper bar 80 connected by a link 81 to the end of the rack bar 74. If the arm 78 is turned the rack bar is displaced and the toothed quadrant 77 causes the trough 60 to be tipped. The trough is tipped automatically when the scraper bar 80 engages an abutment 82 at the end of the body or contacts the rubbish or a trip lever. The direction of traverse of the carriage 61 is changed automatically by a roller 84 mounted on a lever 83 connected to the arm 78. When the trough is tipped the roller engages a displaced rail 85 suspended on links 86, longitudinal movement is transmitted by a rod 87 connected to a control valve mechanism 96 for ram 68. The trough is stopped at the rear end by a projection 100 on the carriage stopping the ram. The dustbin is supported on a carrier 26 and is raised along vertical guides 25 by chains 35 operated by a ram 36 with a piston 37 connected to a carriage 38. The upper ends of the guides are closed and serve as a pivot for tipping. The return movement is effected by a spring and gravity. The control valve mechanisms for the rams are interconnected. The ram 36 is controlled by valve mechanism 90 operated by a lever 91 which has two arms 92 and 93, one connected to the valve 90 and the other to a cable 94, the other end of the cable being slidable in a bracket on a lever 95. The rod 87 is also slidable in another bracket on the lever 95 and is connected to control valve mechanism 96 for controlling the ram operating the trough. The space at the rear end of the hood 14 is closed by a hinged door 49, a projection 27 on the carrier rocks a lever 51 connected to the door to open it as the carrier tips. To discharge the body of the vehicle 10 a hydraulic ram 12 is operated, the body 11 pivots on the chassis. The end panel 13 is raised automatically with the hood 14 which is pivotally mounted at 15 on the body.

Title: Improvements in or relating to pneumatic devices for throwing small projectiles
IPC: F41B11/51
Filed: 1946-07-23
Abstract: 614,740. Pneumatic small-arms. BOULET, R. July 23, 1946, Nos. 21954 and 21955. Convention dates, Nov. 22, 1945 and May 23, 1946. [Class 119] [Also in Groups VI and XV] A pneumatic device which may be incorporated in hunting weapons is characterised by the interposition between the compressed air supply and the projecting barrel or part thereof of at least one flexible disc or diaphragm provided with a hole of smaller diameter than that of the projectile to be thrown. The device in its simplest form comprises a breech member 1 provided with a conical recess 2 communicating with a firing chamber 3 of sufficient size to take one projectile P. Across the firing chamber is stretched a rubber diaphragm 4 provided with a hole 4a of smaller diameter than the projectile P, said diaphragm being held between a disc 5 and a ring 6. All these parts are held in position by the barrel tube 7 or part thereof. If the diaphragm is of sufficient strength a gun incorporating the device may be used for hunting, Fig. 17. The firing chamber 73 is constituted in a member 72 in front of which the resilient diaphragm 74 is located and held in position by the tube or barrel 70. The projectiles 76 are contained in a chamber 75 which communicates by passages 77 normally closed by a valve 78 with a compression chamber 79. This latter communicates by a passage 81 provided with a non-return valve 82 with the cylinder 80 of a pump. A piston 83 slides in the cylinder 80 and is fast on a movable rod 84 extending out of the butt 85 and carrying a butt-plate. The valve 78 carries a button 90 which is moved by the conical end of rod 91, thus lifting valve 78 from its seat. The rod 91 is formed with a push-button 92 and is normally held retracted by a spring 93. To load the gun it is tilted forwardly to roll a projectile 94 into the chamber 73. The butt plate is brought to the shoulder and the butt moved to it sufficient times to deliver compressed air into the chamber 79. After taking aim, the button 92 is pressed releasing the compressed air through the passages 77 into the chamber 73, forcing the projectile 94 suddenly through the hole 95 in the diaphragm 74. The gun may be modified by employing up to three resilient diaphragms together with three non-resilient washers in different combinations to graduate the resistance to the passage of the projectile. In a further modification the projectiles are stored in a magazine rotatable in a plane perpendicular to the axis of the barrel. A pistol incorporating the pneumatic device is also described (see Group XV), said pistol being operated by hand pressure on a bulb in the butt.

IPC: F02C7/277
Filed: 1953-08-10
Abstract: 778,361. Gas turbine plant. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 9, 1954 [Aug. 10, 1953; Sept. 18, 1953], Nos. 22033/53 and 25854/53. Class 110 (3). [Also in Group XII] In apparatus for generating a flow of gaseous working fluid by decomposition of fuel supplied to a reaction chamber in which the pressure developed by decomposition of the fuel is utilized to create a flow of fuel for decomposition into the chamber, auxiliary and main reaction chambers are provided in communication with one another whereby heated gaseous products from the auxiliary chamber may enter the main chamber so as to effect decomposition of fuel introduced thereinto. The pressure produced in the auxiliary chamber is utilized to cause fuel to flow into the main chamber from a source of fuel supply. In Fig. 1 of 25854/53, main and auxiliary reaction chambers 1 and 2 are provided in a common casing, the two chambers being separated by a partition 4 in which is an orifice 5. A monofuel is supplied through the pipe 61 to the auxiliary chamber and decomposition is effected by a heater 7. Gases from the auxiliary chamber pass through pipe 13 to the space above the piston 12 which is disposed in the fuel supply chamber 9. The piston is forced down and fuel passes through pipe 81 to the main reaction chamber 1, where decomposition is initiated by decomposition products issuing from the auxiliary chamber 2 through the orifice 5. The decomposition products discharge at 8 and pass for example to a starter turbine of a prime mover such as a gas turbine engine. A groove 14 is formed in the piston 12 and is connected to atmosphere. A non-return valve 11 is fitted in the fuel supply pipe 10 to the fuel chamber. In a second embodiment, the fuel supply line 8<SP>1</SP> is also connected to the auxiliary chamber 2, the supply of fuel to the main chamber 1 being delayed by a time delay switch until decomposition products are issuing through the orifice 5. In this embodiment the piston 12 is given an initial movement by an external force so as to cause fuel to flow to the auxiliary chamber. In Fig. 2 of 22033/53 a metal bellows 5 is fitted in the fuel supply chamber 6 in place of a piston, fuel being supplied to the space beneath the bellows through pipe 9. Fuel is supplied from the chamber 6 to both the main and auxiliary reaction chambers 1 and 2, the time delay switch being shown at 16. An initial force is applied to the bellows 5 to cause fuel to flow to the auxiliary reaction chamber 2. Specifications 520,113, 542,720, [both in Group XXIX], 695,048 and 726,897 are referred to.
