Title: Improvements in and relating to fluid flow sensors
IPC: G01F1/32
Filed: 1962-12-04
Abstract: 1,039,870. Pure fluid amplifiers. HONEYWELL Inc. Dec. 4, 1962 [Dec. 4, 1961; Dec. 5, 1961], No. 45842/62. Heading G3H. A fluid flow sensing device comprises a conduit with a blade mounted therein in such a manner that a rotational component of fluid flow about the conduit axis produces a difference in pressure between the sides of the blade,there being means associated with the blade for providing a signal dependent upon said pressure difference. The vortex unit, Fig. 2, comprises two circular discs 11, 13, concentric axial outlets 42, 52, and an annular inlet 15 comprising a porous ring held between the two plates and formed of a constrained mass of glass microspheres, a porous ceramic material, or a sintered metal. Any small degree of rotation of the vortex unit will give the incoming fluid a tangential component of velocity which will be very considerably magnified due to the vortex effect on reaching the outlet pipes. The vortex unit may be constructed with a single outlet, and the outlet/(s) may be offset from the vortex chamber axis. The plane surfaces of the vortex chamber may be made bell-shaped to give a smooth blending of the chamber and outlets. The fluid flow sensor, 61 Fig. 2, and Fig. 3, comprises a blade 62 and two pressure sensing parts 63, 64. A pressure difference will occur across the blade when there is a tangential component of velocity present in the flow, and this will be registered by means of the ports 63, 64. If required, the blade may be set at an angle to the axis of the conduit 51, so as to provide a clear null signal. The pressure sensing ports may be dispensed with and signals proportional to the tangential component obtained directly from deflection of the blade.

Title: Apparatus for gripping a column of bricks
IPC: B66C1/44
Filed: 1972-10-05
Abstract: 1374885 Grippers for lifting articles FORREST PASCHAL MACHINERY CO 5 Oct 1972 45934/72 Heading B8H  A course of bricks comprising a plurality of side-by-side columns of bricks (only one shown) is gripped and lifted by means of a gripper head 20 which includes a series of pairs of opposed gripper members 21, each pair being adapted to grip one column of bricks, and each gripper member 21 comprising a gripper arm 34 connected by means of a support bar 31 and arm 33 to the piston 24 of an air cylinder 23 which produces inward and outward movement of the associated gripper arm 34, there being a shaft 27 mounted on each arm 34 which supports a tongue 25 slidably mounted thereon. Each column of bricks is arranged as shown with spacings between some of the bricks, prior to the engagement of the gripper head 20 with the brick columns, and when the gripper head 20 is positioned over the columns of bricks the air cylinders 23 open the gripper members 21 and a stop 28 on each shaft 27 urges the associated tongue 25 to a prescribed position for insertion into the space between selected bricks of the columns, the head 20 is then lowered thus positioning the tongues 25 and a fixed centre blade 29 into the spacings in the brick columns. The cylinders 23 then move the gripper arms 34 inwardly into engagement with the opposite ends of the columns of bricks the bricks in each column being urged inwardly against the tongues 25 and fixed blade 29, each tongue 25 and its shaft 27 moving along with the associated gripper arm 34 until the tongue comes up against the bricks in its path whereafter the shaft 27 moves through the tongue 25 until the latter is engaged by the bricks closing thereupon. The arms 33 in the gripping state of the head 20 compress springs 68 mounted on a support carriage 64 which urge the gripper member 21 outwardly a sufficient distance to release the column of bricks on releasing the air pressure in the cylinders 23. The support carriage 64 is movable along carriage rails 62 mounted on a support beam 60 connected to a hoist (not shown).  In a modification, Figs. 6, 7 (not shown), the fixed centre blade 29 is omitted and in a further modification, Figs. 8, 9 (not shown), a centre blade (29<SP>1</SP>) and only one slidable tongue (25<SP>1</SP>) are used, the latter being mounted on a shaft (27<SP>1</SP>) between two spaced stops (28<SP>1</SP>, 70) such that the stop (70) may be used to urge the tongue (25<SP>1</SP>) against one end of a column of bricks so that the tongue acts effectively as a gripper arm.

Inventor: SIMPSON HAROLD WILLIAM
IPC: B66C23/90
Filed: 1961-12-22
Abstract: 951,558. Extensometers. BABCOCK & WILCOX Ltd. Dec.18, 1962 [Dec.22, 1961], No. 45989/61. Heading G1M. An extensometer comprises levers 2, 4 mounted in a casing 6 on a structural member 12 and an actuator 34 mounted by a block 36 at a different point on the structural member. Differential movement between the mounting points due to strain in the structural member causes actuator 34, 30 to rock lever 2. This motion is transmitted to lever 4 by means of an adjustably mounted cam 40, so that the magnification produced by the levers can be varied. Cam follower 48 transmits movement from cam 40 to lever 4. Lever 4 operates successively microswitches 62, 64, 66 which in turn operate control and warning means. The lost motion between the first switch and lever 4 can be adjusted by a bolt 88 and the individual switches can be adjusted in position by means of slots 94 and clamping screws 96.

Title: An improved process for the elimination of peroxide from ethers
IPC: C07D307/08
Filed: 1962-12-06
Abstract: Peroxides are eliminated from ethers by adding phenothiazine, or a derivative thereof, to the ether, heating the mixture to boiling point and subsequently distilling off the ether. It is preferred to use 1.1 to 1.6 moles phenothiazine per equivalent of active oxygen in the ether.  In the course of the purification treatment the phenothiazine is oxidized to the corresponding sulphoxide which may be converted back to the phenothiazine by treatment with Zn or Fe in acetic acid.  Suitable derivatives of phenothiazine are the alkyl substituted compounds.  Examples relate to the purification of dioxan and tetrahydrofuran.

Title: Improvements in or relating to rotary fluid flow meters
IPC: G01F1/10
Filed: 1963-11-22
Abstract: 981,171. Rotary liquid-flow meters. Soc. Anon. POUR TOUS APPAREILLAGES MECANIQUES. Nov. 22,1963 [Nov. 23, 1962], No. 46235/63. Heading F1F. . A rotary liquid-flow meter of the turbine type comprises a rotor having a shaft 3 (Fig. 2) mounted on stationary journals and carrying two sets of helical turbine blades 2 of identical form but opposite direction of twist and a liquid-deflecting disc 4 at its centre. Liquid entering a stationary casing 1 through a conduit 6 divides and passes through perforated baffle plates 7, 8, flow-straightening vanes 9, annular nozzles 11 and passages 10 before flowing between the blades 2. The spent liquid is deflected outwardly by the disc 4 into a passage 12 leading to a discharge conduit 13, the action of the liquid on the disc 4 serving to centre the shaft 3 and prevent end thrust on the journals, thereby minimising frictional resistance. A proportion of the liquid entering the meters through a conduit 15 (Fig. I) passes through a pair of pipes 17 containing regulating valves 18, the remainder passing into conduit 6 through a pressure-reducing non-return valve 16. The liquid passing through pipes 17 enters passages 10 through annular grooves 19, radial passages 20 in plates 8, annular grooves 26 and passages 27 arranged tangentially to passages 10, whereby the flow of liquid in passages 10 is rendered both tangential and axial to minimise errors at low flow rates. The pressure of the liquid in passages 27 is greater than that of the fluid leaving nozzles 11 owing to the loss of pressure at valve 16 and in the nozzles. In an alternative embodiment (Fig. 4) most of the liquid entering the meter passes through a pressure-reducing non-return valve 24 whilst the remainder passes through pipes 21 and fluid bearings for the shaft 3 before entering the nozzles 11; this embodiment is otherwise similar to that shown in Figs. 1, 2. Valve 24 may replace valve 16 in the first embodiment, and in both embodiments the rotor may be coupled to volume indicating or recording mechanism (not shown).

Title: Character recognition system
IPC: G06V30/184
Filed: 1968-10-01
Abstract: 1,242,696. Character recognition. INTERNATIONAL BUSINESS MACHINES CORP. 1 Oct., 1968 [3 Oct., 1967], No. 46426/68. Heading G4R. In a character recognition system, conflict in the recognition produces conflict signals to cause rescanning of the character in accordance with a predetermined pattern controlled by the conflict signals, the conflict being resolved in response to the detection of crossovers in the rescanning. The character outline is followed round twice, the first time to obtain the maximum and minimum horizontal and vertical deflection voltages of the scanner, for normalization purposes, and the second time to identify the character. If there is a conflict in the recognition logic, it indicates the nature of the conflict (i.e. the possible identities for the character) and causes the character to be scanned in a horizontal and a vertical line, the position of each of these being selected from three possibilities in accordance with the nature of the conflict. The number of crossovers in each of these lines is counted separately and used in conjunction with the nature of the conflict to resolve the conflict. The boundary voltages obtained in the normalization are applied to voltage dividers, taps on which supply voltages for comparison with the horizontal and vertical deflection voltages to control the scanning beam position during the conflict-resolution scan.

Title: Improvements in or relating to the preparation of amidoalkyl starch ethers
IPC: C08B31/12
Filed: 1962-12-11
Abstract: Amidoalkyl starch ethers are prepared by suspending or slurrying a cyanoalkyl starch ether in an alkaline medium, adding an aqueous solution of hydrogen peroxide to the suspension, and allowing the mixture to react while maintaining an alkalene pH. The resulting amidoalkyl ether may be recovered by filtration or centrifugation. The products may be granular or cold-water soluble depending on whether they are derived from granular or pre-gelatinized starch. The reaction with hydrogen peroxide is preferably carried out at 20-40 DEG C., using 0.11 to 2.2 moles of peroxide per mole of nitrile group in the starch.  The reaction medium may be aqueous or non-aqueous.  Reaction time is usually 1 to 16 hours and may be terminated by adjustment of the pH to 6.5 by addition of sodium bisulphite. Depending on the conditions, conversion of nitrile groups to amide groups may be complete or partial, and hydrolysis of nitrile groups to carboxyl groups may be controlled, so that starch ethers containing amide nitrile and carboxyl groups in combination may be formed.  Thin-boiling products may be obtained. The cyanoalkyl ethers, prepared by known methods, may be isolated before reaction with hydrogen peroxide, but in one embodiment of the invention, granular starch is suspended in an aqueous alkaline solution of a cyanoalkylating agent in presence of a gelatinization inhibitor, and after formation of cyanoalkyl starch ether by heating the mixture, an amidoalkyl starch ether is formed in situ by reaction with hydrogen peroxide.  In a further embodiment, a cold-water soluble cyanoalkyl starch ether is reacted in a semi-dry state i.e. as a slurry with hydrogen peroxide.  Any alkali or base may be used for maintenance of an alkaline pH, and may be added periodically during the reaction, or, when cyanoalkylation and hydrolysis is carried out in the same reaction mixture, at the commencement of the cyanoalkylation. The amidoalkyl starch ethers may be derived from naturally occurring starches, partially hydrolysed, dextrinized or oxidized starches, or amylose or amylopectin. Examples describe the preparation of amidoethyl starch ethers.

Title: Oxidation process
Inventor: COMYNS ALAN EDWARD
IPC: C01B13/28
Filed: 1964-11-27
Abstract: Metal oxides are produced by forming a gas mixture containing a first metal halide, a first oxygenating gas and a fuel gas, the quantity of the latter being at least sufficient to maintain the temp. necessary for the oxidation of the metal halide, e.g. at least 600 DEG  C. This mixture is burnt to produce a hot gas containing solid particles of metal oxide.  This gas stream is passed into a reaction zone into which is introduced a second metal halide and a second oxygenating gas, at least one of these being introduced through a plurality of inlets, e.g. up to 20, spaced along the reaction zone in the direction of gas flow.  The necessary temp. for oxidation of the second metal halide is maintained and the metal oxide produced is recovered.  The first and second halide may form a white oxide and may be the same, e.g. chlorides of Ti, Al, Zr, Si.  The first and second oxygenating gases may be the same, e.g. O2, or a free O2-containing gas, e.g. air or O2 enriched air. At least part of the second halide or oxygenating gas may be an unreacted excess of the first halide or oxygenating gas.  The fuel gas may be CO or a hydrocarbon, e.g. C2H6, C3H8 or C4H10.  The initial gas mixture may be preheated, e.g. to at least 150 DEG  C., if the first metal halide is TiCl4 before being burnt.  If the second metal halide is TiCl4 then the particulate metal oxide in the gas stream may have a mean size from 0.01 to 0.25 m .  The ratio of first metal halide to fuel gas may be 1 : 2 to 4. The gas mixture may be burnt through a plurality of channels in a shaft furnace. The amount of metal oxide produced in the reaction zone may be from 1.01 to 10 times the total weight of metal oxide present in the gas stream. TiO2 produced preferably has a mean size of 0.15 to 0.35 m  and may be formed with the addition of halides of Al, Si, Ce, Zr, and/or boron and/or water vapour and/or a subhalide of Ti and/or a source of K ions.  The oxides formed from these additions may form a coating on the particles, especially if introduced after the second halide.  Halogen liberated in the process may be recycled to produce further metal halide for use in the process.
