Title: Process for making vinyl esters
IPC: B01J31/04
Filed: 1953-10-14
Abstract: In the production of vinyl esters by the vapour phase reaction of acetylene with an organic acid at 130-350 DEG  C. in the presence of a zinc acetate or cadmium acetate catalyst on an activated carbon carrier, the formation of acetylene polymers on the catalyst, due to the presence of copper in the carbon carrier, is prevented by adding bismuth iodide or bismuth oxyiodide to the catalyst in an amount of 0.001-0.5 per cent by weight of the carrier (see Group III).  The organic acid may be acetic, propionic, or butyric acid.  In an example, vinyl acetate is prepared by passing a mixture of acetylene and acetic acid vapour through cooled catalyst tubes at a temperature of 180-210 DEG  C.ALSO:Bismuth iodide or oxyiodide is added to a zinc acetate or cadmium acetate catalyst supported on an activated carbon carrier in order to prevent the formation of acetylene polymers (due to the presence of copper in the carbon carrier) during the use of the catalyst in the production of vinyl esters by the vapour phase reaction of acetylene with an organic acid at 130 DEG -350 DEG C. The bismuth compound is added in an amount of 0.001-0.5 per cent by weight of the carrier, either during or after the deposition of the zinc or cadmium acetate on the carrier; for example an acetone solution of the bismuth compound may be applied, followed by evaporation of the solvent.

Title: Overvoltage protective device
IPC: H01T1/14
Filed: 1951-12-04
Abstract: 695,431. Protective arrangements. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Dec. 4, 1951 [Dec. 4, 1950], No. 28375/51. Class 38 (iv). [Also in Group XXXVII] An over-voltage protective arrangement for a line 11 comprises surge diverters 1, 2 (each consisting of spark gaps in series with valvetype resistors) and a change-over switch 13 whereby either of the diverters may be connected between line and earth, there being a control circuit 15 responsive to a prolonged discharge through the connected diverter for causing the switch first to connect in the other diverter and then interrupt the earth connection of the first, to terminate the discharge. The switch 13 may be of the air-blast type having moving contacts 30, 31, Fig. 2, co-operating with fixed contacts 24, 25 carried by leadthrough insulators 22, 23 in the ends of an airtight casing 21, the fixed contacts connecting, respectively, to the two diverters. The moving contacts are operated by a piston 29 movable, under the control of exhaust valves 36, 37, by compressed air admitted to the casing 21 through a pipe 19, the exhaust valves being controlled by solenoid-valves 42, 43 in branch pipes 44, 45. Energization of, say, solenoid 43 opens the right-hand end of cylinder 28 to the atmosphere, so that the piston is urged to the right ; contact 31 engages contact 25, and later, contact 30 disengages an arcing contact 26 associated with contact 24, the arc being extinguished by air blast through the hollow contact 30. The control circuit 15, Fig. 1, includes a current transformer in the discharge path, the secondary winding of which so energizes a pair of relay windings that an armature of the relay assumes, alternately, either one or the other of two possible rest positions with successive discharges and operates contacts causing alternate energization of the solenoids 42, 43.

Title: Radio Beam Capture Circuit Aircraft Guidance
IPC: G05D1/02
Filed: 1967-06-20
Abstract: 1,167,567. Automatic steering control. COLLINS RADIO CO. June 20, 1967 [Sept. 6, 1966], No. 28445/67. Heading G3R. An aircraft is automatically controlled to capture a radio-defined course by finally banking to approach the course by moving in a circle having a radius dependent on the speed of the aircraft. In Fig. 7, a radio course tobe followed is selected by a member 35<1> which adjusts a VOR radio receiver 45 and the rotor of a synchro 20 receiving signals from a magnetic compass (not shown). The output of synchro 20, which thus corresponds to the heading error of the aircraft, is rectified at 22 and made a linear function of the error by a shaping circuit 23 incorporating a Zener diode. This signal is applied through a line 24 to a transistor multiplier circuit 15 which also receives, through a line 14, a signal corresponding to the rate of change of radio angular error derived through a chopper 36 and highpass filter 13 from radio receiver 45. When, as the aircraft approaches the radio course, the output from multiplier 15 on line 17 equals the radio angular error signal applied through a condenser 42, a transistor operated relay 43, 28 influences the aileron control channel 29, 30, 31, to produce maximum banking of the aircraft so that it travels in a circular path to which the radio course line is finally a tangent. The radius of the circular path is dependent on speed but the Specification shows that the tangential meeting with the radio course line occurs whatever the speed, the distance from the radio source, or the direction of the initial approach path.

Title: Improvements in devices for measuring the depression of railway sleepers when rolling loads are passing over them
IPC: E01B35/00
Filed: 1949-11-07
Abstract: 683,398. Linear-dimension gauges. SOC. D'ETUDES MECANIQUES ET D'ORGANISATION INDUSTRIELLE S.E.M.O.I. Nov. 7, 1949 (Dec. 24, 1948; July 7, 1949], Nos. 28469/49 and 28470/49. Class 106 (ii). (Also in Group XXX] A device for measuring the depression of a railway sleeper when a rolling load is passing over it comprises a member 1 which is secured to the sleeper 3 by spikes 2 so that it moves upwardly and downwardly with the sleeper and is slidable relative to a stationary rod 6 which is mounted within a cylindrical guide sleeve 5 at the end of a lateral arm 4 on the member 1, the downward movement of the member 1 being imparted to a cylindrical slider 9, Fig. 3, which is movable upon the rod 6 and is initially located in contact with an abutment 12 on the guide sleeve 5. The slider 9 is provided with longitudinal slits 10 to provide a frictional engagement which holds it in the position to which it is moved. A portion of the lower part of the sleeve 5 is cut away adjacent to a vertical scale 13 which is secured thereon to indicate the distance between the initial and final positions of a collar 11 on the upper end of slider 9. As shown, the lower end of the rod 6 has a head 7 which rests firmly on the ballast 8. The sleeve 5 can be locked temporarily on the rod 6 by a screw 14. In a modification, Fig. 6, two adjustable sliders 17, 19 are employed, the former held on the rod 6 by a set-screw 18 extending through a longitudinal slot in a collar 5 at the end of an arm 4, as in the previous example, and the latter a friction fit on the outside of the collar 5 and set initially with its bottom flange 20 bearing against tongues 21 which extend laterally from the slider 17 clamped on the rod 6. A scale is provided on the sleeve 5. In a further modification a spiked rod which is driven into the ballast at the side of a rail carries a sleeve which is a tight frictional fit thereon and has a tongue extending at rightangles to the supporting-rod, the sleeve being adjusted initially to engage the tongue against the underside of the rail. An adjustable marker slide on the rod is set with its lower edge in abutment with the top of the sliding sleeve on the rod, so that when the sleeve is pushed down, together with its associated tongue, by the passage of a load over the rail, it remains in that position, and the distance between its upper end and the bottom of the marker slide is a measure of the depression of the track.

Title: Improvements in or relating to pressure welding apparatus
IPC: B23K20/02
Filed: 1948-11-03
Abstract: 654,214. Jointing ; welding. GENERAL ELECTRIC CO., Ltd., and SOWTER, A. B. Nov. 3, 1948, Nos. 28586/48 and 2180/49. [Class 83 (iv)] A metal container capable of being pressure-welded is filled with gas at a required pressure, or evacuated and the sealed, in an enclosed chamber formed by a piston 10 and cylinder 1 which co-operate to produce the pressure weld. Preferably, cold pressure welding is employed but some heat may be applied in certain cases and the pressure in the container may be obtained from external means or simply by the compression in the cylinder. For filling and sealing an air pressure cell for compensating the expansion of oil in oil-filled electric cables, two dished discs 2 of aluminium are scratch-brushed on their mating surfaces and placed on an annular shoulder 3 at the bottom of the cylinder 1. The piston 10 having a corresponding annular shoulder 12 is placed in the cylinder and is forced down by press platens 14 to weld the edges of the discs together. A pipe 8, joined to the cylinder by passages 5 and 13, is connected to a supply of air under pressure or, through a two-way cock, to a vacuum pump or a supply of the required gas. The reduction of thickness at the weld is about 70 per cent and is controlled by stops or by making the lengths of the cylinder bore and of the piston such that the required reduction is obtained when the piston and cylinder tops are flush with each other. The shoulders 3 and 12 may be formed by removable tools and their faces may be flat or slightly radiussed. In a modified apparatus, Fig. 2, for evacuating and sealing ionization chambers for an electrical condenser type manometer, the piston 10 and cylinder 18 are inverted and a rubber ring 17 is fitted round the piston. Two aluminium discs forming an outer electrode round an inner insulated electrode are placed on the piston 10, with the terminal of the inner electrode resting in a recess 21 and the piston and cylinder are telescoped to compress the ring 17 slightly to seal the cylinder, full closing being prevented by removable stops. The air in the cylinder is then pumped out through the passage 5, the stops are removed and the cylinder is moved fully down to effect the weld. Similar apparatus may be used in evacuating and sealing radio valves, two radial flanges on tubular copper parts of the valve being cold-pressure welded together. A resistance heating element and an eddy current heating coil may also be included in the apparatus to permit baking and outgassing. The apparatus may also be adapted for welding an angle-section annulus carrying the screen of a cathode-ray tube to a flange on a funnelshaped body part.

An aircraft landing gear comprises two sets of landing wheels, one 18 of which is journalled to the lower or movable part 12 of a freely telescoping leg, and the other 21 of which is journalled at 20 to a lever 19 which has pivotal attachment (as shown, at 17) with the lower part of the leg, and shock absorber means 22 extending between an intermediate portion 24 of the lever 19 and the upper or fixed part 11 of the leg so as to be capable of wholly sustaining the load on the component; the arrangement being such that when the leg and the shock absorber are fully extended, e.g. when the aircraft is airborne, the wheels carried by the lever are lower than the wheels carried by the leg. The lower portion 12 of the leg is limited in its downward movement by a flange 26 on the part 11 which engages a ledge 25 on the part 12, and is prevented from rotating relatively to the part 11 by torque links 13. The leg is pivoted to the aircraft about a retraction axis 14.

Abstract: 970,614. Tipping dustbins. E. ZOLLER, and H. SCHULZ-ZOLLER. July 27, 1962 [July 29, 1961], No. 28901/62. Heading B8E. Apparatus for emptying refuse bins of different sizes comprises a bin pivoting arm 7 actuated by a tilting device 8 and a front plate 3, shutter 1 and closure flap 5 pivoted together at 2. The plate 3 has an aperture for the larger bins which is partly covered by the shutter 1 to provide an aperture suitable for smaller bins 12. A double-acting locking device 4 secures the shutter 1 either to the flap 5 or the plate 3. In use with a large bin hooks 6 are engaged by the bin and a lid projection is taken up by a crossbar 11, Fig. 1, of the lock 4 so that upon operation of the arm 7 the lid, shutter 1 and cover 5 swing together about 2 as the refuse is empted. With a small bin 12, hooks 16 and a claw 22 are engaged and the locking device 4 is manually engaged by a bar 13, Fig. 1, with the plate 3 so that upon swinging of the arm 7 the shutter 1 remains locked to the plate 3 while engagement of a lid projection 17 with a device 18 opens the lid as the cover 5 swings about 2. In a modification, Fig. 4, the lock 4 is biased by a spring 26 to engage the flap 5 in which position it remains during the emptying of a large bin which comes to rest against the plate 3 with the arm 7 at an angle α thereto. When a small bin is in use the arm 7 comes nearer the plate 3 before the latter is engaged by the bin so that a buffer 21 engages a plate 28 and through a lever 27 moves the lock 4 against the spring 26 to engage the plate 3.

Title: Improvements in or relating to washing, dyeing, emulsifying and other apparatus employing constant flux and reflux of a liquid
IPC: D06F17/00
Filed: 1937-10-25
Abstract: 503,348. Dish - washing machines. COREY, A. W., and SONES, W. H. oct. 25, 1937, Nos. 29114/37, 585/38 and 11781/38, [Class 138 (i)] [Also in Groups VIII, III, and IV] A washing-machine comprises an inverted-cupshaped member 2 immersed in the liquid in the washing vessel 1 and provided with a float-operated valve 5, apertures 9 and an inlet 8 for air under pressure which may be derived from a domestic vacuum cleaner. The compressed air depresses the liquid in the cup until the float sinks and opens the valve, the liquid thus surging alternately backwards and forwards. In another form the float is housed in a separate compartment communicating with the cup-shaped member through apertures proportioned to delay the fall of the float, and the air escaping on the opening of the valve is directed by radially and downwardly extending tubes to below the liquid level. In another form the admission of the compressed air causes the cupshaped members to rise. External vanes on the cup and a screw-thread on a spigot secured thereto and engaged by a stationary stop cause the cup to rotate and thereby to increase the circulation of the liquid. In the form shown in Fig. 4, the cup rises under the air pressure but is prevented from rotating by a pin 24 engaging a vertical groove 26 in the recess 27. A plate 23 carried by guides 31 and supporting the goods to be washed is caused to rotate by the rising and falling movement of the cup acting through the pin and cam groove 29, 30. In the form shown in Fig. 5, which is particularly intended for washing crockery, the cup-shaped member 2 is spaced from the bottom of the washing-vessel and is enclosed by a shroud 35 having perforations 37 and apertures 36. The float chamber 12 communicates with the cup 2 and a large aperture 4 therein is normally closed by a valve 5. The crockery is contained in a basket 38. On admission of air under pressure to the cup 2 the water is driven out and a portion of the air passes upwardly through the perforations 37 into the basket. On the delayed fall of the float, the valve 5 opens, air rushes up into the basket, and the water surges back into the oup. The inrush of air causes a fountain of water which is directed back into the basket by a baffle 40.
