Title: Improvements in or relating to the ionisation manometers
IPC: H01J49/34
Filed: 1962-04-13
Abstract: 964,120. Ionization manometers. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 13, 1962 [April 17, 1961], No. 14390/62. Heading HID. In an ionization manometer, the gas is ionized between two apertured diaphragms 4, 5 by a magnetically-concentrated electron beam passing through the diaphragm apertures. The ions are collected by an electrode 11 arranged laterally of the electron beam between the diaphragms 4, 5 and out of direct line of sight of the electron-collecting area of an anode 10 located beyond diaphragm 5. The voltage applied between diaphragm 5 and anode 10 is sufficient to drive ions liberated from the anode towards the cathode 1 under the influence of the magnetic beam-concentrating field 15 so that these ions do not strike the collector electrode 11. As shown, diaphragms 4, 5 form part of a metal box 8 within the open end of which is arranged the ion collector 11 connected to amplifier and measuring instruments 18 and screened by members 13, 14. Dimensions, operating potentials and magnetic field strengths are given, and pressures of 10<SP>-2</SP> to 10<SP>-14</SP> Torr can be measured.

Title: Improvements in or relating to air-supported vehicles
Inventor: MORGAN EDGAR ALLEN
IPC: B65G51/03
Filed: 1966-04-04
Abstract: 1,137,517. Air cushion supporting apparatus. WALT DISNEY PRODUCTIONS. 4 April, 1966, No. 14926/66. Heading B8A. [Also in Division A6] An apparatus for supporting vehicles 3 on cushions of air above a deck 2, comprises valve members 52 set in the deck 2 and automatically opened when a vehicle is thereabove to permit pressurized air to pass from a plenum chamber 14 under the deck 2 into a plenum chamber on the underside of the vehicle. Each valve member 52 is mounted at the upper end of a piston-rod, the lower end of which is connected to a piston slidable in a cylinder 57. With pressurization by a blower 31, of air in the chamber 14, the valve members 52 are raised into their closed position, against spring pressure provided a vehicle 3 is not present above the valve. When a vehicle is present the back pressure of air being received in the vehicle plenum chamber prevents the member 52 closing and as the vehicle moves over the deck 2, the back pressure causes valves thereunder to open. Vents in the valve cylinders 57 control the speed of movement of the piston therein and therefore the valve members 52. The air pressure in the chamber 14 is regulated by a pressure sensing device which controls operation of a gate 129 in an air feed pipe 33 from the blower 31. The plenum chamber 14 is divided into a plurality of pockets each having a gate controlling air flow into the pocket from a supply duct coupled to the feed pipe 33. The vehicle plenum chamber comprises a flexible skirt 77 having a reinforced edge 78 and air may be released from the chamber through nozzles, under the manual control of levers 81 to control rotational direction of the vehicle. The area under the deck 2 is divided into three plenum chambers, two of which are disposed under areas of deck comprising loading bays, and one of which is disposed under a semicircular vehicle riding area of the deck from which vehicles may be swept into one of the loading bays by a motor-driven pivotally mounted boom. The plenum chamber 14 extends under the riding area of the deck 2 and a fenced curb surrounds the whole of the deck. In the embodiment of Figs. 17, 18 (not shown) the valves in the deck (2) are formed as synthetic rubber flaps which without air pressure in the plenum chamber, are biased open by their weight and natural resilience.

Abstract: 433,853. Television. BAIRD, J. L., and BAIRD TELEVISION, Ltd., 58, Victoria Street, Westminster. Nov. 21, 1933, No. 15202/35. Divided application. [Class 40 (iii)] Relates to a television or like system in which a cathode ray or electron tube device having a luminescent screen is used and in which a continuously moving cinematographic or like film is scanned by the light spot produced on the luminescent screen by the electron beam of said device in strips extending transversely of the film, the path of traverse of the light spot being rhythmically changed in a direction normal to its length and consists in a method of producing traversal in which the effective position of the strips successively scanned on the film is changed progressively in a direction in opposition to that of motion of the film by such amounts that when the film has moved a fraction of a frame-height from the epoch of inception of the scan, the said position has changed by the remainder of a frame-height. Thus, the effective position of a scanning strip may be traversed in a direction normal to its length and in opposition to the direction of motion of the film by a distance corresponding to half a film frameheight while the film moves half a frameheight. If desired, the scanning may be effected in intercalated lines.

Title: Method of conducting catalytic conversions
IPC: B01J19/18
Filed: 1946-05-21
Abstract: <PICT:0615479/III/1> A method of conducting a catalytic conversion in a heterogeneous mixture of phases comprises passing the immiscible phases, one of which contains the catalyst, simultaneously and in suitable proportions under reaction conditions of temperature and pressure through a reaction zone bounded by two spaced relatively smooth surfaces, the reaction zone being of cross-section and length to accommodate the desired throughput at the desired space velocity with non-turbulent flow, and maintaining a condition of eddy flow in the zone by maintaining the boundary surfaces in a relative motion which is parallel for any point of one surface and at least one corresponding point of the other surface. Preferably, the two surfaces are surfaces of revolution (e.g. of concentric cylinders) which are maintained in relative angular motion about an axis of rotation, but they may be plane surfaces. As shown in Fig. 9, the reactant, e.g. an olefin or mixture of hydrocarbons is introduced through a line 27 and is forced up through an inner rotating cylinder 21 by vanes 23 passes through ports 24 into an annular reaction zone bounded by an outer shell 20 and the cylinder 21 passing downward in a spiral direction in the form of a fine dispersion under the action of the rotation. The catalyst particles, which are liquid and heavier than the reaction feed, settle to the bottom of the enlarged quiescent bottom section of the shell 20 for recirculation by scoops 26, reacted catalyst-free material leaving through a line 28. According to a modification (Fig. 10, not shown), two reaction phases of different density are passed through the reaction space in counter-current, the heavier phase entering at the top and leaving at the bottom.  The lighter phase may be a gas.ALSO:<PICT:0615479/IV(b)/1> In the catalytic hydrogenation of nitrobenzene, the nitrobenzene is fed through a line 33 to an annular reaction zone bounded by an outer cylindrical shell 30 and an inner rotating cylinder 39, slurried nickel catalyst being fed through a line 34 and hydrogen through a line 32.  The liquid product containing catalyst in suspension is withdrawn via line 31.

Title: Electric telemetric system
IPC: G08C19/20
Filed: 1946-05-21
Abstract: 616,552. Telemetric systems. AUTOFLIGHT CORPORATION. May 21, 1946, No. 15401. Convention date, June 4, 1945. [Class 40 (i)] A telemetric system suitable for use in aircraft and controlled for example by a pressure gauge, comprises a transmitter producing positive or negative pulses depending on its direction of rotation, and a receiver rotating step-by-step in a direction corresponding to the sign of the received pulses. The drive shaft 10 of the transmitter, Fig. 1, rotates a magnet 11, having alternate poles of opposite polarity, close by the poles of a like-ended magnet 9 fixed to a shaft 7, whereby the magnet 9 follows the magnet 11 when unlike poles come adjacent, until rotation of the shaft 7 is stopped by a generating magnet 8 fixed on the shaft 7 coming against non-magnetic inserts 2a on cores 2 of coils 3, 5 (assuming the shaft 10 is driven anti-clockwise from the position shown in Fig. 1). Continued rotation of the shaft 10 brings like poles of the magnets 11, 9 adjacent whereby the magnet 9 is repelled at high velocity in the opposite direction and the magnet 8 comes back against the cores 2 of coils 4, 6 and the operation then repeats. The high velocity movement of the magnet 8 generates voltages of a certain sign in the coils 3-6 which are so connected together that their voltages are additive. To ensure that the receiver is not affected by the pulse generated when the magnet 9 is following the magnet 11, the driving velocity of the shaft 10 must be slow relative to the velocity at which the magnet 9 is, repelled. The shaft 10 when controlled by a pressure gauge may be driven through elliptical gearing to make the transmitter more sensitive over part of the range. In the arrangement shown, two pulses are produced per revolution of the shaft 10, but more pulses may be produced by increasing the number of poles of the magnet 11. The pulses from the transmitter energize the electromagnet 15, 16 of the receiver, Fig. 5, causing an X-shaped polarised armature 17, normally held central by springs 30, 31, to swing in a direction depending on the sign of the pulses, and to correspondingly rotate a shaft 18. An arm 19 fixed to the shaft 18 carries pawls 20, 21 which co-operate with stops 22, 23 on a fixed frame and engage respectively ratchets 25, 26 mounted on a shaft 29 having a pointer 28. Movement of the armature in either direction causes one pawl to disengage its ratchet, Fig. 4, and the other to rotate the shaft 29 by one step. In another construction the armature 17 may have only a pair of poles and the core 16 a single pole. In alternative constructions of the transmitter, the magnets may be energized electrically or the cores 2 or the mounting base 1 may be magnetized; further, the magnet 9 may drive the magnet 11 or the magnets 8, 9 may be in alignment and constitute a single magnet. Moreover, the coils need not have cores and only one or two coils may be used. Also, the magnet 9 may have only one arm in which case the shafts 10, 7 need not be coaxial.
