Abstract: 1,221,109. Velocity-modulated tubes. TOKYO SHIBAURA ELECTRIC CO. Ltd. 26 April, 1968 [27 April, 1967], No. 19842/68. Heading HID. In a velocity-modulated electron tube in which an electron beam, focused by an axial magnetic field, is projected along an axis from a gun to a collector structure past a microwave circuit, the collector is situated in the magnetic field and includes a plurality of apertured electrode plates arranged at an angle to the beam axis and providing an oblique decelerating field, whereby the electrons are deflected sideways, to be collected at reduced velocity and in such a manner that any secondary electrons produced at the collector are diverted away from the microwave circuit. The travelling- wave tube collector of Fig. 4 includes plates 41 to 46 mounted at an angle on insulating rods 47 to 50, held at successively lower potentials, and having apertures 61 to 65 which extend progressively nearer one edge of the plates in accordance with the progressive deflection of the electron beam. The nature of the electron trajectories is discussed. The magnetic field may be provided by a solenoid (Fig. 1, not shown) or by a periodic permanent magnet arrangement. A modification is referred to in which there is a non-uniform spacing between the plates 41 to 46.

IPC: C08F14/18
Filed: 1953-07-20
Abstract: Substituted ethylenes, in which one hydrogen atom of ethylene is substituted by fluorine and the other hydrogen atoms are either unsubstitituted or substituted by fluorine, chlorine or bromine, are polymerized alone or in admixture with other copolymerizable ethylene derivatives in the absence of water but in the presence of ozone and/or a reaction product of ozone and an ethylene derivative containing fluorine, which ethylene derivative is preferably the substance being polymerized.

Title: Improvements in or relating to the detection or viewing of objects by the use of reflected waves
IPC: H04N11/00
Filed: 1943-12-03
Abstract: 617,592. Cathode-ray tubes. SPERRY GYROSCOPE CO., Inc. Dec. 3, 1943, No. 20288. Convention date, Dec. 7, 1942. [Class 39 (i)] [Also in Group XL (c)] In a radiolocation system in which a field of view is scanned by a directive radio beam and images of reflecting objects are indicated on a cathode-ray tube, the images or parts thereof are differently characterized in accordance with the time of travel to the object and back, e.g. near objects or near parts of an object such as a mountain may be red, further ones green and still further ones blue, with intermediate mixed shades of orange and blue-green. In the system shown, the beam of the display tube 17 is given a spiral movement synchronous with the transmitted beam and a segmental colour disc I is rotated in front of the screen S by a motor 86. An auxiliary cathode-ray tube 69 has a plurality of electrodes 71 ... 73 on the target area, one pair of deflecting plates 78 being fed with a saw-tooth voltage 75<1> causing the beam to traverse once for each pulse transmission a path E, Fig. 2, normally just below the electrodes, whilst the other pair of plates 79 is fed with the received pulses which deflect the ray to form peaks 81 engaging one or more of the electrodes. The electrodes 71 ... 73 are separately connected over commutator segments 92 to the grid of tube 17 during the periods when the screen S is completely covered by the red, green and blue segments respectively. Thus all reflected pulses from objects near at hand as represented by peaks engaging electrode 71 will produce red images, and similarly objects further away will produce green or blue images, or images of intermediate shades which are provided for by the oblique edges of electrodes 71 ... 73.

Title: Improvements in and relating to driving mechanism for pedal cycles
IPC: B62M1/10
Filed: 1943-12-07
Abstract: 575,427. Cycles. TALBOTT, W. Dec. 7, 1943, Nos. 20400/43 and 1425/44. [Class 136 (ii)] Means for storing and subsequently utilizing the energy that is normally wasted when a bicycle is retarded by braking, comprises an air compressor 6 drivable from the rear wheel 11 and adapted to feed a reservoir 7 ; and a turbine 8 operable by the compressed air in the reservoir to drive the rear wheel, the device being fitted within the framework of the bicycle and controlled by levers on the handle-bar. The spindles of the rotors of the compressor 6 and turbine 8 are in frictional engagement with a wheel 4. A spindle 2, one on each side of the frame, is also in frictional engagement with the wheel 4 at one end and at the other to a friction surface 1 attached to the rear road wheel. The spindles 2 may be released from engagement with the surfaces 1 by arms 3 which are operated by a handle-bar control. The reservoir 7 comprises three stages, in the second 7a of which, the pressure may be supplemented by the use of a hand pump 7b. The third stage 7c contains a spring-loaded diaphragm and safety valve and feeds a flashheated chamber (not shown) under the control of a valve operable from the handle-bars. Air from the flash-heated chamber passes to the turbine 8, the exhaust of which passes to the input of the compressor 6. (According to the second Provisional Specification, the flashheated chamber may be heated electrically by means of a dynamo.) In use, the handle-bar controls may be set to engage the spindles 2 with the surface 1 and close the air input from the reservoir 7 to the turbine. The motion of the cycle driving the compressor 6 builds up a pressure in the reservoir 7. When the desired degree of braking has been attained the spindles 2 may be disengaged from the surfaces 1. Subsequently, when required, the air stored in the reservoir 7 may be released to the turbine and the spindles 2 re-engaged to enable the mechanism to assist the rider.

Abstract: 1462737 Shaping metal powder HOMOGENEOUS METALS Inc 14 May 1975 [31 May 1974] 20451/75 Heading B5A [Also in Division C7] A shaped metal article is made by filling a plated metal shell mould with metal powder, surrounding the shell mould with a pressure transferring support medium, compacting the metal powder and shell in the support medium and then removing the compact from the support. A pattern having the dimensions of the final shaped article required multiplied by the reciprocal of the cube root of the tap density of the metal powder, e.g. "Hastelloy" (Trade Mark), is surrounded by silicone rubber which is then set to form a female mould which is removed from the pattern and filled with molten Pb-Bi. A Ni tube is inserted into the melt prior to solidification and the solidified casting is then removed from the mould and electroplated with a Ni shell 0À002-0À003 inch thick. The plated casting is then surrounded by Fe powder which is then compacted, e.g. to 70% density to form a support medium, the Pb-Bi casting being then removed by melting, the Fe powder being sintered at the same time. The cleaned cavity of shell is now filled with the superalloy powder, the assembly is canned, the can is evacuated and sealed and the assembly is then isostatically hot pressed to 100% density. The can and Fe support are then removed by machining or pickling. The support medium may alternatively be a ceramic grit, a liquid or a cast material which is plastic or liquid at the pressing temperature.

Filed: 1976-05-19
Abstract: 1511753 Elevator safety system INVENTIO AG 19 May 1976 [21 May 1975] 20688/76 Heading G3N A safety device is used, e.g., to stop elevator movement if the lift doors are not closed correctly or for a railway protection system. With the lift cage stationary and the door closed, AND gate V11 receives a binary 1 and OR gate V12 receives a 0. Line LSiO is 0, store SPO output is 0, which is inverted and provides another 1 to AND gate V11 which gives a 1 output. Hence NOR gate V13 and AND gate V15 give a 0 output, store SP11 is not set, line LSi2 is 0, AND gate V14 gives a 0 output and so does line st L thus defining an installation not switched off signal. If st L is binary 1, the installation is switched off, though a temporary disturbance does not cause switch off due to delay element ZG. On initiation of a lift journey, LSiO is made binary 1 to prove the safety circuit before the doors close. Stores SP42 and SPO are set, and inhibit line SPL inhibits car movement for the test duration. This signal then passes through the circuitry and produces a 0 on line SPL if the circuitry is functioning correctly. If faults are present in the circuitry, SPL stays at binary 1 and car movement is inhibited. The circuitry can be implemented using NOR- techniques or in MOS logic with self-blocking MOSFET's.
