Title: Image dissector and method of electron beam analysis
IPC: H01J31/42
Filed: 1935-02-15
Abstract: 452,037. Television. TURNER, F. S., 2576, Green Street, San Francisco, U.S.A. Feb. 15, 1935, No. 4975. [Classes 39 (i) and 40 (iii)] An electronic discharge of varying density over its cross section is accelerated non- uniformly, and deflected cylically, and successive portions are selected which have travelled in a rectilinear path. An optical image is focused on a flat photo-electric cathode 14 to produce the electronic discharge which is attracted by a tubular anode 25 so positioned away from optical focii that it does not obstruct the optical image. The electrons are focused in the plane of a minute aperture 27 in the tube 25 by a solenoid 41, and are swept over the aperture by vertical and horizontal scanning-coils 36, 39. The selected part of the discharge passes through the aperture to an inner anode 29. The selecting-anode 29 is connected to a high potential through a resistance, across which the signals are developed, and the collecting- anode 25 is connected to a less high potential, Fig. 7 (not shown). Alternatively, the connections to the anodes are reversed, and the signals are produced by secondary electrons attracted to the inner wall of the collecting- anode, Fig. 8 (not shown). British Specifications 368,309, 368,721, and 452,109, and U.S.A. Specification 1,970,036 are referred to.

IPC: H01R4/62
Filed: 1966-02-04
Abstract: 1,111,344. Connecting cable to terminals; preventing corrosion. BRITISH INSULATED CALLENDER'S CABLES Ltd. 3 Feb., 1967 [4 Feb., 1966; 8 Feb., 1966], Nos. 5064/66 and 5474/66. Heading H2E. The risk of corrosion due to the difference in electromotive potential between an aluminium conductor and a copper or brass terminal is reduced by inserting between the conductor and terminal an intermediary member made of, or at least an outer skin of which is made of, a metal which lies between copper and aluminium in the electromotive series or of an alloy whose main constituent is such a metal. In the embodiment shown in Fig. 1, the intermediary member takes the form of a readily deformable copper tube 4 which is tin-plated on its inner and outer surfaces. The tube is crimped around the ends 2 of bared aluminium wires 1 and inserted into the socket 7 of a copper or brass terminal 6 and held therein by a pinching screw 8. In another embodiment a tube of copper tin-plated inside and out is placed around a threaded binding part (16, Fig. 2, not shown), the bared end of an aluminium conductor being clamped between washers of the same material as the tube. In a third embodiment (Fig. 3, not shown), the ends of two aluminium conductors are scarfed such that together they form a conductor of roughly circular cross-section which is inserted in a tin-plated copper tube which is then inserted in a malleable sleeve connector, the sleeve then being crimped around the tube and conductor. One end of the tube may be closed as at 5, Fig. 1, such that the ends of the conductors are prevented from passing right through the tube and being bent over to contact the terminal.

Title: New and improved granular or pelletized products having properties which are extremely valuable in compounding rubber
IPC: C08K9/08
Filed: 1948-02-23
Abstract: A granular or pelletized free-flowing product which may be used in rubber compounding is obtained by adding a synthetic rubber latex or solution to a dry finely-divided pigment such as carbon black or zinc oxide, agitating the mass until it is converted into discrete granules or pellets and then drying.  The synthetic rubber may be neoprene, butyl rubber, a copolymer of butadiene with acrylonitrile or styrene, or an organic polysulphide.  About three per cent of a wetting agent such as a sodium salt of an alkyl sulphonate, a monosodium aryl sulphonic acid or an alkylated naphthalene sulphonate is preferably added to the latex before the pigment.  The latex may be added to channel or furnace black in a rotary baffle to produce particles of approximately 1/8 to 1/60 inch in diameter which may then be dried at 160 DEG  C. Specifications 270,658, [Class 70], 404,452, [Group III], and 622,518 are referred to.  The Specification as open to inspection under Sect. 91 comprises also the use of sulphur as the pigment, and the addition of coal tar oil, pine tar and asphalt to the mixes.  This subject-matter does not appear in the Specification as accepted.
Patent GB-1135312-A (GB)
Title: Improvements relating to switching arrangements for yarn winding machines and other textile processing machines
IPC: B65H63/00
Filed: 1966-02-07
Abstract: 1,135,312. Yarn cleaners. ZELLWEGER Ltd. 7 Feb., 1966 [19 Feb., 1965], No. 5280/66. Headings DID, D1F and D1J [Also in Division H1] A switching arrangement for auxiliary units controlled upon operation of an electronically operated yarn cleaner on winding machines, includes a reed switch that is arranged in, and is adapted to be actuated by, a stray magnetic field of the yarn cleaner, and has contacts which make and break the circuits of the auxiliary units. In Fig. 1 a magnetically operated reed switch 10 has its contacts closed by the magnetic field B1 produced by a parmanent magnet 11. When a yarn fault has been cleared and the yarn tension has risen to a predetermined value, the switch 14 closes to energize solenoid 12. Solenoid 12 weakens the magnetic field B1 but not sufficiently to cause the reed switch to open. When a yarn fault is found an electromagnet 7 operates to cause a cutter 6 to sever the yarn 1, and the stray magnetic field B3 from the electromagnet 7 then weakens the field on the reed switch 10 sufficiently to permit the reed switch to open. As a result, the motor 4 is de-energized and a yarn brake 3 stops revolving. The cutting of the yarn 1 causes the feeler 13 to swing outwardly and so open switch 14 and de-energize solenoid 12. The impulse required to cause the cutter 6 to operate is of short duration after which the electromagnet 7 is also de-energized. This leaves the reed switch 10 under the sole control of the field B1 of the magnet 11 which, on its own, is sufficient to re-close the reed switch contacts. In Fig. 9 (not shown) the solenoid 12 is replaced by a permanent magnet (17) carried by an arm rigid with the feeler 13, the magnet (17) moving to a setting in which it weakens the field of the permanent magnet 11 whilst there is tension in the yarn 1, but swings away when the yarn is cut, to a setting in which the magnet (17) does not weaken the permanent magnet 11. Fig. 6 (not shown) illustrates how a lamp (16) can be associated with each reed switch 10 and is extinguished up when the yarn cleaner of its associated machine has operated. A drive for the winding spindle is switched off by a contactor when the yarn cleaner responds.

Abstract: 1450100 Hydraulic actuators TOKICO Ltd 19 Oct 1973 [23 Oct 1972] 05302/76 Divided out of 1450099 Heading F1D [Also in Division F2] An actuating-force generating-device comprises a multi-stage cylinder body 1 having a plurality of cylinders 2, 3, of different diameters and arranged in series, a plurality of pistons 4, 6, the same in number as the cylinders and slidable respectively therein, a piston-rod 8 fixed to the foremost piston 4 and having an actuating end projecting from the forward end of the cylinder body 1, a container 12' provided at the rear end of the cylinder body, a fluid port 19 or 20 in the forward end of each cylinder and intended for introducing hydraulic fluid or discharging it, one or more connecting rods 16 inter-connecting the pistons, and resilient means (e.g. compressed gas) within the container 12' and adapted to urge the rearmost piston, and thereby the piston-rod 8, forwardly. Each of the fluid ports 19, 20 may be selectively connected to a source of hydraulic fluid under pressure such as a pump and a tank (not shown) through electromagnetic valves (not shown). Preferably a vehicle brake is actuated by pistonrod 8. In operation, for normal running, both chambers 11, 14 to the left of pistons 4 and 6 respectively are pressurized, the brake being thereby released. When a slow stop for the vehicle is required, the electromagnetic valves are actuated to permit fluid to flow to the tank rapidly from one of the chambers 11, 14 and at a restricted rate from the other one, so the piston-rod 8 is moved relatively slowly to the left by the gas under pressure in container 12'. When a sudden stop is required, both chambers 11, 14 are evacuated rapidly. An alternative use for the invention is in a press machine.

Abstract: 1,094,323. Removing metal by electron beams. UNITED AIRCRAFT CORPORATION. Feb. 9, 1965 [April 27, 1964], No. 5597/65. Heading B3V. [Also in Division H1] A film capacitor is deposited on an e.g. ceramic or glass substrate by vacuum deposition of a first conductive layer of e.g. aluminium, an overlying layer of e.g. silicon oxide and a second conductive layer of e.g. aluminium; the depositions being masked so that the layers overlap each other. Contact pads are provided centrally of one pair of opposed edges and staggered about the centre line of another pair of such edges to contact respectively the first and second conductive layers, and after annealing and cooling the capacitor is placed on a movable table 26 of an electron beam scribing machine wherein a beam from a negatively charged heated cathode 32, accelerated in vacuo by an earthed anode 36 and controlled by bias control 44 on electrode 42, is focused by magnetic lens 40 on the face of the capacitor. A tape control 50 pulses the electrom beam and also controls the energization of deflection coils 52, and/or a motor 54 deflecting the table, so that the beam traverses the capacitor face to thermally divide the multilayer structure so that two independent capacitors are formed on the substrate. The beam focus may also be controlled from the tape. Thereafter the tape control reduces and defocuses the beam and motivates the table and beam deflections to cut back the edges of the divided second conductive layer, and during pulse intervals the capacitance of each unit is measured by monitor 56 by comparison with a standard 58, and when the desired values are reached a signal to the tape control arrests the operation. The capacitor may be divided into more than two units, and the tape control may be substituted by a digital store with analogue readout. A laser beam may be used instead of an electron beam.

Title: Improvement in apparatus for thermally desurfacing metal bodies
IPC: B23K7/06
Filed: 1941-05-01
Abstract: 546,733. Cleaning metals. LINDE AIR PRODUCTS CO. May 1, 1941, No. 5645. Convention date, May 11, 1940. [Class 82 (ii)] [Also in Group XXII] A machine for desurfacing a steel slab &c. S comprises a roll conveyer 20 for the slab, a blow pipe head H arranged below these to project a sheet of gas against the lower face, and pneumatic means for raising and lowering the head. The head H has passages 90, Fig. 13, for preheating gas, e.g. acetylene and oxygen mixed in blow pipes 92, passages 32, 85 for cutting oxygen, and 101 ... 115 for cooling water and may have a wear-resisting metal surface 117 to engage the slab. It is guided in its vertical movement by rollers 59, 63, 67, Fig. 2, to engage rails in pillars J, J' with enough freedom to allow it to tilt with irregularities in the slab. The lifting cylinders 25 are mounted to swivel in both directions. The air used to lift the head and press it against the slab has its pressure kept constant by regulators 179, an electrically - operated relief valve 191 controlled by a pressure device 193, and a reservoir 189 with safety valve 190. The air is admitted to the cylinders 25 by a valve opened by a solenoid 185 energized by a hand - controlled switch and as the head rises it may engage switches 171 to turn electrically-operated valves to supply the pre-heating gases. A switch is then operated by hand to open a solenoid-controlled valve to admit cutting oxygen to the nozzles 81 and start a motor which drives the rolls 20. When the rear of the slab S passes a spring-pressed arm 204, Fig. 1, this closes a switch 209 which, acting through a time-delay device, closes the valve 185 and positively opens exhaust valve 191, to lower the head and this may operate the switches 171 to cut off the preheat gases, the oxygen being cut off subsequently. All the switches may be operated in sequence by a hand-rotated drum. The slab may then be turned over and traversed to the left so that the other surface can be treated. The slab may be held down on the rolls 20 by a roll 196. A buffer 212 and, if desired, a switch may be arranged to be engaged by the head if this is tilted to the right by the moving slab. the switch being arranged to stop the rolls 20 or lower the head. The material removed from the slab is received by a shoot 214. Buffers 199, Fig. 2, may be arranged to receive the lowered head. Before commencing the desurfacing operation the head is adjusted laterally of the slab by a motor 42. Fig. 3, gearing 41, 38, 37 and wheels 33, Fig. 1, running on rails R. The movement is indicated by a pointer 161, Fig. 2, actuated by a roller 164 and fixed incline 165, and limited by a stop 168. The nozzles 81 may be blanked off in pairs by hand-operated valves. The cooling water may be heated to a desired fixed temperature and operate a pressure indicator arranged to sound an alarm &c. or switch off the nozzles, if its pressure falls. The machines may be used with another desurfacing machine, e.g. as described in Specification 534,174, [Group XXII].
