IPC: H01J31/60
Filed: 1957-06-13
Abstract: 892,911. Cathode-ray storage tubes. ELECTRIC & MUSICAL INDUSTRIES Ltd. June 12, 1958 [June 13, 1957], No. 18622/57. Class 39(1) A cathode-ray storage device comprises an electron source a target storage electrode, an array of conductors extended in front of the storage electrode, so that electrons from said source can only reach the storage electrode by passing between adjacent conductors, the said conductors being connected together in cyclic order so as to form a plurality of groups of conductors each group being in front of a discrete area of the storage electrode and the corresponding conductors of all groups being connected together and no two conductors of the same group being connected together, area selecting means, i.e. scanning means, for deflecting electrons so as to direct electrons only towards one of the discrete areas and element selecting means for selectively applying different potentials to the conductors of the groups to permit the passage of electrons between selected adjacent conductors of the groups and to prevent the passage electrons between other conductors of said groups, whereby electrons from said source can only reach an element of the storage electrode selected by the combined effect of the area selecting means and the element selecting means. The potentials for unblocking an elementary area of the grid are obtained from 2 sets of 10 bus wires 15, 16 energized by a control circuit the bus-wires being connected to the grid wires so that the latter form ten interleaved groups. Unblocking of an, elementary area is then achieved by putting a positive potential on one pair of adjacent bus-wires 15 and also on one pair of adjacent bus-wires 16 the elementary area unblocked being that bounded by the two pairs of grid wires (actually a plurality of elementary areas marked x in Fig. 2 are unblocked but since the electron beam covers only one of these areas only one elemental beam area passes through). A circuit includes scanning generators and a relay tree or decoding matrix for the. incoming signals which are applied to the control grid 7.

Title: Automatic Thread-cutting Mechanism for Sewing Machines.
Inventor: SALSBURY THOMPSON GRAVES
IPC: D05B65/00
Filed: 1916-12-30
Abstract: 108,630. Salsbury, T. G. Dec. 30, 1916. Sewing - machines; stopping-gear; threadcutters; threads, controlling othermise than in stitch-forming. - In sewing-machines of the kind having automatic thread-cutting means, the latter is actuated by the continued movement of the flywheel after the stitchforming mechanism has been stopped. The thread-cutter consists of a curved hook h with a cutting-projection i at the side. The stitch-forming mechanism is stopped preferably with the loop-taker d entered about one-sixth of a revolution in the needlethread loop, and the hook h then draws out this loop f, f<1>, the tension being at this time released, and subsequently cuts the uader-thread f<2> and the strand f<1> of the needle-thread, the tension being reinstated for that purpose. The shaft h<1> of the cutter has at its rear end a pinion o which gears with a segment n on a spring-controlled lever l which is actuated by the stopping mechanism. The lever l carries a pin n<4>, which in the forward movement of the lever moves from a, notch p<2> to a notch p' over a cam surface p<3> of an arm p fast on a rock-shaft p<4> and rocks the latter to first release and then reinstate the needle-thread tension. For this purpose, the forward end of the shaft p<4> carries an arm p<5> with a cam surface p<6> which acts on the end of a rod g<6> which passes through a tubular stud g<5> carrying the tension disks, washer, and spring, and has a transverse pin adapted to move the washer against the action of the spring g<3>. In an alternative form, the cam is on one end of a lever, the other end of which has a slot-and-pin connexion with the presser-bar, and the arm p<5> is connected to the lever by a link. The stop mechanism comprises a member e slidable in a groove in the fly-wheel a and controlled by a spring. The member e has a projection e<4> and a ring j which carries a loose ring d<1>. A disk a<2>, flanged at a<3>, is secured to the main shaft a<1> of the machine, and the member d' slides between fixed guides d<2>, d<3> on the disk and has a tail piece d<5> which registers in position with a slot a<5> in the flange of the disk. Under normal running conditions, the member e is held by the controlling springs, so that the ring j i is eccentric to the shaft a<1>, the projection e<4> engages the slot a<5>, and the tail piece d<5> of the member d' is withdrawn inside the circumference of the disk flange a<3>. To stop the machine in the desired position, which is indicated by suitable marks on the member e, this member is moved against the action of its spring, thus throwing the catch e' out of engagement with the slot a<5> and projecting the part d<5> so that it is engaged by a spring catch k. This arrests the main shaft, and during the subsequent movement of the projection e<4> round the disk flange a<3> before it again engages the slot a<5>, it actuates the lever l to set in motion the threadcutting and tension-controlling devices.

Patent GB-531189-A (GB)
Title: Improvements in electromagnetically operated step-by-step devices
IPC: H03J1/22
Filed: 1939-06-29
Abstract: 531,189. Electric selectors. PHILCO RADIO & TELEVISION CORPORATION. June 29, 1939, No. 18962. Convention date, July 20, 1938. [Class 40 (iv)] An electromagnetic step-by-step device or switch comprises a rotary member or wiper having a home position to which it is urged by a spring, set by a ratchet wheel driven by a stepping magnet in response to impulses, and provided with a holding pawl operated by a further magnet which is slow-acting and remains energized during the impulse train. The ratchet wheel has an abutment which drives a further and co-axial rotary member or wiper and ratchet wheel which is held by a pawl when the first rotary member returns home, the second rotary member being returned to an initial position when the first rotary member is next operated to a pre-determined position. As described the first and second rotary members comprise switches which respectively control volume and muting, and tuning of a wireless receiver as described in Specification 531,188, [Group XL]. The driving and controlling mechanism is mounted on a U-shaped member 1 and comprises stepping and holding magnets 3,4, Fig. 1, the armatures 15, 16 of which project through apertures in the base of member 1 and respectively comprise a stepping pawl for ratchet wheel 23 and an operating member for holding pawl 32 thereof. The ratchet wheel 23 is urged to a home position (clockwise in the bottom view shown in Fig. 4) by a helical spring 25 and the armature of the holding magnet engages the pawl on one side by means of a blade spring 33 to permit it to yield during stepping. The ratchet wheel 23 has a wiper co-operating with switch bank 47, Fig. 4, corresponding to the volume control and muting switch in the above-mentioned Specification. A further ratchet wheel 24 is mounted below ratchet wheel 23 on the same stud 18 and is urged to an initial position against stop 39a by spring 38 connected to arm 37 on the ratchet wheel. The arm 37 engages the forked end of an arm 52 of the shaft of a second switch 55 which corresponds to the tuning control switch of the abovementioned Specification. The second ratchet wheel 24 is held in the last-operated position by a pawl 40 which is released by the free end of a spring 34, Fig. 7, fixed to the first ratchet wheel, when that wheel has proceeded four steps. The second wheel thereupon returns to an initial position in which an abutment 28 thereon engages abutment 27 in the first wheel so that it is subsequently moved forward with the first wheel. A punched up portion 43, Fig. 7, on ratchet wheel 24 releases the spring 34 from pawl 40 after it has released the ratchet wheel and the curved portion 35 of the spring allows it to ride over the pawl when the first ratchet wheel is released at the end of an impulse train. A circuit, Fig. 11 (not shown), comprising a gas discharge tube for controlling the magnets 3, 4 is substantially the same as that described in Specification 521,941, [Group XL].

Filed: 1974-05-01
Abstract: 1463538 Fuel elements SAES GETTERS SpA 1 May 1974 [13 June 1973] 19121/74 Heading G6C A non-evaporable getter material is activated, as by heating to 950 C. for a few minutes, before being inserted in a fuel element which has been pumped to subatmospheric pressure, preferably below 10<SP>-2</SP> torr. (By "non-evaporable getter material" is meant one which functions effectively at a temperature below that at which the material evaporates.) The activation may be by induction heating, heating by infra-red radiation or by direct contact with a heated surface and may take place in an evacuated or inert-gas-filled chamber, e.g. a glove box, to which the fuel element is also attached so that the activated getter can be placed in the fuel element immediately prior to sealing the end cap of the fuel element sheath. Alternatively, the activated getter material is placed within a sealed container having a vacuum or inert gas atmosphere and the container can then be opened within the evacuated or inert gas-filled chamber to which the fuel element is attached. The getter is removed from the container and placed in the fuel element which is subsequently sealed. The fuel element is sealed by a technique such as electron beam welding, argon are welding or laser beam welding which, due to localization of heating, does not cause the internal fuel element surfaces to reach such temperatures that they become active. The temporarily sealed off fuel element is now removed from the chamber and aged by storing at a temperature of between 120 and 250 C. under vacuum conditions. Gases and/or vapours, e.g. water vapour, released from the fuel diffuse towards the plenum chamber housing the getter where they are absorbed. The temperature is limited to 250 C. since above this the internal surfaces of the fuel element may become active and absorb some of the water vapour or other gases which have not yet been completely removed by the getter. The getter can be in the form of a sintered mass with or without a metal or graphite holder or metal rings. Preferred non-evaporable getter materials include Al-Zr alloy (preferably 16 wt. per cent Al, balance Zr), a mixture of particulate Zr with particulate graphite, and a mixture of particulate Zr with a particulate alloy of Zr and Al (as described in Specification 1,432,030). At the end of the ageing period, the fuel element is filled at a superatmospheric pressure with helium and resealed.
