Title: Improvements in electron multipliers
IPC: H01J25/76
Filed: 1936-11-18
Abstract: 485,620. Electron multipliers ; circuits. FARNSWORTH TELEVISION, Inc. Nov. 18, 1936, No. 31646. Convention date, Jan. 27. [Classes 39 (i) and 40 (v)] An electron multiplier comprises a secondary emitting cathode 1, Fig. 1, surrounding an anode 10 ; when a resonant circuit of suitable frequency is connected between the anode and cathode oscillations are set up, the electrons passing through the anode between successive impacts on various portions of the cathode surface. If the device is not self-starting an electron gun comprising a cathode 14, modulating electrode 16 and anode 20 may be used to direct a modulated stream of electrons into the space within the cathode ; the device will then act as an amplifier. As shown in Fig. 5 two such tubes may be connected in push-pull as a balanced modulator, the grids 16 being supplied in opposite phase from the oscillator 40, and in the same phase through coupling condenser 39. The frequency of the resonant circuit is chosen so that the time of flight of an electron across the tube is one or more complete periods of the oscillation. The cathode is of copper coated with aluminium, nickel, caesium or caesium oxide and may be mounted within the tube or may form part of the envelope when a watercooling jacket 42 may be added. Part of the cathode may be made photo-electric to enable primary electrons to be generated by a modulated light beam. Specifications 450,138 and 451,724 are referred to. The Specification as open to inspection under Sect. 91 describes also a form in which the time of flight of the electrons is much shorter than the period of the oscillations generated. This subject-matter does not appear in the Specification as accepted.

Abstract: 768,002. Hand-knitting. STEINHOF, K., [trading as STEINHOF APPARATEFABRIK, K.]. Nov. 2, 1954 [Nov. 4, 1953], No. 31686/54. Class 74 (2). A needle selector for patterning in handknitting apparatus comprises members 10 housed in a body formed of opposed plates 1, 2, and slidable on guides 6, 7, 8, to project from either longitudinal edge of the body. Each member 10 is formed from wire bent as shown, with an inwardly bent locating part 12 and with a gap 11 between its ends so that the resilient engagement of the part 12 between the related guides 7 and 6 or 7 and 8 is not hindered. Projecting members 10 are engaged behind the butts of needles to move the needles into operation. Since any member 10 projects from only one side of the body at a time, a setting of members corresponding to a particular pattern along one longitudinal edge of the body will also provide, along the other longitudinal edge, a setting corresponding to a complementary pattern.

Title: Improvements in and relating to the production of sound films
IPC: G11B7/00
Filed: 1936-11-19
Abstract: 485,469. Optical sound recording. KOLB, O. K. Nov. 19, 1936, No. 31708. [Class 40 (ii)] [Also in Group XL] Multiple variable-area sound tracks are recorded on a film by means of two or more separate electro-optical modulating devices and a single optical system for throwing the light from the modulating devices on to the film. The tracks may be in phase, or pushpull, or bilateral, or stereophonic, and may be "noiseless." As shown in Fig. 1, two microphones 1, 2 receiving sound from a source (not shown) are connected by separate amplifiers 11, 21 to separate oscillographs 12, 22. Light from two separate sources pass through separate optical systems 15, 25 to the mirrors 14, 24 of the oscillographs, and from thence through separate prisms 16, 26. After this, the light passes through a slit 31 and a single optical system 4 to the film 5, where two stereophonic tracks 41, 42 are formed. A switch 6 is provided between the amplifiers and the oscillograph, so that amplifier 21 may be cut out of circuit, and both oscillographs connected to the amplifier 11 to produce two similar tracks. Alternatively, the switch may be arranged to connect both amplifiers in parallel and in correct phase to both oscillographs. In another form, Fig. 2, the prisms 17, 27 throwing the light beams from the oscillographs 12, 22 to the slit 31 can be adjusted laterally, so as to cover the whole sound track of the flm 5 by the beam from the oscillograph 12 only. The adjustment of the prisms is performed by a handle 7 which simultaneously opens a switch 61 to disconnect the oscillograph 22 and replaces a single triangle aperture 18 by a double-peak aperture 19 in the incoming light beam to the oscillograph 12. Biassing systems such as described in Specifications 377,675 and 339,610 may be employed.

Title: Production of fibres or filaments by extrusion of virtually inviscid jets
IPC: D01F9/08
Filed: 1970-07-01
Abstract: 1308979 Continuous casting MONSANTO CO 1 July 1970 [2 July 1969] 31867/70 Heading B3F [Also in Division C1] To form a fibre or filament, molten inorganic material 1, such as a metal, alloy, ceramic composition, aluminium oxide or a metalloid, having a viscosity less than 10 poises, is extruded as a jet 4, e.g. of less than 50 mils diameter, into a concomitant flow of inert gas such as He or Ar to pass with the gas into an atmosphere which forms a stabilizing film on the jet by decomposing or reacting with the jet material. The inert gas is said to inhibit the growth of deposits, e.g. of oxides, in or near the extrusion orifice 2. It can relax the velocity profiles created at the orifice before film-stabilization and therefore long-bore orifices can be used. Examples are given of extrusion of Pb/Sn alloy (62/38) and Al alloy into He and then into air (for stabilization). Also referred to as melts for extrusion are Al, Ag, Au. Cu, Fe, Pb, Sn and alloys thereof, including stainless steels and carbon steel. The He or Ar passes through a port 7 into a space 5 between a plate 10 having an orifice 2 (through which the melt is extruded from a crucible 3) and a second plate 6 with an aperture 8 (which may be frustoconical) for the outflow of the gas and jet 4 into a chamber 9 of the stabilizing-film gas. Relative dimensions of the orifice 2, aperture 8 and space 5 are given. The space 5 may he machined in the orifice plate 10 instead of in the plate 6, or the assembly of plates 6 and 10 may be formed by machining the port 7, space 5, aperture 8 and a socket for the plate 10 in a crucible base and placing the plate 10 in the socket. The plates may be of alumina, magnesia, thoria, beryllia or zirconia or stainless steel or, for extruding ceramics, of molybdenum or graphite. Thr inert gas pressure and density may be varied to determine a degree of attenuation of the extruded jet 4 to control the filament diameter and the gas velocity can be increased so that discontinuous fibres, e.g. of a length/ diameter ratio greater than 5, are produced. Reference has been directed by the Comptroller to Specifications 1,153,577 and 1,197,972.

Title: Pneumatic motor of the reciprocating type
Inventor: SMALLPEICE COSBY DONALD PHILIP
IPC: F01B17/00
Filed: 1961-09-06
Abstract: 943,759. Reciprocating pneumatic motors. MARTONAIR Ltd. Aug. 28, 1962 [Sept. 6, 1961], No. 31956/61. Headings F1M and F1S. A pneumatic motor includes a piston biased in the direction to engage the head of a coacting cylinder and to cover a small exhaust port therein the heads of the piston and cylinder when in engagement with each other defining between them an annular chamber which extends up to the periphery of the piston and of which chamber the wall formed by the piston head is of substantially less area than the whole cross-sectional area of the piston head and the cylinder being provided with an inlet to the chamber for a gas under pressure to act on the piston in opposition to the bias. In operation the air pump progressively charges the reservoir and the latter delivers the pressurised air to the annular chamber 21 when the pressure in this chamber, which is acting on only a minor proportion of the piston head (i.e. the annulus 35), reaches a value at which the bias acting on the piston is overcome, the piston commences to move away from the cylinder head as soon as this takes place the annular rib 19 breaks the seal with the ring 20 and the whole area of the piston head is thereby exposed to the air pressure achieved in the reservoir with the result that the outward stroke of the piston is made suddenly and at high speed and with only a small loss of pressure through the exhaust port 34 which is then uncovered. This outward movement of the piston and the uncovering of the exhaust post causes the pressure in the reservoir to drop and the bias acting on the piston returns it to its original position until the recharging of the reservoir by the pump causes the reset outward stroke to be made. The bias acting on the piston can be applied in a variety of ways. Thus it could be a coiled compression spring, or it could be provided by applying a sub-atmospheric pressure to the exhaust port 34 or, by applying a positive gas pressure to the underside of the piston or it could be applied in any combination of these ways. The pneumatic motor can be operated in a variety of ways. One method involves limiting the maximum pressure in the reservoir to a value such that the force due to the pressure acting on the annulus 35 is of itself not quite sufficient to overcome the bias, and then momentarily to overcome the bias by admitting air under pressure through the exhaust port alternatively the motor may be fired by removing a subatmospheric pressure at the exhaust port. Other modifications (e.g. Fig. 2) are described. The motor may make a single reciprocation or operate automatically.

Title: Improvements in and relating to automatic refrigerator control apparatus
IPC: F25B49/02
Filed: 1953-11-18
Abstract: 725,267. Refrigerating. GENERAL ELECTRIC CO. Nov. 18, 1953 [Nov. 18, 1952], No. 32027/53. Class 29. [Also in Group XXXVII. A defrosting heater for a refrigerant evaporator in a cabinet is energized after a predetermined number of refrigerating periods and openings of the door occurring during refrigerating periods. The control device comprises two fixed contacts 17, 20 supplying respectively the compressor motor and the heater. Supply contacts 15, 16 are carried on the end of an intermediate arm 14 carried on a main bar 10 which is pivoted by a knife edge 12 in a groove 13 in a fixed block 13a. A U-shaped spring 22 bearing on a knife edge 24 on a bar 10 urges the bar away from the contact 17 and can be adjusted as to tension by a screw 29. A thermal bulb 33 adjacent the evaporator influences a bellows 32 which, through a finger 35 engaging the arm 10, moves the arm upon rise in temperature towards contact 17. The finger is loaded by a spring 38 interposed between a shoulder 37 and a plate 36 the position of which can be shifted to vary the controlled temperature by a cam 44 turned bv a knob 42. Knob 42 also carries a stop 44a which, by engagement with a projection 10a on the arm 10, prevents the arm moving to make the contact 17 and so prevents operation of the compressor. Each time the arm 10 moves away from the contact 17, i.e. after each refrigerating period, a pawl 51 carried by the arm moves a ratchet wheel 49 one step. Each time the door is opened, a spring 56a moves a push rod 54 forwards so that a pawl 53 moves the ratchet wheel one step provided the compressor is working. If, however, the compressor is not working, contacts 15, 17 are separated and a projection 48 on arm 10 bears hard on a cam 45 coupled to ratchet wheel 49 to brake the latter. Pawl 53 is so weak that it rides over the ratchet teeth during this braking. A justifying pawl 53a is provided. Cam 45 has a dwell 47 into which the projection 48 falls after the predetermined number of operations. This allows the contacts 16, 20 to make to energize the defrosting heater. If the compressor is working when dwell 47 comes opposite projection 48, a stud 60 on the ratchet abuts the projection so that door operations cannot advance the dwell past the projection and so cause the omission of a defrosting cycle. When the compressor then stops, the projection enters the dwell and the stud 60 can pass through a slot 61 in the projection. When the arm 10 is in the defrosting position it is held by a permanent magnet 57. Defrosting is terminated when the pressure in bellows 32 is great enough to overcome magnet 57 the position of which is adjustable. In a modification cam 45 and ratchet 49 are connected by a torsion spring and stud 60 is carried by the cam.
