Title: Improvements in or relating to methods and apparatus for mounting and firing getters
Inventor: WOLFSON ANTHONY SAMUEL
IPC: H01J7/18
Filed: 1950-07-05
Abstract: 682,555. Discharge apparatus. CINEMA-TELEVISION, Ltd. July 4, 1951 [July 5, 1950], No. 16800/50. Class 39(i) A mounting for a plurality of getters adapted to be fired within a vacuum tube by an induced high frequency current is of such construction that getters can be fired in succession at any desired time intervals by current induced from a source, the position of which is the same for all firings. The mounting may comprise a helix 14 to which getter wires 15-20 are attached at spaced intervals, the other ends of the getter wires being connected to a support 21. On inductive heating the getter wires 15 and 20 carry the greatest current and can therefore be fired before the others; after firing the heating is increased until the wires 15 and 20 fuse. After the wires 15 and 20 have fused the wires 16 and 19 may be fired and fused in the same way, and so on until all the getters have been fired. In a modification, Fig. 4 (not shown), one end of the helix 14 is connected to the support 21 so that the getters fire singly in turn instead of in pairs. In a further modification, Fig. 1 (not shown), the helix is replaced by a broken ring. The mounting may be arranged in the neck of a cathode ray tube or in a projecting stem mounted on the bulb of a cathode ray tube.

Title: Improvements in the manufacture of chocolate
IPC: A23G1/10
Filed: 1947-06-26
Abstract: Chocolate paste is treated in substitution, at least partially, for the usual conching operation, by spreading it centrifugally into a thin exposed layer, atomising the layer by centrifugal projection, again spreading the paste into a thin layer, and finally laminating it between two relatively moving surfaces. Cocoa mass and cocoa butter are mixed by rotary blades 26, 27 in a vat having walls 22, 23 between which steam or hot water is passed.  Cover 24 is <PICT:0663033/III/1> then closed, and a pipe 38 is coupled to a vacuum pump.  The mixture is lifted by a rotating screw 33 through a tube 31 to a homogenizer comprising two cones 4 and 5 which are rotated at, say, the same speed in opposite directions.  After flowing over the cone 4 in a thin layer, the mixture is projected in atomized form on to the cone 5, over which it again flows as a thin layer and is projected on to a stationary cone 13.  The mixture is then subjected to crushing and re-agglomeration between cone 13 and a rotary cone 14, and then returns to the vat to be recirculated at least two or three times more.  Blades 26, 27 may be kept rotating to assist circulation.  After the machine has been stopped and the cover 24 removed, the blades 26, 27 may be restarted to stir the mixture. The process may be worked by separate components, comprising a mixer, a pump and a homogenizer, connected in a closed circuit by piping. In a further embodiment, two preliminary mixers are used alternately to feed three homogenizers arranged in series and followed by a final mixer, the chocolate paste being transferred from one apparatus to the next by, for example, a worm-type conveyor.  The homogenizer may be substantially similar to that described in Specification 640,564. Specification 461,772 also is referred to.

Patent GB-679725-A (GB)
Title: Improvements in or relating to cathode ray tubes
IPC: H01J31/06
Filed: 1949-06-29
Abstract: 679,725. Cathode-ray tubes. WESTERN ELECTRIC CO., Inc. June 29, 1949 [July 3, 1948], No. 17204/49. Class 39 (i). [Also in Group XL (c)] The pulse code modulation apparatus described in Specification 637,820, in which code groups of pulses are produced from samples of a complex input wave, is modified by forming the beam into a narrow sheet and using the input signal to deflect the beam to the code position on the target representative of the magnitude of the signal so that each complete group of pulses is produced simultaneously in separate output leads connected to targets 21 ... 25. Beam forming and focusing electrodes 12, which may alternatively be electromagnetic means or a combination of electrostatic and electromagnetic means, form the electrons into a thin sheet. The D.C. potentials applied to deflecting plates 13, 14 may also assist in the focusing of the beam. The electrodes may have slit-like apertures to give a cylindrical lens effect to assist in this focusing action. The coding electrode 17 has five rows of apertures 31 ... 35 arranged so that the code groups of pulses are formed in accordance with the binary system. The beam is deflected over the coding electrode 17 by means of deflecting plates 13, 14 to which the complex wave samples are applied. The plates may be replaced by coils, or a combination of plates and coils may be used. The lower end of plate 17, corresponding to minimum amplitude of signal, may be extended downwards so that no output results for any signal whose amplitude is less than a predetermined minimum value. Some of the apertures may be elongated in the direction of deflection, e.g. at the centre of the plate, Fig. 2 (not shown), to suppress noise or at any other intermediate position for limiting, clipping, compression or expansion of the output. As shown in Fig. 1, the end apertures may be elongated so that the same code pulse group results from abnormally large signal samples as for maximum signal samples within the normal amplitude range. The apertures may become progressively larger or smaller as the signal amplitude increases to give " compression " or " expansion " of the output. The apertured plate and collecting electrode structure could be replaced by a suitably shaped group of collecting electrodes. It is stated that any number of " signalling conditions " may be provided, i.e. a number other than two corresponding to pulse and no pulse, and any number of rows of apertures other than five may be employed. The collector electrodes 21 ... 25 may or may not be secondary emissive. In order to prevent the beam striking the coding plate between two rows of apertures an additional set of apertures 36 is provided between the other rows of apertures and is associated with a collector 26 connected by a feedback path to an auxiliary pair of deflecting plates 15, 16. The feedback path may include amplifying and centring devices. Specifications 651,520, [Group XXXIX], and 653,298 also are referred to.

Title: Improvements in hydraulically actuated variable pitch propellers
IPC: B64C11/38
Filed: 1957-06-04
Abstract: 820,074. Variable-pitch propellers. UNITED AIRCRAFT CORPORATION. June 4, 1957 [June 14, 1956(2)], No. 17691/57. Class 114. In a variable-pitch propeller with mechanism for locking the blades against pitch change the outlet from a passage 42, for transferring oil to a chamber 44 in front of a pitchchange piston 18 to increase the propeller pitch, is closed by a centrifugally operated valve 64 when overspeed conditions arise the flyweights 62 of the centrifugal governor operating against a valve spring 74. Soon after this closure, a bleed valve 52, also centrifugally operated, cuts off communication between the chamber 44 and the corresponding chamber 46 behind the piston 18 to lock the pitch. The pressure fluid can leak behind the valve 52 to assist in its closure. To feather the blades, pressure oil is introduced into the passage 42 to open the valve 64 against the pressure of a pre-stressed spring 68 inside the spring 74. Should the pressure in the passage 42 recover of itself, the valve 64 opens and normal operation is resumed. Quick movement to the reverse position for braking can be effected by passing pressure oil from the chamber 46 behind the piston 18 through a slot 112 and port 114 to a chamber 116 behind a piston 110 adapted to displace a sleeve 92 to open the valve 64, the piston simultaneously withdrawing a wedge 98 from low pitch stops 100 to permit a flange 102 on the piston 18 to ride past them. Excess pressure building up behind the piston 18 in the chamber 46 is relieved by a surge valve 121 on the rear end of the passage 42, this valve which normally closes communication between passages 38, 40, leading from the low pitch and high pitch sides of the piston 18 respectively, being opened by the pressure acting on differential areas of a sleeve 122 constituting the valve. Specifications 607,856 and 766,621 are referred to.
