Title: Reeling systems
IPC: G11B5/58
Filed: 1953-10-01
Abstract: 737,061. Sound-film or tape apparatus. RADIO CORPORATION OF AMERICA. Oct. 1, 1953 [Oct. 29, 1952], No. 26947/53. Drawings to Specification. Class 40 (2). [Also in Group XVI] , In a sound and picture film apparatus, a tapered pressure roller presses the film against a drum so that an unequal pressure is applied over the width of the film to cause it to be urged laterally in one direction and prevent laterally wandering. The largest diameter part of the pressure roller is applied at edge of the film where the sound record, which may be magnetic, is located, thus reducing the tendency of the picture part of the film to be scratched or damaged by contact with the pressure roller. Furthermore, the greater pressure at the sound record edge of the film insures good contact of the film with a magnetic sound head.

Title: A new or improved machine for packing tobacco or other fibrous or powdered material into tins
IPC: B65B43/50
Filed: 1939-09-30
Abstract: 535,221. Packeting fibrous or powdered material. ROSE BROS. (GAINSBOROUGH), Ltd., and ROSE, A. G. Sept. 30, 1939, No. 26955. [Class 94 (i)] A machine for packing tobacco or other fibrous or powdered material into tins comprises holders which are brought in turn to a station at which an open-mouthed tin is inserted mouth upwards into a holder, then to a filling-station at which tobacco or other material is put into the tin through the top of the holder, then to a pressing- station at which the material is pressed down into the tin, and the packed tin is then removed from the holder. The machine comprises a table 11, Figs. 1 and 2, which carries combined tin-holders and hoppers 12 and is rotated step-by-step about a vertical shaft 13 by a Geneva mechanism 27. The empty tins 42 are placed on an inclined slide 43 and are released one at a time by pins 73, 74 on a rocking-lever 71, on to a carrier 41 which moves in synchronism with the table 11 and carries the tins below the hoppers 12. Before a tin reaches a hopper, a paper disc 94, Fig. 3, is taken from a magazine 91 by an oscillating suction device 96 from which the disc is drawn by rollers 106, 109 and fed into the tin. The next movement of the carrier brings the tin to a station 49, Fig. 1, beneath a hopper 12, and at this station a plunger 146, Figs 2 and 5, rises and lifts the tin into the lower part of the hopper where it is gripped by four shoes 165 pivoted to the lower ends of levers 158 and urged inwards by springs. Successive movements of the table 11 carries the tin to a filling-station 51 where it receives a weighed charge of tobacco through a funnel 52, Fig. 2, and to stations where the tobacco is pressed by plungers 56, 58, 61. The pressing areas of these plungers increases from one plunger to the next. A tin is supported when below the plungers 56 and 58 by a plate 64, but when below the plunger 61 it is supported by a plunger 182 which descends, after the tobacco is compressed, and allows the filled tin to be moved downwards out of the hopper 12 by the plunger. The filled tin is then transferred by a reciprocating pusher 196, Fig. 1, on to a travelling band 62 and carried to a table 63.

Title: Improvements in or relating to nuclear reactors
Inventor: LAWRENCE NATHANIEL QUENTIN
IPC: G21C7/12
Filed: 1947-10-07
Abstract: 869,598. Nuclear reactor control rods. LAWRENCE, N. Q., and GINNS, D. W. Oct. 7, 1947, No. 26978/47. Class 39(4). In a nuclear reactor, both the fuel and shut-down rods are mounted in vertical cylinders which are inserted into the moderator through channels in the shielding. Both sets of rods may be air cooled and each shutdown rod is urged into the reactor along its cylinder by compressed air. The escape of radiation from the pile interior, through the channels, is prevented by the radially stepped form of the cylinders which act as plugs. Each shut-down rod is maintained at the upper end of its associated cylinder, away from the core, by a solenoid which, when de-energised permits the rod to be forced, by compressed air, towards the lower lend of the cylinder, inside the core. The cooling air, which flows through the cylinder from the lower to the upper end may be used to return the shut-down rod to its upper position. Indicating switches are operated by the shut-down rods at the inner and outer positions, each rod consists of a steel tube filled with boron carbide powder and the outer cylinder is of aluminium. As shown, the heavy water moderator 11 is enclosed in tank I between shields 2 and is penetrated by the tubes 3, 6, 7. The inner tubes, 4, contain uranium fuel rods and have openings 5 for the flow of coolant. Each shut-down rod 14, is contained in the tube 12, 16, 21. The tubes 3, 6, 7 and 4 are formed with stepped diameters to provide radiation traps to prevent the escape of radiation from the pile core through shield 2. Similar traps are formed along tube 12, 16, 21 by stepping the internal and external radii, and by the change in character from rod 14 to piston 13, to interrupt the linear air paths. Specification 821,931 is referred to.

Title: Improvements in or relating to the drying of clay products and other goods
IPC: F26B21/02
Filed: 1924-11-12
Abstract: 246,935. Brown, A. E. Nov. 12, 1924. Air and gases, controlling direction of flow of. -Clay products &c. to be dried are subjected to vertical currents of air or gas of increasing temperature and decreasing humidity and volume. As shown, the products are placed within a series of longitudinal compartments C having flues E, F which communicate through damper-controlled openings with flues H, K, L. The air passes from the flue H into one or more of the flues E, downwardly through the corresponding chambers, and to the flues F from which it passes to the flue K which communicates both with the atmosphere and other chambers through which the air passes upwardly to the flue L. From the flue L, the air passes either to the atmosphere or downwardly through further chambers to an exhaust flue K<2> adjacent to the flue K. The flues H, K, L can be duplicated and the air may be passed in the opposite direction through the chambers. By decreasing successively the number of chambers through which the air passes at each change of its direction, the products are subjected to air of increasing temperature and decreasing humidity and volume. Specification 24188/98 is referred to.

Title: Improvements in carrier wave modulating systems
IPC: H03C1/20
Filed: 1935-10-02
Abstract: 453,732. Modulating systems. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. Oct. 2, 1935, No. 27202. Convention date, Oct. 4, 1934. [Class 40 (v)] Modulation is effected according to the floating-carrier method, by using Class B amplifiers for the modulating-voltage, and by utilizing the variation in their direct current resistance to alter the grid or platevoltage of the carrier-wave amplifier, and so to raise or lower the carrier level according to signal volume. In the Figure the microphone 18 is connected through an amplifier 20 and transformer 21 to a pair of push-pull Class B amplifiers 23. The carrier source 10 is coupled to an amplifier valve 13 which passes no plate current until its grid is excited. The plate circuits of the valves 23, 13 are connected in series with each other and with the supply source 32. When the microphone is inactive the valves 23 have high D.C. resistance and there is only a small fraction of the voltage of the source 32 applied to the platefilament circuit of the valve 13, which consequently passes only weak carrier pulses to the aerial. The level of carrier wave output in the absence of signals may be adjusted by biassing the valves 23, or by inserting a resistance 42 across the valves 23 in parallel with the condenser 29. As the signal grows in volume the carrier pulses to the aerial circuit are proportionately strengthened. At the same time the carrier output is modulated in the rhythm of the signal on account of the inclusion in the series circuit of the secondary coil 28 of the output transformer of the amplifiers 23. In a modification, the valve 13 has an independent plate supply, and the plate current of the valves 23, together with the signal current arising in the secondary coil 28, flow through a resistance situated in the grid circuit of the carrier amplifier 13.

Title: Improvements in the manufacture and production of condensation products from hydrogen sulphide and acetylene
IPC: C07G99/00
Filed: 1934-09-24
Abstract: Acetylene and hydrogen sulphide are brought to reaction in a liquid solvent at atmospheric or raised temperature and pressure in the presence or absence of a catalyst, which may be a sulphide or polysulphide of an alkali, alkaline-earth or heavy metal or of ammonia, or an ammonium or metal salt which is converted into a sulphide by the action of hydrogen sulphide, e.g. a salt of copper, iron or nickel.  Specified solvents are the polyhydric alcohols and their ethers still containing a free hydroxyl group, such as mono-, di- and tri-ethylene glycol, propylene glycol, trimethylene glycol, 1 : 3-butylene glycol, glycerol, polyglycerols, and diethylene glycol monoethyl ether; water and dioxane are also specified.  Pure or dilute acetylene may be used. The course of the reaction depends on the conditions; thus, (a) by treating a solution of hydrogen sulphide with acetylene under pressure, polymerization products of thioacetaldehyde, particularly a -trithioacetaldehyde, are mainly obtained, whereas (b) by leading a mixture of hydrogen sulphide and acetylene through a solvent containing a small proportion of a catalyst, ethyl mercaptan, vinyl ethyl sulphide, ethane dithiol diethyl ether (CH3CH2SCH2CH2SCH  CH3), or mixtures of these compounds are obtained, according to the proportions taken.  An example is given of a process of type (a) in which an aqueous or dioxane solution of hydrogen sulphide, preferably containing potassium hydrosulphide, is treated with acetylene at 100 DEG  C. and 10--20 atm. pressure.  Examples are given also of processes of type (b) in which mixtures of acetylene and hydrogen sulphide are passed at 120--130 DEG  C. into diethylene glycol containing potassium hydrosulphide.
