IPC: G03C7/388
Filed: 1955-06-24
Abstract: 793,554. Photographic materials. IMPERIAL CHEMICAL INDUSTRIES, Ltd. June 13, 1956 [June 24, 1955], No. 18280/55. Class 98(2) A gelatin layer of a light-sensitive photographic material is formed by oating on a substrata or support a solution containing 10 to 40 per cent by weight of gelatin, the solvent being an aqueous mixture containing at least 20 per cent by weight of a volatile, water-miscible organic solvent, and drying the coating to remove at least some of the solvents. The layer may be a subbing layer such as one containing baryta or titanium dioxide, or a filter, antihalation, overcoat, separation or lightsensitive silver halide layer. The organic solvent may be methanol, ethanol, propanol, 2-ethoxyethanol, acetone or dioxan. A light-sensitive emulsion may be prepared by precipitating silver halide in aqueous gelatine, ripening and adding more gelatin if desired, then preipitating the emulsion by adding a water-miscible organic solvent or an electrolyte. The precipitated emulsion is then redissolved in water or aqueous methanol and reprecipitated one or more times. Finally, the dried emulsion is redissolved in the solvent mixture for coating, if necessary after further ripening and the addition of the usual adjuvants. Emulsions for coating on paper need not be precipitated to remove excess salts, but prepared in aqueous alcoholic gelatin and coated, if necessary after the addition of more gelatin and the usual adjuvants. The supports for the photographic materials may be paper, glass, cellulose triacetate or polyethylene terephthalate. Examples are given of the preparation of bromide papers, chloride paners (from sodium chloride and silver nitrate with a trace of rhodium chloride), panchromatic negative emulsions, three layer colour materials wherein each emulsion layer and the yellow filter layer are coated according to the invention, and of non-sensitive separation, supercoat, and antihalation gelatin layers.

Title: Improvements in or relating to high frequency electrical transmission lines
IPC: H01P3/04
Filed: 1931-06-25
Abstract: 379,796. High frequency transmission lines. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Lindenblad, N. E. ; Port Jefferson, Long Island, New York, U.S.A.) June 25, 1931, No. 18409. Convention date, June 25, 1930. [Class 40 (v).] A high frequency transmission line is suspended or supported by attachment to a suspension device (which need not be insulated) at a point at the middle of a symmetrical loop which is one or an odd plurality of half wave-lengths long. The invention is designed to overcome insulation difficulties with high frequency lines the two conductors of which are closely adjacent to eliminate radiation, and utilizes the fact that a U-shaped conductor one half wave-length in length presents substantially infinite impedance to the working frequency, and its centre or voltage nodal point may be safely earthed without loss. Fig. 1 shows a high frequency input 2 supplying an output circuit 10 over transmission lines 4, 6, 8. Lines 4, 8 are tapped on line 6 at points #/4 distant from short-circuiting strips 12, which are at voltage nodal points and may be secured to supports 24, 20. Line 6 may be supported at intermediate points 42, 421 by similar connections 36, 38, 36<1>, 38<1> with short-circuiting strips 40, 40<1>. Fig. 2 shows a similar method applied to a bent transmission line C, D, the interconnecting conductors 56 being tapped on to lines C, D at points #/4 distant from shortcircuits 46, 48.

Title: Improvements in the manufacture of metallic titanium
IPC: C22B34/12
Filed: 1948-07-08
Abstract: 638,840. Extracting titanium. BRITISH ALUMINIUM CO., Ltd., and SAUNDERS, L. July 8, 1948, No. 18423. [Class 82(i)] A process for the production of metallic titanium by reduction of titanium tetrachloride with molten magnesium at a temperature of about 750‹C in a vacuum or inert atmosphere is characterized in that a large part of the magnesium chloride produced is separated from the titanium, e.g. by draining, while the latter is still contained within the reaction vessel and the magnesium chloride is still molten. This separating operation may be accelerated by lowering the viscosity of the molten magnesium chloride, e.g. by raising its temperature to about 850‹C during the operation of draining. The remaining titanium metal may then be cooled and purified, e.g. by washing to remove any magnesium chloride adhering thereto. Apparatus for carrying out the reaction comprises a reaction vessel 1 having a flat base 1a and a tightly fitting lid 2 adapted to be clamped in position. A pipe 6 extends through the lid in a gas tight manner and is connected to a vacuum pump and a supply of inert gas. A second pipe 7 fitted in a gas tight manner in the lid has a cooling water jacket and means for supplying liquid TiCl 4  through a sight feed 11. A tube 13 passes through and is slidable in a gland 12 and contains a thermocouple in its closed lower end which is normally located in a cylindrical vessel 14. A collar 15, slidably mounted on tube 13, carries radial arms 16 which engage in bayonet slots 17 at the upper edge of vessel 14. Movement of this collar is restricted by a second collar 18 rigidly fixed to tube 13, thus ensuring that raising of the tube 13 will result in lifting of vessel 14. This lifting is effected by lever 21 which engages pins 19 on tube 13. Vessel 14 has a flat, perforated bottom which closely fits the bottom of vessel 1. After completion of the reaction, raising of vessel 14 allows draining of liquid magnesium chloride through the perforated base into the vessel 1.

Title: Improvements relating to inverters for changing direct current to alternating current and including arc discharge devices
IPC: H02M5/42
Filed: 1938-06-21
Abstract: 516,140. Converting D.C. to A.C. ALLGEMEINE ELEKTRICITATS-GES. June 21, 1938, No. 18457. Convention date, June 21, 1937. [Class 38 (ii)] In an arrangement for converting D.C. to A.C. comprising discharge devices having ignition control, short-circuiting of the D.C. circuit on cessation of the ignition control is avoided by the provision of means which causes an increase in amplitude of the alternating component of the short-circuit current sufficient to reduce the current momentarily to zero to enable the discharge device operating to become non-conductive. This is effected by adjusting the inductive and capacitative elements Dr<1>, Dr<2> and CL, Fig. 1, on the supply side of the inverter to be resonant at the frequency of the A.C. network being supplied. In the form shown, the supply to the inverter W is from a rectifier G. In a modification the inductance in circuit is larger than is necessary for resonance so as to give increased smoothing and is designed so that the. inductance is reduced to the correct value for resonance by the short-circuit current flowing. The Specification as open to inspection under Sect. 91 states that the circuit cut-outs should be adjusted so as not to respond to momentary increase in current during the extinguishing operation. This subject-matter does not appear in the Specification as accepted.

Abstract: 772,365. Electric indicating systems. SMITH & SONS (ENGLAND), Ltd., S. June 24, 1955 [June 24, 1954], No. 18590/54. Class 40 (1). [Also in Groups XVI and XIX] Recording-apparatus comprises a plurality of similar signal transmitters 6-11, a receiver 21 and a control signal transmitter 17-20, the transmitters and receiver all being of the resultant field type, means 6s . . . 11s to connect the receiver sequentially to the signal transmitters 6-11 and to the control transmitter 17-20 after each such connection and means for causing a marking member to make a distinctive mark on a travelling record sheet when the receiver 21 is connected to a signal transmitter 6-11. A synchronous motor 26 rotates a cam 25 and in each revolution thereof a pin 24 advances a Geneva wheel 23 a twelfth of a revolution so that pins 6f-11f actuate in sequence mercury switches 6s-11s to energize in turn the relays r associated with the transmitters 6-11 which are thus connected in turn over the lines 12, 13, 14 to the receiver 21. The switches 6s-11s operate at equal intervals of time and an interval elapses between each during which a relay 16 is actuated to connect the control transmitter to the receiver 21 whose rotor drives through reduction gearing a pointer 22 which thus comes to rest at a neutral position, preferably central, as determined by the tapping 20 of one of three similarly valued triangularly connected resistors 17, 18, 19. When e.g. the transmitter 6 is connected to the receiver 21 as shown the pointer 22 moves from the neutral position to a position corresponding to the position of the brushes h, j, rotated in accordance with information to be transmitted, in engagement with a toroidal stator winding g. In each revolution the cam 25 actuates a chapper bar 33 to move the pointer 22 towards a roller 54 to mark a record sheet 34 through an ink ribbon 41. The pin 24 on the cam 25 also advances a twelve-lobe Geneva wheel 28 to drive a cam 48 which co-operates with a follower 47 to tilt a frame 44 carrying the ink ribbon mechanism to move transversely a 6-colour ink ribbon to provide a record of characteristic colour for each transmitter. As the frame 44 tilts a roller 50 coacts with a slotted bracket 49 to drive through link work (not shown), gearing 51 to move the ink ribbon longitudinally. The record sheet 34 is motor-driven through a clutch 37 and can be adjusted through a knob 38.
