Title: Improvements in or relating to television systems
IPC: H04N3/04
Filed: 1931-09-28
Abstract: 390,158. Television. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Ives, H. E. ; 32, Laurel Place, Montclair, New Jersey, U.S.A.) Sept. 28, 1931, No. 26984. Convention date, Oct. 4, 1930. [Class 40 (iii).] For a colour television system, the transmitting arrangement utilizes a non-colour record or film with longitudinal lenticular ridges which form striations on an emulsion carried by the film corresponding to different colour characteristics of the elementary region of the object or scene, and a scanning beam is broken up by the lenticular elements on the film into three beams corresponding to the colours which are directed to three photo-electric cells allocated to the colours. A film of the above type made by the " Kodacolor " process, described in the Photographic Journal, September, 1929, pp. 402 et seq., may be employed. The scanning beam from a light source 1 is focused on a lenticulated film 5 moving uniformly and continuously between a stationary slot 4 and radial slots 7 of a rotating disc 6. The three portions of the beam are arranged to pass direct to a photo-electric cell 11 and to be reflected from mirrors 9, 12 to photo-electric cells 10, 13. The amplified photo-electric currents are passed over three separate channels 17, 18, 19 to receiving lamps 23, 24, 25 associated with appropriate colour filters 26, 27, 28. The coloured beams are combined in an arrangement including half-silvered mirrors 29, 30 and the composite beam is passed through a lens 32 for direct observation or reproduction on a viewing screen 35 through a disc 33 with spirally arranged apertures. In an alternative transmitting arrangement, Fig. 3, an image of the film 5 is focused by the lens 43 on to the scanning disc 6, and the lens 44a forms an image of the apertures of the screen 8b on the screen 8a, the three beams of different colours passing to the cells 10, 11, 13, as described in connection with Fig. 1. If the film 5 be moved intermittently the scanning disc 6 has spirally arranged apertures with an angular separation between the first and last holes corresponding to the time taken for the intermittent movement of successive frames into the scanning zone. Specification 335,638, [Class 40 (iii), Telegraphs, Electric], is referred to.

Title: Improvements in or relating to the manufacture of heterocyclic bases
IPC: C07D213/10
Filed: 1939-10-06
Abstract: 534,494. Heterocyclic bases. DISTILLERS CO., Ltd., STANLEY, H. M., and YOUELL, J. E. Oct. 6, 1939, No. 27355. [Class 2 (iii)] A process for the continuous production of heterocyclic bases containing nitrogen in the ring consists in reacting in the liquid phase, at temperatures between 180‹ and 250‹C., aliphatic aldehydes and ammonia or aliphatic amines, which are mixed together in or near to the reaction zone, whereby long contact between the reactants while their temperature is below reaction temperature is avoided. The reactants are preferably supplied to the reaction zone in the form of pre-heated liquid streams which are mixed together in or near the reaction zone, and the reaction is carried out in a pressure coil immersed in a liquid bath maintained at the reaction temperature. A small quantity of an emulsifying agent, e.g. oleic acid, is preferably added to one of the reactants. Suitable aldehydes for the reaction are acetaldehyde, crotonaldehyde, butyraldehyde and simple polymers of these, e.g. paraldehyde. Methylamine is specified as an amine. In examples, pyridine bases(chiefly 2-methyl-5-ethylpyridine) are obtained by reacting paraldehyde with aqueous ammonia. Specifications 146,869, 147,000, 147,101, 332,623 and 334,193, [all in Class 2 (iii)], are referred to.

Abstract: 463,651. Making pipe fittings. WENDEL, F. B., ALBERT, H., and STAUBER, A. Oct. 3, 1935, No. 27371. Convention date, Oct. 3, 1934. [Classes 83 (ii) and 83 (iv)] Stamping.-Seamless pipe fittings or other shapings of copper &c. are made by inserting a cup 14 in the bore of a split die block 18, filling the shell with an elastic material, e.g. rubber or liquid, e.g. water or oil or sand &c. and pressing the top edge of the blank downward by the shoulder 36 of a die plunger 34, which also maintains pressure on the liquid &c. filler to prevent buckling, to cause the metal to spread into the cross bore 22. The plunger has a spring loaded valve 42 to allow excess liquid to escape and prevent the water from having any pressure other than the spring loading of the valve 42 which however is high enough to prevent buckling or wrinkling of the shell. The cross bore 22 may have stop plugs 28 which are moved outwards as 'the metal moves into the cross bores. Fig. 6 shows the second stage of pressing, after annealing, if necessary, where the bends 39, 41 are thicker where strength is most required, the dies being rounded at these parts, to facilitate this formation. The closed ends of the T are then cut off and the bores enlarged at the mouth 64, Fig. 8 by plug dies 60. Fig. 14 shows an X made with a steel plug 78 temporarily located in the bottom of the tubular blank. A Y- connection, Fig. 21, is made by reforming a T-connection, or a Y or double Y, with a small angle 86, can be pressed out by the same process in suitable dies. The fittings may also be made with one opening smaller than the others as in Fig. 18 by die pressing or by enlarging the other openings. To make asymmetrical fittings the top of the tube blank and /or the shoulder of the die may be on the skew to cause greater flow of metal in one required direction.

Title: Isolated solid state remotely controlled switching circuit
IPC: G03B21/20
Filed: 1969-05-30
Abstract: 1275613 Switching circuits; control of AC motors MINNESOTA MINING & MFG CO 30 May 1969 [31 May 1968] 27608/69 Heading H2H and H2J  A switching circuit includes a bi-directional semi-conductor device connected in series with a source and a load. A step-down voltage arrangement is connected across the source to isolate a remote switch from the source and may be connected to a pulse generator which then supplies triggering pulses to the semiconductor device. The circuit shown in Fig. 3 is adapted to control both the lamp and motor of a slide projector. Closure of a main switch 46 energizes a fan motor 48 and also the primary winding 66 of a step-down transformer 64. If now a switch 86 is closed, a pulse is applied to trigger a first triac 72 and so energize the projector lamp 70. A motor 94, which causes the slide cartridge to be advanced and slides to be placed in the projector, can be similarly actuated by closing a switch 112, triggering a second triac 96. Further ganged switches 114, 116 may be closed and these also energize the motor 94, but a solenoid 120 now operates a mechanism which reverses the direction of movement of the slide catridge. Contacts 130 open automatically when the slide-changing operation is complete. If the main switch 46 is opened while a slide is still in the projector, a circuit 136 is made to short out the triac 96 allowing the motor 94 to continue operating until all the slides are replaced in the cartridge. The triacs may be replaced by anti-parallel pairs of thyristors, and the triggering circuit may comprise either a lamp together with a photo-cell or a lamp alone if a light-sensitive triac is used.
