Title: Organosilicon resins
IPC: C08G63/695
Filed: 1956-05-22
Abstract: Resinous copolymers suitable as casting resins consist essentially of the reaction products of mixtures of from 24.9 to 74.6 per cent (by weight] of a vinylic compound, from 24.9 to 74.6 per cent of an unsaturated polyester resin and from 0.5 to 30 per cent of <FORM:0801529/IV (a)/1> wherein R is a monovalent saturated or unsaturated hydrocarbon radical, X is an alkoxy or hydroxy radical, n has an average value of from 1 to 2 inclusive and m has an average value of from 0.03 to 3 inclusive.  The vinylic resins (monomers or polymers) specified are vinyl chloride, vinylidene chloride, acrylonitrile, vinyl alcohol, styrene, a -methyl styrene, chloro styrene, vinyl toluene, vinyl naphthalene, ethyl-vinyl benzene and vinyl acetate, and may also contain (preferably less than 10 mol. per cent of the total vinylic resin) divinyl compounds such as divinyl benzene. The polyester resins used are the reaction products of polyhydric alcohols and unsaturated dicarboxylic acids with or without other polycarboxylic acids, e.g. the reaction products of glycerine, and phthalic and maleic anhydrides, ethylene glycol and adipic and fumaric acids, propylene glycol and fumaric acid, tripropylene glycol and maleic anhydride, propylene glycol, sebacic acid and maleic anhydride, and propylene glycol, dimethyl terephthalate and dimethyl fumarate.  The organosilicon compounds used may also be monomeric or polymeric, e.g. alkoxysilanes of the formula RnSi(OR1)4-n, silanols of the formula RnSi(OH)4-n and partial condensates thereof.  The reactants may be reacted in any order, but preferably the organosilicon compound is reacted with the polyester resin and the resulting product is then reacted with the vinylic resin. Plasticisers, stabilizers and fillers, e.g. silica, glass, asbestos, alumina and titania, may be added.  In a typical example, the polyester obtained by reaction of ethylene glycol, adipic and fumaric acids was reacted with a methoxy methylphenylpolysiloxane, and the resulting product after dilution with styrene containing t-butylcatechol as inhibitor, was mixed with a styrene solution of a polyester obtained by reaction of propylene glycol, adipic and fumaric acids, and polymerized by heating with t-butyl perbenzoate. Specification 759,197 and 766,627 are referred to.

IPC: A47F5/00
Filed: 1936-03-14
Abstract: 471,323. Changing signs or display. CO-OPERATIVE WHOLESALE SOCIETY, Ltd., and FOULKES, T. E. March 14, 1936, No. 15952/37. Divided out of 470,516. [Class 3 (i)] In front of a background a displaying articles, one or more panels b carrying further articles are mounted to move parallel to the background, so that by shifting the panels all parts of the background can, in turn, be exposed to view. Fig. 3 shows a single row of panels b, but any number of rows may be provided. Projecting over the front of the sign is a canopy e through which light from interior lamps shines on the panels and background. When the background is long, differently coloured lamps may be provided at different parts. The background and panels may be rubber covered to allow of attachment of articles by pins. Fig. 2 shows one method of supporting the panels b, which are here suspended by rollers c<1> running on a top rail d, the bottom ends of the panels being guided by rollers f riding in a slot f<1>. Continuous or intermittent mechanical means may be provided for sliding the panels b. Fig. 4 shows an endless conveyer i carrying a spring-retracted projection i<1> which strikes a similar spring-retracted projection b<1> on the panel b, and carries the panel along until it is stopped by an abutment j. The projection i<1> then yields to slip by the projection b<1> and to strike a switch arm k which reverses the conveyer i. The panel is then pushed back by the projection i<1> until at the far end the projection b<1> yields and the conveyer is again reversed. In another form, the panels are carried on an inclined track and run back by gravity, the conveyer i then moving continuously in one direction. In a further arrangement the conveyer moves in an undulating path and releases the panel when the projection descends the undulations.

Title: Colour filter assembly device for use in colour-photographic projection printing
IPC: G03B27/73
Filed: 1964-04-17
Abstract: 1,009,346. Colour filters. DURST S. p. A. BOLZANO, FABBRICA MACCHINE ED APPARECCHI FOTOTECNICI. April 17,1964 [April 22, 1963], No. 16066/64. Heading G2A. A colour filter assembly comprises two guides, both mounted transversely with respect to a central aperture for the printing light, each guide carrying a pair of filters which can be movable separately into and out of the light path, the arrangement being such that only one filter of each pair can be in the light path at a given time, and such that each filter can be retracted only so far as to lie just outside the light path. The arrangement is described in connection with a projection printer. As shown, the first pair of filters are a yellow filter 3, fixed to a flide 7, and a magneta filter 4 fixed to a slide 8. The slides can move in a fixed vertical guide 1,1<SP>1</SP>. Slide 7 extends downwards within slide 8, and is held against the head 21 of a rod 11 by spring 9, the rod being fixed at its lower end. Slide 8 has a rack portion 12 which meshes with a pinion 13. When pinion 13 rotates anticlockwise, slide 8 moves upwards so that magneta filter 4 is gradually inserted into the central light beam aperture while yellow filter 3 is prevented from moving by the head 21. When pinion 13 rotates clockwise, filter 4 is gradually retracted again out of the light path into its original position. If the movement is continued, two stops 14 on slide 8 engage slide 7 and depress it against spring 9, so that yellow filter 3 is gradually moved into the light path. Thus only or other of filters 3, 4 can be interposed in the light path. A second pair of filters, yellow filter 6 cyan filter 5, are similarly mounted in a fixed horizontal guide 2, 2<SP>1</SP>. They are carried by slides 23, 22 respectively, which both have racked portions 16, 15, engaging with a wide gear wheel 19, The arrangement is such that either filter 5 or 6 can be moved into the light path. Since one pair of filters is yellow and magenta, and the other pair yellow and cyan, any two colours can be combined.

Title: Improvements in or relating to battery charging apparatus
IPC: H02J7/04
Filed: 1944-08-24
Abstract: 577,448. Charging batteries. PARTRIDGE, WILSON & CO., Ltd., and LOACH, F. A. Aug. 24, 1944, No. 16136. [Class 38 (iv)] The current controlling means for a static rectifier battery charging apparatus comprises, in combination, a contactor 3 which is arranged between the rectifier 2 and the A.C. source 1 and which is adapted for electro-magnetic operation to the " on " position from a normal " off " position, a relay 4, adapted to be electromagnetically opened from a normal closed position, and a condenser 5 in series with the coil 6 of the relay, the contacts 9, 10 of the relay being in series with the coil 11 of the contactor 3. With the circuit as shown, when a battery 14 is connected to the output terminals 15, 16, the coil 11 is energised from the battery to close the contactor 3. The rectified A.C. from the rectifier 2 charges the battery, but, because of the constant D.C. voltage from the battery, does not affect the coil 6. When, however, the battery is disconnected, the rectified intermittent A.C. energises coil 6 and opens contacts 9, 10, thereby de-energising coil 11 and opening contactor 3. When the rectifier output ceases, the coil 6 is de-energised and contacts 9, 10 reclose in readiness for the next charging operation.
