Patent GB-610740-A (GB)
Title: Improvements in or relating to the production of light polarizing material
IPC: G02B5/30
Filed: 1946-04-01
Abstract: Light-polarizing sheets of a linear polyvinyl compound containing oriented molecules of "polyvinylene" are improved by treating them with a solution of boric acid or a derivative thereof capable of esterifying an alcohol, e.g. a halide.  By "polyvinyline" is meant the product obtained by dehydrating polyvinyl alcohol or its derivatives, e.g. incomplete acetals and ketals, according to Specification 548,759.  The sheet is soaked in an aqueous solution of the esterifying agent, which is preferably heated to 60-65 DEG  C., and allowed to shrink.  The sheet is then restretched while wet, either in the acid solution or in plain water, and finally dried, e.g. by baking at a temperature of 60-65 DEG  C.  Alternatively, the sheet may be held under tension while being treated with the acid solution.  The darkening effect produced by heating in air at high temperatures or in the absence of air at lower temperatures may be removed by incorporating into the sheet an alkaline compound.  The alkali, e.g. borax, is preferably added to the boric acid solution. The sheet, which may also contain a plasticiser such as glycerine, shows increased adhesion to adhesives such as incomplete polyvinyl acetals and may be laminated between glass or transparent resins.

[Also in Division G3] A copying control device for following external or internal contours comprises a biasing device 53 acting on a feeler 21 to bias it in the plane of the template, and azimuth control means for varying the direction of the biasing force in the plane, the control means comprising a bias servomotor 65 and a bias servo pickup 60 connected to the feeler to be actuated automatically by movements of the feeler in the plane. In a milling machine, a table supporting the work and the template is moved by longitudinal and cross feed motors. The control device is bolted on the machine frame and comprises a mounting plate 10 having a stylus support 13 and an azimuth turntable platform 12. The stylus 21 carries a template-engaging roller of the same diameter as the tool and is mounted by a ball 22 in the platform 13. Movements of the stylus are limited by a ball-bearing 26 having a tapered bore which can be moved axially of a tapered portion 27 of the stylus by rotation of a screwed sleeve 24, thus controlling the maximum feed rate of the work table. The stylus also carries a double-armed bracket 28, 29, the arms being connected by rods 32, 33, levers 40 and links 41 to reversing valves 36, 37, the valves and arms being urged downwardly and upwardly respectively by springs 38, 39, 42, 43. A link 50 also mounted on the stylus is connected to the bell-crank 53 pivoted to a bracket 46 on a turntable 45. The bell-crank is further connected by a link 55 to a lever 56 engaging the bias servo valve 60. A spring 61 acts on the lever 56 and tends to swing the stylus radially outwards in a direction determined by the position of the turntable 45. The turntable carries a gear 62 engaged by a gear 63 rotatable by a hand wheel 20 or the hydraulic motor 65 controlled by the bias control valve 60. A handle 72 controls supply of pressure-fluid to the valves. A handle 73 reverses the direction of operation of the motor 65 to provide for clockwise or anti-clockwise rotation of the turntable 45. Means for adjusting the length of the link 50 may be controlled by adjustments of the sleeve 24. The hydraulic means may be replaced by electrical means. The tool or work may move and means may be provided for varying the scale of reproduction. Reference has been directed by the Comptroller to Specification 853,797.

Abstract: 1,104,492. Systems including two supply sources. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 18 Jan., 1967 [10 March, 1966], No. 10619/66. Heading H2H. A system comprising two electrical equipments E1, E2 which may be first choice and standby equipments in a telephone system is provided with a selector switch S and relays A, B whereby either equipment may be selected as the first choice, the other becoming the standby equipment which takes over automatically on failure of the first choice equipment. When the positive supply voltages are connected to both equipments E1, E2 both relays A, B will tend to operate, the operative relay however being selected by the switch S. Should the equipment E1 be the desired first choice, switch AA in the selector switch is operated which places a short circuit on relay coil wB thus preventing the relay B from operating. Relay A thus operates, closing contact a1 to place a self maintaining short circuit on coil wB and closing contact a2 to complete the circuit for the selection of equipment E1. Should a failure occur in the supply to equipment E1, relay coil wA becomes de-energized thus removing the self maintaining short circuit on coil wB whereupon relay B operates and the equipment E2 brought in as standby. Selection of equipment E2 as first choice may be made by operation of switch BB in the selector switch in which case equipment E1 automatically takes over on failure of the supply to equipment E2. The relays A, B may be of the read type.

Abstract: 1287183 Photographic process for producing two images INTERNATIONAL BUSINESS MACHINES CORP 6 March 1970 [13 March 1969 (2)] 10753/70 Heading G2C A method of producing two separate images comprises providing a first light-sensitive coating on an area of a support, imagewise exposing and developing the latent image produced on exposure, providing a second light-sensitive coating on a different area of the support so that it does not overlap the image and imagewise exposing and developing to produce a second image. Preferably the light-sensitive coating is a diazotype material and the first image is produced by imagewise exposing a uniformly coated support so that an image is only produced on an area of the coating. The second image is produced by transferring a diazotype material on a temporary support under heat and pressure to an area of the support not containing the first image. Preferably this transfer material is an unsubbed polymerine film which acts as temporary support coated with a diazotype layer preferably containing a binder such as an acrylic or vinyl polymer or a cellulose ester, 2 diazonium compounds, 3 couplers and 1 toluene sulphonic acid and overcoated with a layer preferably containing polyvinyl acetate or polyvinylidene chloride and an arylsulphonamide  formaldehyde. The overcoated and light-sensitive layers are scored so that only small areas of these layers are transferred to the support containing the first image. The process is generally used for microfide work. The diazotype material may be developed by using ammonia under pressure. A vesicular material may also be used in the process.
