Title: Method of bending glass sheets
IPC: C03B23/025
Filed: 1966-09-01
Abstract: 1,135,467. Bending glass sheets. LIBBEY. OWENS-FORD GLASS CO. 1 Sept., 1966 [14 Feb., 1966], No. 38982/66. Heading C1M. In a method for bending glass sheets to relatively sharp angles the sheet 10 is supported horizontally on a bending mould 18, grooves 13 having been formed in the surface of the sheet to be bent, along the line of the intended bend with the groove terminating adjacent to but inwardly of the opposite edges of the sheet and the mould in the open position, is moved through the furnace 17 where heating devices 36 progressively heat the sheet to the correct bending temperature. The glass along the area of the groove is heated to a relatively higher temperature than the rest of the sheet by means of gas burners 37. The burners also serve to fire polish the side walls of the groove. The mould moves to the closed position (shown by the broken line) when the glass becomes softened along the line of the groove, and the glass bends along the line of the groove to a sharp angle with the wing sections 12 lying in angularly disposed planes relative to the centre portion. Specification 1,040,960 is referred to under Section 9 of the Patent Acts.

Title: Armour
IPC: F41H5/04
Filed: 1971-08-19
Abstract: 1392045 Composite glass material UNITED KINGDOM ATOMIC ENERGY AUTHORITY 18 Aug 1972 [19 Aug 1971] 39075/71 Heading C1M An armour comprises a composite material consisting of a mixture of a hard particulate and a fibrous reinforcing material dispersed throughout a matrix material, the distribution of the particulate and fibrous materials throughout the matrix material being such that there is a progressive change from a preponderance of particulate material on the matrix at one surface to a preponderance of fibrous material in the matrix at an opposite surface. The fibrous and matrix materials should be chosen so that the thermal coefficients of expansion are as nearly as possible the same; the same criteria desirably also applying to the particulate material. The matrix material may be a glass, e.g. nucleated glass; a borosilicate glass or a low-melting point soldering glass. The particulate material is suitably a ceramic material, e.g. silicon carbide, silicon nitride or boron carbide and the fibrous material is suitably a ceramic material, e.g. silicon carbide, silicon nitride a boron carbide in whisker form, a metal oxide refractory material, e.g. alumina or magnesia, carbon fibre or metal wire. The armour may be made by stacking together a plurality of sheets having differing proportions of particulate and fibrous materials dispersed in the matrix material in such a manner that the relative proportions of particulate and fibrous materials vary throughout the stack and hot-pressing the assembly, the sheets having a high particle density being formed by mixing just sufficient glass powder with a binder and particles having a range of discrete dimensions such that the smaller particles fit into the voids between the larger ones to form a slurry which is fed under a ductor blade on to a moving carrier to form a sheet, either the carrier or the sheet being mechanically agitated in the region of deposition to attain the desired packing of the particles. The agitation may be effected either by positioning an ultrasonic transducer within a trough through which the slurry flows or by supporting the deposition region of the carrier upon a vibrating plate or table. The hardness of subsequent sheets is reduced by decreasing the proportion of particles and increasing the proportion of fibres, the fibres being separate and stirred into the slurry or in the form of a tow passed through the slurry and under the ductor blade. An alternative sheet-forming method comprises passing a tow of carbon fibres through a series of spreading rollers to spread the fibres into a tape, impregnating the tape by passing it through a slurry of the ceramic and glass particles, optionally spraying further slurry on to both sides of the tape, removing excess slurry by further rollers and drying. In the armour, the properties may be made directional by relative alignment of the fibres of the sheets.

Title: Electrical operating circuits for windscreen wipers
Inventor: ADAMS DEREK STANLEY
IPC: B60S1/08
Filed: 1963-10-04
Abstract: 1,085,797. Control of motors. JOSEPH LUCAS (INDUSTRIES) Ltd. Oct. 5, 1964 [Oct. 4, 1963; Jan. 7, 1964], Nos. 39134/63 and 662/64. Addition to 1,051,067. Heading H2J. [Also in Division H3] The delay arrangements in the windscreen wiper motor control system described in the parent Specification is modified in various details. The wiper makes a single sweep and remains in its parked position until thyristor 21 is triggered; as shown, this occurs when transistor 24 conducts, which is when capacitor 28 has sufficiently discharged through 23 and 27. This is said to obviate accidental switching by transients. The circuit may be modified by omitting resistor 23 and replacing diode 22 by a large variable resistor. 28 is then charged through the anode and gate of 21 and transistor 24. When the wiper is switched off (switch 16 to 20) a discharge path for 28 is provided through 29 and the motor windings so that, upon switching on, the motor starts immediately. Alternatively, an additional diode and switch may be arranged to discharge the capacitor. In an alternative embodiment (Fig. 3, not shown) the thyristor is triggered when a unijunction transistor or a four-layer diode conducts, the delay in this case being effected by the charging of a capacitor via a variable resistor.

Abstract: 1386683 Dual-layer magnetic recording tapes MINNESOTA MINING & MFG CO 25 Aug 1972 [26 Aug 1971] 39815/72 Heading B2E A magnetic recording tape comprises a non- magnetisable backing member carrying a duallayer magnetisable coating up to 15Á thick, each layer being a homogeneous mixture comprising by weight a major proportion of magnetically anisotropic magnetisable particles and a minor proportion of a non-magnetic binder, wherein the magnetisable particles of the inner magnetisable layer are oriented so that their magnetically anisotropic axes extend predominantly in the longitudinal direction of the tape, and the magnetisable particles of the outer magnetisable layer are oriented so that their magnetically anisotropic axes extend predominantly in the crosswise direction of the tape. Preferably the coercivity of the outer layer is greater than that of the inner layer and ranges of coercivity and thickness are specified for each layer. Preferably the outer layer magnetic particles are of cobalt oxide modified acicular γ-Fe 2 O 3 , and the inner layer particles are of unmodified acicular γ-Fe 2 O 3 . Alternatively, the particles of at least one layer may be chromium dioxide. A coating between the magnetisable layers may be applied to increase adhesion. To provide good winding characteristics, the side of the backing member opposite the magnetisable layers may be coated with a dispersion of carbon black in a binder similar to that used in the magnetisable layers. A further magnetisable coating, e.g. of chromium dioxide particles, may be coated onto the outer magnetisable layer by vacuum depositions or electroless plating. To form the dual-layer tape the backing member, which may be stretched polyethylene terephthalate, is coated with a dispersion of magnetisable particles in a binder solution by gravure roll, the binder is cured to become solvent resistant, then the outer coat of a dispersion of magnetisable in a binder solution is coated on the cured inner layer by gravure roll and dried. In an example, the inner coating is formed by successively adding amounts of polyurethane elastomer solution, phenoxy resin solutions, acicular γ-Fe 2 O 3  particles, lecithin surfactant, Al 2 O 3 , conductive carbon black, and a silicone polymer to a ball mill, and the outer coating is similarly formed with amounts of polyurethane elastomer solution, lecithin, phenoxy resin solution, Al 2 O 3 , silicone polymer, and cobalt oxide modified acicular γ-Fe 2 O 3 .
