Abstract: 1536562 Laminates BICC Ltd 12 Feb 1976 [13 Feb 1975 14 Feb 1975] 6221/75 and 6365/75 Heading B5N A method of making a laminate comprises incorporating in a composition comprising an ethylene homopolymer, a copolymer derived from a mixture of monomers including at least 50 mol per cent ethylene and at least 75 mol per cent ethylene and propylene combined, or in a post-chlorinated derivative of such a polymer, (a) a free radical generator capable of generating a predetermined number of free radical sites in the polymer when decomposed by heating and, (b) a silane SiRY 2 R<SP>1</SP>, where R is a monovalent olefinically unsaturated hydrocarbon or hydrocarbonoxyl radical, Y a hydrolizable organic radical and R<SP>1</SP> is R, Y or a methyl group, in an amount sufficient to react with substantially all the free radical sites; heating the mixture to decompose at least a major proportion of the generator to form freeradical sites in the polymer and react predominantly by grafting with the silane without cross-linking, applying the composition in a heat-softened condition to paper or cloth and then subjecting it to the combined action of a silanol condensation catalyst and water to produce a cross-linked polymer. The comonomer may be vinyl acetate or ethylacrylate, the generator 1,3 - bis - (α - t - butylperoxyisopropyl)benzene or dicumyl peroxide, the silane vinyl trimethoxysilane and the catalyst dibutyl tin dilaurate or a titanium ester. The plastics layer may be applied as a preformed layer or by extrusion, optionally being sandwiched between two layers of paper or cloth.

Filed: 1954-03-03
Abstract: 777,575. Expansible containers. FELIX INDUSTRIES, Ltd., A. March 1, 1955 [March 3, 1954], No. 6292/54. Class 66. [Also in Groups XXI and XXIX] A container adapted to be dropped from an aircraft and used to carry.liquids, finely divided solids or small articles such as cartridges, has walls comprising layers 1-3 of flexible material pleated as in Fig. 3 by folding the material 27-29, 31 and securing the pleats by adhesive 30, the strength of the adhesion being less than the tensile strength of the material so that the adhesive bonds break on impact. The walls are bent over at each end of the container and secured by rings 6, 11, 19, 21 and bolts 12, 22 to sheets of glass cloth 7-10 and 20, the ends being closed by a metal plate 13 having an orifice 14 with a screw cap 18 and by a sponge rubber base 23 attached by a flexible band 25 to the body of the container. A lining 4, impermeable to the liquid contents, is pleated to remain in contact with the outer walls 1-3 as they expand on impact. An inner liner 5 is formed of flexible but inextensible material permeable to the liquid so that on impact the liner 5 absorbs some of the. energy of the liquid passing therethrough. The liner 5 and lining 4 may be omitted if the contents are solids. Fins or a drogue may be attached to stabilize flight.

Title: Improvements in and relating to electric measuring instruments
IPC: G01R17/16
Filed: 1939-02-25
Abstract: 525,690. Voltmeters; wheatstone bridges. WILKINS, S. R., and AUTOMATIC COIL WINDER & ELECTRICAL EQUIPMENT CO., Ltd. Feb. 25, 1939, No. 6300. [Class 37] An A.C. indicating instrument comprises a thermionic amplifier, the A.C. output of which is. taken to an indicating voltmeter and also to a subsidiary rectifier, the output of which is fed back to the amplifier to modify its amplification characteristics. The application to a thermionic balance indicator for A.C. bridge measurements is shown. The output from the bridge is fed through the condenser 10 and leak 11 to a first amplifier valve 12 and thence to; a second stage amplifier 13. the output from which is fed through one half of a double diode 14 to a voltmeter 16. The amplifier output is also connected to the anode 14<1> of the other half of the double diode through a condenser 17, the cathode 18 of this diode being positively biassed by connection to a tapping on a resistance 19 shunted across the supply. When the output voltage of the amplifier 12, 13 exceeds a certain value the bias voltage on the diode 14<1>, 18 is overcome, the diode rectifies, and a negative voltage appears at the diode load 20 and is applied, after filtering out A.C. components by filters 21, 22, to the grids of the amplifier valves 12, 13. These are of the variable-mu type and the amplification is progressively reduced with increase of the bridge voltage so that overloading is prevented when the bridge is unbalanced whilst preserving sensitivity at the balance point. The negative voltage across the load 20 may also be applied to the grid of the oscillator amplifier supplying the bridge so as to control the voltage applied to the bridge. The indicator amplifier and the double diode may be combined in one valve.

Abstract: 699,434. Centrifugal separators. BOLDRIN, L. March 13, 1952 [Feb. 20, 1952], No. 6526/52. Class 23 In a centrifugal separator for the purification of liquids and comprising a rotary 'drum 10 having an axial inlet 8, a peripheral chamber 13 for collection of solid particles, outlets 27 for the heavy liquid impurity and an axial outlet 9 for purified liquid, the flow through the axial outlet is controlled in accordance with the quantity of the heavy liquid impurity in the drum and with the speed of rotation of the drum. The liquid to be purified passes through ports 16 and between vanes 19 to the interior of. the drum, a baffle 18 deflecting the flow towards the peripheral chamber which is periodically emptied by removing plugs 21. The outlets for the heavy liquid impurity are controlled by valves 26 attached to pivoted members 25 having a density such that they move with the inner boundary of the heavy liquid impurity. The pivoted members are connected by linkages 28, 29, 30 to slide a sleeve 34 over the ports 35 to stop the flow of purified liquid through the axial outlet when the quantity of heavy liquid impurity in the drum is excessive. A spring pressed piston 36 slidable within the axial outlet is moved by a centrifugal governor 41 to open the ports 35 when the drum rotates at a given speed. In a modification, Fig. 5 (not shown), the valves 26 are dispensed with, and the heavy liquid impurity discharges through an annular outlet surrounding the axial outlet for purified liquid.

Abstract: 326,013. Addicks, A. March 1, 1929. Safety appliances.-A drop-down safety-guard 1 for the front of motor and like vehicles is automatically moved into its operative position by the inertia of an oscillatably mounted pendulum lever 6 either when the vehicle is braked to slow its forward movement, or when it is started or has its velocity increased in a rearward direction, the guard being automatically returned to its normal inoperative position when the vehicle is restarted or accelerated forwardly. In the arrangement shown in Fig. 1, weights 7 at each side of the vehicle are adjustably mounted on the rear arms 6 of double-armed levers, the forward arms 2 constituting the side members of the guard 1, and the whole device being pivoted at 3 on the supporting arms 4 of the bumper bars 5. Normally the guard 1 is horizontal, but it falls to a substantially vertical position when the vehicle is braked, stops being provided to limit its movement. Modifications are described in which the pendulum lever in its first movement releases a catch which holds the guard in an horizontal position, and in which the pendulum lever is connected to the guard 1 through a system of levers. In a further modification, Fig. 5, spherical weights 25 running in bent tubes 24 fitted with adjustable end stops 26 replace the weights 7 on the lever arms 6.
