Title: Float method of manufacturing glass
IPC: C03B18/06
Filed: 1966-06-24
Abstract: <PICT:1085010/C1/1> In the manufacture of sheet glass by the "float" process, the ribbon is stretched laterally between the inlet and the exit of the float tank so that its width is increased and its thickness reduced. In the preferred embodiment molten glass is poured on to a bath of molten tin and is allowed to flow and attain its equilibrium thickness.  The ribbon thus formed is then subjected to the action of two opposed banks 24 of rollers 25. The rollers in each bank are driven at the same speed and are angled so as to stretch the ribbon laterally without accelerating its forward flow.  A second pair of roller banks is situated near the exit of the tank.  These rollers are driven at a higher speed than the first set and they serve both to stretch the ribbon longitudinally between the two roller banks and to subject it to a second transverse stretching. After leaving the second bank the ribbon passes beneath a cooler 30, whereby its temperature is so reduced that its dimensions are stabilized and thence into an annealing lehr.  In alternative embodiments, the ribbon is solely subjected to lateral stretching, or is laterally stretched once only, is longitudinally stretched by rollers in the lehr or is first longitudinally stretched and then laterally stretched.  Reference has been directed by the Comptroller to Specification 1,006,733.

Abstract: 805,716. Shovelling machines. BROWN INDUSTRIES, Ltd., D. Sept. 16, 195 [Sept. 15, 1956], No. 28283/56. Class 68(1) A tractor mounted loading device characterized by the provision of a mechanical linkage which causes the bucket to be swung forward relative to the lifting arms at the same time as the' bucket is raised by the lifting arms. In Fig. 1 which shows an over-loader two arms a are pivoted at b to a frame c fastened to a tractor. Hydraulic rams d act to rotate the arms about the pivots b. At the forward ends of the arms a are pivoted arms h fixed to a bucket i. Near the middle of the arms a are pivoted links m the upper ends of which are connected to the fixed brackets o by the links k pivoted at n and p and the lower ends of which are connected to arms h by the hydraulic rams j pivoted at s and r. Upward movement of the arms a initially produces forward movement of the arms h relative to the arms a and subsequently backward movement to avoid spilling the load as the arms a pass through the vertical position. The bucket is tipped by actuating the rams j. In a modification, to provide a front end loader, the arms h are omitted and the arms a extended and pivoted directly to the bucket. The hydraulic rams j are also pivoted directly to the bucket at their forward ends and are constructed to contract in length to tip the bucket. Alternatively the rams j may be replaced by links of fixed length and a latch mechanism provided.

Title: Improvements in or relating to hydraulic valve units
Inventor: ORLOFF GEORGE
IPC: E21D15/51
Filed: 1953-10-15
Abstract: 769,310. Valves controlled by auxiliary valves. BRITISH MESSIER, Ltd. Oct. 4, 1954 [Oct. 15, 1953], No. 28531/53. Class 135. In an hydraulic valve unit of the kind in which a main valve 11 resiliently biased towards a seating 15 is operated by a piston 34 under the control of a pilot valve 20, and in which the piston works in a cylinder 12 one end of which is connected to the main inlet passage 16 and the other end of which is connected by a by-pass passage 19, 21 containing the pilot valve 20 to the main outlet 22, a spring-loaded bleed control member movable relative to the piston in response to the pressure difference across the piston, is provided for varying the effective area of a bleed passage between the two sides of the piston so that the rate of travel of the main valve is controlled in a predetermined manner. In Fig. 1, the piston 34 and the main valve 11 are mechanically coupled for limited lost-motion, the valve head 13 being urged by a spring 31 against the seating 15, and the piston 34 by a spring 33 against a shoulder 35. The spring 33 also abuts against a fixed plug 32. The valve head 13 is carried on a stem 38 guided in a bore in the piston and carrying a ball-shaped poppet 39 forming the bleed control member. The poppet 39 after initial movement of the piston 34 sits in a hemispherical countersunk mouth 44 in the piston and cuts off the flow through the bleed passage constituted by ducts 41, 42, 43 so that the main valve is entrained by the piston 34. Subsequently the delivery pressure causes the main valve to move towards the plug 32 and the annular passage between the poppet 39 and the mouth 44 re-opens. The available flow area through this annular passage thus depends upon the pressure difference across the piston 34. In a further modification, the piston is integral with the head of the main valve and has a bore containing a shuttle member an orifice in which co-operates with a needle valve rigid with the piston. The shuttle member is normally pressed away from the needle valve by a spring.

Title: Stabilisers for synthetic rubber
Inventor: BROWN JOSEPH PATRICK
IPC: C08K5/38
Filed: 1962-07-26
Abstract: An aliphatic oxythiocarbonyl aromatic disulphide of general formula <FORM:0982857/C2/1> where R is an aliphatic group and Ar is an aromatic group, which is used for stabilizing rubber (see Division C3), is obtained by reacting a xanthate with an aromatic sulphenyl halide. The xanthate is usually a compound having the formula <FORM:0982857/C2/2> where R is the same as the aliphatic group in the product and M represents an appropriate cation.  The aromatic sulphenyl halide, usually a chloride or bromide, is such as to provide the aromatic group in the product that is linked through the disulphide system to the aliphatic-oxythiocarbonyl group.  Specified aliphatic groups are alkyl groups, cycloalkyl groups, or one of these groups having an aromatic substituent. The aromatic group (Ar) may be phenyl tolyl, naphthyl or diphenylyl or one of these groups having a substituent which may be chlorine, bromine, hydroxyl, alkoxy, nitro or an amino group.  The process is normally carried out by mixing equimolar quantities of the reactants in the presence of a diluent at a temperature not exceeding 50 DEG  C.  In the preferred method, an aqueous solution of the xanthate is shaken with a solution of the aromatic sulphenyl halide in a water-immiscible organic solvent, e.g. ether, petroleum ether or carbon tetrachloride, and the product isolated from the organic solvent.ALSO:A synthetic rubber contains as stabilizer an aliphatic-oxythio carbonyl aromatic disulphide having the formula. <FORM:0982857/C3/1> where R is an aliphatic group and Ar is an aromatic group. Specified aliphatic groups are alkyl groups, e.g. methyl, ethyl, n-butyl or t-butyl, cycloallyl groups such as cyclohexyl or one of these groups having an aromatic substituent. The aromatic group may be phenyl, tolyl, naphthyl or diphenylyl or one of these groups having a substituent such as chlorine, bromine, hydroxyl, alkoxy, nitro or an amino group.  The stabilizer is usually employed in an amount between 0.5 to 2 parts by weight. Synthetic rubbers mentioned are homopolymers of 1,3-butadiene or isoprene, copolymers of 1,3-butadiene with styrene, acrylonitrile, isobutylene or methyl methacrylate and ethylenepropylene copolymers.

Abstract: 655,823. Automatic control systems for gyroscopes. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AERONAUTIQUES. Nov. 10, 1948, No. 29256. Convention date, Dec. 23, 1947. [Class 38 (iv)] [Also in Group XX] A gyrovertical 1, Fig. 1, has pendulums 7, 11 mounted about the pitch and roll axes which control, by means of potentiometers 9, 13, the application of erecting torques by the torque motors 10, 14, respectively. The roll pendulum 11 carries a mass 16 capable of sliding against the action of a spring 17 and bearing a contact 18 for a potentiometer 19. The potentiometer is provided with a further contact 18a, Fig. 2, whose position is adjusted so that with gravity alone acting on the mass 16 no potential difference exists across 18, 18a. In the presence of centrifugal acceleration, mass 16 moves against the action of the spring 17 and the resulting voltage across 18, 18a is amplified by amplifier 20 and applied to a torque motor 15 which rotates shaft 3a and hence the pendulum 11 into the position it would occupy under the influence of gravity alone. A further pendulum 22 having brushes 23 movable over conducting segments 21 determines the sense in which the voltage is applied to the amplifier 20 in order to energize the torque motor 15 in the appropriate direction to restore the pendulum 11 to the true vertical.
