Title: Improvements in or relating to circular knitting machines
IPC: D04B35/00
Filed: 1959-08-12
Abstract: 926,092. Knitting-machines. H. EPPINGER, and G. EPPINGER, [trading as GOTTLIEB EPPINGER KOMM.-GES.]. Aug. 31, 1959 [Nov. 26, 1958], No. 29585/59. Class 74 (2). A set of circular knitting-machines has the needle cylinder for each machine of the same diameter but the tricks of different depths so that the actual diameter of the needle circle for each machine varies from the others of the set of machines. Accordingly the width of the needle sliders or the length of their butts or of the needle butts in each cylinder differs from those in the other cylinders. Jacks may be positioned beneath the sliders or needles and be positioned at the same or a less depth than that of the needles or sliders. The tricks may be formed by milling the cylinders to the appropriate depths or by providing trick walls 21 held in place around the cylinder. To maintain the trick walls 21 at correct spacing the needle sliders may be slotted as at 23 through which slots supporting members 24 project to engage the opposite faces of two trick walls and being of slightly greater thickness than that of the sliders retain the walls at a distance to enable the sliders to move freely.

Title: Control valve
IPC: B60T8/26
Filed: 1966-07-01
Abstract: 1,085,188. Valves; fluid-pressure brakes. WAGNER ELECTRIC CORPORATION. July 1,1966 [Sept. 28,1965], No. 29646/66. Headings F2F and F2V. A valve for providing a differential braking effect between the front and rear wheels of a vehicle to prevent the latter from skidding comprises a port 26 connected to the master cylinder and the front brake cylinders, a port 27 connected to the rear brake cylinders, a differential piston 30 urged to the position shown by opposed springs 35, 44 and a ball valve 46 movable in an extension 37 of piston 30. The housing 20 is inclined when installed in a vehicle so that the ball is biased to the position shown. During initial depression of the brake pedal, the pressure in inlet port 26 rises and is communicated to port 27 through bore 38 in piston 30. The rising pressure moves piston 30 to the left to store energy in spring 44. At a predetermined deceleration, ball 46 rolls upwardly to seat against the inlet to bore 38, thereby disconnecting ports 26, 27. Up to this point, the front and rear brake operating pressures are equal but further depression of the brake pedal moves piston 30 to the right allowing spring 44 to progressively release its stored energy. The rear brake operating pressure thus increases non-linearly with respect to, and at a lower rate than the front brake operating pressure. When spring 44 reaches its fully relaxed state, further increase in the pressure at port 26 causes the pressure at port 27 to increase linearly in proportion to the areas A 1 , A 2  of piston 30. In the alternative embodiments of Figs. 4 and 5 (not shown), the ball valve works in a sleeve biased towards the piston by a light return spring and the energy storing spring (44) is located between the larger diameter part of the piston and a seat engageable with shoulder (23) and with the smaller diameter piston part.

Title: Process of hydrolyzing ethylene-sulfuric acid absorbate
IPC: C07C29/06
Filed: 1954-10-18
Abstract: Ethylene-sulphuric acid absorbate containing both mono- and di-ethyl sulphates is hydrolysed by a process comprising introducing the absorbate into the mid-section of a liquidvapour counter-current contacting device, introducing water into the mid-section of the device in sufficient quantity to dilute the sulphuric acid to 35-65 per cent by weight and heating the base of the device so as to maintain boiling in the base and vapours moving progressively upwards in equilibrium with liquid from the base to the top of the device; the amount of feed and the volume of the device being co-ordinated to give an average residence time sufficient to hydrolyse at least the major portion of the diethyl sulphate, the vapours being condensed adjacent to the upper end of the device, the condensate being returned in part as reflux, the amount returned being sufficient to hold the amount of alcohol conducted away at not more than 25 per cent of that produced by hydrolysis, and the amount of heat introduced into the base of the device being equivalent to that which would be introduced by from 1/2 to 4 mols. of steam, saturated at 20 p.s.i.g. per mol. of sulphate radical introduced, and conducting hydrolysate away from the base of the device.  In general, the temperature in the base of the counter-current contacting tower is in the range 225-300 DEG  F. and the pressure in the tower ranges from 0-100 lbs. gauge.  In an example ethylene-sulphuric acid absorbate is treated according to the process claimed to give overhead consisting mainly of ether with small amounts of ethanol, and material withdrawn from the base of the tower consisting substantially of ethanol.
Patent GB-661368-A (GB)
Title: Improvements in vinyltetrahydronaphthalenes and methods of preparing the same
IPC: C07C1/24
Filed: 1947-11-11
Abstract: A method of preparing a monovinyltetrahydronaphthalene which comprises causing the vapours of a tetrahydronaphthalene methyl carbinol to contact activated alumina thereby to dehydrate the tetrahydronaphthalene methyl carbinol to a monovinyltetrahydronaphthalene.  The activated alumina may be mixed with one or more metallic oxides chosen from the oxides of chromium, tungsten, molybdenum and man-ganese and the dehydration preferably takes place under reduced pressure, the carbinol being maintained in the vapour phase as long as it is in the presence of the catalyst or at such a temperature that polymerization of the vinyl tetrahydronaphthalene or an undesirable condensation of the carbinol might result, The starting materials may be prepared by reacting tetrahydronaphthalene with acetic acid or acetic anhydride or other acetylating agents in the presence of a Friedel-Crafts catalyst such as aluminium chloride or bromide, zinc chloride, boron fluoride and sulphuric acid.  The proportions of a - and b -monoacetyltetrahydronaphthalene produced may be varied by altering the temperature, solvent or catalyst concentration.  Increased temperature results in the production of increased quantities of polyketones.  The reaction is more easily controlled in the presence of an inert solvent such as carbon disulphide, nitrobenzene or carbon tetrachloride and in general the mixture of tetrahydronaphthalene and acetylating agent is added to the catalyst suspended or dissolved in the solvent at such a rate that the temperature remains in the range necessary for the production of the desired ketone.  At the completion of the reaction the mass is hydrolysed with water, the organic layer allowed to separate and the ketone, obtained by distillation, is reduced to the carbinol by hydrogenation in the presence of a catalyst such as finely-divided platinum, platinum oxide, palladium or copper chromate, and preferably a solvent such as methyl alcohol.  In examples: (I) b -vinyltetrahydronaphthalene and (II) a -vinyltetrahydronaphthalene are prepared by flashing the appropriate tetrahydronaphthalene methyl carbinol through a heated column under reduced pressure, packed with alumina pellets and immediately cooling the product.  Polymerization of the monovinyltetrahydronaphthalenes may be inhibited by the compounds that inhibit the polymerization of styrene, e.g. catechol and hydroquinone, and these may be washed out of the dissolved monomer with alkali prior to polymerization or polymerization may be carried out in the presence of a small amount of inhibitor at elevated temperature with or without a polymerization catalyst.  The Specification as open to inspection under Sect. 91 comprises also the use as acetylating agents of acetyl chloride or bromide or ketene in preparing the mono-acetyl tetrahydronaphthalenes. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in valve actuator assemblies for internal combustion engines
IPC: F01L3/10
Filed: 1955-10-20
Abstract: 785,662. Valve accessories. GENERAL MOTORS CORPORATION. Oct. 20, 1955 [Nov. 9, 1954], No. 30000/55. Class 135. An overhead poppet-valve for an internalcombustion engine operated by way of a tappet, push-rod and a rocker 3, Fig. 2, has a stem 7 around which is a U-section washer 11 forming a seat for one end of the valve spring 9 and having sufficient radial clearance 12 from the stem 7 to accommodate any lateral movement caused by the action of the rocker 3 and so prevent sticking of the stem during its axial motion. Seated on the washer 11 is a dished cap 16, which, when the valve is closed, has a small clearance 28 from the end face 17 of the stem 7. Removably located on the stem 7 is an abutment device comprising split wedges 18 and a tapered keeper 20, which secures the latter on the stem, this wedging engagement being assisted by tongues 21 on the wedges that are received in an annular groove 22 on the stem periphery; the lower end face 26 of the keeper 20 abuts the opposing surface 27 of the washer. In a modification, the abutment device consists of a C-shaped member sprung on to the stem groove, and the dished cap is replaced by a flat disc. In another modification the flat disc rests on a bush in the U-section washer, the other end of which bush abuts the inner part of the latter; the stem has the bottom of its groove relieved to enable the C-shaped member to be readily inserted and removed. In a final modification, the stem embodies a groove 322, Fig. 6, which serves to positively retain the keeper 120 against longitudinal movement; the valve clearance is provided between the cap 316 and the keeper 120, which clearance can be adjusted by screwing the cap more or less into the washer 311.

Title: A process for the treatment of copper-containing iron pyrites
IPC: C22B3/08
Filed: 1948-11-18
Abstract: Copper-containing iron pyrites is heated to below its sintering temperature, say at a maximum temperature of 900 DEG  C., to drive off one sulphur atom, and the porous product is treated with say 5 per cent sulphuric acid, for example at 90 DEG  C., metallic iron and sulphuric acid for reuse, being produced electrolytically from the ferrous sulphate produced, whilst the sludge, which contains substantially all the copper and any non-ferrous metals in the ore is treated, e.g. by melting and bessemer treatment, or by roasting and extraction, for the recovery of its constituents.  The hydrogen sulphide evolved in the acid treatment may be catalytically burnt to sulphur, but preferably a minor part is burnt to sulphur dioxide, using the electrolytically-produced oxygen, or air followed by purification, and the sulphur dioxide is reacted over an alumina-containing catalyst with the remaining hydrogen sulphide to produce sulphur in molten form.  Pressure may be used.  There may also be present sulphur dioxide produced by roasting the sludge with the electrolytically-produced oxygen.

Title: Improvements in semi-automatic weighing apparatus
IPC: G01G1/26
Filed: 1923-12-01
Abstract: 229,767. Avery, Ltd., W. & T., and Sykes, C. M. Dec. 1, 1923. Pendulum - weight apparatus; steelyard apparatus.-The invention relates to the type of apparatus described in Specification 176,650 in which the load is initially automatically balanced by a spring which determines the position of an indicator utilized in connection with the positioning of the poise weight of the steelyard, the steelyard balancing the major order of the load, while a pendulous resistant automatically balances the minor order. The pointer 43 for indicating the minor order of weighment is fixed to a lever 38 which is connected to a motiondamping device 42 and which co-operates with an overbalanced lever 32 connected to the steelyard 13 through a rod 30. The steelyard is fulcrummed in a swinging shackle 23 and carries a pendulum 26. The load is applied through a connecting-rod 5 which is suspended from a lever 8 supported at one end by the steelyard 13 through a rod 10 and at the other by a shackle 14 from a lever 15 which is connected to a coil spring 18, the upper end of which is adjustably secured to the scale housing on a bell-crank lever 19. The initial application of the load causes the steelyard arm to be raised till it comes into contact with the upper stop 50, while the spring 18 is extended, causing the pointer 20, secured to the lever 15, to move over the scale 21, giving an indication of the position to which the poiseweight 22 is to be moved. The major order of the load is then balanced, the steelyard arm 13 falling under the action of the weight 26 and allowing the overbalanced lever 32 to fall about its pivot 32<a>. An extension 36 of the lever 32 bears against a pin 37 carried by the bifurcated lever 38 which carries pendulum weights 40 and the pointer 43, so that when a position of equilibrium is reached the pointer 43 indicates the minor order of the load on the scale 44. The spring 18 may be replaced by a pendulum or other automatic weight-balancing resistant. Stops 52 on the scale housing take excessive strain in the case of fracture of the mechanism.
