Title: Improvements in or relating to drum brakes
IPC: F16D53/00
Filed: 1963-10-31
Abstract: 1,026,985. Drum brakes. H. TEVES, E. A. TEVES, and M. TAUSEND, [trading as ALFRED TEVES MASCHINENUND TURENFABRIK KOMM.-GES.]. Oct. 31, 1963 [Dec. 7, 1962], No. 43025/63. Heading F2E. In a combined internal and external shoe drum brake including a brake carrier 17 to which is attached a wheel brake cylinder 22 and a first brake shoe 3, the brake carrier 17 is slidable in a radial direction on a flange 18 of an axle tube 19, the second brake shoe 4 is guided in a gallery disposed on the brake carrier 17 and the brake shoe 4 operated by the piston of the wheel brake cylinder or by a cable system 41 acting through a lever 25 fulcrumed at 27 to apply the brake and the brake carrier is prevented from rotation in a circumferential direction by abutments formed by brackets provided on a flange 18 of the axle tube 19. The brake carrier 17 and the flange 18 on the axle tube 19 are interconnected by a slackadjusting device 20 which automatically compensates for lining wear. The adjusting device 20 consists of a pin 35 rigidly connected to the brake carrier 17 and housed in a sleeve 28 associated frictionally with the flange 18 a clearance X corresponding to the brake shoe clearance. Lining wear causes the brake carrier 17 to move the adjusting pin 35 towards the axis of the axle tube 19 and the slack-adjusting sleeve 28 is moved to approach one end of the slot 34 as the lining wear increases. A return spring 42 pulls the brake carrier 17 back by the amount X when the brake is released so that the spherical portion 36 of the pin 35 abuts the other side of the passage in the sleeve 28. Members 38 are disposed on torque taking brackets 37 formed on the flange 18 to reduce noise and wear (Fig. 2, not shown). The construction of the brake carrier is such that it acts as a brake back plate to protect the brake members from dirt and moisture. Springs 39 prevent rattle of the brake carrier 17 when guided on the flange 18.

Title: Separation of isobutene from other hydrocarbons
Inventor: CROCKER HENRY PETER
IPC: C07C7/171
Filed: 1959-12-19
Abstract: Isobutene is separated from a C4 hydrocarbon mixture by selective absorption in a mixture containing acetic acid and 0.5%-30% by weight of sulphuric acid, separating the non-absorbed hydrocarbons, recovering the isobutene by heating the acid phase to 50 DEG C.-120 DEG C. and recycling the acid to the absorption. Absorption may be effected at 5 DEG C.-85 DEG C. with the hydrocarbons in liquid or gaseous phase, e.g. passing the hydrocarbons countercurrent to the acid.  Cooling is necessary as an exothermic reaction occurs. Recovery of the isobutene may be effected in one stage but a purer product is obtained by first neutralising the sulphuric acid with an aqueous base, e.g. an alkali or alkaline earth metal hydroxide or acetate or with a cation exchange resin, before reducing the pressure if this is necessary, heating to 50 DEG C.-120 DEG C. to expel hydrocarbons other than isobutene, and filtering off the sulphate formed, then adding further sulphuric acid, heating to recover the isobutene and recycling the acid mixture.

Abstract: 1,149,134. Snap action switches. L. W. BURCH and H. K. BURCH. 22 Sept., 1967 [22 Sept., 1966], No. 43292/67. Heading H1N. A snap acting blade, Fig. 2, e.g. of phosphor bronze, comprises a central leg 20, tension legs 22, 24 and contact-carrying amplifier legs 46, 48. A bar 26 is connected under compression to points 22a, 24a of legs 22, 24 through adjustable rivets 28, 30 and applies tension to legs 22, 24 to force them apart and warp the blade to a first condition in which one amplifier leg, 46 say, extends in a plane above the plane of leg 20, and the other leg 48 extends in a plane below. When the blade is snapped, legs 46, 48 move to opposite planes. Bar 26 is carried by a shaft 38 rotatably mounted on a stationary insulating base 37 carrying contacts 56, 58 with raised portions 60, 62. Legs 48, 46 carry contacts 52, 50 co-operating therewith and connected to a terminal (70, Fig. 3, not shown) through the conducting blade, rivets, bar and shaft. When, during anticlockwise rotation of the blade by a knob (54), contact 52 is engaged with raised portion 60, leg 48 is snapped to the up position to break contacts 52, 56 and leg 46 is snapped downwardly to bring contact 50 into engagement with contact 58. The blade may be incorporated in a double-pole, double throw switch (Fig. 5). The blade, Fig. 8, has points, similar to 22a, 24a, mounted on stationary stressing posts 28a, 30a connected to a stationary base 77 with contacts 92, 90 to warp the blade. The shaft 120 is secured to an insulating member 80 provided with contacts 100, 102 co-operating with contacts 90, 92 and with contacts 107, 109 connected to contacts 100, 102 and co-operating with the blade contacts 104, 106. Member 80 has notches 84, 82 around posts 28a, 30a, the smaller notch 84 co-operating with post 28a to limit rotation of member 80. As member 80 is rotated, contacts 100, 102 continuously engage contacts 90, 92, but when one of the protuberances 108, 110 engages a contact 104, 106 in the lower position the latter is snapped to the raised position and a changeover is effected. Contacts 109, 107 are extended to the edge of notch 84 and current is supplied to the blade through post 28a so that on over-travel in both directions post 28a engages contact 109 or 107 to shunt the blade. A plurality of coaxial blades, and parts 80 and 77 may be operated by a single shaft (Fig. 9). In a modified blade (Fig. 10), the amplifier legs are connected on opposite sides of the centre of the central leg. The switch of Fig. 2 may be hermetically sealed in a copper casing (402, Figs. 11-13) and a soft iron bar (409) is secured to bar 26. The shaft 38 is rotated either by an electromagnet (410, Figs. 11, 12) outside the casing, a return spring 412 being provided, or by a rotary magnet (420, Fig. 13).

Abstract: 1278816 Controlled-release medicaments G S BANKER 2 Sept 1969 [3 Sept 1968] 43479/69 Heading A5B [Also in Division C3] Orally administrable sustained release compositions comprise a drug having an acid or basic functionality and a physiologically harmless carboxylic acid chemisorbed on the particles of a latex of a polymer containing acidic and/or basic groups the functionality of which is complementary to that of the drug and which is hydratable (at least to the extent that it swells) in the gastrointestinal tract. Suitable polymers are those formed by the emulsion polymerisation of such monomers as acrylic, methacrylic, crotonic, itaconic and maleic acids, half esters of maleic acid, maleic anhydride, sulphonated and phosphonated styrene, vinylamine and aminoalkyl esters of the above acids. Copolymerizates thereof, e.g. with vinyl compounds, acrylates, methacrylates and acrylonitrile may also be employed. The acid may be a mono- or polycarboxylic acid e.g. acetic acid, glycine, oxalic, malonic, succinic, glutaric, adipic, maleic, fumaric, citric or tartaric acid and numerous drugs and drug types are mentioned. The compositions may be made by adding solutions of the drug and acid to an emulsion (latex) of the resin. The product may be used as such in a liquid preparation or the resin may be separated e.g. by filtration, centrifugation, spray-drying &c either with or without initial flocculation as by addition of an electrolyte. Specific examples relate to preparations in which the drugs are methapyrilene, chlorpheniramine, phenylephrine, phenylpropanolamine, pyrilamine, atropine and oxytetracycline (all as salts) and phenobarbital, the resins being anionic acrylic copolymers and styrene-acrylic nonionic polymer. A different drug or some of the same drug may be present in the particles which is not chemisorbed but is merely physically entrapped.

Filed: 1960-12-19
Abstract: 945,316. Drying systems. FREEMAN, TAYLOR MACHINES Ltd. Dec. 18, 1961 [Dec. 19, 1960], No. 43643/60. Heading F4G. Hot and wet material e.g. yarn in hanks or other forms, woven and knitted fabrics subsequent to a dyeing or analogous wet treatment, or granular and powdered materials, are dried in a closed vessel wherein the pressure is suddenly, i.e. in less than one minute, reduced to below atmospheric to create a vacuum and causing liquid in the material to flash off as a vapour carrying or entraining droplets of liquid, and condensing the flashed-off vapour. The drying rate may be substantially controlled by regulating the rate at which the partial vacuum is created in the vessel e.g. a vacuum of 25 inches of mercury in under one minute, the first few inches being generated very suddenly. The vacuum may be created by admitting low pressure steam e.g. 5 p.s.i. to exclude or expel air in the vessel and then rapidly condensing it. Flashed-off vapour and any low pressure steam may be condensed by a refrigerant, cooling the outer surfaces of the vessel, cooling coils or sprays therein.

Abstract: 1,247,725. Treating garments. MANN MFG. Inc. 19 Sept., 1968 [22 Sept., 1967], No. 44647/68. Heading A3V. A method of increasing the wear resistance of a textile fabric 10 includes the steps of adhering a thermoplastic film 18 to one surface of the fabric by the application of heat and pressure, cooling the film and fabric and then baking them in an oven at 275‹F to 450‹F for 8 to 20 minutes. The thermoplastic film 18 is applied to the inner surface 20 of the fabric 10 which may be woven, knitted or otherwise formed as by crocheting, such as at the interior surface of the knees (28) Fig. 3 (not shown) of a pair of slacks (30), by heat and pressure. A suitable thermoplastic film is a vinyl chloride acrylate or a phenolic ethyl acrylate polymer. The film 18 is 2 or 3 mils thick and has a suitable release paper adhered to one surface. The film may be applied by utilizing a pair of heated porous platens (32) (34) Fig. 4 (not shown) which allow the escape of any gas evolved. The release paper is stripped off and the fabric cooled to room temperature by a stream of air or by a cryogenic or refrigerated plate. The garment may then be creased, a silicone solution being sprayed on the back of the film to prevent adherence of the film to itself. Alternatively, adherence can be prevented by leaving the release paper until the crease has been formed. After creasing the garment is fed through an oven. Quantitative method examples are given.
