Abstract: 1462790 Brake shoes; brakes SOC ANON FRANCAISE DU FERODO 9 Aug 1974 [10 Aug 1973] 35205/74 Heading F2E A brake comprises a cylindrical drum 10 to be braked by two brake shoes 12A, 12B which are respectively brought into contact with the inner and outer surfaces of the drum 10. Each shoe (e.g. 12A) comprises a friction lining 21A carried by a support plate 20A and the support plate 20A comprises a generally rectangular plane median portion 22 flanked laterally, on each side, by at least one oblique portion 23, 23<SP>1</SP>, the oblique portions 23, 23<SP>1</SP> of the support plate 20A forming, with the plane median portion 22 of the latter, dihedrons D, D<SP>1</SP> which are symmetrical two by two in relation to the median transverse plane P of the median plane portion 22, perpendicular to the latter, and the edges 24, 24<SP>1</SP> of which are parallel to one another. In the illustrated embodiment each support plate has only two oblique portions 23, 23<SP>1</SP> but these could be followed by other oblique portions. As illustrated and particularly described the two support plates 20A, 20B of the respective shoes 12A, 12B are identical. The friction lining 21A of shoe 12A is fixed (e.g. by adhesive bonding) on the convex face of the support plate 20A and the friction lining 21B of the shoe 12B is fixed to the concave face of the support plate 20B. The friction lining 21A has a minimum thickness E 1A  and a maximum thickness E 2A ; the friction lining 21B has a minimum thickness E 1B  and a maximum thickness E 2B . It is advantageous for the minimum thickness E 1A  of lining 21A to be equal to the minimum thickness E 1B  of friction lining 21B. The operating means of the brake comprise a piston 15 movable in a cylinder 16 and acting on the brake shoe 12A, and a transfer element 17 which transmits to the shoe 12B the force applied by the piston 15 against the brake shoe 12A when fluid pressure is delivered to cylinder 16. As shown the element 17 is C-shaped and incorporates the cylinder 16-the element 17 is movable relative to a fixed support 13.

Title: Photographic silver halide emulsions containing colour couplers and methods of processing them
IPC: G03C7/32
Filed: 1956-09-26
Abstract: a -a Bis-dodecyloxy-m-toluidine is prepared by adding m-nitrobenzaldehyde in dry toluene to lauryl alcohol in toluene in the presence of ptoluene sulphonic acid, and reducing the nitro group of the a -a -bis-dodecyloxy-3-nitrotoluene so formed.  The toluidine may be reacted with ethyl a -benzoyl acetate, ethyl-p-nitro-a -benzoyl acetate or ethyl a -acetyl acetate to yield respectively a -benzayl-3-[bis (dodecyloxy) methyl] acetanilide, a -(4-nitrobenzoyl)-3-[bis (dodecyloxy) methyl] acetanilide (which may be reduced to the corresponding a -(4-amino-benzoyl) compound) and a -acetyl-3-(bis (dodecyloxy) methyl] acetanilide.  1-Hydroxy-N-[3, 3-bis (acetyloxy) propyl]-2-naphthamide is prepared by saturating n-octyl alcohol with hydrogen chloride at 0 DEG  C. and adding acrolein to the ice-cold solution, shaking the 1, 1-bis-octyloxy-3-chloropropane so formed with liquid ammonia in a bomb and heating to give 3, 3-bis-actyloxy-propylamine, and reacting this with phenyl 1-hydroxy-2-naphthoate.  1-Carbethoxyoxy-2-naphthoic acid is prepared by adding ethyl chlorocarbonate to a mixture of 1-hydroxy-2-naphthoic acid and dimethylaniline in dioxane.  Treatment of the acid with thionyl chloride gives the corresponding acid chloride.  This acid chloride may then be reacted with a -a -bis-dodecyloxy-m-toluidine or a -a -bis-benzyloxy-m-toluidine in the presence of triethylamine to give respectively 3-[3-bis (dodecyloxy), methyl phenyl] naphth [2, 1-e]-m-oxazine-2, 4-dione and 3-[3-Bis (benzyloxy) methylphenyl] naphth (2, 1-e]-m-oxazine-2, 4- dione. Alkaline alcoholic hydrolysis of the former product gives 1-hydroxy-N-[3-bis (dodecyloxy) methylphenyl]-2-naphthamide. Specifications 524,154, 524,554, 524,555, 524, 557 and 541,589 are referred to.

Abstract: 360,697. Slicing-machines. NAAMLOOZE VENNOOTSCHAP TOT VERVAARDIGING VAN SNIJMACHINES, VOLGENS VAN BERKEL'S PATENT EN VAN ANDERE WERKTUIGEN and BERKEL, W. A. VAN, 33, Boezemsingel, Rotterdam, Holland. Nov. 28, 1930, No. 35817. [Class 28 (ii).] The discharge fly of a slice stacker is adapted to direct air upon the slices and thereby discharge them from the conveyer. When the pneumatic discharge is used, the fly is locked, by a bolt connecting it with a stationary part of the machine, in its vertical position, but when the bolt is removed the fly discharges the slices mechanically in the usual manner. As shown, the invention is applied to a stacker as described in Specification 353,442, the conveyer being a, rotary arcuate member 21, having prongs 25, driven by bevel gearing 13, 14 from the main shaft 4. The air blast is produced by a pump 55, the piston rod 57 of which has an end-pin 58 engaging with a slot 59 in the underside of the carriage 2. This effects a lost-motion drive to the pump, the plunger 56 of which carries a valve. The blast is produced towards the end of the return stroke of the carriage when the slice conveyer is correctly positioned for the discharge of the slice. The fingers 32 of the slice stacker are hollow and have slits, openings or nozzles 52 in their concave faces 32a, the size of the openings increasing progressively towards the top of the fly to equalize the blast effect. The hollow fingers 32 communicate with the pump through the trunnion 30 and a pipe 54, a cock being provided in the pipe for cutting-off the fly from the pump, when the mechanical discharge is used, the cock then also placing the pump in communication with the atmosphere.

Abstract: 1,032,018. Load-positioning devices. G. R. DIBB. Aug. 27, 1964 [Sept. 11, 1963], No. 35835/63. Headings B8H and B8J. [Also in Division G1] A load-positioning and controlling device is supported from a suspension eye 1 and carries a load indicated on a spring balance 2 (see Division G1) on a swivel hook 3. The hook is mounted on an inner sleeve 11 threaded into an outer sleeve 12, itself threaded into a trunnion 13 pivoted at 14 in a pair of plates 6 pivoted at 5 to the suspension eye 1. The lower end of the outer sleeve 12 is formed as a worm-wheel 15 housed in a gear-box 16 prevented from rotating by anti-torque links 17. The inner sleeve 11 is prevented from rotating by an anti-torque bar 18 extending through a slot 18a. Rotation of a worm engaging the worm-wheel 15 causes differential movement of the hook 3 with respect to the suspension eye 1. Coarse adjustment may be made by a handle 21 and fine adjustment upwards or downwards by one of two levers 20, each of which operates by means of a ratchet device to give precise steps of, say, 0À001 inch for each movement of the lever. The levers 20 may be operated from a distance by wires or rods.

The porosity may be produced by anodic treatment in concentrated hydrofluoric acid, and the porous layer may be doped to increase its conductivity. In a process for producing a high-power transistor, as shown, the porous layer 14, forming part of the collector region, is covered with a polycrystalline silicon layer 15 to protect the porous layer from oxidation during the processing steps necessary to form the emitter region 19 and the base region 17 in the silicon wafer 11. Alternatively, the porous layer may be formed after the transistor structure has been formed in the other surface of the wafer. In a further alternative process, an emitter region diffusion operation and a porous layer diffusion operation may be carried out simultaneously.

Abstract: Uranium values are extracted from oxidic material by leaching with a kerosene solution of a dialkyl phosphate to dissolve uranium oxides, scrubbing the leach liquor with an aqueous mineral acid solution, and thereafter extracting the dissolved uranium oxides from the scrubbed leach liquor with hydrochloric acid of about 12 M concentration.  The scrubbing acid, which may be sulphuric, hydrochloric or nitric acid is preferably of 0.5 molar strength; it serves to remove dissolved vanadium from the organic phase.  Suitable dialkyl phosphates are di - 2 - ethylhexyl -, di - iso - octyl -, and di-n-butyl acid phosphates.  The uranium can be recovered as U3O8 from the final hydrochloric acid solution by evaporation and calcining.
