The tube is then heated in a furnace to melt the brazing alloy which brazes the fin to the tube and if the fin is of steel-clad copper seals the edge of the fin as in Fig. 6. The tube may have longitudinal fins instead of a spiral fin.
Patent GB-737999-A (GB)
Title: Improved particulate detergent compositions
Filed: 1952-03-11
Abstract: A solid, particulate detergent composition contains (1) 10-95 per cent by weight of sodium monoalkyl benzene monosulphonate having 9-18 carbon atoms in the alkyl chain, and (2) 1-10 per cent by weight of a sodium salt of an alkyl sulphuric acid having 2-6 carbon atoms, the remainder of the composition, if any, being essentially inorganic sodium salt builders.  The composition is produced by drying an aqueous slurry of an intimate mixture of the components.  In an example, 271 parts by weight of a mixture of C12-C15 polypropylene benzene sulphonic acids, containing about 10 per cent unreacted sulphuric acid, are added to a mixture of 94 parts of sodium hydroxide, 4.9 parts of sodium isopropyl sulphate and 430 parts of water.  The neutral slurry thus formed is thoroughly mixed with 178 parts of sodium sulphate and 130 parts of water and the mixture is dried to about 1 per cent water content on a drum drier to give a free-flowing powder. In other examples powdered detergent compositions are similarly prepared, using sodium n-hexyl sulphate, and sodium n-butyl sulphate respectively instead of sodium isopropyl sulphate.  The compositions may also be prepared by adding the appropriate alcohol to the sulphonation mixture after the sulphonation of the alkyl benzene, sulphation of the alcohol then occurring. Alternatively, sodium alkyl sulphates may be added to the neutralized aqueous slurry of alkaryl sulphonate and inorganic sulphate and the mixture agitated sufficiently to ensure uniformity of composition of the particulate final product.  The presence of the alkyl sulphates in the compositions reduces the tendency of the latter to cake on storage.

Filed: 1931-06-23
Abstract: 381,190. Electrolytic cells. POTTS, H. E., 12, Church Street, Liverpool.- (Hooker Electrochemical Co. ; 60, East 42nd Street, New York, U.S.A.) June 23, 1931, No. 6407/32. Divided on 381,183. Drawings to Specification. [Class 41.] A cathode-diaphragm structure of the kind employed in cells for the production of alkali from brine is made by bringing a suspension of fibrous material such as asbestos into contact with the active surface of a perforated cathode and forcing the liquid through the perforations by differential pressure. The fibrous material may be kept in suspension by submerged jets of liquid so balanced as to give a uniform coating. The suspension medium may be a liquid having a substantially greater specific gravity and viscosity than water in which case no agitation is necessary. A saturated solution of sodium chloride containing a small amount of sodium hydroxide and having a specific gravity of 1.2 is suitable. The cathode material may be stamped and perforated metal or may be woven of double crimped steel wire. The cathode may consist of a closed hollow member; fibrous material is deposited on the outside by immersion of the cathode in the suspension with the inner space connected to a vacuum. By the above method a diaphragm free from joints or seams may be deposited on a cathode having an irregular or warped surface such as the cathode assembly described in Specification 381,183.

Abstract: 512,667. Automatic control systems. SIEMENS & HALSKE AKT.-GES. March 1, 1938, No. 6471. Convention date, March 1, 1937. [Class 38 (iv)] [Also in Group XXXVIII] Tension.-To maintain a desired tension in winding material on to a reel 4 driven by a variable speed electric motor 6, pressuregauges 8, 8<1>, preferably operating by magnetostriction as in Specification 410,629, [Group XXXVI], are fitted to the reel bearings so that resistance in one arm of a bridge circuit is varied by the bearing pressure. Unbalanced potentials across the bridge are amplified for example by thermionic valves or bolometric amplifiers 12, and fed to the grid of a rectifier 14 in the motor circuit. One resistance 15 in the bridge may be normally adjustable to determine the tension. In a modification the effect of voltage changes in the a.c. supply to the bridge circuit is avoided by feeding the rectified bridge output into a resistance 26 and supplying a rectified current from the mains into a potentiometer 29. The potentials in these are opposed in the circuit of a coil 18 controlling the fluid-pressure operated regulator in the field circuit of a Ward Leonard generator supplying the reel motor 7.

Title: Improvements in machines for applying washers, rivets, eyelets and the like
IPC: A43D100/02
Filed: 1940-04-12
Abstract: 535,516. Delivering eyelets, washers &c. from hoppers. LEYLAND & BIRMINGHAM RUBBER CO., Ltd., HEYWOOD, F., SUMNER, J., and ECCLES, J. I. April 12, 1940, No. 6604. [Class 78 (i)] Washers, eyelets, rivets and the like are fed from a hopper to a shoot, the open end of which moves in a rectangular or 'elliptical path intercepted by the member with which the article is to be incorporated, so that the washer &c. is left behind as the shoot is retracted. Fig. 1 shows the invention applied to the supplying of dished eyelets to rivet pins 27. The eyelets fall by gravity from a shoot 2 into a double truncated conical container 4. A rotating wheel 7 carries peripheral pockets in which the eyelets fall by gravity, those with their dished sides facing in the wrong direction being prevented from entering by flanges on the wheel. On registering with the upper end of the shoot 25, they fall from the pockets thereinto, and are delivered in succession at the open end 23. The shoot 25 is carried by a reciprocating guide which is moved by the cord 11 and bell-crank 14 in one direction and by the counterweight 30 in the other. At the same time the shoot is pivoted at 22 and has a pin-and-slot connection 20 with the bell-crank 14 so that its free end 23 rises as it moves to the left and falls again on the return stroke. This enables the issuing eyelets at the end 23 to be placed over the rivet pin 27 and left there. Blades on the wheel 7 stir up the articles in the drum 4, and a driven star-wheel 17 enters the pockets to forcibly dislodge any eyelet remaining stuck therein.

Title: Improvements in liquid supply systems
IPC: E03B7/08
Filed: 1922-03-07
Abstract: 176,783. Finley, C. H. March 7, 1921, [Convention date]. Dispensing liquids.-A pump is arranged to draw liquids from different sources and supply the same to corresponding separate faucets, which, when opened, automatically cause the pump to actuate controlling mechanism which establishes connection between the supply-pipe and faucet for the particular liquid desired. The controlling- mecha.nism comprises a valve casing 10 containing a balanced valve 11 having three piston portions 12, 13, 14 connected by reduced portions 15, 16, and the valve casing is connected to supplies of different kinds of liquid, for example, a soft-water supply by means of a pipe 18 and a hard-water supply by means of a pipe 19, also to corresponding faucets 21, 20 by pipes 23, 22. Also connected to the casing 10 by means of inlet and outlet pipes 24, 26 respectively is a pump 25, the positions of these several connections to the casing 10 relative to the valve 11 being as shown. Assuming that the faucets 20, 21 are closed and that hard water is required, the faucet 20 is opened and the pump started, which pumps hard water from its source by means of the pipes 19, 24 and delivers it to the faucet 20 through the pipes 26, 22. If soft water is then required, the faucet 20 is closed and the faucet 21 opened. The hard water from the pipe 26 then passes to the top of the valve 11 by means of a pipe 27 leading from the hard-water outlet pipe to an opening in a. plug 28 at the end of the casing 10 and exerts a pressure upon the valve, causing it to move downwards, thus closing the pipes 19, 22 and opening the pipes 18, 23 to allow soft water to pass from pipe 18 to the faucet 21. In a similar manner when the faucet 21 is closed and the faucet 20 again opened, the valve is operated in an upward direction by the soft water through the medium of a pipe 29 which is led from the pipe 23 to the bottom end of the casing 10, allowing a supply of hard water to be obtained through the faucet 20. The system may be used for other liquids, such as kerosene and gasolene.

Filed: 1975-02-17
Abstract: 1466643 Locking nuts and bolts TRW Inc 17 Feb 1975 6654/75 Heading F2H [Also in Division H2] Connector parts 12, 14 are coupled together by a nut 66 which is rotated by a drive ring 90 carrying shoes 98 and wedges 110 acting on the ring, the wedges resisting rotation of the nut in the direction for uncoupling and the shoes abutting the wedges to render them ineffectual when the ring is rotated in the uncoupling direction. The part 12 comprises a mountable shell 16 with screw threads 32 and a keyway 30, while the part 14 comprises a shell 34, cable clamp 52, key 56 and carries the nut 66 and ring 90 between a flange 58 and a split ring 64. The ring 90 is rotatably mounted on the nut 66 and a flange 96 supports, and carries with it on rotation of the ring, the shoes 98 and wedges 110. The ring 90 includes angularly spaced recesses 72 each comprising shoulders 82, 86, 88 and a cam surface (84); within each cavity are a shoe 98 and a wedge 110 carried by the drive ring 90 and resiliently bearing against the shoulders 88, 82 by springs 108, 118 or rubber pads (118a). In use, rotation of the drive ring 90 (clockwise, Fig. 2) causes the shoes 98 to act against shoulders 100 tightening the nut 66 on the threads 32 and drawing the key 56 along the keyway 30 and the plug 14 into the socket 12. Any tendancy for the nut to work loose is prevented by a wedging effect as the cam surfaces (84) engage a complementary surface 112 on the wedges when the nut starts to move counterclockwise. Intentional uncoupling is effected by turning the drive ring counterclockwise causing the shoes to move against the springs 108 and their notched ends 106 to engage notched ends 114 of the wedges and separate the camming surfaces, torque being transmitted to the nut by the wedges and shoes.
