Title: Apparatus for holding fin members during bonding
IPC: B21C37/22
Filed: 1963-08-27
Abstract: 992,367. Making finned rubber; soldering. BROWN FINTUBE CO. Aug. 27, 1963 [Sept. 19, 1962], No. 33855/63. Headings B3A and B3R. Apparatus for holding fin members to be soldered or brazed to a tube comprises a plurality of fingers each having a bearing portion extending towards the work axis of the apparatus and being movably supported by a frame in spaced radial relation around the work axis so that the bearing portions define a circular periphery about the axis, resilient means urging the bearing portions towards the axis and means for simultaneously engaging the fingers and operating to move them to cause their bearing portions to move away from the axis. A frame 20 comprising two horizontal beams 23 supports spaced sets 21 of fingers 22, each set comprising a support plate 27 which engages grooved side frame members 25 and the beams 23 and which has a central opening 28 around which on one side of the plate are fixed a number of slotted support members 29, each of which pivotally supports a bell-crank finger 22 having a curved bearing portion. A garter spring 35 is provided around a set of fingers to urge them inwardly and an annular bearing member 36 engages the fingers to move them against the spring to allow loading of the tube and fins. Each member 36 is secured to a pair of bars 38 movable by a pneumatic piston-and-cylinder device 44, 45 through levers 42. In operation, the end of a tube T is secured by a set-screw inside a hollow guide member 50 and U-section fin members 11 are inserted between the body of the guide member and resiliently urged fingers 62 to be clamped to the tube. The assembly is then pushed through the sets of fingers which have been retracted by the piston cylinder device 44, 45 to fit within the channels but do not engage the bottoms thereof and the piston cylinder device 44, 45 is then actuated to retract the bearing members 36 so that the fingers 22 of all the sets engage firmly the bases of the channels. Brazing metal supplied by previously tinning the fin members or by winding a snip of brazing metal on the tube before the fin members are assembled is melted by passing a gas burner 48 such as that disclosed in Specification 656,187 through the tube. The soldering or brazing operation may be silver soldering or copper brazing.

Filed: 1927-12-14
Abstract: 282,417. Parker, R. B. Dec. 14, 1926, [Convention date]. Charging and discharging; cooling discharged materials. -Charging apparatus for a vertical retort 4 is arranged to supply fuel without opening the retort to the atmosphere and comprises superposed hoppers 24, 29 having bell valves 25, 30 carried respectively by a rod 26 and a hollow shaft 31. To the shaft 31 and the rod 26 respectively are secured pistons 28, 33 disposed within fluid pressure cylinders 27, 32, the fluid supply being so controlled that when one valve is open the other is closed. To prevent lodgement of fuel between the bells 25, 30 and their seats, the bells are formed with roughened projecting portions 30a adapted to bear against the sharpened lower edges of steel rings 23<1>, 25<1> fitted in the bottoms of the hoppers. The cylinder 32 is of sufficient length to allow the valve 25 as it moves downwardly, to contact with and thus compress the fuel in the retort. The apparatus is described as applied to a retort having discharging means, gas offtake device, and a grate structure as described in Specifications 282,415; 282,418, and 282,419, [both in Class 55 (i), Coking &c.], respectively. The pistons 28, 33 may be automatically actuated as described in Specification 282,415.

Patent GB-467571-A (GB)
Title: Improvements in the manufacture and production of condensation products
IPC: C08G63/685
Filed: 1935-12-16
Abstract: Condensation products are obtained by reacting resin alcohols, e.g. abietinol, di- and tetrahydroabietinol, or resin amines, e.g. abietinylmethylamine or their acyl derivatives, e.g. acetyl-abietinylamine, containing the groups --NH-- or NH2, with alkylene oxides, e.g. ethylene-, propylene- or butylene oxides, epichlorhydrin, glycide or glycidic acid.  The process is preferably carried out while heating and, if desired, with the addition of alkalinereacting or reactive substances having catalytic action, e.g. sodium hydroxide, potassium hydroxide, sodium acetate, sodium ethylate, bleaching earth, e.g. tonsil, or active carbon.  The products may be used as alcohol-soluble resins, softening-agents for lacquers &c., carriers for perfumes and dispersing agents.  Products with free terminal hydroxyl groups may be further reacted, e.g. with sulphonating agents, e.g. sulphuric or chlorsulphonic acids, or condensed with carboxylic acids, e.g. chloracetic acid, glycocoll or maleic acids.  In examples: (1) dihydroabietinol is heated with potassium hydroxide to 120--160 DEG  C. in a stirring autoclave and ethylene oxide is pressed into the melt in portions under a pressure of 2--10 atmospheres to produce a sticky resin soluble in alcohol, which may be further reacted with phthalic or maleic anhydrides; (2) dihydroabietinol is heated with potassium ethylate to 150--160 DEG C. and ethylene oxide is led in a little at a time in the gas phase to produce a wax-like product which may be further reacted with succinic anhydride to yield a product having good adhesive properties; (3) a resinous, adhesive product is obtained from dihydroabietinol and epichlorhydrin which product may be further reacted with trimethylamine; (4) a mixture of di- and tetra-hydroabietinol, heated with sodium hydroxide to 170 DEG  C. is treated with ethylene oxide under pressure to produce a wax-like product or, with increased quantities of ethylene oxide, a water-soluble product useful as a non-foaming levelling agent for dyeing.

Solid or viscous isocyanates are employed as organic solvent solutions. Specified tertiary amines are trimethyl and triethyl amines and dimethyl ethanolamine. They may be used as such or diluted in an inert gas. The binder usually constitutes less than 10% of the foundry mix, and other additives may be included, e.g. alkoxysilanes, iron oxide, ground flax fibres, wood cereals, pitch and refractory flows.

Abstract: 960,366. Liquid pressure engines. KEELAVITE HYDRAULICS Ltd. Oct. 19, 1960 [Oct. 20, 1959], No. 35594/59. Heading F1A. In an hydraulic motor comprising a doubleacting piston and cylinder assembly controlled by a fluid pressure actuated shuttle valve, change-over of the valve is effected when the piston uncovers ports in the cylinder wall connecting a working chamber of the motor and a relief line respectively to appropriate end faces of the valve. In the position shown pressure fluid enters a working chamber R via ports 13, 23, 10 and 8 to move piston assembly 2, 3 to the left, a working chamber L being relieved via passages 7, 22 and 16. Shuttle valve 12 is maintained in position by the action of pressure fluid on a fixed piston 29 in a cylinder 27 within the valve, via passage 31, the right-hand chamber of the valve being relieved via ports 32, 33, 14 and 16. Towards the end of the leftward stroke piston 2 uncovers a port 34 to connect chamber R to the lefthand end of the valve for change-over, the area of the valve end face being greater than that of the holding piston 29. Concussion at the end of the valve movement is prevented by positioning the passage 31 of holding cylinder 27 so that fluid is trapped in the end of the cylinder by piston 29 towards the end of the valve movement. The fluid pressure acting on the shuttle valve to effect change-over is made sufficient to move the valve rapidly against the effect of any depression created in the holding cylinder. The motor piston may be fixed and the cylinder move or vice-versa or both piston and cylinder may move in opposite directions.
