IPC: F28F1/12
Filed: 1966-07-15
Abstract: 1,125,822. Heat exchange apparatus; air heaters; water heaters; boilers. D. DALIN. 15 July, 1966 [20 July, 1965], No. 31834/66. Headings F4A and F4S. In a vertical boiler 5 pin fins 18, for assisting heat transfer from combustion gases through the wall 22 to the water, comprise rods or wires having copper cores 19 with iron sheaths 20, the percentage of copper in the rods and hence the thermal conductivity thereof decreasing from Group I where the gases are hottest to Group IV where they are coolest. In another form the fins are flattened fingers joined together by a continuous edge, said edge being connected to the wall. The core may be iron and the sheath copper. In another embodiment the thermal conductivity is decreased by the fins being hollow copper tubes and successive fins being of decreasing wall thickness. The fin at one end may be solid iron and the other solid copper, and aluminium may be used instead of copper for some of the cores. The pin fins are also used on either side of the wall separating the flue gases and the air being heated in a direct fired air heater (Figs. 3-5). The air chamber is divided into successively communicating passages such that the air being heated flows downwardly countercurrent to the rising combustion gases. The fins are also used on the serpentine tube of a water heater (Figs. 6, 7).
Patent GB-534099-A (GB)
Title: Automatic vending machine
IPC: G07F5/08
Filed: 1939-12-09
Abstract: 534,099. Article-delivery apparatus. PARNALL & SONS, Ltd. Dec. 9, 1939, No. 31886. Convention date, Dec. 13, 1938. [Class 27] In coin-freed vending machines in which a plurality of receptacles, such as sliding drawers, from which the goods are taken, dispense the goods at various prices, a single change-delivering device is provided for any number of coins without its being necessary, in the case of goods below the highest price, to add, in advance, the change to the packages to be dispensed. The drawers 1 are each held against opening by a tooth 3a on a pivoted lever 3 pressed upward by a spring 4. A series of bars 27, one for each drawer, abut against one another and can be moved axially so as to leave a gap between any two of the bars. The bars normally hold up the levers 3 but when a lever is pressed down by the edge of the drawer slot bearing against the inclined rear face of the tooth 3a when the drawer is pulled out, it forces the two abutting bars 27 beneath that drawer apart, and so closes the remaining bars together to prevent another gap being formed and another drawer contemporaneously opened. Below the drawers extend two shafts 8, 9, on the front one of which are mounted arms 25 with which contact pins 5, 6, of different lengths, depending from the levers 3, engage. For the insertion of coins of one kind a receiving receptacle 12a and shoot 12 is provided. Into the front side of the shoot project three holding faces 13b, 14b, 15b mounted on three bell cranks 13, 14, 15 swinging on a shaft 16 and drawn by springs 17 to press the faces 13b, 14b, 15b inward. Co-operating with these faces are three projections 19b on a coin-releasing lever 19 also swinging on the shaft 16 under the influence of a spring, and three inserted coins form abutting connections between these parts and rest, before release, on the turned-in lower edge of the face 15b. On the shaft 16 is also pivoted a cranked lever 18 having at its top a turned-over edge 18a which, when the lever is rocked by a releasing lever 10 on the shaft 8 striking against a pin 18c, contacts successively with the inclined tops 13a, 14a, 15a of the cranks 13, 14, 15, thus swinging them outward without the insertion of a coin. A similar releasing lever 11 on the shaft 9, with one bell-crank 21, is provided for the shoot 20 which is intended to receive one coin of a higher denomination. The pins 5, 6 determine the amount of movement or stroke of the releasing means, and may be adjustable or interchangeable. In a modification the bell-cranks 13,14,15 are thrown out of action simultaneously by the releasing lever. Three shafts are then provided instead of one shaft 9, each of them carrying a releasing lever which lies in the path of a pin, all of the pins being of equal length.

Title: Improvements in or relating to the recovery of gold from pyritic ores
IPC: B03D1/02
Filed: 1920-11-11
Abstract: 175,384. Lemmon, R. J., Sulman, H. L., and Minerals Separation, Ltd. Nov. 11,1920. Surface-tension separating processes.-Gold is recovered from pyritic ores by froth flotation, using a pulp which is neutral or slightly alkaline, and a frothing-agent which contains phenol or cresol or both, preferably unwashed coal tar or wood tar, with or without the addition of cresol or blast-furnace creosote or both. There may also be added to the pulp a small proportion of one or more paraffin hydrocarbons such as paraffin oil. The gold is obtained accompanied by the pyrites. In some cases, after applying a flotation process or not, the pulp may, as described in Specification 26019/09, be treated with a soluble salt such as ferrous sulphate, and a sulphide then added to precipitate ferrous sulphide in the pulp, whereupon a flotation process is applied. The concentrates obtained may be retreated by a flotation process, and the gold and pyrites afterwards separated by known methods.

Title: Improvements in electrodes or welding rods for use in electric arc welding
IPC: B23K35/04
Filed: 1932-11-11
Abstract: 404,122. Uniting by fusion. QUASIARC CO., Ltd., and STROHMENGER, A. P., 15, Grosvenor Gardens, London. Nov. 11, 1932, Nos. 31974/32 and 3012/33. [Class 83 (iv).] Arc welding electrodes or welding rods provided with a coating containing cellulose are submitted to a heat treatment to effect a partial decomposition of the cellulose while leaving a residue capable of producing a protective atmosphere in the arc. A large proportion of the gases evolved thereby are thus removed while retaining the cellulose in a cohesive non-friable form. The coating may consist of a winding of cotton impregnated with solutions or emulsions of metallic salts, clay, &c., or a helically applied mixed cotton and blue asbestos yarn, or a braided yarn of mixed cotton and blue asbestos fibres. The core may also be coated first with cotton or other cellulose material and then with a slag forming material such as a mixed yarn of blue asbestos and cotton. The electrode is first heated to about 120‹ C. to expel moisture from the coating and is then heated to not less than 250‹ C. or more than 320‹ C. to effect the partial carbonization of the cellulose. This may be effected in an oven in the absence of external air, the removal of the products of distillation being assisted by a fan. The electrodes may pass on a conveyer through an oven, the first part of which has a low temperature and the succeeding parts a higher temperature. When mixed cotton and asbestos fibres are used the treatment is effected in an inert or reducing atmosphere to prevent oxidation of the asbestos. The cotton fibres may constitute about One third of the weight of such yarn. The total loss of weight after heat treatment may amount to 50 per cent of the cellulose in the covering. With such an electrode a core containing 1.5 per cent of manganese yields a deposited metal containing 0.5 per cent of manganese.

Suspensions. - A multi-filar suspension for the moving systems of measuring - instruments comprises two or more filaments with a distance piece or pieces located between the ends thereof f and terminal plates which with the filaments form a unitary structure. The distance-pieces present curved surfaces to the filaments to prevent bending thereof and constitute a means for equalizing the tension between the filaments. In one form as applied to a watt-meter, shown in Figs. 1 and 2, the moving system 7 is supported on a vertical spindle 8 which is attached to the lower insulated terminal plates 23 of the " bifilar ladder" 29, 30. The upper isulated terminal plate 23 is carried by a member 22 mounted m knife-edge bearings 19 on an extension 18 of the spindle 17 adapted to be rotated by worm gearing 16, 20 supported by a three-legged insulated bracket 13. To the upper plate 23 are attached two metallic strips 24 connected by flexible wires 25 to terminals 26 and by screws 28 to metallic plates 32 mounted in insulating plates 31 and electrically connected to the filament 29. A member 38 on the spindle 8 carries a pointer 36 and a mirror 40. Various forms of distancepieces 30 are shown in Figs. 6, 7<a>, 7<b>, 7<c>, and 7<d>; the forms shown in the Figs. 7<a>, 7<c>, and 7d serve also as means for equalizing the tension in the filaments, but in the case shown in Fig. 7<d> the filaments are discontinuous. In an alternative construction the moving system is carried by silk filaments and auxiliary metallic filaments are employed for conveying the current to the moving system. To facilitate handling of the " bifilar ladder " during its assembly or withdrawal, a frame having means to engage the terminal plates is provided to support it temporarily. According to one Provisional Specification the distance-pieces may be made of fine glass fibres coated with wax and fixed in position by stretching the filaments on a frame and tying the fibres in pairs, one on either side, and applying a hot wire to melt the wax. Also, to modify the tension of the filaments, springs or weights may be added or the filaments may be attached to a pair of spring bows in order to adjust the separation thereof.

Title: Improvements in liquid dispensing apparatus
IPC: B67D7/16
Filed: 1930-10-29
Abstract: 365,221. Dispensing liquids. GILBERT & BARKER MANUFACTURING CO., Cold Springs Avenue, West Springfield, Massachusetts, U.S.A. Oct. 29, 1930, No. 32534. Convention date, Nov. 15, 1929. [Class 116.] In liquid-dispensing apparatus of the type in which movement of a lever controlling the pump is prevented when the hose-nozzle is placed on its support, the support is external of the apparatus and is so arranged that a member on the nozzle projects into the path of the lever. Movement of this lever also operates a valve controlling the passage of liquid to a flow meter and thence to the hose, and when two such discharge systems are provided, movement of either lever to active position will close the pump-switch, while movement of both levers to inactive position is necessary to open the switch. A pump 21, Fig. 1, operated by a motor 25 having a switch 32, delivers from an underground tank through pipes 33<1>, 34 and valves 38 to meters 36 and thence by pipes 43 to sight-glasses 44 and flexible hoses 45 furnished with nozzles 46. A lever 33 of the switch 32, Fig. 5, carries members 81 in which slide links 79 provided with shoulders 80 ; the links 79 also slide in heads 70 carried by arms 68 which are each connected through an arm 71 sliding in a head 69 to the operating lever 40 of the corresponding valve 38. Each arm 68 is connected to a shaft 62 carrying a lever 61, movement of which is prevented when the nozzle is on its support 57 owing to the engagement therewith of the nozzle-guard 48. A member 58, apertured to receive a padlock, projects through a slot in the guard and thereby also prevents operation of the nozzle-lever 47. The switch 32 is of the self-opening type, the pivots 70 being arranged to cross, on operation of the apparatus, the plane through the pivots 62, 81 to maintain the switch in open position.
