Title: Improvements in Soldering Composition Paste.
Inventor: BRACH LEON ST CLAIR
IPC: B23K35/26
Filed: 1911-08-16
Granted: 1912-07-25
Abstract: 18,513. Brach, L. St. C. Aug. 16. Soldering.-A soldering - composition paste consists of powdered tin and lead mixed with zinc chloride and water and with a carrier. of rarefied petrolatum and with or without zinc and resin. The solder particles are stated to be held in fixed relation towards one another. The paste can be stored in collapsible tubes, which are squeezed to allow the paste to be applied to the work. It is formed by mixing 20 parts of zinc chloride with 10 parts water, then adding 35 parts refined petrolatum, and after stirring, adding 30 parts unrefined petrolatum and again stirring. Five parts of resin may be added to the mixture by first liquefying and then mixing it with petrolatum and stirring into the whole mass. Zinc may be used to neutralize any free hydrochloric acid. Three parts of solder consisting of powdered tin and lead, in proportions according to the nature of the work to be treated, are stirred into one part of the mixed flux and carrier to complete the paste. Other proportions may be used.

Title: Improvements in Machines for Covering or Insulating Wire with Yarn or its Equivalent.
Inventor: NOBLE DONALD
IPC: D07B7/14
Filed: 1911-08-18
Granted: 1912-02-08
Abstract: 18,674. Noble, D. Aug. 18, 1910, [Convention date]. Wire, covering by winding.-In machines for covering or insulating wire, of the kind in which the spinning-head carries rolls that pay out the yarn &c. to the covering-devices at a tension less than that required to draw the yarn from the cop itself, the rolls are disposed in such a manner that the centrifugal force produced by the rapid revolution of the spinning-head is counteracted. The hollow hub 3 of a spinning- head 2 is secured to a power shaft 1, and is loosely surrounded by a bushing 7 carrying the tube 6 of a yarn cop 5. A tension device of known kind comprises a spring finger 9, which presses the cop against the inclined rear wall of the head 2, and provides a constantly diminishing tension upon the yarn as the diameter of the cop decreases. A casing 11 secured to the head 2 is provided, as shown in Fig. 4, with bearings for spindles 18, upon which are worm-wheels 19 gearing with a stationary worm 12 supported loosely by the shaft 1. An extension 13 of the worm 12 provides a bearing for the shaft 1. Yarn delivery rolls 20 on the spindles 18 extend through the rim 10 of the spinning-head in planes that are inclined to tangents to the rim. Yarn-guides 21 may be placed near the rolls 20, as shown in Fig. 2, for aiding in keeping apart the coils of yarn around the rolls. The yarn passes from the cop through the rim 10, over a guide-stud 23, then around the rolls and guides as shown in Fig. 2, and finally to the winding-nozzle 24. Slipping takes place between the rotating rolls 20 and the varn so that there is a tendency to pay out too much yarn to the winding-nozzle. The centrifugal force pulling the roll spindles outwards is counteracted by the tendency of the spindles to hug their bearings under the action of the stationary worm 12.

Title: Improved Process of Making Metal Foil, applicable for use in Storage Battery Electrodes.
Inventor: HUBBELL HARRY CROSS
IPC: H01M4/64
Filed: 1911-10-03
Granted: 1912-02-22
Abstract: 21,784. Hubbell, H. C. Oct. 3. Electrodes.-Thin foil or ribbon metal, such as nickel, cobalt, or iron, suitable for addition to the active material of electrodes for alkaline accumulators is made from a book composed of alternate leaves of nickel or the like and a metal such as copper, tin, or cadmium, by pressing to the necessary thinness and then removing the intermediate metal. Pressing may be effected by rolling, preferably after the book has been heated until the copper or equivalent metal solders the whole together. A sheet of iron or other more refractory metal may be interposed between two sheets of copper between each pair of nickel sheets, to prevent these from touching when the copper melts. A book may comprise 8 or 10 sheets, each 1/32 inch thick, composed alternately of nickel and of copper previously dipped in borax solution; it may be rolled until each nickel sheet is reduced to a thickness of 1/3 000 or 1/4 000 inch. The resulting compound sheet may be cut into small strips, and is then freed from the auxiliary metal. Iron is removed by acid ; copper by solution in potassium cyanide, or by electrolysis, either in a solution of ammonium and sodium acetate containing ammonia, or preferably in disodium ammonium phosphate solution kept alkaline by ammonia, the copper being deposited upon a copper, iron, or nickel cathode; cadmium may be volatilized in the absence of air; and tin may be dissolved in alkali.

Title: Improvements in Rotary Engines, Pumps and Compressors.
Inventor: WEED HOWARD LAWRENCE
IPC: F01C1/063
Filed: 1912-03-26
Granted: 1913-02-06
Abstract: 7391. Weed, H. L. March 26. Movable-abutment type; cooling parts; starting; packing drums and vanes; working-fluid supply.-Relates to rotary engines, pumps, &c. of the type in which the vanes act alternately as pistons and abutments, the vanes being connected to one another and to the shaft by a differential gear. The vanes 14, 14', 15, 15<1> are mounted on sleeves 16, which are formed with bevel teeth 19 arranged to mesh with the epicyclic pinions 20 carried by a collar 22 fixed to the shaft 2. Backward motion of the vanes is prevented by spring-pressed detents, and the forward motion is controlled, on the functions altering, by catches operated by geardriven shafts 105. Figs. 1 and 2 show an internal-combustion engine working on a fourstroke cycle. Mixture is drawn in at 90, and fired after compression by a sparking-plug 94, the exhaust being discharged through casing ports 84. Cooling is effected by a fan 60, which discharges air against ribs 66 and also into a passage 79 which communicates with the interiors of the pistons. A partition 69, and ribs 71 cause the air to circulate and to be finally discharged into the atmosphere, but periodically the air passed into the pistons is caused to pass through holes 83 in the pistons into the working chamber in order to scavenge it. Roller and ball bearings arc provided at various points, and a gear-driven magneto 96 is connected with the sparking-plugs. Packing- devices are provided on the pistons and at the points where the piston-drums contact with one another and with the casings. The casing halves 1, 1<1> are clamped together by clamps 6. A friction cone 126 on the shaft 2 gears with a cone 125 on the shaft 119 carrying a flywheel 118. In order to start the engine by hand, a cone 127 is loosely mounted on the shaft 2. A bevel-gear 131 on this cone is driven by a gear on a shaft which is rotated by hand. On starting, the bearing 120 of the shaft 119 is moved against the action of a spring 122, so that the cones 125, 127 are in gear. When the fly-wheel 118 has acquired sufficient momentum, the bearing 120 is moved back, and the cone 125 then drives the shaft 2.

Granted: 1914-01-05
Abstract: 27,956. Johnson, G. W., [Heracus Ges., W.C.]. Dec. 4. Electro-magnetic switches.-Relates to electromagnetic switches, employed for starting mercury-vapour and other electric lamps, electric motors, &c., of the kind in which a switching- armature is acted upon by two magnetic poles energized by a common winding, and is attracted by one or the other pole according as the current in the winding exceeds or falls below a determined value. According to the invention the switching device comprises a pivoted lever carrying a contact-piece k<1>, Fig. 1, and an armature a<1>, the armature end projecting between two like magnetic poles p, S disposed parallel to each other and energized by a common winding. The armature a' is attracted by the pole p when the current exceeds a determined value, and the switching-over is effected by the pole S, which constitutes a dispersion pole with respect to the pole p, when the current intensity decreases to a certain value. In the modification shown in Fig. 2, a second armature a<2>, branched off the main one, is attracted by the pole p when the switching-over occurs, to reinforce the action. An adjustable stop b controls the position of the armatures and determines the current value at which the switching- over occurs. In the form shown in Fig. 3, a weighted armature a<2> normally holds the main one a<1> in the off position. When the current is switched on, the pole p<1> attracts the armature a', and the pole p<2>, which may belong to a separate magnet or to the same magnet as the pole p<1>, lifts the armature a<2>. When the current intensity falls, the armature a<2> is still maintained attracted and the pole S causes the switching-over of the armature a<1>. A small series winding of oppositive magnetomotive force may be placed on the pole S to weaken its effect.
