Abstract: 347,862. Wire wheels. BUDD WHEEL CO., 2500, Hunting Park Avenue, Philadelphia, U.S.A.-(Assignees of Tarbox, J. P. ; 2500, Hunting Park Avenue, Philadelphia, U.S.A.) April 16, 1930, No. 12023. Convention date, April 19, 1929. [Class 144 (i).] The wire spokes of a vehicle wheel are preformed in two or more continuous series and are afterwards interconnected with the rim and hub to form the wheel. Tension may be applied to the spokes when they are connected to the hub. In one form, shown in Figs. 1 and 2, the spokes are formed of two groups wound on dies, an inner group 21 and an outer group 20, each formed by prewinding from continuous stock to the shape shown and with the ends welded at bights 24 of one of the inner loops connecting adjoining spokes. These groups of spokes are assembled with a rim in two parts 25, 26, depressions 28 being formed on one or both flanges 27 on these parts to take the outer bights 22 between adjoining spokes. The hub 29 is provided with tines 31 of the width of the bights 24 and also of the spaces between the bights and have their ends turned inwardly towards the wheel axis whereby the spokes are held in place and tensioned. A hub cap is forced on, tines thereon gripping the hug. Spring clips may also assist in holding the cap in position. The spokes, rim, and hub are assembled in a welding jig, as shown in Fig. 5, with the inner part 26 of the rim held by a flange 27 on the top of an outer welding die 38. An axially movable inner concentric die 39 with fins 40 adapted to enter the kerfs between the tines on the inner end of the hub shell 29 is also provided. The inner group of spokes 21 is laid with its loops 24 on the fins 40 and the loops 22 in the bosses 28 and the hub shell 29 is positioned on a concentric arbor 41 of the jig. The outer group of spokes 20 are next placed in position with the tines 31 projecting through and between the loops 24 thereof and finally the part 25 of the rim is assembled. An upper welding die 42 is then positioned and a portable welding tool 44 is employed to spot weld the rim parts 25, 26 between the loops. Simultaneously, an upper concentric inner die 45 similar to the die 39 is lowered into position to force the bights of the loops 24 into the kerfs between the tines and to tension the spokes. The assembled parts are then transferred to a closing-in machine of the form shown in Fig. 6, wherein the hub shell 29 is centred on an arbor 46. Segmental radiallyacting dies 47 on this machine have their ends shaped to engage and gradually turn-in radially and close the tines 31, and finally tension the spokes. The invention is described also as applied to wheels having other forms of rim, and hub shell.

A blade assembly 70 for a multiple-blade sawing-machine for cutting hard materials such as quartz, silicon or germanium comprises a plurality of blades 73 separated at their ends by spacer elements 71 bonded to the blades. The blade assembly is mounted in a reciprocable frame 20 comprising side members 25, 26 and end members 27, 28 screwed together, the end member 27 being formed with a flange 41a, which, together with another flange 42a formed on a clamping member 47, forms jaws in which one end of the blade assembly is gripped. The other end of the blade assembly is gripped by means of a member 31 having a flange 41b and a clamping member 48 having a flange 42b, the member 31 being movable under the action of screws 38 in order to tension the blades in the frame; the blade assembly is locked sideways in the frame by means of clamping screws 53a, 53b acting against blocks 62a, 62b. In operation, abrasive slurry is applied to the blades. After a period of use, the blade assembly may be turned over in the frame in order to bring the other longitudinal edge of the blades into contact with the material to be cut. In order to produce an accurate blade assembly the bonding of the spacers 71 to the ends of the blades is effected in a jig 81 comprising a baseplate 81a having, at one end, a removable block 85a in which the spacers 71 and blade ends are alternately arranged and located as shown in Figs. 3 and 4; the spacers being clamped sideways by means of a screw 112a, and block 111a and downwardly by means of a plate 101a via screws 107. At the other end of the base-plate a similar clamping arrangement is provided, the screws 107 for the plate 101b being screwed into a slidable member 81b mounted in the baseplate. The blades are pulled parallel with each other by moving the member 81b by means of a screw 95.

Title: A process for the production of readily soluble calcium salts
IPC: A61K33/06
Filed: 1939-04-21
Abstract: 527,864. Medicinal preparations of calcium salts. FIFE, J. G. (Wulfing, G. A. R. von, and Rosskothen, E. M. H., [trading as Wulfing, J. A.]). April 21, 1939, No. 12088. [Class 81 (i)] [Also in Group IV] Readily-soluble calcium compounds stable in solution are obtained by reacting calcium lactate with sodium gluconate or calcium gluconate with sodium lactate ; for instance, neutral supersaturated solutions of calcium gluconate or lactate can be stabilized by adding sodium lactate or gluconate respectively. Preferably equivalent quantities of the salts are employed. Alternatively the acids may be neutralized with equivalent quantities of calcium and sodium hydroxides, oxides or carbonates. The solutions may be evaporated to dryness under reduced pressure, or a solid product may be obtained by adding one of the salts in solid form to a concentrated solution of the other. In examples (1) sodium lactate is added to a hot solution of calcium gluconate or lactic acid may be added to the calcium gluconate solution which is then neutralized with sodium carbonate; (2) a solution of gluconic acid lactone which has been neutralized with sodium carbonate is added to a solution of calcium lactate ; (3) calcium gluconate is mixed with a 60 per cent solution of sodium lactate and allowed to stand until the mass is dry; (4) calcium lactate is dissolved in a solution of gluconic acid lactone which has been neutralized with sodium carbonate; the crystalline mass produced in standing is dried in vacuo. It is stated that it is known to stabilize solutions of calcium gluconate by adding substances such as calcium mannonate, calcium salts of keto-acids such as the laevulinate, sodium thiosulphate, boric acid, and calcium saccharate, and that it has been proposed to stabilize the solutions by adding the calcium salts of bionic acids, calcium chloride or calcium formate with the formation of double salts:

Abstract: 1343136 Electrically heated pipe-lines W J TRABILCY 29 April 1971 [15 May 1970] 12175/71 Heading H5H A liquid-conveying pipe-line 25 is heated by the passage of A.C. through a predetermined portion of the outer periphery. An insulated conductor 22 is positioned along the outer periphery of the pipe-line 25 and is covered by an electrically conductive shroud 24, which may be an angle iron. Connections are made at 48 and 55 such that alternating current from a source 20 flows through the conductor 22 and then back through the shroud 24 and a portion 44 of the pipe-line 25, the current being concentrated in the outer periphery of portion 44 and inner periphery of shroud 24 by the skin effect. Pressurized oil in space 46 improves conduction of heat to the pipe-line and serves to detect leaks, Figs. 8, 9 (not shown). Two conductors 22 in parallel may be used to increase the heating capacity, Fig. 4 (not shown), or the conductor 22 may loop back and pass through a second shroud 100, Fig. 5, the latter arrangement cancelling any small current leakage and preventing electrolytic action on the pipe-line or associated equipment. A temperature-responsive control circuit 32 compensates for temperature-induced variations in the electrical resistance of the pipe-line 25 and shroud 24. The shrouds are welded continuously or at intervals to the pipe-line, or are held in place by straps or bands. The shroud 24 may be a three-sided channel member or be curvilinear in cross-section, Fig. 7 (not shown).

April 22, 1930, No.' 12405. [Classes 100 (i) and 100 (ii).] A machine for printing on and forming closing caps for ice-cream and like containers comprises mechanism for feeding a strip of material through a printing-machine to apparatus which punches out the printed blank and forms it into the cap shape. The strip .79 is advanced from a roll to the operating mechanisms by rollers 80, 87, 88 which are driven intermittently by toothed gearing from a shaft 96 coupled to a continuously-rotating driving shaft 11 through a Geneva mechanism. An adjustable spring presses the roller 88 towards the roller 87. The waste material may be wound on an intermittently driven spindle journalled in the lower part of the machine frame 1. Inking-apparatus.-The printing device consists of a printing plate 77 mounted in a recess in the periphery of a roller 78 fixed to the shaft 11 and coacting with an impression roller 95<1> freelymounted on the shaft 96. Ink is applied to the plate 77 from a composition roller 70 supplied from an ink duct 22 through axially-reciprocating steel rollers 61, 53 between which ink is conveyed by a composition roller 62, the roller 53 being supplied from the duct-roller 24 by a messengerroller 52 on an arm 49 oscillated from a cam shaft 39. The duct consists of a blade 21 pressed by a screw 20 against the roller 24 which is rotated by pawl-and-ratchet gearing 28, 29 from the shaft 39 through a spring-controlled lever 33 and links 32. An arm 45 fixed to the shaft 34 of the lever 33 contacts with a set-screw 48 adjustable so as to limit the swing of the lever 33. Gearing on the shaft 39 rotates the rollers 53, 62, 61, 70, and inclined discs on the endwise-movable shafts 54, 60 of the rollers 53, 61 engage a grooved roller 57 on a stub-shaft 58 so as to cause axial reciprocation of the rollers 53, 61. Bearings 64 adjustable by screws 66 are provided for the roller 62, and the roller 70 is carried by an adjustable arm 72. In a modification, the entire inking-apparatus is carried in brackets pivoted to the main framing and adjusted by a bolt-and-slot connection so as to vary the position of the roller 70 relatively to the printing plate 77. Cupping-apparattus.-The printed strip passes between die-plates 106, 109 grooved to receive it, and a punch sleeve 107 operated from a cam 130 on the shaft 11 through a bell-crank lever 136 co-operates with the die-plates to punch out a printed blank. Within the sleeve 107 is mounted a plunger 112 pressed outwardly by a spring 140 and similarly operated from the shaft 11 so as to co-operate with a reduced part 111 of the plate 109 to form the blank into a cup-shaped cap. The cape are received in a carton 114 removably fitted into a recess 113 in the plate 109.

Abstract: 493,957. Electromagnetic switches. CRABTREE & CO., Ltd., J. A. (Schiele Industriewerke) May 1, 1937, No. 12459. [Class 38 (v)] The moving contact 1 of an electromagnetic switch is gripped between two levers 2a, 2b which are pressed towards each other by a spring 3, the arrangement being such that when the contact 1 engages the fixed contact 5 due to the energization of the magnet 9, further movement of the lever 2a, which is fixed to the armature 8a, causes the contact 1 to pivot about a point 2s on the lever 2a and force the levers 2a, 2b apart, stressing the spring 3 and ensuring good contact pressure. In the form shown, the spring 3 is a compression spring and bears at its left end against an abutment on a pin 4 anchored to the lever 2b. The lever 2a pivots about a fulcrum 7 and the lever 2b bears against and pivots about an angle piece 11 carrying a terminal 12. The contact 1 has a groove 1b engaged by the upper end of the lever 2b. Hinge pins are thus avoided and in the closed position of the switch, current flows from the terminal 12 through the lever 2b to the contacts 1, 5 and thence through an overload release 14 to a terminal 15. Should an overload occur, the release 14 operates to break the circuit of the magnet 9 and the armature 8a and lever 2a move to open the circuit.
