Abstract: 618,121. Making electric resistances. BEHM, E. M., and BEHM, A. J. E. Oct. 22, 1946, No. 31383. [Classes 83 (ii) and 83 (iv)] Coiling.-In a machine for winding simultaneously a filament on to two formers to form electric heating elements, chucks rotate and grip the formers end to end and wire guides wind the legs of a looped filament on to each former. The formers 2, 2 are held in alignment in chucks 3 rotated from a driving shaft 13 and are supported at adjacent ends by a centre chuck 4 rotated from the shaft 13. The filament is led from a bobbin 5 and the free end attached to a clip 53 on a cord 47 attached to a mass 49. A loop is formed on the filament and it is threaded through a hole in the centre chuck 4 and anchored on a pin 55. The legs of the loop are threaded in wire guides 6 moved apart during winding by screws 8, 8. Discs 70 with spring-pressed rollers 68 move with the wire-guides during winding to steady the formers. At the end of the winding, members 64 are raised to disengage the lead screws, wedges open the steady rolls 68 and a projection on the carriage throws out the clutch. The lead screws may be of variable pitch for winding filaments of non-uniform pitch.

Abstract: 447,730. Starting ; valve gear. KRUPP GERMANIAWERFT AKT.-GES., F., Kiel, Germany. Nov. 13, 1935, No. 31392. Convention date, Nov. 30, 1934. [Classes 7 (v) and 7 (vi)] In a multi-cylinder Diesel or other engine in which starting valves b<1> ... b4 are actuated by compressed air supplied through pipes g<1> ... g4 from a distributer f, the pipe g<1> leading to the valve of the nearest cylinder has a comparatively small and substantially constant diameter, while the pipes g<2>-g<4> leading to the more distant cylinders are stepped in diameter so that the compressed air in each pipe will travel from the distributer to the respective valves in substantially the same time. All the pipes have the same internal diameter where they communicate with the valves, and the length of the narrowest portion of each pipe is such that the quantity of compressed air required to fill it would, under atmospheric pressure, fill the whole pipe from the distributer to the valve. As shown, the distributer f is actuated by a cam on a shaft m driven from the crank-shaft h through bevel gearing k. A compressed-air main c is connected by branches d<1> .. d<4> to the starting valves b<1> ... b4 by a pipe e to the distributer f.

Title: Improvements in and relating to the regulation or control of alternating currents
IPC: G05F1/12
Filed: 1927-11-22
Abstract: 310,296. Porter, G. L., and Ferranti, Ltd. Nov. 22, 1927. Regulation, automatic.-In systems for maintaining constant the voltage of alternating-current circuits, a voltage-regulating direct-current relay is connected in a differential circuit in which a steady voltage is opposed to a rectified voltage. A rectifying network a, Fig. 1, replaces the usual alternating-current relay and feeds a resistance potential-divider e through a filter b. The rectified voltage in an adjustable part of the resistance c normally balances the voltage of a battery e in the coil f of a polarized direct-current relay, variations in the rectified voltage operating the relay to close one of two circuits for raising and lowering the alternating voltage. A second circuit including a resistance h charges the battery. The coil f may be on a metallic former to increase the damping. In a modification, Fig. 2, the steady voltage of the battery e is always just below the rectified voltage from the rectifier a and an unpolarized relay f is used. A loading resistance m ensures that the rectifier a works at a suitable point of its resistance characteristic. Current always flows through the relay f towards the battery e and a resistance n is provided so that the battery floats. The Provisional Specification describes a system in which a transformer has its primary connected to the circuit to be regulated and the ends of its secondary connected through rectifiers to a filter circuit connected to the mid-point of the secondary.

Filed: 1954-11-09
Abstract: 765,894. Coating processes. MEISTER, W., and MEISTER, A. Nov. 9, 1954, No. 32342/54. Class 95 [Also in Group VIII] In a method for tightening textile hoses or tubes, these are. filled at least once, with a liquid containing a tightening material such as rubber solution or latex and are then emptied and the tightening material adhering to the inside of the hose is dried, the hose being filled with water under pressure before filling the same for the first time with the liquid containing the tightening material. Prior to the treatment with water under pressure flat and/or loosely woven or plaited hoses may be externally treated by passing through a bath of a rubber containing solution after which they are pressed to bring the liquid content of the fabric to a desired value. Flat hoses or tubes, after external treatment, are subjected to compression in the direction of the longer axis of their section to transform the latter to be approximately quadrilateral with rounded edges. As shown, a hose 1, Fig. 1, having a flat section, Fig. 3, is subjected to pressure as shown by the arrows F, Fig. 1, whereby its section is transformed into that shown in Fig. 4. The hose then passes between parallel bars 2, Fig. 1, through a rubber containing bath 4, over pulley 5 and guiding bar 6 and then through the nip between pressing cylinders 7 where the section is deformed by opening the original folds 1a and forming two new folds 1b as shown in Fig. 7. Thereafter the hose assumes a quadrilateral section as shown in .Fig. 8. The hose is then dried, filled with water under pressure and emptied. It is then suspended vertically and filled with a rubbercontaining liquid. Upon emptying the hose, it is left in the same position to dry and set the layer of rubber adhering to the inner surface. It may then be repeatedly refilled with rubber-containing liquid, emptied and dried to deposit further layers of rubber; four to six layers being specified. The term " tightening " is used as meaning rendering 'impervious to water and other liquids.

Title: Improvements in or relating to the production of insulated ferro-magnetic powder andof cores therefrom
IPC: F01D1/16
Filed: 1931-11-23
Abstract: A ferro-magnetic powder for the manufacture of cores for induction coils is made by adding a solution of alkaline reaction and small quantities of fat to iron powder to effect insulation thereof by a substance having a fatty basis when subsequently dried.  The alkaline solution may be potassium silicate or hydrate, or sodium biborate or hydroxide, borax or water glass, or solutions of sodium chloride, magnesium chloride, or organic substances such as sugar or gum arabic &c., with quantities of alkali, and when insulating substances insoluble in water, e.g. shellac, are used a solution thereof in alcohol, to which alkaline additions are made, is employed.  Oils such as linseed, rape, olive oils, and the like, even when rancid, are employed as the fat and sufficient alkaline solution is added to produce complete saponification thereof.  Solid constituents such as fine fibre particles of wood pulp, silk, asbestos or the like may also be added to the insulating medium.  The fat or oil may be added to the alkaline reacting insulating medium and then mixed with the magnetic powder, or the powder may first be slightly fatted and then mixed with the alkaline liquid.  In an example, 100 kg. of iron powder is mixed with 30 gm. of olive oil.  500 gm. of borax is dissolved in 10-15 litres of water and 500 gm. of fine asbestos fibre particles added to the solution which is then intimately mixed with the prepared iron powder.  The resulting paste is dried by heat to produce a powder which may be compacted into cores.
