Title: Improvements relating to the manufacture of flexible metal tubes
IPC: B21C37/12
Filed: 1933-11-20
Abstract: 428,937. Coiling. TONDEUR, R., 25, Denbigh Terrace, Notting Hill, and BOWDEN (ENGINEERS), Ltd., Victoria Road, Willesden Junction, both in London. Nov. 20, 1933, Nos. 32375/33 and 2021 /34. [Class 83 (iv)] In making flexible tubing of closely interwound open coils for Bowden mechanism as described in Specification 412,367, [Group XXIV], wires 47, 46 are wound through tangential holes in a die 7 by a mechanically operated chuck 10. A mandrel 8 passes through the die 7. The wound tube is gripped by the chuck 10 rotated from a shaft 11 and the wires are pulled simultaneously through the die to force one wire between the convolutions of the other. Resistance to the opening out of the leading coil is offered by the die 7 which moves backwards along a slide 18 against pressure of a spring 20. When a few coils have been formed the chuck is opened by a cam 14 and a cam 15 moves the die forward to feed the coils through the chuck. The chuck is then closed and the operation repeated. To start the machine, the end of one wire is bent and engaged by an apertured sleeve secured to the chuck to start the coiling and the second wire is then started. The sleeve is then removed and the coiling commenced. To place the wires under tension they are fed through spring-pressed wire guides 24, 25 which are angularly adjustable. The wires may be formed of triangular, trapezoidal or round section and are wound to allow of the tube being flexed without varying the axial length of the tube. The chuck may be provided with roller jaws to pull the formed tube continuously from the machine. Four or more even number of independent coils may be interwound.

Title: Method of and apparatus for the reception or transmission of electro-radiant energy
IPC: G01S3/08
Filed: 1919-12-24
Abstract: 138,318. Kolster, F. A. Jan. 30, 1919, [Convention date]. Directive wireless signalling; aerials and like radiating and receiving conductors.- An aerial system for directional propagation and reception consists of a rotatable coil A in series with a condenser C and connected to earth (or equivalent capacity area) through an inductance L. The closed circuit A, C by itself has a bi-directional characteristic, with a maximum in each direction in the plane of the coil A, but with the coil A also acting as a capacity area in the open circuit A, L, E the system gives a heart-shaped unidirectional characteristic, as shown in Fig. 2, with zero effect in one direction and a maximum in the opposite direction. The maximum and minimum directions can be reversed by a switch s, Fig. 1, which connects the inductance L to one side or other of the condenser C. The coil A is formed with its turns well separated, so that while it has large capacity with respect to earth it has negligible distributed capacity with respect to the closed circuit A, C. The middle point of the coil may be connected to an auxiliary capacity area B, which may be a wire grid, as shown in Fig. 1, or an elevated plate, as shown in Fig. 3, or an ordinary wire aerial. In the case of reception, a thermionic detector D, Fig. 1, may be connected by a switch e either across the inductance L, for non-directional or stand-by listening, or across the condenser C, for directional working. The circuits A, C and A, L, E are independently tuned to the desired wave-length. In the circuit shown in Fig. 3, the inductance L is connected to a point between condensers C1, C2 which are bridged in series across the condenser C. The means for varying the capacities C1, C2 are coupled so that one increases as the other diminishes, and the adjustment of these capacities serves in place of the switch s, Fig. 1, for reversing direction. Instead of being connected directly across the condenser C, the detector D may be inductively coupled with the inductance L and with an auxiliary inductance in circuit with the coil A, and a similar arrangement may be used for coupling an oscillation generator to the aerial system. The coil A may be replaced by two coils (in series or parallel) at right-angles to each other, one or both of these coils being rotatable. The Specification as open to inspection under Sect. 91 (3) (a) describes an arrangement comprising a toroidal coil, as shown in Fig. 6 (Cancelled), with movable connexions F, G to the condenser C. When the contacts F, G are adjusted to give maximum effect, the direction is in the line r at right-angles to the line t bisecting the angle F, G. This subject-matter does not appear in the Specification as accepted.

A disposable, screw-on, integral housing filter for the oil circuit of an I.C. engine comprises a combined anti-drain, non-return valve and by-pass valve 20 and an annular, pleated filter element 7 of resin-impregnated paper, which is internally supported by an externally grooved, plastics support tube 30 (Figs. 3 to 5, not shown). Oil normally flows from inlets 16, depressing flange 21 of the valve, inwards through element 7, along the grooves in tube 30, through apertures 32 in the end of the tube and out through outlet 11. When element 7 clogs or when the oil is cold, sufficient pressure is developed to depress tubular section 24 of the valve inwards, enabling oil to by-pass the element 7. The upper end of tube 30 is castellated, and flange 38 thereon carries lugs 39 to limit downward depression of flange 21, these features defining the by-pass channel to the outer face of section 24.
