Filed: 1929-02-14
Abstract: 329,300. Miller, J. W., and K.N. Electrical Products, Ltd., Feb. 14, 1929. No Patent granted (Sealing fee not paid). Magnetic instruments. - A sound recording or reproducing device has a reed 6 freely supported at one end and firmly connected to the free end of a rigid lever 9 arranged parallel to the reed; the lever 9 may be freely mounted on a rigid pivot as shown in Figs. 1. and 3, the connection 11 being flexible, or the lever 9 may be mounted on a flexible pivot, the connection 11 then being rigid. According to another aspect of the invention, the reed is controlled by a spring 11 adapted to flex in a direction substantially at right angles to the direction of movement of the reed. The spring 11 is rigidly attached at right angles to both reed and lever, and, on attraction of the reed by the pole pieces 5, flexes as shown in Fig. 3, providing a high progressive resistance to movement. A screw 13 provides adjustment of the gap between the reed 6 and the pole pieces 5 by moving the frame 2 on which the reed is mounted. The system also acts as a mechanical amplifier since the displacement of the point R is greater than the displacement of the point S by an amount due to the flexure of the spring 11.

Title: Apparatus for joining wires and the like by fusion
IPC: B23K11/31
Filed: 1944-03-20
Abstract: 572,324. Uniting by fusion. STANDARD TELEPHONES & CABLES, Ltd., and GILLIVER, G. March 20, 1944, No. 5136. [Class 83 (iv)] A hand tool for joining wires or strips by fusion, particularly for joining wires to terminal tags, comprises a handle in the form of a casing carrying a pair of spaced plates insulated from each other, between which is located adjacent one of them a spring-mounted carbon electrode movable towards and away from an aperture in the other plate, a trigger lever supported in the casing and carrying a clamping spring movable across the aperture, and means for connecting an electric circuit to the electrode and clamping spring. The handle casing is formed of two metal castings 1, 2, connected together by bolts and nuts 3, 4, 5, and carrying at one end side plates 6, 7, of which the plate 6 is insulated from the casing. Secured to the plate 7 is a spring 12 on which is slidably adjustable a carbon electrode 13 and adjacent a rhomboid-shaped aperture 8 in the plate 6 through which the wires are passed, is secured an anvil 9 against which the wires are clamped by a spring 10 secured by a contact stud 19 to a spring-returned trigger 11. The trigger pivot 16 carries a pawl 17 of insulating material which co-operates with a contact spring 18 connected to one lead from the cable 14 insulated from the casing, the other lead of which is secured by a circular clamping washer 32 between bosses on the two halves of the casing. To the side plates are welded shaped wire guides 24 to accommodate a window 15 to prevent splashes from the joint from reaching the operator. In operation, the wires to be welded, which are preferably twisted together, are pushed through the aperture in the plate 6 against the electrode 13 which is thus pressed back thereby until the spring 12 comes against the side plate 7. The trigger is then pressed so that first the wires are clamped by the spring 10 against the anvil 9 and then the pawl 17 releases the spring 18 which engages the contact 19 to complete the electric circuit through the spring 10, work and electrode 13. A bead is thus formed by fusion of the wires near the surface of the electrode and this automatically opens the circuit. Specification 560,500 is referred to.

[Classes 76 and 96] A spongy product resembling leather is obtained by preparing a suspension of swollen fibres of animal sinews, hide, or detanned leather in which a gas is diffused, allowing a shrinking agent to act and finally removing water and gas from the mass and tanning it. A swollen mixture of fibres e.g. of sinews and hides may be prepared in a homogenizing machine, gas being diffused in the mixture by any suitable method e.g. by adding a carbonate, if an acid swelling agent has been employed, or by " emulsifying " the mixture with air. If an acid swelling agent is used the shrinking may be effected by adding a neutralizing alkali, preferably in the gaseous or vaporous state e.g. ammonia or an amine. The process may be carried out in part while the mass is transported on a conveyer, e.g. a gas acting as shrinking agent may act on the material supported on a perforated belt, the extrusion of water being assisted by suction boxes. After shrinking, excess of diffused gas and water is removed, e.g. by a vacuum apparatus or press and by heating, the product being finally tanned in usual manner. Textile fibres may be mixed with the suspension of animal fibres. Specification 422,990 is referred to.

[Class 74 (ii).] Wrap thread plated effects are obtained in knitted fabrics by causing the wrap threads to flex the needles of a knitting-machine. To maintain one or more main yarns in plating relation with one or more additional wrap threads, tricks are removed or deepened in parts of the needle support. Wrap threads when fed under tension thus flex the respective needles so that the main yarn and the additional thread are positioned adjacent to the bill of the hook and adjacent to the shank respectively. The wrap threads 13 pass through eyes 12 in a rotary disc 11, driven by a shaft 10 connected by gearing 9, 8, 4, 3 to the ring gear 2 on which the needle cylinder 1 is mounted. The plain periphery of the stitch ring 20 is bevelled off at 21 and the needle tricks are cut correspondingly deeper at the top ends 22. In place of a conical stitch ring a cylindrical ring of smaller diameter may be used. Fig. 3 shows a needle deflected or pulled back against the ring 20 by the tension of the wrapping yarn but it may be deflected in other ways.
