Title: Improvements relating to the treatment of fibrous materials
IPC: D01C1/02
Filed: 1921-07-27
Abstract: 187,346. McGill, D., and Volos Manufacture, Ltd. Julv 27, 1921. No Patent granted (Sealing fee not paid). Fibres, crimping and curling.-In the treatment of fibrous material such as caeoa-nut fibre to produce a substitute for horsehair suitable for stuffing upholstery and the like, a bale of cocoanut fibre is passed into a tank a, containing warm or cold water, having a circulating pump b and screen f. The tightly compressed fibre breaks up, and, under the action of toothed wheels n and narrow bands l, is conveyed as a sheet or mat to a shelf p and compressed by rollers q. A doffer s having teeth t delivers small quantities of fibre to a series of air trunks v by which the fibre, is delivered, under the action of a fan 6, between a stationary disc x and a rotary disc z. The portions are thus balled or curled, and passed by suction to a chemical tank 9 wherein the curl is rendered permanent. The tank 9 consists of a steam-heated drum through which the material is circulated along pipes by a suction pump 14, Fig. 3, which finally delivers the fibre and liquid to an inclined grid 18 through which the liquid runs back along a pipe 20 to the tank 9 while the fibre passes to a drying chamber 23 heated by steam pipes 27. A pipe 21 and valve 22 in the circulation system of the tank 9 enables the flow to be reversed when the pump 14 becomes choked with fibre. The balling or curling may be ejected by two endless belts 32, 33, Fig. 7, travelling as shown, the upper belt having a transverse jogging movement. The material is fed between the belt by a blower. A teaser 56, Fig. 6, may be provided at the outlet to the drying chamber 23.

Filed: 1937-07-22
Abstract: 501,339. Electrical musical instruments. COMPTON ORGAN CO., Ltd., J., and BOURN, L. E. A. July 22, 1937, No. 20330. [Class 88 (ii)] In an electrical musical instrument in which individual partials of notes are produced, a plurality ot orders of partials have a rising or falling characteristic over the whole or a substantial part of the scale. The invention is described as applied to electrostatic instruments such as are described in Specifications 403,444 and 433,050, where each key controls a set of contacts, which contacts are connected to the appropriate ring electrodes providing the partials of the note and engage bus-bars energized under the control of stops. In Fig. 2, a ring 1 providing several co-pitch partials of different notes is connected to each appropriate contact 7 of a different note-key (which contacts 7 contact with different ones of the bus-bars 6 representing the orders of partials) through a respective resistance <@3>, and through a common potentiometer resistance l<2> connected to earth, and a common resistance l<1>. A single condenser c also connects the ring to earth, forming with the resistance l<1> a low-pass filter; this condenser and resistance may be omitted if a sudden attack is required, or another condenser may be shunted across potentiometer l<2>. By varying the resistances l<2>, r<3>, any partial of any note in the scale may be made of the required strength, lower orders of partials being given, for instance, a rising, middle partials a flat, and upper partials a falling characteristic. Any order of partials may be given a number of different characteristics by providing a busbar for each characteristic of the partial, under the control of stops, further contacts being provided, each with -its resistance r<3>, on each key. To prevent robbing when two contacts 7 pertaining to a ring 1 are simultaneously made, additional leak resistances a are inserted between the contacts and earth. In Fig. 3, the resistance a is cut out, and the resistance r<3> brought in, when the contact 7 connects the ring to the bus-bar. In Fig. 4 (not shown), the resistances a are dispensed with, the resistances r<3> being utilized instead when the contacts 7 are not operative. In Fig. 5 (not shown), the circuits are as in Fig. 2 without the resistances a, rectifiers being inserted between the resistances r<3>, l<2> to prevent robbing. Specifications 499,330 and (in the Provisional Specification) 453,846 also are referred to.

In a shut-off valve, such as a de-sludging valve, comprising two closure members B, C, Fig. 1, arranged in series in a pipe-line with the spindle H of valve B passing through the hollow spindle J of valve C and with a single loading or closing weight or spring F arranged outside the flow line and acting on both closure members, the spring, &c. acts on the spindles through a transmission mechanism, and an operating lever K also acts through the transmission mechanism to add an additional closing force on one or both members B, C. As shown, the spring F acts in compression between two levers K, L both pivoted to the valve casing, so that, when operating lever K is raised, valve B is closed due to the direct connection between its spindle and lever K and valve C will be closed due to the connection of its spindle with lever L. When lever K is lowered, valve B is opened directly and valve C is opened when an abutment collar P on spindle H contacts the top of spindle J. In a modification, the valves B, C, Fig. 2, open in opposite directions away from a single or double seat member c, and, in the closing direction, the spring F acts on a cam member R which it forces between levers K, L with a common pivot, the levers acting against abutments on the two valve spindles. The operating lever O carries an abutment O 2  which contacts spindle H to open valve B when the lever is depressed, and one arm of the lever is also connected to the cam R. The valve B can be forced to and held in the closed position by a screwed spindle Z. A device for continuously removing salt can be fitted to an attachment k. Four additional modified arrangements of cams, levers, &c. are described.
