Abstract: 295,686. Electrical Research Products, Inc., (Assignees of Schlenker, V. A.). Aug. 17, 1927, [Convention date]. Diaphragms; loud-speakers; magnetic instruments.-A diaphragm for sound radiators, more particularly of the direct-acting type, is provided with tapered lumped impedance elements distributed on its surface, the impedance elements and diaphragm constituting the elements of a low pass mechanical filter. In the construction, Fig. 2, a diaphragm 10, formed of a metallic alloy composed of approximately 98¢ per cent aluminium and 1¢ per cent manganese and of a thickness less than 0.005 inch, is maintained under high tension by a frame 11 and a clamping ring 12 secured to the frame by screws 13. Loading masses or impedances in the form of circular or square brass ,weights 30-42 are cemented or glued to the diaphragm as shown. In a modified construction, Fig. 4, the loading masses 40- 43 are spherical in cross-section and are preferably attached on both sides of the diaphragm 44, whilst in a further modification, Fig. 5, the loading is applied in the form of circular segmented rings 46-49 applied to one or both surfaces of the diaphragms 45. The diaphragm according to the invention is analogous to an electrical filter in that the masses of loading are comparable to the series inductance of the filter and the thin surfaces of the diaphragm are comparable to the shunt capacities. The diaphragm 10, Fig. 2, is driven by an electrodynamic unit 16 supported by cross-members on the frame 11, the coil 17 positioned between the annular magnet pole-faces 18, 19 being attached to the diaphragm so that its axis is offset from the centre thereof approximately two-tenths of the diameter of the inner radius of the loading masses. The frame 11 is attached to a baffle or partition 21 placed in a cabinet 22, protective screens 23 being positioned in the openings in the front and back of the cabinet.

Laminates comprising sheet material made of fibres, threads, or wires united by polyester resin adhesive, are made by first impregnating or coating the material with a solid, thermosetting, unsaturated polyester resin and a polymerization catalyst in the form of an organic peroxy compound, then wetting it with a liquid composition consisting of a stabilized polymerizable monomer containing the grouping CH 2 =C <, which is compatible with the polyester resin and a polymerisation promoter which coacts with the catalyst to induce polymerization of the monomer, and maintaining the wetted material in contact with other like wetted material or another wetted surface until the monomer has polymerized to form the desired bond. The sheet material may be fabric, paper, cardboard, wood veneer, wire gauze, or glass fibre mat. The polyester may be derived from a polyhydric alcohol such as glycerol, trimethylene glycol, ethylene or diethylene glycol, propylene glycol, pentaerythritol, 2: 2 - dimethylpropane - diol - 1: 3, 1: 3- butanediol, and 2 - butyl - 2 - ethyl - butanediol - 1 : 3, and an olefinically unsaturated dicarboxylic acid such as maleic, fumaric, citra-. conic, itaconic, mesaconic, aconitic, chloromaleic, and carbic acids. The monomer may be styrene, a methyl- or chloro-styrene, methyl acrylate or methacrylate, cyclohexyl acrylate, or vinyl acetate. The polymerization catalyst may be benzoyl peroxide, cyclohexanone peroxide, lauroyl peroxide, methyl ethyl ketone peroxide, t-butyl-hydroperoxide, cumene hydroperoxide, perphthalic acid, t-butyl-di-perphthalate, or t-butyl perbenzoate, and the promoter may be dimethyl aniline, dimethyl-p-toluidine, cerium, cobalt or manganese naphthenate, or dodecyl mercaptan. The stabilizer or inhibitor for the liquid monomer may be ascorbic acid, hydroquinone, or t-butyl catechol. The preliminary impregnation may be effected with a solution or suspension of the solid resin in a volatile solvent containing the polymerization catalyst, or by impregnation with powdered resin followed by a short heating to fuse the resin, with subsequent impregnation with the catalyst.

The Gray code read-out is converted to pure binary 57 (Fig. 2, not shown), stored in a shift register 58 from which a direct serial input 59 may be applied to the computer. Alternatively, in an error checking arrangement, the number is reconverted 61 to the Gray code and compared 63 with the succeeding stylus position whereafter if more than one bit position has changed a toggle 64 is set.

In one construction, Fig. 1, the wheel consists of two discs 18, 19 spaced apart at the centre and secured together at the periphery. The spacing-means may consist of two telescoped rings 21, with lugs bent inwards and outwards radially to form abutments for the discs. The rings may be carried by a wood filling-ring. The wheel is secured in position on a hub 15 by transverse bolts 16. In a modification, the disc 19 may be of less diameter than the disc 18. The support for the detachable rim may be formed by a ring 50 secured to the discs and carrying the studs 52 by which the usual clamping-plates 54 are attached. In a modification, the ring 50 may be formed by bending the disc edges transversely and a ring carrying the studs 52 may be secured in the angle so formed. Fig. 7 shows a further modification in which the disc edges are bent transversely, and the rim support 70 and the ring 71 carrying the studs 52 are secured together and to the discs by rivets. The support for the rim on the outer side of the wheel may be formed by a split ring 82, Fig. 3, the shape of which is adapted to the shape of the opposing surfaces of the rim and wheel.
