Title: Improvements relating to the production of sound records
IPC: G11B23/00
Filed: 1936-04-24
Abstract: 473,988. Gramophone records. NEUMANN, F., and DENGLER, A. April 24, 1936, No. 11744. [Class 40 (ii)] Relates to laminated disc records comprising sheets a carrying sound-track layers b on their outer surfaces, which sheets are pressed together with the interposition of a mass of stiffening binding material e, whilst sound-grooves are impressed in the layers b. According to the invention, during the pressing process the mass e is forced outwardly, and by the use of suitable dies or tools in the press it forms a peripheral rim f completely enclosing the edges of the layers so as to protect them and prevent the penetration of moisture. The rim f may be so formed as to project materially above the surfaces of the layers b. The stiffening mass e may be made of a shellac-like composition, and may have a reinforcing layer g embedded in it. Paper (on which pictures may be printed), fabric, metal foil or the like may be used for the carrier sheets a, and the soundtrack layers may consist of cellulose or resin lacquer, or the like.

[Classes 83 (ii) and 83 (iv)] Shearing.-A bale tie is made by drawing a wire through straightening rolls by a chaintraversed hook, bending one end U-shape and then closing the loop between guiding rolls, twisting the loop by rotating the hook and severing to length. Straightening.-The straightening-rolls 15 are mounted on a sprung plate 16 pulled into the feed path by the wire-tension after forming the loop, and freed when the wire is cut to swing the stub W across the feed-path prior to the next engagement. The hook 1 is mounted on a carriage 3 chain-traversed and steadied during looping and twisting by rollers 4 and guides 5. Twisting wires together.-An Archimedian spiral on the hook shaft 32 is rotated for twisting when a sprung ball nut 35 engages sprung abutments 41. A telescopic spring device is linkconnected to the abutments 41, Figs. 13-16, not shown, to counter inertia shock, and has a ball lock to release the abutments when the nut spring 40 is fully compressed Angular bending.-The bending-roll 18, 19 are grooved to receive the wire and are mounted on spring-urged plates 20, 21 pivoted to swing in the feed plane. The roll 19 is spring- depressed and is raised into the feed plane during looping etc., by a lever, Fig. 1, not shown, engaged by the carriage 3. Shearing.-A flying shear is mounted on the chain 9 and comprises horizontally movable, apertured cutters C toggle-operated when arms 75 engage ramps 77 fixed to the guides 5. Operation. The wire W, swung over the roll 19 by the plate 16 is hooked and drawn through the rolls 18, 19, U-bent and looped. The nut 35 strikes the abutment 41 and the hook 1 is rotated to twist the wire. The required length is drawn through the rollers 15 swung into line, and sheared by the cutters C and the tie is detached from the hook 1. The latch holding the hook spring 40 is released and resets the hook 1. In a modification the traverse speed is increased after twisting. In a further modification the loop is detached from the hook 1 after twisting and the wire is fed through powerdriven rolls. In further modifications the cutters are fixed and the hook may be reciprocated or mounted on a wheel.

Title: Improvements in or relating to fastener-inserting means
IPC: A43D71/02
Filed: 1935-04-17
Abstract: 455,296. Nailing. BRITISH UNITED SHOE MACHINERY CO., Ltd., and ROBERTS, W. T. B., Belgrave Road, Leicester. April 17, 1935, No. 11798. [Class 89 (iii)] The driver passage 6 of a mechanism for inserting headed fasteners, particularly for incorporation in toe-lasting machines, is formed with a recess in one wall, at which is located the straight lower end 10<1> of a leaf spring 10. Normally, the end 10<1> is inclined somewhat into the passage, so that it engages one side of the tack head and presses the other side against the fixed wall of the passage. The driver 8 is of less diameter than the tack head, or is reduced at its lower end. Thus, the spring centralizes the tack for a substantial part of its travel, at least until its point has penetrated the work. The lower end of the driver may be concave, or bevelled in one direction if the tack is to be driven at an inclination. Specifications 370,024 and 419,938 are referred to.

As shown FM and AM IF amplifiers 16 and 46 supply a rectifier 3 and a AM detector 5 which provide D.C. signals Sf and Sa representing the input signal strengths to a combining amplifier 6 and a meter drive circuit 30. A transistor 16 connected as a diode limits the signal across a meter 40 to protect it from high AM signal levels. Integrated circuit techniques can be used for the receiver and indicator circuits. In a modification Fig. 2 (not shown) the sensitivity of the meter (140) can be made different for FM and AM broadcasts by making the characteristics of first and second current sources (107 and 108), which receive the signals Sa and Sf, different. By making the emitter areas of (113 and 114) greater than (116 and 117) the sensitivity of the meter is higher for AM than FM reception.

Title: Method of testing terephthalic acid to be converted into polyethylene terephthalate
IPC: C08G63/183
Filed: 1962-04-03
Abstract: A batch of terephthalic acid is tested to determine its suitability for conversion into polyethylene terephthalate by measuring the light transmittance of a solution of a small portion of the batch and rejecting the batch if its light transmittance does not correspond to a transmittance of 90.98%.  The light transmittance method comprises dissolving 7.5 grams of the acid in 50 ml. of aqueous 2N potassium hydroxide solution, measuring the light transmittance of the solution in a spectrophotometer using a wavelength of 340 mm  and a cell of length 10 mm. ml. comparing the transmittance with that of an aqueous solution of 2N potassium hydroxide as standard.  Terephthalic acid of the desired purity may be made by treating an aqueous solution of the potassium or ammonium salt of the acid with potassium permanganate and active carbon and precipitating the acid from the solution (see Division C2). The purified terephthalic acid may then be converted into polyethylene terephthalate by heating the acid with ethylene glycol under atmospheric or superatmospheric pressure and polymerizing the resulting product.  Specification 747,204 is referred to.ALSO:A batch of terephthalic acid is tested to determine its purity by dissolving 7.5 grms. of the batch in 50 ml. of 2N aqueous potassium hydroxide solution, and comparing its light transmittance with that of a 2N potassium hydroxide aqueous solution at standard; the measurement being made with a spectophotometer using a wave length of 340 m m  and a cell of length 10 mm.  If the transmittance is 90-98%, the batch is converted into polyethylene terephthalate (see Division C3).  In example, purification to the desired light transmittance is effected as follows (1) potassium terephthalate prepared from potassium phthalate by the process of Example 1 of Specification 747,204 is dissolved in water and the solution, after filtration, is treated with potassium permanaganate and active carbon whereupon the resulting solution, again after filtration, is acidified to liberate the terephthalic acid which is agitated with water and then dried; (2) crude terephthalic acid prepared from p-xylene by the CRC process is dissolved in aqueous ammonium hydroxide and the solution treated with potassium permanganate and active carbon; the solution is then centrifuged to give wet terephthalic acid which is heated in an autoclave with aqueous sodium hydroxide solution, the solution allowed to cool, and the purified terephthalic acid precipitated by the addition of hydrochloric acid.
