Title: Transducers
Inventor: SMITH ALBERT BERNARD
IPC: H04R23/00
Filed: 1963-10-03
Abstract: 1,058,208. Radiation gramophone pick-ups and microphones. A. BERNARD SMITH LABORATORIES Inc. Oct. 3, 1963, No.39055/63. Heading G1A. [Also in Division H4] A stereophonic pick-up comprises an incandescent lamp 1 (Fig. 1) moulded or embedded in a plastics light pipe 3, Fig. 4 (not shown), shaped to channel the light through slots 10 and across two mutually perpendicular vibrating shutter elements 4, Fig. 5 (not shown), of a stylus assembly 5. Each shutter element 4 is formed with a slit 4'. Light from lamp 1 proceeds through the slits 4' and falls upon photo-semi-conductor cells 7. Separate electrical signals are produced by the cells and are amplified. The stylus assembly 5 is secured by a weak spring or grommet 8. Grooves 11 in the light pipe 3 maintain proper alignment of the stylus assembly 5. A hole 17 renders the lamp 1 visible and aids cooling. The lamp 1 is energized by D. C., by rectified A. C. or by use of light chopped at a frequency of 200, 000 c/s. In the latter event the signal is demodulated before amplification, thereby avoiding errors due to thermal noise. Alternatively thermal noise may be eliminated by employing two identical photo-cells in push-pull, one in the dark and the other illuminated by lamp 1. White light, infrared radiation or beta- or gamma-rays may be utilized. Translucent transmitting or reflecting surfaces may be interposed between the light source and the cells to eliminate problems produced by filament vibration. In a second embodiment, Figs. 6, 7 (not shown), a neon tube is utilized and vanes (21) have edges (22) which determine the effective width of the beam impinging on the cells (7). The vanes (21) are not necessarily mutually perpendicular. The vanes (21) are mounted on a cantilever (31). The cells (7) may be silicon type solar cells, photodiodes or photo-transistors. A further embodiment has a vane (36), Fig. 11 (not shown), in the form of a flat V-notch and is secured to or integral with a nylon shaft (31). Photo-transistors (41), (42) are housed in independent light-tight boxes (44), (45) having windows (47). A cylinder (51), Figs. 12, 13 (not shown), has a coaxially mounted lamp (52) with photo-cells (54), (55) on each side. The cylinder (51) is formed with two diametrically opposite slits (57), (58) each having a light cut-off edge (59). The slopes of the slits (57), (58) follow opposite spirals. A gramophone stylus (6) may be secured to the lower edge of the cylinder (51) but is preferably mounted on an arm (61) secured to a shaft (62). The transducers of Figs. 6 to 11 may be modified to provide a stereophonic microphone by arranging the shaft (31) vertical. Fig. 14 (not shown), and connecting struts to mutually perpendicular diaphragms.

Title: A process for the manufacture of unsaturated polyesters and copolymers thereof
IPC: C08G63/54
Filed: 1956-12-21
Abstract: Unsaturated polyesters, copolymerizable with vinyl monomers to give resins of improved heat-resistance, bending strength, impact strength and shatter-proofness, are made by re-esterifying an alkyl ester of terephthalic acid or a substituted terephthalic acid (e.g. 2 : 5-dichloroterephthalic acid) with an aliphatic glycol to an extent of about 65-85% and at a temperature of about 120 DEG -200 DEG C., and thereafter adding an unsaturated dicarboxylic acid or anhydride and esterifying the remaining hydroxyl groups of the glycol at a higher temperature.  The glycol may be ethylene glycol, diethylene glycol, 1 : 3-butylene glycol, 1 : 2 butylene glycol, 1 : 3-propanediol or 1 : 4-butenediol.  Specified unsaturated dicarboxylic acids are fumaric, maleic, mesaconic, citraconic, itaconic and moconic acids.  As additional polyester forming reactants, there may be used saturated acids (e.g. adipic or phthalic acids) and tri- or higher poly-hydric alcohols (e.g. glycerol or pentaerythritol).  Reesterification may be effected in the presence of sodium methylate and the final esterification may be effected in the presence of xylene.  Specified vinyl monomers are styrene, vinyl acetate, vinyl crotonate and acrylonitrile.  In examples unsaturated polyesters were made from (1)-(4) Dimethyl terephthalate, ethylene glycol, diethylene glycol and fumaric acid or maleic anhydride; (5) Dimethyl terephthalate, 1 : 3- butylene glycol, diethylene glycol and maleic anhydride; (6) Dimethyl terephthalate, diethylene glycol, glycerol and maleic anhydride.  All of these polyesters were copolymerized with styrene in the presence of a peroxide catalyst and an accelerator.  The styrene was stabilized with hydroquinone or t-butyl pyrocatechol.

Abstract: 960,857. Machine tool details. M. FRANK. Nov. 9, 1961 [Nov. 9, 1960], No. 40234/61. Heading B3C. In a drilling or like machine tool, a control system for stopping or reversing the feed drive mechanism when a predetermined resistance is encountered is actuated by a stop, which when engaged by a moving part generates a reaction which adjusts the position of a control member against a constant bias, such adjustment being arranged to actuate the control system. A drilling spindle and sleeve 1, 2 are moved in the feeding direction A, and retracted by a rack and pinion 3, 4, the pinion being secured to a shaft 6 rotatable in a clockwise direction by a worm-wheel 7 or in a counter-clockwise direction by a worm-wheel 8. Worm-wheels 7, 8 are selectively connected to electromagnetic couplings 9, 10 by sleeves 11, 12 slidable on pins 8<SP>1</SP> and are driven by worms 13, 14 coupled by gears 17 which are driven by bevel wheel 18. Shaft 16 is mounted in a member 20 slidable against a spring 21 and when the drilling spindle is opposed by a high resistance the reaction is transmitted through shafts 6, 16 and member 20 is displaced axially to compress spring 21, thus actuating a switch 24 to stop the feed or reverse the direction of the latter. The resistance may be due to a drill breakage or due to the drill reaching the desired depth in the work. In the latter case a stop 25 on spindle 1 engages a fixed stop 26, and relays 30, 31 are used in conjunction with a switch 32 to reverse the spindle movement at both ends of its travel. The spindle driving motor is connected to leads 35, the control system is fed off the mains through a transformer 36, and a rectifier 37 and switches 33, 38 are provided. Worm 13 may have a greater pitch than worm 14 to provide a quick feed return, and in a modification the electrical control system is replaced by an hydraulic or a pneumatic system.
