Title: Improvements in or relating to gramophones
IPC: G11B19/265
Filed: 1930-05-23
Abstract: 351,688. Gramophones and sound recorders. OTTEN, W., 42, Teckstrasse, Ostheim, Stuttgart, Germany. May 23, 1930, No. 15960. Convention date, May 25, 1929. [Class 40 (ii).] Constant linear speed of the grooves of a disc record is obtained by a friction-roller driving mechanism which consists of two oppositely situated uniformly rotating friction rollers acting upon the record and turntable, respectively. A guide needle maintained at a constant distance from the rollers moves in guide spirals on the underside of the turntable. A motor 1 drives shafts 5, 5a to rotate friction rollers 6, 6a in opposite directions. The shafts 5, 5a are mounted in bushes 7, 7a which by means of guide-plates 8, 8a may be pressed towards one another by springs 9, 9a. The pressure of the springs, which rest upon pins 12, 12a movable in the stationary slotted guides 10, 10a and in the movable slotted guides 11, 11a, may be varied by moving the adjusting knob 13 which through the fork 14 slides the guide-bars 15, 15a in grooves 16, 16a. A guide needle 19 is spring-supported in a cylinder 18, which is connected to the guide-plate 8 through a branch piece 17. The turntable 20 and record 21 are free to slide longitudinally by means of the sliding carriage 23, guide-bars 24, and ball-bearings 25. In operation, the knob 13 is adjusted to press the rollers 6, 6a against the turntable and record, respectively, and the guide needle 19 engages in the guide spirals 27. When the driving motor 1 is started, the record and turntable are set in uniform rotary motion and slide with the carriage 23 towards the roller drive mechanism. Alternatively, two coaxial turntables may be employed, one of which carries the record while the other serves as the driving disc and may be provided on both sides with guide spirals. Instead of making the turntable slidable, it may rotate about a fixed axis and the rollers and guide needle or needles be made movable, the driving motor being either movable or, if stationary, coupled to the rollers by extensible shafting.

Title: Improvements in and relating to electric motor control
IPC: H02P5/68
Filed: 1927-06-16
Abstract: 274,437. British Thomson-Houston Co., Ltd., (Assignees of Weber, L. J.). July 15, 1926, [Convention date]. Actuating by electric power.-To obtain reciprocating motion of pumps or other machinery, a motor 10, which in the example described is an alternating current motor, is reversed automatically at the end of each rise and fall of the pump-plunder 11 in consequence of the increase of current in a series-wound relay 30 controlling a change-over relay 28 which alternately energizes the magnets of the motor reversing contactors 20, 21. Retarded auxiliary contacts 22, 23 temporarily keep the windings of the change-over relay open-circuited for a sufficient period after closing either of the motor switches, in order to give the starting current time to subside. At the limits of the reciprocating motion cushioning springs 16, 17 come into action in order to stall the motor gradually. Thermal overload protective devices of known kind are included in the motor circuit. The motor 10 may drive the plunger 11 through a screwed shaft. Specifications 209,436 and 215,384, [both in Class 38 (v), Electric switches &c.], are referred to.
Patent GB-160703-A (GB)
Abstract: 160,703. O'Dell, A. E., (Aktiebolaget Original-Odhner). June 26, 1920. Calculating-apparatus; full - stroke mechanism.-Relates to full-stroke mecha nism for manually operated machines which require a com plete revolution of a handle for their actuation, and consists in a notched disc on the main shaft co-operating with a ball held centrally by springs in a ball-race to form a one-way clutch. In one embodiment the invention is shown applied to a cam-disc and pin-wheel machine. On the handle shaft 1 is mounted a disc 2 with a notch 3 in its periphery, which co-operates with a ball 5 held centrally in an horizontal ball-race 4 by springs 7, 8, in such a way that on revolution of the handle in either direction the ball is moved from its central position by the edge of the notch 3, the ball preventing reversal of motion of the shaft 1 till the end of the revolution. The ball is put into an inoperative position by a screw 11 or an adjustable portion in the ball-race. Modifications are described in which (1) the springs 7, 8, are dispensed with and the ball-race is circular; (2) as applied to the cam-disc and pin-wheel machine the notch 3 is extended so that the ball acts only when the pins actuate the counting-mechanism. The ball can be replaced by rollers which can be slidably mounted in an oscillating arm.

Title: Improvements in the feeding of cartons and the like
Inventor: MASON JAMES ROLAND
IPC: B65B43/14
Filed: 1966-04-13
Abstract: 1,168,473. Feeding sheets. ROSE FORGROVE Ltd. 12 April, 1967 [13 April, 1966], No. 16092/66. Heading B8R. Collapsed cartons 11 supported on edge between side guides 12 and standing on a pair of laterally spaced endless chains 13 running on sprockets 14, are urged by chains 13 to a transfer position where the cartons are removed by suction device 19 against the restraining action of rollers 18 mounted on guides 12, and transferred to the feed conveyer of a cartoning machine. The advancement of chains 13 is effected by piston 26, Fig. 3, mounted in air cylinder 27, and connected to chains 13 by piston-rod 28, bearing 29 and sprocket 31 which engages with the chains. Compressed air is supplied to both sides of piston 26 by lines 36 and 42 such that the pressure at inlet port 38 is greater than at inlet port 41 causing piston 26 to urge sprocket 31 in a direction to tension the chains 13 and press the leading carton 11 against rollers 18. Upon removal of the leading carton finger 21 is tripped which opens bleed valve 24 and leaks air out of cylinder 27 causing a pressure drop on this side of the piston. Piston 26 is then urged outwards by the excess pressure on its other side, to drive the chains forward and bring the next successive carton against rollers 18, until finger 21 returns to its initial position and pressure again builds up on this side of the piston 26. The cycle is repeated until piston 26 reaches the end of its forward stroke whereupon three-port valve 39 is operated (manually or automatically) to seal off the pressure air and connect this side of the piston to the atmosphere, allowing the piston to retract to its initial position, the sprocket 31 freewheeling during such movement. Pressure regulating valves 37 and 43 are provided in lines 36 and 42 respectively.

Filed: 1952-06-27
Abstract: 742,056. Capacitors. BRITISH DIELECTRIC RESEARCH, Ltd. June 26, 1953 [June 27, 1952], No. 16296/52. Class 37. [Also in Group XV] Electrostatic capacitors are produced by a process involving the production of thin metal coatings of predetermined shape on the soluble surface of a non-metallic support by depositing metal on the soluble support surface by a thermal evaporation process, applying to those parts of the metallized soluble support surface from which the metal is to be removed a solvent for the soluble support surface and subjecting the metal deposit to a wiping operation to remove the metal from the parts of the support surface attacked by the solvent and leave the remainder adhering to the support surface. The solvent may be applied by printing with a patterned metal roller or by stencilling. The soluble support surface may. consist of (1) a cellulose nitrate coating on paper, and the solvent used to attack this soluble support surface after metallizing being ethyl acetate or a mixture of ethyl acetate and amyl acetate, or (2) an ethyl cellulose coating on polystyrene film, the attacking solvent in this case being ethyl alcohol or other suitable solvent for ethyl cellulose. The process may be applied to the production of metallized sheet or metallized films of insulating material in which areas of metallization are required to be spaced apart by non-metallized areas and alternate areas of metallization are required to be electrically connected in parallel by strips of metallization, so that by winding a length of such paper or film into a convolute roll a capacitor is obtained with two series of concentric electrodes.

Title: Photographic multilayer color film and masking process therefor
IPC: G03C7/18
Filed: 1950-06-30
Abstract: 701,039. Colour photography. GENERAL ANILINE & FILM CORPORATION. June 30, 1950 [July 16, 1949], No. 16405/50. Class 98(2) A multilayer material designed for integral colour-correcting masking procedure comprises superimposed red and green sensitive silver halide emulsion layers containing respectively cyan and magenta colour formers with a replaceable substituent in the coupling position, one or both of these layers containing also an additional similar colour former with no replaceable substituent; and a third, blue sensitive, emulsion layer containing an acylacetanilide colour former. In use the material, after normal exposure, processing and bleaching, is subjected to the action of a diazonium salt solution buffered to a pH below 6, to produce an azo dye printing mask in the cyan or magenta coloured layer or both by reaction with residual colour former which contains no replaceable substituent; no mask being formed in the blue sensitive layer by reason of the pH limitation. a-Hydroxy naphthoic acid amides may be used as colour formers in the red sensitive layer and pyrazolones in the green sensitive layer. Benzoylacetanilide colour formers for the blue sensitive layer yield satisfactory yellow images without masking. Extensive lists of these various colour formers are quoted. Diazotised aniline or numerous other amines as listed may be used as diazonium solution. Prior to treatment with this solution an aldehyde may be used to effect a controlled blocking of the coupling position of pyrazolone colour formers. In example 1 a material contains 3- [p-stearoylaminobenzoylacetamido]-isophthalic acid as yellow colour former in the blue sensitive top layer, a mixture of 1-(4<SP>1</SP> phenoxy-3'-sulphophenyl)-3-heptadecyl-5-pyrazolone and 1-phenyl-3-heptadecyl-5- pyrazolone-4-sulphoric acid as magenta colour former in the green sensitive layer and a mixture of 1-hydroxy-2-naphthoyl-N-octadecylamide-4-sulphonic acid and 1-hydroxy-2-naphthoyl-2<SP>1</SP>-N- methyloctadecylamino-5<SP>1</SP>-sulphoanilide as cyan colour former in the red sensitive layer, and this material is exposed, colour developed directly, further processed and treated with a diazotized sulphanilic acid solution buffered to pH 5, all solutions and treatment times being specified fully. Example II describes reversal procedure using the material and as far as applicable, the solutions of example 1. Example III and IV outline the aldehyde blocking procedure indicated above. Specifications 602,881, 652,953 and 665,657 are referred to.

Abstract: 1,147,757. Electrometer dosimeters. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. April 14, 1966 [April 15, 1965; Jan. 22, 1966], No. 16415/66. Heading G1Q. [Also in Division H1] A radiation dosimeter consists of two concentric cylinders 3, 12 and a fibre or like electrometer 5 connected to measure the potential difference between them. The two cylinders are of different materials and the dosimeter works on the principle that a potential difference is set up between them in consequence of the difference in electron yield of the two materials in the presence of ionizing radiation. The inner cylinder is a glass rod and the outer a metal tube, the glass having a lower average atomic number than the metal. The glass may be coated with a substance having an even lower atomic number, e.g. graphite, beryllium or titanium. The electrometer fibre is observed by an optical system whose axis is aligned with that of the glass rod, and to provide a compact construction the rod itself is part of the optical system. Thus in Fig. 2, 10 is a lens for viewing the fibre 5, the necessary light entering the opposite end of the casing and traversing the glass rod 3. Alternatively, as in Fig. 3 (not shown), a window (23) adjacent the fibre end of the dosimeter admits light to the casing and the optical system consists of an objective lens (31) bonded to or integrally ground on the adjacent end of the glass rod and an eye-piece lens (48) closing the other end of the casing.
