Patent GB-319076-A (GB)
Title: Improvements in or relating to gramophone reproducers
IPC: H04R11/08
Filed: 1928-06-19
Abstract: 319,076. Miller, J. P. June 19, 1928. Gramophone pick-ups; magnetic instruments. -The vibrating armature of a gramophone pickup is damped by a pair of resilient tubes of different length bearing on the end of the armature remote from the actuating stylus, means being provided for adjustably compressing said tubes. The substantially J-shaped permanent magnet 1, Figs. 2 and 4, carries on its shorter limb a U- shaped pole-piece 3, the distance between the limbs of which may be adjusted by a screw 4, and which carry coils 5 and 6. The armature 7 is pivoted on adjustable bearings 9 attached to a member 10, bolted to the longer limb of the permanent magnet 1. The member 10 carries a short brass or other tube 13 fixed into a hole coaxial with the armature, the space between the tube and the armature being occupied by a rubber tube or tubes 14. The pressure exerted by the rubber may be rendered asymmetric either by indenting the tube 13 as at 13a, by driving a pin into the rubber in the same direction, or by any other means. This " bias " is taken up by adjusting the armature bearing, thus ensuring the proper adjustment of the latter. A cross bar 8a integral with the armature is located between and extends towards the limbs of the pole-piece 3, and attached to the upper end of the armature, which at its lower end has a stylus holder 8, is a brass or other plate 15, through which passes, with a good clearance a bolt 16, fixed to a plate 17 enclosing the mechanism. On either side of the member 15 and threaded on the bolt 16 are resilient tubes 19, 20 adjustable by nuts and washers 21, 22, also carried by the bolt 16. Another construction, Figs. 5 and 6 (not shown), differs from that described, in that the pole piece 3 and member 8a are located on the side of the pivot remote from the damping tubes 19, 20. A diaphragm may be mounted upon or driven by the vibrating armature for emitting sound.

Patent GB-467301-A (GB)
Title: Improvements in yarn or thread winding frames
IPC: B65H67/048
Filed: 1936-07-01
Abstract: 467,301. Winding yarns &c. SCHARERNUSSBAUMER & CO. July 1, 1936, Nos. 18252 and 18253. Convention dates, Dec. 17, 1935 and May 28, 1936. [Class 120 (ii)] In a winding frame having several winding spindles mounted in a carrier, which, at the termination of a winding operation, is automatically rotated for the purpose of bringing an empty bobbin into the working position. The carrier is also displaced longitudinally for the building of the cop and returned to its initial position when the carrier is rotated ; the step-by-step longitudinal displacement of the carrier may be controlled by a feeler co-operating with the thread of the cop being wound and at the termination of a winding operation the carrier leaves an abutment and permits the rotation of the carrier. As shown in the Figure, a pair of spindles 1, 1<1> are mounted between a pair of plates 2, 3 forming a carriage slidable on a hollow shaft 8 supported in the machine frame 9. The spindle 1 is driven by a belt 7, which preferably serves a number of frames, and the carriage and spindles are advanced step-by-step, as the yarn is laid on the bobbin 5 by a reciprocating thread guide, through the agency of the thread feeler 16 which, at each reciprocation of the thread guide, contacts with the yarn 15 and is rocked to turn a shaft 17 against the action of a spring ; the shaft 17 carries a contact arm 18 which closes a circuit through a motor geared to a screwed spindle 12 engaging a half nut 11 pivoted to an arm 10 on the carriage which is thus moved longitudinally against the action of a spring 19. The pivoted half nut 11 is held in engagement with the spindle 12 against the action of a spring by tail 2<1> on the plate 2 until the bobbin on the spindle 1 is completed when a tail 3<1> on the plate 3 moves part of the end of a bar 13 adjustably mounted on the frame ; the action of the belt 7 on the spindle 1 then rotates the carriage slightly and disengages the tail 2<1> from the half nut 11 which is disengaged from the spindle 12 by its spring. The spring 19 then restores the carriage to the initial winding position and during this movement a sleeve 20, having a helical groove 20<11> engaging a roller 8<1> on the shaft 8, is rotated and; by the engagement of a dog 20<1> at one end with a dog 2<111> on the frame 2, rotates the carriage to move the spindle 1 and the completed bobbin thereon to the doffing position and simultaneously bring the spindle 2 and empty bobbin 5<1> into the winding position with the tails 2<11>, 3<11> of the plates 2, 3 co-operating with the half nut 11 and bar 13 respectively. In a modification, the sleeve 20 and associated parts are dispensed with and the plate 2 is formed with a pulley-like extension which is grooved for the accommodation of the spindles 1, 1<1> which, when the carriage is returned to the initial winding position, engages the driving belt and is rotated thereby to move spindle 1 to the doffing position and the spindle 1<1> into the winding position.

Title: Improvements in or relating to rotary wet classifiers
IPC: B03B5/56
Filed: 1932-06-28
Abstract: 389,338. Washing granular materials. HARDINGE, H., Country Club Road, York, Pennsylvania, U.S.A. June 28, 1932, No. 18266. [Class 82 (ii).] Material to be classified is supplied with water to the inner of two rotary coaxially disposed drums, the fines being discharged directly from the inner drum while the coarser particles pass into the space between the drums for further classification. The apparatus comprises a main outer imperforate drum 10, Fig. 1, and an inner drum 11, the drums being mounted on rollers 57, 58 driven through gearing 62 by a motor 61. The material and water are introduced by a shoot 13 to the inner drum 11, and the light particles which float are carried by the flow of water out of an adjustable discharge aperture 17, the drums being preferably slightly inclined in this direction. The coarser particles sink in the drum 11 and pass through apertures 19 controlled by plates 20 into the space between the drums 10, 11, along which they are moved by flights 12 attached to the inner surface of the drum 10, preferably against a stream of water introduced through a pipe 21. The water washes off any fine particles which are carried upwards through the apertures 19 into the drum 11 and out of the discharge aperture 17, the size of the particles discharged through the aperture 17 being determined by the size of the adjustable apertures 19, the speed of rotation of the drums, and the quantity of water introduced. The coarse particles are discharged by buckets which raise the particles, allow water to drain off, and discharge the particles into a hopper 29. Various forms of buckets are described. The buckets mav be attached to the main drum and in one form, Fig. 6, an annular screen 34 is attached to the end wall of the drum 10, which forms one side of the buckets, individual plates 36 form the other sides of the buckets and adjustable pivoted vanes 33 constitute the bottoms of the buckets. In the form shown in Fig. 1, the buckets are attached to a wheel 25 so that the buckets and the drums may be driven at different speeds, the bottom of the buckets being formed by an annular screen 30. In another form, Fig. 8, in which the buckets are mounted on a wheel, the buckets having bottom plates 40 and side walls 41 are pivotally mounted on the wheel and the water drains away in the adjustable space between the buckets and the side wall 43 of the drum. The hopper 29 which receives the particles discharged from the buckets may, as shown in Fig. 6, be provided with an adjustable lip 37, and may discharge into an elevating wheel 53, Fig. 1, which in turn discharges into a shoot 54 leading to a mill in which the coarse particles are re-ground. In the form shown in Fig. 9 the drums are conical and the coarse particles sink in the space 49 and pass through adjustable apertures 50 into the space between the drums.

Title: Production of images for photo-mechanical peproduction
IPC: G03F1/92
Filed: 1948-07-07
Abstract: 656,795. Producing record of printing forme on light-sensitive material. BAXTER, H. R. July 7, 1948, No. 18271. [Class 98 (ii)] A method of obtaining a record from a printing forme comprises inking the forme with an opaque ink resistant to photographic processing solutions, transferring an ink impression of the forme to the image-forming side of a photographic material, processing said material image-wise by virtue of the resistance of said ink impression to processing solutions, removing the ink impression after said processing, and exposing the photographic material to uniform illumination at least prior to the ink printing stage, while it may be exposed to light throughout the whole process. Thus the photographic material, which preferably has a silver halide emulsion, carrying the ink print may be developed with a contrasty developer followed by passage through a stop bath prior to the removal of the ink and then fixed to produce a negative, or may be fixed with hypo prior to said ink removal and then developed to yield a positive. The photographic material may be a contrasty bromide paper and the ink may be a greasy ink and may be removed by a solvent such as acetone or carbon tetrachloride. The record so produced may be used in producing further printing formes photo-mechanically.

Title: An improved method of, and means for, handling biscuits
Inventor: PAGE ALFRED CORNELIUS
IPC: A21C15/00
Filed: 1951-08-02
Abstract: 695,423. Shoots and hoppers. WRIGHTS BISCUITS, Ltd. April 1, 1952. [Aug. 2, 1951] No. 18308/51, Class 78 (i). The discharge of biscuits from a vertical hopper is prevented until such time as there is a pre-determined number of biscuits above the lower end of the hopper by means of a pair of side plates 17 within the hopper. The plates 17 are lightly urged towards each other so as to grip the edges of the biscuits, the normal spacing between the lower ends 17a of the plates 17 being less than the spacing between the upper ends and less than the width of the biscuits so that no discharge occurs until the weight of the biscuits is sufficient to overcome the force urging the plates towards one another. As shown, the plates 17 are mounted on parallel links 18 and are urged inwardly by adjustable weights 21 carried on arms 20 controlling these links. Alternatively, the weights 21 may be replaced by springs. The hopper may be used in conjunction with the biscuit feeding apparatus described and claimed in Specification 670,590.

Title: Diffusion method
IPC: C30B31/16
Filed: 1966-04-26
Abstract: 1,136,304. Semi-conductor devices. RADIO CORPORATION OF AMERICA. 26 April, 1966 [10 May, 1965], No. 18134/66. Heading H1K. An impurity is diffused into a wafer of semiconductor material from a source comprising a wafer of a nitride of the impurity element having a surface layer of an oxide of the impurity element. The semi-conductor and source wafers are placed close together with their major faces parallel, and are heated to a temperature at which the oxide vaporizes and the impurity element diffuses into the semiconductor wafer. A plurality of wafers may be simultaneously diffused in the apparatus of Fig. 1 (not shown), which comprises an electrically heated furnace tube (16) open at one end, the other end being closed and having oxygen and inert gas inlet tubes (24, 26). A plurality of wafers (42) of boron nitride are placed in alternate slots (42a) in a V-shaped quartz boat (44) and heated in a stream of oxygen to produce surface layers (48) of boron oxide. A pair of silicon wafers (14), placed back-to-back, are inserted in each of the slots (14a) between the boron nitride wafers (42) and the assembly heated in a stream of inert gas to vaporize the boron oxide and produce P-type surface layers (12, Fig. 1b in the silicon wafers. The diffusion depth may be increased by removing the boron nitride wafers and reheating the silicon wafers. Traces of oxygen in the inert gas and exposure to the atmosphere when the silicon wafers are removed ensure that the surfaces of the boron nitride wafers remain oxidized. The inert gas may be argon, nitrogen, helium, or forming gas. The impurity sources may also comprise surface-oxidized wafers of gallium nitride, indium nitride or aluminium nitride and may be produced by compacting powdered material. Boron nitride wafers may also be oxidized by boiling in sodium hydroxide, by washing in hot water, or by heating in steam. The invention may also be applied to germanium wafers but the diffusion temperature used must be below its melting-point.

Abstract: 563,185. Luminescent materials. SIEMENS ELECTRIC LAMPS & SUPPLIES, Ltd., and AUSTIN, H. Dec. 28, 1942, No. 18404. [Class 39 (i)] [Also in Group III] Luminescent magnesium tungstate is manufactured by precipitation by reaction between reagents in solution, drying the precipitate and heat treating the dried precipitate in the presence of a flux to a point where it begins to Sinter. In an example, a boiling saturated solution of sodium tungstate is added to a boiling saturated solution of magnesium cliloride, and the precipitate is filtered off and dried at a temperature of 110‹ C. in a current of dry air. An excess of magnesium chloride is present so that free chloride is present in the precipitate and acts as the flux. The powder is then heated in a furnace to 850‹ C. or 900‹ C. until it commences to sinter. After this the powder may be given a further heat treatment for one hour at 1,000‹ C. after the flux has been washed out.
