Title: Improvements in or relating to picture-projecting or exhibiting means working in conjunction with a track member constituting or moving in synchronism with a sound record
IPC: G03B31/02
Filed: 1924-04-14
Abstract: 239,564. Billing, N. Pemberton-, and World Record, Ltd. April 14, 1924. Combined phonographs and picture-displaying apparatus.-The subject of a gramophone or like record is illustrated by pictures which are brought successively into view by the movement of the stylus tracking the record or equivalent means engaging a track moving synchronously with the record, the stylus controlling the movement of shifting means which directly or indirectly operate or control the pictures. As shown, the pictureprojecting apparatus comprises a casing 13, Fig. 2, supported at one end on the turntable spindle and at the other on two adjustable diverging legs 55 secured to the casing cover 15 which carries telescopic members 57, 58 with a projector lens opposite a lamp 64 and reflector 65 arranged in the casing. The series of pictures 470, Fig. 5, are arranged in a circle on a disc 47, mounted by means of two unequally-positioned pins 49 on a flange 44 of a sleeve 41 carrying also a ratchet wheel 37. The picture disc is secured to the flange 44 by a disc 50, Fig. 6, with tongues 52 adapted to engage through corresponding slots in the picture disc and flange when the slots 51 in the securing disc 50 are applied over the pins 49. The successive pictures correspond to successive parts of the sound record, and are intermittently moved opposite a slot 61 in an adjustable plate 60 by means controlled by the stylus and comprising a two-part member 3, 7, Fig. 7, mounted on the turntable spindle and resting frictionally on the record so that a ratchet-toothed edge 4 thereon constantly bears against the stylus. As the stylus is traversed inwardly by the record groove it clears the teeth 4 successively, permitting successive small rotary movements of the members 3, 7 at each of which a serrated annulus 8 acts on a weighted pawl 33, Fig. 8, pivoted to an arm 32 on a shaft 16 to turn the shaft sufficiently to displace a spring-pressed flanged sleeve 19 with a face cam 21 clear of a stop-piece 30 and thus permit teeth 26 on the sleeve to be moved by the spring 23 into engagement with pins 27 on a rubber-tyred disc 28 sleeved on the shaft 16 and constantly driven by the record. The shaft thereby makes one complete rotation whereby the ratchet wheel 37 is driven, to position the next picture, by a tooth 36 on a collar 35, and the pawl 33 and arm 32 are brought to the position shown in Fig. 10 when the pawl falls into engagement with the serrations 8 again, the cam 21 having now disengaged the teeth 26 from the pins 27. In modifications, the pictures could be arranged on a band secured to the margin of the shifting means 7 and viewed by transmitted light, or the shifting means may control a relay which acts electrically, mechanically or otherwise to move the pictures projected by devices at a distance. Specifications 188,510 and 200,242 are referred to.

Abstract: 1521202 Superconductors BBC BROWN BOVERI & CO Ltd 10 March 1976 [12 March 1975] 09498/76 Heading C7D [Also in Divisions B3 and H1] A method of making a stabilized superconductor containing filaments of superconductive material in which a composite slug is mechanically deformed followed by the formation of superconductive filaments by the diffusion of at least one material from the outside of the conductor into a filament of second material inside the conductor, in which the parent slug contains rods or wires 2 of the second material which are surrounded by a material 3, 4, 5, 1, permitting the diffusible material to diffuse therethrough, and in its outer region rods or wires 6 of good electrical conductivity surrounded by a material 7 forming a barrier to the diffusible material, with, between barriers 7 a material 5 permitting the diffusible material to diffuse therethrough. Material 2 is Niobium, materials 1, 3, 4, 5, 6 copper, and material 7 is tantalum. In a second embodiment, Fig. 2 (not shown), a copper slug contains vanadium filaments, and outer copper rods surrounded by barriers of tantalum. The diffusible material is tin. The parent slug is closed at the ends and hot and cold deformed until a wire of e.g. 0À5 nm diameter is obtained, tinned, and the tin allowed to diffuse at 400C into copper 5, 4 and 3 and super-conductor compound Nb 3 Sn is subsequently produced at 700C by the diffusion of tin into the niobium filaments. Superconductors based on Va 3 Ga and V 3 Si can be produced in a similar way. Components 1, 3, 4, 5 and (8, Fig. 2) can be of a bronze alloy. Components 6, (10) can be of silver or aluminium. Rods 2, (9) can comprise copper or bronze rods containing a large number of niobium or vanadium rods. The diffusion-blocking barrier material may be of tantalum, niobium, vanadium or an alloy of these, and their action is based on the slowly proceeding reaction of these materials with the diffusible material and their thickness.

Title: Process for the continuous manufacture of rayon from viscose and rayon manufactured by such process
IPC: D01F2/06
Filed: 1949-04-07
Abstract: In the manufacture of rayon, films, &c. by a continuous process in which viscose is extruded from a spinning nozzle or slit into a spinning bath in which partial decomposition of the cellulose xanthate occurs, the further decomposition is carried out in two stages in which (1) the extruded material is treated with an aqueous solution of an inorganic acid and at least one inorganic salt in which the molar ratio of acid to the salt or salts is less than one until the xanthate ratio in the extruded material is less than about 0.02, and (2) after being freed from acid solution containing salt by washing with water the extruded material is treated with an aqueous solution of acid either containing no salt or in which the molar ratio of acid to salt is greater than one until the xanthate ratio in the product has fallen to below 0.003 and preferably to 0.002.  The extruded material is then desulphurized and bleached in known manner. The first stage after-treatment bath may contain 0.5-6 per cent by weight of H2SO4 and correspondingly 1-10 per cent Na2SO4 and may be at a temperature of 60-95 DEG  C.  The second stage after-treatment bath may contain 0.5-6 per cent by weight of H2SO4 and percentages of Na2SO4 to give a H2SO4 : Na2SO4 molar ratio of about 3 : 1, the bath temperature being 60-95 DEG  C. and preferably 80-95 DEG  C.  In the example, viscose is spun into a coagulating bath at 50 DEG  C. containing 8 per cent by weight sulphuric acid, 17 per cent sodium sulphate and 2 per cent zinc sulphate.  The filaments of freshly coagulated and partially undecomposed cellulose xanthate are drawn as a sheet from the spinning bath into an after treatment bath at 80 DEG C. prepared by diluting the spinning bath until its sulphuric acid content is 4 per cent or less.  The threads are then drawn through a bath of water at 50 DEG  C. and thereafter through three liquid baths at 80 DEG  C. containing 4 per cent by weight sulphuric acid and less than 1 per cent salts.  The desulphurization of the threads is then completed and followed by bleaching and oiling in the usual manner. The process increases the speed with which desulphurization and bleaching of the threads or films can be carried out.  Specifications 17503/02, [Class 2], 432,692, 467,500 and 570,159 are referred to. The Specification as open to inspection under Sect. 91, refers also to the completion of the decomposition of the residual xanthate in the extruded material by the use of oxidizing agents such as hydrogen peroxide, potassium persulphate, chloric or perchloric acid, sodium chlorite or hypochlorite, and sodium nitrite.  Solutions containing 0.5-2 per cent of sodium hypochlorite, to be used at room temperature, or 0.2-1 per cent of sodium chlorite, to be used at 10 DEG  C., are preferred.  This subject-matter does not appear in the Specification as accepted.
