Title: Improvements in machines for space winding wire wound potentiometers and like instruments
Inventor: LAWS ARTHUR ERNEST
IPC: H01C17/04
Filed: 1957-11-14
Abstract: 857,297. Coiling. DE HAVILLAND PROPELLERS Ltd. Feb. 16, 1959 [Nov. 14, 1957], No. 5335/59. Divided out of 857,296. Class 83 (4). A machine for winding wire wound potentiometers comprises a lead screw, a block of comparatively soft material engaging the threads of the lead screw and movable axially of thereof as a result of rotation of the lead screw, means for supporting a former, which is to be wound, in driven connection with the lead screw, and a second block of comparatively soft material connected with the first block and being adapted to engage the wire turns as they are laid on the former and correct any errors in the wire turns already laid. A former 9 to be wound with wire from a bobbin 19 is mounted coaxially, and rotated by engagement, with a shaft 4, driven by a belt 7 and formed with a lead screw 5. The first few wire turns are wound on the former 9 by means under control of the lead screw 5. Thereafter, a block 39 of soft material such as red fibre or polytetrafluorethylene, having a V notch for guiding the wire to the former, is pressed against the wound turns by a spring 40, Fig. 3. The block 39 is carried by an arm 38, swingable about a rod 14, parallel with the shaft 4 and axially fixed relative to the rod 14, together with a guide pulley 18. Thus axial movement of the rod 14, under control of blocks 28, 29 of soft material engaging the lead screw 5, causes the block 39 to transverse the former 9 to complete the winding, grooves being worn in the block 39 by engagement with the wound wire. The blocks 28, 29 are pressed against the lead screw 5 by springs 37 and are carried by links on an arm 24 fixed to the shaft 14 and guided by a roller 23 at its upper end running in a groove 22 so that the rod 14 cannot turn. The blocks 28, 29 are freed from the lead screw by rocking a lever 25, Fig. 4. The threads of the lead screw may be cleaned by a pad or brush associated with the blocks 28, 29 and burrs may be removed by a wooden lap loaded with rouge. The former may be cleaned prior to application of the wire by a pad or brush associated with the block 39. The lead screw may comprise wire, of one gauge larger than the wire to be wound on the former wound on a cylindrical mandrel and fine wire wound in the troughs. Formers of non- circular section may be wound.

Title: Refractory materials for use in converter linings
IPC: C21C5/44
Filed: 1961-02-14
Abstract: A refractory composition for use in converter linings consists of (a) coarse basic refractory material from the group consisting of dead-burned magnesite containing at least 55% of magnesium oxide and dead-burned dolomite the particles of which are coated with an unbroken layer of calcium ferrite, (b) fine magnesite, which has been burned at a temperature of at least 3000 DEG F., containing at least 55% magnesium oxide, and (c) 2 to 7% by weight of a bonding material, based on the total mix, from the group consisting of tar, pitch and asphalt, the particles of the coarse constituents being all less than 3/8 inch with at least 50% plus 10 mesh (Tyler), and the fine magnesite being at least 80% minus 65 mesh (Tyler), the coarse fraction constituting 55% to 80% by weight of the mix.  The refractory composition may also contain up to 7% by weight of free carbon, based on the total mix, having a particle size not coarser than 100 Tyler mesh and added in the form of naturally occurring graphite, manufactured graphite, coke, carbon black or pitch.  Bricks of the refractory composition are produced by blending together the refractory aggregate and the bonding agent at a temperature of 200 DEG F. above the softening point of the particular bonding agent used and thereafter pressing the batch at a temperature such that the mix will flow into the mould and give maximum density on forming.

Abstract: 1,151,673. Quinone. INSTYTUT PRZEMYSLU ORGANICZNEGO. 2 Feb., 1968 [4 Feb., 1967; 24 June, 1967], No. 5535/68. Heading C2C. In the manufacture of quinone by oxidizing aniline with manganese dioxide, the excess manganese dioxide in the reaction product is reduced to water-soluble manganous salts before the quinone is separated from the reaction mixture. Specified reducing agents are hydrogen peroxide, nitrites and alkali-metal sulphites, bisulphites and hyposulphites. The quinone may then be separated by steam distillation. Alternatively, the quinone may be partly reduced to form quinhydrone, or sufficient hydroquinone may be added to form quinhydrone which, in either event, is then separated from the reaction mixture and finally reduced to hydroquinone.

Patent GB-452780-A (GB)
Title: Improvements in and relating to the reproduction of sound records
IPC: G11B7/00
Filed: 1935-02-27
Abstract: 452,780. Optical sound-reproducing apparatus. ZIEGLER, C., 74, Rue de Raynouard, Paris. Feb. 27, 1935, No. 6321. Convention date, Oct. 13, 1934. [Class 40 (ii)] [See also Group XX] Apparatus for reproducing sound from a film record having a number of parallel tracks thereon, preferably recorded in opposite directions, comprises means for winding the film from one reel to another, a source of light, a photoelectric cell, and means for displacing the record so that each of its tracks can pass in turn between the light source and the cell. Preferably the film is guided by pulleys, one of which serves as the means for displacing the record. In the apparatus shown, a very narrow film record F having two parallel tracks is used, the film passing between two reels 28, 28<a>, and being guided by pulleys or rollers 17, 18, 17<a>, 14 so that the sound track moves horizontally through a beam of light passing from a lamp 19 to a photoelectric cell 21. For displacing the film upwards or downwards so that either sound track can be scanned, the pulley 18 is movable vertically, being held in either of the two required positions by a ballcatch or similar stop. The pulley 14, serving for tensioning the film, is on a spring-controlled arm 15 which can be swung into and out of operative position. The feed reel 28 from which the record is unwound is supported on a part 4 pressed out from a partition plate 3, the reel being mounted on a tapered spindle 5 supported by a spring 6. The take-up reel 28<a> is supported on a disc 7 having a central spindle 8 which is driven by a motor 9 controlled by a flywheel. If two contiguous sound-tracks are recorded in opposite directions, provision is made for reversing the direction of rotation of the reels, automatically or otherwise. Each reel is formed of two cheeks connected together e.g. by riveting, one of the cheeks having a pair of elastic tongues 30, adapted to receive a small plate 29 bearing the title of the record. The plate 29 serves also to fix the free end of the film on the take-up reel. A reel cannot be placed on the spindle 5 without removing the title-plate 29, and the necessity for then applying the plate to the take-up reel prevents the plate from being mislaid. The filament of the exciter lamp (not shown) in the soundreproducing device has a high calorific inertia, so that alternating current can be used without producing humming. The lamp is in a casing covered by louvres 23. A cap covering the casing of the photoelectric cell 21 has a slit through which the light beam passes, and by rotation of the cap the sound volume can be controlled. The whole apparatus is in a cabinet with partitions 3, 3<1> and a lid 2. The lower compartment contains the motor and the amplifier, a loud-speaker being fixed to a vertical panel.
