Title: Improvements in or relating to the recording of sound with the aid of light
IPC: G11B7/00
Filed: 1930-06-04
Abstract: 356,248. Photographic sound-records. GRAMOPHONE CO., Ltd., Hayes, WHITAKER, A., Colne Mead, West Drayton, both in Middlesex, and BROWNE, C. 0., 3, Freeland Road, Ealing Common, London. June 4, 1930, No. 17324. [Class 40 (ii).] An optical film-sound record is produced which is in the form of a plurality of separate identical sound traces of varying width disposed upon the film contiguously and substantially without stagger, and adapted for reproduction with the aid of a single light slit. In one method of production, light from a source 1, Fig. 1, is focussed by a lens 2 upon an oscillograph mirror 3 and a grid 4 is interposed so that light falls upon the mirror 3 in a number of similar beams of rectangular section. A second grid 5 is inserted in the path of the reflected light so that when the mirror 3 is in its position of rest half the lengths of the apertures of the grid 5 are illuminated. A microscope objective 6 focuses the resultant images upon a moving sensitive film 7. The light beams are focussed down to the width of the apertures in the grid 5 by a cylindrical lens 9. When the mirror 3 is vibrated in accordance with the sounds to be recorded there is thus formed on the film 7 a plurality of sound traces of variable width arranged contiguously and without stagger, Fig. 5. In an alternative method, Fig. 2, a negative film 10 bearing a record in the form of a single sound trace is passed over a guide 11 and light from a source 12 passes through the film 10 and a plurality of slits 13, 14, 15 in a grid 16, and is focussed by a plurality of lenses 17, 18, 19 arranged, as shown in Fig. 3, upon a positive film 20. The film 20 moves with the same velocity as the negative film 10, to produce three similar sound-record traces.

Title: An improved device for cutting a continuous strip of elastomeric material
IPC: B26D7/26
Filed: 1957-05-31
Abstract: 814,351. Strip-cutting machines. UNITED STATES RUBBER CO. May 31, 1957 [Aug. 23, 1956], No. 17345/57. Class 87(2). Strip is cut from sheet material 4 on a roller 3 by a pair of circular cutters 35, the spacing between which is adjustable and which rotate on ball bearings 38 mounted in brackets 21 at the end of a rocker arm 8 to maintain the peripheries of the cutters in engagement with the roller 3. The roller bearings are mounted on screw threaded collars 31, 32 on a screw threaded shaft 27, the portions 29, 30 having right and left hand threads respectively. By turning the collars the spacing between the cutters 35 mounted on them is altered and they are fixed in their adjusted spacing by set-screws 33 which screw down on flats 34 on the shaft 27. The minimum spacing is fixed by stop collars 39 press-fitted on the shaft 29 and the maximum by the length of the threaded portions 29, 30. Visual indication of the spacing is given by fingers 48 pointing to the peripheries of the cutters and projecting from bars 46, 47 which are graduated in inches. These marker bars 46, 47 extend from an arm 23 which carries the shaft 27 at one end and at the other end has pivot pins 24 by which it is pivoted in the brackets 21 (which are in the form of eye-bolts screwed to the rocket 8), this pivotal mounting allowing the shaft 27 to rock and thus allowing the cutters 27 to bear equally on the sheet 4 even if there is misalignment. The parts are so proportioned that one revolution of the collars 31, 32 moves the cutters from one marked position to the next. A visual check is provided by V-grooves 40, 41 and 42 in the collars 31, 32, the stop collars 39 and the end of the arm 23, which are in line when the setting is correct. The cutters may be moved further back if necessary by transferring the eye-bolts from holes 20 to holes 22. The rocker arm 8 may be raised and lowered by a hand-lever 9. The strip, after being cut, passes over a brush and is wound on a reel for storage.

The blocks are separated by block positioning codes BE, the individual words being separated by word positioning codes B K , W E . The data may represent daily or monthly amounts sold at a number of shops, the words A, B, C, D representing the data, shop, commodity, and the amount sold, in this case the word D, amount sold, is always stored in its original form and is identified by the code W E . The data to be stored in a memory 21, Fig. 1, such as a card, a semiconductor memory, or a magnetic drum, disc or tape is supplied from a main memory 11 to a concidence detector 15 and memories 12, 13, 14, such as shift registers, connected in series. Read-out from memory 11 is stopped when the block positioning code BE at the head of the second block is detected by a code detector 22 and shifting of memories 12, 13, 14 is stopped when the block positioning code BE at the head of the first block is detected by a code detector 24. Up to this point AND gate 16 passes the output of memory 12 to memory 21. Thereafter shift pulses are again supplied to memories 11-14, the corresponding words A, B, C read out of memories 11 and 14 being compared one by one by coincidence detector 15, and when coincidence is detected 15 AND gate 16 is disabled and AND gate 19 is enabled to pass the output of a specific code Pc generator 18 to memory 21. The coincidence detector 15 is disabled on detection of the code W E  so that word D is stored in its original form. The restoration of the original data format is similar, Fig. 10 (not shown) except that detection of the code Pc causes the corresponding word from the preceding block to be gated from an auxiliary memory (136) to the output memory (134).

Abstract: 1,219,701. Pulping waste paper. RIVERSIDE PAPER CORP. 10 April, 1969 [26 April, 1968], No. 18340/69. Heading D2W. Natural and synthetic resins and plastics are removed from waste coated or impregnated papers by extracting the paper with a solvent in an extraction zone, forming a miscella of solvent and dissolved plastics, maintaining the extraction zone at a temperature below the softening point of the plastics, at a pressure sufficient to retain the solvent in the liquid phase, separating the paper stock from the miscella; recovering the solvent by distillation wherein, prior to the precipitation of plastics solids, an amount of a hydrocarbon sufficient to form a flowable residue is added, the hydrocarbon being miscible with the solvent, non- volatile at the temperature of distillation and forms a stable suspension with the precipitated solids. The term "plastics" is used to include resins. The hydrocarbon may be a petroleum hydrocarbon. The solvent may be tetrachloroethane, trichloroethylene, ethylene dichloride, pentachloroethylene, perchloroethane, toluene, xylene or decalin. The process may be performed continuously or in batches, when miscella from one batch may be used to contact more fresh batches. In a preferred arrangement, each batch is first contacted with solvent which has contacted two previous batches, then with solvent which has contacted one previous batch, and, finally, with fresh solvent.
