[Class 95] [Also in Group IV] A process for spray-coating a surface with a cellulose derivative lacquer containing a concentration of solids producing an undesirably high viscosity for spraying at room temperature, is characterized by providing in the solvent component of the lacquer one or more slowly evaporating constituents of such a character and in such a proportion as to prevent substantial ebullition at the spraying temperature, and to secure the desired flow characteristics in the applied film, heating the lacquer, without decomposition, to reduce its viscosity to that desired at the spraying temperature, and spraying the hot lacquer on to the surface. Spraying temperatures up to 120‹C. or over may be used, but temperatures not exceeding 90‹C. are preferable. The solvent component of the lacquers should have a higher solvent-diluent ratio than that used in lacquers for roomtemperature spraying. Specified ingredients of various solvent-components are ethyl alcohol, ethyl acetate, butyl alcohol, butyl acetate, butyl propionate, methyl lactate, acetone, 1-nitro-butane, diacetone alcohol, toluol, xylol and solvent naphtha. Examples are given of nitro-cellulose-alkyd resin lacquers for application at 25‹C., 90‹C. and 110‹C., of cellulose acetate lacquers for application at 25‹C., 50‹C., 90‹C. and 120‹C., and of ethyl cellulose-ester gum lacquers for application at 25‹C., 50‹C., 90‹C. and 110‹C.

Title: Improvements relating to plant or machinery for effecting cooling and/or drying and desilting operations on granular materials
IPC: F28C3/14
Filed: 1942-09-18
Abstract: 558,808. Separating. COLLINS, J. N., and ASHTON, C. Sept. 18, 1942, No. 11553. [Class 117] [Also in Group XIII] In an apparatus for the cooling and/or.drying of granular materials such as sand and for the desilting or removal of the finer particles therefrom, the material is caused to descend by gravity from shelf to shelf 10 in a tower 8 so as to form a series of cascades through which is drawn air admitted into the tower through a number of openings 13 in one side thereof, the material descending g to a lower portion of the tower in which are disposed suction nozzles 23 adapted to extract the finer particles. The necessary air suction is created by a fan 14 which forces a stream of air upwardly through a column 33 and by an injector action induces through a pipe 33a the drying or cooling air at the upper part of the tower. At the same time the fan 14 directly draws air through a series of nozzles 23 and conduit 22 into a centrifugal separator 21 where the fine particles are separated and descend to a collecting bin 31. The nozzles 23 preferably taper towards their openings in vertical section and are splayed outwardly in horizontal section, and may be adjustable toward's or away from the cascades of material. A valve may be fitted in each nozzle to control the volume of induced air and simultaneously to open an auxiliary air port so that the volume of air entering the separator 21 is undiminished.

Title: Apparatus for feeding material in strips adjustable to any desired length of feed

Filed: 1928-04-20
Abstract: 289,434. Deutsche Post-und Eisenbahn - Verkehrswesen Akt. - Ges. Dapag-Efubag. April 27, 1927, [Convention date]. Feeding and registering webs. -- In apparatus for feeding strips of material intermittently in printing, stamping, vending, stampaffixing, and other machines, the strip is fed by two cooperating rollers, the time during which they cooperate being varied so as to alter the length of strip fed at each operation of the machine, by rotatably adjusting the whole of one of the rollers or of a cam controlling it, relatively to the shaft on which the roller or cam is mounted. In one form, Fig. 3, the strip is fed by two rollers 1, 2 having segmental feeding portions 3, 4, the upper roller being angularly adjustable so that a part only or the whole of the portions 3, 4 co-operate to feed the strip. This adjustment is effected by the rotation of a graduated disc 7 fixed to the disc 1 by a sleeve 6 and adapted to be clamped in adjusted position to a crank handle 9 on the shaft 8 of the roller 1. Accurate positioning of the strip between each feed movement may be effected by pawls 16 operated by an eccentric 18 on the shaft 8 and engaging perforations, notches, or ridges in the strip. In another form, Fig. 4, the strip is fed by a pair of feed rollers 22, 23, carried by pivoted arms actuated by cams 25, 26 which are relatively adjustable to vary the period during which the rollers 22, 23 are simultaneously in contact with the web.

Title: Improvements in or relating to muting devices for radio receiving sets
IPC: H03G1/04
Filed: 1933-04-21
Abstract: 414,474. Valve circuits for wireless reception. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and SMYTH, C. N., c/o General Electric Co., Wembley, Middlesex. April 21, 1933, No. 11723. [Class 40 (v).] The delay voltage of a muting device is increased automatically with increases in signal strength, to render the sharpness of muting more nearly independent of signal strength. As shown, the intermediate frequency of a superheterodyne receiver is applied to the pentode part 1 of a multiple valve V1 the output from which is coupled by a relatively broadly tuned circuit 3, 4 to the diode part 5 of the valve VI whose load circuit comprises a resistance 7 shunted by a condenser 6. The low frequency potentials developed across resistance 7 are fed through a condenser 8 and choke 9 to the triode portion 10 of a multiple valve V2 and thence to an output coupling 12, 13. For automatic volume control, a portion of the output from pentode 1 is fed through condenser 14 to one of the diodes 15 of valve V2 having a load resistance 16. The D.C. potential across this resistance is applied through filter 17, 18 and resistance 19 to the grid of the triode 10 which acts also as a D.C. amplifier, the amplified D.C. flowing in resistance 21. The potential across resistance 21 is used for controlling the gain of the pentode 1 and earlier amplifiers, the control being delayed by the diode 20 of valve V2 which receives a delay voltage and is arranged in series with filter resistances and condensers 29-33 which feed the earlier stages. For muting, a further portion of the output from pentode 1 is fed through a sharply tuned circuit 22 to the paralleled diodes 23, 24 of a multiple valve V3 having a load resistance 25. The triode portion 27 of this valve acts as a D.C. amplifier, the potential across the resistance 25 being applied to its grid and the amplified D.C. flowing in resistance 7. In the absence of signals, this current is arranged to paralyse the detector diode 5, but is reduced to render the detector operative when sufficient current flows in resistance 25. The automatic control of muting is effected by variation in the anode potential of triode 27 due to the inclusion of the resistance 21 in its anode circuit. A visual tuning indicator may be provided actuated by the release of the muting potential.

Abstract: 700,120. Warping and leasing yarns. COURTAULDS. Ltd. May 20. 1952 [May 21, 1951], No. 11786/51. Class 142(4) In a section warping machine a leaded reed is positioned between a split rod frame and the rest of the machine so that the rods need not be removed from the frame to strike a lease. Threads are drawn from a creel and divided into six layers by split rods 3 in a frame 4. The threads pass through the dents of a leaded reed 5 one thread to a dent, and thence to a spacing reed 6 in which one thread from each layer passes through each dent. From, the spacing reed the threads pass under a roller 8 on to a swift 9 to form a section of a warp. To strike a lease a bar 16 is swung into contact with the threads which then ride against stops in the leaded reed 5. A division is thus made between alternate threads and a lease band is inserted between reed 6 and the roller 8. Bar 16 is then removed and a bar 17 swung into contact with the lower surface of the warp sheet to reverse the shed. The leaded 'reed and the split rod frame are mounted on a platform 12 pivotally mounted on a carriage 10 of the warping machine so that the reed 5 and frame 4 can be lined up with a fixed creel whatever the location of. the carriage.
