Title: New or improved apparatus for coating paper with wax and the like
Filed: 1929-07-02
Abstract: 335,968. Green, A. July 2, 1929. Coating materials in long lengths.-Apparatus for coating paper with wax comprises a drum heated by steam or other means, to which a regulated supply of wax or other material is applied by a roller dipping into heated wax. The paper is passed over or around the drum and pressed against it by adjustable pressure rollers, and is then passed to cooling drums. The apparatus is constructed in two parts, shown in Figs. 1 and 2 respectively, with a motor or lay shaft a, Fig. 1, between them. Journaled in the frame b is a steam-heated drum c located above a steamjacketted pan d which contains the molten wax. The pan is supported by blocks d<1> which can be raised or lowered through gearing by means of a hand wheel. Dipping into the wax is a clothcovered roller e extending the full length of the drum c and mounted in a frame e<1> which is pivotally mounted on slippers e<2>. The latter may be moved horizontally by means of a rack and pinion actuated by a hand wheel. On the remote end of the pivoted frame e<1> are hung weights e<7> which press the roller e against the drum c. A roller f, normally pressed against the drum by means of springs f<2>, is mounted in bearings in sliding members f<1>. Above this roller is a tensioning roller g mounted in sliding members g<1> adjustable by means of a hand wheel in order to take up slack in the paper web. Above the roller c are mounted two pressure rollers k, l journaled in members i sliding in guides b<4>, b<5>. These rollers are pressed against the roller c by means of springs i<1>, the tension of each of which may be adjusted by means of hand wheels i<7>. The rollers are positively adjusted relatively to the drum c by means of cams or eccentrics mounted on cross shafts m<1> journaled in the side frames b and passing through clearance slots in the members i. The eccentrics bear against lugs on the members i, and are locked in position by means of notched wheels m<3> which are engaged by dogs m<4>. At the top of the frame is a cooling drum n, driven from the drum c by means of a crossed belt n<3>. A scraper n' bears against this drum. The second set of frames o, Fig. 2, carries two cooling drums p, q, around which the paper passes. The paper then passes around guide rollers q<2>, q<3>, q<4>, and between two shafts r<1>, r<2>, geared together and provided with slitting knives to trim the edges and to slit the paper down the middle. The two lengths of paper are wound up on separate rolls s, t, driven by friction rollers s<1>, t<1>. The paper to be coated is taken from a reel h, Fig. 1, mounted on brackets b<6> and provided with a brake b<7>. The amount of wax applied is regulated by varying the pressure of the roller e against the drum c. Both sides of the paper may be waxed by leading it first around the feed roller e so that it passes through the wax before passing around the drum c.

IPC: B01F5/04
Filed: 1926-08-18
Abstract: 257,274. Geigy Akt.-Ges., J. R. Aug. 22, 1925, [Convention date]. Emulsions, making.-In a process and device for mixing liquids or fused materials for the purpose of carrying out reactions or producing dispersion systems, the material or materials constituting the disperse phase are atomized in known manner by a vapour or gas under pressure and are then forced through a sheet of a continuously supplied dispersion medium to obtain therewith a very intimate mixture. The material constituting the disperse phase enters a chamber h through an inlet i and is blown by steam from a nozzle g<1> through an aperture, in the wall of the chamber where it encounters a sheet of dispersion medium, the medium having been supplied continuously to a jacket k up which it flows to pass down a conical tube n within the jacket. The jacket serves to cool the mixture as it is discharged and the degree of mixture is increased by the friction between the mixture and the wall of the conical tube n. A small quantity of the dispersion medium may be initially mixed with or atomized with the disperse phase; in the latter case, two appliances such as that shown are used in series. The process is stated to be applicable to the preparation of emulsions of bitumens and pitches, and to the purification or saponification of oils by the intimate mixture therewith of purifying or saponifying agents. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the device shown in Fig. 1 (Cancelled). The dispersion medium is supplied continuously to the chamber d and the disperse phase is blown through it from the nozzle a, the mixture flowing away through a conical mouth f.

Title: Improvements in methods of milling screw threads
IPC: B23G1/32
Filed: 1928-07-18
Abstract: 310,240. McLeod, R. J. July 18, 1928. Milling screws. - In a machine for milling screw-threads by means of hobs having the same pitch as the work, a differential gearing is provided for varying the relative speeds of the hob and work to avoid the formation of facets, means being also provided for giving compensating relative axial traverse to the hob. A gear box 11 which may be coupled to a motor at 12 imparts a four-speed and reverse drive to a shaft 21 which is connected through further reversing gearing 18 to drive a spindle 3 carrying the work 1. The shaft 21 is connected through differential gearing 22, bevel gearing 23 and worm gearing 24 to the hob spindle 6. When cutting a screw to depth the differential gearing runs idle but for multiplying the number of facets formed in this operation the rotation of the hob is modified by imparting to it an additional rotation. For this purpose the spindle 21 is connected through gears 27, reversing bevel gearing 26, bevel gearing 28, change speed gears 29 and worm gearing 31 to the casing of the differential. Corresponding axial movement is imparted to the hob from the gearing 26 through a shaft 32, gears 33, change gears 35, worm gearing 37 and lead screw 38 operating the hob saddle 9. The hob may be fed to depth by means of a screw 39 and a former plate 40 may be used for screwing taper threads. The reverse gear 17 enables the whole machine to be reversed to take a fresh cut while maintaining the exact relative positions of the threads on the hob and work. The change gear 13 - - 16 enables the return movement of the hob and the finishing cuts to be effected at high speed.

Abstract: 525,606. Valve amplifying circuits. PHILIPS LAMPS, Ltd. July 19, 1939, No. 21023. Convention date, July 22, 1938. [Class 40 (v)] The bandwidth of a radio receiver or low frequency amplifier is controlled in accordance with the amplitude of the low and intermediate frequency sound signals. High frequencies in the range of disturbing frequencies may operate a control in the opposite sense and the band-width may be decreased by increase in the amplitude of the high and intermediate sound frequencies originating in a neighbouring transmitting channel or in accordance with the carrier wave amplitude in such a channel. The bandwidth control may be effected in accordance with the ratio of the amplitude of the carrier wave and that of the transmitters on neighbouring channels. The control may be effected by varying damping resistances or controlling the core magnetization of iron-cored coils in high or low frequency circuits or by controlling the amplification of parallel connected amplifiers of differing bandwidths.
