Title: Method and means for improving and varying the control of expression in automatic pianoforte players and such like
Filed: 1921-04-19
Abstract: 183,537. Metzger, S. G. April 19, 1921. Player-pianos; controlling handles, levers, and pushes; blowing and exhausting air.-Relates to expressioncontrol in automatic pianofortes operated pneumatically. Two or more vertical buttons, and two or more horizontal buttons operated by the backs of the fingers used to operate the vertical buttons, are provided preferably between a solo lever and the lo.ud pedal lever. As shown, one pair, c, h, controls the divided high or low tension; another pair i, j operates, through pneumatic or mechanical means, the bass and treble portions of a divided hammer rest-rail. The action of the buttons c, h is reversed from softening to loudening the bass or treble respectively, on advancing the solo lever a from position 1 to position 2, the action of the buttons i, j remaining unaffected. Advancing the solo lever a to position 3 produces the further effect of moving the whole hammer rest-rail towards the strings, through not to so great an extent as by operating the buttons i, j. Horizontally and rearwardly pressed levers may be substituted for any of the buttons. Fig. 5 shows the bass side of a control-box, and Figs. 6 and 7 a slide valve by means of which the buttons c, h and the solo lever a operate. With the solo lever in position 1, the main valve e and the governed passage f<7>, lying between the exhaust at e<3>, f<3> and the action connected at v, are both open, and the slide b<1> connected at a<3> by a link a<2> to the solo lever is in the position shown in Fig. 7. Depression of the button c admits atmospheric air by passages c<2>, c<3>, c<4>, c<5>, c<6> to a diaphragm e<1> which thereupon closes the valve c, thereby softening the bass. In position 2 of the solo lever a, the slide b<1> uncovers the passages c<4>, t<4>, the air there admitted normally depressing the bass and treble diaphragms e<1> to close the valves e. Depression of the button c now admits air by passages c<2>, c<3>, e<6>, e<7> to a diaphragm m<x> which raises a valve d to cut off the atmosphere from the diaphragm e<1>, the valve e thereupon opening to accentuate the bass. Automatic accentuation of the bass or treble may be obtained from additional perforations in the tune sheet, by connecting the ducts e<7>, t<7> to the tracker-bar. In position 3 of the solo lever, the slide b<1> moves further to open a pallet k pneumatically operating the soft-pedal rod to reduce the blow of all the hammers.

Title: Polymerisation process
Inventor: ROEBUCK DAVID SAMUEL PETRIE
IPC: C08F4/06
Filed: 1958-04-10
Abstract: In a process for the production of aqueous polymer dispersions having a substantial degree of particle size uniformity, active centres are induced in a surface active agent and a monomer capable of radical addition polymeriatizon is subsequently introduced and polymerized in an aqueous medium by means of the active centres to give the aqueous polymer dispersion.  The active centres may be induced by ultra violet light in the presence of oxygen, g -rays or chemical initiators such as peroxy compounds e.g. tert. butyl peracetate, potassium persulphate and cumene hydroperoxide, preferably in the presence of oxygen, or redox systems, e.g. ferrous pyrophosphate / hydrogen peroxide / fructose.  The surface active agent may be common soap, alkali metal salts of alkyl sulphates, quaternary ammonium halides, e.g. cetylpyridinum chloride and cetyltrimethyl ammonium bromide, and condensates of ethylene oxide with higher alcohols, alkylphenols and mercaptans.  Specified monomers are styrene, acrylonitrile, methyl methacrylate, ethyl acrylate, vinyl acetate, vinyl chloride, butadiene, isoprene and mixtures, e.g. of butadiene and styrene.  Dispersing agents, e.g. condensates of ethylene oxide with higher alcohols, alkyl phenols, mercaptans or long chain aliphatic amines, may be added with the monomer.  The polymerization may be terminated by the addition of hydroquinone or a salt of dimethyl- or diethyl - dithiocarbamic acid, or the reaction may be allowed to proceed to completion followed by the addition of a second monomer to yield block copolymers.  The products may be used as coating compositions and for treating paper.

Title: Improved process for producing multi-layer photographic color negatives containing masking images for color correction purposes
IPC: G03C7/18
Filed: 1948-04-29
Abstract: 638,406. Colour photography. GENERAL ANILINE & FILM CORPORATION. April 29, 1948, No. 11788. Convention date, Nov. 18, 1947. [Class 98 (ii)] A subtractively coloured negative incorporating colour-correction printing masks is made by exposing a multilayer film having silver halide emulsion layers sensitive to the blue, green and red regions of the spectrum and containing colour formers to a coloured object, colour developing, short stopping in an acid bath, washing, bleaching the developed silver to silver bromide, exposing to a controlled quantity of white light, developing in a black and white developer containing 0.02 to 0.4 gram of potassium iodide per litre, fixing, washing and drying. Silver masks are thereby formed in the magenta and cyan coloured layers (originally green and red sensitive, respectively) but not in the yellow coloured, blue sensitive layer. The function of the potassium iodide is to control the extent below the top surface of the emulsion layer at which development will start, it desensitizes the upper strata of the emulsion layers, but in the deeper sections the developer acts normally since the potassium iodide will not have penetrated to these deeper sections. The reformed silver bromide in situ with the coloured images is much less sensitive than the residual silver halide left after colour development and so the controlled exposure to white light does not form latent images therein. In an example, this controlled exposure is 15 seconds at 5 feet from a 100 watt lamp and the colour developing, the bleaching and the depth-developing solution with the potassium iodide are specified. Specifications 458,400, 465,823, 541,266, 637,876 and 637,879 are referred to.
