Title: Improvements in cinematographic sound-track printing
IPC: G03C5/14
Filed: 1946-05-22
Abstract: 612,370. Printing kinematograph sound films. TECHNICOLOR MOTION PICTURE CORPORATION. May 22, 1946, No. 15491. Convention date, Sept. 29, 1945. [Class 98 (ii)] In imbibition printing from a dyed matrix carrying picture and sound track images, a method, which comprises feeding the matrix into contact with a blank film sensitised in at least the region on which the sound track will be recorded photographically and subsequently developed, is characterised by mordanting the dye in the matrix throughout the sound track zone so that dye is not transferred to the blank and need not be replenished. The mordant may be applied after the matrix has been dyed. Preferably the film is sensitized in the sound track region only with ferric salts, and either a ferricyanide is used to develop the converted ferrous salts, in which case it may be incorporated in the film and the matrix sound record should be a negative, or a ferrocyanide is used to develop the unexposed ferric salts in which case the developer can only be applied to the film after exposure through a positive matrix sound record. As shown a matrix film M passes from a supply reel 12 through a dye tank 13, past an air jet A which removes superficial dye to a device D<1> which mordants the dye in the region of the sound track, a suction device S for removing excess mordant and into a washing tank 14. Preferably the dye used for the matrix from which the sound track is printed is acid and is mordanted with a basic dye. A blank film F to be printed upon passes from a supply reel 7 to a device D which applies a sensitizing solution to the part of the film which will bear the sound track and through a dryer 8. The matrix M and blank F then both pass into a water tank 9 in which they are seated by rollers 4, 6 upon an endless pin belt 1 supported around sheaves 2, 3. The registered films are then passed through a contact printing box 16 wherein the mordanted dye sound record on the matrix is recorded on the sensitized part of the blank F while simultaneously the picture record is imbibition printed on to the blank. The matrix M is then wound off on to a take-up reel while the film F is passed successively into developing and washing tanks 24, 26. If the developer is incorporated in the film, tank 24 may be dispensed with. The film F bearing a picture and a sound track image may then also be wound up, or if further picture images are to be printed on it by imbibition it may be re-seated on the pin belt beneath a second matrix M<1> as at 29 and the film and this matrix finally wound off on to take-up reels as at 32, 33. In a three-colour process involving yellow magenta and cyan the first colour, from which the sound track is also printed, is preferably yellow. Specification 604,256 is referred to.

Abstract: 1349242 Fluid-pressure servomotor systems FRANCE ARMED FORCES MINISTER OF 12 April 1965 [16 April 1964] 15565/65 Heading G3P  A force amplifier in which the pressure of gas acting on a working piston 11 is varied in dependence upon the magnitude of an electric signal applied to a coil 22, the signal causing a needle valve 21 to advance a corresponding distance to variably close an orifice 19, comprises a body 1 having an inlet chamber 2 connected to a gas source 5 having a constant pressure P 1 . A piston 4 slidable in a bore 3 is connected by a rod 14 to a valve member 13, the piston dividing the bore into two chambers 6, 7. When no signal is applied to coil 22 the orifice 19 is fully open and the gas flowing through passage 17 and a small orifice 18 leaks to atmosphere; also, valve member 13 closes orifice 12a and the pressure in chamber 6, 8 and 20 is atmospheric. As the needle valve 21 moves in response to a signal the orifice 19 closes and pressure P 2  builds up in chamber 7 to move the piston 4 and open valve member 13; also, valve member 15 wholly or partly closes orifice 16 so that a pressure P 3  builds up in chambers 6, 8, 20 and acts on piston 11. When orifice 16 is completely closed the pressure P 3  is a maximum and equals P 1 . In a modification Fig. 2, (not shown) the chamber 7 is connected to the gas source 5 through a conduit (24) and small orifice (25) and the chamber 6 continually leaks to atmosphere through an orifice (26).

Patent GB-849045-A (GB)
Title: Improvements in or relating to the deformation of keratinous fibres
IPC: A61K8/23
Filed: 1958-05-16
Abstract: Keratinous fibres, particularly live human hair, are deformed by applying to them, either before and/or after constraining them into the desired configuration, an aqueous solution adjusted to a pH of 9-10 comprising at least one water soluble alkali metal sulphite or metabisulphite and sodium and/or potassium borohydride in the proportion of one mole of sulphite or metabisulphite to 1-20 moles of borohydride, the total quantity of reducing agents employed being such that the concentration of active hydrogen theoretically available is not more than 2 grams per 100 c.c. of p  the aqueous reducing solution, leaving the solution in contact with the fibres for at least 15 minutes and thereafter rinsing, fixing and drying. Specified alkali metal sulphites and meta bisulphites are sodium, potassium and lithium sulphites and sodium and potassium metabisulphites.  The pH of the solutions may be controlled by the use of reactants, e.g. boric acid alone or mixed with calcium chloride, tartaric acid, citric acid, lactic acid, dihydrogen ortho-sodium phosphate, glycine, sarcosine, and taurine, capable of forming buffered systems under the conditions employed.  These reactants may be added in two fractions, the first being incorporated into the treating solution at the commencement of the fibre treatment and the second being applied to the fibres during the course of treatment, e.g. by spraying. The solution may also contain water miscible penetrating agents, e.g. lower fatty alcohols, such as ethanol and iso propanol, glycols and ethers or ether-esters of glycols, and cyclic ethers, e.g. dioxane and dioxolane.  The pentrating agent may also be a binder or carrier, e.g. a polycondensate of ethylene oxide, having uniformly embedded therein the alkali metal sulphites or metabisulphites, the borohydrides and the acid buffing reactant prepared according to Specification 828,208 which is subsequently dissolved in water to form the fibre treating solution.  The solution may also contain water miscible swelling agents, e.g. urea, thiourea, formamide, acetamide and the amides of other carboxylic acids and hydroxy-carboxylic acids, and organic heterocyclic nitrogenous bases, e.g. N-lactarylpiperidine.  After rinsing the fibres may be fixed with dilute hydrogen peroxide or an aqueous sodium bromate solution and dried or they may be rinsed with a dilute solution of a weak organic acid, e.g. lactic or citric acids, and left for reoxidation to take place under the action of the ambient air.  The process may be used for smoothing kinky hair or permanently waving straight hair.  Specification 835,247 also is referred to.

Title: Improvements in or relating to operating mechanism for windows and like closures
IPC: E05F15/08
Filed: 1946-05-24
Abstract: 612,394. Windows operated by fluid motors. TRICO PRODUCTS CORPORATION. May 24, 1946, No. 15862. Convention date, May 25, 1945. [Class 20(iii)] A window 1 or like closure member is operated by a fluid motor having a piston 22 operatively connected by a flexible connecter 26 to two shafts 9 rotatably mounted in the motor chamber 20 at each end, one end of each shaft projecting through an air-tight seal 47 (Fig. 2) to the exterior where it is operatively connected to a flexible power transmission 6 also operatively connected to the window. In the form shown, each end of the cable 6 is wound in a spiral groove 14 on a drum 8 or 8<1> (Fig. 2) on one shaft 9 and the drum 8<1> also has a pulley groove 15, so that the cable can pass from the groove 14 on drum 8<1> over pulleys 7<1> (Fig. 1), 15, 7<1> again, and 7 in that order and down to the drum 8, thus providing active flights 4, 5 which support a vertically sliding vehicle window by means of brackets 3. The cable 6 may alternatively be joined into an endless loop. The pulley 7 and the two-grooved pulley 7<1> are carried on collapsable arms 16, and the drum 8 may contain a counterbalancing spring 58. The other ends of the shafts 9 are enclosed in housings 41 which form continuations of the chamber 20. Each shaft is supported by a roller bearing 46 and the part 45 of a removable cup plate 42, and has a drum 37 mounted thereon with a spiral groove to receive one end of the piston cable 26, the cable being so wound on each drum 37 that it moves towards final coincidence with the axis of the piston chamber as the piston approaches the drum. The drums 37 are smaller than the drums 8 so as to amplify the movement of the window with respect to that of the piston, but may alternatively be made larger. The piston 22 may be of the self-locking type described in Specification 565,137 which prevents the window being forced open. The invention enables the window supporting means to be displaced laterally from the fluid motor which facilitates installation in a vehicle body.
