Title: Improvements in or relating to the transfer of cinematograph picture-carrying layersfrom one film base to another
IPC: G03C7/22
Filed: 1943-02-26
Abstract: 565,838. Stripping kinematograph films; colour photography. TECHNICOLOR MOTION PICTURE CORPORATION. Feb. 26, 1943, No. 3181. Convention date, April 24, 1942. [Class 98 (ii)] A picture-carrying layer is transferred from one kinematograph film base to another in a single apparatus, wherein the outer face of the layer is joined to the new base, and the adhesion between the layer and its old base is weakened, or a preliminary weakening is completed, while the two bases are travelling in superimposition on a carrier, which may be endless, and has a succession of teeth for engaging the sprocket holes of the films; and the new base, carrying the transferred layer, is peeled apart from the old base either while still on the carrier or after the composite film has been removed from the carrier. More than one layer of a multilayer film may be so stripped to provide colour separation records, either by rethreading the films into the same apparatus, or by making provision in the one apparatus for successive stripping operations at different points. Multilayer materials to be stripped may have the same substratum material between the various layers, the successive substrata being softened by controlled penetration of the same solvent; or they may have successive substrata soluble in different solvents, e.g. water and alcohol. The belt may have markings so that when the layers of a multilayer material are being transferred, corresponding sprocket holes of the different films may be caused to engage the same teeth of the carrier in order that slight irregularities in the pitch of the teeth may not impair subsequent registration of the pictures on the films. Fig. 1 shows apparatus for transferring two layers from a film 6, which is first fed from a reel 16, together with a blank base film 10 from a reel 17, into a water bath 20 which loosens the substratum of the first layer to be transferred or initiates the loosening, and also renders the surface of the layer adhesive. The two films are fed between pairs of rollers 18, 19 into superimposition on to an endless toothed belt 12 passing through the bath 20, and are carried by the belt, on leaving the bath, via rollers 23, 25, and the right-hand transport roller 11 of the belt to a roller 26, whereat they leave the belt and enter a drying chamber 29 in which they are stripped apart at rollers 27, with the first picture layer transferred to the new base 10. This, after pursuing a zigzag drying path, emerges to a reel 30, while the film 6, after being similarly dried, proceeds via rollers 32, 33 to a second stripping station further along the belt and identical with the first except that the liquid in the preliminary bath 35 for loosening the substratum of the second layer is alcohol. Here the second layer is transferred in the same way to a new base 34 as the films pass around the left-hand transport roller 11 to a drying chamber 45, wherefrom they proceed to separate reels 46, 47.

Title: Improvements in or relating to motor fuels
IPC: C10L1/06
Filed: 1944-02-21
Abstract: A motor fuel especially suitable for aviation internal combustion engines comprises (i) a gasoline base stock of balanced distillation characteristics which contains low and high boiling constituents so as to permit successful operation under various temperature conditions from below 0 DEG F. up to 130 DEG F. and (ii) a mixture of polyalkyl benzenes boiling in the gasoline boiling range but containing less than 6 per cent. by weight of ortho-substituted polyalkyl benzenes.  The gasoline base stock may be a naphtha whether (a) virgin, produced by hydroforming or produced by catalytic or thermal cracking or (b) produced by the alkylation of isoparaffins with olefins, or a hydropolymer or a hydrocopolymer naphtha or (c) a mixture of the two types (a) and (b).  The base stock may be substantially free from olefins and may contain extraneously produced branched chain paraffins and antiknock agents such as lead tetra-ethyl.  Polyalkyl benzenes which may be present in the polyalkyl benzene mixtures include m- or pxylene, mesitylene, 3- or 4- ethyl toluene, 3-n- or 4-npropyl toluene, 3- or 4- isopropyl toluene, 1,3- or 1,4- diethyl benzene and 1,3 dimethyl-5-ethyl benzene.  The polyalkyl benzene mixture may be produced by mixing together the polyalkyl benzenes or by removing ortho-substituted polyalkyl benzenes from a C8 or C9 aromatic cut.  In the latter case other aromatic substances such as ethyl benzene and n- or iso-propyl benzene may be present.  In examples gasoline base stocks are mixed with C8 or C9 aromatic cuts freed from ortho-substituted polyalkyl benzenes and the resulting fuels are compared with similar fuels in which the aromatic cuts are not so freed.

Abstract: 342,891. Transformers. FERRANTI, Ltd. and PORTER, G. L., Hollinwood, Lancashire. Jan. 30, 1930, No. 3235. [Class 38 (ii).] Cores for polyphase transformers are subdivided longitudinally into a three-limbed part and either two or three two-limbed parts shown respectively in Figs. 3 and 4. The subdivision is designed to facilitate interleaving of the laminations at the joints without increasing the maximum flux density in any part of a limb to the extent caused by other methods of subdivision described with reference to Figs. 1 and 2 (not shown). The increase in flux density may be further reduced or entirely avoided by making the three-limbed part of the core of greater cross-section (up to about 5¢ times greater) than the two-limbed parts as indicated in Fig. 4.

A push button control for a steplessly variabla speed gear 2 driving e.g. a constant-tension textile winding machine, has means for reducing the gear ratio from a predetermined ratio to a creeper ratio and subsequently restoring the predetermined ratio, which comprise an arm 15 rotatable about a spindle 107 and geared to a selector shaft 111 so that when the creeper speed button is depressed a servomotor 27 is started which reduces the gear ratio, through the shaft 111, and drives the arm 15 in a clockwise direction until a spring 15a thereon trips a switch 110a to stop the servo 27 at the creeper speed; subsequent depression of the normal gear button restarts the servo 27 in the opposite direction to raise the gear ratio until the arm 15 trips a switch 109a to stop the servo at the previous gear ratio. The switch 109a is carried by an arm 109 rotatable about the spindle 107 to change the gear ratio. The arm 109 is biased in a clockwise direction by a torsion spring 108 and retained in position by a spring pressed pawl 21 and ratchet 17. For upshift, depression of a " faster " push button starts the servo 27 and rotates the arm 15, whilst the button is held depressed, in an anticlockwise direction a stop 15b of which arm 15 abuts the arm 109 and rotates the latter, the push-button bridging the switch 109a. For downshift, depression of a " slower " push-button rotates the arm 15 in a clockwise direction and energizes an electromagnet 20 which raises the pawl 21 to permit the spring 108 to rotate the arm 109 clockwise. The switch 110a, as shown, is carried by a fixed member 110, but may be mounted on a rotatable arm similar to 109, whereby the creeper speed ratio may be changed.
