Title: Improvements in photographic films for use in colour photography and in processes for treating the same
IPC: G03C1/95
Filed: 1936-04-25
Abstract: 473,993. Photographic sensitive materials; colour photography. CINE COLOR, Inc. April 25, 1936, No. 11840. Convention date, June 8, 1935. [Class 98 (ii)] Photographic images are prepared from a film having superimposed images therein and one or more relatively reflective strata between the images which strata are either sufficiently translucent to allow the original images to be formed by a single exposure from one side or are originally translucent and are rendered opaque subsequently to the formation of the images, by exposing light-sensitive surfaces to light reflected from the strata. The strata may be insensitive or slightly sensitive. A two-colour film for the process comprises a support 11, Fig. 1, a red-sensitive or panchromatic emulsion layer 12, a separating layer 13, and a blue-green-sensitive layer 14. A red filter dye, e.g. congo red, may be applied to the outer surface of the layer 12 or between the layers 12 and 14. The stratum 13 contains a translucent substance capable of being rendered opaque and reflecting, e.g. zinc hydroxide titanium dioxide, or zinc oxide which are rendered opaque by treatment with a soluble sulphide. Alternatively, it may contain silver chloride or bromide mixed with excess of potassium iodide. The images in the layers may be copied successively onto double-coated film or simultaneously onto separate films, e.g. as shown in Fig. 3 in which the images on the film 10 illuminated by the light source 16 and mirrors 18, 19 are copied by the lenses 20, 21 on films 22, 23. When three sensitive layers are used, the image in the upper layer is copied and this layer then removed together with the underlying stratum.

Title: Process for the manufacture of filament yarn having protruding filament ends
IPC: D02J3/02
Filed: 1974-03-18
Abstract: 1442499 Producing filament yarn with protruding filament ends HOECHST AG 18 March 1974 [17 March 1973] 11889/74 Headings DID and D1F In a process to manufacture a filament yarn with protruding filament ends, the yarn comprising, at least partly, filaments of a polymeric material whose lateral bending resistance can be thermally influenced, the yarn is subjected to a heat treatment along certain sections of its length only to confer differing lateral bending resistance to the filament sections and then the yarn is subjected to a transverse stress which breaks the filament sections having the lower lateral bending resistance. The heat treatment may be carried out by means of a heated roller having a recessed surface which engages the yarn. Alternatively, the heating may be by means of pulsed infra red radiation or an intermittent hot steam jet. The thermally influencable filaments may be blended with non thermally influencable filaments to give a stronger yarn, in this case a small amount of twist is preferably applied. The transverse stress may be applied by drawing the yarn over an edge, by twisting or by false twisting. the latter having the advantage of producing a bulked yarn. The filaments may be mixed by interlacing or by electrostatic means. Prior to making up the yarn may be sized or interlaced to reduce the protrusion of the filament ends. Examples are given which relate to a blended yarn of polyethylene terephthalate and trimethoxysilane-ethanephosphonic acid diethyl ester with manganese acetate, details of the filament tex and heated roller dimensions being given. British Specifications 924086 and 1208801 are referred to and German Auslegeschrift 1720647 and U.S. Patent 2398729 are referred to in connection with the filament production in the examples.

Abstract: 731,269. Automatic feed weighers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 12, 1953 [May 12, 1952], No. 12037/52. Class 143. Apparatus for measuring the mass flow of viscous liquid, e.g. of heavy fuel oil to a burner, comprises a tank 1 mounted on a counterbalanced weighbeam 2, a valve 7 supplying the tank which automatically is closed when the beam 2 is overbalanced by the tank 1 being filled up, a platform 9 which is raised to remove an additional counterweight 8 loading the weighbeam after balance has once more been restored by liquid flowing from the tank through a pipe 4 by siphoning or other action, a time device, e.g. stopwatch, which is started on balance being obtained and is stopped by the beam returning to balanced position after liquid has flowed from the tank of weight equal to that of the removed counterweight 8. The platform 9 is then again lowered to add the counterweight 8 on the beam and the valve 7 re-opened and the cycle of operations repeated, the watch being reset to zero each time balance is achieved with the counterweight 8 on the beam. The sequence of operations is controlled by mercury cup switch contacts 38, 41 co-acting with contact members depending from the weighbeam in series with a mercury coupling switch 40, two pairs of switch contacts 34, 35 alternately closed when the supply valve 7 is raised and lowered to open and close it, two pairs of contacts 37, 36 alternately closed when the platform 9 is raised or lowered, the interconnection of the switches energizing relays 42-48 resetting the watch, starting it and stopping it, and energizing solenoids 27, 28 and 29, 30 which operate the valve 7 and platform 9. The switch 37 stops the watch but is not closed when the platform 9 is raised to remove the counterweight 8 as the weighbeam overbalances first. The valve 7 and platform are operated by cams 13, 15 on camshafts carrying at each end a pair of oppositely extending arms 17, 18 and 23, 24, each pair on a camshaft being at right angles and alternately engaged by driving pegs 22, 26 on driving members 19, 25 which can be axially slid on a constantly rotating drive shaft 20 to engage one or other of the pegs with the corresponding pair of extension arms 17, 18. The camshafts are thus rotated by a quarter turn each time and the cams, being elliptical, raise and lower the valve and platform. The driving members are axially displaced alternately by the solenoids 27, 28 and 29, 30, when energized, through pivoted levers 192, 252. The platform 9 may have a boss 10 locatingly engaging a recess 11 on the underside of the counterweight 8, the latter forming a scale pan to which additional weights may be added. An indicator lamp may be lit during the watch resetting operation.

Title: Improvements in or relating to tertiary-alkyl isocyanates
Filed: 1951-05-23
Abstract: Tertiary alkyl isocyanates of the formula <FORM:0689872/IV (b)/1> wherein C1 is a tertiary carbon atom and R1, R2, R3 are alkyl groups or R1 and R2 together with C1 form a cycloaliphatic radical, the total number of carbon atoms in the three R groups being 3-18, are prepared by heating a mixture of urea and a tertiary alkyl amine <FORM:0689872/IV (b)/2> at 90-150 DEG  C., mono- and di-substituted ureas being formed, and then heating to 180-250 DEG  C. to decompose the ureas into the isocyanate and ammonia or amine.  The products are quenched as by leading into cold aqueous acid when the isocyanate separates as an organic layer which is separated.  An excess of urea is preferable but mixtures containing 25-75 mole per cent of either reactant are suitable.  With low boiling amines pressure is employed. Examples of R groups range from methyl to 2-ethylhexyl, lauryl, and hexadecyl, and R1, R2 may form part of a tetra- or hexa-methylene group.  In examples: (1) 1 mole of urea is heated with 2.5 moles of neopentyldimethylcarbinylamine at 129 rising to 185 DEG  C. to form the di-substituted urea which is vaporized at 205-215 DEG  C. into cold acid, and the organic layer distilled to yield neopentyldimethylcarbinyl isocyanate; (2) equimolar amounts of the same reactants are used; (3) 1-methylcyclohexylamine-1 and urea are converted as in (1); (4) iso-octyldiethylcarbinylamine is similarly converted; (5) tert.-butylamine and urea are autoclaved at 90-130 DEG C. with periodic venting of ammonia, and the product vaporized into acid to recover tert.-butyl isocyanate.

Abstract: 1329228 Electron guns UNION CARBIDE CORP 30 April 1971 [1 May 1970] 12369/71 Heading H1D An electron gun for a welding apparatus comprises a thermionic cathode 15, Fig. 1, disposed opposite an apertured main anode 19 and heated by electrons from a glow discharge between an auxiliary cathode 1 and anode 7. The auxiliary cathode is preferably concave in order to focus the emitted electrons on to the main cathode, and the radius of the concavity is preferably twice the cathode radius. The auxiliary anode 7 surrounds the auxiliary cathode and may be connected to the main cathode by a lead 17. In Fig. 1, the auxiliary discharge is produced by a 10KV potential within an insulated enclosure 5 in a gas pressure of 10- 20 microns, and the main gun operates at 60KV in a gas pressure of 0À1 microns. Back-firing is prevented by (a) feeding the gas through a bubbler unit 25 and/or through an insulated tube connected to a gas bottle which is insulated from earth, (b) providing a flange 9 on the pilot anode 7 outside the insulator 2 to move the field stress outside the chamber C, (c) providing an insulating or conductive baffle (not shown) below the gas exhaust apertures 27, (d) providing a control ring 11 in contact with the Faraday dark space and preferably connected to the anode through a high resistance 12, the gas inlet and exhaust apertures passing through the ring. The power of the main beam may be controlled either by controlling the auxiliary discharge or, if the emitting cathode 15 is insulated from the main cathode electrode 16, by altering the bias between these two members. In a modification, Fig. 4 (not shown), the main cathode structure is secured to the bottom of a cup-shaped conductor which forms the wall of the auxiliary discharge chamber. In a further modification, Fig. 5 (not shown), an inner wire mesh or solid cup is attached to the control ring and spaced by a gap or by insulating material from the cup-shaped conductor. Opposite the main cathode the mesh cup has an opening in which a tube may be inserted. The diameter of the opening is such that the main beam can pass through it but fringing electrons are intercepted, and the effect is to stabilize the focus against the effects of changes in pressure.
