Title: Improvements in three colour photography
IPC: G03C7/20
Filed: 1920-01-29
Abstract: 148,737. Gleichmar, A. July 25, 1919, [Convention date]. Colour photography.-The component positive prints are printed on a single thin transparent foil of celluloid or other substance unaffected by liquids, which is sensitized with three colour areas. The foil is previously creased and after printing through the back of the foil and finishing the prints the foil is folded so that the prints superpose in register. For paper prints the folded foil is mounted on to paper, card, or the like, the blue film side uppermost. For diapositives the creased foil is mounted between sheets of glass. The Specification as open to inspection under Sect. 91 (3) (a) also comprised a camera for taking the negatives in a form in which they are relatively positioned for direct printing on the foil. The blue and green negatives 5, 4, Fig. 1 (Cancelled) are combined by a folding strip 6 with their film faces in contact and are exposed through a green filter 7 which passes blue and some yellow but absorbs the deleterious red ravs. The red negative 3 is exposed directly through the transparent reflector 2, and is afterwards registered with the green negative and attached by a folding strip such as 6. When opened out the negatives are ready for printing direct on to a single transparent foil as above described. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in and relating to means for making picture or sound records
IPC: G03B31/00
Filed: 1931-01-28
Abstract: 377,944. Associated sound and picture apparatus ; sound records. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. - (Assignees of Taylor, J. B. ; 42, Jackson Avenue, Schenectady, New York, U.S.A.) Jan. 28, 1931, No. 2785. Convention date, Jan. 28, 1930. Void [Published under Sect. 91 of the Acts]. [Class 40 (ii).] Picture and sound films or combinations thereof are provided during production with markings at the ends, and if desired intermediately, to facilitate joining up consecutive films for printing or reproduction in correct relation, and in the case of combined films in correct synchronous relation. Each soundrecording apparatus or camera or combination thereof in a set is provided with marking means which are actuated simultaneously so that a similar mark is made at the end of one film and the commencement of the next. As shown applied to a combination of sound-recording devices 1, Fig. 1, and cameras 2, 3 the marking is effected photographically on the edge of the film outside the perforations by light beams from lamps 15, Fig. 2, arranged in housings 10 and energized from a common circuit 11 with switch 13. Long shot and close-up pictures on different films can thereby be correctly assembled in relation to an associated sound record. The marking devices are positioned along the film in relation to the exposure apertures so that correct spacing between the sound and picture heads in combined sound and picture-reproducing apparatus is provided for. Fig. 5 shows a positive print of associated sound and picture negatives produced separately but simultaneously and provided with markings 24<1>, 30 on the sound record and markings 25<1>, 28<1>, on the picture record to facilitate correct association in assembly end to end.
Patent GB-791320-A (GB)
Title: N-trityl serine and esters thereof
Filed: 1955-08-15
Abstract: The invention comprises N-trityl-serine in its DL-, D- and L-forms and the esters thereof.  The latter are obtained by the action of trityl chloride on a serine ester (or salt thereof) in the presence of a tertiary base and an inert solvent.  The free acid can be made similarly from serine and trityl chloride, but is better prepared by hydrolysis of the esters.  The use of D- or L-serine or an ester thereof gives the corresponding optically active product.  Examples are given of the preparation of the ethyl ester of N-trityl-DL-serine and the hydrolysis to the free acid.  The latter gives a triethylamine salt.

The feed-drum 5, Figs. 1 and 3, is pinned to the shaft 2 and is provided with longitudinal grooves 11 which, when the shaft is rotated, produce the motion of the belt by engaging the links thereof. A sleeve 7 is splined to the shaft and is capable of axial movement thereon. The sleeve has a cam-like surface. 19 which engages with a fixed cam surface 20 formed on a flange 21 of the bush of the bearing 16. A spring 9 arranged between the drum 5 and the sleeve 7 is normally in compression. On rotating the crank 25, the drum 5 revolves and the cartridges in turn are brought opposite the revolving sleeve 7 which, by means of the cam surfaces 19, 20 and the spring 9, is oscillated axially on the shaft 2. Thus each cartridge is pushed an equal distance into the belt which is prevented from lateral movement by the projecting fingers 12, 13, which rotate with the drum 5. The hand-lever 37 is provided to release the sleeve 7 when the motion of the shaft is to be reversed.

Abstract: 505,294. Pressure extraction and hydrogenation of coal. I. G. FARBENINDUSTRIE AKT.-GES. Feb. 7, 1938, No. 3801. Convention date, Feb. 6, 1937. [Classes 32 and 91] In the extraction under pressure or hydrogenation with limited amounts of hydrogen of solid carbonaceous materials made into a paste with liquid or fusible substances, the solid carbonaceous materials are mixed with the liquid or fusible agent by introducing below the surface of the mixture one or more low-boiling liquid substances the boiling point of which is below the temperature of the mixture to be stirred. Low-boiling liquids specified are: fractions of the distillation products or pressure hydrogenation products of petroleums, tars, or fractions of the extraction products of coals &c. ; liquefied propane, butane, alcohols, ethers, esters. The introduction of the low-boiling substances may also be used to cool the reacting materials or control the reaction equilibrium or partial pressure of the reactants, or to heat the reacting materials of the low-boiling substance is highly preheated and under high pressure. The substances may be introduced through pipes protruding through the walls of the reaction chambers and may be recovered from the products. In examples; (1) a mixture of bituminous coal, tetrahydronaphthalene, and cresol is stirred by introducing benzine ; (2) a mixture of bituminous coal and heavy oil from the process under 650 atmos., is stirred, when the pressure difference between entrance and exit exceeds 5 atmos., by introducing pre-heated water.

Abstract: 572,856. Making compound forms. ARNOLD, J. C. (Sobel, M. Merlub-, and Medsker, C. A.). March 24, 1942, No. 3873. [Classes 83 (ii) and 83 (iv)] Uniting by fusion.-In uniting a coating such as of stainless steel or of non-ferrous metals or alloys, such as copper, brass, nickel or bronze, to a backing consisting of a plate, slab or strip of steel, a gas flame having a vaporized flux entrained therein is directed against the backing metal to clean the surface progressively as the flame and backing move relatively to each other, and the coating metal after preheating by an electric current is then melted and flowed on to the backing so as to cause it to cover the surface progressively as soon as it is cleaned. The coating metal in rod form 2 is carried by a traversed head 3 and is heated nearly to melting point by an electric current from a transformer to the terminals of which are respectively connected by wires 5, 4 the rod 2 and the backing 1. The head is connected respectively by pipes 7, 8 to a supply of oxygen and a supply of combustible gas bubbled through a volatile flux such as methyl or ethyl borate or a volatile halide. The flame issues from orifices surrounding the rod 2 which is thus melted. Some of the jets heat the backing at B in advance of the rod 2 and other jets act behind the rod to keep the puddle free from occluded gases &c. The backing may be turned over, if desired, and coated in a similar manner on the other side. If desired, the backing may be traversed relatively to a fixed head 3. The backing may be preheated before application of the coating by a furnace, blow - pipe, electric induction or carbon arc. A backing of substantial width may be coated in a series of traverses or a pair of heads 27, 28 may be used provided with a number of torches and coating metal rods 22, one head being mounted on each side of and inclined towards the rods. One set of jets impinge on the backing in advance of the puddle and the others maintain the puddle molten.
