Abstract: 1,026,656. Endless conveyers. EMHART CORPORATION. Aug. 14, 1964 [Sept. 17, 1963], No. 33190/64. Heading B8A. A machine for depositing containers 12, Fig. 1, on an endless conveyer belt 22 comprises a vibrating transfer plate 10 across which the containers are transferred, e.g. from a lehr 16, to an endless transfer conveyer belt 24, a transfer disc 26, guides 28, 30 disposed above the conveyers and the disc for urging the containers off the belt 24 on to the disc 26 and off the latter on to the belt 22, and a pair of driven rollers 32, 32a for aligning the containers. A return endless conveyer belt 34 is provided for recirculating containers which are not properly routed. The containers fed to the belt 24 are formed in two lines A and B by dividing means 52; a pivotal vane 53 permits accurate lateral spacing of the lines A and B. Unaligned containers 12b are circulated on the disc 26 and are urged outwardly thereof by a stationary tearshaped centre post 27. A fence 52 extends round the disc 26. In a second embodiment, Fig. 2 (not shown), the containers are deposited on the belt 22 in a double line, the guides 28, 30 being replaced by three such guides and the post 27 being dispensed with. The rollers 32, 32a are rotatably supported on members 92, Fig. 3, which are slidably mounted on a beam 76 for lateral adjustment therealong. Such adjustment may permit omission of the dividing means 52. The rollers are driven by an endless chain 98 which is tensioned by a spring 90, the latter also urging a drive pulley 70 into frictional engagement with the belt 34. The direction of rotation of the rollers 32, 32a may be reversed by connecting the spring 90 between anchorages 89 and 91b instead of between anchorages 89 and 91a, Fig. 4 (not shown); the spring 90 when thus connected urges the pulley 70 into frictional engagement with a pulley 104 mounted on the pulley shaft 102 associated with the belt 34. By alteration of the run of the chain 98 the rollers 32, 32a may be rotated in the same direction, either clockwise or anticlockwise, Figs. 5 and 6 (not shown).

Title: Production of black-and-white photographic pictures
IPC: G03C7/30
Filed: 1936-12-11
Abstract: 490,517. Photographic processes. GROVES, W. W. (I. G. Farbenindustrie Akt.- Ges.) Dec. 11, 1936, No. 34052. [Class 98 (ii)] Photographic silver-free black-and-white pictures are obtained by the use of a silver halide emulsion layer containing a dyestuff component which is converted into a black dyestuff and which is fast to diffusion in the binding medium of the emulsion, for example, N-dodecyl-1- : 2-hydroxynaphthoyl-2<1>-aminocarbazole, mdodecoylaminophenylhydroxynaphthothiazolesulphonic acid and 4 - (alphahydroxynaphthoyl) - 4<1> - (p - nitrobenzoylacetyl )- di-chlorobenzidide. The silver is removed after the production of the dyestuff picture by a suitable solvent, such as Farmer's reducer. The dyestuff picture may be produced by simple or reversal colour development using a developer such as p-diethylaminoaniline, by azo-coupling as described in Specification 436,587, or by destroying the dyestuff component or the dyestuff produced therefrom directly or indirectly by way of the silver image. The dyestuff components may comprise a coupling group linked to a polynuclear group, or may be formed by linking components individually forming different colours, for example, blue, green, and red, or blue and yellow, on colour development. The components may be linked by linking carboxyl, amino, hydroxy, or sulpho groups to yield acid amides or esters. The components may be rendered fast to diffusion, as described in Specifications 436,587, 458,400, 465,823, 479,838, 483,000, 484,698, 489,093, 489,161, and 489,274. Substituents such as nitro-groups or halogens may be introduced into the components to increase the depth of black of the resulting dyestuffs, and in colour development colour developers containing such substituents may be used. The dyestuff produced may be converted into a darker dyestuff by diazotization and coupling with azocoupling components or by the action of diazocomponents on such dyestuffs. The process may be applied to the production of sound films. A mixture of several dyestuff components may be used. The components may be in several layers arranged on one or both sides of the support. Specifications 468,946, 481,501, and 488,853 also are referred to. The Provisional Specification refers also to the addition of the components to the developer.

Title: Improvements in and relating to the production of cellulose ethers
IPC: C08B11/155
Filed: 1945-12-20
Abstract: Acetone-soluble cyanoethyl cellulose ethers are prepared by reacting the water-soluble or water-insoluble cyanoethyl ethers prepared in the parent Specification with acrylonitrile in the presence of an amount of water which does not exceed 16 per cent of the weight of acrylonitrile and 400 per cent of the weight of cyanoethyl ether used, and a strongly basic water-soluble compound as catalyst.  A two-phase reaction mixture is preferred, and this is maintained by restricting the weight of water to not more than 10.5 per cent of the weight of acrylonitrile (this being the solubility of water in acrylonitrile at 75-77 DEG  C.).  The time of the reaction depends on the temperature as well as on the concentration of the catalyst, and it is preferred to use a temperature just below 75-77 DEG  C., the boiling-point of acrylonitrile.  Suitable catalysts are sodium and potassium hydroxides, and quaternary ammonium hydroxides such as tetramethyl ammonium, tetraethyl ammonium, methyl tribenzyl ammonium and dimethyl dibenzyl ammonium hydroxides.  The preferred proportions are 0.1 to 2.0 per cent of sodium and potassium hydroxides and 1.0 to 4.0 per cent of quaternary ammonium hydroxides calculated on the weight of the cyanoethyl ether used. The acrylonitrile should be in excess to the extent of 5-30 parts by weight for each unit part by weight of cyanoethyl ether.  The products of the reaction contain 2.4 to 3.0 cyanoethyl (-O-CH2-CH2CN) groups per anhydroglucose unit, and are soluble in acetone, methyl ethyl ketone, acrylonitrile, pyridine, beta-methoxy-propionitrile, beta-ethoxy-propionitrile and meta-cresol and insoluble in methyl, ethyl and butyl alcohols, ethyl acetate, butyl acetate, methyl isobutyl ketone, beta-isopropoxy-propionitrile, beta-n-butoxypropionitrile, benzene, toluene, cyclohexanol and light petroleum.  Their solutions may be spun into filaments and threads, or cast into films.  In an example, 5 parts of a water-insoluble, alkali-soluble cyanoethyl ether containing 0.24 (-O-CH2-CH2CN) groups per anhydroglucose unit prepared according to example (2) of the parent Specification are soaked for half an hour in a solution of sodium hydroxide containing 10 grams per litre.  After removal from the solution, the ether is centrifuged so that it retains its own weight of solution and refluxed at 75 DEG  C. with 100 parts of acrylonitrile. Complete solution takes about 30 minutes, and after this period the mixture is neutralized with acetic acid, the excess acrylonitrile distilled off, the residue dissolved in acetone and the ether precipitated by the addition of ethyl alcohol, filtered off, washed and air dried.

A " flywheel " synchronizing circuit for television receivers in which the separate phase discriminator normally used for comparing the phases of the synch. pulse with that of the scanning waveform derived from the scanning circuits is eliminated and the synch. separator valve 7 performs this function, an A.C. voltage of basically saw-tooth waveform being fed back from the scanning circuits to the anode of the valve 7, any phase difference between the synch. pulses appearing at said anode and the feed-back voltage varying the anode voltage which voltage is used to control the frequency of the scanning oscillator 1. In the embodiment shown, the video signal is applied to the grid of synch. separator valve 7 so biased by capacitor 8 and resistor 9 that only synchronizing pulses produce current in the anode circuit which is linked to a D.C. supply through a high resistance 18. The oscillator is a multivibrator 1, and the feed-back signal in the form of a series of square pulses, is derived from the anode of the multivibrator and applied to the anode of valve 7 through a capacitance potentiometer 19, 11. The output from the anode of valve 7 is smoothed and applied to the grid 2 of the multivibrator to control the frequency thereof. The frame synchronizing pulse may be derived from the screen grid of 7. If a blocking oscillator replaces the multivibrator having its grid leak returned to the anode of a triode acting as a D.C. amplifier then the anode output of valve 7 is fed to the triode grid and similarly to the reactance valve controlling a sine wave generator if this were used.
