Abstract: 672,662. Optical projection systems. PHILCO PRODUCTS, Inc. June 11, 1946 [June 23,1945], No. 17418/46. Class 97 (i). An image-projection system comprises an image-producing device (e.g. a cathode-ray tube) disposed in the path of projection and masking the system's aperture, means including a cylindrical element for reproducing the image and stop means disposed in the path of projection and comprising opaque elements shaped and dimensioned, in accordance with the aforesaid masking, to effect central masking. of the aperture and thus render the width of the aperture substantially constant in the direction of the axis of the cylindrical element. In the system shown in Fig. 3 light rays from the image formed on the screen t of a cathode-ray tube T are reflected by a spherical mirror M through a Schmidt plate C on to a cylindrical receiving screen S, which may be of the lens mosaic type or of the type disclosed in Specification 6077/48 (as open to inspection under Sect. 91), and which is disposed with its geometrical axis horizontal. It is shown in the Specification that the bright. ness of the image reproduced on screen S is dependent only on the horizontal aperture of the projection system. In order to prevent the variations of brightness of the reproduced image, the horizontal aperture of the system is rendered constant by forming stop elements S<SP>1</SP>, S<SP>2</SP> on the correcting plate C as by painting. As shown in Fig. 2, these opaque elements S<SP>1</SP>, S<SP>2</SP> are bounded by intersecting arcs, which are tangential to the masked area V due to the neck of the tube T and are struck from centres d<SP>1</SP>, d<SP>2</SP> on a horizontal line through the centre of area V with radii r<SP>1</SP> and r<SP>2</SP> substantially equal to the radius R of the aperture a<SP>4</SP>of the system.

IPC: C14C3/18
Filed: 1955-06-17
Abstract: Resins suitable for use as tanning agents are made by reacting an anionic resin and a cationic resin in quantities such that the product is neutral.  The anionic and cationic resins are both made by a process which includes condensing an organic compound containing an amino- or imino-group with an oxo-compound; the anionic resins being defined as resins of anionic character containing in the molecule one or more acid groups capable of forming salts and rendering the resin or salts thereof soluble; the cationic resins being defined as resins of cationic character containing in the molecule one or more basic groups which render the resin or salt thereof soluble.  Specified amino- or imino-group containing compounds are urea, thiourea, cyanamide, guanidine, alkyl guanidines, dicyandiamide, dicyandiamidine and melamine.  Specified oxo-compounds are formaldehyde, acetaldehyde, acrolein, furfural and methyl ethyl ketone. Specified anionic coupling agents are the alkali sulphites and bisulphites, amino-carboxylic acids, aminoalkyl sulphonic acids, aromatic and amino-aryl sulphonic acids, hydroxy carboxylic acids, hydroxy-sulphonic acids and formaldehyde sulphoxylic acids, e.g. taurine, aminoacetic acid, naphthalene sulphonic acid, sulphanilic acid, lactic acid and isethionic acid.  Cationic coupling agents specified are ammonium compounds, polyamino compounds, hydroxy alkyl amines, oxazolidines and polyphenyl biguanidines, e.g. triethylene tetramine, tetraethylene pentamine, dimethylamino-ethanol and diethanolamine.  Known cationic resins, e.g. the condensation products of oxo-compounds with urea, cyanamide, guanidine, biguanidine, dicyandiamide, guanyl urea or melamine may be used per se in the process of the invention.  Part of the starting resins may be replaced by equivalent quantities of anionic and/or cationic surface-active aliphatic compounds, e.g. quaternary ammonium compounds, soaps, alkyl sulphates and sulphonates and alkyl benzene sulphonates.  The neutral products may be formed in situ on the material to be tanned.  In the examples, cationic resins made from formaldehyde and (1) and (2) dicyandiamide and guanidine hydrochloride, (3) dicyandiamide and (4) phenol and dicyandiamide are neutralized with resins prepared from formaldehyde, dicyandiamide and (1) and (2) sodium bisulphite, (3) sulphanilic acid and (4) phenol and sodium bisulphite.  Examples (5), (7), (8) and (9) relate to the deposition of one resin on the material to be tanned with subsequent neutralization thereof; the anionic resins being made from dicyandiamide formaldehyde and sodium bisulphite whilst the cationic resins are made from dicyandiamide and formaldehyde and, in Examples (5), (8) and (9) guanidine hydrochloride.

Abstract: 563,940. Oxides of chlorine and nitrogen. EVANS, C. H. Dec. 11, 1942, Nos. 17647/42 and 15073/43. [Class 1 (ii)] In apparatus of the kind described in Specification 541,754 for the production of chlorine dioxide and nitrogen oxides in which a sodium chlorate-sodium chloride solution and sulphuric acid flow in a spiral course 2 formed in a shallow tray 1 having a slightly coned or concave surface, a flushing tank 115 is provided and adapted to discharge water through a pipe 120 into the generator if the pressure of air in the apparatus fails, so that the reagents are diluted and the production of chlorine dioxide ceases. The waste acidic liquors pass to a generator for nitrogen oxides as in Specification 541,754 and the admission of air to this generator may be restricted so that only nitric oxide is produced within the generator and the formation of nitrogen peroxide proceeds only when air is added to the nitric oxide exterior to the generator. In order that the flow regulators 33, 34 and 38 for each reagent may operate under a constant head of liquid, there are interposed in each case a liquid-head regulator 77, 78 and 79 similar in sonstruction to the flow regulators. The valves used, such as 40 and 43, are cone.shaped and controlled by gravity. Outlets from the generators are sealed by the use of U-tubes. The air used is saturated with water vapour to avoid crystallisation in the apparatus due to evaporation of water. The gases from the chlorine dioxide generator pass up a pipe 106 or a condenser so as to condense water vapour therein and this passes by the stand pipe 7 to the packed tower 8 below the tray 1 to avoid dilution of the reagents. The discharge gases may be dissolved in water by passage through a packed tower containing water. Specification 531,008, [Group XXIX], also is referred to.
