Title: The manufacture of fast vat dyestuffs
Filed: 1929-10-01
Abstract: Pyrazolanthrone derivatives.-Pyrazolanthrone-2-carboxylic acid halide or an N-alkyl or N-aralkyl derivative thereof (Specification 332,316, [Class 2 (iii), Dyes &c.], is condensed with a cyclic diketone capable of being vatted and containing at least one free amino group. These products when not derived from an N-alkyl or N-aralkylpyrazolanthrone-2-carboxylic acid may be subsequently treated with an alkylating or aralkylating agent.  Or the same products may be obtained by condensing a 1-halogenanthraquinone-2-carboxylic acid halide with a diketone as specified above, and the product reacted with hydrazine. Condensation is effected in a diluent with or without the addition of an acid binding agent.  Suitable vattable amino derivatives of cyclic diketones are a-mono-and di-aminoanthraquinones, aminoanthrimides and their carbazolic derivatives, aminoanthanthrones, aminopyranthrones, aminodibenzanthrones, aminodibenzpyrenequinones and their substitution products and derivatives.  In examples (1) pyrazolanthrone-2-carboxylic acid chloride is condensed with (i), 1-aminoanthraquinone (dyes yellow); the same dyestuff is obtained by treating 1-chloroanthraquinone-2-carboxylic acid-a-anthraquinoneamide in pyridine with hydrazine hydrate, or in aqueous suspension with hydrazine sulphate and alkali; the product may be methylated by treatment with toluene sulphonic acid methyl ester: (ii) 1,4- or 1,5-diaminoanthraquinone ( 1/2 mol.) (dyes yellow) : (iii) 1-amino-4-methoxyanthraquinone (orange) : (iv) 1-amino-4-benzoylaminoanthraquinone (orange-brown); the same dyestuff is obtained by treating 1-chloroanthraquinone-2-carboxylic acid-1\sv-benzoylamino-4\sv-anthraquinoneaamide in pyridine with hydrazine, (2) N-methylpyrazolanthrone-2-carboxylic acid chloride is condensed with 1-aminoanthraquinone; the product dyes yellow; and orange to orange-brown dyestuffs are obtained by replacing the 1-aminoanthraquinone by 1-amino-4-methoxyanthraquinone or 1-amino-4-benzoylaminoanthraquinone, and (3) 4-and 5-chloropyrazolanthrone-2-carboxylic acid chloride is condensed with 1-aminoanthraquinone to yield yellow dyestuffs.

Title: Improvements in or relating to rice products
IPC: A23L1/18
Filed: 1950-12-12
Abstract: A process of treating rice comprises cooking the same in the presence of moisture, drying the cooked rice to a moisture content within the range of about 10-14 per cent, compressing the individual rice kernels and pieces thereof while the temperature of said kernels and pieces is within the range of about 140 DEG -210 DEG F and thereafter subjecting the same to a high temperature whereby they are puffed. In an Example 100 lbs. of rice are mixed with a flavouring syrup made from 2.75 lbs. salt, 13 lbs. sugar and 18 lbs. water and cooked under 15 lbs. steam pressure for 1-2 hours, cooled and dried to about 12-13 per cent moisture in a conventional drum dryer and then tempered for 6-10 hours.  The mixture is then deposited in a thin bed on a vibrating conveyer and heated to a temperature of 160-190 DEG F by means of a series of about 6 infra red radiant heaters above the vibrator and p  electrical strip heaters attached to the bottom of the conveyer. The hot rice falls uniformly from the edge of the pan between flaking rolls set at a pressure to reduce the rice kernels to 0.035 in. thickness.  The compressed grains or pieces are then conveyed to a rotary toasting oven where they are simultaneously toasted and puffed to give a crisp friable toasted and puffed rice product several times the size of the original kernel.  U.S.A. Specifications 1,832,813 and 1,925,267 are referred to.

Abstract: 1,254,539. Photo-electric measurement of recording tape level fluctuations. AGFAGEVAERT A.G. June 16, 1969 [June 26, 1968], No. 30381/69. Heading G1A. Fluctuations in recording level of magnetic recording tape due to variations in structure of the magnetizable layer, are monitored by measuring light scattered from the surface of the layer. The layer comprises a non-metallic binder in which are dispersed magnetic particles oriented in a particular direction. The light is guided on to the surface by a vertical tube to produce a substantially parallel beam incident normal to the surface. Scattered light is measured which energizes in two separate directions, one direction being in a plane parallel to the direction of orientation of the particles and the other in a plane at right angles to this plane. The intensities may be measured separately or combined as to form a ratio. Light pipes can be used to select the two directions and guide light to photo-multipliers. The measuring apparatus is calibrated using tapes of known (including zero) level fluctuations.
