Title: Method of treating napped or like face finished fabric
IPC: D06B3/16
Filed: 1936-11-09
Abstract: Napped fabrics are dyed and finished in a continuous process by passing them at constant rate relative to, and in brief contact with, a vehicle containing a dyestuff having a low exhaustion rate to impregnate the fabric with the dyestuff containing vehicle, forcing the dyestuff-containing vehicle into the fabric and removing excess thereof by pressure, as by means of press-rolls, and completing the fixation of the dyestuff on the fibres while in transit to finishing devices.  The rate of exhaustion of the dyestuff is related to the initial concentration of colouring matter per unit volume of the vehicle.  The exhaustion rate is maintained substantially constant between 2 per cent and 15 per cent, and the time of contact may vary between ,03 minutes to 2 minutes.  The concentration, temperature, pH value and volume of the bath are maintained constant.  The fabric may have both animal and vegetable fibres or their synthetic equivalents in the backing or in the pile or in both, the dye bath then containing dyestuffs which colour uniformly, or complementary dyestuffs may be used one of which has a greater affinity for vegetable than for animal fibres and the other reverse, in such combinations as will produce the required similar or contrasting effects simultaneously.  The several dyestuffs are so proportioned in the rehabilitating liquor added to the dye bath as to maintain the concentration of each substantially constant, their rates of exhaustion and relative concentrates being independently determined. The dyestuff vehicle may vary and may be made in the form of a paste by thickening with a water soluble or water dispersible thickener. The vehicle may also contain salts capable of dissociation by heat or steam to release acids or acid vapours or gases capable of reacting with dyestuffs to promote exhaustion into and fixation of dyestuff in and on the fibres. Gaseous vapours or gases may be substituted for or combined with the steam employed in the apparatus for fixing the dye. Suitable dyes may include direct dyes or neutral wool dyes or other dyestuffs depending on the character of the fibres.  After fixation or ageing, the exhausted vehicle and any thickener employed is washed from the fabric in a continuous washing operation, the rate of feed of the fabric throughout all the continuous dyeing and finishing operations being from 10 to 30 yards per minute, a certain amount of slack material being provided between certain operations as a reservoir.  After washing, the fabric may be treated with acids, or acid materials, metal salts &c. to improve the fastness of the dye, and, after rinsing, hydro-extraction and raising, napping or opening &c. as by tigering, it may be dried in a continuous type of drier. After drying, the material passes continuously at the same rate through synchronized pile-finishing apparatus comprising raising or opening apparatus, nappers, or tigers, beating, shearing, brushing, humidifying, inspection and packing apparatus.

Title: Improvements relating to the aiming of anti-aircraft guns
IPC: F41G3/14
Filed: 1919-05-13
Abstract: 153,326. State of France. May 18, 1918, [Convention date]. Gunnery calculators.-In anti-aircraft gunnery, the gun corrections to be applied in respect of parallax at the observing station on account of drift and angle of site are ascertained by means of two coaxial and relatively-adjusted graduated sectors 14, 15 pivoted at r and moved automatically by connection with the gun through the cam 12 shaped to give movements proportional to log. tan S where S is the angle of site. The two sectors are relatively set by a pointer 16 positioned on sector 14 according to a scale of log. l (l being the length of the base) and set against a scale on sector 15 representing log. h (h being the altitude of the target). Pointers 18, 20 on sector 15 cooperate with curves drawn on disks 21, 22 which are connected with the gun so as to rotate in proportion to its azimuth. The curves on disk 22 give parallax due to displacement of the target and those on disk 22 give a quantity p's which by a further calculating-appliance (Fig. 2) may be converted into ps, the parallax in respect of the angle of site. In order to minimize the size of the disks 21, 22 auxiliary pointers 17, 19 spaced by a distance equivalent to log. 10 from the pointers 18, 20 may be employed and the necessary corrections made in the readings. The apparatus shown in Fig. 2 comprises a spindle d<1> connected with the gun so as to rotate through angles proportional to the angles of site and provided with a pinion gearing with a rack R terminating in a pointer I adapted to be set on a chart A inscribed with curves of p<1>s. A dial E<1> rotatable with the rack and pointer is graduated to show the resultant correction ps against a stationary index.

Patent GB-793851-A (GB)
Title: Process for preparing a steroid
IPC: C07J71/00
Filed: 1954-10-28
Abstract: A process for the preparation of a highly active corticoid affecting the mineral metabolism, called aldosterone, obtainable from suprarenal glands, comprises first treating disintegrated suprarenal glands with oxygen and then isolating the aldosterone therefrom in free form or as a functional derivative thereof according to a process substantially as described in Specifications 786,562 and 793,850.  The suprarenal gland material may be that from cattle or pigs and is homogenized or cut up.  Homogenization is preferably effected in a buffer solution at a constant pH value and advantageously cortexone is added to the material.  The enzyme systems for the reaction can be made operative by the addition of a suitable substratum, such as those of the cyclophorase system and/or compounds belonging to the citric acid cycle or allied compounds, e.g. citric, aconitic, isocitric, oxal-succinic, a -keto-glutaric, succinic, fumaric, malic, pyroracemic, oxalacetic, malonic, glutaric, adipic, glutaminic, asparaginic, ascorbic, lactic, dioxytartaric acids, aspargin, alanine, glycocol and serine.  There may also be added adenosine-di- or tri-phosphoric acid, di- and tri-phosphopyridinenucleolide, nicotinamide, adenine, adenosine and adenylic acid.  Carbohydrates, and inorganic and organic salts are also preferably added and the pH is advantageously kept at 6.5 to 9.0.  Plasma is a suitable reaction medium, and penicillin may be added as a preservative.  In examples: (1) beef suprarenal glands are homogenized with an ice-cold aqueous solution of sodium and potassium chlorides, secondary sodium phosphate, magnesium sulphate, glucose, sodium fumarate and nicotinamide which has been adjusted to pH 7.5. The pH is prevented from falling below 7.3 by adding sodium hydroxide during the homogenization.  Oxygen is passed through the resulting emulsion at 30 DEG  C. while keeping to pH between 7.3 and 7.5.  The product is then extracted and separated, using the general methods of the Specifications referred to above.  Similar examples are given in which other of the above specified substances are present during the homogenization and oxygen treatment.
