Title: An improved ball cock for use in refilling flushing cisterns
IPC: F16K47/02
Filed: 1934-05-23
Abstract: 416,368. Cistern valves. PHILLIPPS, M. T., Esplanade South, Henley Beach, South Australia. May 23, 1934, No. 15360. [Class 135.] A ball cock valve has a chamber with an internal annular discharge port co-operating with a slotted piston to open or close communication between the port and the interior of the piston, the latter also having perforations in the end, a central closing pad and a perforated disc held in position by a packing gland. The valve chamber a with annular discharge port a<1> connected to an outlet a<3>, has an inlet o<2> closed by the pad e on the end of the hollow piston d. As the level in a cistern or the like drops, the cam p<1>moves the rod h to the right and the inlet is opened, allowing water to flow into the valve chamber. This water passes through the perforations d' in the end of the piston, through a hole in a disc f and thence by axial and cross passages h<2> in the rod h to the other side of the piston, the latter is thus balanced and it is stated that " hissing " is overcome ; further movement of the piston to the right opens communication between the main ports d<2> and a<1>. No packing is used in the gland for the rod h, but any leak past the valve chamber is carried away through the subsidiary outlet m.

Title: Improvements relating to waveguides
Inventor: RIBLET HENRY JAMES
IPC: H01P5/02
Filed: 1971-05-19
Abstract: 1299032 Waveguide twists H J RIBLET 19 May 1971 [17 July 1970] 15704/71 Heading H1W A waveguide twist comprises successive sections of rectangular waveguide arranged at an angle to each other and inclined walls which replace parts of the walls of the sections and eliminate the abrupt steps between sections. The normal rectangular section is modified by replacing the planar narrow walls with circular arcuate walls centred upon the axis of the section. The modified sections have the same area as the waveguides which it is intended to join by the twist. Part of the twist is shown in Fig. 5, where 1A, 2A are half-lengths of adjacent sections. The sections are preferably onequarter wavelength (#g/4) long, so that the axial distance between planes EFGH and ABCD is equal to #g/4. A suitable inclined wall for eliminating the step LMK is shown in chain line at AEM where the points A, E lie at corresponding corners of the successive half-sections 1A, 2A and the point M lies at the intersection of the broad walls of the half-sections. The line AE lies on an imaginary circular cylinder 10 and the portion JE lies on the narrow wall HEKD of half-section 2A. The other steps are eliminated in a similar manner and Fig. 6H shows the result. Each half-section presents an inductive reactance to the propagated wave and this inductance may be tuned out by enlarging the broad dimension of the twist in the vicinity of each transition. The resultant enlargements 6, 7 form portions of an imaginary annulus 8. Alternatively, the tuning may be provided by screws in the broad walls. The inclined walls may have an area more restricted than shown. Thus, the point M may be chosen to lie somewhere between the corner L and the mid-point of the broad side of the section.

When the roll 20 moves to the right (Fig. 1) the lever 36 and rod 87 are raised and the brake frees the anchor 70 allowing the beam 13 to pay off some warp. The lever 36 and rod 87 then fall and brake the anchor 70. The warp tension depends partly on the weights 39 and partly on the adjustment of the nut 91. The wheel 60 can be unclutched and the shaft 53 and the beam 16 then rotated by a handle.

[Class 98 (ii)] A super-sensitizing combination comprises a dye containing a simple 1 : 3-thiazine ring, which may or may not be a sensitizer and which may contain the 1 : 3-dihydrothiazine nucleus, and a sensitizing dye, such as a 2<SP>1</SP>- or 41-cyanine or a carbocyanine such as a #- alkyl carboxy amine. The former dye may be used in colour processes, particularly in silver chloride emulsions, in relatively high concentration so as to absorb the ultra-violet and violet rays. Silver bromide emulsions with or without silver iodide may also be super-sensitized. Numerous examples of both classes of dyes are specified. Dyes of the first class include those with a single methine group or a trimethenyl chain, and those in which the 1 : 3-thiazine ring is linked directly to a reactive methylene group adjacent a carbonyl or thiocarbonyl group. Dyes of the second class may have fused-on benzene rings which may be substituted with groups not affecting the sensitizing ability, such as chlorine or methyl. Specification 498,031 is referred to.

Patent GB-1010973-A (GB)
Title: Improvements in or relating to coloring hair
Filed: 1963-04-24
Abstract: Keratin containing substances especially human hair, and fur are dyed by treating the keratin containing substance with a reagent capable of forming a coloured complex with a metal applied to the substance as a solution.  The reagent applied reacts with the cystine material in the keratin to make available reactive sites on the keratin, with which the metal may form a complex on subsequent application.  After formation of the metal complex a further treatment may be carried out to change the shade obtained. Alternatively compounds which do not react with the keratin but merely coat it may be used thus producing a thin coating on the hair or keratin which is then treated with a metal salt solution, the coloured metal compound being bound to the keratin by said coating.  A preferred pretreatment before treating with the metal is alkaline hydrogen peroxide bleaching, also ammonium thioglycolate, after treatments include the use of an amidoxime of cyanoethye cellulose polymers and thioamide derivatures such as dithooxmide.  Many metals are specified and there are preferably applied to the keratin from aqueous solution especially ammoniacal solutions.

Patent GB-732415-A (GB)
Title: Process for the production of aroylated aminocarboxylic acids
Filed: 1953-06-12
Abstract: Aroylated aminocarboxylic acids are produced by heating an aroylated alpha or omega amino-substituted aliphatic carboxylic acid amide with water or an aqueous ammonia solution at elevated pressure and at a temperature above 100 DEG  C., and preferably in the range 160-180 DEG  C.  By this treatment, hydrolytic cleavage of the aroylated alpha or omega amino-substituted aliphatic carboxylic acid amides of the general formula R.CO.NH.(CH2)nCONH2 occurs, the cleavage being substantially exclusively between the CO and NH2 groups of the acid amide, with the formation of aroylated alpha or omega amino-carboxylic acids.  In the formula, R represents the aryl group and the number n is preferably not more than 11.  The preferred quantities of water or aqueous ammonia are such that the amide is in solution at the reaction temperature.  The acids are obtained from the final solution by acidification with mineral acids.  In examples hippuric acid and delta-benzamido-n-valeric acid are obtained from their corresponding amides.

Abstract: 203,778. Fueeny, F. V., (Banting, F. G., Collip, J. B., and Best, C. H.). June 13, 1922. Hypodermic injections.-A pancreas extract to be injected intravenously or subcutaneously in the treatment of diabetes is obtained from fresh glands by extracting them with a solvent, such as alcohol, which inhibits the action of enzymes on the active substance or hormone and then removing toxic impurities by precipitation. According to an example fresh ox pancreas is minced, mixed with alcohol, and the mixture strained and filtered. The filtrate is treated with more alcohol to precipitate proteins and the solution is distilled under vacuum to remove the alcohol. The concentrated solution so obtained is extracted with ether to remove lipoid substances and, after elimination of the ether, alcohol is again added and the mixture agitated and centrifuged whereby " salted out " saline impurities and more proteins are separated and removed. Additional volumes of 95 per cent alcohol are added to precipitate further impurities and the filtered solution distilled to remove the alcohol. The hormone so obtained is dissolved in distilled water and the solution is standardized by concentration, sterilized by filtration, and a small quantity of a preservative such as tri-cresol is added. Suitable solvents for the initial treatment of the glands are stated to be ethyl and methyl alcohols, methylated spirits, and acetone. Reference is also made to experimental extracts obtained from a pancreas gland which had been caused to degenerate by ligation of the ducts some time previous to its removal from the animal, or from normal foetal or adult pancreas by extraction with alcohol but without purification.
