Title: Improvements in or relating to fluid pressure brakes, particularly for cycles or thelike
IPC: B62L3/02
Filed: 1953-02-25
Abstract: 745,061. Fluid-pressure brakes. DUBOIS, E. D., and MORELLI, V. Feb. 25, 1953, No. 5244/53. Class 103 (1). [Also in Group XXXI] In a fluid-pressure brake suitable for bicycles, motor-cycles and the like, a pump cylinder or master cylinder a is adapted to compress the operating fluid to operate an actuating cylinder c adapted to actuate the brake shoe carrying levers d. Connecting the two units a and c is a flexible tube 28. In operation, assuming the device to be completely filled with the pressure fluid and all air eliminated from the system, the hand lever 13 of the pump cylinder a is depressed thereby pushing piston 5 downwardly to compress the fluid within the cylinder 2. The pressurized fluid is transmitted through flexible tube 28 to a flexible expansible member 37, within the actuating cylinder c, which when expanded, operates pistons 43 outwardly, within the cylindrical portions 36 of the housing 35, and with them, sliding members 45 which extend through cap members 48. Adjustable screws 46 screwed into the sliding members 45 operate the brake shoe-carrying levers d to effect a braking action of the shoes 49 on the rim of the wheel. When the hand lever 13 is released, the combined action of springs 50 and 17 will return all parts to their inoperative positions. The flexible cover 9 surrounding the piston 5 provides a fluid-tight seal for the cylinder 2 when the piston is in its uppermost position. The pump cylinder a may be adapted to be releasably secured to the steering handle b of the bicycle or like vehicle and the actuating cylinder c may be releasably secured to a suitable part of the vehicle frame.

Title: Improvements in or relating to the production of effects on materials made of or containing organic derivatives of cellulose
IPC: D06P5/15
Filed: 1931-02-19
Abstract: Cellulose esters or ethers, dyeing; printing.--White or coloured discharge effects are produced on materials made of or containing organic esters or ethers of cellulose by effecting the discharge in the presence of steam and of an ester of an organic or inorganic acid.  Specified esters are the acetins, glycolchlorohydrin, glycerolmono- or di-chlorohydrins, diethyl tartrate, and potassium methyl (or ethyl) sulphate.  The discharge may be effected by oxidizing agents, e.g. chlorates, or by reducing agents, e.g. the formaldehyde sulphoxylates of sodium or zinc, and the discharge preparations may contain catalysts such as anthraquinone.  In an example a mixed fabric containing cellulose acetate and cotton is dyed with p-aminobenzeneazodimethylaniline and Chlorazol black LF, subjected to diazotization and development with b -oxynaphthoic acid, printed with an aqueous paste containing zinc formaldehyde sulphoxylate, gum arabic, methylated spirit, and triacetin, aged for 7 mins. in a Mather-Platt ager, washed, soaped, again washed, and dried to obtain a white discharge on a black ground.

Abstract: 1467571 Polyesteramides; elastomeric amide linked polyurethanes UPJOHN CO 11 Feb 1975 [11 March 1974] 5778/75 Heading C3R Polyesteramides are produced by reacting in the presence of a basic catalyst (a) a polymalonate where n corresponds to an average molecular weight of 800 to 5000, R is the residue of a diol HO-R-OH which is an alkane or cycloalkane diol, poly(alkylene glycol), di(hydroxyalkyl)ether of a dihydric phenol or bis-(hydroxyphenyl)alkane, and R<SP>1</SP> and R<SP>11</SP> are independently, H, hydrocarbylcarbamoyl or acyl from a hydrocarbon monocarboxylic acid, with (b) an organic polyisocyanate in excess of the amount required to react with any OH group in (a). When R<SP>1</SP> and R<SP>11</SP> are not H the mixture of (a) and (b), with or without the basic catalyst is storage-stable and such mixtures are claimed. The polyisocyanate may be an isocyanate terminated prepolymer of a polyol of M.W. 250 to 4500. Specified basic catalysts are t-amines and especially aminimides of the formula where R 1  to R 5  are hydrocarbon radicals, two of which may be joined to complete a ring; these decompose to form t-amine plus isocyanate at the reaction temperature of 50‹ to 200‹ C. The product may be modified by incorporating other reactive compounds as commonly used in the polyurethane art, e.g. polyester or polyester polyols, polyamines or alkanolamines, and also pigment, fire retardants or inert fillers. Numerous reactions are specified and the probable reaction mechanism is discussed; it is postulated that the amide links are formed by reaction of a diisocyanate OCN-R 1 -NCO with the CH 2  groups between the CO groups of the malonic radicals to form cross links while some isocyanate also reacts with OH groups to form urethane links and possibly itself to form isocyanurate links.

Anthraquinone derivatives.- 1-Amino-2-chlor-, and 2-amino-3-chlor-anthraquinones are obtained by treating the urea of 3<1>-amino-4<1>-chlor-2-benzoyl benzoic acid with sulphuric acid under ring closing conditions, and separating the mixture of products by dilution. According to examples, the urea of 3<1>-amino-4<1>-chlor-2-benzoylbenzoid acid is obtained by the action of phosgene on the acid in caustic soda solution; this urea is treated with concentrated sulphuric acid, cooled and diluted to separate the 2-amino-3-chloranthraquinone, and further diluted to separate the 1- amino-2-chloranthraquinone. Hydrochloric acid may also be used to separate the products. Specifications 8917/14 and 264,916 are referred to.

IPC: F02D9/00
Filed: 1918-04-09
Abstract: 131,062. Fraschini, O. April 3, 1917, [Convention date]. Spray carburettors.-Engines for aircraft are charged by a compressor which delivers air to carburettors located in a pump delivery pipe containing valve-controlled ports Q for the escape of excess air discharged by the compressor. The ports Q are controlled by a ring valve O carried by a flexible member N. Behind the valve is an airtight chamber M, the pressure in which ensures that the valve will occupy the position shown in Fig. 1, when the aircraft is at ground level. At higher altitudes, the pressure in the discharge pipe falls and the valve advances to close more or less the ports Q. In the event of the compressor being out of action, or, if the ports Q are entirely closed, air may be drawn through the valves T into the carburettors.
