IPC: C09B1/48
Filed: 1930-04-08
Abstract: Anthrimidocarbazole derivatives.-An a  - amino-anthrimidocarbazole is condensed with an anthraquinone-o-halogen-carboxylic acid or an ester thereof and the product converted to the corresponding acridone in the customary manner.  The anthrimide condensation is advantageously carried out in a high boiling organic solvent, in the presence of an acid-fixing agent and with the addition of a copper salt.  The imides, after isolation by direct filtration, may be converted to the corresponding acridones by heating in concentrated sulphuric acid to about 100 DEG  C.  In examples, (1) 4-amino-1.11-anthrimidocarbazole (obtained by saponification of the 4-benzoylamino derivative) is condensed with anthraquinone-2-bromo-1-carboxylic acid methyl ester, the product isolated, saponified and ring-closed by means of 96 per cent sulphuric acid; it dyes olive green shades from the vat: (2) 4.41-diamino-1.11-anthrimidocarbazole (obtained by saponification of the 4.41-dibenzoylamino-derivative) is condensed with anthraquinone-2-bromo-1-carboxylic acid methyl ester, the product isolated and ring-closed as in (1); it dyes cotton olive-green; (3) 5.5-diamino-1.11-anthrimidocarbazole (obtainable by saponification of the dibenzoylamino derivative) is condensed with anthraquinone-1-chloro-2-carboxylic acid methyl ester and anthraquinone-2-chloro-3-carboxylic acid methyl ester respectively and the products ring-closed by means of sulphuric acid; the products dye cotton brown shades; (4) 5.51-diamino-1.21-anthrimidocarbazole (prepared by condensing 1-benzoylamino-6-chloroanthraquinone with 1-benzoylamino-5-aminoanthraquinone, causing carbazole ring closure in the customary manner, and saponifying the dibenzoylamino derivative with 96 per cent sulphuric acid at about 100 DEG  C.) is condensed with anthraquinone-1-chloro-2-carboxylic acid methyl ester and the product ring-closed by means of sulphuric acid; it dyes brown shades.  The Specification as open to inspection under Sect. 91 (3) (a) refers generally to the use in the above condensation of substitution products of a -aminoanthrimidocarbazoles and of derivatives or substitution products of anthraquinone-o-halogen-carboxylic acids; this subject-matter does not appear in the Specification as accepted.

Abstract: 888,220. Dispensing liquids or semi-liquids under gaseous pressure. HUNT, H. L. Feb. 12, 1960. [April 2, 1959], No. 11232/59. Class 102(2). Apparatus for dispensing liquids or semiliquids under gaseous pressure, comprises an outer casing 1, Fig. 1, closed by a lid 5 fitted with an outlet nozzle 16 and formed with screwthreads for attachment to an adapter member 4 to secure a container 8 open at both ends; within the casing. The container 8 which sealingly abuts the lid 5 houses a follow-up piston 11 subjected on its face remote from the lid by air pressure derived from a pump 13 to eject liquid or semi-liquid from the nozzle. In another embodiment, the container 8 is replaced by a can 28 closed at its bottom end and the follow-up piston 11 by a tube 30 secured to the nozzle and dipping into the can. Air under pressure supplied to the outer casing passes through a hole or holes 31 in the can to act on the surface of the liquid or semi-liquid in the can and so eject it through the nozzle

Title: Improvements in or relating to compressed air brakes for automobile trains
IPC: B60T17/02
Filed: 1937-04-20
Abstract: 479,718. Fluid pressure brakes. KNORR-BREMSE AKT.-GES. April 20, 1937, No. 11269. Convention date, April 21, 1936. [Class 103 (i)] [Also in Group XXVIII] In tractors and trailers the brakes on the tractor are operated by air pressure many times greater than that operating the trailer brakes so that this air pressure can be used directly in the cylinders between the brake shoes and hydraulic transmission can be eliminated, the lower air pressure normally employed for compressed air brakes being used on the trailer. The tractor carries the reservoir and central valve for the trailer brakes, the former being charged from the high pressure reservoir for the tractor brakes, through a reducing valve. The compressor comprises a stepped piston 9 containing a check valve 10 connecting the upper face of the piston to the annular space formed by the step. The crank-case 11 of the vehicle engine is connected by a pipe 12 to the suction space above the piston 9 and is also connected to the crankcase of the compressor to lubricate the compressor. A combined oil separator and pressure regulator 2 arranged on the pump outlet pipe 13 comprises a valve 17 raised when the pressure attains a certain value to admit pressure to a pipe 18 to operate a piston 19 and open a valve 20 so that air from the compressor is byepassed back to the crank-case and oil in the separator is also released to the crank-case, through a pipe 21. The pipe 15 leads to the high pressure reservoir.

A slide projector has a magazine 3 movable in one direction by an electric motor 2 when a rotary transmission member 14 mounted on carrier 15 is moved into direct frictional contact with driving wheel 16 or in the opposite direction when the driving contact is made through an intermediate roller 28. Solenoid 18 is energises momentarily so that armature 19 operates through rod 20 and lever 21 to rotate carrier 15 about pivot 17 against the tension of spring 37 to allow sheel 14 to contact driving wheel 16. Alternatively, for reverse drive, solenoid 35 is used with armature 34, rod 33 and lever 32 pivoted at 22 to rotate carrier arm 29 anti-clockwise through spring 31 and move intermediate roller 28 pivotally mounted at 39 into contact with wheels 14 and 16. Levers 21, 32 engage in turn, and are retained by, catch 25 so that driving contact for reverse or forward motions is maintained. Wheel 14 then drives, through gear train 10, 11, 12, 13, the gear wheel 9 on which as eccentrically mounted push rod 7 pivoted at 8 and driving plunger 6 which in turn drives the slide plunger, not shown. Cam 38 on wheel 9 engages a toothed rack to advance or reverse magazine 3 according to the direction of rotation.

The double bond rearranges during the elimination and provides the required 4,5 bond in the final product. The prepared compounds are particularly valuable for the treatment of androgen-dependent skin disorders such as acne and seborrhoea and of other androgen-dependent disorders associated with skin and hair glands.

Abstract: 507,964. Endless-track vehicles. VICKERS-ARMSTRONGS, Ltd., and LITTLE, L. F. April 20, 1938, No. 11874. [Classes 79 (i) and 79 (v)] An endless-track vehicle is steered by causing the tracks to be laid by the track-engaging wheels or rollers 11 in curved paths, the wheels being so mounted that each one is simultaneously deflected about both a horizontal and a vertical axis to curve the tracks as required. In the construction shown, the wheels 11 are swivelled for steering about inclined axes 26 to produce the desired effect. Each wheel is mounted on a member 19 connected to the chassis frame 10 by upper and lower links 20, 21 and by suspension springs 24. The connections between the links and the members 19 allow of universal movement and are so situated, as shown in Fig. 1, that the axes 26 about which the members swivel for steering are displaced with respect to the wheel centres and are inclined to the vertical, the inclination for the outer wheels being different to that for the inner wheels. The members 19 are swivelled for steering by means of transverse sliding rods 31 controlled by the steering hand wheel 27 through longitudinal sliding rods 29 and gear-boxes 30. Each gearbox 30, Fig. 3, contains pinions 34, 35 engaging a rack 38 on the rod 29, these pinions being integral with pinions 39, 40 engaging a rack 41 on the corresponding rod 31. Thus, when the rods 29 are moved longitudinally, the rods 31 are also moved to an extent depending on the ratio of the two sets of rack-and-pinion gears so as to swivel the wheels 11 to the desired extent. Balancing guide rollers 44, 47 are provided in the gear-boxes 30.
