Title: The manufacture of therapeutically valuable sulphone compounds
Filed: 1939-07-26
Abstract: 531,571. Sulphones. WELLCOME FOUNDATION, Ltd., HENRY, T. A., GRAY, W.H., and PLATT, B. C. July 26, 1939, No. 21728. [Class 2 (iii)] 4:4<SP>1</SP>-Diaminodiphenylsulphone is treated with the anhydride, ester-chloride, monochloride, monoester or diester of a dicarboxylic acid to give products which, after splitting off the ester groups, if necessary, contain a substituent- CO.R.COOH, wherein R is described as alkyl or aryl, in each amino group. By hydrolysis, one of the substituents may be removed, leaving a tree amino group. In the case of the use of aryl-o-dicarboxylic acid derivatives, compounds of the type of bis-phthalimido-diphenylsulphones are obtained, which, on hydrolysis, first yield compounds containing two of the above substituents and then compounds containing only one. The latter compounds may alternatively be prepared by treating the sulphone with an aryl o - dicarboxylic acid anhydride or acid ester in equimolecular proportions, followed by hydrolysis. The products, whose salts are water soluble, are useful therapeutically. According to the examples, 4;4<SP>1</SP>-diaminodiphenylsulphone is heated with (1) succinic anhydride to give the bis-succinyl derivative : (2) maleic anhydride to produce the bis-maleyl compound ; (3) ethyl adipate chloriae to form 4:4<SP>1</SP>-bis-adipyl aminodiphenylsulphone diethyl ester, which is hydrolysed to the dicarboxylic acid : (4) methyl azelate chloride, followed by hydrolysis of the diester product, to give the bis-azelayl sulphone; (5) malonyl monochloride to form the bismalonyl compound ; on melting, this decomposes with evolution of carbon dioxide, to 4:4<SP>1</SP>- bis - acetylaminodiphenylsulphone ; (6) oiethyl oxalate to yield 4:4<SP>1</SP>-bis-ethyloxalaminodiphenylsulphone, which is hydrolysed with dilute hydrochloric acid to the bis-oxalamino compound ; hydrolysis with sodium hydroxide solution gives rise to 4-amino-4<SP>1</SP>-oxalaminodiphenylsulphone ; (7) phthalic anhydride to produce 4:4<SP>1</SP>-bis-phthalimido-diphenylsulphone; on hydrolysis, either 4:4'-bis-o-carboxybenzoylamino-diphenylsulphone or 4-amino-4<SP>1</SP>-o-carboxybenzoylamino-diphenylsulphone is obtained, according to the conditions; (8) methyl hydrogen phthalate to form the bis-phthalimido compound, which is then hydrolysed to the dicarboxylic acid ; (9) phthalic anhydride to give 4-amino-4<SP>1</SP>-phthalimido-diphenylsulphone, which on heating with dilute caustic soda solution yields 4-amino-4<SP>1</SP>-o-carboxybenzoylamino-diphenylsulphone ; (10) methyl hydrogen phthalate to produce 4-amino-4<SP>1</SP>-phthalimidodiphenylsulphone.

Title: Improvements in brake mechanisms for tractors and semi-trailers
IPC: B60T11/04
Filed: 1954-07-27
Abstract: 791,951. Tractor-trailer brake mechanism. FARRINGTON, B. C. D., HANDS, H. G., and HANDS (LETCHWORTH), Ltd. July 27, 1955 [July 27, 1954], No. 21967/54. Class 103 (1). In a brake mechanism for a tractor and semitrailer composite vehicle of the kind in which the brakes on the semi-trailer are applied from the tractor through a pair of interchangeable coacting displaceable members mounted the one on the tractor and the other on the trailer, the semi-trailer carries means for automatically deflecting the former member out of the path of the latter member during the coupling operation and for releasing the former member as the semi-trailer reaches its fully coupled position so as to allow the two members to come into operative interengagement. In the embodiment illustrated, a semi-trailer 5 (Fig. 2) is secured to the tractor 2 by means of loadcarrying ramp rollers 4 mounted on the semitrailer 5 which are positively retained in contact with the ramps 1 on the tractor 2 so that the ramp rollers 4 engage within the bights 3a of the stop brackets 3 in the coupled position shown in Figs. 1 and 6. The semi-trailer brakes are operated from the tractor 2 through linkage 14, 15, 7 and actuator spade 6 keyed to cross-shaft 7 which normally underlies a coating vertically displaceable plunger 8 on the semi-trailer 5 thus serving to transmit brake-applying effort to the semi-trailer brakes through brake linkage 17, 16. In order to allow plunger 8 to pass over the rearward free end of the actuator spade 6 when the semi-trailer 5 is being coupled, the spade crossshaft 7 is pivoted with a pair of keyed horizontal arms 9, the upper side of each arm 9 terminating in a rounded boss 10 which rests on the forward end of a cam lever 11. During the semi-trailer coupling operation, the cam levers 11 are engaged by rollers 13 mounted on semi-trailer 5 coaxially with load-carrying rollers 4 (Fig. 2) to engage and depress the cam levers 11 which act on arms 9 to depress the spade 6 in the brake release direction as indicated in Fig. 5, so that its tip is positively held out of the path of the semi-trailer brake plunger 8. When the loadcarrying rollers 4 on the semi-trailer fully enter the stop-brackets 3, the cam lever rollers 13 move clear of the cam levers 11 to free arms 9 and allow space 6 to rise into contact with the semi-trailer brake plunger 8, whereafter it can be operated to the full extent necessary for applying the semi-trailer brakes.
