Compounds of the general Formula I and salts thereof wherein R 1  is OH, alkoxy, amino optionally substituted e.g. by alkyl or hydroxy-alkyl groups or by a divalent alkylene chain optionally interrupted by a hetero atom are prepared by hydrolysing a compound of Formula II wherein X represents H, acyl or a group of Formula R 2 -O-C(R 3 )(R 4 )- in which R 2  is alkyl or phenylalkyl and R 3  is H, alkyl or phenylalkyl or R 2  and R 3  together are alkylene, R 4 is H or alkyl and Z is O or S and, if desired, in optional sequence, esterifying or amidating the hydrolysis product, if desired converting the product into a salt, isomerizing a D-isomer if desired and/or if desired resolving a racemate and isolating the L-isomer. Intermediates of Formula II above are prepared for example according to one of the following reaction sequences: 3,5-dihydroxy-4- methoxybenzoic acid is acetylated with acetic anhydride to give the 3,5-diacetoxy compound which after conversion to the acid chloride is reduced to 3,5-diacetoxy-4-methoxybenzaldehyde which on reaction with hydantoin to give 5-(3,5- diacetoxy - 4 - methoxybenzylidene) - hydantoin which may either be reduced to 5-(3,5-diacetoxy - 4 - methoxybenzyl) hydantoin or hydrolyised to the 5-(3,5-dihydroxy-4-methoxybenzylidene) hydantoin and then reduced to 5- (3,5 - dihydroxy - 4 - methoxybenzyl) - hydantoin ; 3,5 - diacetoxy - 4 - methoxybenzaldehyde is treated with sodium in methanol and reacted with chloromethyl methyl ether to give 3,5- bis(methoxymethoxy)- 4 - methoxybenzaldehyde which on reaction with hydantoin forms 5-[3,5- bis(methoxymethoxy) - 4 - methoxybenzylidene] - hydantoin which on reduction yields 5 - [3,5 - bis(methoxy - methoxy) - 4 - methoxybenzyl] -hydantoin.

C. engines of large displacement (e. g. greater than 400 cu, in.) having a relatively low temperature exhaust, comprises a housing having a gas inlet at one end and a gas outlet at the other end, a transverse apertured catalyst support plate intermediate the ends and dividing the housing into inlet and outlet sections, a plurality of ceramic block catalyst section secured to the plate at the apertures therein and kept separate from each other, so that exhaust gases pass from the inlet, through gas flow paths in the catalyst sections to the outlet. The housing comprises an inlet section 8 and an outlet section 9 having flanges 3 and 6 respectively for attachment to the remainder of the exhaust system and flanges 12 and 13 by which they are bolted together and to the catalyst support plate 7. The plate 7 has four apertures, each counter-bored on the side facing the outlet to receive one end of a metal tube which receives a catalyst section 11. The sections are retained by an inwardly projecting flange formed by welding a ring to the free end of the tube. The outer surface of each catalyst section is coated with fibrous aluminium silicate and spaced from the inner surface of the tube by a corrugated, knitted metal mesh, shock-absorbing fabric. The catalyst comprises a skeletal ceramic e. g. alpha-alumina or zircon-mullite, the surfaces of which are coated with an active refractory metal oxide by dipping so that the weight of oxide deposited on the surface is (preferably) 5-30% by weight of that of the structure. Suitable oxides are active or calcined alumina, baryllia, magnesia, thoria or silica. A coating of a low ignition oxidation catalyst is applied over the oxide, e. g. by dipping in an aqueous solution of an inorganic salt of a platinum group metal, precipitating the metal as an oxide and activating by heating to 100-1100 C. in a reducing atmosphere. In a modification, the support plate 7 has a single aperture and a single tube which contains four 90 degrees-sector shaped catalyst blocks, the plane faces of the blocks being separated by resilient spacers. A cruciform-shaped gas flow barrier plate is tack-welded to the downstream end of the tube, so that it covers the ends of the gaps between the blocks.

Filed: 1970-03-16
Abstract: 1314981 Moulding electrical connectors BURNDY CORP 16 March 1970 12504/70 Heading B5A [Also in Divisions D1 and H2] The invention relates to a two-stage crimping die assembly for a tubular metal connector surrounded by a plastic sleeve. The metal connector, Fig. 7, is of the kind having a terminal 10 and a crimp barrel 11 that is inserted into the plastic sleeve 12, Fig. 8. The sleeve 12 projects in the form of a shroud 19 rearwardly of the barrel 11 away from the terminal 10. An insulated cable, having a bared end 18, is then inserted into the connector such that the bared end 18 is in the crimp barrel 11 and the sheath 17 of the cable is in the shroud 19. The two-stage die, described below, then crimps the connector and the sleeve on to the cable as in Fig. 9, the die being such that the plastic sleeve develops at least one ridge 50, 55 on its outer surface to prevent excessive extrusion of the plastic sleeve 12 out of the die during the compressing operation. The die, Fig. 2, has a fixed lower part composed of a barrel crimping portion 22 and a shroud crimping portion 21. The upper part of the die is mounted on a piston P and descends through a fixed housing 70, 71. It comprises a barrel crimping part 38 that is rigid with the piston P and a shroud crimping part 40, 62 that is biased downwardly by a spring 75. A pin 77 limits the lower setting of the shroud crimping part 40, 62 and an axially displaceable bar 85 limits the upper setting of the shroud crimping part 40, 62, the bar 85 being of stepped formation to permit selection as to the effective thickness of the bar. The barrel crimping parts of the die are formed with grooves 26, 28, 37, 39, Fig. 5, that co-operate to form annular channels into which the plastic sleeve 12 can flow during the crimping process and so prevent excessive extrusion of the plastic sleeve 12 from the die. Due to the spring 75, the shroud crimping portion 40, 62 is effective first but exerts very little effective pressure. Thereafter the barrel crimping part 38 is effective to crimp the connector on to the cable, the shroud crimping portion 40, 62 being then also effective by an amount determined by the setting of the bar 85. The shroud crimping surface 40 is of conical shape, Fig. 5, such that the plastic sleeve 12 will tend to be extruded into the channels 26, 28, 37, 39 rather than be extruded from the die. When the die is opened the spring 75 ejects the completed connector from the upper die.

Filed: 1970-12-08
Abstract: 1319510 Marine propulsion A P PEDRICK 8 Dec 1970 58201/70 Heading B7V In a marine propulsion unit of the same general form as that described in Specifications 997,738, 1,066,049 and 1,066,050, a flash distillation process is employed to obviate saltscaling. The propulsion unit is a jet-propulsion unit in which the jet is produced by stream derived from boiling the water through which the associated ship is to be propelled, a pump being driven by the same steam and the water to be boiled being delivered to the boiler by this pump. To prevent salt-scaling, salt water entering the propulsion tube at one end, 2, is impelled by the pump 4 to enter a plurality of smaller tubes 7 which are in heat-exchange relationship with the indicated flow path from and to the heat source via the pipes 11 and 12. The tubes 7 have fine nozzles 10 at their outlet ends, and the effect is stated to be that water under pressure at a temperature above 100‹ C. is the only medium in any of the pipes and tubes. On emerging from the nozzles, however, boiling takes place immediately, producing the required steam jet. Any precipitation of salt scale at this stage is carried away by the steam jets. As they emerge, the jets impinge on turbine blades 6 which drive the pump 4. The propulsion unit may be applied to a variety of marine craft some examples of which are depicted in Figs. 2 to 8 (not shown).
