Patent GB-765511-A (GB)
Title: N-butyl-3-phenylsalicylamides
IPC: C07C233/12
Filed: 1955-01-19
Abstract: The invention comprises N-butyl-, N-(n-butyl) and N-primary isobutyl-3-phenylsalicylamides and a process for the preparation of such compounds which comprises bringing together the appropriate butylamine and a lower alkyl or aryl ester or acid halide of 3-phenylsalicylic acid wherein the lower alkyl radical contains one to eight carbon atoms inclusive.  Starting materials mentioned include alkyl esters from ethyl to hexyl and phenyl, tolyl, cresyl esters of 3-phenylsalicylic acid and 3-phenylsalicyl chloride, bromide and iodide.  Where a 3-phenylsalicylyl halide is employed as starting material, the crude reaction product obtained by reacting 3-phenylsalicylic acid with thionyl halide or other acid halide-forming agent is suitable.  In examples: N-(n - butyl) - 3 - phenylsalicylamide is obtained by reacting methyl 3-phenylsalicylate and n-butylamine (1); N-primary isobutyl-3-phenylsalicylamide is obtained by reacting phenyl 3-phenylsalicylate with isobutylamine (2); N-(n - butyl) - 3 - phenylsalicylamide is obtained by treating 3-phenylsalicylic acid with thionyl chloride in benzene and reacting the product with n-butylamine whilst secondary and tertiary butylamines may be employed in similar processes to obtain N-(secondary butyl)- and N-tertiary butyl-3-phenylsalicylamides.

Inventor: WILLANS GEORGE HERBERT
IPC: F22D1/42
Filed: 1916-02-03
Abstract: 103,534. Willans, G. H., and Luard, E. S. Feb. 3, 1916. Tubes, water.-In a combined feed-water heating and boiler water-circulating apparatus for locomotive and other boilers, the water outlet is controlled by a valve formed with relief passages, so that when the valve is closed to cut off the flow of water into the boiler, the relief passages place the heater in communication with the atmosphere. The valve 36 is shown applied to the heating and circulating apparatus described in Specification 4085/15. When the valve head 42 is screwed down on to the end of the boiler inlet pipe 35, the heater is open to a relief pipe 46 through radial passages 52, 53, and a longitudinal passage 50 in the valve stem. When the valve is open, the head is seated against the bottom of the valve casing 41. The outlet end of the relief pipe is carried to a position where it is visible to the engine driver.

Title: Improvements in or relating to collapsible cores for casting concrete or the like
IPC: B28B7/30
Filed: 1948-01-22
Abstract: 647,412. Casting in situ. KING, V. R. Jan. 22, 1948, No. 1965. [Class 20(ii) A collapsable core for use in forming concrete cavity walls, sewers or chimney stacks comprises a hollow shell having flexible arcuate members X and flat plates MP each connected together by a slotted tubular member TS which engages over flanges FH. The members TS have holes to receive a frame SF. To collapse the core, the members TS on one side of the core are raised while those on the other side are held fixed, the frame SF thus pivots out of a horizontal plane and draws the members TS together as shown in the upper part of the Figure. Tie members are shaped to engage between the cores. Cores may be used side by side and end to end. Members RL help to support the inward pressure of the concrete. In a modification, the transverse rods of the frame SF may be replaced by plates which have holes to receive the longitudinal rods. The edges of the plates abut against the plates MP. Specification 642,404 is referred to.

Abstract: 787,218. Respiratory appliances. SPIROTECHNIQUE. Jan. 25, 1956 [Feb. 7, 1955], No. 2481/56. Class 81 (2). Respiratory apparatus particularly for divers, comprises a regulator consisting of a casing 10, Fig. 1, having a valve box 32 connected to, e.g. a compressed air bottle and the flow through which is controlled by a valve member connected to a diaphragm 14, the upper face of which is subject to the water pressure through apertures in the casing wall, while the lower face is exposed to the pressure in a conduit 23 connected to one end of a T-fitting 24 having a mouthpiece 90 into which the jet of air is directed by the mouth of the conduit 80. The other end of the fitting 24 is connected by a conduit 26 to a duck bill exhaust valve. In operation, when the diver inhales, suction is produced in the conduit 23 resulting in the downward flexing of the diaphragm 14 and opening of the valve, so that air flows through the conduit 80 and issues as a jet into the mouthpiece. The jet increases the suction in the pipe 23 and thus the opening of the valve. The exhaled air passes through the conduit 26 to the exhaust valve, the exhaust being communicated to the lower face of the diaphragm through the conduit 23.

Title: Variable speed gear for motor vehicles
IPC: F16H37/08
Filed: 1923-01-29
Abstract: 209,305. Ephgrave, G. H. Jan. 29,1923. Variable-speed gearing comprises a spur epicyclic train D, E, F controlled through a worm pair S, R and disc-and-roller gearing O, L with provision for a direct drive through a friction clutch B<2>. For the variable speeds, the driving- shaft A is connected by a clutch B' to a gear M driving the disc L, and also through a sleeve C to the sun gear D. The friction gear causes the planet carrier G to yield, so that the internal gear F is driven fastest when the worm pair is locked. By the side of the epicyclic train is a similar train F, E', H to reverse the motion a second time, and drive the gear H and with it the shaft I in the same direction as the shaft A is turning, so permitting of the use of the direct-drive clutch. Reversed driving is effected by causing the train H, E', F to turn solid by releasing a brake K and closing a clutch T, the carrier G being locked by the worm pair. A reducing-train may be interposed between the elements S, G.
