Title: Improvements in vacuum brakes
IPC: B60T13/24
Filed: 1924-07-05
Abstract: 245,478. Dewandre, A. July 5, 1924. Addition to 226,670. Fluid-pressure; hand and foot action; force-transmitting mechanism. - In vacuum brakes for vehicles fitted with internal-combustion engines and of the kind described in the parent Specification, means are provided whereby, as in Specification 232,738. the braking effort exerted by the cylinder piston reacts upon the operating-pedal; whilst the control of the distributor is effected from the pedal through a system of rods and levers in such a manner that the distributor, after being moved to. one or other of its operative positions, is automatically returned to neutral position by the subsequent movement of the brake rigging. In the form shown in Fig. 1, the piston rod of the brake cylinder 8 is connected through members 11 - - 15 to a lever 16 mounted on a pin 17 carried by one of two levers 18 rigid with a rock-shaft 19, connections 20, 21 leading to the blakes being provided on the levers 18. Rods 24, 25 connect the lower ends of the levers 16, 18 to a lever 23 keyed on the pedal shaft, the rod 24 being pivoted directly on a pin 28 carried by the lever 23, and the head of the rod 25 being provided with an elongated slot 26, Fig. 3, a regulating screw 40 in which is normally engaged by the pin 28. Freely mounted on a cylindrical extension of the head of the rod 25 is an arm 33, a slot 36 in which is engaged by a square boss 35 on a pin 34 carried by the lever 23, and the upper end of which is connected by the rods and levers shown to the distributor 4, which is connected by pipes 2, 9 respectively to the suction pipe of the engine and the brake cylinder. With this arrangement, the initial movement of the pedal 22 rocks the lever 23 without moving the rod 25, as the pin 28 moves rearwardly in the slot 26. The arm 33, however, is at once rocked by the pin 34 to operate the distributor, and when the brakes are thus applied, the braking effort transmitted to the lever 16 reacts through the rod 24 and lever 23 on the brake pedal. The movement of the lever 18 will so move the rod 25 as to rock the lever 33 about the pin 34, now stationary, to return the distributor to neutral position, unless the pedal is further depressed. If the movement of the pedal is such that the pin 28 moves to the rear of the slot 26, the brakes will be applied also bv foot pressure. In a modification, Fig. 5, the cable 11 from the brake piston acts on a lever 40 pivoted on a lever 41 connected at 45 to the brakes, and the braking pressure reacts on an extension 42 of the pedal 44 by means of the upper end of the lever 40. In this arrangement, the distributor is operated by a rod 49 acting on a lever 46 pivoting about a pin 52 carried by a lever 47 connected to the lever 41, the lever 47 being operated by the pedal only when a pin 50 carried by it is engaged by the rear end of a slot 51 in the lever 46.

Title: Improvements in or relating to the production of 3-4-di(aminomethyl)-5-amino-6-methyl pyridine and to the production of vitamin b therefrom
IPC: C07D213/73
Filed: 1942-11-20
Abstract: 3,4 - Di - (aminomethyl) - 5 - amino - 6 - methyl pyridine, which on deamination (replacement of -NH2 by -OH) yields vitamin B6, is prepared by reducing 2 - halo - 3,4 - dicyano - 5 - amino - 6 - methyl pyridine.  An ester of 3-cyano-4-carboxy - 6 methyl - pyridone - 2 is reacted with ammonia to form the amide, this is dehydrated to 3,4-dicyano-6-methyl-pyridone-2, the latter nitrated to yield the 5-nitro derivative which on halogenation gives 2 - halo - 3,4 - dicyano - 5 - nitro-6-methyl-pyridine yielding on reduction first the corresponding 5-amino compound and then 3,4 - di - (aminomethyl) - 5 - amino - 6 - methyl pyridine.  Deamination gives vitamin B6-3,4 - di - (hydroxymethyl) - 5 - hydroxy - 6 - methyl pyridine.  In an example, the ethyl ester of 3 - cyano - 4 - carboxy - 6 - methyl - pyridine - 2 is added to methanol saturated with ammonia at 0 DEG C., and the amide isolated by concentrating in vacuo.  Other alkyl, aromatic or aralkyl esters may be used, or esters derived from cycloaliphatic, heterocyclic or nitro alcohols, e.g. 2-nitro-2-methyl-1-propanol.  Dehydration of the amide is effected with phosphorus oxychloride at 145-150 DEG  C. or, in the presence of toluene, at a lower temperature.  Other dehydrating agents and solvents may be used.  The dicyano compound is nitrated in acetic anhydride at 45-52 DEG  C. with fuming nitric acid and a little urea. Halogenation is effected with PCl5 in chlorbenzene at 135 DEG  C. Other halogenating agents, e.g. PBr5 may be used.  Reduction of the nitro group is carried out with hydrogen using platinum oxide as catalyst and acetic anhydride as solvent.  Other catalysts or acid and metals or alkaline reduction may, however, be employed.  A solution of the 2-chlor - 3,4 - dicyano - 5 - amino - 6 - methyl pyridine and HCl in aqueous methanol is added to a methanol suspension of reduced palladium chloride while absorbing hydrogen at 30 DEG  C.  The trihydrochloride of 3,4-di-(aminomethyl)-5-amino-6-methyl pyridine is obtained.  Using HBr, the trihydrobromide can be obtained similarly.  An aqueous solution of the hydrochloride is added with NaNO2 solution to hot hydrochloric acid, the product evaporated to dryness in vacuo, and extracted with acetone.  The residue is extracted with ethanol and the extract worked up to isolate vitamin B6.  Other nitrites, e.g. KNO2, or amyl nitrite may alternatively be used.
