Title: Improvements in and relating to coupling vehicles
IPC: B60D1/40
Filed: 1920-09-23
Abstract: 176,029. Marks, E. C. B., (Ohio Motor Vehicle Co.). Sept. 23, 1920. Couplings for tractors and road vehicles.-To facilitate coupling, the vehicles are temporarily connected by a pivoted link so that the coupling members are guid.ed into co-operating relation by the approach of the vehicles towards one another. The temporary connection consists of a link 23, 24 hinged permanently to the tractor 1 and having a pin 31 adapted to engage temporarily a hole in the end of an arm 34 carried by the trailer 2. The link serves to guide the vehicles as they approach to ensure .engagement automatically of the eye 3 on the track with the pivoted hook 4 on the tractor. When the vehicles have been coupled and the link 23, 24 is therefore lying across the end of the tractor 1, it drops a short distance so that the pin 31 automatically disengages and the link is then locked in position. This is effected by making the link movable vertically in its bearings 21, 22, and providing a foot 38 which bears upon the upper bearing 21 and holds the link raised in all positions except when it is disposed transversely.

Title: Bromination of steroids
IPC: C07J5/00
Filed: 1962-07-17
Abstract: Isolated double bonds of androstane and pregnane compounds are brominated by treatment of the steroid with at least one molar equivalent of bromine at -10 DEG  to 0 DEG  C. in an inert solvent and in the presence of a catalytic amount of an amine.  The steroid may, for example, contain a D 2-, D 5-, D 7-, D 9 (11)- or D 14 (15)-double bond to be brominated, but double bonds conjugated with keto groups, e.g. D 16 in 20-keto-pregnanes, generally remain unattached.  The preferred starting materials are D 5-3b -ols which yield 5a ,6b -dibromo-compounds, bromination at other positions of the steroid molecule being inhibited.  A slight excess of bromine is preferably used, and suitable amines are alkylamines, dialkylamines, pyridine, piperidine, collidines and lutidines. Suitable solvents are halogenated hydrocarbons and saturated cyclic ethers.  In Examples (1) and (3) D 5-pregnen-3b -ol-20-one is brominated, the dibromo product is oxidized with chromic acid, the resulting 3-ketone is debrominated with zinc and the thus obtained D 5-pregnane-3,20-dione is treated with acid to give progesterone; (2) D 5- androsten - 3b  - ol - 17 - one is similarly converted to D 4-androstene-3,17-dione; (4) D 5,16 - pregnadien - 3b -ol - 20 - one is brominated to 5a ,6b -dibromo-D 16-pregnen-3b -ol-20-one which by the method of (1) yields D 4,16-pregnadiene-3, 20-dione; and (5) and (6) D 4,9(11) pregnadiene-3, 20-dione is brominated 9a ,11b -dibromoprogesterone.

Abstract: 902,624. Making gas from solid fuel. STEINMULLER G.m.b.H., L. & C., and STEINKOHLEN-ELEKTRIZITAT-A.G. Aug. 26, 1958, No. 27410/58. Drawings to Specification. Class 55 (1). In a process for extracting gas from solid fuel in which finely-ground solid fuel and an oxidizing agent are fed along the axis of a cylindrical degasification chamber, the amount of oxidizing agent is sufficient to oxidize the surface of the particles of fuel in a first reaction zone of the chamber and a hot carrier gas is supplied to the chamber tangentially so as to cause the partially oxidized fuel to flow to a second reaction zone wherein degasification occurs. Preferably the oxidizing agent and fuel are mixed together before entering the degasification chamber. The carrier gas and/or the oxidizing gas may be heated to a temperature above 1000‹ C. before entering the degasification chamber. If desired, the fuel may be allowed to derive heat from the oxidizing gas before entering the chamber. The oxidizing gas may be air, oxygen-enriched air or oxygen. The carrier gas may be super-heated steam which on contact with incandescent particles of fuel decomposes and thus provides oxygen for surface oxidation of the fuel.
