Title: Carbamic acid esters
IPC: C07C271/06
Filed: 1961-09-11
Abstract: The invention comprises 1,3-propanediol dicarbamates of the formula:- <FORM:0934207/IV(a)/1> wherein R1 represents a C7-8 cycloaliphatic radical or an alkyl radical substituted by a cycloaliphatic hydrocarbon radical, and R2 represents an alkyl radical (preferably a C1-7 alkyl radical), a cycloaliphatic radical or an alkyl radical which is substituted by a cycloaliphatic hydrocarbon radical.  The above compounds are prepared by reacting a diol of the formula:- <FORM:0934207/IV(a)/2> with an alkali metal isocyanate in the presence of a mineral acid.  Diols of the above formula are prepared by lithium aluminium hydride reduction of appropriate dialkyl-a -R1-a -R2-malonic acid esters.  1,3-Propanediol dicarbamates of the above general formula may be incorporated into pharmaceutical compositions having a pronounced tranquillising effect accompanied by a minor sedative and a mild muscle relaxing action.  The pharmaceutical compositions may be used for enteral (e.g. oral) or parenteral administration and may take the form of tablets, dragees, capsules, suspensions, solutions or emulsions.

Patent GB-827376-A (GB)
Title: Improvements in the manufacture of isocyanates
Filed: 1956-03-12
Abstract: The invention comprises a process for the continuous preparation of aromatic isocyanates by the reaction of an amine or a salt easily decomposible into a free amine, in an inert solvent, and a solution of phosgene in excess which is injected under a pressure greater than 3 kgs. per sq. cm., by introducing the reactants simultaneously with vigorous mixing into the lower end of a tubular reactor, in which the reaction products are caused to move rapidly to the upper end, and the whole of the liquid phase is collected in a container from which it passes for the isocyanate to be extracted.  The latter container is kept under pressure and the excess phosgene evolved, together with the hydrochloric acid formed, passes to and through a condenser, and the phosgene is liquefied by cooling with water.  The reaction mixture in the container flows to a further heated container where the pressure is reduced so that the mixture expands, and then flows out preferably as a film, the remaining excess phosgene and hydrochloric acid being released and condensed.  The excess phosgene may be recycled.  Examples are given of the preparation of tolylene diisocyanate fron tolylene diamine and phosgene intricresyl phosphate, and the preparation of benzene isocyanate, from aniline and phosgene in ethyl phthalate.

[Also in Group XXXVI] An accumulator lid is provided with depressions 5, 6 which are formed with slots 7, 8 to receive the plate lugs which may be melted down to form connecting bars lying in the depressions 5, 6. Alternatively a toothed plate 31 as shown in Fig. 7, or a plate provided with slots, may be moulded into each of the depressions 5, 6. The plate lugs are then passed through the slots 7, 8 in the cover and through the slots or between the teeth of the plate 31 which is then melted down to form a connecting bar joining the lugs together. The plates 31 need not be moulded in the cover but may be placed loosely in the depressions and melted to connect the plate lugs. In another method molten metal is poured into the depressions 5, 6 to connect the plate lugs. A terminal post 18 having an extension 20 is moulded in the cover and is provided with an integral connecting-bar 21 which becomes united with the melted metal in the corresponding depression. Adjacent cells of a battery are joined together by U-shaped connectors which straddle the partitions between the cells and are burned to the bars in the depressions in the covers.

As shown a condenser or other component of a wireless set is secured to the panel by the sheet-metal members 3 each attached rigidly at one end to the component by a rivet 4, rotation being prevented by a lug 5 extending into an aperture 6 in the component. Notches 10 on the legs may engage directly with a hole in the panel when an earthing connection is required, or as shown insulating bushes 11, 12 with washers 14, 15 may be inserted in the hole 13 in the panel and the securing member 3 passed through a central aperture of the bush to make a snap-fastening engagement with the washer 15, thus holding the parts together. The members 3 may be secured to the panel and resiliently engage the component, and may have lateral lugs engaging grooves in the component to prevent rotation. The notches 10 may be curved so that the parts may be separated by a direct axial pull. The Specification as open to inspection under Sect. 91 comprises also a form in which lateral lugs on the legs engage the face of the supporting structure.
