Title: Improvements in or relating to methods of preparing compounds of phenolphthalein and the improved compounds produced thereby
IPC: C09B11/08
Filed: 1940-06-08
Abstract: 542,441. Phenolphthalein glycosides. BRISTOL-MYERS CO. June 8, 1940, No. 10057. Convention date, Aug. 19, 1939. [Class 2 (iii)] [Also in Group VI] Phenolphthalein glycosides are prepared by re-acting phenolphthalein with an acyl-halomono-saccharide in the presence of a re-agent to remove halogen and hydrolysing the product to remove acyl group. The sugars capable of use in the present invention include trioses, tetroses, pentoses, methyl pentoses, hexoses and also the lower reducing polysaccharide sugars having two, three or four mono-saccharide components. The preferred procedure according to the invention is to convert the desired sugar into its acyl derivative, treat this with hydrogen bromide. to form the acyl bromo-compound and then re-act this with phenolphthalein. The preferred acyl component is acetyl, but other acyl groups particularly those of the lower fatty acids such as formic and propionic are very suitable. Chlorine may be substituted for bromine in making the halocompound, but the chlorine compounds are not so re-active as the bromo-compounds. In an example glucose is acetylated with acetic anhydride, and the pentacetate treated with hydrobromic acid in glacial acetic acid solution to give acetobromglucose. To re-act this compound with phenolphthalein it is added in dioxane-chloroform solution to a mixture of phenolphthalein and quinoline. Silver oxide is added to the re-action mixture in several stages to act as the halogen removal agent. Alternatively the dioxane and quinoline may be omitted, and a suitable drying agent added. The acetylated compound is hydrolysed by heating with sodium methylate in methyl alcohol solution. In a second example, galactose is substituted for an equal weight of glucose under the same re-action conditions to give phenolphthalein di-beta-galactoside. It is stated that the di-glycosides of phenolphthalein although not all equally soluble in water are sufficiently soluble to permit of being compounded into aqueous concentrates or elixirs of sufficient strength that one or two teaspoonfuls of elixir contain sufficient dose as a laxative.

Title: Improvements relating to loading apparatus on motor vehicles
IPC: B66C13/18
Filed: 1944-05-26
Abstract: 579,545. Vehicle fittings for loading. DAY, H. O. May 26, 1944, No. 10 250. Convention date, May 26,1943. [Classes 78 (iii) and 78 (iv)] In apparatus for unloading and loading vehicles the load is moved from the vehicle to the ground or vice versa by a boom 10, Fig. 1, which is swung about its pivots 16 by a main power unit comprising piston rods 20 operating in cylinders 18 and connected to the boom at 20d and an auxiliary power unit comprising piston rods 22 operating in cylinders 21 and connected to the boom by links 23. The pistons are operated by a fluid-pressure system, Fig. 6, comprising a reservoir 28, pump 29 driven from the vehicle engine and a master control valve 30 having a single control handle 50 for performing all phases of the normal working cycle of the boom, and an auxiliary hand-controlled valve 31 whereby the normal conditions can be modified to enable the boom to be moved only by one pair of cylinders and also whereby a slow and uniform lowering of the load may be effected. With the lever 50 in neutral position fluid is trapped in all cylinders and the boom locked in position. Before unloading operations commence, the valve 30 is so adjusted by moving the lever 50 to position F that fluid from the pump holds the piston rods 20 in their retracted positions whilst the piston rods 22 are extended. Any excess pressure which develops in the cylinders 18 is relieved by excess fluid passing through the valve chamber 67, port 68 and conduits 79 to the reservoir 28. The boom is now swung rearward by shifting the lever 50 to position B whereby the position of the valve 33 is such that pressure acts on the pistons 20a to move the rods 20 outwardly. To prevent sudden acceleration of the boom as it passes its dead centre position due to the stress upon the rods 20 changing from compression to tension, the valve 30 may be throttled until the boom reaches the position in Fig. 4 at which faces 25<11>, 26<11> on the boom engage corresponding faces 251, 261 on the link 23. Due to the throttling of the valve 30, the boom 10 slowly forces the piston rods 22 into their cylinders whereby its downward movement is effectively cushioned until it reaches the position shown in Fig. 5. The control lever 50 is now returned to its neutral position. More sensitive control of the lowering of the boom may be effected by operating the valve 31. When the boom is to be returned, the lever 50 is moved to position F whereby the piston rods 20 are retracted and simultaneously the piston rods 22 are extended. The rods 22 continue to assist the lifting of the boom until it reaches the position in Fig. 4 where the rods 20 will have attained a more favourable leverage. Undesired acceleration of the boom as it passes through its dead centre position is prevented by moving the lever 50 part way towards its neutral position to again throttle the valve. Springs 42, 43 on the valve 33 return the lever to its neutral position when released by the operator.
