Title: Pressure-sensitive recording material
IPC: B41M5/165
Filed: 1974-10-15
Abstract: 1450605 Pressure-sensitive recording material NCR CORP 15 Oct 1974 [31 Oct 1973] 44565/74 Heading D2B A pressure-sensitive recording material comprises microcapsules containing a colourless, electron-donating, colour-forming material dissolved in a first solvent, a solid electron-accepting, polymeric colour developing material, and microcapsules containing a second solvent miscible with the first solvent, the solvents being such that the first solvent has a weak affinity, and the second solvent a strong affinity to the colour developer. The components may be carried on a single sheet or separate supporting sheets. The colour developer may also be microencapsulated. By "a solvent having a weak affinity to the colour developer" is meant a solvent which, when having a colour forming material dissolved therein, is brought into contact with the colour developer, does not give rise to significant colour formation, whereas "a solvent having a strong affinity to the colour developer" causes intense colouration. Intensity of colour may be measured in terms of Typewriter Intensity Index (TI) values, solvents having a TI value less than 55 being those having a strong affinity, and those having a TI value more than 65 being those having a weak affinity. Specified solvents having weak affinity include castor oil, esters of trimellitic acid, chlorinated paraffin, esters of phthalic acid, diphenyl ether, diisopropyl naphthalene, hydrogenated terphenyl, and mixtures thereof. Exemplified solvents having strong affinity include diamylmethanes, diarylethanes, monoisopropyl naphthalene, esters of maleic acid, triaryldimethanes, C 1-4  alkyl diphenyls and mixtures thereof. Conventional colour-forming materials and polymeric colour developers may be used. A low viscosity solvent for regulating viscosity may be added to either of the above solvents.

Abstract: 1,190,940. Loading and unloading. CHARROLD Ltd. 8 Jan., 1969 [3 Nov., 1967], No. 45047/67. Heading B8E. [Also in Division Gl] The vehicle shown in Specification 825,405 has the counter that is operable by the elevating mechanism for a filled sack, replaced or supplemented by a time recorder arranged in an electric circuit which also includes a switch adapted to be operated each time the control lever for the conveyer is operated. The conveyer is hydraulically driven and controlled by a lever. When the lever is operated pressure is increased in the hydraulic circuit and a pressure responsive switch completes the recorder circuit. Alternatively the lever acts directly on a microswitch in the recorder circuit. Thus each filling and weighing operation is recorded in each delivery and the interval between deliveries to different customers can also be ascertained from the continuous operation of the recorder, which has a tamper-proof casing.

Patent GB-928635-A (GB)
Title: Separation of conjugated bile acids
Inventor: ANTONIDES HAROLD JAMES
Filed: 1961-12-21
Abstract: Conjugated bile acids are separated by acidifying the bile material, adding an aqueous solution of a salt containing trivalent metallic cations in amounts sufficient to render insoluble the glycine conjugated bile acids and separating these from the taurine conjugated bile acids which remain in solution. Preferably the bile material is first adjusted to a pH of between 10 and 12, for example with sodium hydroxide, zinc sulphate solution is added, the pH is readjusted to 7.5, for example with a mineral acid, the mixture is separated, e.g. by filtration, and the filtrate is mixed with a solution of a halide, nitrate, acetate or sulphate of trivalent aluminium, iron or chromium.  The mixture may then be separated, e.g. by filtration or centrifugation, purified glycocholic acid prepared from the precipitate by raising the pH of the complex to split it and give soluble glycocholic acid, and the filtrate containing taurocholic acid and water soluble salts concentrated and dried, slurried with an alcohol, the slurry filtered and the filtrate dried to give taurocholic acid.

Abstract: 1,070,198. Heated reaction vessels. N. KODAIRA and M. MOTEGI. Nov. 18, 1964, No. 46889/64. Heading B1X. [Also in Division F4] In a vapour heating apparatus the reaction chamber 5, in which the material to be heated is placed, is surrounded by a closed vessel 1 which is itself covered with a heat insulating material 11 and which contains an electric heating element 4 for heating a liquid 3. The vapour generated fills the vapour chamber 2 and any low boiling point impurities, such as water, in the liquid 3 forms in its vaporised state a layer at the top of the chamber 2. To prevent the layer having an adverse effect on the temperature and heat transfer to the heating chamber 5 it is discharged through a pipe 7 by opening a valve 8 and passing it into a condensing vessel 9 where the liquid is left to stand to allow separation of the water from the heating liquid. The water is then removed from the top of the vessel 9 and valve 8' is opened to allow the heating liquid to pass into the bottom of the closed vessel 1. This operation may be repeated until the water is completely removed. The temperature of the closed vessel 1 is controlled by a pressure sensing bellows 6 which switches the heating element on and off as required. The valve 8 may be replaced by a bellows operated valve placed inside the closed vessel controlling the flow through the pipe 7, and another pipe may lead from the top of the closed vessel 1 for filling the vessel with the heating liquid 3, and discharging air and impurites at the beginning of the heating operation.
