Patent GB-770542-A (GB)
Title: Improvements in or relating to the proparation of hecogenin
Inventor: SPENSLEY PHILIP CALVERT
IPC: A61K36/896
Filed: 1954-06-15
Abstract: Hecogenin is separated from a water-insoluble concentrate containing it and obtained by fermentation of the juice of the sisal plant by extraction of the concentrate with an aliphatic alcohol containing not more than four carbon atoms, heating the alcoholic extract with caustic alkali for a time sufficient to digest the coloured impurities taken up in the extract, and then precipitating hecogenin by means of water.  The alcoholic extract is preferably concentrated prior to the alkali treatment until the concentration of the tottl extracted matter represents 10-35 per cent of the whole extract and then treated with caustic potash or soda (in proportion of about 0.2-1.0 to 1 part by weight of extracted material) preferably in aqueous or aqueous-alcoholic solution forming a 4-20 per cent solution of alkali.  The aliphatic alcohol may contain up to 20 per cent water to increase the selectivity of the alcoholic extraction. In examples: (1) a powdered hecogenin concentrate is continuously extracted with boiling ethanol or methanol, the extract concentrated and refluxed with aqueous-alcoholic potassium hydroxide, the excess alcohol removed by steam-distillation and the precipitation hecogenin washed with hot water and dried; (2) (large-scale operation) a hecogenin concentrate is extracted as before, using aqueous ethanol, extract concentrated, solid potassium hydroxide added, mixture refluxed and then partially steam-distilled; hecogenin is then precipitated from the alcoholic residue by the addition of water, and purified by acetylation and crystallization. Specification 728,961 is referred to.

Filed: 1958-06-02
Abstract: 845,154. Focal viewing. HAZLETINE CORPORATION. June 2, 1958 [June 21, 1957], No. 17529/58. Class 40(3). The calibration of control devices 22, 23, 24 in the red, green and blue channels respectively of an electronic previewer in which signals representative of the latter colour components of a transparency 10 scanned by a flying-spot scanning tube 14 and co-operating optical and photoelectric devices 16 - 20 are supplied, in a processing circuit 21 which simulates the effects of conventional photographic printing techniques (e.g. spectral overlap and gamma characteristics), to a picture reproducing tube 12, is adjusted by visually comparing the image 13 reproduced by tube 12 with an optically projected image 32 of a positive transparency 31 produced by conventional photographic techniques from the transparency 10 (as depicted in the block 34) and then adjusting the resistances 25, 26, 27 until the image 13 is similar to image 32, the control devices 22, 23, 24 being previously set at a reference position corresponding to the densities of the filters 37 R; G; B; employed in the photographic process. Since the control devices 22, 23, 24 are calibrated in terms of the densities of the filters employed in photographic processes the latter requirements may be read directly from the settings required to produce an acceptable image 13 when any transparency is employed in the position 10. A similar adjustment technique may be employed when it is required to adjust the operation of the processing circuit 21. Specification 841,125 is referred to.

Title: Improvements in and relating to machines for casting dental parts and the like
IPC: A61C13/20
Filed: 1925-07-09
Abstract: 263,892. Richmond, R. Y. July 9, 1025. Casting-apparatus for dental parts, leaves, jewellery, &c. of porcelain, &c. are controlled by the operation of a single valve 26 which is connected to steam, compressed air, or other fluid at 36, Fig. 2, to a vacuum tank at 42, and to the atmosphere at 43. When operated the valve first admits pressure by pipe 37 to a cylinder 1, Fig. 1, to press the investment ring 44 against the cap 19, then by pipe 41 exhausts the space 12 below the investment 46, and finally by pipe 38 admits pressure to the cap. The cross section of the piston is greater than that of the investment to avoid leakage at the asbestos washers 11, 22 and this may be made more certain by reducing the pressure to the cap 19 by a regulator 39 and gauge 40. For testing the regulator or working with a, wet pad 22 a cock 25 is closed. If desired, the vacuum may be dispensed with. The cap 19 has a. ball joint 16 to allow for irregularities in the ring 44.

Title: Improvements in the manufacture and production of valuable hydrocarbons by the cracking or destructive hydrogenation of carbonaceous materials
IPC: C10G47/00
Filed: 1934-06-18
Abstract: Asphalt face oils and liquid cracking and destructive hydrogenation products are treated prior to hydrogenation and cracking by the addition of such an amount of dilute acid, e.g. dilute sulphuric hydrochloric nitric acids (up to 10 per cent strength) or weak organic acids, e.g. formic, acetic or sulphonic acids that the nitrogen bases, e.g. quinoline contained therein are dissolved but that the unsaturated constituents are not attacked, the acid solution being then separated.  The amount of acid required may be ascertained by preliminary experiment.  The subsequent cracking or destructive hydrogenation is carried out by heating the purified oils to 400--600 DEG  C. and then passing them over catalysts, e.g. metals and their compounds of Groups 2--8 and particularly oxides, sulphides, and halides of the metals of Groups 5--8 or of copper, aluminium, tin, zinc and germanium.  The catalysts may be applied to carriers, 1 part middle oil distilled from petroleum and containing 0,5 per cent nitrogen in the form of quinoline bases is treated with 2 parts of 10 per cent hydrochloric acid whereby the bases are removed in the form of hydrochlorides The purified oil is then heated to 460 DEG  C., under hydrogen pressure of 200 atmospheres and passed over a catalyst comprising molybdic acid, zinc oxide and magnesia.  Over 80 per cent yield of benzines boiling up to 180 DEG  C. and containing 33 per cent of constituents boiling below 100 DEG  C. is obtained.

Title: Apparatus for assessing the level of solid contaminants in hydraulic systems
Inventor: FUELL FREDERICK JAMES
IPC: F15B21/041
Filed: 1964-04-30
Abstract: 1,098,186. Testing hydraulic circuits. FAIREY ENGINEERING Ltd. April 29, 1965 [April 30, 1964], No.18018/64. Heading F1P. The level of contamination by solid particles of fluid in a hydraulic circuit is periodically assessed by passing the fluid during a predetermined time period through a fine elongated orifice 21 in a line 11 connecting the supply and return lines of the circuit, and detecting the pressure drop caused by silting of the orifice 21 by connecting opposite ends thereof by lines 35, 37 to opposite ends of a magnetic plunger 31 which when displaced against a biasing spring 36 and away from a red button 32 of magnetic material allows the latter to be projected by a spring 33 from its housing 29. The time interval, which is adjusted in accordance with the viscosity of the fluid, is that required for the fluid to pass from the supply end of line 11 through a line 61, the relatively coarse thread of a screw plug 43 and a line 62 to fill a cylinder space 48 whereupon the resulting pressure rise is transmitted through a line 60 to the underside of a magnetic plunger 55 and lifts it away from a green button 56 of magnetic material to allow the latter to be projected by a spring 57, from its housing. If the red button appears before the cylinder 48 is filled and hence before the green button appears the level of contamination is considered unduly high. In the event of the green button appearing first the test is considered finished and the red button is prevented from emerging by the green button. The succeeding test is initiated only after the orifice 21 has been freed of accumulated silt.

Title: Valve mechanism for fluids
Inventor: GIESLER JEAN VERDI
IPC: F16K11/24
Filed: 1955-06-23
Abstract: 798,298. Mixing fluids. ROBERTSHAWFULTON CONTROLS CO. June 23, 1955 [Sept. 8, 1954], No. 18204/55. Class 64(1) [Also in Group XXIX] Apparatus for mixing cold and hot water and maintaining a substantially constant flow to, e.g. a washing machine, comprises a casing 10 having cold and hot water inlets 28, 30 respectively, a preliminary mixing chamber 32, a final mixing chamber 34 and a mixed water outlet 16. Temperature - responsive flow control valves 80, 82 each comprising bi-metallic discs 86 bent about a diameter and secured by a single rivet 88 on the upstream side of a perforated member 84 are fitted in the inlet 28 and the chamber 32 respectively to control the flow of the cold and hot water to the chamber 32 in accordance with changes in their temperatures and a spring disc 108 secured by a single rivet 110 upstream of a perforated member 104 is fitted in the outlet 16 to control the flow of the mixed water in accordance with the pressure thereof. A non-return valve 96 is fitted between the inlet 30 and the valve 82. Communication between the preliminary mixing chamber 32 and the final mixing chamber 34 is controlled by a diaphragm shutoff valve 50 under the control of a solenoidactuated pilot valve 74 which when deenergized closed a passage 63 through the diaphragm so that the pressure of the water leaking into the space behind the diaphragm through a bleed opening 78 builds up to close the valve 50. On energizing the solenoid the passage 63 is opened to relieve this pressure and the valve 50 opens. If, e.g. the temperature of the cold water, is too high the discs 86 of the valve 80 flex to increase the flow of cold water relative to the hot water to maintain the temperature of the mixed water substantially constant. If on the other hand the temperature of the hot water is too high the discs 86 of the valve 82 flex to decrease the flow of hot water relative to the cold water. A diaphragm shut-off valve 52 similar to the valve 50 and under the control of a similar solenoid-acutated valve 74 controls communication between the hot water inlet 30 and the final mixing chamber 34 so that the washing machine may be supplied directly with hot water. An increase in pressure in the chamber 34 consequent upon an increase of flow of either cold or hot water causes the disc 108 to flex to decrease the flow through the outlet 16.
