IPC: C04B7/60
Abstract: 132,855. Auden, A. C. Sept. 23, 1918. Potassium salts.-Minerals such as feldspar, mica, micaceous schist, muscovite, pegmatite, China-stone, glauconite, and zeolites such as those found in a basalt matrix, are mixed with lime and salt, ground, and roasted at 900-1000‹ C. for such a time that a small proportion of " dead lumps " are formed. The charge is spread out to cool and raked with wooden rakes. The cooled material is sifted, the " dead-lumps " being then ground and treated again, while the fine material is leached in hot water, but when glauconite or the like is employed, the leaching is performed in an autoclave, steam being admitted until the temperature rises to 200-205‹ C. The evaporation of the solution is preferably effected in two evaporators in series when glauconite is employed, the first producing phosphate and the second chloride. The residue is mixed with ground, preferably unslaked lime, and preferably with a small quantity of alum or aluminium sulphate, kneaded, dried, and the heat gradually brought up to 1100‹ C., the mass being firmly but not too tightly packed in the furnace. The mass is spread out to cool, raked with wooden rakes, sifted, and the coarse material ground. The product is white cement, but is somewhat sensitive and is therefore mixed with a small quantity of ground gypsum, the mixture being spread on a floor, left for about a week, and then turned and mixed. Specification 21697/11 is referred to.

Title: Temperature compensated gas storage systems
IPC: F17C5/00
Filed: 1971-05-05
Abstract: 1335254 Gas storage systems R W MCJONES 5 May 1971 [6 May 1970] 13365/71 Heading F4P A process for charging a predetermined quantity of gas into a container 78 containing less than said predetermined quantity regardless of container temperature comprises the steps of (a) sensing the pressure differential between the container 78 and a predetermined quantity of reference gas contained in a reference vessel 132 and having substantially the same temperature and pressure characteristics as the gas to be charged into the container 78; (b) in response to the pressure differential charging the gas into the container 78 under a condition where the reference vessel 132 is in thermal communication with container 78 so that the reference gas temperature is substantially the same as the container gas temperature; and (c) terminating charging of the gas into container 78 when a predetermined pressure differential is reached. As shown, the vessel 132 is a bellows located in a body 128 suspended from a valve housing 80 via a tube 86, a spring-biased valve member 96 being located in housing 80 into which a passage 104 leads from a gas source. Located in the passage 84 connecting housings 80 and 128 is a rod 120 which contacts bellows plate 140 and valve member 96. Thus, in operation, the pressure differential between the container 78, which communicates with the exterior of bellows 132 via parts 126 and passage 84, the interior of bellows 132 determines the position of plate 140 and rod 120. If the pressure inside bellows 132 is greater than that of container 78, the plate 140 and rod 120 push the valve 96 away from its seat and charging from passage 104 to container 78 takes place. When the pressure in container 78 reaches a predetermined value relative to bellows 132 the plate 140 and rod 120 have been lowered sufficiently to permit the valve member 96 to close against its seat thus terminating charging. If gas is drawn via line 114 from container 78, the bellows plate will again rise to open, via rod 120, valve member 96. The reference gas can alternatively be stored in a closed chamber having a piston defining one of the chamber walls and connected by rod 120 to valve member 96 (Fig. 3, not shown). In a further embodiment, a free piston slidably received in a cylinder connected to a reference vessel, which vessel is outside the container but in thermal communication therewith, acts as both a differential pressure sensing means and valve means (Fig. 4, not shown).

Abstract: 850,678. Radiation-detecting apparatus. SIEMENS-REINIGER WERKE A. G. April 24, 1959 [April 26, 1958], No. 14169/59. Class 98(1) Apparatus for measuring and recording the intensity distribution of radiation emanating from radioactive isotopes by linear scanning comprises a first horizontally displaceable carriage 6, a second carriage 7 carried by said first carriage and horizontally displaceable in a direction at right-angles to that of the first carriage, a support 4 having at least two parallel pivotal axes, one end of the support being fixed to a table 3 supporting the whole apparatus, and the other end carrying a radiation-measuring head 5, means for coupling the measuring head to either the first or second carriage, means for disposing the head so that it can scan in either a vertical or a horizontal plane, and means for vertically displacing the first carriage 6 synchronously with the displacement of the second carriage 7. In Fig. 1 the apparatus is set up for the measuring head 5 to scan the horizontal area 8. The scanning is carried out as the carriage 6 traverses horizontally, since carriage 6 carries carriage 7 to which the head 5 is linked by a pin 13. At the end of each line the head 5 is moved at right-angles for the width of one scanning line by actuating carriage 7. At the other end of carriage 7 is a recording head 9 which traverses a recording surface 10. For scanning a vertical surface 12, Fig. 2, the head 5 is disconnected from carriage 7 by removing pin 13, swung into a horizontal position, and connected by a fork to carriage 6. The scanning is carried out as before, by horizontal traverse of the carriage 6. However, movement from one scanning line to the next must now be effected by a vertical movement of head 5, and this is carried out by movement of the whole supporting table 3 on a vertical pole 2. The carriage 7 is moved synchronously to give a corresponding movement of head 9 on the recording surface 10.
