Title: Method of extracting elements particularly the elements gold protactinium rhenium rhodium lanthanides and natural radioactive isotopes such as of uranium thorium and radium
IPC: C22B11/02
Filed: 1976-02-18
Abstract: 1489557 Metal recovery A BUMBALEK 18 Feb 1976 [10 Sept 1975] 6476/76 Heading ClA [Also in Division C7] Metals, particularly Au, Pa, Re, Rh, lanthanides, and natural radio-active isotopes of U, Th and Ra, are extracted by comminuting the meat and/or peel or skin of dried or raw fruit (preferably bananas), burning the fruit in an oxidizing atmosphere at 820-840‹ C., grinding the ashes so produced to a particle size below 40Á and processing the ashes to extract the elements. The method is particularly applicable to fruit grown on poor soil where the elements normally occurring in the fruit (Ca, Na, K, Mg, Fe) are replaced by the above metals. The recovery of the individual elements from the ashes is achieved by known methods, e.g. Au by treating with Cl 2 , and subsequently precipitating the gold chloride in solution, or by cyanide leaching; Pa by pentahalides; Rh by melting with KHSO 4 ; Re by means of potassium perrhenate, Th by reduction of ThO 2 , and Ra by conversion to an azide which is then decomposed.
Patent GB-307027-A (GB)
Title: Improvements in and relating to the heating of gases
IPC: C01C1/04
Filed: 1929-02-28
Abstract: 307,027. Gasverarbeitungsges. March 1, 1928, [Convention date]. Heating gases.-Hydrogen for use in catalytic reactions is heated by passage through a heat exchanger in counter current with an inert gas such as nitrogen. The inert gas may be heated by passing it through a tube ,heated by direct flame or by molten metal. Preliminary heating of the cold gases to a temperature not greater than 400‹ C. is obtained by heat exchange with gases from the reaction. The gases may also be heated by passing them through a purification catalyst, and the heating effect so produced may be increased by the addition of carbon monoxide or oxygen, e.g. by the addition of 3 to 5 per cent of oxygen. Catalysts are employed for the purification containing metals of the eighth group or compounds which are converted into those metals. The water formed in the purification process may be removed by drying or freezing in known manner.

Abstract: 787,224. Resiliently mounted seats. PINKEL, I. I. March 5, 1956 [April 25, 1955], No. 6802/56. Classes 52(1), 52(2) and 52(4) A crash resistant seat for aircraft or other conveyance has its pedestal constructed of two similar cup-shaped elements 11, 12 separated by a rubber sheet 15 and surrounded by a rubber sleeve 16 which forms a flexible coupling, the sleeve 16 being stretched when mounted to produce a force of at least 500 lbs. pulling on element 12. The sleeve 16 is turned up at the end and secured to form a loop 81 holding a steel cable 62 for attachment to a fitting 17 made up of a slotted head 60 and cylindrical stem 69 rotatable with respect thereto, the lower end of. the stem 69 carrying a pin 67 which passes through a slot 70 in a floor mounting plate 66 and the stem is then rotated through 90 degrees so that pin 67 becomes locked in recess 71, cable 62 being engaged in arcuate notch 82 in head 60. Clamps 61 fixed to element 11 allow the seat to be removed as an integral unit from the floor since they engage cable 62 when it is released from the tension of head 60. Arms 3 are fixed rigidly to seat pan 2 and the seat back 5 is joined to the pan in a manner allowing limited rotation of the back, the angle of the recline being controlled by a mechanism operated by a lever 6 on a shaft 45 carrying gears 43 which engage rack teeth 42 on slide locks 38 movable in channels 30 fixed on the side flanges 4 of the backs 5. Pins 34 attached to arms 3 engage slots in a tongue 35 slidable in channel 30 and carrying teeth 37 which can engage slots 33 in the channel when slide lock 38 is moved by the action of lever 6 so that protruberances 39 engage lands 48 on tongue 35 and the parts are thus rendered immobile to lock the seat back in the desired position. A torsion spring 49 keeps the arrangement in the locked position until the lever is raised. The seat back 5 is in the form of a rectangular air inflated mat 27 of material consisting of plies 73, 74 joined by a multiplicity of closely spaced substantially inextensible tie threads woven into the plies and padding 28 of foam rubber or the like. The seat is padded with layers of foam rubber 25, 26.
