Title: Method of producing nitrile perchlorate
IPC: C01B21/084
Filed: 1962-12-11
Abstract: Nitrile perchlorate, NO2ClO4, is prepared by reacting NO or NO2 (2 parts by volume), chlorine dioxide (2 parts' and ozone (at least 6 parts and preferably at least 12) as ozonized oxygen.  The ClO2 and NO or NO2 may be generated chemically or by electrical discharges, e.g. heavy current glow discharges, and are then immediately introduced, at 0.005-0.1 litres/hr., into the bottom of the reaction vessel. Oxygen containing 4-12% ozone is produced in an ozonizer operating at 6-10 kv., and introduced at 8-20 litres/hr.  The reaction is carried out at room temperature, and the product forms as a white film in the vessel.

Title: Brake pressure proportioning device
IPC: B60T8/26
Filed: 1962-12-11
Abstract: 1,002,610. Fluid-pressure brakes. KELSEYHAYES CO. Dec. 11, 1962 [Dec. 18, 1961], No. 46809/62. Heading F2F. A device for progressively modifying the ratio between front and rear braking pressures in an hydraulic braking system of a vehicle, to compensate for the weight transfer during deceleration of the vehicle, comprises a differential piston operating in a bore within a housing of the device, a passage through the piston for direct transmission of fluid during initial application of the brake, a piston-like element movable relative to the piston and comprising a valve seat arranged so that the flow of fluid through the passage is blocked upon closure of the valve seat, a deceleration-responsive element adapted to close the valve seat at a predetermined rate of vehicle deceleration, and spring means yieldingly resisting movement of the piston-like element relative to the piston. As shown, the device is inserted in the line 16 to the rear wheel brakes 22 of a vehicle from a master cylinder 20 which supplies the front wheel brakes 26 direct. The housing 10 of the device has a stepped bore containing a stepped differential piston 34 with a passage 52 through it, and which is normally held against the step in the housing bore by a spring 48. An annular piston-like element 70 having a combined seal and valve seat 72 is slidable in the smaller diameter bore portion 28 and is held spaced from the piston 34 by spring washers 78, 80 and an intermediate ring 82. A mass in the form of a ball 58 is contained in a cage 54 slidable in the bore portion 28 and formed with grooves 62 and passages 64, 69 for free movement of fluid past it. The ball is normally maintained against an annular shoulder 59 by a permanent magnet 56, while a light spring 66 maintains the cage in contact with the element 72. When the master cylinder is actuated fluid flows via inlet 12, passage 64, valve seat 72, passage 52 and outlet 14 to the rear wheel brake cylinders until a deceleration of the vehicle is attained sufficient to cause ball 58 to move away from shoulder 59 and close the valve seat 72, whereupon further build up of pressure in the master cylinder causes pressure in the outlet 14 to build up at a progressively lower rate owing to compression of spring washers 78, 80 by movement of element 70, until the ratio of inlet pressure to outlet pressure is such that further increase in inlet pressure moves the differential piston 42, so that the pressure ratio is thereafter determined by the ratio of the areas of piston 42.

The valve 54 is vertically reciprocable within a housing 34 and is controlled through the cable 60 such that when the hitch linkage lifts the planter from the ground the valve is closed, and vice versa when the planter is lowered. The metering mechanism 68 includes a rotatable disc 84 having two similar series of circumferentially spaced graduated orifices 86 and 88 such that when the disc is rotated into any one selected position out of ten an orifice is in registration with each inlet port 72 the orifices having equal flow areas. A wing nut 106 is provided to clamp the 'set' disc in the mechanism 68 and through the provision of a slot and pin arrangement 102, 98 associated with this nut it is possible to clamp the disc 84 in the upper position shown in Fig. 4 or in a lower position thus providing each pair of orifices, when in communication with the ports 72, with either one of two different liquid 'heads' deriving from the vertical distance between the horizontal line drawn through the ports and the plane at the bottom of the vent 32. Prior to passing through the metering mechanism 68 the liquid fertiliser drops from the tank into a readily releasable sediment trap 46 from whence it passes to the mechanism through an annular filter 52.

Title: Improvements in or relating to gas purification
IPC: C10K1/12
Filed: 1964-12-03
Abstract: In a process for removing CO2 from gas mixtures, e.g synthetic fuel gas, by the continuous circulation of an aqueous solution of K2CO3 at a temperature near its atmospheric boiling temperature between an absorber operated at super-atmospheric pressure, preferably over 100 lb. per square inch, and a steam stripper, operated at atmospheric pressure, e.g. as described in Specification 725,000, an ethanolamine is added to the solution, e.g. in amounts of from 0.3% to 10%, preferably 1% to 6%, by weight of the solution.  The operating conditions of the process (residence time of the gas in the absorber, degree of regeneration and circulation rate of the solution) should be such as to ensure a partial pressure of CO2 at the outlet of the absorber of less than 1.5 lb. per square inch, to achieve the maximum efficiency (see Fig. 2, not shown).  The process effects a saving in the amount of steam needed in the stripping zone. A minor amount of the solution may be more completely regenerated than the rest, or a minor amount of the regenerated solution may be cooled by 20 DEG  to 40 DEG  C., these minor amounts being returned the top of the absorber and the rest of the solution to an intermediate point in the absorber.  Comparative examples are described.ALSO:Carbon dioxide is removed from gas mixtures by a method similar to that described in Specification 725,000 in which a hot aqueous solution of K2CO3 is continuously circulated between an absorber operated at superatmospheric pressure and a steam stripper operated at atmospheric pressure.  The solution contains ethanolamine in amounts of from 0.3 to 10% by weight of the solution, and the operating conditions of the process (gas residence time in the absorber, degree of regeneration and circulation rate of the solution) should be such as to ensure a partial pressure of CO2 at the outlet of the absorber of less than 1.5 lbs. per square inch.
