Title: Improvements in gyroscopic apparatus
IPC: G01C21/18
Filed: 1923-05-25
Abstract: 220,726. Jackson, P. R., (Sperry Gyroscope Co.). May 25, 1923. Gyroscopic apparatus. - For damping the oscillations of a gyroscopic pendulum, an auxiliary free pendulum universally supported thereon is adapted to control the operation of restraining forces when relative inclination of the two pendulums occurs. In the form shown in Fig. 5 the rotor 51 is mounted in a casing 50 which is pendulously supported in a gimbal ring 60 pivoted in standards 63. The casing is divided by a partition 55 and has a hemispherical lower part provided with a number of rows of nozzles 72, the orifices of which are disposed tangentially of the casing, Fig. 10. A free pendulum 75 is universally supported by the partition 55 and has a bob 76 which closely fits the casing. The rotor 51 is provided with buckets 65 and is driven by air supplied through a tube 47 and passing through the hollow supporting trunnions and the hollow gimbal ring 60. The air after driving the rotor passes through slits 71 and through apertures 56 in the partition 55 and leaves the casing by such of the nozzles 72 as are not covered by the bob 76. Under normal conditions the several rows of nozzles are equally uncovered, but when relative inclination of the two pendulums occurs, the balance is upset and the air expelled from the nozzles exerts a restraining force on the gyroscopic pendulum. In the case of a gyroscopic pendulum mounted on an aircraft the air supply may be obtained by a rotary pump including a propeller operated by the movement of the craft through the air. In a modified construction, the partition 55 is not formed with apertures but the, air supply is divided, part passing into the upper part and the remainder into the lower part of the casing. In a further modification the supply of air to the lower part of the casing is obtained by separate means comprising a centrifugal device mounted on the rotor shaft 52 and including an annular Venturi tube.

Title: Improvements in or relating to the preparation of fluorocarbon compounds
IPC: B01J19/00
Filed: 1956-05-07
Abstract: Phosphorus trifluoride is obtained as a byproduct in the preparation of fluorocarbon compounds by contacting phosphorus pentafluoride with carbon at a temperature of at least 1000 DEG  C. It may be reconverted to PF5 by treating it with chlorine to form PF3Cl2, heating this to cause disproportionation in accordance with the equation: 5PF3Cl2-->3PF5+2PCl5, and reacting the PCl5 with calcium fluoride at 300-600 DEG  C. to form more PF5.ALSO:Fluorocarbon compounds, especially carbon tetrafluoride and tetrafluoroethylene, are produced by the contacting phosphorus penta fluoride with carbon at a temperature of at least 1000 DEG  C. (e.g. up to 2600 DEG  C.) for a time sufficient to ensure a substantially complete conversion of the PF5 to PF3 and thereafter cooling the product to below 500 DEG C. (preferably in under 10 milliseconds to obtain the maximum yield of tetrafluoroethylene).  In examples, PF5 is passed through a graphite tube containing granular graphite heated by induction to about 2000 DEG  C., and the products quenched to 500 DEG  C. in very small time to give mainly CCl4, and tetrafluoroethylene with small quantities of other products; and a table gives the products, mainly the above, under various similar conditions in a tube heated by a resistance coil; at lower reaction temperatures and with longer quenching times, mainly carbon tetrafluoride is formed.  The PF3 formed may be reconverted to PF5 (see Group III) and the latter recycled, as also may be fluorocarbon products other than tetrafluoroethylene.  Specification 758,477 is referred to.

Abstract: 566,718. Silvering ; extracting silver. JOHNSON, MATTHEY, & CO., Ltd., BOX, E. R., and WYETH, E. J. Sept. 7, 1943, No. 14624. [Classes 82 (i) and 82 (ii)] The surfaces of non-metallic articles such as glass, mica, porcelain, earthenware or electrical insulating materials, are silvered by applying by painting, spraying or printing a paste consisting of finely-divided silver, a fusible flux in a combustible organic medium, the coated article then being fired to burn away the organic matter and leave a firmly adherent silver layer. The paste may be prepared by grinding precipitated metallic silver with a flux in an organic painting, spraying or printing medium, the spraying medium being a solution of cellulose nitrate in amyl acetate, the painting medium a solution of colophony in pure turpentine and silk screen printing medium a solution of cellulose nitrate in amyl lactate. When the paste is required for printing the medium may be any of the usual oils used in making printers' or lithographic inks. To retard the rate of drying pure oil may 'be added. The finelydivided silver may be prepared by treating solutions of silver salts, e.g. oxides, carborates or oxalates, with a metallic reducing agent such as zinc powder, inorganic agents such as soluble hypopliosphates or hydrosulphites, titanous salts and alkaline hydrogen peroxide solutions or organic agents such as formaldehyde, formic acid and alkaline tartrate or citrate solutions.
