Title: Gyroscopic instrument having a fluid rotor
IPC: G01C19/14
Filed: 1961-01-13
Abstract: 928,487. Impedance measurement. SPERRY RAND CORPORATION. Jan. 13, 1961 [Jan. 21, 1960], No. 1501/61. Class 37. [Also in Groups XX and XXXVIII] The housing 13 which is rotated about an axis 14 by means of electric motors 71, 72, has a spherical cavity 12 which is filled with a liquid forming the rotor of the gyroscope so that when an angular rate is imposed on the apparatus about an axis perpendicular to axis 14 the spin axis of the liquid deviates from axis 14, the deviation being measured by pressure-responsive pick-offs such as 24, 25. The housing 13 is floated with the same liquid as that which forms the rotor, within an inner housing 57 which is mounted within an intermediate housing 63 carrying the bearing shafts 67, 68, the housings 13, 57, 63 being connected together by fixed balls 60, 64 spaced 120 degrees apart to provide a thermal path eliminating thermal gradients but preventing the transmission of strains to housing 13. Each capacitive pick-off comprises a resilient diaphragm mounted between fixed permeable members, one side being in communication with a conduit 32, or 46 and the other side being connected through a conduit such as 22 or 23 to a port such as 20, 21 or 40. The ports 20, 21 are placed at equal angles e.g. 45 degrees to the axis 14 and in a plane containing axis 14 and the normally vertical axis 15. Another pair of pick-offs, conduits and ports, such as 40, are positioned at the opposite end of housing 13 to pick-offs 24, 25, in space quadrature i.e. the ports are at an angle of 45 degrees to axis 14 and are in a plane containing axis 14 and the perpendicular to axis 15. Each capacitive pickoff 24, 25, 42, 43, Fig. 7, is connected in a tuned bridge tee circuit with a pair of inductors which are mounted at the same end of housing 13 as the associated pick-off and in space quadrature therewith, i.e. coils 50-53 are associated with the capacitive pick-offs 42, 43 which communicate with conduit 46. Each tuned bridge tee circuit, e.g. circuit 81, is excited by a reference source and the values of its elements 24, 82, 85, 86 are so chosen that when the spin axis of the liquid is aligned with axis 14 there is no output. By differentially connecting the tuned bridge tee circuits containing associated pickoffs 24, 25 and 42, 43, respectively, energizing them through magnetic slip ring 73 and feeding their outputs to the quadrature rotor windings of a resolver 74 on shaft 67, the resulting currents from the stator windings of resolver 74 correspond to the deviation of the spin axis of the liquid rotor from axis 14 about the two sensitive axes of the apparatus perpendicular to axis 14. Specification 600,605 is referred to.

Title: Apparatus for catching and treating blood from slaughtered animals
IPC: A22B5/04
Filed: 1962-01-16
Abstract: 932,411. Catching blood from a slaughtered animal. G. MAUCHER. Jan. 16, 1962 [Jan. 24. 1961], No. 1507/62. Class 28 (2). [Also in Group XXIX] Apparatus for catching blood from a slaughtered animal and mixing the blood with a solution of anticoagulant comprises a blood catching and mixing unit 7, Fig. 1, for attaching to the animal, a blood collecting-tank 10 to which the unit is connected by a flexible outlet pipe 2 for the blood and a flexible pipe 1 for the supply to the unit of anticoagulant, such as a solution of the sodium salt of a polymeric phosphoric acid; in the arrangement shown, the pipe 1 for the anticoagulant is the inner of two concentric pipes. The catching and mixing of the blood are performed under suction produced by a pump 14, moisture being collected in an air tank 11 with which an air filter (not shown) may be associated. The unit 7 shown in Figs. 2 and 3 has a transparent casing 7a, rubber cushioning 8 and hooks 9. A wire loop 4 is first inserted into the animal's wound and is then turned through about 90 degrees by a handle 6 to increase the flow of blood. The turning causes gripping hooks 5 to open into the animal, as shown in Fig. 3, and also the release of the closure 3 for the pipes 1 and 2. The quantity of anticoagulant solution provided is regulated by screw adjustment of a conical pin 3b. The cross-sections of the pipes 1 and 2 should correspond approximately to the proportions of the anticoagulant solution, and blood and anticoagulant solution respectively.

The epoxides are selected from epoxides having 1, 2, 3, 4 or more oxygen-carbon rings in which an oxygen atom is joined to 2 carbon atoms in the ring and may contain 1, or 2, or more, aliphatic carbon to carbon double bonds.  The epoxides may contain alkenyl, nitro, ether, and ester substituents. The Specification includes a long list of suitable epoxides.  Those exemplified are propylene oxide, allyl glycidyl ether, styrene oxide, phenyl glycidyl ether, and a mixture of allyl glycidyl ether and propylene oxide.  The Specification contains an extensive list of organometallic compounds of which zinc diethyl and aluminium triethyl are exemplified. The polymerization may be effected in bulk or in a solvent, preferably a hydrocarbon but carbon tetrachloride, chloroform, diethyl ether, or trichloroethylene may also be used. The polymers may be recovered, and catalyst residues removed by conventional techniques, e.g. water, alcohol, and/or acid and alkaline treatments.  Antioxidants such as phenyl beta-naphthylamine may be added prior to, or during polymerization. Cross-linking inhibitors such as nitrobenzene, dinitrotoluene, dinitrodiphenyl, nitrodiphenylamine, or chlorodinitrobenzene may be added to the polymerizate. The polymers may be compounded with rubbers, and resins, curing agents, fillers, extenders, reinforcing agents, ultraviolet light absorbers, dyes, pigments, plasticizers, or lubricants.  In Example XII, a copolymer of propylene oxide and allyl glycidyl ether is sulphur-cured both in the presence and absence of carbon black.ALSO:A catalytic composition for the polymerization of organic epoxides comprises at least one compound selected from antimony trioxide, antimony tetraoxide, antimony pentaoxide, boron oxide, chromium trioxide, stannous oxide, or stannic oxide, and at least one organometallic compound selected from AlR3, CdR2, or ZnR2 where R is a hydrocarbon radical of 1-20 carbon atoms.  The organometallic compound is preferably applied to the oxide as a solution in an organic solvent, but it may be applied to the oxide as a vapour.  The mixing may be effected at elevated temperature, or below room temperature.  The Specification contains an extensive list of organometallic compounds of which zinc diethyl and aluminium triethyl are exemplified.

The severing device is as described in U.S.A. Specification 2,778,424 and includes restraining rollers 55, 56 and snatch rollers 98, 100 rotating at a higher speed than the restraining rollers. The snatch rollers are supported by a frame 83 adjustable along a rack 93 whereby the spacing between the restraining and snatch rollers may be adjusted according to the length of the cards being bundled. The interleaving and stacking device comprises two sets of rollers 35, 150 and 36, 151 mounted on a base plate 26 secured to the frame 83. As shown in Fig. 2, the rollers are set at an angle to the longitudinal centre line of the web and diverge in the forward direction of the web travel.
