G.; 42-05, Latton Street, Elmhurst, Long Island, New York, and Thompson, H. H. ; 80, Pollard Road, Mountain Lakes, New Jersey, both in U.S.A.) Jan. 20, 1932, No. 1727. Convention date, Jan. 28, 1931. [Class 97 (iii).] In air-driven gyroscopic apparatus, one or more pairs of driving jets and the air impacted peripheral surface of the rotor are arranged so that upon inclination of the rotor an erecting or centralizing torque is provided. In the form shown, the rotor bearing frame 7 is mounted on horizontal trunnions 8, 9 in a vertical ring 6 pivoting on a vertical axis 4, 5 in a casing 1 having a front window 2 for observing the scale 30 and an aperture 3 closed by wire gauze through which air from the air drive may escape. Air under pressure is led through the hollow sleeves 14, 16, passageway 18 in the ring 6 and channels 19 to jets 20, 21 spaced at equal distances on either side of the central vertical plane of the rotor in a horizontal plane slightly above the trunnions 8, 9. Between the buckets 12 on the rotor and the jets 20, 21 is a baffle 22 secured to the frame 7 and provided with a slot 23 having its normally horizontal upper edge slightly below the upper part of the jets. When the frame 7 moves from its position perpendicular to the ring 6, one or other of the jets is intercepted and its reaction on the baffle causes a torque about the vertical axis tending to precess the gyro to its normal position. The jets 20, 21 may be inclined to one another to point to the centre of the bottom of the buckets. The device may be used for the automatic steering of aircraft, the ring 6 being provided with contact surfaces 31 co-operating with a trolley 33 mounted on a rotatable arm 34 which may be caused to follow up by the cord 35. The contacts 31, 33 control an air-driven servomotor which operates the rudder. For changing the course or correcting the position of the gyro, a switch may be caused to excite one or other of the solenoids 37, 38 mounted on the vertical ring 6, the arcuate cores 37<1>, 381 being secured to the frame 7. A manually operated conical cage is also provided to centralize and lock the gyro. In a modification the jets 20, 21 are mounted on the frame 7 and the baffle 22 is replaced by a slotted pendulous strip mounted in the ring 6 to pivot about an axis parallel to the trunnions 8, 9. Fig. 8 shows the application of the invention to a gyro vertical, the rotor being mounted about a normally vertical axis 50 in a casing 51 which pivots about two perpendicular horizontal axes. Two pairs of spaced driving jets 120, 121 and 120<1>, 121<1> are provided in the casing 51 which also carries pendulous blades 55<1>, 55 adapted to intercept the jets on the occurrence of tilting and to provide by the reaction of the jets thereon a restoring torque.

Title: A process of producing high-strength papermaking pulps,and paper products made from them
IPC: D21D1/30
Filed: 1963-10-11
Abstract: Strength properties of paper produced from a cellulose pulp are improved by a process of treating the pulp which comprises introducing it as a semi-solid moist mass containing separated fibres into a space formed by two opposed roughened surfaces spaced apart by a distance greater than the thickness of the fibres introduced, subjecting the pulp to a mechanical treatment in said space under compression exerted by said surfaces moving with sufficiently high relative tangential velocity and under sufficient power to cause inter-fibre friction, twisting and fibrillation of the fibres without substantially cutting the fibres while the pulp moves rapidly and continuously through said space, and discharging the treated pulp from said space.  The pulp consistency should be in the region of 10-60% preferably 20-35%. The refining apparatus used may be a single disc refiner, double disc refiner, or a conical type refiner. Suitable raw materials, which may be converted into pulp by any conventional means, are listed.  Substantially isotropic stretch may be imparted to the paper by creping the moist paper web as in Specification 903,508, that is by passing it between a hard roll and a soft elastic roll, with the hard roll driven at a speed greater than that of the elastic roll by at least 8%.  Substantially isotropic toughness characteristics may be imparted to the paper by drying the moist paper web in the end portion of the dryer section under reduced tension-for example by applying a negative draw between the dryer sections, by reducing the tension of the dryer felts, or by removing the final dryer felt altogether.

Abstract: 874,835. Fluid-pressure servomotor-control systems. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Dec 16, 1959 [Dec. 18, 1958], No. 40862/58. Class 135. [Also in Group XXVI] A turbine rotor has a circumferentially divided shroud which can be operated to mask the working surfaces of the rotor blades from fluid flow when the rotor is subjected to periods of rotation in a direction contrary to its direction when driven by the fluid flow. Turbine blades 4, Fig. 1, on a disc 5 rotate inside a turbine casing 1 having a recess 1A. A number of channelsection shroud segments 2 provided with operating rods 3 are fitted in the recess 1A and are moved radially inwards to shroud the blades 4 completely. Fig. 3 shows a marine turbine arrangement with an ahead turbine 9 and an astern turbine 13 mechanically connected. To prevent windage losses occurring whilst the ahead turbine is being driven the blades 4 of the astern turbine are provided with shrouds 2 as in Fig. 1. These shrouds are normally retracted by springs 15a but when the ahead turbine is operative the pressure in the inlet 10 thereof acts through pipes 11 on pistons 15 to move the shrouds over the blades 4. In a modification, Fig. 4, the ahead turbine inlet pressure instead of acting directly on the pistons 15 acts on a spring-loaded piston valve 16 to connect through a groove 17 an independent source of pressure 20 with the pistons 15. As soon as the turbine inlet pressure in the pipe 11 is high enough to overcome the spring 16a the valve piston is lifted off a seat 16b and a larger area is presented to the inlet pressure so that the valve moves suddenly to the right.
