The wire-cloth of a paper-making machine is supported over some of the de-watering devices by an open-mesh belt woven from one or more synthetic fibre materials. Prefered materials for the belts are nylons 6, 6-6, 6-10, 11, polyethylene terephthalate and polyethylene. These may be used as monofilaments or multi-filament yarns and may be coated with nylon. Staple fibre yarns of plied or cabled construction may also be used and the belts may be made of yarns of the same or different materials or of the same or different constructions in warp or weft. Fabrics for the belts are preferably woven endless and may then be cut tranversely and the ends joined after installation by sewing, lacing, or adhesives or by loops or metal clips arranged to receive pintles to form hinged joints. Before installation the fabrics may be stabilized by heat setting or by materials that react with or coat, or both, some or all of the fibres. Aldehyde resins are mentioned as suitable stabilizing materials. The Fourdrinier screens themselves may be woven from metal wire or combinations of metal, and synthetic fibre yarns, synthetic fabrics for both screens and belts being preferred. The belts have a coarser mesh than the screens. The transverse threads of the belt are arranged to bend about the longitudinal threads so that it is the former that receive the main abrasive wear while the latter take tensile strains. Suction box tops may be made of stainless steel and it is stated that the screens may be shorter than would be permissible without belts. The belt may extend under the screen above the suction boxes 40 and be guided by rolls 54, 56, 58, 60 and edge sensing paddles 61. In alternative forms, the belt may extend over suction boxes 40 and couch roll 14, over suction boxes, couch roll and some table rolls 36, or over all members traversed by the screen 10. In all the alternative forms, the belt is driven from the couch roll but in the first form is driven by the screen. Reference has been directed by the Comptroller to Specification 901, 772.

Title: Closed loop and yaw control for satellites
IPC: B64G1/28
Filed: 1973-03-22
Abstract: 1424824 Automatic control of satellite attitude RCA CORPORATION 22 March 1973 [27 March 1972] 13836/73 Heading G3R The attitude of a spinning satellite is automatically controlled by measuring an error related to the roll axis of the satellite and developing a corrective magnetic torque along an appropriate axis in response solely to the measured roll error. In the system shown, a pair of infrared sensors 22, 24 are mounted on a flywheel on the satellite so as to scan radiation from the earth's surface in cones located on opposite sides of the local verticle. Output signals from the sensors are passed through threshold devices 34, 36 and integrators or counters 42, 44 to produce pulses 46, 48 whose relative durations indicated deviations of the roll axis from an attitude defined with reference to the satellite angular momentum and the direction of the orbit normal. The pulses 46, 48 are compared in an error detector 50 which sets a time for which a circuit 54 counts clockpulses. If a certain count is exceeded, an overflow detector 58 produces a signal which energizes a magnetic dipole torquer 94 in a sense determined by a circuit 51, provided that a pre-set clock 90 or magnetometer 96 indicates that the satellite is in a suitable region of the earth's magnetic field for the magnetic torquing to produce the desired corrective change in attitude.

Filed: 1950-06-06
Abstract: 677,794. Presses for separating liquids from solids. HARTNER, H. A. June 6,1950, No. 14058/51. Class 46 In presses of the kind in which the threads of a pair of screws intermesh with considerable lateral clearance between their threads relative to the thickness of the latter and the core and thread diameters vary relatively so that the volumetric capacity of the space between adjacent turns of the thread of each screw decreases from the inlet to the outlet, the threads and cores are substantially in peripheral contact, throughout the operative length of the screws. In Fig. 1, the screw axes are parallel while the thread diameters 7, 8 decrease towards the outlet 6 and the core diameters 3, 4 increase. In Fig. 2 the cores are cylindrical while their axes are inclined at a small angle towards the outlet. The thread diameters decrease as before. In Fig. 3 both core and thread diameters decrease towards the outlet the screw axes again being inclined. In all cases the pitch preferably decreases towards the outlet, the last one or two threads having a greatly decreased pitch. Where the screw axes are parallel short cylindrical-thread screws, or screw portions with cylindrical cores, may be incorporated at the inlet or outlet end or both. A portion of each of the screws next to the outlet may be formed as a removable and suitably tubular end piece, preferably cylindrical. End pieces with different thread pitches may thus be inserted so that the pressure gradient near the outlet may be readily altered to accommodate different raw materials. Specification 458,970 is referred to.
