Rafts.-Closed floating bodies s of variable volume, such as collapsable life-buoys or rafts, are provided with interior parts which, on expansion, effect the extension of the closed floating body. According to one form, the body 1, Fig. 3, is expanded by the inflation of a tube 5 arranged spirally around the body 1. As a variation, the closed ends 7, Fig. 4, telescope in the cylindrical body 6 and are expanded by rods 11 secured to portions which work in a cylinder 10 in communication with a source of compressed air. Specification 173,781, [Class 51 (i), Furraces and kilns, Combustion apparatus of], is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also forms in which the hollow body may be moved from a flat to an erect position to expand the body.

Title: Control systems

IPC: H02P9/00
Filed: 1963-04-30
Abstract: 1,048,383. Steam turbines. VSESOJUZNY TEPLOTEKHNICHESKY NAUCHNOISSLEDOVATELSKY INSTITUTE "DZERZHINSKY" (VTI). April 30, 1963, No. 16916/ 63. Heading F1T. [Also in Division G3] A turbogenerator is controlled under emergency conditions by varying the turbine power in dependence on changes in the generated power by means of a regulator, fed with real electrical power signals and stabilized by a non-linear flexible feedback, so that the regulator is inoperative during incidental disturbance in the generated and turbine power in a preestablished artificial dead-zone while in an emergency the regulator statically controls the turbine power in accordance with the generated power by transmitting a control signal to a unit controlling the energy to the turbine, which is proportional to the positive difference between the turbine and generated powers. As shown, the real electric power generated by a turbogenerator is measured by an electrodynamic wattmeter 1, the output signal from which is applied to an adder 3 together with a signal from an acceleration meter 7a, amplified in an amplifier 8a, which is representative of the positive difference in turbine and generated power, or alternatively, with a signal representative of turbine power derived from the position of a final control unit 4 of the turbine 9 or a meter 7c responsive to steam pressure and flow. A non-linear element 8b is used with meter 7b to compensate for turbine inertia and a non-linear differentiator 8c is used with meter 7c to compensate for low-power system instability. Integrating feedback is applied from the element 3 to the meter 1 having a time constant which is low under steady state conditions and high in an emergency so that the steady state control of the turbine power is in accordance with changes in the generated power. An element 6 and a non- linear element 10 are interposed between the adder 3 and the servomotor 4; the element 6 having a dead-zone or backlash to prevent a signal being passed which is below a set value. The adder 3 can be provided by a lever, a slide valve or an electrical moving coil arrangement and the feedback element 5 by a servomotor with a lever or hydraulic coupling or a magnetic amplifier. In a modified arrangement, Fig. 3, not shown, when the generator is connected from a network the steady state position of the final control unit is determined by a speed signal from a mechanical governor fed to the adder. In a further modification a turbine power limiter, Fig. 10, not shown, is employed which is responsive to the phase angle between the E.M.F. of the generator and the network voltage to cause, in an emergency, the unloaded generator to run in step to provide maximum synchronizing torque on reconnection. In a further modification, Fig. 12, not shown, the turbine power limiter off loads the generator when a transmission line is disconnected.

Title: Improvements in or relating to electrical switches of the kind utilising a conducting liquid

IPC: H01H29/00
Filed: 1952-07-09
Abstract: 765,177. Mercury and other conducting- liquid switches. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 14, 1953 [July 9, 1952], No. 17259/52. Class 38(5) [Also in Group XXXVI] Conductor parts 1, Fig. 1, are separated by a narrow gap 2 which is bridged by mercury or other conducting liquid 3 on which the current flowing through the conductor exerts a pinch effect. When the current is sufficiently large to cause the pinch effect to overcome the surface tension of the liquid, the latter is squeezed into a central cavity 4 and the circuit broken. Magnetic material may be used in the gap to augment the pinch effect. Fig. 3 shows an automatic. circuitbreaker in which the gap 2 is shaped to contain the liquid 3 by gravity. A fusible metal such as tin-lead alloy may be used in the gap, such metal liquifying before an overload occurs. In Fig. 4 a duct 8 communicating with the gap 2 is brought out through the side of the conductor and is connected to a valve V1 and a vertical tube 7 carrying a contact 9. When the current attains a predetermined overload value, the pinch effect in the gap 2 drives the liquid up the tube 7 until it completes a circuit through contact 9 to a motor M for operating valve V1. On opening of the latter, the liquid drains from the gap and the duct. It may be assisted by gas blown into a chamber 10 surrounding the gap. Alternatively the tube 7 may terminate in a reservoir into which the liquid is driven. In Fig. 5 one of the conductor parts is extended into the duct in the other part as a tongue 15 of resistance metal and means are provided for raising and lowering the level of liquid 3 to vary the amount of series resistance between the parts. Overload protection is provided by a tube 18 and contact 9 as in Fig. 4. The tongue 15 may be brought out through an insulating bush 19, Fig. 6, in the side of the conductor and connected to the duct through a switch 20 capable of operating at the reduced current when all the resistance is in circuit. This switch is opened after the liquid has broken contact with the tongue, to avoid sparking. Specification 765,178 is referred to.

Alternatively, outward movement of the segments 2 and inward movement of segments 1 may be limited by stop pins in the casing engaging recesses in the segments. In a further modification, two rings 14, 16 are arranged in a carrier with their joint surfaces staggered and are pressed axially by garter springs 3 engaging external inclined surfaces on the rings. Abutments 24 on the carrier limit outward movement of the small segments.

Abstract: 818,088. Defibrating wood chips &c. INTERNATIONAL BASIC ECONOMY CORPORATION. June 5, 1956 [Dec. 1, 1955], No. 17322/56. Class 96. Wood chips &c. are compressed to form a plug to withstand steam pressure as they are advanced from a feed opening 12, by a horizontal screw-conveyer 11 in a casing 9, the plug being later broken up to aid in defibrating the wood &c., as by a vertical screw-conveyer which is in the form of separate flights 14a, 14b, 14c, 14d, &c. on a shaft 13. The wood &c. may then be moved horizontally by a further screw-conveyer, also in separate flights and continually forced through an outlet opening of adjustable size. At the outlet, the release of pressure allows occluded steam to expand rapidly and disrupt the wood &c. The casings for the lower screwconveyers may be made of bars &c. presenting interior surfaces which tend to cut the wood or resist its rotation in the casing, thereby aiding the defibration. The bars &c. may also have small clearances between them to allow expressed water and fines to escape at desired regions. Alternatively the casing may be solid, and fluted longitudinally along its inner surface. In a modification, the casing includes cylindrical and converging portions, with different arrangements of bars, and different screw-to-casing clearances. Heating or cooling media may be circulated about the casings or within hollow screw press shafts. Compression of the woodchips &c. may alternatively be effected by a piston and cylinder.
