Abstract: Abstract of the Disclosure A semi-submersible floating platform having a deck supported above water by four partially-submerged main columns attached to the deck and by two totally-submerged pontoons each attached to a different pair of the main columns is provided with a damping control system for suppressing undesirable motion of the platform caused by wave motion. This damping control system includes a velocity sensor for sensing the velocity of at least one of heave, roll, and pitch components of the undesirable motion of the structure and further includes control apparatus for exert-ing on the platform a damping control force that is a function of and in phase opposition to the sensed velocity. The control apparatus includes one or more ballast tanks in communication with the water and apparatus for driving water from or drawing water into each ballast tank as a function of the sensed velocity. Each ballast tank may be included within an associated column or pontoon of the platform and may be provided with a ballast sensor for sensing the actual volume of water within the ballast tank relative to a mean volume of water therein. In this case, the control apparatus may include apparatus responsive to the velocity sensor and each ballast sensor for driving pump apparatus to vary the actual volume of water within each ballast tank relative to the mean volume of water therein as a function of the sensed velocity. Alternatively, each ballast tank may be mounted on the outboard surface of an associated column of the platform at approxi-mately the location where the ambient water level intersects the column. In this case, the control apparatus may include pump apparatus for varying the air pressure in each ballast tank as a function of the sensed velocity to drive water from or draw water into each ballast tank. Although the damping control apparatus is especially effective for suppressing undesirable motion of the platform at wave periods substantially equal to the resonant period of the platform, it is also effective at other wave periods. Suppression of undesirable motion at such other wave periods may also be achieved by modifying the geometry of the columns and/or pontoons which are apportionable in sectors about a reference point of the platform. This may be accomplished, for example, by altering the cross-sectional area of the pontoons along the length thereof or by otherwise modifying the pontoons so that the portion thereof in each sector has an effective center of dynamic pontoon force that is disposed outboard of the ef-fective center of displacement volume of the associated portion of the columns in the same sector.

Abstract: A B S T R A C T     A construction of an active filter having the same characteristics as a predetermined passive filter is described in which the capacitors of the passive filters are replaced by a topologically equivalent first network of resistors and the inductors of the passive network are replaced by a topologically equivalent second network of resistors, the two net-works of the resistors being interconnected in a manner corresponding to the connections in the passive filter by means of negative impedance converters having conversion ratios effective to convert resistance into negative capacitances and resistance into negative inductances.  The input and output to the active filter may be through similar negative impedance converters or may be directly to  points in one or other resistive networks. An additional resistor connected between points of the active filter which correspond to terminals of a resonance circuit in the passive filter can provide Q-factor enhancement.  A suitable design of negative impedance converter uses an operational amplifier the two inputs of which respectively form the input and output terminals of the converter with impedances connected from the output of the amplifier to its inputs.

Granted: 1982-05-04
Abstract: 274.40 TH/AB     ABSTRACT OF DISCLOSURE    The present invention relates to a device for temporary or per-manent occlusion of channels or hollow spaces in human or animal bo-dies, particularly oviducts and spermatic ducts.  According to the invention the device consists of a body made of a material, which, when brought into contact with a body fluid, swells at least 20%. In other respects, the material should be essentially inert and harmless to the body fluid and surrounding tissues and should not be absorbed by the human body.  Suitable materials for this purpose are hydrogels.        In use the body is introduced into a channel in the unswollen state and will thereafter swell, when in contact with the body fluid, so that the body, which can pass through the channel when inserted, will swell and effectively contact the walls of the channel occluding the same, simultaneously with the body being anchored in position.

Abstract: ABSTRACT OF THE DISCLOSURE           The rotational direction of a capstan motor can not follow immediately with the command signal from a system control because of the mechanical inertia of a tape trans-porting system.  In the new system of the invention, the command signal is employed together with a rotational signal from a frequency generator for supplying a actual rotational direction indicating pulse.  Thus obtained direction indicat-ing pulse is necessary for the tape transporting system, and is used in supplying a braking current to the motor, actuating a pinch roller, and so on.

Abstract: ELECTROSTATIC AND ELECTROLYTIC CLARIFIER            ABSTRACT OF THE DISCLOSURE           A fluid, such as air or water, carrying suspended solids is directed between a pair of oppositely charged, corrugated surfaces in order to subject the flow to an undulating action that increases the frequency with which the solid particles impinge against one another, thereby increasing the rate of flocculation of the solids. In the case of airborne particles, the corrugated surfaces are arranged in an upright condition so that the flocculated particles attracted to one or the other of such surfaces gravitate therefrom into a conveying mechanism that delivers such particles to a collecting receptacle.  In the case of liquid-borne particles, the flow is forced to travel upwardly against the force of gravity after passing between the surfaces, thereby encouraging the flocculated particles to settle out into a sump that is associated with the uphill flow passage.  In each case, two sets of charged surfaces may be utilized, the first having at least one of its surfaces insulated from the flow for electrostatic action only, while the second has neither surfaces so insu-lated for electrolytic action.
