Abstract: ABSTRACT OF THE DISCLOSURE         An articulated fluid loading arm especially suited for transferring petroleum from a floating storage and loading terminal to a marine tanker.  The arm com-prises a support boom pivotally mounted on the deck of the terminal, a pair of fluid conduits extending along the boom from risers at the deck, and a dual-flow passage drop-pipe assembly suspended from a carriage that rides in a track on the boom. The drop-pipe assembly comprises four rigid pipe sections interconnected by swivel joints into a parallelogram-like structure, one corner thereof pivotally connected to the carriage and the opposite cor-ner connected to a pull-in type pipe connector for releasably securing the arm to a tanker manifold.  A ten-sioning cable extends from the pipe connector up to the carriage and then along the boom and around a motion-compensating tensioner to a dead-man winch for lowering, raising, and supporting the drop-pipe assembly, and means are provided to disconnect the drop pipe assembly from the fluid conduits at the outer end of the boom so that the assembly can be brought in on the carriage to the station deck for servicing.  A tag line connected between the pipe connector and a tanker winch allows the pipe connector to be gently pulled down to connect with the tanker manifold even when the tanker is moving up and down.     -1a-

Granted: 1982-03-30
Abstract: ELECTRONIC CALORIE COUNTER            ABSTRACT OF THE DISCLOSURE An electronic calorie counter is disclosed which provides a digital readout of the rate of calorie consumption with exercise by the user by sensing the vertical component of the motion of the user, and translating that motion into electronic impulses. The vertical component of the user's motion is constantly detected using a magneto-electric transducer in combination with means for defining an opto-electric axis in the transducer. The output of the opto-electric means is combined with a clock-controlled gate to provide a burst of impulses over a unit of time which is proportional to the vertical acceleration sensed. The gate output is supplied to a program-controlled processor utilizing a mathematical equation derived to analyze calorie consumption in humans with exercise. The processor is also res-ponsive to several input switches indicating the physical parameters of the individual user in calculating calorie consumption. The microprocessor output, as displayed, comprises the calories consumed by the user over a fixed period of time.

Abstract: ABSTRACT OF THE DISCLOSURE      A flexible optical signal transmitting cable is provided which comprises a plurality of elongated wave shaped optical fibers which extend in an axial direction and transversely corrugated, longitudinally seam welded, metallic tubular member formed about spacially separated from the plurality of optical fibers and which only partially fill the inner cross-section of the metallic tubular member.  Water resistant support means is provided which fills the unoccupied remaining portions of the complete interior cross-section of the metallic tubular member along at least longitudinal intervals of the metallic tubular member.  The water resistant support means prevents axial propogation of any water penetrating the interior of the metallic tubular member and provides direct, non-rigid, radial support for each of the optical fibers within each of the longitudinal intervals of the tubular member for permitting unilinear axial unfolding thereof upon tensional forces being applied thereto.  The optical fibers have been continuously formed by feeding such in a longitudinal path while simultaneously shaping a metallic strip about the optical fibers into a tubular member, injecting a water resistant filler material at a first point along the longitudinal path prior to the closing of the opposite longitudinal edges of the metallic strip and welding the longitudinal edges and corrugating the welded tubular member downstream of the first point.

Abstract: ABSTRACT OF THE DISCLOSURE           A novel Direction Finding system is described, using a small aperture circular array of vertical dipoles, the outputs of which are rotated in phase by angles corresponding to their angular location on the array circle.  A phased ring combiner is used to add the dipole pair outputs, giving two resultant waveforms, one advanced in phase and the other retarded by the same angle .THETA. where .THETA. is the relative bearing angle of the incoming signal.  The phasing elements are made independent of the signal frequency either by the use of all-pass networks or by prior conversion to a fixed intermediate frequency.  DF processing can be performed by a digital phase meter which computes the phase difference between the two resultant waveforms.  In addition, an orthogonal DF display is available through a .SIGMA./.DELTA. conversion.

Abstract: Abstract A monolithic crystal filter formed by a multi-section piezoelectric resonator having anodizable electrodes is subjected to plasma from a low energy oxygen glow device to adjust the frequency response.  The electrodes are selectively connected to potentials whereby the electrodes are individually anodized to increase the density thereof and change the frequency response of the resonator.  The glow device includes anode and cathode rings separated by an insulator ring which holds a cathode screen across the cathode.  The anode ring has a concave face and the inside diameter is generally the same as the diameter of the resonator so that the resonator can be placed close to the anode and plasma is localized on the resonator elec-trodes.  The electrodes are connected in a frequency measuring circuit so that the response is monitored and the extent of anodization of the individual electrodes is controlled.
