Abstract: A marine operations structure for use in arctic seas having steel/concrete composite ice walls positioned to permit multi-year ice ridges to be broken up with lower vertical forces imposed on the structure than heretofore possible. The structure provides for simultaneous contacting and fracturing of both surface ice floe and multi-year ice ridges by proportioning of the ratio of the annular dimension of a first sloped surface to the radius of the structure within the range of about from 0.15 to 0.30. The structure is fabricated by modular construction techniques which lowers total construction costs. The structure is in the form of a sixteen-sided polygonal sloped walled marine structure with internal ballast tanks for providing gravity founding of the structure on the sea floor. Modular drilling equipment is provided for and supported by the structure for use through two rectangular shaped moon pools extending vertical throughout the central core of the structure.

Abstract: Apparatus for an earth station antenna is disclosed herein including a parabolic dish antenna pivotally carried on an upper support post mounted for rotation about a vertical axis. Pivotal linkage interconnects the antenna with the upper support post for rotation about a horizontal axis. Power drive is carried in the upper support post for pivoting the antenna about its horizontal axis via the linkage while separate power drive operably couples between the upper support post and a stationary lower post for rotating the upper support post and the antenna about the vertical axis. The lower end of the lower support post is provided with a mounting recess for insertably receiving the terminating end of an upright mounting stanchion.

Abstract: A tool for tightening a band to a predetermined tension about an article by pulling the band through a buckle thereon includes a reciprocable feeder within a housing for gripping the band, incrementally pulling it into the housing, releasing it and then regripping it at another position while it is held by a supplemental grip within the housing. A handle pivotally mounted in the housing operates the reciprocable feeder through an operative connection responsive to the tension of the band in such manner that when a predetermined tension has been reached, the operative connection is disengaged while the band remains gripped by the feeder. The handle which operates the feeder may then be swung in the opposite direction to actuate a member which pushes the wrapped article around the nose of the tool in such manner as to bend the band about its buckle and thus to retain the desired tension therein, after which the band may be cut off at a position within the nose of the housing.

Abstract: A reel pipelaying vessel having multiple reels for laying operational lines in a wide range of water depths. An operational lines laying device is mounted on the vessel in order to provide supporting means for the simultaneous layout of a plurality of operational lines at a common velocity and in a predetermined relationship to one another. Motive means are interconnected to the multiple reels in order to control the rate of layout. Separate or combined straightening and tensioning devices can be employed for handling the rigid walled pipeline contained within the operational lines. The straightening and tensioning devices can be mounted for pivotal movement with respect to the vessel deck or can be operated in fixed planes with respect to the deck. Six or more operational lines can be simultaneously laid out with the vessel described.

Abstract: An improved champagne bottle opener comprising a flanged yoke-shaped cork extractor pivotally connected to a levered actuator and further pivotally connected to a flanged yoke-shaped platform which engages the flanged neck of a champagne bottle.

Abstract: A mobile sea barge having a unitary lower hull which has sufficient buoyancy to float the entire barge, an upper hull spaced from the lower hull by a single, centrally-positioned, vertical member, and a movable stabilizing hull arranged about the central support member for controlled movement between the upper and lower hulls is provided. Controlled movement of the stabilizing hull permits the operational modes of submerging and emerging of the lower hull into or from a bottom-founded gravity-forced mode from which drilling operations can be carried out. In the bottom-founded mode on the sea floor the barge functions as a gravity platform. Movement of the stabilizing hull is provided by a plurality of jacking legs and jacking units which constitute the control devices. The barge can be quickly switched between the surface-floating and the gravity-forced, bottom-founded modes. Controlled vertical descent to the sea floor is provided by the static stability of the stabilizing hull.

Abstract: A collapsible stand for a water dispenser or the like, which stand is formed of four side panels joined by corner members, with the corner members having hinged sections permitting the assembled stand to be positioned in an open configuration for use and in a flat or collapsed configuration for storage and transport.

Abstract: A security system for a vehicle such as an automobile, which provides an audible alarm and radio transmission to a pager when an attempt is made to enter the vehicle. A passive system which automatically sets itself when the ignition is turned off, with an exit time delay permitting the operator to leave the vehicle after turning the ignition off and with an entrance time delay permitting the operator to enter the vehicle and turn the alarm off. A sound detection system which provides an alarm when vehicle intrusion is attempted as by breaking glass or use of a pry bar, while discriminating against ordinary street noises such as operation of other vehicles, sirens and the like. An alarm operated by battery voltage changes such as are produced by opening of a door and energizing a courtesy light, while inhibiting alarm when there are other battery voltage changes such as those produced by operation of a cooling fan.

The band comprises a single strip of metal with a strap section and a buckle section, with the buckle section having an opening for receiving the strap section to form a circle for positioning about the shield and connector. The band is tightened by pulling to the desired size, after which it is folded over to lock the band in place and cut to an appropriate length.

Abstract: A circuit for providing input power to the horizontal deflection coil or yoke for a raster scan type of cathode ray tube. The circuit includes a closed loop current sensor which uses an operational amplifier to compare the sensed current with an adjustable reference voltage to provide a control for the current, thereby providing a constant current power source for a resonant deflection yoke flyback circuit. The current drive and S shaping capacitor are directly coupled to the deflection coil, omitting a coupling transformer and a linearity coil.

Abstract: Apparatus and method for measuring the density of sperm in a sample and for calculating the magnitude of dose required for artificial insemination. An optical assembly with light source, specimen holder and photodetector providing a signal to an amplifier the output of which is proportional to absorbance of the sample. A signal selection system utilizes three parallel signal channels with each having a different correction factor for matching the absorbance signal to actual density count, and including means for selecting the appropriate signal channel as a function of signal amplitude, with the output when calibrated providing the direct reading of the sperm density. Knowing the number of sperm cells desired per insemination and the percent motility of the sample sperm, the required dose is calculated as a function of the density count.
