Abstract: ABSTRACT OF THE DISCLOSURE               Disclosed herein is a marine propulsion device including a lower unit having a gear case normally submerged in water and a propeller rotatably mounted in and extending rearwardly of the gear case.  One or more grooves in the outer surface of the forward portion of the propeller outer hub in front of the propeller blade serves to trap and store fish line or the like which becomes entangled in the propeller and thereby prevent such materials from entering the gear case.  The groove extends around at least a portion of the outer periphery of the forward portion of the propeller outer hub, includes one or more portions which are open to a hollow interior area in the propeller, and has sufficient dimensions to serve as a barrier against propagation of fish line or the like along the outer surface of the propeller outer hub toward the gear case.

Abstract: S. Olsson - 1X       METHOD TO CONTROL STOPS OF AN INTERMITTENTLY           OPERATING ELECTRIC MOTOR          ABSTRACT   The invention concerns a method to control the stops of an intermittently operating electric motor.  The motor current is measured at even intervals and a mean value is created from the measured values.  An actual value is compared with said mean value and a signal is given to stop the motor if the actual value deviates from the mean value a predetermined amount.  Each new measured value replaces the first measured value in the series.

Abstract: A child resistant box (20) which is composed of a base (23), a lid (22) and a hinge (30) connecting the base (23) and lid (22) together. A latching mechanism is located on each of the two sides of the box for releasably retaining the lid (22) to the base (23). The box (20) can be moved between open, intermediate, and closed positions. The box (20) also includes a means for biasing the lid from the intermediate position toward the closed position. To open the box (20) the lid (22) is compressed to the intermediate position. In this intermediate position, the latching mechanism may be disengaged by exerting manual pressure thereon toward the center of the box (20). Once pressure is exerted simultaneously on both latching mechanisms the lid (22) is released and the biasing means moves the lid (22) at least partially toward the open position. The operation of this box (20) is particularly well-suited for the elderly. Although this child resistant box can house virtually anything, it is particularly well suited for housing a set of blister cards which include a plurality of medicaments to be taken at different times during a therapeutic regimen.

Abstract: A system and method for determining the position of towed marine object relative to a towing vessel. The system comprises a towing vessel, a slave vessel, and the towed object. An acoustic transceiver is located on either the towing vessel or the slave vessel with an acoustic receiver located on the other vessel. One or more acoustic transponders are associated with the towed object. The distance between the towing vessel and the slave vessel is determined, for example, by radio navigation which is calibrated by a high precision range-range system. The acoustic transmitter emits an interrogation signal which causes the transducer(s) to emit a response acoustic signal which is recorded at the two receivers. Using the time for the response signal to reach each of the receivers and the velocity of sound in water, the distance of the transducer from each vessel is calculated. With the three distances the location of the transducer relative to the towing vessel is determined by trilateration. The system is especially useful for determining the horizontal profile of a towed seismic cable, where a series of transducers are located along the cable. The interrogation signal will interrogate each transducer sequentially and by trilateration of each transducer a very accurate representation of the horizontal profile is obtained.

Granted: 2000-01-18
Abstract: A process for preparing an extruded thermoplastic resin elongate foam body comprising an alkenyl-substituted aromatic resin characterized as having a density of between about 0.9 to about 3.5 pounds per cubic foot is described. The process comprises the steps of (A) heat plastifying the thermoplastic resin; (B) adding at least one fluid blowing agent comprising at least one of 1-chloro-1,1-difluoroethane, 1,1,1,2-tetrafluoroethane and 2-chloro-1,1,1,2-tetra-fluoroethane; (C) uniformly mixing the blowing agent in the resin under a pressure sufficient to prevent blowing of the resin thereby forming a blowable resin mixture; (D) extruding the mixture into a region of reduced pressure which is less than atmospheric pressure wherein the blowable resin mixture expands into a foam body; and (E) cooling the foam body.      In one embodiment, the region of less than atmospheric pressure is formed by an elongated chamber (15) with the blowable resin mixture passing through a die (20) at one end of such chamber and such foam body passing through a pool of water (17) at the opposite end of the chamber. The process results in the formation of extruded expanded thermoplastic resins such as polystyrene resins characterized as having relatively small average cell sizes such as from about 0.2 to about 0.5 mm., improved and higher compressive strengths, and higher cell volumes.
