Abstract: HYDRAULIC POWER SOURCE               Abstract of the Disclosure A hydraulic power source for harnessing energy generated by the wave motion of a body of water.  A primary or main float has a plurality of secondary or satellite floats spaced outwardly therefrom.  The secondary floats are each attached to one end of a plurality of lever arms, the other ends thereof being attached to a plurality of rotatable shafts carried by the primary float so that up/down motion of the lever arms is translated into rotational motion of the shafts.  When placed upon a body of water, the wave motion causes the secondary floats to be displaced upwardly or downwardly relative to the primary float.  The motion of the secondary floats is translated by the generally vertical movement of the lever arms to the shafts to rotate the shafts.  The rotational motion of the shafts is translated into linear motion within the primary float by means of interacting cam surfaces which activate pistons of linear pumps.  The linear motion of the pistons within the pumps is used to pump a hydraulic fluid from a reservoir into pressure accumulators.  The pressure stored within the pressure accumulators may be selectively tapped as a source of power.

Abstract: ABSTRACT OF THE DISCLOSURE        Safety device for machine tools such as a stamping machine or a press with a reciprocating tool carriage.  The safety device includes a safety deflector surrounding the tool and having an opening at the operator's side covered by a transparent screen.  When the screen is open, it actuates a limit switch attached to the safety deflector to close the limit switch and to thus deactivate the drive of a clutch or the like of the tool.  A contactless switch is mounted in the deflector and in a workpiece support of the machine.  The contactless switches are operable only if their distance from the respective surfaces of the workpiece is below a predetermined minimum, otherwise they maintain the clutch inoperative.  Accordingly, the deflector must be close to the workpiece and the screen closed to render the tool of the machine operable.

Abstract: ABSTRACT           Retroreflective film, sheeting or the like having an array of light-reflecting right triangle prisms between a transparent surface layer and a backing layer.  The opposing triangular end faces of adjacent prisms are spaced apart to provide internal reflection therefrom.  The retro-reflective material provides efficient retroreflection at angles of incidence of about 30-85° and therefore is effective where light is directed in a path nearly parallel to a reflective surface, such as highway lane dividers or guardrail markers placed parallel to a highway.  Retrore-flective material on such markers becomes visible to an observer while yet remote from the markers.

Abstract: ABSTRACT OF THE DISCLOSURE            A diamond drill coring bit having an annular crown and inner and outer concentric side surfaces.  The crown is formed from a number of radially extending composite segments spaced apart circumferentially by a circumferential spacer material, all integrally bonded together.  Each composite segment consists of a number of diamond impregnated segments spaced radially from each other by a radial spacer material.          The diamond impregnated segments have greater abrasion resistance than that of the radial spacer material such that the radial spacer material will wear at a controlled rate greater than that of the diamond impregnated segments.  The radial spacer material has greater abrasion resistance than that of the circum-ferential spacer material such that the circumferential spacer material will wear at a controlled rate greater than that of the radial spacer material but not so great as to prematurely expose the composite segments.          The circumferential spacer material has good thermal conductivity to conduct heat from the composite segments, and substantial ductility to absorb drilling shocks.

Abstract: ABSTRACT OF THE DISCLOSURE         A die-cut, contoured, catamenial napkin of joined-together layers of sheet material assembled into a sandwich which combines a thin, soft, flexible peripheral portion for comfort with a thick central portion for increased fluid-holding capacity.  The uppermost layer is a thin batt of intermingled fibers provided with unbonded low density cushion areas sepa-rated by spaced bonded areas comprised of compressed fluid-distributing channels of higher density extending generally longitudinally of the batt and intersecting the ends and edges.  The central portion of the uppermost layer is upwardly deformed to provide a pad-receiving cavity in which a main fluid-holding element consisting of a relatively thick pad of absorbent material is posi-tioned in intimate physical contact with the uppermost layer while the horizontal face portions of the side and end walls of the central pad are free of contact with neighboring components.  The outer peripheral portion of the uppermost layer, and in the preferred embodiment, the lower surface of the fluid-holding element, is adhe-sively secured to a fluid-impervious bottom layer by a thin discontinuous film of adhesive.  Pressure-sensitive adhesive may be used on the bottom of the pad for releas-able attachment to a supporting undergarment.

Abstract: ABSTRACT OF THE DISCLOSURE            An onoard power supply and metering unit is con-nected, via an overboard cable e.g., 1000 meters long, to an underwater light-pulse projecting unit and a fluorescence-sensing receiver unit.  The operating power is transmitted to the under-water units by an onboard constant-current source, instead of a voltage source.  Likewise, the output signal of the receiver unit is transmitted through the cable in the form of a current, not a voltage.  The current of the receiver's photodiode is integrated, the peak value of the integral determined and held, this held value logarithmized, the logarithmized value sampled and held, and the held voltage converted to a current constituting the output signal.  The peak detector and log amplifier used are zeroed automatically, by a balancing signal applied during pulse measurements, but derived between pulse measurements.  The balanc-ing signal is derived by integrating a signal derived from the log amplifier's output signal, and is applied to the input of the peak detector, with the peak detector converted to simple voltage-follower operation during the deriving of the balancing signal.
