Abstract: A radio system and method for monitoring and locating objects, including individuals, animals and articles, both locally and on a nationwide scale use monitoring base stations communicating by ID code with portable transponders which are secured to the objects to be monitored. The transponder responds to signals transmitted by the base, the latter indicating by an alarm the absence of a timely appropriate response from the transponder. The base is capable of performing and participating in homing techniques to locate a lost transponder. A list of the IDs of all transponders reported missing is distributed from a central source by nationwide communication to a network of radio stations, each station broadcasting the list in an encoded signal in repetitive sequence along with regular programming. Cruising vehicles of public safety departments operating locally nationwide are equipped with automatic monitors for receiving specially coded messages including IDs from transponders within their areas.
Abstract: A Bourdon tube pressure gauge has a movement amplifying mechanism comprising a pinion of segment shaped permanent bar magnets extending radially and terminating at a circular edge magnetically driven by a pivotally mounted rack segment having an arcuate band of permanent bar magnets arranged in parallel alignment with polar axes extending radially of the rack and transversely of the band. One of the poles of each of the magnets of the band is located along a driving arcuate edge thereof which faces and magnetically drives the circular edge of the pinion by magnetic attraction of opposite poles. The polarity of adjacent magnets on both the pinion and rack segment is reversed providing alternate N and S poles around the pinion circular edge and along the driving edge of the band, respectively. In one form of movement, the rack segment is formed with an opening and the driving arcuate edge faces the opening in which the pinion is positioned for operative magnetic engagement between the band and pinion.

Abstract: A system for decontaminating the aquifer of hydrocarbon spills utilizes one or more wells each fitted with a perforated screen into which a skimmer formed as a receptacle is suspended by a cable for vertical movement to desired levels, the receptacle having an open top and a diameter sized to fit into the screens with only slight clearance. Water is pumped from the receptacle into a separation tank and because of the slight clearance between the screen and receptacle refilling occurs from ground water at or above the level at which the open top edge of the receptacle is located with respect to the surface of the aquifer. Floating contaminants are drawn off from the separation tank and the contaminated water is pumped as a fine spray into an upper portion of a stripping tower.

Abstract: A small-scale hydroelectric generator has a micro-hydro axial-flow turbine mounted in a lower end of a penstock, preferrably of the siphon type, through which water is diverted from an intake basin. The turbine comprises a stator section formed with an axial core providing an annular passageway having an outlet end in close proximity to a rotor of a coaxial adjacent rotor section. The blades of the rotor have a length equal to the internal radius of the passageway. A plurality of flaps are arranged in an expandable circle between the stator section and rotor. A float mechanism located in the intake basin follows the water level and controls the extended positions of the flaps reducing the water flow through the penstock in a predetermined relation to the water level. The annular passageway has fixed vanes directing the stream of water in a helical swirling motion of predetermined pitch to impinge upon the blades which are disposed to receive the stream at an optimum angle of 90.degree. .
Abstract: A penile prosthesis has a minor length proximal end member separable from the major length body member enabling insertion separately into the crus and the corpus cavernosum, respectively. An element of a quick engageable connector is formed on the adjacent ends of each member for joining the members together as a unit after each member is properly positioned in the patient. Several connectors are shown. Penile posture control is achieved in the major length body member by an axially extending multiple jointed spine within a silicone rubber casing. The spine is formed with alternate tubular and spherical links retained in an articulating assembly by an axial wire. Each spherical link is formed with a pair of diametric extensions projecting into the bores of adjacent tubular links and a diametric bore through the extensions through which the wire passes. The extensions serve to limit the articulation between adjacent links.
Abstract: An integrity indicator formed as an illuminable bead is combined with the pair of flat terminal blades of a miniature plug-in fuse and is positioned in a central window provided in the top wall of the insulator housing thereof. The housing defines a chamber having an open bottom and a central section with relatively narrow lateral sections in which upper portions of the blades are secured. A fuse-wire extends across the central section conductively interconnecting the blades. The illuminable bead has a pair of wire leads extending oppositely into the lateral sections of the chamber, each wire lead conductively contacting the upper portion of one of the blades and connecting the bead in parallel circuit with the fuse-wire. Clamping components formed on the interior of the top wall and on the upper portion of each terminal blade secure each wire lead in operative position.
Abstract: A toilet flush mechanism conserves water by offering a choice made by the direction of rotation of the flushing handle of either actuating a first lever initiating the discharge of a full tank of water or actuating a second lever initiating the discharge of a predetermined fraction of the water in the full tank, herein designated a mini-flush. A flapper valve controlling the discharge of water from the tank is opened by the actuation of either of the levers, is permitted to close in conventional fashion when the tank is empty upon first lever actuation and is closed by a downward thrust of a striker upon second lever actuation. A water level responsive device including a second float triggers the striker and acts independently of the ballcock valve and float which maintains the full level of water in the conventional manner.

Abstract: A proportional divider comprises a reference index located between a pair of variable indices and a sectionalized threaded spindle having opposite end sections with reverse threads and of different pitches in a ratio approximating 1 to 0.618. Each spindle section threadingly engages a support for one of the variable indices whereby rotation of the spindle simultaneously adjusts the distances between each variable index and the reference, the distances being maintained in said ratio which is known as the "golden proportion". In one form of divider, the supports for the variable indices are retained for movement along a straight track, the reference and variable indices being portions of pointers extending perpendicularly to the track, the reference pointer being fixed and the variable pointers being mounted on said supports. A plurality of interchangeable reference pointers and variable pointers provide versatility to the divider.
Abstract: Articles of jewelry with gems set in precious metal are cast by a modified lost wax method whereby each gem is retained in position in the investment mold after removal of the wax enabling the setting of the gem to be simultaneous with the casting of the precious metal. The wax model of the article of jewelry is molded with undercut grooves in the sidewall of the gem seat located to engage portions of the girdle of the gem for retention thereof in set position in the finished article. The wax for the model is formulated to provide resiliency to permit the gem to be snapped into position in the wax model prior to embedding the model with the gem set therein in investment material in the conventional flask. Curing time is reduced to approximately one half the conventional fourteen hours by precise control of predetermined time and temperature which also prevents marring of the gems during the curing of the investment and the casting of the precious metal.
Abstract: An electrically chargeable plate of predetermined surface area is retained in contact with the skin of each of two participants. An electrical conductor connects each plate to one of the two terminals of the audio output of one of the channels of a stereo amplifier while the other channel plays through its speaker. Physical contact between the participants completes the circuit enabling both participants to feel the modulated impulses of the sound as well as hear the output of the speaker on the other channel. Both plates may be worn by one person to experience a comparable feeling or one plate and an electrically chargeable wand used in place of or in addition to the other plate enables either one or two persons to participate.
