Abstract: An electronic circuit means for automatically disconnecting an off-hook subscriber's first telephonic signal sending and receiving terminal device which is in an off-hook mode when a second terminal device is taken off-hook. The disconnector circuit means has voltage sensing means, current sensing means and line disconnecting means. The voltage sensing means senses a voltage across the current sensing means and when at a pre-determined level turns the current sensing means on allowing current to flow through the first terminal device. When the second terminal device is taken off-hook, the voltage across the loop circuit drops and current flow through the current sensing means drops. When the current drops to a pre-determined value, the current sensing means actuates the line disconnecting means and shuts off the current flow through the first terminal device.

Abstract: An automotive step-turbine engine comprising in combination a primary power turbine assembly, one or more power boost turbine assemblies and a power output demand sensor for sequentially placing in service the one or more power boost assemblies as additional power output above that capable of being economically produced by the primary power turbine assembly is required further sequentially taking the power boost turbine assemblies out of service in reverse order when the additional power is no longer required. The primary power turbine assembly and the power boost turbine assemblies are geared together synchronously and run at the same velocity. The assemblies each have an air compressor unit geared directly to the respective assembly for pumping air into burner units, one for each of the assemblies.

Abstract: A comfort cushion for infants comprising in combination a fluid filled flexible elastic hermetically sealed infant supporting mattress; a pulsating fluid pump means having mattress inlet and outlet fluid conducting conduits communicating between the pump means and the mattress for circulating a substantially non-compressible fluid through the mattress; and an infant heart beat and breathing alarm means having sensor means embedded in a mattress infant supporting surface for actuating an alarm means external to the mattress if an infant supported on the mattress were to stop breathing or its heart were to stop beating or if either breathing or heart beat were to change such as to indicate peril to the infant. The mattress inlet conduit has a pressure activated valve within the mattress which opens at a pre-selected fluid flow pressure and closes upon the pressure dropping below a lower pre-selected pressure to simulate sounds and fluid movement conditions a pre-born infant experiences.

Abstract: An emergency locator system for locating and retrieving sunken vessels and vessels in distress comprising in combination a base, a buoyant float releasably mounted thereon and a long line connecting the base and float. The base is adapted to be mounted on an external surface of a vessel in spaced apart relationship thereto to permit fluid to circulate between the vessel surface and the base. The base comprises a hydrostatic pressure sensing-diaphragm activated float holding and trigger release assembly. The diaphragm is located on a lower surface of the base adjacent the vessel surface when the base is mounted on the vessel. The base has U-shaped grapple cables attached to it and the grapple cable ends may also be attached to the vessel beneath the mounted base. The float is adapted to be releasably mounted on the base and upon the base float being subjected to a pre-selected external pressure the float is released and floats to the water surface being connected to the base by a long locator line.

Abstract: A case for carrying and storing compact cassettes having a cassette tray and rearwardly hinged thereto a tray cover. The tray has a plurality of cassette positioning rib sets for positioning and retaining cassettes inserted into the tray in parallel transverse arrangement with a cassette recorder coupling edge parallel to the tray bottom and the cassette sides portions defining the cassette recorder coupling means of each inserted cassette touching or nearly touching adjacent cassettes. The case has a latch for openably latching the tray and tray cover in closed position and a carrying handle.

Abstract: A Heads Down Golf Practice Device having a resilient tubular golf tee member mounted in and protruding upwardly from a resilient, flat tee support structure base. The base includes a light emitting assembly having a light visible through the tee interior portion of the resilient tubular golf tee and mechanical indexing elements for randomly selecting a color of the visible light. The support structure is placed in front of a golfer on a relatively flat surface in a desired location, a golf ball is placed on the tubular tee thereby covering the light which is otherwise visible through the tee interior at the tee top, a color is randomly selected by the golfer and the golfer swings his golf club striking the ball setting it in flight and observes the light color after the ball is struck and the club passes over the tee, if the golfer's shoulders, head and eyes are positioned correctly the instant the golf club strikes the ball and passes over the tee.

Abstract: A rotary internal combustion engine comprising in combination rotary air compressor and rotary power sections having cylindrical chambers having rotatably mounted internal to each chamber a movable vane rotor assembly.Each movable vane rotor assembly comprises a hollow cylindrical rotor having a movable vane assembly therein having a plurality of three or more vane pivotably connected to a floating vane shaft, said vanes being in sealable abutment with internal surfaces of said cylindrical chambers exterior to said rotor. Consecutive compartments are defined by adjacent vanes in combination with inner chamber and outer rotor and vane surfaces. Compressor and power rotors are connected to common shafts which extend through cover plates which partially enclose the compressor and power chambers.

Abstract: A method for extracting a mounted anchor bolt secured within an anchor bolt mounting cavity in a mounting member, said method comprising inserting into a central opening of a central cylindrical hole in the anchor bolt an anchor bolt extractor tool and screwing into said anchor bolt said tool thereby releasing the anchor bolt from a conical wedge engaging a bottom portion of the anchor bolt within the mounting cavity and thereafter lifting the anchor bolt from said cavity.

Abstract: A Journalist Teaching Aid for Journalists is provided which comprises in combination: a plurality of master layout boards constructed of a material such as glossy paper, mylar or the like to permit readily detachably mounting adhesively backed materials thereon, the master layout boards are used to simulate pages of publications such as newspaper, magazines, tabloids, books, and the like; adhesively backed strips of materials such as glossy paper card stock, plastics such as mylar and the like having a plurality of said strips covering a plurality of dimensions for simulating flags, nameplates, logos, headlines, mastheads, artwork and the like used in publishing said pages of publications; adhesively backed strip holders for detachably mounting said strips thereon when not in use; and a plurality of miniature card stock layout boards for use by the journalist in drafting thereon a preliminary page layout.

Abstract: A bait holding assembly having in combination a swivel means attached to a clip which is in turn attached to a bait clamping means. One or more relatively short fishing lines are attached to the clip and carry fish hooks that are embedded in the bait when clamped. The bait holding assembly is particularly well suited for use with opened bivalves such as muscles and the like as bait, said bivalve being clamped in said clamping means and said hooks or hook being embedded in the flesh of said bivalve. The clamping means is so constructed as to maintain the bivalve in a fully open position.
