Abstract: A nostril enlarging device comprising a generally U-shaped member having a pair of upstanding legs with each leg having a posterior protuberance for locking into the cavity in the lower posterior nostril wall. Each leg also includes an anterior protuberance located upwardly from the posterior protuberance, so that the angle connecting the two is at approximately 45 degrees to the vertical center line of the device.

Abstract: A stove having a combustion chamber surrounded by four sides and a top and having a warm air conduit extending between opposite sides and opening outwardly of at least one of the sides. Where the stove is to utilize natural convection, the conduits open outwardly of both the sides of the enclosure. An opening is provided in the top or bottom of the warm air conduit remote from its outlet or outlets for effecting draft thereto. A preferred embodiment has two such heating conduits at right angles to each other and with an opening therebetween to further increase draft through the conduits. In the case of forced convection, the conduits need only open from one of the sides.

Abstract: The invention recognizes that the areas of the load carrying bed of a pick-up truck between the rear wheel wells and vertical framing are not particularly accessible for payload. The ballast fits into this space in a manner which automatically locks it in place by reason of its shape. The preferred arrangement can be filled with sand so that its weight can be inexpensively and conveniently changed to fit changing circumstances.

Abstract: A control circuit utilizing: a counter which provides first and second output signals at spaced apart time intervals and delay means for stopping and starting the counter; and switch means having start and stop inputs and an output connected to the delay means of the counter. The switch means, being arranged to start the counter when the start input is energized, and being arranged to stop the counter when the stop input is energized. The stop input of the switch means being actuated by the first counter output signal.

Abstract: A homing system utilizing a loop antenna positioned at approximately 45.degree. to the vertical to provide an electromagnetic field having both horizontal and vertical components. These signal components are picked up by a vertical loop stick antenna alternately connected to one of two bifilar wound coils of a horizontal loop stick antenna to provide alternating signals. The strength diagrams for the alternating signals are cardioid shaped and are arranged back to back with their null point passing through the intersections of the back to back signals. The null point of both antenna systems occurs when the horizontal loopstick antennas are at right angles to the electromagnetic lines of force; and any time that the horizontal loop sticks are turned at an angle relative to their null point, a difference in signal strength exists between the two antenna systems. This is picked up, and is amplified at separate time intervals by a common amplifier.

Abstract: A telephone isolation device having a latching relay operated switch in one of the telephone conductors which when the relay is actuated brings a voltage dividing branch circuit that includes a restoring coil of the relay into parallel with a subscriber's telephone. If the telephone is connected and off of the hook, the low impedance of the telephone keeps the flow of current to the restoring coil below an operable value. When the telephone is placed on the hook, all current thereafter passes through the restoring coil to again connect the telephone to the telephone conductors. The disconnect coil of the relay is actuated by applying a positive 100 volt DC current to both lines of the telephone system.

Abstract: A method of preparing glass fibers having a surface enriched by zirconium dioxide thereon, comprising the steps of: applying an aqueous solution of zirconyl carbonate to the surface of the glass fibers, keeping the fibers wetted under ambient conditions for a period of time to effect ion exchange with water extractable ions in the surface of the glass, and evaporate the water to leave the coated glass fibers. The coated glass fibers are especially suited for reinforcing cementitious materials.

Abstract: A material sensing device comprising a flexible or collapsible tube with a light sensitive device therein which receives light through the tube from a spaced apart light emitting device. The signal from the light sensitive device is amplified and used to operate a silicon controlled rectifier that snap actuates a solenoid operated switch. The invention includes an amplifying circuit in which the amplifier is the load for the silicon controlled rectifier and a generally fixed bias is provided to the gate of the SCR with the result that the circuit automatically resets the SCR during normal operation.

Abstract: Nonlocking plastic containers having shoulders that are spaced uniformly along the outside of a container for abutment with a plurality of shoulders on the inside of another one of the containers into which it is nested. The shoulders divide the container into a plurality of segments of uniform height and these segments are preferably tapered by an angle that is no greater than will cause the outside diameter of an outside shoulder at the bottom of a segment to be greater than the inside diameter of the inside shoulder at the top of a segment. The shoulders may be rounded in which case at least three abutments are provided to insure that the inside and outside rounded shoulders of nested containers will stay opposite each other.

Abstract: A rattle free window having a sash balance that is provided with a sash hook that is connected to a slide by slot and pin means so arranged that the weight of the sash thereon cams the slide laterally against the window jamb. The sash balance may also include a novel clip which both fixes one end of the balance spring to its housing and also attaches the housing to the window jamb. The window may also include a ramp clip which automatically catches the slide when the sash is raised so that further raising of the sash can lift the sash off of the novel sash hook and slide structure.

Abstract: A honing template comprising longitudinally extending fingers adapted to surround a hone and the ends of which carry template segments having inner abutment surfaces that are spaced to abut non abrasive surfaces that are in line with the stones when the stones are expanded to the finished diameter of the cylinder being honed. The inner abutment surfaces of the segments have a radius at least as great as the maximum radius of the cylindrical surface to be honed. The fingers have a tapered surface that is abutted by an annular ring which is wedged over said tapered surfaces to adjust the radial position of the template segments.

Abstract: A "short turn" vehicle having front and rear, centerline mounted, power driven, steerable wheels, and a pair of outrigger stabilizing wheels that are mounted on a rigid frame which is restrained against all but vertical movement relative to the frame. The vehicle is capable of zero radius turns under full load. The vehicle is ideally suited as a conveyance of rotary mowers since the vehicle's wheels "guard" the rotary mowing unit and three preferred arrangements thereof are shown and described.

Abstract: Means for providing a terminal to existing cartridge fuse installations. The preferred means is a clip comprising a split cylinder which fits between one end of a cartridge fuse and its holder and which contains a terminal extending at right angles to the split cylinder. In another embodiment the terminal which extends at right angles to the fuse is made as an integral part of the end cap of a cartridge fuse.

Abstract: The trapping apparatus has a tether coiled around a hub in a housing. The hub is biased to foreshorten the tether, by a spirally coiled spring that is positioned to one side of the hub portion on which the tether is wound. The spring is contained within a hoop that may be a portion of the hub to aid assembly. A latch mechanism is provided to release the hub when a caught animal tugs on the tether. The latch mechanism is such that it will not latch again until the tether is completely retrieved.
