Abstract: A toy comprising a frame formed from a continuous length of rigid elongated wire having ends. The wire between its ends is bent to form multiple curves to give the frame a three dimensional configuration with top, bottom and sides. The curves of the wire at the bottom lie in a plane to form a flat supporting surface for the frame. A plurality of beads, with a hole in each bead are movably supported on the wire, with the wire passing through each hole. The holes are sufficiently large to permit the beads to freely slide over the curves of the wire between its ends. In alternative embodiments, stop means may be provided at the ends of the wire to hold the beads on the wire or the ends of the wire may be joined by appropriate means, in each case to provide a continuous, endless run for the beads over the entire frame.

The device comprises a short length of flat bar to be fastened directly to an internal portion of a door frame at the height of a latch bolt receptacle so that a relatively large area of a surface of the bar provides a solid buttress support contact for the latch bolt when in the latch bolt receptacle, the bar thereby serving as a high strength, adjustable latch bolt keeper. Fasteners and holes in the bar provides for connections to the door frame, the cover-plate-and-strike, and to a safety chain as may be required.

Abstract: An auger for use in drilling into the earth under rotative movement in one direction of rotation, the auger having a cylindrical stem and a helical flight extending along the length of the stem, the helical flight being defined by adjacent segments of opposite flight orientation. The auger of the present invention enables the drilling of fast holes of any conventional size to any conventional depth required in overburden and bedrock. It reduces the tendency of bore hole wall collapse through the use of bore hole material to stabilize the hole and reduces the amounts of drilling muds needed.

Abstract: A method of making hard rollers for commercial printing presses comprising the sequential steps of heating a cylindrical sleeve of plastic material until it reaches an elastic state, fitting the sleeve into position over a cylindrical metal core having an outer diameter slightly greater than the inner diameter of the cylindrical sleeve, and cooling the cylindrical sleeve. The method may be used to rebuild worn rollers and is simpler and more versatile than conventional methods of making hard rollers including electrostatic spraying of metal cores or securing plastic sleeves by means of adhesive or heating heat shrinkable polymer sleeves.

Abstract: A device for protecting bait impaled on a spike within a lobster trap or the like. The device comprises a flat body having a centrally disposed spike-receiving aperture for seating the device on the spike above the bait when impaled thereon. A plurality of protector spikes with sharpened points are secured to the body, the spikes downwardly and outwardly oriented about the body when seated on the spike. The device is particularly well-suited to deter seals from stealing the bait from within the trap.

Abstract: A fender for a wheel or a set of wheels for one side of an automotive vehicle, for controlling the wet weather spray and splash generated thereby when travelling on a roadway surface. The fender comprises a formed, rigid sheet mounted over and covering the wheels or set of wheels and downwardly curves at its forward and rearward ends. A removably downwardly depending skirt extends along the edges of the sheet. One or more air intake apertures in a forward, curved end of the sheet directs air from outside the fender to inside the fender and over the wheel or set of wheels covered thereby during forward movement of the vehicle. A spray shield in sheet form is adapted to be disposed above the roadway surface vertically depending form the rear of the rigid sheet and is spaced rearwardly from the vehicle wheel or wheels in a plane extending transversely to the vehicle.

Abstract: A safety cap is provided to be worn on the head of a diver such as a scuba diver or snorkelor, for protection against contusions, abrasions, incisions, lacerations and the like. The safety cap comprises an exterior, unitary shell of part-spherical configuration made of flexible plastic, to provide a smooth outer surface. The flexible plastic is of sufficient strength to resist small impact loads. A continuous interior liner of open cell foam is secured within the exterior shell to act as padding and to provide a thermally protective layer for the diver's head. A pair of straps are provided, each one being secured to a side of the shell. Each strap is of a length and provided with securing means respectively for looping and securing about a proximal portion of a head strap of diver's face mask or goggles when worn by the diver. The cap is easy to wear and provides significantly improved protection for divers against minor, low impact head injuries.

Abstract: A method and apparatus for sound reproduction wherein a load and dispersion cell is provided. The cell comprises walls to enclose transducer means. The transducer means have front and back surfaces and are secured within the walls. The walls form an elongated narrow sound emitting slot. The slot is spaced from and extends parallel to and over the lengthwise center of the front surface of the transducer means. The slotted cell spreads the field of sound generated by the transducer in a direction perpendicular to the longitudinal axis of the slot and loads the transducer to lower its resonance. The cell in accordance with the present invention extends the low frequency response and provides more uniform dispersion of sound.
