Abstract: A hitch for connecting the rear of a garden tractor to the rear of a garden tiller of the type having one or more tines which rotate in the direction of normal travel of said tiller comprising a beam, a bracket and an arm aligned in an adjustable triangular shape being in a substantially vertical plane for the controlled pulling of the tiller by the tractor in a direction opposite to the direction of rotation of the tiller tines thereof.

Abstract: A deburring drill bit having a shank, an elongated shaft, a drill bit head having forward drilling surfaces formed in the head, and rearward deburring surfaces formed behind said forward drilling surfaces, whereby drilling and deburring can be performed in a single operation, the drilling surfaces having a first longitudinal axis and the deburring surfaces having a second longitudinal axis not coincident with said first longitudinal axis.

Abstract: A fishing float for catching fish during absence of the fisherman and indicating a caught fish comprising a buoyant body having a flat top surface and a flat bottom surface parallel thereto; a concentric central aperture through the float from top to bottom; a first flat side surface on the periphery of the float; and a second flat side surface on the periphery of the float; located opposite to and parallel to the first side surface.

Abstract: A restraint system for use in maintaining a patient on a patient supporting structure comprising, a harness adapted to fit on the torso of the patient, a flexible strap assembly connected to said harness, said strap assembly having a plurality of openings therethrough at spaced apart positions axially of said strap assembly, a flexible connector adapted to selectively extend through any selected of said openings in said strap assembly, and an attachment for connecting said flexible connector to the patient supporting structure.

Abstract: A birth safety net to prevent the dropping or falling of a new born child as it exits the birth canal comprising a fabric body, five sides, five corners and means for securring each corner to a portion of the birthing chair or birthing bed.

Abstract: A media loaded computerized sound emphasizer device for synchronizing a light show performance to music based upon active computer control instead of conventional passive sound control or inaccurate manual comprising a computer and media playback unit controlled by the computer, a power distribution unit, and one or more light units, wherein each song used with this apparatus cooperates with an individualized program thereby allowing the audience to experience the audio detail through the visual sense.

Abstract: A utility bin for enclosure in structures such as furniture, cabinets, and closets for storage of such objects as magazines, newspapers, books, wearing apparel and linen. As storage for wearing apparel and linen, forward and rear pivot arms on each end of the bin control the movement of both the upper and the lower area of the bin outward to a tilted position. As storage for magazines, newspapers, and books, the bin also has an automatically positioned panel for support of upright placed contents. Rollers attached to the support panel contact a downward sloping rear to front surface such as the bottom to effect movement forward for contact with the contents of the bin when the bin is placed in home position. Flexible retainers such as chains attached to the rear of the support panel and to the rear of the enclosure structure retain the upright support panel to the rear when the bin is moved outward allowing unobstructed access to the contents of the bin.

Abstract: A method is provided for removal of surface oxide from a continuously cast copper bar preparatory to inline hot rolling, wherein solidified bar continuously advancing from a continuous caster is directed to a continuous hot rolling mill, comprising: passing said advancing bar, being at hot rolling temperature, through a spray zone of selected quench capacity and impulse, such that for each segment of said bar passing through said spray zone, said oxide is quenched to a black heat but is not ablated and said underlying bar is subjected to a shallow quench; said spray zone being situated in close proximity to but selectively spaced upcourse from the first rolls of said hot rolling mill such that there is insufficient time for substantial reheating of said quenched oxide during the approach to said first rolls; whereupon as quenched segments of the advancing bar progressively approach said first rolls and said underlying bar begins to deform just prior to roll contact, said oxide spalls off the bar surfaces subs

Abstract: A reading and spelling teaching system primarily for auditory dyslexics and visual dyslexics having a phonogram classification board with the seven categories of vowel sounds depicted, phonogram cards with the major vowel sounds of each vowel group (a, e, i, o, u), consonant cards depicting through pictures the consonant sounds and consonant blends/consonant diagraph sounds, and a teaching device in the form of a game for reinforcement of the phonograms.
