Abstract: The present invention is directed to a sperm flagellar energy carrier, SFEC, antibodies specific for the SFEC and the use of the SFEC protein to identify antagonists of SFEC activity. SFEC is believed to be essential for sperm motility, is localized to a specific region of the sperm, and thus antagonists of SFEC activity are anticipated to have utility as contraceptive agents.

Abstract: A method and device to conform with the glans penis to recover ejaculated semen completely, to prevent the loss of initial sperm rich epididymal fractions, to avoid the use of a condom for masturbation, to eliminate the multi-step transfers of semen following ejaculation that are common with current methods, and to provide a single device that contains a semen collecting chamber that fits onto a glans penis. The device provides a storage and measuring reservoir, an optional cap, and a vertical stand in one integrally formed module in a sterile pack.

Abstract: The present invention is directed toward apparatus and methods for rolling and distribution of fencing material, and is particularly suited for flexible fencing such as metal and plastic fencing, whether linked, boxed, webbed, barbed, electrified, or otherwise configured. The apparatus of the invention can be mounted on a skid loader, tractor, or other lifting vehicle, whether onto the bucket attachment or onto the forklift attachment of such a lifting vehicle. The apparatus has a wrapping shaft that is pivotally or hingedly mounted to supporting framework. The shaft is connected to a motor for powered rotation of the shaft. The apparatus also has one or more tensioning rollers that flatten the fencing and position it during uptake or distribution of fencing by the wrapping roller. The supporting framework has guides that orient and position the fencing as it passes through the apparatus. The invention also provides methods of recovering, as well as distributing, fencing using the apparatus.

Abstract: The present invention is directed to a family of testis specific proteins (SLLPs) that share high sequence identity to lysozyme-C proteins. The application encompasses compositions comprising the SLLP proteins, antibodies specific for the SLLP polypeptides and the use of the SLLP polypeptides and antibodies directed to such peptides as contraceptive agents.

Abstract: The present invention is directed to a human egg specific protein (ePAD), antibodies specific for the human egg specific protein and the use of the ePAD protein to identify antagonists of ePAD activity. Antagonists of ePAD activity are anticipated to have utility as female contraceptive agents.

Abstract: The present invention relates to two novel, testis-specific proteins (C19 and C23) that are lysozyme paralogues. The proteins are believed to play a role in capacitation of sperm and the fertilization of the ovum. Therefore these compounds make ideal targets for the design of contraceptive agents. The C19 and C23 proteins can also be modified to establish lysozyme activity and the modified proteins can then be used in all applications that currently exist for lysozymes.

Abstract: The present invention relates to a family of testis specific kinases (the tssk family), nucleic acid sequences encoding those kinases and antibodies against the kinases. The invention is further directed to the use of the tssk 4 kinase and other members of the tssk kinase family as targets for isolating specific inhibitors or antagonists of tssk kinase activity. Such inhibitors are anticipated to have use as contraceptive agents.

Abstract: A washer extrudes indicating material of varying colors depending on the compression force applied to it by providing a first and second surface having respective bumps and indentations. The compression force on the washer is equal to the tension of a bolt passing through the washer. The indentations in the second surface are filled with a solid extrudable colored material. By making at least a first bump taller than at least a second bump, the first bump will compress before the second bump, causing it to extrude the color material in its corresponding indentation before the second bump does the same as the tension in the bolt is increased. By making the material under the first bump a different color than the material under the second bump, an operator can determine which of two desired tensions the bolt has reached.

Abstract: A direct tension indicating washer including a body having an internal opening formed therein and at least one arched tab connected to the body. The arched tab has a fixed end integral with the body and a distal end movable with respect to the body. Indicia is formed on the arched tab and when the direct tension indicating washer is tensioned, the arched tab moves away from the body. Alignment of the indicia with a reference indicates proper tension. Another embodiment of the invention is a direct tension indicating washer having a body having an internal opening formed therein and at least one arch connected to the body. The arch has a first end integral with the body, a second end integral with the body and an intermediate portion between the first end and second end. The intermediate portion is positioned above a top surface of the body.

Abstract: A direct tension indicating and maintaining washer has a first surface having at least one protuberance formed thereon and a second surface having at least one indentation formed therein opposite the protuberance. The inner diameter of the direct tension indicating and maintaining washer has an inner diameter wall meeting the second surface at an inner diameter edge. The outer diameter has an outer diameter wall meeting the second surface at an outer diameter edge. The inner diameter edge and the outer diameter edge lie in different planes. This causes the flattened direct tension indicating and maintaining washer to exert force against a bolt and maintain bolt tension. An alternative direct tension indicating and maintaining washer includes indicating material positioned in the indentation and a channel formed in the second surface leading from the indentation to the outside diameter of the direct tension indicating washer.

Abstract: The back EMF generated in armature coils is substantially balanced by causing the coils located a greater distance from the axis of rotation of the armature to have fewer turns than the coils located closer to the armature axis of rotation. Alternatively, rather than decrease the number of turns in the coils, the same balancing affect can be achieved by increasing the electrical resistance of the coils located a greater distance from the armature axis of rotation.

Abstract: A brushless direct current motor is provided with a rotor having a rare earth magnet within a nonferrous cylinder and a pair of coil windings which are air wound. To effect rotation of the rotor, current through the coils is controlled to rotate the resultant magnetic flux generated by the currents through the coils so that the rotor attempts to align itself magnetically with the resultant flux from the coils. Both coils are simultaneously energized and the polarity of current flow through the coils is reversed in such a manner that there is a current reversal through only one of the coils whenever the current is switched. Coil switching is directed by a triggering magnet fixed on the rotor shaft, which magnet operates Hall effect switches. The Hall effect switches in turn operate power switches to apply the correct voltage and polarity simultaneously to both windings.
