Abstract: A cable lock is incorporated into the grip of a ski pole, using the base of the grip as a lock housing. Each ski carries an engaging member that can be fastened into the lock housing to attach each pole to a ski, such as for theft prevention, storage or carrying. In addition, the cable lock wraps the poles and skis and can attach them to a fixed object. The lock housing covers the mounting of the engaging member to the ski, which prevents tampering while the skis and poles are locked.

Abstract: A rack for drying or curing items can be disassembled for storage or transportation. The rack includes a pair of rack units, each rack unit including a base, an upright and a series of elongated members, or poles, on which the items can be supported above the generally flat surface on which the unit rests. The base includes three legs that engage the flat surface. The series of poles is supported by the upright. The upright is hollow and can be used to store the poles and base legs. A cap is provided to close the upright to keep out moisture and dirt when the rack is in use, and to ensure that the poles and base legs remain in the upright, and are protected, during transportation or storage of the unit.

Abstract: A self-defense knife has a handle and a blade. A user of the knife preferably holds it by the handle such that the blade extends toward the elbow of the user. The blade has a blunt edge and an opposite sharp edge. The knife is preferably held, more particularly, such that the blunt edge rests against the soft underbelly of the user's forearm. By holding the knife that way, the user is less likely to harm him or herself during use, and is also more likely to maintain the sharp or cutting edge in proper position for fending off an aggressor. The blunt edge is given a shape and arrangement that generally defines a reverse curve of the curve defined by the user's partly flexed wrist and forearm. The curve of the blunt edge thereby closes up a possible gap that could exist between the blunt edge and forearm. That way, an aggressor cannot grab the wrist of the user without also grabbing the sharp edge.

The housing includes a sliding seal between the movable ends to permit relative motion between the ends while maintaining a sealed relation therebetween. Each movable end includes an aperture and a corresponding fastener for engaging the adjacent portion of the coil bundle to draw the coiled bundle against the respective end, thereby permitting removal of one end of the housing upon removal of a single fastener.

Abstract: A fence system having treated wooden posts set in concrete at spaced-apart locations. Galvanized metal stringers extend between the posts and engage the post at a mounting surface. The mounting surface defines a plurality of vertically-elongate slots through which fasteners extend. Pickets are secured to the stringers and are vertically oriented. The stringers are secured by fasteners such as screws. Preferably the stringers are formed from HDPE and expansion and contraction of the pickets is accommodated by the slots in the mounting faces of the stringers. The pickets are formed by grinding waste plastic and adding UV inhibitors and color if desired. The ground plastic material is extruded under heat and pressure and the desired surface treatment applied to simulate the appearance of natural wood fencing. The surface-treated extrusion is cut to the desired length to form individual pickets.

Abstract: Each board of a multi-board panel is gripped and registration is established by engagement with tooling of the transfer arm of an in-line machine in preparation for a routing process by which the boards are to be liberated from the panel (depaneled). The tooling supports each board and maintains registration therewith during liberation of the board from the multi-board panel and also during transfer of the liberated board to a selected one of several sites of a subsequent station via repositioning of the transfer arm. In one embodiment of the invention, registration is accomplished by inserting lengthwise-bifurcated locator pins into corresponding locator holes in the boards and expanding the bifurcated legs into locking engagement with the panel by longitudinal displacement of a tapered rod which is disposed between the legs.

Abstract: In a typewriter ribbon cartridge, it is necessary to maintain tension on the span of ribbon extending outside the cartridge to prevent tangling and to insure high print quality during machine operation. One technique for insuring that adequate tension is maintained is disclosed herein as an anti-backup back check device. Connected to the takeup spool of the ribbon cartridge is a disc member supporting thereon a pair of thin flexible resilient arms with outwardly oriented pointed ends. These ends formed in the shape of points engage ratchet teeth formed around the interior surface of a cylinder. The cylinder is formed as a part of the ribbon cartridge and, thus, is permanently positioned and fixed with respect to it. As the takeup spool disc and arms are rotated by the ribbon feed mechanism, the arms will flex and permit a rotation of the disc and takeup spool with a minimal drag force.

The assist unit is carried on the axle opposite the outside wheel face and substantially conforms in contour to that face. Alternate friction members may be cylinders that are applied to the wheel face offset from the axle, and alternate reservoirs may be attached to the vehicle body or to a remote activating hand lever.

Abstract: A power supply and firing control circuit for a strobe lamp has a capacitor means for providing electrical power to the power electrodes of the strobe lamp for discharge through the strobe lamp. A transformer has a pair of secondary windings, one of which is connected to each of the power electrodes of the strobe lamp in series with the capacitor means. The firing pulses provided by the secondary windings of the transformer are of opposite electrical polarity. The absolute voltage differential between any portion of the circuit and ground potential will be minimized and energy losses thereby reduced. Additionally, the circuit provides substantial improvement in ionization effectiveness, thereby permitting the secondary turns of the transformer to be reduced in number and the transformer size and weight reduced correspondingly.
