Abstract: The chain saw tensioner of the present invention provides a sheath anchored at one end to the housing of the chain saw which sheath receives a tensioning shaft slidably therein. The tensioning shaft is interconnected with the housing by a tension screw and is slidably adjustable with respect to the sheath by actuating the tensioning screw. The tensioning shaft and the sheath have matching and aligned slots that cooperate to receive a sliding bolt therethrough. The sliding bolt is interconnected with the blade of the saw and, by actuating the tensioning screw, it may be moved forward with respect to the housing of the saw to move the saw blade forward to tension the chain. Included within the tensioning shaft is a spring interconnected with a bolt rest for receiving and supporting the sliding bolt. The spring provides a bias which acts on the bolt to bias the bolt, and accordingly the saw blade, forward with respect to the housing to tension the chain.

This peripheral wall portion extends to the peripheral portion of the round portion of the diffuser.

Abstract: A cleaning tool for telephone jacks is provided which includes a hollow cylindrical body and a polishing wheel having an internal aperture mounted within the body. The jack nose of the telephone jack is cleaned in the aperture. The wheel is secured in the body by a washer and lock nut arrangement. Both the washer and the lock nut also have apertures therein which are mounted concentric with the aperture in the polishing wheel so that the jack nose can be passed through the wheel and through the aperture in the washer, and into the cavity in the lock nut so that the entire length of the nose can be cleaned in the wheel. The cavity provides space for the residual matter removed from the cleaning site to be deposited for retrieval at a later time. A handle attached to the locking nut manipulates the device.

Abstract: The present invention sets forth an automatic gluing and conveying system for use with an automated clamp tightener and flattener system in which the conveyor system is capable of moving transversely to the path of conveying in order to accommodate movement of portions of the clamp carrier which interfere the conveying path. An electronic controlling means controls the movement of the conveyor along the conveying path, movement of the conveyor perpendicular to the conveying path, and coordinates movement of the clamp carrier. Also provided is a method for gluing segments of wood to be formed into panels by a gluing process which is controlled by an electronic control system which coordinates movement of the conveyor along a conveying path and movement of the conveying means perpendicular to the conveying path and movement of a clamp carrier apparatus which overlaps the conveying path.

Abstract: A linear gas generant to be used in, for example, a gas generator for rapidly launching a flier such as a rocket or for rapidly inflating an air bag in a motor vehicle characterized by disposing a fibrous substance, such as copper, silver, aluminum or carbon, along the axial direction thereof. This linear gas generant can be stably deflagrated under a lower ambient pressure, irrespective of a large specific burning area.Disclosed further is a filter structure for a gas generator to be used in an air bag restraint system, which is produced by winding a continuous high-tensile-strength fiber bundle or yarn at a predetermined pitch around an outer surface of a member (a gas generation member) comprising ignition means and gas generation means actuated by the ignition means. This filter structure attains the reduction in weight of the gas generator.

Abstract: A product, in particular a shoe, apparel, a ball or a fishing lure, incorporating an impact sensing element made from polymeric piezoelectric material. In response to impact, the piezoelectric material generates an electrical signal to a battery-powered light- or sound-emitting unit or to an information display device which is at least partially molded into or contained in the product, thus causing circuitry to energize the light- or sound-emitting device from the battery or to display information on the information display device. In some embodiments involving light-emitting devices such as LEDs, the light is conducted to an outside surface of the product directly through the LED or via one or more optical fibers. A shoe can be provided with numerous light-emitting devices, one or more impact sensing elements, a temperature sensor and appropriate circuitry to process the impact and temperature information.

Abstract: A shoe comprising a sole portion having peripheral edges and at least one cushioning element comprising a chamber having flexible walls filled with a liquid composition, wherein the chamber includes a plurality of partitions for directing flow of liquid from one portion of the chamber to another portion of the chamber. Preferably, at least one partition is a gating means responsive to a differential in liquid-pressure for enabling the flow of liquid to the chamber portion of lower liquid pressure. The cushioning element overlays the sole portion. A portion of the cushioning element extends to a peripheral edge to provide cushioning support to a foot of a wearer at the peripheral edge. Preferably the extending portion of the element has substantially transparent walls, whereby the liquid composition can be viewed.

Abstract: A limb supporter apparatus supports a patient's elbow on support pegs that extend under the condyles of the humerus bone for positioning the ulna bone for bone testing. The ulna extends over the humerus and is positioned close to the skin for testing. The wrist is supported in the apparatus of the present invention between two vertical support pegs to secure the wrist in a vertical position and to prevent radial movement of the wrist. This apparatus properly positions the ulna above the humerus and allows for consistent, reproducible results during testing performed on a bone. The elbow and wrist supports extend from horizontal members which are supported by vertical support members. The vertical support members are positioned on a horizontal support member which is pivotally connected to a base member. The base member may be secured to a table by attachment bolts.

Abstract: An expandable baseball hat and cover adapted to expand and conform to differently shaped heads or protective devices. The hat includes a first flexible material which has an inner surface, an outer surface and a peripheral edge to form a skirt portion. The inner surface of the first material is provided with two tab members, each of which has coacting fastening means for releasable engagement with each other. The tab elements are engaged to gather the flexible material for a snug, conformed fit to the wearer's head. The expandable hat can be used in combination with a rigid shell, such as a batting helmet. The expandable hat is fitted over the shell for the skirt to snugly engage the peripheral edge of the shell without other fastening means. The skirt and inner surface of the shell are provided with second coacting fastening means in registration for releasable engagement.

Abstract: A combination headgear and poncho is provided which includes a hat having a crown portion with a liner disposed therein for forming a compartment in which the poncho is contained. The liner is formed with an aperture through which the poncho is extracted from or inserted into the compartment. Complimentary fastening means, such as hook and pile materials, are disposed at the liner along the aperture to secure the compartment. The crown portion is also provided with gathering means which operatively adapts the crown portion to snugly fit the wearer's head when the poncho is contained in the compartment or when the poncho has been removed from the compartment and deployed, resulting in the weight of the crown portion being reduced.

Abstract: A time indicator is provided that changes color or produces an image or information after a specific time interval. The time indicator includes a base substrate with colored dye deposited on a first surface; and a substrate having an adhesive on a first surface thereof, the adhesive positioned at discrete locations on the first surface of the substrate. The substrate and the base substrate are put into adhesive contact. The adhesive contacts and coacts the colored dye to dissolve the dye and permit the dye to migrate through the adhesive to cause a color change visible through the substrate. The discrete adhesive inhibits lateral migration of the dye to preserve the image or information of the dye in a clear and/or understandable condition.
