  • Publication number: 20130236237
    Abstract: A multi-section telescoping pole including a tubular first section having a female end and an interior which defines an axial path. A second section has a male end slidably engaged within the interior of the first section through the female end and being slidable along the axial path. An internal annular groove is provided adjacent a distal end of the pole section remote from a proximal end and having a button receiving opening in the annular groove. The annular groove is configured to capture the button when the first and second sections are telescopically extended so that once the button has been captured in the groove, all that the user need do thereafter is to rotate one pole section relative to another to align the button now captured in the groove with the button receiving opening to secure the two pole sections together.

  • Patent number: 8469423
    Abstract: A multi-section telescoping pole for manipulating a tool. Sections of the pole have apertures. A pinch safety locking assembly includes a button configured for movement by a digit on a user's hand to a first position by a first resilient member when received in aligned first and second apertures to restrain the second section from moving relative to the first section and to a second position against a resistance provided by the first resilient member and against an elastic stop to permit relative longitudinal movement between the first and second sections. The pinch safety locking assembly is additionally configured to facilitate assembly by movement of the button by use of an excessive force to a third position against a combined resistance of the first resilient member and the elastic stop to permit relative movement between the pinch safety locking assembly and the second section.

  • Patent number: 7406628
    Abstract: A method and device are provided that use a sequencer in the device to control interactions on an interface bus. The sequencer is programmed to interrupt a co-processor before execution of a command. Based on the interrupt signal and a stored error mode page, a false error condition is initiated by further programming the sequencer to operate abnormally. After recovery from the error condition, the sequencer is reprogrammed to operate normally.

  • Patent number: 6887325
    Abstract: A non azide gas generant composition of nitroguanidine and an oxidizer such as phase stabilized ammonium nitrate is provided. A gas generant having nitroguanidine and phase stabilized ammonium nitrate has many desirable characteristics such as little production of ash and the production of essentially toxic free exhaust gas. When nitroguanidine is compressed into a pellet it has needle shaped crystals that bend or distort. When the gas generant pellets are subjected to thermal cycling some nitroguanidine crystals will return to their native conformation resulting in pellet growth. To eliminate this pellet growth, nitroguanidine is passed through a vibrating ball mill. The media in the vibrating ball mill pulverizes the nitroguanidine into an amorphous crumb.

  • Patent number: 6839583
    Abstract: A disposable tip adapted for use in connection with an optical probe of an instrument. The tip includes a one-piece molded elastomeric base member having a boot and an opaque tissue-engaging surface. The boot releasably mates with and provides an interference/friction fit to the probe. The tissue-engaging surface surrounds and extends from the boot. A window in the base member extends into the boot to transmit light between the probe and tissue. A layer of optically transparent material covers the window on the tissue-engaging surface. Adhesive on the tissue-engaging surface of the base member releasably secures the probe to the tissue being analyzed.

A take-up element is mounted for rotation on the second jaw member. A latching mechanism is mounted on the second jaw member and is configured to inhibit rotation of the take-up element in a first direction. The take-up element is uninhibited by the latching mechanism when rotating in a second direction. A chain extends over the take-up element and has a first end attached to the first arm and a second end attached to the tension element. The chain is positioned wholly outside of and out of contact with the second handle member.

  • Patent number: 5593196
    Abstract: A telescopic hot stick or pole for manipulating a tool from a position a selected distance away from a workpiece wherein the hot stick includes a tubular first section having a female end and a predetermined non-circular cross-sectional shape. A second section has a male end slidably engaged within the first tubular section and a predetermined non-circular cross-sectional shape conforming in a close-fit relation to the shape of the first section to prevent significant relative rotation of the second section therein. A locking assembly maintains the second section in an extended position where locking is accomplished in response to a sliding of the second section to the extended position and may be disengaged to permit ready removal of the second section from the first section.
