Abstract:
A method is provided, to render non-hazardous, surfaces which are coated with lead-based paints. A composition comprising an aqueous mixture of hydrogen peroxide, ammonium hydroxide, nitric acid and acetic acid is poured on the surface and, after a time, water is poured onto the surface to remove the lead-based paint. The method is effective on surfaces which may be comprised of wood, metal, concrete, wallboard or plaster without destroying the integrity of these surfaces.
Abstract:
A correction device for typewriters and the like, including a material, preferably in liquid form, maintained at a predetermined pressure within a container. The container outlet is coupled through a narrow elongated tube whose dispensing end is positioned upon the typewriter carriage or other device so as to be located immediately across from the last printed character or other symbol. An operating switch activates an electronic circuit for dispensing a measured amount of the material over the last printed character, the color of said material being the same as the paper being printed upon to provide the same effect as erasure of the character. The dispensing of the measured dosage may be accomplished either by electronic or mechanical means. The erasure means may be provided as an integral part of the typewriter unit or as an independent stand-alone accessory.
Abstract:
A wellbore servicing apparatus, comprising a first mandrel movable longitudinally along a central axis and rotatable about the central axis, an orienting member configured to selectively interfere with movement of the first mandrel along the central axis, and a second mandrel connected to the first mandrel and configured to rotate about the central axis when the first mandrel rotates about the central axis. A method of orienting a wellbore servicing tool, comprising connecting an orienting tool to the wellbore servicing tool, identifying a predetermined direction, increasing a pressure within the orienting tool, rotating a portion of the orienting tool in response to the increase in pressure within the orienting tool, and rotating the wellbore servicing tool in response to the rotating of the portion of the orienting tool.

Abstract:
A connector which joins two opposing sections of coil tubing or coil tubing to coil tubing tools so as to enable torque applied from one section to be transmitted to the other section is provided. The connector employs varying width and depth grooves into which portions of the sections of coil tubing are deformed so as to create the torque transmitting connection between the connector and sections of coil tubing. Each of the grooves have a narrow width portion and a wide width portion and corresponding shallow depth and deep depth portion. The narrow width portion of one of the grooves is approximately 180° out of phase from the narrow width portion of the other varying width groove.
Abstract:
Enclosed re-programmable non-volatile memory cards include at least two sets of electrical contacts to which the internal memory is connected. The two sets of contacts have different patterns, preferably in accordance with two different contact standards such as a memory card standard and that of the Universal Serial Bus (USB). One memory card standard that can be followed is that of the Secure Digital (SD) card. The cards can thus be used with different hosts that are compatible with one set of contacts but not the other. A cover that is hinged to the card to normally cover one set of contacts can be rotated out of the way by hand when that set of contacts is being used.
Abstract:
A wireless hearing assist device including a microphone unit and a receiver unit. The microphone unit includes a microphone that receives audio signals, a frequency profile adjustment control circuit that adjusts frequency profile of the received audio signals based on input by a user, and a transmitter that wirelessly transmits the adjusted audio signals. The receiver unit is adapted to be worn by the user and includes a receiver that wirelessly receives the adjusted audio signals transmitted by the transmitter, and a speaker that generates sound based on the adjusted audio signals. In at least one embodiment, the microphone unit includes a Bluetooth enabled RF communication link for wireless communication with an external device other than the receiver unit.
