Abstract: Described are solid dose nanoparticulate naproxen formulations having high rates of dissolution. The solid dose nanoparticulate naproxen formulations can comprise an alkali compound, which functions to increase the dissolution rate of the naproxen following administration. Alternatively, the solid dose nanoparticulate naproxen formulation can comprise an alkali compound and an acidic compound, which can react together to form carbon dioxide. The formed carbon dioxide can also aid in increasing the dissolution rate of the naproxen following administration. Also described are solid dose nanoparticulate naproxen formulations having decreased concentration of a binder/disintegrant agent. Such compositions also provide an increased rate of dissolution of naproxen following administration.

Abstract: An apparatus and method for detecting twist in an articles such as pieces of lumber being carried on a high-speed longitudinally moving conveyer use a non-contact scanning technique according to which a pair of transverse scan line beams is directed onto a surface of the article in spaced relationship in the conveying direction, and successive scans of corresponding simultaneously scanned pairs of spaced transverse areas on the article are repeatedly performed while the article is conveyed, to generate profile data characterizing position of each transverse area in a reference system. The profile data characterizing the respective position of both transverse areas is compared with one another to generate partial twist indicative data associated with each scan, followed by a summation of the partial twist indicative data associated with all scans to obtain an indication of the twist in the considered portion of the article. The proposed apparatus and method provide accurate twist measurement even if the article is subjected to some wobbling movement relative to the conveying surface.

Title: Speed control for a utility vehicle
Inventor: BURGART JOSEPH GERARD
IPC: F16H59/44
Filed: 2002-07-09
Granted: 2008-01-15
Abstract: A cruise control system for a utility vehicle, which is speed-controlled by a hydrostatic transmission, includes a controller having an input for receiving a selectable set speed signal, and an output for sending a speed control signal to at least one proportional valve of a hydrostatic transmission servo control system.  The vehicle ground speed is continuously monitored by a speed sensor operatively associated with a rotating gear in the vehicle drive train that rotates in proportion to vehicle ground speed, to create a ground speed signal. The selectable set speed signal can be input to controller memory by driving the vehicle at a desired ground speed and then activating a speed set switch. The speed control algorithm of the controller thereafter compares the set speed to the ground speed signal from the speed sensor and corrects the control signal to the proportional valve to correct hydrostatic transmission speed output.

Abstract: A support device for use within a fastener driving tool is fixedly attached to the tool s workpiece contact element so as to be movable therewith between extended and retracted positions. When the workpiece contact element, and the support device mounted thereon, are moved to the retracted position, a pocket or recessed portion of the support device will envelop a tip portion of a second uppermost fastener disposed within the tool magazine, while the first uppermost fastener is disposed within. the tool drive bore, such that the second uppermost fastener, as well as the remaining fasteners within the magazine, is properly supported and stabilized such that shock and vibrational forces, attendant the driving of the first uppermost fastener, are effectively prevented from being transmitted to the second uppermost and remaining fasteners. In addition, the pocket or recessed portion serves to partially close the magazine opening through which the fasteners are serially advanced such that the first uppermost fastener will be maintained coaxially aligned within the tool drive bore, and an upstream leading edge of the pocket or recessed portion also defines a shearing edge for properly shearing those portions of the collation strip which interconnect adjacent pairs of the fasteners within the collated strip of fasteners.

Title: Mercury free discharge lamp with zinc iodide
Inventor: LAPATOVICH WALTER P
IPC: H01J9/395
Filed: 2002-12-20
Granted: 2010-12-14
Abstract: A compact fused silica, electroded HID lamp for automotive forward lighting, which contains no mercury. The lamps voltage, approximately 40 volts, is developed in this lamp by vaporizing zinc iodide instead of mercury. A compromise between voltage and luminous flux is achieved through the choice of the sodium scandium (Na:Sc) molar ratio, between 4.5:1 and 6:1 and a zinc iodide (ZnI2) dose of 2 to 6 micrograms per cubic millimeter that permits the lamp to operate within the North America, European and Japanese automotive color specifications for white light. The voltage in the lamp can be controlled according to the zinc iodide doping level without seriously impacting the visible spectrum otherwise provided by the other known dopants in the lamp.
