Abstract: A dump truck end gate locking system includes a dump truck having a chassis and a cargo box which pivots between a transport position and a dumping position. The cargo box has an end gate. A sensor is provided for sensing when the cargo box is in the transport position. A locking member is provided having a locked position engaging the end gate and an unlocked position disengaged from the end gate. A drive mechanism for the locking member is coupled to the sensor. The drive mechanism moves the locking member to the locked position to secure the end gate when the sensor indicates the cargo box is in the transport position. The drive mechanism moves the locking member to the unlocked position to release the end gate when the sensor indicates the cargo box has moved from the transport position to assume a dumping position.

Abstract: The invention provides a novel class of vitamin D related compounds, namely, the 2-alkylidene-19-nor-vitamin D derivatives, as well as a general method for their chemical synthesis.      The compounds have the formula (I) where Y1 and Y2, which may be the same or different, are each selected from the group consisting of hydrogen and a hydroxy-protecting group, R6 and R8, which may be the same or different, are each selected from hydrogen, alkyl, hydroxyalkyl and fluoroalkyl, or when taken together represent the group -(CH2)x- where x is an integer from 2 to 5, and where the group R represents any of the typical side chains known for vitamin D type compounds. These 2-substituted compounds are characterized by low intestinal calcium transport activity and high bone calcium mobilization activity resulting in novel therapeutic agents for the treatment of diseases where bone formation is desired, particularly low bone turnover osteoporosis. These compounds also exhibit pronounced activity in arresting the proliferation of undifferentiated cells and inducing their differentiation to the monocyte thus evidencing use as anti-cancer agents and for the treatment of diseases such as psoriasis.

Abstract: The invention relates to a switching device for switching input data frames (IDF) from a plurality of N input lines (i1, i2, ... i n, i N) to output data frames (ODF) on a plurality of M output lines (o1, o2, ... o n, o M). The switching device contains a number K of switch pattern units, each containing a specific switch pattern. A number K of frame store memories (FSM j) each store all input data frames from all input lines in every frame period. Each frame store memory is used for selecting bits to a sub-group of M/K output lines. The parallelly working units (u1, u2, ... u K) each sequentially select a plurality of M/K bits from the stored input lines. The parallelly working units (u1, u2, ... u K) each sequentially select a plurality of M/K bits from the stored input data frames and simultaneously assign the selected bits to the output data frames on the respective sub-group of output lines. The selection and assigning of bits in each unit is performed at a M/K times higher clock rate than the bit rate on the input data lines. Thus, a bit-orientated reading of input data frames and writing of output data frames is achieved which allows a flexible switching of full rate as well as sub-rate input PCM data frames.

Abstract: A rolling massage device continuous motion reciprocal drive structure comprised of a long drive shall, the two end of which arc pivotably installed in a base plate that is also inserted through the center section of a sleeve hole at the lower extent of a bottom mount, and a massage device sleeved over the center section of the drive shaft. The center section of the drive shaft consists of a clockwise spiral slide tracking groove and a counter-clockwise spiral slide tracking groove in a crisscross arrangement and, furthermore, completes a two-ended cycling crossed bi-directional screw rod. The upper extent of the center section area of the bottom mount sleeve hole provides for the implantation and sleeving in of a cylindrical active link block having a double hyphen- profiled guide plate extending from its lower end that is inserted into the slide tracking grooves.  As such, while the drive shaft is being rotationally driven in a set direction, since the guide plate in the groove is forced to follow in the direction defined by the interior section of the track path, the bottom mount equipped with massage components at its top surface is carried into continuous motion in an axial direction and, furthermore, achieves continuously driven reciprocal travel following the crisscross configuration of the clockwise slide tracking groove and the counter-clockwise slide tracking groove on the crossed bi-directional screw rod, which is among the innovative features of the present invention.

Abstract: A light delivery system includes a light source. A first generally tubular, hollow coupling device with an interior light-reflective surface receives light from the source at an inlet and transmits it to an outlet. The coupling device increases in cross sectional area from inlet to outlet in such manner as to reduce the angle of light reflected from the surface as it passes through the device. A thermal-isolating region has an inlet positioned in proximity to an outlet of the coupling device and has an outlet for passing light to an optical member, the thermal-isolating region comprising one or more members. A waterproof container for the light source and coupling device has an aperture allowing light to pass out of the container. The aperture is sealed in part by a portion of a member of the thermal-isolating region. Advantageously, the system can be buried beneath the surface of the ground.  This avoids the problem of people or equipment colliding with the system. The components in the sealed container are protected from intrusion by wildlife or deterioration from dirt and dust. In some embodiments, the container may be free of a fan, reducing the complexity and noise of the system.
