摘要:
An improved baby changing station which is utilized primarily to change the diapers of a baby or young child. The design includes an upper changing area with specially shaped protective ridges. The design further includes a lower supporting portion which is divided into at least three distinct areas. A first area is utilized for undersink storage. A second lower area includes multiple drawers for storage of sundry items. A third lower area contains stairs or steps for a toddler to use as needed. The design provides a safe floor-mounted and efficient changing station as compared to the fold-down wall mounted units currently in widespread use.

A method of freeze drying sucralose includes contacting a sucralose solution with a cold surface or a cold fluid to freeze the solution, and evaporating the solvent to dry the sucralose. The sucralose solution may include undissolved crystalline sucralose. Non-agglomerated sucralose spheres may be produced in some aspects of the invention.
摘要:
A battery load leveling system for an electrically powered system in which a battery is subject to intermittent high current loading, the system including a first battery, a second battery, and a load coupled to the batteries. The system includes a passive storage device, a unidirectional conducting apparatus coupled in series electrical circuit with the passive storage device and poled to conduct current from the passive storage device to the load, the series electrical circuit coupled in parallel with the battery such that the passive storage device provides current to the load when the battery terminal voltage is less than voltage on the passive storage device, and a battery switching circuit that connects the first and second batteries in either a lower voltage parallel arrangement or a higher voltage series arrangement.

A plastic pipe support assembly includes a pair of snap-on wall brackets or fittings with each bracket or fitting including a base portion and a snap-on, pipe receiving portion. The base portion includes holes for receiving nails or screws for mounting to studs in a building, for example; and the snap-on pipe receiving portion includes a pair of jaws for extending around a support pipe, with the opening between the jaws having a spacing which is less than the diameter of the support pipe so that the support pipe may be snapped into the jaws, and held firmly in place. One or more pipe-to-pipe fittings may be provided with each fitting having a pair of pipe receiving jaws, for mounting water pipes to the support pipe. The support pipe and the brackets or fittings may be all formed of the same type of plastic as the water pipe, such as polyvinyl chloride, or chlorinated polyvinyl chloride. Plastic solvent may be employed to bond the pipes and fittings together.

Plastic liner sections define a drainage channel when placed end to end. Each end has a stiff, double walled flange at each side of the end adapted to butt up to a similar flange at the adjacent end of the next sections. The double walled construction of the flanges stiffens the ends significantly reducing the risk of deformation by the hydrostatic forces produced by wet concrete during installation. A groove is formed inwardly of the flanges on a female end of the liner section and receives a sealing ring, which is held in place by a lip formed on a male end.
摘要:
A method of deploying cable in a body of water comprising an autonomous underwater vehicle (AUV) capable of converting vertical motion into horizontal travel, and placing cable in the body of water with the AUV. The cable, usually a cable sensor array, is released from a cable storage section of the AUV as the AUV glides horizontally. Vertical motion can be provided by buoyancy change, by dropping the AUV into the water, or by release of the AUV from a weighted bunker at the bottom.
摘要:
A keyboard support mechanism containing a novel articulating arm mechanism for permitting vertical movement of the keyboard shelf. The articulating arm mechanism has six major components: (1) a mounting bracket, (2) a mounting bracket support in combination with a swivel bracket, (3) a shelf bracket, (4) an upper arm, (5) at least one side arm, and (6) at least one stopping means. The upper arm links the shelf bracket and the mounting bracket; the side arm and the stopping means cooperate to keep the shelf bracket (and hence the keyboard shelf) at a constant angle relative to the ground.

A system (10) for transmitting a synchronous stream of data is set forth. The system (10) includes a universal asynchronous transmitter/receiver (30) includes a circuit for asynchronously transmitting a data character; a timing circuit for generating a signal (255, 260) upon completion of the asynchronous transmission of the data character; and an output line (140, 145) controllable to go to a data state independent of the data states of the bits of the data character. The system further includes a central processing circuit (15, 20, 25) that is responsive to the timing circuit of the UART (30). The central processing circuit (15, 20, 25) controls the output line (140, 145) of the UART (30) to go to a series of data states corresponding to individual bits of the synchronous data stream. The period of the individual bits corresponds to the signal generated by the timing circuit.
摘要:
A pipe repair coupling comprising a pair of semi-circular separate and independent coupling segments. Each segment is identical in cross section, length, and width. When coupled together along one elongated edge in a snap fit relationship, the interconnected segments may be placed about a cylindrical pipe to repair a hole or the like therein, then squeezed together to lock along the other free elongated edges thereof. A suitable adhesive is applied between the coupling and the pipe being repaired prior to squeezing the segments together.
