An alternating pressure pad includes a first series and a second series of inflatable cells. The first and second series of inflatable cells are interleaved, with one series within the other series. Each cell of the first series of inflatable cells and each cell of the second series of inflatable cells extends transversely across the alternating pressure pad and defines a non-linear and non-repeating path, with the path defined by substantially all of the cells of the first series being identica...

Alternating Cymbals utilize two pairs or sets of cymbals, a first pair and a second pair of cymbals, which play alternately with a single actuation usually by a foot pedal. Both sets of cymbals are supported by a support means which includes a tripod, column with a bracket extending from the column. The first pair of cymbals are mounted at the upper end of the column. A shaft in the column pulls the top cymbal of the first pair of cymbals down against the bottom cymbal of the first pair of cymba...

An automatic, hydraulically actuated, sequencing valve for use with a pair of hydraulic acutators (e.g. double acting hydraulic cylinders) includes a valve body having a cylindrical bore therein. Cam members at either end of the bore are engaged by pins on the ends of a cylindrical spool, thereby rotating the spool 30.degree. each time it engages one of the cam members. A third cam member incorporated into the spool alternately locks open one of a pair of check valves as said spool is pressure s...

An alternating pressure pad including at least two sets of inflatable cells, each set being alternately inflated and deflated, wherein at least one cell in each cell set has for example, circumferential internal membranes or external straps, to accelerate the deflation of the at least one cell.

The present invention is directed to an alternating pressure pad comprising at least two sets of inflatable cells, each set being alternately inflated and deflated, wherein at least one cell in each cell set has further means, such as, for example, circumferential internal membranes or external straps, to accelerate the deflation of the at least one cell.

The AC detection coil is a toroidal coil and includes plural radial-line conductors which are formed on a front face and a rear face of a substrate, conductive connection parts and conductive through-holes which connect electrically each end of radial-line conductors, wherein plural winding turns are consecutively formed by a connection of each radial-line conductor on the front and the rear faces, respectively, and include a forward coil and a backward coil, and each shape on the front and the ...

An imaging system for inspection of a sample includes an illumination module, which irradiates a surface of the sample with pulsed optical radiation. A mechanical scanner translates at least one of the sample and part of the imaging system so as to scan an area irradiated by the pulsed optical radiation over the surface in order to irradiate successive, partially overlapping frames on the surface by respective successive pulses of the pulsed radiation. A collection module collects the optical ra...

The present invention relates to an alternating seam for joining two pieces of stretchable fabric. The alternating seam can be used for making garments, such as pant garments. The alternating seam has a non-inverted seam that extends from a seam inversion point to a desired length below the seam inversion point. Outer sides of the two fabric pieces are in opposing contact with each other along the non-inverted seam. The alternating seam also includes an inverted seam that extends upwardly from t...

Apparatus is described for converting alternating current at line frequency (50 or 60 Hz) into alternating current of much higher frequency and at a voltage suitable for operating loads such as lamps which draw high starting currents. The apparatus has a current feedback inverter oscillator which may be implemented by switching transistors connected in push-pull relationship through output and feedback transformers which have windings connected in series with the load. The load current is fed ba...

An alternating current generator has a cooling function for a vehicle and includes a front bracket and a rear bracket with annular recessed portions that form a peripheral cooling chamber. A cooling cover is provided on the rear bracket. The cooling cover and the rear bracket form a rear cooling chamber. The peripheral cooling chamber and the rear cooling chamber are connected together through a connecting hole provided in the rear bracket. The front and rear brackets also form a parts housing c...
