Abstract: A spine therapy and exercise device (10) for conditioning and exercising the muscles associated with the back, abdomen and legs. The device (10) of the present invention includes a belt member (12) and a harness (14). The harness (14) is carried by the belt member (12) and is provided for receiving the arms of the wearer. The harness (14) of the preferred embodiment is fabricated from a pair of straps (16), each being secured at one end (18) to the belt member (12), crossing each other to form an "X" configuration, and are then being releasably secured to the belt member (12) at their distal ends (20). Adjustment members (26) are provided on each strap (16) for adjusting the size of the harness (14) to the particular wearer by varying the length of the particular strap (16). The belt member (12) includes a torso engagement portion (28), and a leg engagement portion (34) connected in an end-to-end fashion such as to form a continuous loop.

Abstract: A stabilizer for fluid pressure regulators enhancing regulator stability without affecting the regulator capacity. A stabilizer cartridge with a flexible flapper element has three flapper apertures symmetrically located around the flapper outer perimeter. Each aperture is centered within a window of the stabilizer. Means are provided to mount the stabilizer in proper location and orientation of the apertures within the regulator lower casing throat to sense downstream pressure without affecting regulator capacity.

Abstract: A regulator valve having a globe type valve body includes a deformable diaphragm for controlling the fluid flow between the a fluid inlet and a fluid outlet. The deformation of the diaphragm, which is controlled by a pilot pressure introduced into a control chamber within the valve, causes the diaphragm to selectively covers and uncovers a plurality of apertures in a frustoconical baffle to control the flow through the valve. The valve includes a first diaphragm support provided in the control chamber and a second diaphragm support provided on the opposite side of the diaphragm. The second diaphragm support comprises a plurality of concentric cylinders and cross members which form an upper concave surface to correspond to a convex portion of the diaphragm so that the diaphragm is substantially uniformly supported.

Abstract: A rolling diaphragm regulator valve is affixed in a globe type valve body and includes a non-stretchable fabric reinforced liner for covering and uncovering, by rolling action in response to changes in pressure in a control chamber, a plurality of slots in a baffle positioned between the valve body inlet and outlet. An axially movable spring-biased nose cone, mounted behind the diaphragm, provides a surface over which the diaphragm is draped for controlling substantially all movement of the diaphragm. A travel indicator is operable by movement of the nose cone to provide a visual indication of the position of the valve.

Abstract: A rolling diaphragm regulator valve is affixed in a globe type valve body and includes a nonstretchable fabric reinforced elastomer diaphragm for covering and uncovering, by rolling action in response to changes in pressure in a control chamber, a plurality of apertures in a baffle positioned between the valve body inlet and outlet. An axially movable spring-biased nose piece, mounted behind the diaphragm, provides a surface over which the diaphragm is draped for controlling substantially all movement of the diaphragm. A travel indicator is operable by movement of the nose piece to provide a visual indication of the position of the valve. In one embodiment the baffle is notched adjacent to a peripheral mounting surface of the diaphragm, whereat the ends of the fabric reinforcement are exposed to permit entrained gases to escape. Other embodiments include areas of the diaphragm, exposed to the apertures, that have pinholes in the elastomer surface and that have the fabric surface exposed.

Abstract: A spring-suspended mass has top and bottom reflectors. A laser light beam is divided into separate beams that are reflected from the top and bottom reflectors into photo detectors. At the photo detectors, a reference beam from the same laser is recombined with the two reflected beams to produce two interference fringe patterns in response to seismic disturbances of the mass. A count of the number of fringes and fractions thereof that are detected over a unit time interval is proportional to velocity of the mass in terms of the wavelength of the laser beam. The phase difference between the two interference fringe patterns is a measure of polarity of the seismic disturbances.
