Abstract: Embodiments of the disclosure relate to a method of preparing a bundled cable. In the method, a plurality of subunits is wound around a central member in one or more layers of subunits to form the bundled cable. For a section of the central member, each layer of subunits has a pitch over which a subunit of the layer of subunits makes one revolution around the section of the central member and a length of the subunit required to make the one revolution. The subunits are configured to have a nominal helical length equal to the ratio of a nominal length to a nominal pitch. Further, in the method, a measurement of the bundled cable is monitored, and a winding rate of the plurality of subunits is adjusted based on the measurement in order to account for deviations from the nominal helical length.

Abstract: An intermediate power supply unit for distributing lower voltage power to remote devices is disclosed. The intermediate power supply unit includes a higher voltage power input configured to receive power distributed by a power source and a power coupling circuit configured to couple the higher voltage power input to a plurality of power coupling outputs. If it is determined that a wire coupling the power source to the higher voltage power input is touched, the higher voltage power input is decoupled from the power coupling outputs. The intermediate power supply unit also includes a power converter circuit configured to convert voltage on higher voltage inputs to a lower voltage applied to one or more lower voltage outputs. The power converter circuit is also configured to distribute power from the one or more lower voltage outputs over a power conductor coupled to an assigned remote device.

Abstract: A high purity valve (10) includes a valve body (12) having an inlet (40) and an outlet (42) separated by a valve seat (32), and a diaphragm (22) having a central stem (23) that has a first end coupled to a piston (20) for actuating the valve, and a poppet (28) for engaging the valve seat to close the valve. The poppet forms a dual point seal (50/52, 50?/52?) with the valve seat having at least two points of contact between an annular surface (30) of the poppet and the valve seat. The annular surface of the poppet may be either a concave surface or a convex surface that provides the dual point seal. The valve has a retainer (14) adjacent the diaphragm, and the diaphragm has a flexible web (26) that extends radially outward from the central stem. The retainer has a surface (60) adjacent the web, and the surface is spaced apart from the web such that the web does not contact the surface when the valve is pressurized.
