Abstract: A junction adapter, having face seal fluid fittings and being for use in a conventional plural line clamping system, has axial extension portions which extend from a central support portion, in a manner which permits face seal fluid connectors to be easily accessed by a wrench or like tool. Two embodiments of this new kind of junction adapter are described. The first embodiment features a junction adapter having axial extension portions which extend symmetrically outwardly from a central support portion substantially beyond the axial extension portions of conventional face seal junction adapters. This first embodiment can be installed in a plural line clamping system in an alternating manner with conventional face seal junction adapters.

Abstract: A one-piece hexagonal junction adapter for use in a conventional plural line clamping system that generally comprises two opposed U-shaped channels having semi-cylindrical collar portions for supporting the junction adapters and stacking nuts which are disposed between the channels and help secure and separate adjacent adapters. The axial thickness of the hexagonal body portion of the junction adapter of the present invention is substantially equal to the width of or distance between the opposed interior side walls of the U-shaped channels. The junction adapter has two retaining shoulder portions, each located between the body and one of the two cylindrical collar support portions that engage the semi-cylindrical collar portions of the channels. These features enable the junction adapter to fit more securely within the plural line clamping system and provide greater resistance to movement due to forces resulting from extremely high fluid line pressures.

Abstract: A retaining block designed to support an undersized fluid line junction adapter to fit within a conventional plural line clamping system used for larger size junction adapters. The clamping system includes two opposed U-shaped clamping units or channels with semi-cylindrical collar support portions that encircle, center and hold cylindrical collars of the larger size junction adapters, and are spaced from one another by substantially stacking nuts. The retaining block includes a central body support portion and two cylindrical collar support portions, one located on each axial side of the central support portion. The retaining block fits within the channels of the plural line clamping system, and its cylindrical collar support portions are sized to physically contact and be secured by those of the channels. The retaining block has a passageway that extends entirely through the block's axial length.

Abstract: A progressive die apparatus and method for cold forming weld adapters. A progressive die apparatus, preferably having at least four working stations and several idle stations, is used to form, weld adapters from rectangular bar stock having a thickness of at least about 3/8 inch. Plain-carbon steel bar stock material or other weldable metal material is successively fed through the progressive die apparatus, which is preferably installed in a knuckle-joint power press.

Abstract: A portable electrohydraulic servo valve analyzer, which has microprocessor-based electronic controller and is operable in a fully automatic mode and a manual mode, is disclosed. The system also includes: a hydraulic manifold block and an adapter block for receiving different servo valve; a servo amplifier and electrical hook-up to the servo valve; pressure gages and hydraulic shut-off valves; a keypad for entering operating input commands and values; two digital displays indicating the current supplied to the valve and the resulting hydraulic flow rate through the valve, and a special turbine flowmeter capable of highly accurate operation of at least three orders of magnitude of flow rates. Most of the system is housed in a single small portable aluminum suitcase. Hydraulic flow is measured by digitally timing the periods between detection of the successive rotating vanes of the turbine, and compensating for nonlinearities in turbine rotation rate at low flows.

Abstract: An electronic flowmeter system including a turbine flowmeter and a digital controller for making highly accurate flow measurements over a wide range of fluid flows and pressures is disclosed. The flowmeter preferably includes a body having a cylindrical bore in which is mounted a turbine having multiple vanes which rotate transversely to the direction of fluid flow. The clearance between the bore and vanes is selected for minimum resistance to fluid flow at extremely low flow rates. Rotation of the turbine vanes is detected by use of a proximity sensor or an optical sensor employing an artificial light and a photodetector. Flow measurements are made by digitally measuring the time periods between successive input pulses generated by detection of the rotating vanes of the turbine. For high temperature or intrinsically safe applications, the optical sensor is used with a fiber optic cable so that the light source and photodetector can be located remotely from the flowmeter.

The flowmeter preferably includes a housing or body having a cylindrical bore in which is mounted a turbine having multiple vanes, and which preferably rotates transversely to the direction of fluid flow. The clearance between the bore and outer edge of the vanes is selected for minimum resistance to extremely low flow rates. Rotation of the turbine vanes is detected by use of a proximity sensor or an optical sensor employing an artificial light source and a photodetector. Fiber optics may be used to locate the light source and photodetector at a location remote from the flowmeter for high temperature or intrinsically safe applications. Flow measurements are made by digitally measuring the time periods between successive input generated by detection of the rotating vanes of the turbine.

Abstract: A junction adapter having a hexagonally-shaped central support portion or body is disclosed for use with a conventional plural line clamping assembly. The hexagonal shape of the adapter body provides many advantages over the rectangularly-shaped bodies of prior art junction adapters. Among the advantages are that such adapters can be easily and very economically made from hexagonal bar stock, using conventional automatic screw machines. The use of the hexagonal bar stock results in a junction adapter formed of one piece of metal and thus provides an adapter that does not have any connection joint that can break away. The hexagonal adapter can be oriented in any position and even be slightly misaligned while still being secured firmly within a plural line clamping assembly.Three embodiments of the hexagonally-shaped adapter are disclosed, and each includes a hexagonally-shaped body, two co-axial connection members, and an axially arranged fluid passages through the junction adapter.
