Abstract: The device is capable of measuring tension in a cable subjected to torsion and longitudinal deformation upon tensioning thereof. This device comprises a training connection and a packing ring adhered to the cable at respective first and second, longitudinally spaced apart locations thereof. A roller cap is mounted on the packing ring through single row radial bearings whereby the cable is free to rotate, along with the packing ring, in the roller cap about the longitudinal axis of the cable. A vibrating wire strain gauge has a first end microwelded to the training connection and a second end microwelded to the roller cap, whereby longitudinal deformation of the cable is transmitted to and measured by this gauge. A flat key is inserted in respective longitudinal grooves of the training connection and roller cap to maintain, about the longitudinal axis of the cable, a constant relative angular position between the training connection and the roller cap whereby, upon torsion of the cable, the cable rotates with the packing ring in the roller cap to prevent torsion of the cable to affect the vibrating wire strain gauge and influence the longitudinal deformation measurement.

Abstract: A refrigerant compressor includes a compressor housing defining a chamber in which successive strokes of intake, compression, and discharge of a refrigerant gas are repeatedly performed. The chamber is divided into a compression chamber and a discharge chamber by a valve plate. A discharge hole links the compression chamber to the discharge chamber. The valve plate includes an end surface which faces the discharge chamber. A discharge valve regulates a flow of the refrigerant gas from the compression chamber to the discharge chamber. A valve retainer limits the bending movement of the discharge valve in the direction in which the refrigerant gas exits the discharge hole. The valve retainer is secured to an axial end surface of the valve plate together with the discharge valve by a fixing bolt. The discharge valve bends as it opens and closes the discharge hole. The valve plate includes an annular groove formed at the end surface thereof. The annular groove surrounds the discharge hole and is entirely overlaid by the discharge valve. Also, an air gap may be formed between the discharge valve and the valve plate. Thereby, noise due to resonant vibration caused by the discharge valve can be effectively reduced or eliminated.

Abstract: A  gravity  conveyor  system  is  disclosed including means for actively stopping the rotation of the conveyor rollers  following disengagement with a conveyed  article  after  it  passes  thereover  and  in advance of a next succeeding article.  This allows each article to accelerate an engaged roller from a rest position so that precise transport control is effected without the use of positive drive mechanisms.  Accurate control for throughput and accumulation results from cooperation between brake assemblies associated with each conveyor roller, a sensor assembly and a pneumatic control assembly, each combination of which acts in an operational  zone.   The  rotation  of  the rollers  is preferably stopped as a function of the sensed position of articles along the system.  The pneumatic control assembly further includes a logic control mechanism that operates  to  selectively  control  the  application  of braking action either momentarily to allow continued controlled throughput or for a prolonged period of time to allow controlled accumulation.  The gravity control system acts to practice a method for controlling the transport of articles without positive drive assistance in reliance on stopping the rotation of the rollers after an article has passed thereover and in advance of a next succeeding article.  The apparatus and method further provide a means for stopping articles at the discharge point of the conveyor system without the need for extraneous stop mechanisms.

In the case of a capacitive sensor, the electrodes have a high insulation resistance relative to each other, the diaphragm exhibits only little tensile strain in the finished condition, no sublimation step is necessary to prevent the diaphragm from sticking to the substrate, the diaphragm provides a measurement signal over a wide pressure range even if its rests against the substrate, the measurement signal is virtually temperature-independent, and only few chemical-vapor-deposition and photolithographic steps are necessary. The capacitive sensor has a glass substrate and a diaphragm which bound a hermetically sealed cavity, the substrate supporting, on the cavity side, a substrate electrode with first interconnection tracks or corner pads extending therefrom, the diaphragm being made of the material of a first insulating layer, which firmly adheres, at least in part, to the substrate at the edge of the cavity, and supporting, on the side remote from the cavity, a top electrode and a second insulating layer which completely covers the top electrode and the diaphragm and hermetically seals the cavity, and the top electrode having second interconnection tracks extending therefrom onto the first insulating layer outside the diaphragm. In the case of a resistive sensor, the substrate electrode is omitted, and the top electrode is replaced by a half or full bridge consisting of piezoresistors. Four manufacturing process variants are disclosed.

Title: Intrinsically safe power source
Inventor: HUCZKO KEVIN M
IPC: H02H9/00
Filed: 1995-04-07
Granted: 2005-02-08
Abstract: An intrinsically safe power supply unit is provided for conditioning power supplied by a power source. An input power converter connected to the power source receives current from the power source. A direct output crowbar and discrete impedance elements dissipate and limit the energy in the power supply unit that would otherwise be delivered to an external fault. In addition, the direct output crowbar extracts energy from any external storage elements. An adaptive shutdown circuit distinguishes nominal load conditions, including load changes from an external fault. A multistage LC power filter is used to minimize the stored energy that would be deliverable to an external fault or dissipated by the direct output crowbar and discrete impedance elements, The combination of the direct output crowbar, discrete impedance elements, adaptive shutdown detection circuitry and multistage LC power filter significantly improves the level and quality of intrinsically safe power delivered by the power supply unit.
