Title: Sealed load cell construction

Granted: 1982-06-29
Abstract: ABSTRACT OF THE DISCLOSURE           A load measuring device is provided herein which operates with a small amount of vertical travel.  The load measuring device includes a base with a thin reservoir for load-transmitting material in the form of a non-compressible fluid (e.g., oil)       forming the lower portion of the base.  A flexible diaphragm is provided which is in direct contact with the load-transmitting material in the reservoir.  A platform is provided for applying a load to the diaphragm.  Finally, a transducer including an integral diaphragm at its base is held with such integral diaphragm in direct contact with the flexible diaphragm to provide a reading which is proportional to the absolute value of the load.  The invention thus provides a sealed, shockproof load cell whose manufacture is greatly simplified and whose cost is reduced both in terms of time and material.  Moreover, its installation in a weigh scale is much simplified since there is no hydraulic connection needed between the load cell and the transducer.

Abstract: ABSTRACT         In an injection-metallurgical process performed in a ladle, lime is injected during a first phase after the deoxidation, removing the main part of the sulphur existing in the melt. During a second phase thereafter calcium-silicon, calcium-carbide or calcium-cyanamide is injected, which has a desived impact upon the morphology of the remaining inclusions. At the same time the flowability of the steel is improved, which is particularly important in the production of deep-drawing steels.

Abstract: ABSTRACT OF THE DISCLOSURE         A heating control apparatus includes a vapor sensor for detecting the vapor liberated from the food to be cooked and a microcomputer for controlling the heating sequence in response to a signal from the vapor sensor for automatic heating control suitable for the food is disclosed.  The time T1 from the heating start to the detection by the vapor sensor of the vapor liberated from the food is counted by the microcomputer.  A constant K determined according to the type of food which is determined by cooking tests in advance and which is stored in the microcomputer is selected in connection with the time T1.  The time T1 is multiplied by the selected constant K to determine the time T2 from the detection of vapor by the vapor sensor to the end of cooking by heating.  The food heating sequence is controlled by the microcomputer, especially, utilizing the facts that the time T1 is proportional to the volume of the food of the same type and that the constant K is not fixed for the same food but varies with the volume thereof.

Abstract: 22,356 Abstract of the Disclosure A floor panel for a raised floor system includes a substantially flat rectangular top plate and a rectangular formed bottom member.  The bottom member includes three groups of box beams and a number of support regions. Members of the first group of box beams run parallel to and in close proximity to each edge of the bottom member and intersect each other near the corners of the bottom member.  Second and third groups of box beams run at an angle to each other across the bottom member at an angle of 45 degrees with the edges of the bottom member and intersect each other and the first group of box beams. The box beams are operative to transmit applied stress to the corners of the floor panel.  Support regions are relatively uniformly distributed over the area of the floor panel.  A preferred method of fastening the bottom member to the top plate includes coating the support regions of the bottom member with a heat curable struc-tural adhesive, spotwelding the two pieces together at several points, and heating the assembly until the structural adhesive is cured.

Abstract: ABSTRACT     A valve assembly has a tapered valve body disposed within a tapered bore in a housing with a rotatable tapered valve member in a tapered bore in the valve body to control flow of a radioactive slurry through the housing.  The valve body has a sealing liner on its outer wall sealing between the valve body and the housing and a sealing liner on its inner wall sealing between the valve body and the rotatable valve member.  In one embodiment, the sealing liners are integral and mounted to the valve body.  The valve body has a rib arrangement on its inner wall acting through the sealing liner to form pressure sealing areas with the rotatable valve member.  The spaces between ribs form pressure relief areas.  The rotatable valve member is rotated through rotation means by a remote actuator.  The rotation means is disposed within an extension connected to the valve body.  The extension means of the valve body is disposed within an extension secured to the housing.  When the valve unit is to be replaced, a positive air flow is produced from an access opening to the actuator by a suction pump.

Abstract: ABSTRACT OF THE DISCLOSURE         When heavy duty electric pumps as those used in muni-cipal water mains and sewage systems are operating, they are working against the static pressure of the lines already full of liquid and usually flowing upgrade from the pumping station for a long distance, to water storage tower or point of dis-charge.  This mass of water flowing away from the pump of course has momentum.  The outlet of the pump into the main is through a heavy duty check valve to prevent back flow of water from the pipe into the pump.  When there is a breakdown of a pump or motor, or less power to the pump when it is work-ing, the sudden drop in pressure in the main with the volume of water in the main still in motion, a shock wave is set up in the pipe line that travels with the speed of sound toward the discharge point or first high point in the line, and it reverses with amplified force back to the pumping station which will open the line to a drain to relieve the force of the returning shock wave.  If this valve opens immediately upon stoppage of the pump vast amounts of water will be spill-ed from the system, perhaps with no provision for its adequate disposal.  The present invention introduces a time delay relay system at the pumping station that delays the opening of the surge valve for a preset period of time but in advance of the return shock wave that will spill enough water from the main before the shock wave returns to break the force of the returning shock wave to dissipate harmlessly.
