Differential pressure instrument support manifold having rotary mode selection system

A spool type differential pressure transmitter support and valving manifold having a manifold body defining a process face and a transmitter face and having a generally cylindrical internal surface defining an open ended spool chamber and having signal inlet and outlet passages intersecting the process and transmitter faces and being in communication with the spool chamber. The manifold body also defines a vent passage which is in communication with said spool chamber. A spool member is positioned for rotation to "run", "zero" and "off" positions within the spool chamber, has ends extending from the open ends of the spool chamber and has a pair of transversely oriented body passages positioned for selective registry with the signal inlet and outlet passages at the "run" position of the spool member. Circumferential seals each preferably comprising an O-ring and a back-up ring establish sealing between the spool member and the manifold body and serve to isolate the signal passages from one another and to prevent leakage of signal pressure at the open ends of the spool chamber. A plurality of mode seal elements are carried by the outer periphery of the spool member and provide for manifold mode selection to the "run", "zero" and "off" positions responsive to rotational positioning of said spool member relative to said manifold body to permit calibration of the differential pressure transmitter with the pressurized process in operation.

Defoaming method and device for eliminating foam of drilling fluid by thermal radiation

The invention relates to a defoaming method and a deforming device for removing the foam of drilling fluid through thermal radiation, which belong to the technical field of the physical defoaming of the drilling fluid. The defoaming device comprises a cylindrical container. The defoaming device is characterized in that a gas outlet is arranged on the top of the cylindrical container, a fluid and slag outlet is arranged on the bottom of the cylindrical container, a foam inlet is arranged on the side face of the middle lower part of the cylindrical container, a thermal radiation element is arranged on the upper inner wall of the cylindrical container, a temperature sensor is arranged below the thermal radiation element on the cylindrical container, an ultrasonic foam height sensor is also arranged below the thermal radiation element on the cylindrical container, and fluid level sensors are arranged on the middle and lower parts of the inside cylindrical container. The foam flows into the device through the foam inlet, the thermal radiation element on the device gives off thermal radiation to break the foam with low intensity near the device, the separated gas is discharged through the gas outlet, and the foam base fluid and the solid carried by the foam are discharged through the fluid and slag outlet. The defoaming device can quickly remove a great amount of foam discharged from foam drilling and prevent the foam from being accumulated in a mine. In addition, the nature of the foam base fluid is not affected, thereby facilitating the cyclic utilization of the foam base fluid.

Ohmic defroster for foods and process

The defrosting apparatus of the present invention uses ohmic heating as operating principle, circulating an electric current through blocks of food. In the particular case of foods, electric current conduction capacity is low, which means that energy is dissipated into the material in the form of heat, thereby heating same. In this case, the block of frozen food acts as a resistor in the electrical circuit which opposes the passage of the current. The defrosting apparatus of the present invention generally comprises a plurality of compartments for receiving blocks of frozen food and for connecting said blocks to an electrical circuit by means of electrodes. In addition, the apparatus includes a plurality of heating modules, a module for controlling and monitoring variables, a plurality of power modules for supplying the necessary electrical energy, and a plurality of pneumatic modules for guaranteeing contact between the blocks of food and the electrodes of the power system. The heating modules are designed to receive the frozen blocks of food and to supply the electrical energy necessary to heat the material and to obtain the required temperature. The defrosting apparatus comprises a plurality of heating modules, depending on the capacity required and on the geometry of the blocks of food to be defrosted, and the number of modules may be between four and eight, but is not limited thereto. The module for controlling and monitoring variables is designed to record the behaviour of the variables that play a role in the defrosting process and the operation of the equipment. The equipment includes a single system that governs the entire operation thereof. The defrosting process for blocks of frozen foods is characterized by (i) placing the block of frozen food in a plurality of compartments, (ii) connecting said block to an electrical circuit by means of electrodes, (iii) guaranteeing contact between the frozen block of food and the electrodes, and (iv) circulating an electric current through the block of frozen food. Said electric current is that which is necessary to heat the frozen block of food and to obtain the necessary temperature.
