Patent BR-8303020-A (BR)
Inventor: CHAUDOT GERARD
IPC: E21B43/36
Filed: 1983-06-07
Abstract: A system according to the invention includes a working well head 1 whose producing head is connected by a rigid or flexible pipe to at least one underwater degasifier tank. A pump 4 for lifting the product from the well or wells 1 is regulated by a control valve which responds to the discharge flow of liquids and/or variations in weight and/or buoyancy of the degasifier tank 3. A valve for regulating the flow of product from the well 1 is controlled by a second control means. The second control means may modulate the gas sealing pressure by pinching a stream of gas at some point in the piping in response to the relative buoyancy of said underwater degasification tank. Combinations of the various systems disclosed in the invention make it possible to increase the recovery of desired product fluids from an underwater deposit.

Abstract: A sheet of metal of given thickness is press-formed to provide a part having a substantially constant thickness on a double action press. The sheet to be formed is disposed on a support. A first outer slide, or blank holder is applied on the peripheral portion of the sheet. A second central slide is applied on the central portion of the sheet. The peripheral portion of the sheet is formed while allowing it to slide under the blank holder, by displacing relative to said support at least one active part of the outer slide so as to compensate, in certain regions of the finished part, for excess areas of the sheet, for the given thickness of said sheet, relative to the volume of metal to be formed, and displacing simultaneously with the displacement of the part the central slide so as to shape angular volumes of the central portion of the sheet by application of the sheet against the surfaces of the central part of the support.

Abstract: A hydrous oxide sol such as a zirconia sol is applied to a solid e.g. metal surface and there cured to form a protective coating. The sol may include an adhesion promoter such as a silane and/or a sub-micron passenger powder. Application to the surface may be in one step, or two steps with the second designed to gel the sol. Depending on the microtexture of the sol and the surface, the treatment can be used to control, by increasing or decreasing, the adhesive properties of the surface to a subsequently applied organic coating, or simply to improve corrosion resistance.

Abstract: A method and a device for measuring the heart function are described. In this method, the pressure and the volume of the left ventricle are measured. From these values, the product is formed as a function of time. From this product, the time derivation is determined, and the time derivation is used to define the gradient characterising the cardiac output index. In order to measure the pressure of the left ventricle, the arrival times of the cardiac pressure pulses at a predetermined site are measured at a multiplicity of pressure values, in particular a series of optimised pressure values. <IMAGE>

Abstract: With this safety brake device, overspeeds of an elevator cabin or of a counterweight in the down direction are avoided. On its front side, a housing (1) has a recess (2) which extends over the entire housing height and on one end of which a brake plate (3) is arranged which has a free leg (4) plunging next to it. A trapezoidal stirrup (6) with a rectangular extension (7) projecting from the housing (1) is inserted into the part of the recess (2) adjoining the leg (4). On the guide-rail side, the stirrup (6) has a slotted link (9) running up at an angle and having a U-shaped cross-section. The two end faces of the slotted link (9) serve as rolling paths for roller spindles (12) arranged on a cylindrical catch roller (11). A camber in the form of an additional inclined control face (13) is provided in the lower part of the slotted link (9), with which camber the catch roller (11) is guided more quickly to the free leg (4). The recess (2) ends with an inclined wedge surface (14) on the side opposite the brake plate (3). The stirrup (6) bears on the inclined wedge surface (14). A longitudinal slot (15) running vertically through the stirrup (6) and deep into the extension (7) gives the stirrup (6) the necessary elasticity.

Date Nov. 14, 1991.An electrical screw-on terminal assembly is provided for a connection to wires or cables, particularly those with eye connectors. The terminal assembly has a housing and a screw which, as it is screwed in, passes through a first plate, and when fully screwed in, a second plate. The first plate is mounted so that it cannot rotate or be moved longitudinally, while the second plate is mounted so that it can be moved longitudinally but not rotated. When the terminal is completely open, the second plate abuts a stop on the housing and is held in this position by a resistive force, which can be overcome by the screw, so that the aperture onto which the cable or cable eye is inserted remains unobstructed. The screw can be screwed into a bore in the first plate until it engages the second plate. The bore in the first plate has no internal thread, but has projections which engage the screw threads.

Abstract: A pharmaceutical dosage form comprises, in one portion thereof, a substantially single (+)-enantiomer of a chiral drug other than verapamil and, in another, separate portion thereof, a substantially single (-)-enantiomer of the drug wherein, in use, the different enantiomers are released at different rates from the dosage form. The dosage form is useful for administration of chiral drugs where both enantiomers have a valid pharmacological input, and where a clinical benefit may be realised by controlling the release rates of those enantiomers. Examples of such drugs include, in particular, tramadol and warfarin.
