Patent EP-0386373-A2 (EP)
Inventor: TAI WEN-TONG
IPC: F16L15/04
Filed: 1989-11-20
Abstract: An oil field tubular connection is provided for joining metallic tubulars at a well site. At least one end of each tubular is provided with a frustoconical external sealing surface for metal-to-metal sealing engagement with a corresponding surface of an adjoining tubular. A plurality of antigalling grooves provided along the external sealing surface each project radially inward thereof and circumferentially encircle the threaded end of the tubular member and seal the groove from fluid communication with the interior of the tubular member. The antigalling grooves are particularly well suited for use with a low angular taper sealing surface of less than approximately 7°, and reduce galling between the metal sealing surfaces during makeup of the connection. Each tubular connection may also include an energizing groove spaced axially between the exterior sealing surface and the threads on the tubular member. The energizing groove receives excess thread lubricant, and has a uniform radial depth circumferentially about the tubular member for reducing the cross-sectional thickness of the tubular member, thereby allowing the exterior sealing surface to move radially outward in response to increased tubing pressure and allowing more flexibility for increased interference between the sealing surfaces during makeup of the connection.

Title: Use of a stereo control
Inventor: KELLER EDWIN
IPC: H01C10/20
Filed: 1990-03-23
Abstract: The stereo control is used for changing simultaneously the power of several loads (2, 3). Means (5, 6, 8, 9) are provided for this purpose to vary the current supply to the one load (2) in the opposite sense to the current supply to another load (3), preferably in reverse proportionality. In this way, the total power of the loads can always be kept constant. To this end, two rheostats (5, 8) are included, whose wipers (6, 9) are arranged on a common movement support (12). Each wiper (6, 9) can be moved individually on the movement support (12) and is arranged such that it can be fixed thereon. In this way, it is possible to control the desired power of the different loads for the temperature control of overheating and underheating in baking ovens, or lighting controls, by means of a single adjusting device. <IMAGE>

Abstract: In an internal combustion engine, a vibration period and a vibration amplitude are measured and the detected vibration period is compared with a natural vibration period prestored in accordance with a driving condition of the vehicle. If the detected vibration period is equal to the natural vibration period under the driving condition at which the vibration period is detected, it is determined that surging due to a torque variation of the engine is occurring. In this condition, the torque variation is controlled to be a predetermined value by increasing an air-fuel ratio or decreasing an amount of EGR when the detected vibration amplitude is smaller than a predetermined value, and the torque variation is controlled to a predetermined value by decreasing an air-fuel ratio or increasing an amount of EGR when the detected vibration amplitude is larger than a predetermined value, and accordingly, the driveability and emission rate are improved.

Abstract: The separating and dewatering of solids from glutinous liquids by means of separators of which the pressing force is built up by a screw is hindered by the high viscosity of the liquids; to permit separating and dewatering, oscillations are introduced into the filling space of the separator, the effect of which oscillations continues into the entry region of the screen pack, brings about a reduction in the viscosity of the glutinous liquid and thus permits the gravity dewatering necessary for separating the solids. For this purpose, a vibrator (4) is provided outside the filling space (2), the oscillations of which vibrator can be transferred via supporting ribs (5) to an oscillator (6) arranged in the liquid, a membrane (7) closing off the inner space of the separator and the oscillating elements being supported by springs or rubber buffers (11) and able to move correspondingly in the vertical direction.

Abstract: The removal of excess fluid from a test strip should be performed in a consistent manner to provide consistent results. To eliminate user variability introduced by manual blotting techniques, the device of the present invention wipes fluid from a test strip as the test strip is passed beneath a blade. The one-piece device is made of plastic so that it may be manufactured inexpensively and disposed of after use. The wiping device can also be integrated with an end cap, so that the wiping device can be attached to the end of an instrument, such as a lancet. To obtain a blood sample, for instance, the user inserts a test strip into the wiping device, where it is held while the blood sample is taken. The user deposits the blood sample onto the test strip and pulls the test strip through the wiping device. The blade removes a portion of the blood sample to provide a consistent wiping action which is not influenced by user variability. Alternative embodiments of the wiping device include apertures for viewing the test strip after wiping and colors adjacent the apertures for comparing the color of a reagent pad on the test strip after interaction with the body fluid.

Abstract: In order to determine the relative position of an object with respect to another object, the distance between the two objects needs to be known at one point and one angle. This angle can be determined very precisely in a mean distance range (</= 10 m) by means of ultrasound by using two ultrasonic receivers to evaluate the echo of a sound pulse, emanating from an ultrasonic generator, in terms of the phase difference of the received echo signals. The distance is determined in this case by measuring the propagation time in a known way. <IMAGE>

Abstract: A collision detector (12 ) for a vehicle (10), shown in Figure 1, comprises a waveguide (14) which is locatable on and acoustically isolated from the vehicle. The waveguide allows stress waves to propagate therethrough, and the waveguide is arranged to produce stress wave activity when the waveguide is deformed due to a collision. A pair of transducers (20A,20B) are acoustically coupled to the waveguide (14) and the transducers (20A,20B) convert any stress waves into electrical signals. A processor (24) analyses the electrical signals and gives an output signal to indicate the occurrence of a collision. The transducers (20A,20B) detect different frequency bands and the processor (24) compares the electrical signals and indicates the occurrence of a crash if the ratio or difference is greater than a predetermined value. The waveguide is a metallic member which has a glass coating (16) and a protective coating (18). Alternatively the waveguide (34) may be a fibre reinforced plastic, tin, or a metallic member which has an interface with a semi-rigid plastic member.
