IPC: G01R33/385
Filed: 1988-11-28
Abstract: The invention relates to a gradient coil system having x and y main coils in the embodiment as saddle coils with split inner arcs (split arc saddle coils). The coil arcs are split such that their magnetic flux increases with increasing distance from the plane of symmetry. According to the invention, y and x supplementary coils (23, 24 and 25, 26, respectively) are assigned to the y and x main coils (10, 11 and 12, 13), respectively, which supplementary coils are likewise constructed as saddle coils and whose aperture angle is smaller than 90 DEG  and which are arranged on the same cylindrical surface having the radius  rho 3. The magnitudes of the elementary saddle coils, which determine the gradient field, are coordinated with one another in such a way that the disturbing terms (Cn,m) of the series expansion of the gradient field are at least partially eliminated.

Abstract: Manually portable apparatus enabling high-resolution, two-dimensional infrared imaging of remote, non-contacting targets is described. An on-axis optical subsystem (12) consists of a single, single-faceted planar scanning mirror (20) that is reciprocable by stepper motors (36,38) about two orthogonal axes (22,24). Oriented at approximately 45° relative to the mirror's line-­of-sight axis (26) to a target (18), the scanning mirror (20) reflects infrared energy incident thereon toward a spherical converging mirror (30), which may be manually focused to change the distance between it and a single-element, non-­cryogenically cooled, heat-sensitive detector (34) located behind the scanning mirror (20). An ADC (44), a microprocessor (46) and a motor control circuit (45) provide means for imaging the target (18) by sampling the serial, conditioned output of the detector (34) in timed relation to the angular positions of the stepper motors (36,38), and transforming energy density data to temperature data in a two-dimensional, pixel array. Integral display means (16) are provided, by which a colorable infrared image may be viewed. In a proposed modification, a parabolic, rather than spherical, converging mirror is used. In another proposed modification, the detector interposes the scanning mirror and the converging mirror, insubstantially occluding the infrared enegy reflected by the former.

Abstract: Improved rape plants, seeds capable of forming the same, and a novel improved vegetable oil derived from the rapeseeds are provided. Such plants have the ability to yield a vegetable oil of increased heat stability in combination with other desirable traits. The increased stability of the vegetable oil is attributable to the presence of an unusually high oleic acid content in the rapeseeds which has been lacking in the available rape plants of the prior art. It has been found that the novel rape plants of the present invention reliably can be formed by mutagenesis followed by selection as described. The vegetable oil produced by the improved rape plants of the present invention is particularly well suited for use as a frying oil wherein the increased stability at elevated temperatures is of prime importance. In a preferred embodiment wherein the vegetable oil is used as a frying oil, the alpha-linolenic acid content concomitantly is reduced which additionally imparts an increased oxidative stability.

Abstract: Un appareil d'impression (20) comprend une série de sources de rayonnement en forme de points (30), telles que des diodes électroluminescentes, disposées en une rangée de façon à permettre l'exposition d'un support d'enregistrement. Un organe logique (43) est prévu pour déterminer lesquelles des sources de rayonnement en forme de points doivent être choisies pour l'excitation. Un conducteur de courant (49) comprend un organe (44) réagissant à l'organe logique (43) pour fournir du courant électrique aux sources de rayonnement (30) choisies. Le conducteur de courant (49) comprend un miroir de courant comportant un circuit principal (Q2, Q1, 38) servant à produire un courant de référence (IREF) et plusieurs circuits asservis (Q13, 30) destinés à fournir les courants d'attaque correspondants aux sources de rayonnement (30) choisies pour l'excitation. Le circuit principal comprend une résistance (38) d'un type permettant, au moins avant le réglage, un réglage essentiellement continu du courant d'attaque à l'intérieur d'une plage de valeurs de résistance. Deux alimentations indépendantes (P1, P2) alimentent la tête d'impression. L'une des alimentations (P1) fournit l'énergie électrique au dispositif logique à une tension fixe appropriée aux dispositifs logiques. Une deuxième alimentation (P2) fournit l'énergie électrique servant à éclairer les sources de rayonnement en forme de points. Ainsi, la puissance alimentant les dispositifs logiques est isolée du bruit produit durant l'excitation des sources de rayonnement en forme de points. Une tension variable réglable est fournie par cette deuxième alimentation pour permettre la flexibilité du réglage des courants alimentant les sources de rayonnement en forme de points. Cette tension variable peut être réglée en fonction du vieillissement des diodes électroluminescentes ou de la température de la tête d'impression.

Title: Motion sensor.
Inventor: PHILIPP HARALD
IPC: G01V8/20
Filed: 1988-01-27
Abstract: An optical motion sensor comprises first (12) and second (22) light emitting diodes that emit complementary pulsed beams of infrared energy within a sensing region. A photodiode (18) sums the energies to produce a proportional sensing signal. An amplifier (34) AC coupled to the photodiode (18) blocks the constant portion of the sensing signal and passes any time varying signal portion to a sampling circuit (36). The sampling circuit (36) samples the sensing signal synchronous with the first pulsed beam and converts the time varying signal to a proportional detection signal. An integrator (38) coupled to the sampling circuit (36) responds to a detection signal by modulating the intensity of the second pulsed beam to null the time varying portion of the sensing signal. The motion sensor can be configured as a presence sensor by changing the time constant of the integrator (38). A slower time constant changes the rate at which the beam intensity is modulated and thus increases the duration of the detection signal.

Abstract: To determine the tangent or the line of penetration between a main body and an auxiliary body for flame cutting which touch or penetrate one another, first of all the mutual spatially fixed arrangement of the main body and the auxiliary body as well as, on both, in each case an area containing the common tangent or line of penetration are predetermined. The spatial contour of the two areas is then measured, and the measured values for the two contours are stored in a memory. Then, while maintaining the mutual spatial wall thickness of the main body and/or the auxiliary body, the common tangential trace or penetration trace closed upon itself is calculated from the stored values for the two areas, and the common tangent or line of penetration is calculated with the calculated values for the common tangential or penetration trace and the predetermined cross-section of the weld, and the flame cutting is controlled with these calculated values. <IMAGE>
