Abstract: Un injecteur de carburant pour moteurs à combustion interne comprend un corps (10) assujetti à un porte-injecteur (16) et un pointeau (18) de soupape axialement mobile dans le corps de l'injecteur et qui est soulevé du siège de la soupape par la pression du carburant, contre la sollicitation d'un agencement de ressorts de fermeture formé de deux ressorts cylindriques de compression (26, 28), afin d'injecter le carburant. La course totale du pointeau (18) de soupape se subdivise en une course préliminaire et en une course résiduelle. Afin d'obtenir un injecteur ayant un diamètre extérieur aussi réduit que possible, les deux ressorts de fermeture ont le même diamètre extérieur. Le premier ressort de fermeture (26), qui agit pendant la course préliminaire, s'appuie sur le fond (34) d'une chambre à ressort (24) et sur un boulon de pression (30) qui sollicite le pointeau (18). Le deuxième ressort de fermeture (28), qui agit avec le premier ressort de fermeture (26) pendant la course résiduelle, s'appuie également sur le fond de la chambre à ressorts par l'intermédiaire d'un deuxième boulon de pression (50) qui traverse le premier ressort de fermeture (26), et sur une douille intermédiaire (46) axialement mobile qui repose sur le corps (10) de l'injecteur. Les deux boulons de pression (30, 50) ont des têtes identiques (38, 52) à leurs extrémités mutuellement opposées, formées de doigts (40, 54) similaires à des griffes, la tête (40) d'un boulon de pression (30) enclenchant la tête (54) de l'autre boulon de pression (50).

Abstract: Un cylindre rigide (56) est mis en rotation autour de son axe de symétrie à une vitesse relativement élevée au moyen d'un moteur. Autour d'une partie de la circonférence du cylindre rotatif est enroulé un support d'image souple tel qu'un film photographique (14), auquel est appliquée une tension longitudinale au moyen d'un transport de film (10). Le film se conforme à la courbure du tambour, mais il est maintenu à une faible distance au-dessus de la surface du cylindre en équilibre entre les forces aérodynamiques créées par le cylindre rotatif et la tension appliquée du transport de film produisant ainsi un coussinet d'air à surface déformable. On utilise un faisceau analyseur afin d'écrire sur le film dans le sens des lignes. On utilise le mouvement longitudinal du film afin de procéder à une analyse dans le sens des pages.

Title: Method and apparatus for three-dimensional non-contact shape sensing.
Inventor: SCHULZ WALDEAN A
IPC: G01S17/86
Filed: 1991-10-11
Abstract: This method and apparatus optically samples numerous points on the surface of an object to remotely sense its shape utilizing two stages. The first stage employs a moveable non-contact scanner, which in normal operation sweeps a narrow beam of light across the object, illuminating a single point of the object at any given instant in time. The location of that point relative to the scanner is sensed by multiple linear photodetector arrays behind lenses in the scanner. These sense the location by measuring the relative angular parallax of the point. The second stage employs multiple fixed but widely separated photoelectronic sensors, similar to those in the scanner, to detect the locations of several light sources affixed to the scanner, thereby defining the absolute spatial positions and orientations of the scanner. Individual light sources are distinguished by time-multiplexing their on-off states. A coordinate computer calculates the absolute spatial positions where the scanner light beam is incident on the object at a given instant and continuously on a real time basis to generate a computer model of the object.

Abstract: A process is disclosed for co-processing spent nitric acid wash water with organic or biological wastes under wet oxidation conditions whereby the nitrogen content of the waste and the chemical oxygen demand and the nitrogen content of the nitric acid wash water and of the organic or biological wastes are significantly reduced. The nitric acid wash water is the waste stream generated by descaling wet oxidation reactors used for the treatment of organic or biological wastes, especially municipal wastes. The process of this invention can be carried out in conventional above ground equipment or in a subterranean, down-hole reactor having a vertical configuration which utilizes gravitational forces to provide a high pressure reaction environment. The nitric acid wash water and organic wastes are reacted with an oxidant at a temperature greater than 150°C and a pressure suffient to keep water in the liquid state. The nitric acid wash water is mixed with the organic waste or is introduced through the oxidant (preferably gaseous oxygen) inlet in such a manner that gas with water vapor and the remaining acid provides a liquid film so there are essentially no "dry spots" in the oxidant inlet lines.

Abstract: The invention relates to a method for determining the condition of an animal. To this end, movements of the animal are recorded by a first sensor during a certain time interval and converted into electrical signals. Said signals are conveyed to an arithmetic unit and processed to give a characteristic value for that time interval. This characteristic value is compared with a reference value. The sensor can be an acceleration sensor which is fixed to the animal. By means of a second sensor, the temperature of the animal can be recorded. Processing of the signals to give a characteristic value, and storage of these signals and the characteristic value can advantageously take place on the animal itself.

Abstract: A low power complementary MOSFET buffer circuit includes an input complementary MOSFET inverter (102) with a plurality of serially coupled diode-connected complementary MOSFETs (116,118) and an output complementary MOSFET inverter (104). An input digital signal drives one of the input inverter's MOSFET gates, and passes through the diode-connected MOSFETs to be biased, or level-shifted, prior to driving the input inverter's other MOSFET gate. Using the input digital signal directly and its biased equivalent ensures that, when each of the input inverter's MOSFETs is turned "off " in accordance with the logic level of the input digital signal, it is turned off more fully, thereby minimizing power dissipation. The inverted digital signal outputted from the input inverter drives both of the output inverter's MOSFET gates. The original input digital signal also drives one of the output inverter's MOSFET sources, whereby the low-to-high transition time of the output digital signal is reduced.

Abstract: An object of the present invention is to provide a wear-detection probe for a brake lining material which prevents a U-turned portion 61 of a detector K from shifting in a housing and avoids an increase of parts and steps of forming the probe 50. A hole 53 is formed around part of the inner periphery of an insulated electrical wire 60 in a housing 55 by drawing out of the housing 55 a pin 100 which serves to prevent the wire from being shifted in a mold upon mold-forming. A reinforcement bridge 54 is integrally formed in the hole 53 by the same resin material 70 as that 70 of the housing 55. Since the reinforcement bridge 54 is integrally formed in the hole 53 made by drawing the pin 100 out of the molded housing 55, it is possible to increase the strength of the probe 50 and to position the U-turned portion 61 in the housing 55 by the support of the reinforcement bridge 54. Also, it is possible to avoid an increase of parts and steps of producing the probe, since the reinforcement bridge is integrally formed in the molded housing.

Abstract: Measurement of the successive levels of a received signal is carried out by combining together the elements of groups of digitised samples (E1 to Em) which are taken from the signal during successive sampling windows (W) positioned by a local clock (H) kept well synchronised with the signal. The combination consists of an average weighted so as to take into account the transmission conditions: pass band of the path, bit rate required, background noise etc., which are capable of distorting the transmitted signals and hence of causing errors in the measurement of their actual levels. In order to achieve this weighting, the digital words (E1 to Em) of a same group are used to address a memory (10) in which values which should be chosen for each of them have been stashed previously. Application to the measurement of multilevel coded signals for example. <IMAGE>
