Patent EP-0377478-A1 (EP)
Inventor: VREEDE RENE DE
IPC: B07C5/342
Filed: 1990-01-03
Abstract: The invention relates to an apparatus for inspecting bulk goods (6), having an average colour, said apparatus comprising: drivable conveyor means (5); dispensing means (4) for pouring the bulk goods on the conveyor means in such a way, that said goods form thereon a single layer; a light source (9, 10) for illuminating the bulk goods transported by said conveyor means; and a video camera (11) for forming first video signals corresponding to the picture of the bulk goods illuminated by said light source from the side of the video camera and a signal processing unit having a memory, in which previously said colour and the associated tolerance limits are stored; means for forming from the first video signals second video signals representative of the colour of the bulk goods observed by the video camera; comparing means for comparing the contents of the memory with the second video signals and generating a reporting signal in case of a detected difference. 
     In the prior art with the inspection of coloured objects a problem may occur as a result of the colour transition between the conveyor means and an object observed by the video camera. At a transition from the conveyor means to the object as a result hereof in the camera spurious and disturbing colour variations may occur around the object, that later have to be filtered out electronically in the signal processing unit. It cannot be avoided that such a filtering has negative consequences for the detection accuracy of colour deviations of the product. 
     In view thereof the invention provides an inspection apparatus of the type mentioned above, characterized in that the background observed by the video camera has substantially the same colour as correct bulk goods.

Abstract: The invention relates to a method for drying lengths of carrier material which have been printed with ink comprising an evaporable solvent. To maintain the concentration of the solvents evaporating from the prin­ting ink, this concentration has to be determined. As known apparatuses for measuring the concentration are expensive, prone to faults and need regular calibration, the present invention provides a method for calculating that concentration. According to said method the concen­tration of the evaporated solvents in the gas mixture is determined by measurement of the temperature and flow rate of a mixture to be supplied to the burner (2), and by measure­ment of the temperature of the gas mixture heated by the burner (2) and by measurement of the flow rate of the fuel supplied to the burner (2). More precisely the concentration is determined by calculation of the increase in heat of the gas mixture in the burner (2), the amount of heat supplied by the burner (2), and in which from the difference thereof the burning heat of the solvents is determined, after which with the known burning value thereof the concentra­tion is determined.

Abstract: A plurality of different reference voltages are generated. A set of differential conversion circuits has first input terminals subjected in common to an analog input signal and second input terminals subjected to the respective reference voltages, and converts differences between voltages at the first and second input terminals into differential output voltages. A first A/D conversion circuit compares the analog input signal with the reference voltages to perform a higher-order A/D conversion of the input analog signal. At least two of the differential output voltages are selected. An interval between the selected differential output voltages is divided, and divided voltages are generated in accordance with the division. A second A/D conversion circuit compares the divided voltages to perform a lower-order A/D conversion of the analog input signal.

Abstract: The disclosure concerns the fabrication of integrated circuits. To enable the making, in an integrated circuit, of an internal clock, the frequency of which is adjustable and does not depend on the general supply voltage Vcc of the circuit, a relaxation oscillator is used. This relaxation oscillator is built in the following way: weighted individual current sources may be selectively connected in parallel under the control of a register containing frequency adjusting data. These sources charge and discharge a capacitor. A threshold comparator determines a high threshold Vh and a low threshold Vb to trigger respectively the discharging and the charging of the capacitor. The difference Vh-Vb is made proportional to the currents of the elementary sources. Thus, even if the value of the currents varies as a function of the supply voltage, the thresholds vary at the same time and the period of the oscillator does not vary.

Abstract: Procédé permettant de purifier des oligonucléotides synthétiques cibles de longueur totale d'un mélange d'oligonucléotides, notamment dans un mélange contenant des séquences tronquées ou défectueuses. Ledit procédé consiste à fixer une séquence en nucléotides courte et complémentaire à l'extrémité 5' d'un oligonucléotide cible sur un substrat solide. La complémentarité entre la plupart des nucléotides 5' de l'oligonucléotide cible et l'oligonucléotide lié se traduit par une hybridisation servant à retenir l'oligonuclétide cible. Les séquences tronquées ou défectueuses qui n'ont pas l'extrémité 5' complémentaire à l'oligonucléotide lié ne s'hybrident pas et ne sont donc pas retenues. Grâce à ce procédé, il est possible de purifier des quantités en grammes d'acides désoxyribonucléiques synthétiques, ou d'acides ribonucléiques, et de séquences présentant des modifications, telles que celles présentes sur le squelette du phosphate. Les séquences de nucléotides liées au substrat sont stables dans ces conditions de purification et peuvent en conséquence être réutilisées.

IPC: G01P3/48
Filed: 1990-08-08
Abstract: A device for measuring lengths, angles and the like comprises two components which can move relative to each other and which together form a magnetic circuit. One component comprises a sequence of alternating ridges of relatively high and relatively low magnetic conductivity, spaced at a predetermined interval apart in the direction of relative movement. The other component comprises at least one measuring element with a sensor which responds to fluctuations induced by the relative movement of the two components inthe magnetic flux produced by a magnetic flux source and guided by the magnetic circuit. In the measuring element, several partial, adjacent magnetic fluxes aligned in the direction of the mutual movement of the two components and separated in function of the spacing between the ridges jointly form a total flux and the at least one sensor is arranged and/or designed so that it emits an output signal which is a function of the sum of the partial magnetic fluxes.

Abstract: Procédé de commande de servomoteur à boucle fermée présentant d'excellentes caractéristiques de stabilité de commande et de réaction. Dans la partie de régulation de vitesse (10) d'un servosystème, le produit de la valeur intégrale d'une erreur de vitesse (epsilon), que l'on obtient en soustrayant la valeur de sortie (Vf(m)) d'un détecteur de vitesse d'une commande de vitesse et d'un gain d'intégration (k1), est ajouté au produit d'une commande de vitesse (Vc) et d'un gain proportionnel (k2). Le produit de la valeur de sortie (Vf(m)) d'un détectuer de vitesse et d'une valeur (1 - alpha) est additionné au produit d'une vitesse réelle (Vf(s)) d'une pièce mobile de la machine, par la différentiation de la valeur de sortie (Pf) d'un transducteur de position et d'une valeur paramétrique (alpha). Une valeur de commande de couple (Tc), que l'on obtient en soustrayant le produit de cette valeur d'addition et le gain proportionnel (k2) de la valeur d'addition (k2Vc + epsilonk1/S) qui est obtenue d'abord, est incrémentée ou décrémentée en fonction de la différence (Vf(m) - Vf(s)) entre les vitesses du servomoteur et la pièce mobile de la machine, ce qui augmente ou diminue le couple de sortie du moteur de manière à éliminer la différence de vitesse. Cet agencement permet d'empêcher la mise en vibration du système mécanique sans réduire le gain de l'asservissement et garantit la stabilité et les caractéristiques de réaction du servosystème.
