Patent EP-0513431-A1 (EP)
Inventor: BLACH JOSEF A
IPC: B29C48/41
Filed: 1991-09-04
Abstract: The application relates to a device for the compounding and extrusion of viscous, elastic, plastic and similar materials having a plurality of screw shafts (2, 3) rotating in a common housing (1). This device is to be designed in such a manner that the resistance to which the material to be processed in the device is subjected can be sensitively controlled without the material being subjected to impermissibly severe stressing. The screw-shaft extruder therefore has an enlarged radial play (8, 9) in the region of the saddle over a relatively large length of the housing, which play is disposed upstream or downstream of the deflection in the region of the saddle acting as a natural throttle. <IMAGE>

Abstract: In a known coffee or tea machine, which has a fresh water container (1), a water filter (3) arranged below it, and an adjoining water outlet (5) which opens out into an instant heater (2), the problem arises, due to the increased flow resistance, caused by the water filter, of the water flowing into the instant heater with a decreasing filling level in the fresh water container, that the quantity remaining in the water filter runs off only in such a small amount that undesirable vapour formation occurs in the instant heater. In order that filtered water can flow into the instant heater continuously throughout the entire brewing operation, a water reservoir (4) is provided to the sides of and/or below the water filter (3), which water reservoir is connected so as to communicate with said water filter and opens out into the water outlet (5). <IMAGE>

Abstract: A method and an apparatus are proposed for measuring the cross section of electrical wires (insulated conductors), in particular of a central and/or high-voltage wire. Seen in profile cross section, the wire (50) comprises a copper conductor, an inner semiconductor, an insulation and an outer semiconductor and is produced in an extruder (90) having a suitably placed crosslinking section (40). To achieve a uniform distribution of the two semiconductor layers and of the insulation layer, the wire (50) is irradiated immediately on emerging from the crosslinking section (40) and values determined in this way are used to correct the true adjustment in the extruder. <IMAGE>

Abstract: Sigma-delta converter for converting an analog input signal into a sigma-delta code. The converter includes a threshold device (222) for generating an output and feedback signal, a filter receiving said analog input signal and said feedback signal by means of at least one feedback loop. The sigma-delta converter further includes means (221, 222) located in said at least feedback loop for performing a return-to-zero of the sigma-delta code generated by said threshold device at every period of the sigma delta clock whereby said sigma-delta converter is insensitive to the asymmetry of the rise and fall time of the thresholds device. That results in an increase of the signal-to-noise ratio and the linearity of the converter allowing the manufacture of a sigma-delta convertors with discrete components without requiring the development of an integrated circuit using switched capacitor technology.

Abstract: Dans les transmissions à variation discontinue de la vitesse connues, aucun couple n'est transmis à la chaîne cinématique quand on passe une vitesse. Le nouveau procédé doit solutionner ce problème et, en même temps, assurer un couple optimum. Quand on passe les vitesses, une rapport supplémentaire est engagé. Le couple dérivé sur ce rapport supplémentaire provoque immédiatement une baisse du régime du moteur. La variation du régime dépend directement du couple dérivé et est réduite par l'intermédiaire d'une boucle d'asservissement fermée.

Patent EP-0515506-A1 (EP)
Inventor: BLOCH WILL
IPC: C08J7/046
Filed: 1991-02-15
Abstract: Improvements to the polymerase chain reaction (PCR), a process for in vitro enzymatic amplification of specific nucleic acid sequences, can be achieved by changing the way that PCR reagents are mixed and the enzymatic reaction is started and by the replacement of mineral oil, commonly used as a vapor barrier to minimize solvent evaporation, by a grease or wax. The use of such mixtures allows for the delay of reagent mixing until the first heating step of a PCR amplification, thereby reducing the enzymatic generation of nonspecific products which occurs when a complete mixture of PCR reagents, with or without test sample, stands at room temperature or below. These mixtures increase the shelf-life of PCR reagents and increase protection of the laboratory environment against contamination by PCR product.

Abstract: On réduit l'espacement des lignes au minimum et on augmente l'uniformité de l'espacement des lignes dans des transistors à film mince en utilisant une métallisation source/drain ayant une première couche relativement mince d'un premier conducteur et une seconde couche relativement épaisse d'un second conducteur. Le second conducteur est choisi de sorte qu'on puisse l'attaquer de préférence en présence du premier conducteur pour que celui-ci agisse comme barrière à l'attaque de l'agent d'attaque utilisé pour configurer la portion du second conducteur de la métallisation source/drain. Cette attaque s'effectue de préférence à sec. L'attaque à sec permet généralement un contrôle sensiblement meilleur de la largeur des lignes que l'attaque par voie humide. L'attaque du second conducteur peut s'effectuer par un procédé d'attaque à sec qui attaque la photoréserve sensiblement à la même cadence que le second conducteur de sorte que l'on obtient une pente sensiblement de 45° de la paroi latérale du second conducteur, ce qui améliore la qualité de passivation effectuée par le dépôt ultérieur d'une couche de passivation de conformation.
