Abstract: A pipe assembly for use in production or drilling systems comprises a plurality of pipe members connected together in end-to-end relationship and a plurality of tubular conductor members electrically connected together in end-to-end relationship. The members have co-operating tapered or stepped portions, and/or screw-threaded portions whereby the pipe members support the conductor members in internal or external coaxial relationship. A logging unit can be moved along the assembly unit under fluid pressure to engage stop means for connecting the unit with the conductor members, or a logging unit can be incorporated in a pipe member wall. An outer pipe can surround the pipe assembly to provide with the pipe assembly interior two passages for the reception, flow or circulation of fluids, for example extracted oil and/or gas and barrier fluid.

Abstract: The invention relates to a process for obtaining a ceric oxide of controlled particle size distribution. 
<??>The invention also relates, as new industrial products, to a ceric oxide with new morphological characteristics. 
<??>The process is characterised in that it consists in hydrolysing an aqueous solution of a cerium(IV) salt in an acidic medium in the presence of an aqueous colloidal dispersion of a cerium(IV) compound, in separating off the precipitate obtained and in then subjecting it to a heat treatment. 
<??>The said process makes it possible to obtain a ceric oxide of a fine and narrow particle size distribution.

Title: Commande de traitement dynamique pour machines electrostatographiques
IPC: G03G15/00
Filed: 1988-03-28
Granted: 1992-05-27
Abstract: Une machine électrostatographique possède à la fois (1) des moyens de rétroaction pour régler des paramètres de commande du procédé en réponse à des variations à long terme du procédé électrostatographique et (2) des moyens d'action directe pour régler des paramètres de commande du procédé en réponse à des variations à court terme du procédé électrostatographique sans annuler l'effet des moyens de rétroaction. La moyenne d'un nombre prédéterminé de tensions de référence détectées de l'organe d'enregistrement associées à des zones d'image est comparée à la sortie de tension de référence d'une seule zone d'image produisant ainsi un signal de différence pour agir sur au moins un paramètre de commande du procédé pour la zone d'image unique, ce qui permet d'obtenir une commande du paramètre qui est sensible aux variations à court terme du signal de sortie et qui est insensible aux variations à long terme du signal de sortie.

Granted: 1991-06-12
Abstract: The invention describes an agricultural cultivator combination with a soil-tilling machine driven by power take-off shaft, with a follow- up roller and with a semi-mounted drill. To simplify the construction of such a cultivator combination, the invention is characterised in that collecting elements between the soil-tilling machine, follow-up roller and drill are so designed that, in the lowered working position, the soil-tilling machine can be lifted out freely over a limited stroke in relation to the follow-up roller and drill, and in such a way that, when the combination is lifted out, first the soil- tilling machine alone, then the drill, the follow-up roller thereby being relieved, and finally the follow-up roller are lifted out. <IMAGE>

IPC: G11B15/32

Abstract: Recording and/or reproducing apparatuses with magnetic tape storage have the disadvantage that, due to running over and over again and inadequacies in the tape guidance, step forming occurs in tape winding. This may result in damage to the tape and/or overloading of the motor. To avoid excessive step forming in tape winding, the new circuit has a counting device, which counts the number of tape movement sequences immediately following one after the other and returning to the original tape position. When a predetermined number of such movement sequences is reached, the entire tape is first of all rewound in the forward direction and then in the backward direction and, after the rewinding operation, the tape is wound back again to the original starting position. The rewinding operation can also be triggered by a motor current indicator and a threshold switch connected to the latter or by a control voltage which can be picked up from a control device of the motor or by the evaluation of signals at the output of tape- positioning pulse generators in a microprocessor. <IMAGE>

Date May 17, 1990.In a method for measuring the mass flow M of a fluid flowing through a pipe having a cross-sectional area A, the sound velocity c2 in the fluid is determined as well as the flow velocity v of the fluid by sing-around technique. Further, reflection technique is used which comprises measuring the amplitude both of an ultrasonic pulse which has been reflected in a boundary between a first and a second material having different acoustic impedances, and of an ultrasonic pulse which has been reflected in the boundary between the second material and the fluid, it being possible to determine the density of the fluid on the basis of the measured amplitudes, the sound velocity c2 in the fluid and the acoustic impedances of the first and the second material. The mass flow M is then obtainable as M=vxAx rho 2. A mass flowmeter especially has a transducer with a piezoelectric crystal (5), a first block (6) of a first material disposed adjacent said crystal, and a second block (7) of a second material disposed between the first block and the fluid, and calculating and amplitude metering means (10 and 12).

Abstract: Solutions containing pesticide wastes from greenhouses, for example, are decontaminated in a system including a soil bed reactor. Waste water from the greenhouse goes to a sample tank from which samples are withdrawn for assay of toxicity. Water from the sample tank goes to a holding tank, or to a downstream subsystem if toxicity level is low. Water in the holding tank is aerated to promote degradation of toxic materials. Water from the holding tank is applied near the upper surface of a layer of soil in the soil bed reactor. Air from the sample tank and holding tank, and intermittently, air containing pesticides from the greenhouse, is also passed through the layer of soil in the soil bed reactor. Microbial action in the soil degrades toxic materials in both the gaseous and liquid streams. Water from the soil bed reactor may then be discharged to a pond populated by plant and animal species which promote further degradation of any remaining toxic materials before the water is discharged from the system. A bioassay technique employing aquatic amphipods sensitive to water borne toxic materials is provided for routine screening of toxicity levels in the various solutions in the system.
