Abstract: Dans le procédé Bayer, destiné à produire de l'alumine à partir de la bauxite, l'efficacité du processus de séparation de boue rouge peut être sensiblement améliorée si le floculant (45) normalement utilisé est dilué avec un liquide de traitement (43c) obtenu au cours d'une étape de lavage ou de sédimentation précédente ou subséquente ou au cours de la même étape, et lorsque cette solution de floculant diluée est mélangée avec la bouillie de boue rouge (41) devant être séparée. Ceci permet d'utiliser moins de floculant que dans des procédés classiques, d'éviter d'utiliser de l'eau pour la dilution, et de produire une bouillie épaissie présentant une concentration accrue en boue.

Title: Circuit for detecting firing of an ultraviolet radiation detector tube.
Inventor: PETERSON SCOTT M
IPC: F23N5/08
Filed: 1992-12-04
Abstract: A driver circuit for an ultraviolet detector (UV) tube discriminates between firing of the UV tube in response to ultraviolet radiation impinging on it and a high resistance short between its output terminals. A capacitor charged on half cycles of AC power applied to the circuit discharges partially when the UV tube fires. This charge is transferred to a second capacitor to create a voltage displaced from ground. Each time the UV tube fires, the steep wave front generated thereby is passed by a high pass filter to a switch which momentarily grounds the voltage on the second capacitor through a resistor. The rapid change in the switch element's voltage signifies the presence of ultraviolet radiation on the UV tube.

Abstract: Au cas où le refroidissement du coeur serait insuffisant (panne très improbable des dispositifs de refroidissement et de refroidissement de secours), il est prévu de réduire la pression en fonction de la température. A cet effet, un tuyau à pression (23) faisant saillie à l'intérieur de la cuve sous pression (1) et passant par la paroi de ladite cuve (1B) de manière étanche, comporte au moins un orifice d'équilibre de pression (26) placé à l'intérieur du réacteur et fermé de façon étanche par un élément d'étanchéité fusible (25). Ce dernier se compose d'une soudure qui fond à une température limite comprise, par exemple, entre 600 et 700 °C et qui débloque l'orifice de compensation de pression (26), mais le maintient par contre fermé pendant la marche normale. Le tube à pression (23) est surtout un tuyau d'évacuation muni d'un orifice de réduction de la pression. Le tuyau à pression peut également être un tuyau de commande à pression avec lequel il est possible d'actionner une soupape d'évacuation prévue à l'extérieure de la cuve afin de réduire la pression du système.

On décrit aussi une tôle d'acier dont le traitement de surface a permis de réduire les défauts de revêtement. Cette dernière comporte une couche de revêtement ferrique placée juste au-dessous d'une couche de revêtement de zinc ou d'alliage de zinc, et une couche enrichie d'acier placée juste au-dessous de la couche de revêtement ferrique obtenue en appliquant un revêtement ferrique sur au moins un côté d'une tôle d'acier, de manière que le poids de ce revêtement varie entre 0,1 et 10 g/cm2 et que sa teneur en oxygène varie de 0,1 à 10 % en poids. On procède ensuite au recuit puis au revêtement par une couche de zinc ou d'alliage de zinc. On utilisera de préférence un bain de galvanoplastie contenant 0,1 à 10 g/l d'ions Fe3+ et un acide carboxylique ou un de ses sels métalliques alcalins pour le revêtement ferrique.

Abstract: On décrit un procédé de traitement concernant un patient présentant un niveau d'activité normal relatif à une protéine naturelle, ou dont l'état se caractérise par un niveau accru ou réduit de cette protéine naturelle. Ce procédé consiste à lui administrer un acide nucléique qui code pour un polypeptide agoniste ou inhibiteur soit de l'activité biologique due à cette protéine naturelle soit d'un effecteur naturel influant sur l'activité biologique de ladite protéine. L'agoniste ou l'inhibiteur est un polypeptide (c'est-à-dire une chaîne d'acides aminés qui en comporte au moins 2, et en général jusqu'à environ 500) exprimé à partir de l'acide nucléique lorsque ce dernier est présent chez le patient. Ce polypeptide agoniste ou inhibiteur agit in vivo de façon à augmenter ou diminuer, respectivement, l'activité biologique spécifique de la protéine naturelle ou de l'effecteur naturel du patient.

In one embodiment, a sperm sample is applied to the inlet port (16A), and the competitive migration of the sperm sample through the mesoscale flow channel (20, 40) is detected to serve as an indicator of sperm motility. In another embodiment, the substrate of the device is microfabricated with a sperm inlet port (16A), an egg nesting chamber (16B), and an elongate mesoscale flow channel (20, 40) communicating between the egg nesting chamber (16B) and the inlet port (16A). In this embodiment, a sperm sample is applied to the inlet port, and the sperm in the sample is permitted to competitively migrate from the inlet port (16A) through the channel (20, 40) to the egg nesting chamber (16B), where in vitro fertilization occurs. The devices of the invention may be used in a wide range of applications in the analysis of a sperm sample, including the analysis of sperm morphology or motility, to assess sperm binding properties, and for in vitro fertilization.

Abstract: A device for securing the safety of a worker, wherein a mechanically movable section is surrounded by a safety fence, a door lock means unlocked when a built-in solenoid is supplied with electric current from the outside and excited is provided to a door formed in the safety fence, and a door switch is unlocked when the mechanically movable section is stopped. Further, a movable section monitoring sensor is provided for monitoring whether the mechanically movable section is stopped or not, and, when the mechanically movable section is stopped, the movable section monitoring sensor produces an output signal of a logical value (1) corresponding to a high energetic state without performing NOT operation and energizes the solenoid of the lock door means in response to this output signal. With this arrangement, only when the mechanically movable section is stopped, the door lock means is unlocked. Furthermore, in case when the sensor is in trouble, the solenoid is not energized, whereby the door lock means is not unlocked, so that the safety of the worker can be reliably secured.

Abstract: Disclosed is a frame of eyeglasses made of aluminum alloy or any other light metal which prevents soldering or plating, and therefore could not be thought of being used as material of frames. Frame parts of aluminum alloy or such a light metal have soldering-permitted deposition layers formed thereon according to the present invention, thereby permitting the soldering of the frame parts into an integral frame form. Deposition layers are formed in the metallurgical penetration into the counter surface, and therefore, such deposition layers cannot be peeled off, thereby assuring the stout soldering. Thus, frames of eyeglasses can be made of aluminum alloy or any other light metal which could not be thought of being used in making frames of eyeglasses. Such light frames of eyeglasses are most desirable because persons do not feel tired even though they wear eyeglasses for a long time.
