Abstract: A quick-release and positive locking mechanism adapted for use on tools for receiving removable sockets (20), and particularly adapted for use on extension bars (10) of the type frequently employed with socket wrenches. One form the mechanism comprises a drive stud (14) having a diagonally disposed bore (26) or opening extending therethrough and having a movable member (30) mounted in said bore with its lower end adapted to extend beyond the contour of the bar and into a recess (24) in the socket or like attachment to hold the same when in one position and to be withdrawn from said recess to release the socket or like attachment in another position and with its upper end extending beyond the contour of the drive stud above said socket or like attachment for access for manual movement. The angle of the bore or opening and the construction of the pin is such that force exerted to remove an attached socket or other attachment cannot generate a component of force on said movable member in the direction of its possible movement such as would cause an accidental or unintended release of said socket.

IPC: C21C5/56

Abstract: In a continuous steelmaking method, a molten metal bath is maintained within a rotary furnace heated by oxy-fuel burners at the charge and discharge ends. Metallic iron charge material such as iron and steel scrap or sponge iron is preheated primarily by heat transferred from the furnace exhaust gases, on an enclosed recuperative conveyor before being introduced through the charge end opening. Molten metal is withdrawn through a siphon tube submerged in the bath through the furnace discharge end opening into a vacuum chamber which is part of an integral vacuum chamber-tundish combination incorporating a molten metal column under vacuum in one leg and a molten steel tundish casting pool under atmospheric pressure as the other leg, connected via a submerged channel. As steel is cast out of the tundish through a submerged nozzle, it is replenished by way of the column from vacuum-induced flow through the siphon tube, metal surface levels in column and tundish remaining substantially constant once casting has been established. Several means are provided for regulating withdrawal and casting rate, including the use of slide-gate valves and varying the vacuum pressure, and also a procedure for initiating the method without pre-filling the vacuum chamber-tundish with starting molten metal. Optional features include oxygen injection into the vacuum chamber, argon stirring for degassing and alloy additions through a sealed conduit or by injection. According to the invention, continuous flow of material may be realized from charging and preheating of the charge through to continuous introduction of the steel into the casting molds, with only a very small vertical descent between charging and pouring. Other salient advantages include very high overall energy efficiency, low capital costs, negligible furnace to mold temperature losses, efficient steel degassing, high alloy recoveries, flexible steel chemistry control, wide range of acceptable charge materials, and clean pollution-free operation.

Abstract: L'émetteur est muni de moyens séparés d'émission d'une première et d'une deuxième fréquence. Il est contenu dans un logement pouvant flotter. L'émetteur est relié par un commutateur à une batterie. Les moyens d'émission sont constitués par un oscillateur commun à quartz connecté avec des multiplicateurs de fréquence qui sont connectés à des étages d'attaque et des étages finaux haute fréquence. Ces derniers sont connectés à une antenne d'émission qui s'étend depuis le logement, ainsi qu'à un générateur de signaux de modulation des fréquences émises. Un problème se pose lors du sauvetage en mer en ce qui concerne les dimensions et le poids de l'appareil en particulier lorsque celui-ci est porté en permanence par une personne. Une diminution de ces paramètres n'est pas possible au-delà d'une certaine limite du fait de la capacité de la batterie et du rendement d'émission. Pour résoudre ce problème sans diminuer la portée de l'émission et la durée de celle-ci en diminuant presque de moitié la dimension de la batterie ainsi que l'énergie que celle-ci doit livrer, on incorpore au premier (11) et au deuxième (13) moyen d'émission un dispositif de commande cadencée (par exemple 36) qui met en fonction alternativement les deux moyens (11, 13). Ainsi la sollicitation de la batterie se réduit à celle nécessaire pour un seul dispositif d'émission.

Abstract: Une cellule électrochimique primaire, en forme de disque, fonctionne de façon à donner un avertissement vers la fin de la décharge de la cellule, en signalant la fin prochaine de la durée de vie de la cellule. La cellule (1) comprend une paire d'éléments cathodiques en carbone poreux, plats et écartés l'un de l'autre (5, 9), chacun ayant la forme d'un disque, disposés dans une petite enceinte métallique (2), en général plate, de la cellule, une structure anodique généralement plate (7) étant disposée entre les deux éléments cathodiques en carbone (5, 9). La structure anodique (7) comprend un premier (15) et un deuxième (16) éléments électrochimiquement actifs, du lithium et du calcium, par exemple, ayant des potentiels d'oxydation différents dans la cellule et se consumant par une action électrochimique dans la cellule pendant la décharge de la cellule. La consommation des éléments actifs pendant la décharge de la cellule a pour conséquence l'établissement de tensions de fonctionnement différentes et distinctes pour la cellule. Les éléments actifs sont agencés l'un par rapport à l'autre detelle façon que l'élément actif ayant un potentiel d'oxydation plus élevé (c'est-à-dire le lithium (15)) se consume avant l'autre élément actif (c'est-à-dire, le calcium (16)). Le changement de la valeur de la tension de fonctionnement de la cellule dû à la consommation successive des deux éléments actifs est détecté afin de donner une indication qui signale la fin prochaine de la durée de vie de la cellule.

Abstract: La présente invention se rapporte à des caméras à positrons dans lesquelles une zone (17, 18) de détecteurs (15, 16) est agencée pour détecter les émissions de photons gamma à partir d'un isotope émetteur de positrons injecté dans un objet à examiner. L'émission détectée est traitée électroniquement et convertie en des affichages tels que des images. En augmentant le nombre de détecteurs (15, 16) on améliore la définition. Les détecteurs (15, 16) sont constitués par des détecteurs de scintillation ou des cristaux reliés optiquement aux tubes photomultiplicateurs (14). Selon l'invention le nombre de détecteurs de scintillation (15, 16) est augmenté sans augmenter le nombre de tubes photomultiplicateurs (14), l'augmentation du nombre de détecteurs de scintillation (15, 16) pour chaque tube photomultiplicateur (14) étant possible en utilisant des détecteurs de scintillation (15, 16) qui tous pour chaque tube photomultiplicateur présentent ses caractéristiques propres.

Abstract: A focussing error detecting apparatus includes a compound lens (30) and a photo-detector (8) disposed behind the lens (30). The lens (30) comprises a pair of lens regions (30a, 30b) divided by a boundary plane (T) including an optical axis 0 of light incident on the lens (30), the lens regions (30a, 30b) having back-focal lengths which are differentfrom each other, and optical axes (O 1 O 2 ) of the lens regions (30a, 30b) being spaced apart from each other. The photo-detector (8) is so placed that the photo-detecting face thereof is at a middle position on the optical axis 0 of the incident light between focal points at which the emitted light from the lens regions (30a, 30b) is focussed. The photo-detector (8) comprises first and second photo-detecting elements (8A, 8B) for receiving the emitted light which has passed through the first lens region (30a) at outer and inner regions relative to the boundary plane (T), and third and fourth photo-detecting elements (8C, 8D) for receiving the emitted light which has passed through the second lens region (30b) at outer and inner regions relative to the boundary plane (T). Based upon a difference between a sum of signals from the first and fourth photo-detecting elements (8A, 8D) and a sum of signals from the second and third photo-detecting elements (8B, 8C), a focussing error signal is produced.
