Abstract: Presse hydraulique universelle pour le surmoulage par injection de matières à mouler, du genre comprenant deux unités d'injection, montées sur un support commun, chaque unité d'injection étant apte à recevoir dans sa trémie d'alimentation une matière à mouler différente de celle de l'autre unité d'injection, un mouvement de rotation relatif de ces unités d'injection et des moules permettant la réalisation de pièces moulées en deux matières distinctes.  Cette presse est caractérisée en ce qu'elle comprend deux unités de fermeture parallèles et autonomes, montées non rotatives sur le bâti de la machine, chacune avec un moule et sa busette d'alimentation, les deux unités d'injection étant groupées en carrousel sur une potence mobile en rotation autour d'un axe situé entre les deux unités de fermeture et parallèles à celles-ci, chaque unité d'injection étant apte à venir en regard de l'une ou l'autre des unités de fermeture, par rotation de 180.degree. de la potence, pour permettre de réaliser dans le même moule les pièces formées de deux matières différentes, injectées à travers la même busette d'alimentation, le moule de chaque unité d'injection comprenant en outre une plaque mobile insérée entre ses deux parties et présentant deux empreintes aux profils spécifiques. La plaque est associée à un dispositif permettant de la déplacer, en synchronisme avec la rotation des deux unités d'injection, de manière à amener successivement la première empreinte et la seconde empreinte entre les deux parties du moule, respective ment pour le moulage de la première et de la seconde matière. Une application particulière est le moulage de joints hydrauliques formés d'un noyau central et de deux bagues antiextrusion.

Abstract: DIGITALLY SYNTHESIZED BACK-UP FREQUENCY                     ABSTRACT OF THE DISCLOSURE       A digitally synthesized frequency back-up circuit which, after removal or failure of applied A.C. power, will reproduce signals precisely indicative of each zero transi-tion point of the A.C. waveform.  A high frequency binary counter continually counts internally generated pulses and. at the end of each A.C. period, stores one-half the count, representing 180°, in a storage buffer,  When the A.C. fails, the inverted value of the buffer count is loaded into the counter which is incremented by the internally generated pulses to count only up to the value stored in the buffer, at which point the circuit generates an output pulse.  As long as the A.C. frequency remains. off, the counter will continue to reload from the buffer and count the value representing this 180° period.  An additional and separate buffer section in the circuit stores the binary count representing the 90° point in each A.C. cycle and continuously generates 90° output signals that may be used to control switches for transient-free operation of associated electrical devices.

Abstract: ABSTRACT OF THE DISCLOSURE A flow splitter apparatus positioned within a nuclear fuel bundle sectionalizes the bundle into a number of compart-ments and provides an unheated surface along which liquid coolant flows.  The splitter apparatus has a length equal to that of a fuel bundle, extends from the interior of the fuel bundle to the wall of the nuclear reactor channel and or from this wall to the inner portion of the bundle and competes with this wall for liquid coolant.  The flow splitter apparatus reduces the amount of steam-water stratification occurring in the bundle.

Abstract: METHOD FOR ERECTING A DECK ON A MARINE STRUCTURE          ABSTRACT OF THE DISCLOSURE            The present invention relates to a method for mounting a deck structure on a supporting structure designed to operate in marine surroundings.  The supporting struc-ture comprises a buoy and body, submerged while in operating position, and one or more towers, columns or legs, extended above sea level, designed to support the deck structure.  The supporting structure may either be of a type resting on the sea bed or of a semi-submersible type.  According to the present invention, the deck is brought, wholly or in sections, into position at the lower end of the tower(s).  The deck/ deck sections are then lifted into place using a system of cables or rods, anchored to the deck/deck sections, and lifting/clamping devices mounted on the supporting structure.  When the deck/deck section are in place, it/they are then preferably permanently secured to the tower(s).

Abstract: TRIM PRESS     ABSTRACT OF THE DISCLOSURE           A trim press for severing cup-shaped articles from a sheet of thermoplastic material in which the arti-cles have been integrally formed as by a vacuum forming operation.  A horizontally reciprocable punch is driven to sever articles positioned in a stationary die by a linkage arranged to drive the punch at a relatively slow speed during the severing operation to achieve a smooth shearing separation of the relatively soft thermoplastic material.          The sheet is fed into the die in step-by-step movement through vertical sheet guides fixedly mounted in a treadle which is reciprocated with the punch at a proportionate speed.  A flexible sheet guide connected between the guides in the treadle and a fixed point on the machine frame flexes to accommodate reciprocation of the treadle while contin-uously guiding the sheet to the guides on the treadle. Feed fingers mounted on the treadle advance the sheet to the die in step-by-step movement synchronized with the stroke of the punch.

Abstract: WEATHER-RESISTANT ARRANGEMENT FOR    OUTDOOR OUTLETS            ABSTRACT OF THE DISCLOSURE            Electrical devices of outdoor electrical receptacles are protected from weather conditions.  A protective cover and a waterproofing gasket are pivotally mounted on a plate for movement along a circular path between a fully closed position, in which the gasket prevents water from reaching the device, and a fully open position, in which access to the electrical device is permitted.  A leaf spring having a planar movable portion constantly and affirmatively urges the cover to the closed position.  In order to ensure a reliable and automatic return of the cover to the closed position, an anti-over-the-center stop prevents a leading end of the cover, which engages the planar spring portion at a contact zone, from moving the latter beyond an imaginary line which extends from the center of curvature of the circular path in a radial direction towards, and at a right angle to, the plane of the spring portion.  The cover is easily mounted by snap-type action to the plate under spring tension.
