Abstract: ABSTRACT OF THE DISCLOSURE       A limited deflection spring for a box spring assembly which includes a generally rectangular frame, a plurality of the wire springs mounted on the frame, and a wire grid supported on the upper ends of the springs so that the grid and springs cooperate to yieldably resist downwardly directed bedding loads.  Each of the springs is formed at its upper end with an attaching portion that is structured so that it can readily be connected to the grid and its lower end so that it will engage the frame after a predetermined deflection.  The spring is installed merely by moving it from an initial position to an interlocked position.  This structure enables assembly of the grid and the springs without the requirement for the usual attaching clips.

Abstract: ABSTRACT OF THE DISCLOSURE         A method for determining a time dependent change in the luminescent polarization of a living cell-dye system having a luminescent probe associated with the living cells, where the living cell-dye system is dispersed in a medium.  The method comprises introducing a dye into the medium to associate a luminescent probe with the living cells of the living cell-dye system where luminescent components of the dye, which are unassociated with the living cells, increase in concentration over time in the medium to provide a background luminescence.  Polarized light in a distinct orientation having a significant vertical orthogonal component is irradiated onto the living cell-dye system and medium.  The polarized light emissions from the luminescent probe associated with the living cells and luminescent components in the medium are analyzed in two distinct orientations representing horizontal and vertical orthogonal components of the polarized light emissions to determine the time dependence of the components of the polarized emissions from the luminescent probe associated with the living cells of the system and the luminescent components of the medium. The steps of generating polarized light and analyzing the polarized light emissions are conducted during a period commencing at times greater than the luminescence lifetime of the living cell-dye system and continuing until the background luminescence from the system medium significantly affects the polarized light emission intensities from the luminescent probe associated with the living cells of the system.

Abstract: ABSTRACT OF THE INVENTION         This invention is directed to a novel method and apparatus for constructing artificial islands in relatively shallow bodies of water such as lakes, seas and oceans for use in drilling oil and gas wells and installing storage and production platforms.  The method of building an artificial island in a water-bound area comprises converting an oil tanker, oil/bulk/ore, or oil/ore (O, O/B/O, O/O) hull so that it can be partially submerged by liquid or solid ballast; transporting the hull to the water-bound area where the artificial island is to be created; and partially submerging the hull with liquid or solid ballast so that the bottom of the hull is founded on the bottom of the water body, while a portion of the hull remains above the water level.  The apparatus capable of forming a temporary or permanent artificial island in a relatively shallow body of water comprises a tanker vessel, and means on the vessel for taking on ballast in the hull thereof to thereby partially submerge the vessel so that is rests on the bottom of the water body while the deck of the hull remains above water.

An insert (14) is guided only in the housing bore (10) and is connected by way of a rotary coupling (38) which permits play to a setting element (15) which serves for rotary adjustment. The circumferential wall (41) of the insert (14) abuts the base (?) with its end under spring force and circumferentially bounds a control orifice (42) which co-operates with the fixed opening (11). The control orifice is covered up to at least one residual through-passage (45) to the valve chamber (4) by a skirt (44).  The insert can be adjusted by small forces.  The danger of jamming is substan-tially eliminated. Fig. 1.

Abstract: L'invention concerne un digesteur pour la production en continu de biométhane à partir de substances organiques, comprenant une cuve à l'intérieur de laquelle se trouve un pilier central sur lequel prend appui la partie supérieure du digesteur. L'appareil selon l'invention est caractérisé par le fait que toute la partie supérieure du digesteur et son pilier central d'appui dont elle est solidaire mécaniquement sont mobiles en rotation autour de l'axe central vertical de la cuve, la partie supérieure du digesteur prenant appui par l'intermédiaire de galets à la face supérieure des parois latérales de la cuve et sur le pilier central qui lui-même prend appui sur le plancher de la cuve par l'intermédiaire d'une crapaudine. La partie centrale de la cuve est occupée par un compartiment cylindrique définissant un compartiment primaire et dont l'axe est confondu avec l'axe de la cuve du digesteur. La cuve est traversée par une cloison fixe disposée selon un rayon de la cuve, et une cloison mobile liée rigidement à la partie supérieure du digesteur et au pilier central effectuant des aller et retour circulaires de façon à balayer tout le volume de la cuve en dehors du compartiment primaire. A la partie supérieure de la cloison mobile sont fixées une pompe de recirculation et une pompe d'introduction de sorte que pendant le déplacement de la cloison mobile, la pompe de recirculation fait passer de part et d'autre de la cloison tout le volume balayé pendant le déplacement et simultanément la pompe d'introduction introduit les produits en provenance de la base du compartiment primaire dans une veine des produits en cours de déplacement sous l'action de la pompe de recirculation. Le biogaz est recueilli par une bache souple solidaire de la partie supérieure mobile du digesteur. Les avantages apportés par l'invention sont la disparition totale des problèmes posés par la croûte et par la sédimentation des boues au fond du digesteur, ainsi que l'apport régulier et homogène de nutriments dans toute la masse des produits en cours de digestion, ce qui est un facteur très important pour le rendement et ce qui permet une bonne utilisation du pouvoir tampon des produits en cours de fermentation.

Each channel has a respective identity which is transmitted in the traffic of that channel and in the event of a protection switch is identified in the protection channel traffic.  A protection switch is effected by detecting a channel failure at the receive end of a span, transmitting a protection request on the return channel back to the transmit end of the span, and using this request in a controller for the channel to effect a protection switch, using an individual selector for the channel, if a priority scheme allows.  The controllers are enabled or disabled under software control following a protection switch in accordance with the prevailing priority scheme.
