Abstract: ABSTRACT:   An extendible structure of the invention is constructed by connecting the radially projecting legs of the spacer with differing longerons through the joints, and then fastening one joint with adjacent another joint at a diagonally opposed position with a bridle.  In the extended state of the structure, the spacers are within a plane which is substantially perpendicular to the direc-tion of extension of the structure and the bridles are extended in the diagonal lines between the adjacent joints to thereby form the longerons in a mast-shaped three-dimensional structure, while, in the collapsed state of the structure, the longerons are collapsed in a loop form and the spacers are laid one upon another inside the loop formed by the longerons to thereby produce a cylindrical form in its outer appearance.

Abstract: Appareil et méthode pour échantillonnage continu non remanié du till de fond non plastique par carottage à rotation. Le terme till de fond non plastique (sans cohésion) correspond à un dépôt glaciaire hétérogène, constitué d'un mélange non stratifié et non trié de silt, de sable, de gravier, de cailloux, de blocs et sans particules d'argile. En géotechnique, on classifie ce matériau d'une façon générale, comme un sable silteux graveleux avec un pourcentage variable de cailloux et de blocs (la matrice sans cohésion étant constituée de silt et de sable). L'appareil comprend entre autre un ensemble de train de tiges, un carottier triple et un trépan de conception nouvelle d'un diamètre préchoisi. Le train de tiges est tourné à une vitesse de rotation (rpm) prédéterminée en fonction du diamètre du trépan et la pénétration du carottier dans le sol se fait à une vitesse d'avancement prédéterminée. Le trépan est muni d'une couronne sertie de diamants selon un patron prédéterminé. Le système de canalisation de fluide traverse le trépan et la couronne. Le fluide sort à la face de la couronne, et circule de façon à ne pas toucher l'échantillon, prévenant ainsi le délavage de la matrice du sol. La boue utilisée a une viscosité très élevée soit un minimum de 70 sec. mesurée sur l'entonnoir Marsh. La vitesse de circulation est maintenue à une valeur très basse et prédéterminée. Un tube interne est suspendu dans le carottier afin d'y recevoir l'échantillon non remanié du sol. La récupération de l'échantillon se fait en retirant le tube intérieur du carottier au moyen d'un système à câble et durant cette opération la circulation de la boue est inversée.

Abstract: ABSTRACT        A cutting tool, preferably in the form of a scalpel, microtome or razor blade is fabricated from single crystal mater-ial such as aluminum oxide with a preferential etching process to produce a radius of curvature less than 100 Angstroms on the edge. Depending upon the etchant, the crystallographic orient-ation of the blank and the resulting different etch rates on blade surfaces, the preferential etching process not only sharp-ens a preformed edge but also, in one embodiment, produces an opposing edge which meets the sharpened edge at a point, thereby to produce a particularly efficient scalpel blade configuration having two cutting edges converging at a point for plunging and cutting. With respect to the sharpening of the cutting edge, consistent with all other blade forming requirements, the subject blade is made to a maximum sharpness by utilizing a maximum ratio of bevel plane etch rate to edge plane etch rate. This maximum ratio maximizes the edge sharpness when a steady state etching geometry has been achieved. In one embodiment, and for a given edge sharpness, blade drag is minimized by selecting the crysta-llographic orientation and etchant such that the etchant chemic-ally polishes the bevels and maintains the planarity of the bevel planes. In order to achieve identical ething of the bevels meeting at the blade edge and thus maintain original blade geometry, the blank can be oriented such that the edge forming planes are crystallographically identical planes.

Abstract: Case 4784 PROCESS FOR CLEANING VESSELS CONTAINING SULFUR DICHLORIDE  ABSTRACT OF THE DISCLOSURE An improved process for cleaning vessels containing liquid sulfur dichloride is disclosed.  The sulfur dichloride is first removed from the vessel leaving a heel (residue) of liquid and solid material on the bottom of the vessel.  The remaining liquid is vaporized by heating the vessel, and the vapors are removed by vacuum and purging.  The vessel is purged with an inert gas during heating to prevent exothermic reactions and the formation of toxic reaction products, and to assist in removal of vapors from the vessel.  The solid residue remaining in the vessel is then removed from both the bottom and wall portions.     In a preferred aspect, the present invention is particularly applicable to cleaning railroad tank cars which are used to transport sulfur dichloride.  The tank car is advantageously insulated during the heating step by enclosing the tank car in a fiberglass blanket, and the heat is supplied by a hot air blower.  The liquid and gaseous materials removed from the tank car are subsequently neutralized by reaction with sodium hydroxide.

Abstract: ABSTRACT OF THE INVENTION       An interface apparatus utilizing data encoding/decoding methods having particular application for use in interfacing data processing and telecommunication equipment is disclosed.  The interface apparatus includes an encoder for encoding inputted data for transmission on a telecommunication system, and a decoder to receive the encoded data and decode the data stream such that it identically represents data originally provided to the encoder.  The present invention detects channels in the inputted data which contain a predetermined value of bits, and stores the channel numbers of these detected channels in digital storage means.  These detected channels are then deleted from the data stream, and the remaining inputted data in each of the data channels is shifted such that data previously located in the first data channel is inserted in the data channel offset by the number of channels stored in the storage means.  The present invention then inserts the channel numbers previously stored in the storage means in empty data channels created by the shifting process.  This encoded data stream is when transmitted, and is received by another unit of the present invention coupled to receiving data processing equipment.  A decoder of the present invention detects the channel numbers previously inserted in the data channnels and stores these numbers in a channel address buffer.  The decoder deletes the channel numbers in the data Channels and shifts the data in the remaining channels, such that the received data is sequentially inserted beginning in the first data channel.  Previously defined predetermined values are inserted in the now empty data channels which are identified by the channel numbers stored in the channel address buffer.

Abstract: FLEXIBLE CONTAINER HAVING SELF-SEALING DISPENSING VALVE             TO PERMIT INVERTED STORAGE     ABSTRACT A resiliently deformable container having at least one discharge orifice equipped with a self-sealing dispensing valve, said valve having a resiliently deformable, concave shaped portion with its perimeter sealingly secured across the container's discharge orifice. The self-sealing valve is secured across the orifice so that it is inwardly concave when the container is in an undeformed condition. The concave shaped portion of the valve includes at least one substantially linear slit extending through the thickness of the valve. The valve requires the attainment of a threshold opening pressure to effect inversion from a concave at rest position in order to dispense the package contents. By providing a container with sufficient flexibility to permit manual deformation and sufficient resilience to return substantially to its undeformed configuration when the externally applied forces are removed, a void volume equivalent to the amount of fluid material discharged from the package is provided inside the container after removal of the applied forces. This aids in closing the self-sealing valve which, after venting the container to the atmosphere, returns to an inwardly concave, sealed position until sufficiently large external forces are again applied to the container to effect inversion of the valve and consequent material discharge.
