Abstract: NETWORK ROUTING AND CONTROL ARRANGEMENT            Abstract of the Disclosure A system is disclosed for selecting and establishing connections through a two-stage concentrator network utilizing path selection circuitry adapted to minimize blocking.  This circuitry operates to select a path through the second-stage switch which is the least congested (i.e., has the most idle output lines).  More specifically, "congestion" information is generated from "outlet" information specifying the idle/busy status of the outlets or terminals of the second-stage switches.  This congestion information is logically combined with link information, specifying the idle/busy status of link paths interconnecting the stages, to ascertain if a path is available through one of the least congested second-stage switches.  If a path is available, an idle outlet is selected on a least-congested second-stage switch, and then a connection is completed to the selected idle outlet.

Abstract: ABSTRACT OF THE DISCLOSURE          This relates to methods and apparatus for filtering liquids such as oil contaminated water.  The apparatus includes spaced apart supply and take-up reels capable of storing an elongated compressed ribbon of flexible open cell foam thereon.          In operation the ribbon of filtering medium, in the uncompressed state, extends between the supply and take-up means across a support such as a grid or screen which permits free flow of water through the filter medium.  The contaminated water is supplied to the upper side of an exposed section of the filter medium through a system  which evenly distributes the contaminated water over the exposed section of the filter medium.  The water passing through the filter medium may be collected in a suitable tank or basin.  When the exposed section of filter medium becomes so loaded with contaminants (such as oil) that the flow through the filter decreases, the ribbon is advanced to expose a fresh section.  Means are provided for compressing the contaminated ribbon to extract contaminants therefrom before it is wound up on the take-up means.  The recovered oil is directed to a receptacle.  Both the supply and take-up means are provided with compression means which assist in compressing the ribbon of filter medium and maintaining same in the compressed state thereby contributing greatly to the compactness of the overall system.

Abstract: ZOOM LENS COPIER                   ABSTRACT OF THE DISCLOSURE          An imaging lens system for electrostatic type reproduction machine or copiers utilizing a zoom lens effec-tive to provide, within the magnification limits of the lens, infinitely variable image sizes.  A control is provided to pre-set the lens to automatically give, upon actuation, at least one preselected image size, with an override control to enable the lens to be set to provide any image size regardless of pre-set conditions.  Further controls are provided for the machine non-image erase mechanism to auto-matically compensate for changes in the image borders brought about by changes in image size due to resetting of the zoom lens.  For this purpose, an infinitely variable edge fadeout apparatus is provided incorporating movable shutters to vary the effective size of the edge erasure slots in correspondence with image size together with timing controls for changing the operational timing of the pitch fadeout lamp in response to changes in image size upon resetting of the zoom lens.  Further controls enable the critical positioning of the image produced by the zoom lens on the photosensitive member to be adjusted to assure that the image, whatever the size, is optimally positioned on the copy produced with other controls to enable the image, whatever the size produced by the zoom lens, to be physically moved or offset on the copy.

Abstract: L'épuration oxydante des eaux est réalisée par l'emploie comme agent oxydant d'oxygène obtenu dans l'état excité dit singulet.  L'oxygène singulet peut être préparé par l'action du peroxyde d'hydrogène sur de l'hypochlorite de sodium ou sur du brome.  Le procédé  de l'invention s'applique notamment au traitement des effluents industriels contenant des corps toxiques tels que les cyanures, les cyanhydrines et les phénols, ainsi que des eaux brutes chargées en matières organiques.  Du fait de la grande activité de l'oxygène singulet, il n'est généralement pas nécessaire d'ajouter un excès important d'oxydant pour obtenir une destruction complète des produits toxiques.  Dans le cas des cyanures, un excès d'oxygène singulet de 20 à 40% par rapport à la stoechiométrie est généralement suffisant, ce qui montre la supériorité de ce traitement sur les traitements connus.  Pour les effluents contenant des cyanhydrines, le rapport              doit généralement être compris entre 2 et 3, et dans le cas des phénols, le rapport molaire varie avec la concentration en phénol et doit être généralement compris entre 4 et 10 pour le phénol C6H5OH.

The method couples a discharge pipe to the ferrule structure with a compressible sleeve which extends over facing ends of the discharge pipe and ferrule.  Ring clamps compress and seal the sleeve to the discharge pipe and ferrule structure. Ears project from a flange attached to one end of the discharge pipe at a floor which supports the toilet for supporting the discharge pipe from the floor.  A nipple may be inserted into the discharge pipe for attaching another pipe intermediate ends of the discharge pipe.  A shield extends about the nipple and conforms to the outside of the discharge pipe to aid in adhesively sealing the nipple to the discharge pipe.

Abstract: ABSTRACT OF THE DISCLOSURE           For examining a body by means of X-rays or other penetrating radiation, data is determined representing the absorption suffered by each of a plurality of beams which are passed through the body.   The beams are effectively arranged in a plurality of sets of beams, in a single plane, at many different angles.   The arrangement is such that the amount of information provided by the beams is a function, which is in part non-uniform, of the beam position in the set.   A reconstruction of the distribution of absorption of the radiation within a part of the body is derived from the absorption data so determined.

Abstract: ABSTRACT OF THE DISCLOSURE A screening device suitable for cleaning railroad ballast which has become fouled with use, and of the type in which ballast to be cleaned is fed into a screen member to separate the coarse or ballast stone from the fines, the stone being reused to ballast the track.  A screen member of generally frusto-conical shape, open at each end, is rotatably mounted on a track running frame, with the axis of the screen extending substantially parallel to the track and either horizontal or slightly inclined to the horizontal.  The screen member is rotated so that centrifugal action results in the fouled ballast, loaded into the narrower open end of the screen member, moving up the walls thereof to its larger open end.  The fines pass through the screen member and the stone is collected at a stone receiving member located adjacent the wide end of the screen member.  A generally frusto-conical fines receiving member of larger diameter than the screen member partially surrounds the screen member and receives the fines which fall therethrough.  Conveying members are provided to convey the fines from the fines receiving member to a point of disposal, whilst the stones received by the stone receiving member are delivered back for re-distribution on the track.

Abstract: ABSTRACT OF THE DISCLOSURE         Space interchange of PCM words are carried out by means of a circulating shift register.  The PCM words are transmitted on a number of incoming and outgoing links during time slots according to a time division multiplex system.  At the beginning of their allotted time slots, the incoming PCM words are registered each in an associated shift register stage.          The circulating shift register is clocked sufficiently fast for each PCM word to pass through all shift register stages during the respective time slot.  By means of control words each associated with one of the time slots and with one of the outgoing links is determined during which clock pulse said outgoing link is connected to the output of its associated shift register stage.  A buffer memory is arranged between the circulating shift register and the outgoing links in order to re-establish the correct time division multiplex system for the outgoint PCM-words.
