Abstract: An apparatus for color coding and dyeing or otherwise marking a light wave conductor optical fiber includes a dyeing stage and a drying stage; the conductor is unreeled from a spool for passing through the stages, the marked conductor is taken up by another spool or the like, and a downstream drive is coupled to the conductor for moving it at a particular speed through the dyeing and drying stages. An upstream drive mechanism is also coupled to the conductor upstream from the dyeing stage for pulling the same from the supply spool, and includes a drive controlled towards the same speed as the downstream drive and a compensating roller to ensure sufficient tension in the conductor so that the upstream and downstream speeds are similar.

Abstract: A single gas analyzer is used for analyzing the concentration of two gaseous components such as hydrogen and chlorine in a blend by responding to the chlorine content in the gas blend there being a UV-type reactor for the formation of hydrochloric acid and the operation is such that the gas to be analyzed alternates between a path in which the reaction has taken place and one in which such a reaction has not taken place, for directly measuring the concentration of the gas with a higher concentration and indirectly the concentration of the gas with the lower concentration by determining the depletion the reaction has caused in the higher concentration gas.

Abstract: The rotor is held on a shaft by means of a membrane providing an easy resilient deflection in axial direction and being stiff for torque transmission in azimuthal direction. The membrane is star-shaped, or has spiral arms or is of polygonal configuration. A membrane carrier is connected to a central part of the membrane or to polygon corner points; the rotor, through a sleeve extension of a short circuiting ring is connected to peripheral points of the membrane. The carrier is splined to or slip friction coupled to the shaft.

Abstract: A disassemblable chair constructed of three corrugated paper board elements brought together and interlocked by slotting in each of the elements. The first and basic element may be die cut from a rectangular corrugated board sheet which is creased, bent over and secured along overlapping edges to form a rectangular cross sectional seat and back support. A second rectangular slotted element is disposed transversely across the seat supporting edges of the first element to complete the seat support; and a third rectangular element is laid over the seat and back support and secured by insertion of its end and a center fold into interlocking slotting in the first element.

Abstract: An improvement to a tubular height adjustable crutch of the type having a foot telescopically slidable within a carrier tube supported between the parallel lower ends of two crutch bows, where the crutch bow ends are right cylinders cut so as to form a right angle corner with the footpiece or carrier tube. A unitary end cap is fitted over the bow ends and the carrier tube for retaining these three members together and to provide an integral bushing for supporting the footpiece against wobbling within the carrier tube. The improvement consists of modifying the cap bottom to provide slanting edges or surfaces for deflecting staircase edges away from possible engagement with the corner defined between the bow ends and the carrier tube, thus preventing consequent injury to the crutch user.

Abstract: A matrix printer normally cooperates with a particular character generator by means of which coded information representing characters to be printed is translated into a matrix of print commands for print styli printing dots out of which a character is composed. In accordance with the invention, the same character generator is used for printing smaller characters in superscript, subscript or in formal footnotes, by using a particular algorithm to translate the generator information into different set of information for each character, so as to reassign print commands for the several print styli.

Abstract: A telescopic, length extensible device, having a plurality of telescoping hollow elements, including an innermost one, at least one further, and an outermost one, further indluded a drive connected for obtaining telescopic extension and retaction is improved by a device for ensuring a predetermined sequence in the extension and retraction of the element comprising a first pin mounted for radial displacement, on one of any two mutually adjacent ones of the elements, the first pin having slot means, and being provided for selective insertion into and retraction from a third one of the elements; a couter latch element for latching insertion under spring bias and connected to another one of the two elements, such that when latching obtains, the first pin is retracted from the third element; a second spring-biased pin has a nose for lateral engagement with notches in the first pin and a control lever, operates in response to positions of the third element for locking and unlocking the second pin so that the second

Abstract: A cat litter box system including a tray which may have inwardly canted edges and a waterproof bottom. Inserted in the tray is at least one orificed filter sheet, and prefereably several, having some type of corner or edge lifting means. Also desirably provided is a filter protector comprising a mat having upward extending protrusions disposed in register with the filter sheet orifices to pass through the latter and protect the filter sheets from damage by the clawing of the cat through litter material which is deposited in the tray over the filter sheets and the filter protector, where the latter is also used. Deodorizing strips, capsules and/or filter protector tips may also be provided.

Abstract: A removable pump assembly for use in a cryogenic storage tank pumps liquid cryogen directly from the primary storage container with low boiloff loss. The cryogenic storage tank has an outer vessel, an inner vessel, an evacuated insulation space therebetween and a access port connecting the inner and outer vessels and providing an open cylindrical access to the interior of the cryogenic tank. A pump mounting tube assembly is disposed into the interior of the inner vessel of the cryogenic tank through the access port and includes an inner pump mounting tube and an outer pump mounting tube which are joined at their upper and lower rims to define an insulating jacket between the two tubes. The inner and outer pump mounting tubes are affixed at their upper ends to a top and bottom plate. The top and bottom plate in turn is affixed to an insulating block. Only the insulating block, which is disposed in the access port of the cryogenic tube, is in contact with any portion of the cryogenic tank.
