A dust collector (30) is accommodated in the nozzle housings and defines in it a second air passage (36) communicating the first air passage. A thread catcher (30) is so accommodated in the dust collector as to be rotatable in response to forward and rearward movement of the floor nozzle. The thread catcher is capable of catch waste thread on a surface to be cleaned when it rotates upon forward movement of the floor nozzle. A scraper (32) is accommodated in the dust collector for removing the waste thread caught by the thread catcher when the thread catcher rotates upon rearward movement of the floor nozzle. A covering member (38) is hingedly connected to the dust collector for opening or closing the second air passage.

Abstract: An elevated back-lit display providing easy replacement of light sources and great uniformity of light distribution. A light source in a support column emits light into a light conduit also in the support column. Light is conducted through the light conduit to an optical cavity with an optical window. Light entering the optical cavity from the light conduit is dispersed throughout the optical cavity by a beam spreader. Total internal reflection film in said optical window helps to improve the uniformity of light distribution in the optical cavity.

Abstract: A power steering system suitable for large off-highway and other vehicles has no mechanical linkages or hydraulic connections entering into the driver's cab. Torque demand signals are produced in an electromechanical torque sensor (TQS) that measures the deflections of a torsional spring (TLS). The system provides synchronization between steering wheel (SGW) and steered wheels (SDW) upon starting, without initial corrective motion of either member. During operation, the direction of the steered wheels does not drift with respect to the position of the steering wheel. In the event of certain types of failures of its primary steering system the apparatus automatically changes over to an open-loop secondary steering system that is controllable by the same steering wheel, and that has components (DCM, HP, etc.) in common with the closed-loop primary system.

Abstract: In a picture-quality improving circuit, a luminance transition is detected on the basis of a luminance signal. Chroma edge characteristics of a color signal are enhanced in accordance with the detected luminance transition. A detection is made as to whether the color signal and the luminance signal are correlated or uncorrelated in transition. When the color signal and the luminance signal are uncorrelated in transition, the enhancement of the chroma edge characteristics of the color signal is interrupted.

Abstract: A water-insoluble microporous article comprises a microporous substrate having first and second outer surfaces. Affixed to at least one of those surfaces is a stabilized specific binding reagent admixed with certain hydrophilic, neutral or positively-charged binder materials. Particularly useful binder materials include certain quaternary polymers, vinylpyrrolidone polymers and acrylamide polymers. In this mixture, the reagent exhibits improved keeping stability compared to similar reagents used without binder materials. The reagent comprises water-insoluble particles to which are attached receptor molecules to a target ligand. Substantially none of the reagent is entrapped within the microporous substrate. This article is useful for the detection of a target ligand in an assay involving the specific binding reaction of the ligand with corresponding receptor molecules, and can be included in a diagnostic test kit. It is particularly useful for the detection of Streptococcal antigen in a biological specimen when the receptor molecules are antibodies to that antigen.

Abstract: A hybrid nonwoven liner for a diskette holder is bonded and impregnated with a small amount of binder which is uniformly distributed throughout the fabric and comprises no more then five (5) percent by weight and preferably between 1.5 - 3.0% by weight of the fabric. The low concentration of binder ensures that the liner surface does not become totally coated with a plastic film that reduces cleaning ability, while also providing a high increase in tensile strength and a significant debris reduction. The binder solution preferably has a high surface tension (low surfactant level), so that the binder beads and becomes dried at junction points of the fibers and evenly distributed throughout the fabric. The low level of surfactant ensures a low risk of chemical attack of the disk media surface.

Abstract: The frame (31) for letterboxes (30) which have a cube-shaped cavity encompasses the cavity on the peripheral sides. At the front and back sides, the cavity is closed either by a removal door in each case or by one removal door and one fixed closing wall. The frame has four straight frame parts (40 ... 43), connected to each other by one edge part (45) in each case. These edge parts (45) are composed of one edge piece and two corner pieces, the edge piece having a cylindrical surface shell and the corner pieces an outer surface which is designed as a section of a toroidal surface. The corner pieces have dowels on the connecting surfaces which are matched to recesses in the edge pieces and, in some cases, in the frame parts. The frame parts (40 ... 43) may have a rounded oblong cross-sectional shape and be of hollow design. In this case they have recesses in their interior for receiving the dowels of the corner pieces and of the edge pieces. The corner pieces and edge pieces are, moreover, provided on the connecting surfaces with groove-shaped recesses into which flat panels can be inserted which serve instead of hollow profiles as frame parts.

Abstract: A composite stream, having a higher content of a high-boiling component than a working stream, is used to provide heat needed to partially evaporate the working stream. After being partially evaporated (heat exchanger 214), the working stream is evaporated completely with heat provided by returning gaseous working streams (heat exchangers 251,252) and heat from an auxiliary steam cycle (heat exchanger 250). After being superheated (heater 201), the working stream is expanded in a turbine (202). Thereafter, the expanded stream is separated (separator 231) into a spent stream and a withdrawal stream. The withdrawal stream is combined (at 241) with a lean stream to produce the composite stream. The composite stream (in heat exchanger 212) partially evaporates the working stream and preheats the working stream and the lean stream. A first portion of the composite stream is fed into a distillation tower (225). A liquid stream flowing from the distillation tower (225) forms the lean stream that is combined with the withdrawal steam. A vapor stream flowing from the distillation tower (225) combines (at 246) with a second portion of the composite stream to produce a pre-condensed working stream that is condensed (condenser 221) forming a liquid working stream. The cycle is complete when the liquid working stream is preheated (heat exchangers 228,217) prior to being partially evaporated.

Abstract: A die spool (10) for the extrusion of thermoplastic materials includes an axially split elongate spool body so as to be separable into first and second spool segments. The spool segments collectively establish the spool body and also define an axially oriented extrusion cavity through which thermoplastic material is conveyed. An alignment system ensures that only a single orientation of the extrusion axis is possible when the die spool is coupled to another similar die spool (or to an extrusion die associated with an extruder). A die spool assembly (10) may therefore be provided which is comprised of a number of individual die spools (10a,10b,10c). Preferably, a decreasing temperature gradient is established within the extrusion cavity of the die spool assembly (10) (as may be accomplished by controllably operating electrical resistive heater elements) so as to at least partially solidify the thermoplastic extrudate therewithin. During extrusion start-up, a lower die spool segment (36a,36b,36c) is employed to support an initial length of thermoplastic extrudate, with the upper die spool segment (34a,34b,34c) being mated therewith (thereby collectively defining the extrusion cavity) once the extrudate extends beyond the downstream end of the lower segment. In such a manner, manual conveyance assistance along the extrusion axis may be imparted to the extrudate during start-up.
