Abstract: After yarn breakage, yarn loops are formed in an accumulator device (3) by rollers (13, 13') that are able to be displaced in relation to each other. The beam is rotated in reverse at a specific reverse speed (c) which is less than the accumulation speed of the accumulator rollers (13, 13'). The length difference arising from the difference between both the speeds is compensated by further withdrawal of yarns (a) from the creel (1) while the yarns are subjected to a defined braking tension of the individual yarn tensioners (7). Complex controls and speed synchronization are thus avoided.

Abstract: The textile web (1) is guided through a relatively narrow shaft the limits of which are formed at least partially by the surface of rollers (2, 3). Nozzles (7), from which a treatment medium can be applied onto the textile web, are arranged in the curved sections (6, 6') of the shaft. Straight sections (8) between the rollers can be kept very short. The device is especially suitable for the treatment of tension-sensitive textile webs.

Abstract: A height adjustable stand for laboratory equipment, in particular for rotary evaporators, possesses a holder arrangement (6). The holder arrangement is able to be displaced vertically on a stand post (5). By way of a motor driven lifting arrangement (9, 11), the holder device (6) can be vertically raised or lowered. A coupling (12) is provided between the holder arrangement (6) and the lifting arrangement (9, 11) for the powered connection and its release.

Abstract: A breathing circuit apparatus used with a nebulizer device that generates an aerosol is adapted for use by a user for inhaling the aerosol through the user's nose and/or mouth and thereafter exhaling exhalation gas through the breathing circuit apparatus. The breathing circuit apparatus includes a container, an inlet valve, an outlet valve and a user connection port. The container defines an interior chamber therein and is coupled to the nebulizer device. The inlet valve is connected to the container and includes an air inlet port for one-way air flow of ambient air into the interior chamber. The inlet valve moves between a closed condition to prevent the ambient air from entering into the interior chamber and an opened condition to permit the ambient air to enter into the interior chamber. The outlet valve is connected to the container and includes a gas exhalation port for one-way gas flow of the exhalation gas.

Abstract: A freeze-resistant downspout system includes a metal downspout having an interior portion within a building and a contiguous exterior portion outside the building. The exterior portion is shielded from the weather by a thermally insulated shroud so that heat conducted along the downspout from within the building is sufficient to keep the exterior portion from freezing.

Abstract: A monocentric seamless bifocal lens is manufactured by obtaining a lens blank having concentric top and bottom spherical surfaces, and grinding the bottom surface to form a major segment having one spherical radius and a minor segment having a second spherical radius. The lens is then placed on a block having two spherical surface portions whose shape conforms to the shape of the major segment, but differs from the shape of the minor segment. The block also has a slight dihedral angle, so that a space remains between the block and at least part of the minor segment. As it rests on the block, the lens is heated so that it sags under its own weight until its bottom surface assumes the shape of the block, and the radius of curvature of the upper surface becomes non-uniform. Finally the bottom surface of the lens is ground and polished to a uniform spherical radius.

Abstract: With a device for reducing in size and mixing material (4), a blade (12) rotates in a the working chamber (2) of a container (3). During reducing in size and mixing, the working chamber (2) is reduced in volume by means of a piston.

Abstract: Soluble zirconium and hafnium organic acid complexes are made by forming an aqueous mixture of a basic carbonate of either zirconium or hafnium and the organic acid such a propionic acid. The molar ratio of the organic acid to metal in the carbonate is greater than about 1.5. The mixture is heated with stirring to form the complex which is then recovered as a dry, free-flowing powder.

Abstract: An impact element (12, 17), which is connected with a spring device (15), is tensioned through the feed movement of the package carrier rods (5) and, when a trigger position (23) is reached, will be released in such a way that a force impulse (I) is delivered in the direction of the nearest adjacent spindle (6), respectively a remnant package (2) or empty bobbin (3) mounted on said spindle. With that, the impact element transmits a force impulse, first of all onto a lossely mounted impact disc (19) which can be utilised with various bobbin formats and which protects the remnant packages.

Abstract: A tubing end-piece interconnects a free end of a piece of tubing and a tubing connector or fitting so that a fluid can flow between the tubing and the fitting or connector. The tubing end-piece includes a body member extending along a longitudinal axis with a bore extending longitudinally therethrough. The body member has an elongated body portion, a doughnut-shaped head portion and a frustoconically-shaped tail portion. The body portion has an outer body surface configured in a shape of a frustum that tapers from a first end and towards a second end. The doughnut-shaped head portion is connected to the first end of said body portion and extends radially outwardly relative to the longitudinal axis to form in cross-section an outer curved surface commencing from the first end and terminating in an outer peripheral edge which defines a first opening into the bore.

Abstract: An improved carbochlorination process for the production of volatile metal chlorides is disclosed. When chlorine gas contacts a metal oxide or a mixed metal oxide in a reaction zone in the presence of carbon at elevated temperatures, an undesirable carbochlorination residue forms containing carbon in the reaction zone. After the build-up of a carbochlorination residue in the reaction zone occurs, the volume of the carbochlorination residue in the reaction zone is reduced by periodically introducing just chlorine and metal oxide or mixed metal oxide reactants into the reaction zone without introducing any additional carbon. These components react with a portion of the carbon in the carbochlorination residue so as to reduce the amount of the residue.

Abstract: An apparatus for cutting wings from boned whole poultry breasts includes a pair of spaced chain loops supporting laterally aligned pairs of fixtures which hold the wings to support the breasts and serve as anvils for annular knife blades which are driven outward from a central position to cut the breasts from the wings. Thereafter, the wings remain secured in the fixtures, while first the tips are removed by a guillotine-type cutter, and then the flat wing segment is folded against the drumette before the elbow joint is cut.

Abstract: An ignition system for igniting fuel within an engine, comprising at least one ignition plug disposed in the engine, wherein the ignition plug has a pair of electrodes. A high voltage generator is connected to the ignition plug for applying a gated high voltage high frequency AC signal across the pair of electrodes so as to initiate ionization of the air/fuel mixture and create an infant plasma channel between the pair of electrodes. A plasma arc current generator is connected to the ignition plug for generating a predetermined magnitude of alternating current for a predetermined period of time so as to sustain the plasma channel and ignite the fuel, and a controller is provided for selectively enabling and disabling the high voltage generator and the plasma arc current generator at predetermined times.

Abstract: The material web (1) is acted upon by heated circulating air which permeates with the aid of a fan (7) from a pressure chamber (14) via inlets (6, 6') into the nozzle casings (4, 4'). In order to achieve laminar flow and thus an improved distribution of air, the fan (7) is removed as far as possible from the inlets (6, 6') and preferably suspended beneath the cover-wall (16) of the housing (2). This results in a relatively large and longitudinally extended pressure chamber (14) between the inlets (6, 6') and the pressure side (12) of the fan (7).

Abstract: Mechanical energy is supplied to an implement on a rotating spindle, and a generator on the implement converts the mechanical energy into electric power. Preferably the energy is supplied in the form of rotary motion via the work spindle. Alternatively, a fluent medium, for example, coolant or compressed air, can be supplied, in which case the medium is used to drive a turbine wheel coupled to the generator.

Abstract: A control device which may take the form of a plug adaptor is able to interrupt the power to a dryer when the load is dry. The only input is the pattern of the power consumption of the dryer, and this is used, together with a control algorithm, to provide the information needed for the control decision. The device, which provides a superior process for determining the cycle termination point, could also be incorporated directly into the dryers at the point of manufacture. In addition, the invention can correlate the moisture level and character of the laundry load with the pattern of power consumption of the clothes dryer. This correlation may be used to further optimize the performance of the drying cycle or to provide load-specific control and termination procedures.

Abstract: A method and apparatus for transmitting print data signals serially to a printing device is disclosed. Print data for printing dots selectively line by line is stored as a plurality of bytes in which each byte represents the number of contiguous binary bits to be output to the printing device having the same binary value. The bytes are output to a comparator which receives the output of a counter driven by clock signals. The counter is started when a byte is output and the clock signals clock a data line held at a level representing the value of the bits. When the count equals the byte, the comparator toggles the data line so that it is at a level representing the next binary bits to be output. The apparatus is disclosed for use in a franking machine.

Abstract: A laminating press for wood products includes at least one pair of heated drums rotating on parallel axes and an endless belt running around the drums, and a device for pressing a stack of materials to be laminated against the belt between the drums, wherein the belt consists essentially of a zirconium or titanium alloy having a thermal diffusivity of at least 0.08 cm.sup.2 /sec and Young's modulus below 20 million psi. Unplated, the belt material provides a non-stick surface with respect to melamine, and because it is unplated, the belt can be resurfaced when worn. Alternatively, the above materials are used in constructing plates for a platen-type laminating press.
