Abstract: A generally cylindrical opening roller unit of an open-end spinning device includes a unitary ring body having card clothing formed of at least one helical groove formed in the ring body, at least one helical ridge between courses of the groove, and saw teeth defined by transverse cuts on the ridge. The roller unit also includes an integrated annular collar that is at least codiametric with the teeth in order to protect the teeth. An integral transition area between the card clothing and the annular collars eliminates the problem of a tooth gap.

Abstract: A method and device for restarting a spinning operation at work stations (2) of an open-end spinning machine (1) after replacement of a cheese (8) with an empty tube by a traveling service unit (16) comprising an auxiliary yarn supply device (21). Each work station comprises a yarn spinning device (3) and a cheese winding device (4) with a creel (9). The auxiliary yarn supply device (21) delivers a starting portion of an auxiliary yarn (24) to a suction nozzle (14), which transfers the auxiliary yarn (24) to a spinning start member (20), after which the suction nozzle (14) pivots to re-take the auxiliary yarn (24) between the supply device (21) and the spinning start member (20) and removes the auxiliary yarn (24) after restarting the spinning operation, whereupon the yarn (7) is brought to the creel (9) of the work station (2).

The coupling device (29) comprises a magnetic device (30) for fixing rotor shaft (4) and rotor cup (26) axially relative to one another and a mechanical rotational safety mechanism (31) for fixing rotor shaft (4) and rotor cup (26) radially relative to one another.

Abstract: A glider chair in a recreational vehicle including a frame suspended from a base by a gliding mechanism for movement of the frame in a horizontal back-and-forth gliding motion relative to the base and a locking mechanism selectively operable to disable the gliding motion of the chair relative to the base. The locking mechanism has a locking plate mounted on a rotatable arm secured in a base from the chair to move pivotally between an inactive position wherein the plate is spaced from the suspended portion of the glider mechanism and a locking position where the plate engages a frame member of the suspended portion of the glider mechanism to prevent horizontal back-and-forth motion of the frame member relative to the base.

Abstract: A coater for applying foamed coating material to a traveling textile substrate including a frame, a flush pan, an applicator having an open slot, a pivot shaft journaled in a pair of support arms that are pivotally mounted to the frame and piston-cylinder mechanisms to move the applicator between an operating position wherein the open slot is adjacent the traveling substrate and a flush position wherein the open slot is adjacent the flush pan by pivoting the support arms and rotating the pivot shaft. Foamed coating material is applied by supporting the traveling substrate between two spaced support elements, contacting the traveling substrate with a foam applicator, and forcing a metered amount of foamed material at least partially into the interstices of the textile substrate before the foamed coating material collapses. A metered amount of foamed coating material is applied onto or into a textile substrate regardless of textile substrate structure and regardless of the viscosity of the coating material.

The metallized laminate is made from a plurality of discontinuous metal island layers deposited on a formable clear coat film. The invention is also a method that includes depositing a first discontinuous layer of metal islands upon a formable clear coat film and then depositing a second discontinuous layer of metal islands onto the first discontinuous layer of metal islands.

Abstract: Systems and methods for displaying food information to a user, involving assigning each of a plurality of remote sensor units to a designated food receptacle containing food, categorizing each food receptacle into one of a plurality of food receptacle types, and displaying, in a central location, an indication of the type of food receptacle to which the remote sensor unit is assigned and an indication of the food stored therein.

Abstract: A method and apparatus for the descaling of metal surfaces without the use of caustic substances is provided. The apparatus includes a first and second blast heads containing fan shaped nozzles that spray high velocity jets of smooth edged, ceramic media at a scale covered continuous sheet of steel. The continuous sheet of steel is advanced into an abrading station containing a pair of brush assemblies that include stainless steel bristled brushes. The stainless steel brushes engage the surface of the sheet of steel and abrade away the cracked scale, leaving a surface clean of scale. The surface produced is pH neutral and therefore resists additional corrosion and does not require oil coatings, or other protective treatments. The metal surface is produced with a roughness that is less than 2.5 microns Ra without stretching, polishing, cold-rolling or the use of acid pickling. Eliminating these steps makes for a faster, more robust process and saves considerable cost.

Abstract: Systems and methods are provided for gathering temperature and other food condition information at a plurality of remote sensor units and transmitting it to a central collection location. Data may be buffered at each sensor unit until communications have been established between the unit and the central computer. A plurality of interface units may be provided for receiving data from the sensor units and relaying it to the central computer. At the central computer, the data may be compared to a preset limit, and if the limit is violated, an alarm may be generated at the corresponding remote sensor unit. If a deactivation request is received at a sensor unit, then a signal is transmitted to the central computer to warn of the deactivation, and the sensor unit is deactivated.

Abstract: A warp knitted textile fabric and a method of producing such a fabric, characterized by a resiliently stretchable three-bar stitch construction, one fabric surface of which presents outwardly extending knitted loops adapted to serve as the loop component in a hook-and-loop fastener system. The fabric is knitted on a warp knitting machine by interknitting ground, elastic and loop-forming yarns together in knitted stitches on spaced needles in spaced fabric courses and interknitting stitches of the ground and elastic yarns on the same spaced needles in intervening courses while forming loops of the loop-forning yarns on inactive intervening needles to be cast off without integration into the ground structure of the fabric so as to form outwardly extending pile loops on one fabric surface. The pile loops do not require brushing or napping to render the fabric suitable for use in a hook-and-loop fastener system.

Abstract: An opening arrangement for an open-end spinning device with a rotating opening roller having opening elements stationarily arranged on its circumference for opening a delivered sliver into individual fibers and for combing out the fibers at a comb-out point. The opening roller has a mechanical stripping arrangement that rotates along with it. The stripping arrangement includes ejectors that are pivotably fastened on the opening roller. Each ejector is arranged between the opening elements and extends over the opening roller transversely in relation to the direction of rotation. The ejector strips combed-out fibers off the opening elements and improves the opening of the opening roller as well as the transfer of the fibers from the opening roller. The opening arrangement is advantageously employed with an open-end spinning frame.
