Abstract: A multi-layer paper machine wire includes an upper fabric layer, a lower fabric layer and an additional layer disposed between the upper and lower fabric layers. The additional layer includes weft threads that alternate with binding threads. Warp threads of the upper fabric layer run over the weft threads of the additional layer and are interwoven with binding threads of the additional layer. Likewise, weft threads of the lower fabric layer run below the weft threads of the additional layer and are interwoven with binding threads of the additional layer.

Abstract: A braided ribbon fabrication method including the steps of (1) installing a disk-like thread guide in a ribbon braiding machine, the disk-like thread guide having a center through hole and a plurality of thread holes equiangularly spaced around the center through hole, (2) inserting a cord member through the center through hole of the disk-like thread guide and alternatively inserting different thickness of threads through the thread holes of the disk-like thread guide, (3) braiding the cord member and the threads into a braided ribbon, enabling the braided ribbon to be extended out of an output barrel, and (4) applying a rotary external force to the braided ribbon that extends out of the output barrel during braiding, so as to produce a pattern of a braided stripe in the finished braided ribbon.

Abstract: A sewing machine for making edge-parallel shaping seams in multiple layer articles such as shirt collars comprises a reciprocating needle for sewing through the multiple layers of a workpiece such as a collar which has a plurality of edges disposed at angles to each other. The construction includes a guide fence having a guide edge extending alongside the needle. The material is guided against the guide edge. A feeder engages the workpiece from below a presser foot which is biased against the needle in a working position. The presser foot has an upwardly extending infeed end and a holddown member in the form of a strip element. It is adjustably supported above the workpiece and includes a front edge which is engaged downwardly on the workpiece and extends into the infeed end of the presser foot.

Abstract: An articulated hinge for pivotally connecting a door flap to the carcass of a piece of furniture which has spaced carcass walls and a frame facing the door and extending essentially at right angles to the carcass walls and confining a free door opening, while the door flap in closed position partially overlaps the frame. The hinge has a carcass-related part connected to the edge surface of the frame offset inwardly relative to the adjacent carcass wall, and a door-related part connected to the door flap and pivotally connected to the carcass-related part via a link mechanism. The door-related part is in the form of an insert cup with a connecting part fittingly inserted into a recess in the backside of the door flap, and a link carrier part which has a portion interlocking with the connecting part.

Abstract: An impact member for driven flywheel impact devices, such as nailers and staplers, is disclosed which may be configured to tailor the normal force as a function of ram position. A basic configuration is a constant taper, which, as soon as the impact member is actuated by a flywheel, assists in maintaining driving friction on the impact member. The taper may be linear, stepped or curved, and symmetric or asymmetric about the longitudinal axis of the ram, whereby to tailor the impact member speed for different purposes.

Abstract: A method for interlacing or entangling continuous multifilament synthetic yarn wherein the yarn to be interlaced is fed along a feed path through a yarn feed bore to a jet nozzle member defining with a surrounding housing and an outlet tube member a shaped turbulence chamber within the housing at the exit of the yarn feed bore in the nozzle member. The jet nozzle member has one or more jet passages directing fluid from a pressurized air chamber into the turbulence chamber along jet axes inclined to the yarn feed axis and offset sidewise in non-intersecting relation thereto to produce interlocking entanglements of filaments of the yarn during passage therethrough.

Abstract: A toner density controller for determining the density of a development material in a magnetic brush assembly of an electrostatic copier is disclosed. Means is provided for imposing a charge on the toner density controller which is opposite in charge to that of the toner particles of the development material. In this way, the toner particles, particularly fines, are repelled from the toner density controller to eliminate interference with the functioning of the controller.
