Granted: 1991-05-14
Abstract: ABSTRACT OF THE DISCLOSURE       A multi-layer  fabric  for  paper-making comprising  at least two fabric layers A and B, each of which is formed by inter-weaving respective warps and wefts.  An upper-most layer A is woven as a plain weave 1/1 except at binding points S1, S3 and is adapted to support a paper-web thereon.  A lower layer B is positioned below the upper-most layer A, and formed by warps 3 and wefts 4, 4a, each of which have larger diameters than those of the upper-most layer A.  The upper-most layer A and the lower-most layer B are bound by means of a part 1a of the warps 1 of the upper-most layer A being intermoven with a part 4a of the wefts 4 of the lower-most layer, or by means of separate binder threads 5 other than the warps or wefts being interwoven  with  the  upper-most  layer  A  and  the  lower-most layer B. At the binding points, a warp 1a of the upper-most layer which intersects with a weft 4a of the lower-most layer B or with a binder thread 5 is extended under three successive wefts 2a.  A weft 2a of the upper-most layer A at the binding point S1 is extended above three successive warps 1, 1a, 1 of the upper-most layer A.

Title: Method and apparatus for determining the distance of an object
Inventor: FRANKLIN DOUGLAS E
IPC: G01S13/42
Filed: 1988-02-05
Granted: 1991-05-07
Abstract: ABSTRACT OF THE DISCLOSURE         The present invention provides a method and apparatus to determine the position, velocity and orien-tation of an object with respect to an observation point.          It consists of placing a sensor spaced from the object and placed at the observation point which will emit two non-parallel beams of light toward the object.          Retroreflectors on the object will reflect the light in opposite direction to generate pulses of reflected light caused by the angular relative motion between the inci-dent beam of light and the retroreflectors.  A processor can be used to provide an indication of the position, velocity and orientation of the object based on the time interval between reflected pulses.

Granted: 1995-08-08
Abstract: A web travelling through a twin-wire cylinder drier of a paper machine is subjected to a suction effect as it separates from a drying cylinder within a negative pressure zone provided at a region of its run at which it is in contact with the drying wire so that the length of the open draw of the web is substantially reduced.  The negative pressure zone is produced by a gas jet which is directed through an oblong passage defined by the outer surface of the drying wire situated on the drying cylinder and by the surface of a wall of a blow box.  By directing the gas jet through the oblong passage, the boundary-layer flow following the drying wire is substantially reversed in direction to flow in a direction opposite to the run of the drying wire to thereby produce a negative pressure space at the rear side of the passage.

Title: Windshield washer/wiper apparatus
Inventor: PONZIANI RICHARD L
IPC: B60S1/48
Filed: 1988-08-23
Granted: 1993-03-16
Abstract: WINDSHIELD WASHER/WIPER APPARATUS   Abstract of the Disclosure In a vehicle windshield washer and wiper apparatus, the closure of a washer switch activates the washer and wiper and charges a capacitor to a first voltage.  When the washer switch is released, the washer is deactivated but the wiper is activated through several more wipe cycles while the capacitor is discharging to a second voltage.  The final wipe cycle and wiper parking is to be controlled by a wiper position responsive switch which is closed throughout the wipe pattern except for a predetermined angle, the beginning of which defines a desired park position. The improvement of the invention establishes the major discharge path for the capacitor through the wiper position responsive switch to greatly decrease the chance of the capacitor reaching the second voltage while the wiper position responsive switch is open and thereby more consistently park the wiper under the control of the wiper responsive switch in the desired park position.

Granted: 1992-07-21
Abstract: ABSTRACT  OF  THE  DISCLOSURE A paper clamping mechanism for clamping a sheet of printing paper  on  a  drum-shaped  platen  of  a  printer  is  disclosed.  The mechanism comprises a clamp member radially slidably mounted at its legs to the end surfaces of the platen, and a lever pivotted to the frame of the printer. The clamp member comprises a pressor which opposes an axial recess on the peripheral surface of the platen; the front end portion of a sheet of paper is held between the pressor and the recess during the printing operation, the clamp member being urged toward the axis of the platen by a spring. The clamp member further comprises an axially extending pin formed on a leg thereof. The lever is urged by a spring to a position at which it is stopped by a pin formed on the frame of the printer. An arm of the lever comes into contact with the pin on the leg of the clamp member when the clamp member is rotated with the platen. When the arm of the lever comes into contact with the pin on the clamp member rotated in the  printing  direction,  the  lever  turns  and  yields  upon contact; when, on the other hand, the arm comes into contact with the pin on the clamp member rotated in the reverse direction, the pin slides on the arm of the lever which is stopped by the stopper pin, so that the clamp member is raised from the platen to form a gap between the pressor and the recess on the platen.
