Abstract: A split sprocket with quick locking mechanism is made of non-metallic components.  The split sprocket is coupled to a shaft element by removable wedge members disposed between the sprocket's half members.   Key members,  in conjunction with set screws, secure the wedge members and prevent the sprocket's half members from tilting about the shaft element.  The wedge members maintain a uniform pitch diameter of the sprocket's teeth by preventing contact between the half sprocket members.

Abstract: A method for modeling traffic on a network according to a Client/Server paradigm is disclosed. The method includes the steps of exctracting the model parameters from known or measured interactions between a client node running a particular application and a server node with no other activity on the network. The method is repeated for each nodal configuration and for each application until the traffic for each node-application combination has, been modeled with no other load on the network. Scripts are created from the Paradigm parameters and are used in conjunction with a traffic generator to create discreet events mimicking the traffic which would be generated from each node. The model will insure that the traffic generated by each traffic source will be adjusted as a function of the response of the network under the load created by all of the traffic loading the network.

Abstract: A short dwell coater apparatus (10) is disclosed for applying coating material (12) onto a web (W) guided by a backing roll (14). The apparatus (10) i ncludes a coater housing (16) which is disposed in close proximity to the backing roll (14 ). The arrangement is such that the web (W) guided by the backing roll (14) moves between the backing roll (14) and the housing (16). The housing (16) defines an application chamber (18) which is open towards the web (W) and which extends alo ng the web (W) in a cross-machine direction. The application chamber (18) is connected to a source (20) of coating material (12) such that the coating materi al (12) is applied to the web (W) during movement of the web (W) past the chamber (18). The coater housing (16) has an upstream lip (22) which is disposed upstream relative to the chamber (18) and adjacent to the web (W). The lip (22) defines an upstream coating overflow (24) for permitting excess coating material (26) to flow therethrough. A flexible coater metering blade (28) is disposed downstream relat ive to the chamber (18). The blade (28) extends from the housing (16) towards the web (W) for metering the coating material (12) applied to the web (W). A perforate conduit (30) is disposed within the chamber (18) and extends in a cross-machine direction. The conduit (30) permits the flow (32) therethrough of a vortex (34) of entrained air generated within the chamber (18) such that in use of the apparatu s (10), when the vortex (34) of entrained air is generated within the chamber (18), the air (34) flows through the perforate conduit (30) away from the chamber (18) so that streaking of the coating material (12) due to the intermittent escape of the ent rained air (34) past the metering blade (28) is inhibited.

Title: Pixel control circuitry for spatial light modulator
Inventor: KORNHER KEVIN L
IPC: H04B10/118
Filed: 1994-01-11
Granted: 2004-04-27
Abstract: A spatial light modulator (10) having reduced control circuitry as compared to existing devices. Sets of pixel elements (11) share a memory cell (12), such that each memory cell (12) has the same fanout as other memory cells (12). Each pixel element (11) in a set is switched to an on or off state via a reset line (13) that is separate from that of the other pixel elements (11) in that set. Frame data is loaded in split bit-frames during a set time period, such that each split bit-frame contains only the data for pixel elements (11) on one reset line (13). Thus, the same memory cell (12) can be used to deliver data to all pixel elements (11) in its fanout because only one pixel element (11) in the fanout is switched at a time.

Granted: 1998-02-17
Abstract: A clamp is shown for holding a log of paper while a log-saw or cutting machine cuts shorter lengths of toilet-paper rolls or rolls of kitchen towels or similar all-purpose wipers from the log.  The clamp is arranged adjacent a seat or support for the log as well as adjacent a cutting blade.          The clamp includes, for each log seat, and on opposite sides of a cutting plane (T-T) through which the blade passes, a pair of adjustable and symmetrically arcuate strips (212, 214) secured to supports (207, 209).  The strips are of flexible material with end portions which tend to spring outwardly.          A strap (222) is anchored to a retention holder (224) and an adjustment holder (246).   The strap surrounds the pair of strips (212, 214) and can change the arrangement thereof.  A drive (240, 262)  simultaneously adjusts both the effective length  of  the  strap  (222)  and  the  symmetrical  angular orientations of two rods (228A, 228B) and, consequently, of two cradles (218) on which the strips are supported.

Abstract: A method of and an adjustment device for adjusting an automobile control pedals capable of pivotably adjusting the control pedal about an axis of pedal arm rotation relative to a reaction member, such as the eyelet of a cylinder pushrod for a brake pedal or a flexible cable in case of an accelerator pedal. The adjustment device allows the control pedal to be positioned to suit the needs of a particular driver. The control pedal can be pivotable attached to a frame in any conventional manner, such as with a pivot pin. The adjustment device is mounted alongside the control pedal and to the pushrod eyelet without the need of additional support hardware other than a device for acting on the control pedal. The adjustment device includes a rotatable member for causing pivotable movement of the pedal arm relative to the reaction member.      The adjustment device is maintained a predetermined distance from the pivot of the control pedal arm by a spacing device, such as a link. The adjustment device also includes a rotatable driving device for rotating the rotatable member about its axis of rotation to produce a corresponding displacement of the control pedal arm.

Abstract: An ink jet printer having a travelling ink jet pen with a foam-filled ink chamber. A separate source reservoir includes an ink outlet nozzle connectable to the pen chamber for refilling. A probe on the reservoir partially compresses the foam to decrease its ink capacity during filling. An electrical contact on the reservoir or pen detects over-filling and over-saturation of the foam to stop the filling process. As the foam is decompressed, its increased absorptive capacity accommodates any excess overflow.
