Abstract: A personal cleansing implement comprises a tubular piece of diamond-mesh scrim, which is stretched to expand the diamond mesh, gathered to form circumferential pleats, heat set in an expanded and pleated condition, and folded into a stack of layers to form a resilient batt (12). A softer layer of hydrophobic knitted material (20) lies against the top surface of the ban with its outer edge (24) wrapped around the perimeter (18) of the batt and against the bottom surface of the batt, The softer knitted layer is connected to the batt by a connecting means at the outer edge to form a dual textured cleansing implement made of hydrophobic materials and having high open area to enhance rinsing and drying. Thread stiching or thermobonding are the preferred connecting means. A tether loop (30) is connected to the implement for hanging it from a support during drying. The softer knitted layer preferably has at least one aperture therethrough.

Abstract: An electric type paper display having memory properties, rapid response times and multi-optical property display with an image of high quality is made. Each display element is wholly in contact with liquid in a cavity and the surface of each display element has a portion with a most positive charge. When an electrical field is applied from the outside, each display element is turned correspondingly to the direction of the electric field and, then electrically migrated through the liquid and attached to the inner surface of the cavity. Among multiple display surfaces of each display element an optical property is selected according to an image signal and is visible through a transparent support to an observer. Afterwards, the attached state of each display element, i.e., its display state is held by the action of an attraction force such as van der Waals force and electrostatic force acting between the circumferential surface of the display element and the inner surface of the cavity, even after the electric field is removed.

Title: Dynamic selection of interworking functions in a communication system
Inventor: ROSE EILEEN PATRICIA
IPC: H04M3/00
Filed: 1999-01-28
Granted: 2003-04-08
Abstract: The invention provides techniques for selecting, on a dynamic basis, an interworking function (IWF) that can modify a communication protocol to a particular format required by bridged terminal equipment in a communication system. The IWF can be selected to ensure compatibility between transmission bandwidth, coding and other format parameters of a call and the corresponding parameters of its destination terminal in the system. An IWF in accordance with the invention may be utilized to allow a user to bind to different terminals having different capabilities over the duration of a given call. An IWF in accordance with the invention may also be used to insert additional data, retrieved from a database of the switch, into a reverse portion of the call directed from the destination terminal to the source terminal. The invention can thus be used to ensure that the established bandwidth between the destination terminal and the source terminal is substantially bidirectionally symmetric.

Abstract: This invention provides a multistage frequency multiplier having a plurality of frequency doubters. Each doubter incorporates a three-terminal transistor device and is connected to an adjacent doubter via an interstage network. The network comprises a transmission line having its electrical parameters selected to achieve conjugate impedance matching at the intermediate harmonic frequency generated by the corresponding doubter. This network also includes a quarter-wavelength open-ended stub for suppressing a main input frequency component received by the corresponding frequency doubter. A  shunt resistor on the transistor gate is preferably used to stabilize the network.  This interstage network simplifies overall circuit topology to reduce total circuit size, and provides increased drive power levels to permit broader bandwidth and stabilize required output level from a local oscillator. This invention is particularly useful in high-speed, large-capacity communications systems and in microwave and millimeter-wave radar applications.

Title: Compression release mechanism
Inventor: STERR RANDALL E
IPC: F02N99/00
Filed: 2000-06-27
Granted: 2007-10-30
Abstract: A compression release mechanism for use in a single or multi-cylinder engine to make the engine easier to hand start. The assembly includes a compression release shaft disposed substantially within the camshaft. The compression release shaft is formed in at least two segments and can therefore be formed accurately, repeatedly and cost effectively using powder metal technology. Consequently, the weight of the flyweight member that is attached to the compression release shaft can be accurately controlled, thereby allowing the compression release mechanism to disengage at a precisely known rotational velocity of the camshaft. The compression release shaft may engage one or more valve actuation devices, which in turn force exhaust valves open during starting engine speeds. The compression release mechanism is conveniently contained within the housing by a housing wall bearing against the flyweight member and a cam bearing against an end of the compression release shaft. These bearing surfaces also hold the compression release shaft segments together.
