Abstract: In a mobile cellular communication system, a base station is wired to a Local Area Network (LAN), and has wireless communication with a plurality of mobile stations.      Multipath fading is substantially reduced in the system by utilizing antenna diversity techniques at the base station and each of the plurality of mobile stations.      The combination of the independent operation of antenna selection diversity at both a base station and a mobile station results in the selection of the best propagation path between the two stations.

Abstract: To the housing part of a backflow-preventer for a sanitary device there is fastened an outer sleeve, made from elastomeric material, exhibiting a sleeve section which is distanced from the housing part.  The outer sleeve embraces an inner sleeve which is fixedly supported to the housing and includes a supporting section, which is dimensioned such that the inner sleeve, when acted on by water flowing in the direction of flow, cannot fold inward.          The sleeve section bears, under pretensioning, against the supporting section and is expanded by the pressure of the water so as to clear an opening between the sleeve section and the inner sleeve.  If the water current is interrupted, the outer sleeve immediately bears again against the inner sleeve.  The end sections  of the inner and outer sleeves are configured like a sealing lip.  The backflow-preventer prevents water from flowing back, even under the least underpressure on the feed side.  Moreover, it is not sensitive to foreign bodies.

Title: Apparatus and method of ensuring proper machining of a worksheet
Inventor: LINDSTROM MIKKO
IPC: B23Q3/155
Filed: 1992-09-15
Granted: 2003-04-29
Abstract: To ensure that a worksheet (10) ineffectively operated on, the present invention system monitors the life expectancy of a tool (T1) by counting the number of hits (71) the tool has made so that when it is reached, the tool is replaced by a spare tool (T9). Alternatively or in combination therewith, in place of monitoring the life expectancy of the tool, the operational effectiveness of the tool is monitored (62). Thus, anytime that the operational effectiveness of the tool is deemed to fall below a given standard, the tool is replaced by a spare tool. The replacing of the tool by a spare, and the subsequent replacement of the spare tool by yet another spare can go on ad infinitum. With such a system, severe failures of tools are prevented.

Title: Multiple saw blade adjustable dado cutter assembly including a cam assembly and nestable dado blades
Inventor: MCCORD WILFRED M JR
IPC: B23Q17/22
Filed: 1994-05-06
Granted: 2005-01-04
Abstract: A multiple saw blade adjustable dado cutter assembly. The cutter can be used with a table saw or a radial arm saw, for example, to make dado cuts in board lumber. A pair of cooperating cams, each connected to a saw blade, can be adjusted to make a dado cut of a desired width. If the desired dado width is wider than the two blade configuration can cut, a center cam attached to another blade can be inserted between the pair of cooperating cams. With the three blade configuration, the three cams cooperate to allow the three blades to be spaced for the desired width of cut. In both configurations and at any spacing width, the two or three blades employed remain in a generally parallel alignment and transverse to the axis of the arbor on which the assembly is secured. To permit the blades to function with this geometrical relationship and to be adjustable, not all of the blade teeth lie in the same plane. The sequentially operating three or more cam assembly has uses beyond dado cutting. Also, the blades can be made to mount directly onto a saw arbor with spacer washers taking the place of the cam assembly. For industrial applications, mare than three blade configurations are envisioned.

Abstract: An apparatus (10) for perforating corrugated tubing (T) is disclosed.  The apparatus (10) receives tubing (T) to be perforat-ed along an axial path coincident with the axis of the tubing (T).  A plurality of feeder-cutter wheels (12) drive the tubing (T) through the apparatus and concurrently perforate the tubing in the valley of its corrugations.  Each feeder-cutter wheel (10), and the drive shaft (14) each wheel (12) is mounted upon, is offset at an angle relative to the axial path, this angling facilitating un-iform perforations at higher speeds.  An alternate embodiment of the apparatus has six feeder-cutter wheels (12) disposed within four distinct planes.  This design permits the wheels (12) to be interchangeable with different wheels, allowing the apparatus to perforate tubing of different diameters.  The alternate embodiment also offsets the wheels at an angle to facilitate perforation at high speeds than previously known in perforating apparatus.

Granted: 2001-01-02
Abstract: Absorbent articles such as disposable incontinent briefs, diaper holders, training pants feminine hygiene garments, and the like, having ex-tensible side panel features that improve the dynamic fit of the diaper around the legs and waist of the wearer. Such absorbent articles comprise a con-tainment assembly comprising a liquid pervious top-sheet; a liquid impervious backsheet; an absorbent core disposed between the topsheet and the back-sheet; and extensible side panels, each comprising a waist panel and a thigh panel disposed along each longitudinal edge of the containment assembly in the first waist region. The waist panel and the thigh panel are operatively associated so that the waist panel has a primary direction of extensibility in one direction and the thigh panel has a primary direction of exten-sibility in a different direction. This forms a multi-directional extensible side panel wherein the waist panel provides tension around the wearer's waist to maintain fit about the waist and to hold the diaper on the wearer, and the thigh panel expands and con-tracts to maintain a dynamic fit around the leg of the wearer. Thus, the waist and thigh panels reduce the negative effects of the dynamic forces on the ab-sorbent article, such as sagging and gapping that can cause leakage, while increasing freedom of motion and wearer comfort.
