Title: Method for separating profiled foils
Inventor: BAR MARTIN
IPC: B65B61/18
Filed: 2000-07-07
Abstract: The method for separating a profiled foil (5) is carried out using a rotating separation foil (1) which forms a planar surface with a circular periphery (11). The separation foil is rotated (la) about the circle center (10) and in the plane (10a), the foil plane, which is spanned by the surface. The periphery is brought into contact (15) with the profiled foil by the execution of a relative movement (1b). In this, through abrasion, material (6) is removed and a separation gap (51) is produced in the profiled foil. Material is largely removed from the profiled foil only.

Inventor: KELLY WILLIAM
IPC: G01J3/10
Filed: 2000-07-28
Abstract: An illuminator (1) has a printed circuit board (5) supporting a ring of light emitting diodes (LEDs) (6). An annular Fresnel lens (7) and the board (5) are both mounted in a housing (2) having a central through-hole (3) for a camera field of view.  The lens (7) mixes light from the LEDs (6) in the tangential direction and it also controls spread in the radial direction so there is uniform illumination over a target plane (4). Any individual point on the target plane (4) receives illumination from over 25% of the light sources (6). The illuminator is thus particularly effective, compact, and suitable for a wide range of industrial applications. Choice of lens and of the spatial arrangement allows versatility. The illuminator design is easily scaleable by changing the size and spacing between the light sources.

Title: Routing area update in packet radio network
Inventor: FORSSELL MIKA
IPC: H04B7/26
Filed: 1999-02-11
Abstract: A method of transmitting data in a packet radio network to a mobile station (MS) performing a routing area update. The packet radio network transmits data (2-0, 2-3a) to the mobile station (MS) via a first support node (SGSN,).  The mobile station (MS) sends a routing area update message (2-1) to a second support node (SGSN2) which sends to the first support node (SGSN,) a request (2-2) for context data (2-5) of the mobile station from the first support node. The first support node sends the requested context data of the mobile station (2-4), waits for a predetermined period of time (3-b), and sends additional data to the second support node (3-c). The predetermined time (3-3b) may be fixed, depending preferably on the quality of service of the connection used by the mobile station. Alternatively the predetermined period of time expires when the second support note (SGSN2) sends to the first support node (SGSN,) a separate acknowledgement message indicating that the second support node has received the context data of the mobile station.

Inventor: CHANG KOK-WEI
IPC: H04J14/02
Filed: 2000-12-15
Abstract: Interleaver/deinterleaver apparatuses for combining/separating optical channels are described. An interleaver/deinterleaver apparatus is described as folded when an optical signal is directed through a single crystal multiple times. Multiple-pass refers to the optical signal following a (folded) path through the apparatus multiple times. When operating as an deinterleaver, the interleaver/deinterleaver separates an optical signal (e.g., WDM signal) into subsets of optical signals (e.g., channels). In one embodiment, deinterleaving optical signals separates an optical signal into even and odd International Telecommunications Union (ITU) channels. When operating as an interleaver, the interleaver/deinterleaver mixes subsets of optical signals (e.g., channels) into a multiplexed (e.g., WDM) optical signal. The interleaver/deinterleaver apparatus can be used to increase the bandwidth of an optical network. For example, the interleaver/de-interleaver can be used to interface components designed for a first channel spacing (e.g., 100 GHz) to components designed for a second channel spacing (e.g., 200 GHz). In one embodiment, interleaveing combines even and odd ITU channels into a single optical signal.

Title: Large round baler
Inventor: VIAUD JEAN
IPC: A01F15/07
Filed: 2001-02-07
Abstract: The technical problem to be solved is that of providing a non-stop, large round baler that has a weight that is less than known non-stop, large round balers. This problem is solved by a structure which includes separate upper and lower baling chamber sections, with the upper baling chamber section being designed to form a major portion of a baling chamber and being mounted to opposite baling chamber walls for moving fore-and-aft together with the walls between a rear location, wherein it cooperates with the lower baling chamber section to define a rear baling chamber, and a forward location wherein it cooperates with the lower baling chamber section to define a front baling chamber. During the time after a bale has been completed by the rear baling chamber and the upper baling chamber section is moving from the rear to the forward location, a crop feed rotor that is located at the lower baling chamber section is operated in reverse so that crop is accumulated in a zone wherein it becomes housed by the front baling chamber when the upper baling chamber section reaches its forward position. In the meantime, the formed bale may be deposited onto the ground, or wrapped with sheet or net material and then deposited onto the ground.

Title: Method and apparatus for displaying and navigating containment hierarchies
Inventor: ROCHFORD SUZANNE L
IPC: G06F3/033
Filed: 2000-05-19
Abstract: A method for use in a computer system for displaying a containment group such as file folder hierarchy. The method displays a direct containment hierarchy for the selected containment group or file folder, and also displays a list of contents of the selected containment group or file folder. A direct containment hierarchy displays only file folders or containment groups which directly or indirectly contain the selected containment group or file folder.  In this manner a large number of file folders or containment groups which do not ultimately contain the selected file folder or containment group are not displayed, thereby simplifying the display, and ensuring that the entire direct containment hierarchy can be shown on a single display screen without the need for scrolling in order to obtain or ascertain the context of the given file folder or containment group.

Inventor: SCOTT KEVIN ANTHONY DAVIS
IPC: A01K91/08
Filed: 2001-04-23
Abstract: The invention described relates to a downrigger line clamp mechanism used in downrigger fishing and includes an adjustable clamping force for adjusting the overall release tension of a fishing line. The pre-stressed line clamp mechanism includes a pair of pivotally engaged, elongate arms which, when assembled, are resiliently flexed such that one portion of the arms, the proximal grip portions, are outward bowed, the tips of the proximal grip portions pinching together, thereby biassing another portion of the arms, the jaws, towards a closed clamp position. The line clamp mechanism uses an adjustable compression-force biassing device movably mounted between the tips of the proximal grip portions of the arms. The biassing device may include spacers of different spacing dimensions, each spacer being positionable into an active position between the tips of the proximal grip portions of the arms by moving the biassing device relative to the arms. The magnitude of clamping force at the jaws is adjustable by adjusting the spacing between the tips of the proximal grip portions of the arms.

Title: Collection makefile generator
Inventor: JAMESON KEVIN W
IPC: G06F9/44
Filed: 2001-07-05
Abstract: Collection makefile generators generate comprehensive makefiles for processing collections of computer files. In operation, the present collection makefile generator dynamically discovers collection content files, classifies them according to content type and required processing actions, and then generates a makefile for performing those actions. Importantly, all build order dependencies are properly maintained among multiple collection products and among individual collection content files. Automated collection makefile generators drastically improve the productivity of human workers by effectively reducing makefile creation and maintenance costs to zero. Collection makefile generators thus enable humans to easily generate complex makefiles in an automated, scalable way that was not previously possible.
