Title: Cigarette making machine
Inventor: DAWSON JOHN
IPC: A24C5/18
Filed: 1993-08-18
Abstract: In a cigarette making machine, tobacco is arranged to be showered towards two suction bands 304, 306 to form tobacco sub-streams 305, 307 on the respective bands which are then merged to form a single cigarette filler stream which (possibly after trimming) is enclosed in a wrapper web 312 to form a continuous cigarette rod, and the machine includes means for disturbing at least part of the tobacco of at least one of the tobacco sub-streams before the two sub-streams are merged. This disturbance of the sub-streams preferably causes or permits a degree of reorientation of the disturbed tobacco and a degree of interengagement between tobacco particles of the two sub-streams. In one example at least part of this disturbance is caused during the transfer of both sub-streams to a further suction band 310 which carries the merged stream to the wrapper web. <IMAGE>

Title: Disparity coding images for bandwidth reduction
Inventor: SEFERIDIS VASSILIS
IPC: H04N13/00
Filed: 1993-12-31
Abstract: First and second images (such as the left and right images of a stereo pair) are initially divided (30, figure 2) into corresponding blocks of a first size and, for each block of the first image, a search is made (32) for a block at corresponding and nearby positions in the second image. If the search is unsuccessful, the first image block in question, and the blocks searched in the second image, are subdivided and the search repeated for each sub-block. When a reasonable match is made, the required shift is stored and a series of distortions (34) - see figure 4 - are applied to the selected second image block to identify (36) which distortion, pattern, if any, improves the match. The resulting data, from which the first image may be recreated comprises, for each first image block or sub-block, identification of the selected second image block or sub-block in the second image and the shift and distortion applied. <IMAGE>

Title: Load balancing across the processors of a server computer
Inventor: STANFORD-CLARK ANDREW JAMES
IPC: G06F17/30
Filed: 1996-01-26
Abstract: A server computer connectable to a network has a plurality of processors (20, 30, 40) arranged to provide a service to one or more client computers (50) connected to the network. The service involves the provision of blocks of information to a client computer. According to preferred embodiments of the invention, each processor in the server has block retrieval means (80), employed in response to a request from a client computer for a particular block from that processor, to retrieve data from data storage (120) in order to construct a file representing the requested block, the file including references to subsequent blocks requestable by the client. Additionally, means (100) is provided for periodically determining activity data for the processor for inclusion in a load distribution record maintained for all of the processors of the server. Decision means (90) is then used which, for each reference to a subsequent block in the file, is arranged to determine, based on the load distribution record, which processor should service a request from the client computer for that subsequent block and to include an address for that processor in the file. The file is then sent to the client computer. The technique may be employed on a parallel Web server providing Web pages to clients over the Internet. Effective load balancing across the processors of the server is possible, thereby enabling "toasting" of a particular processor to be averted.

Patent GB-2301927-A (GB)
Title: Ferroelectric liquid crystal displays with greyscale
Inventor: HUGHES JONATHAN RENNIE
IPC: G09G3/36
Filed: 1995-04-10
Abstract: The invention provides a ferroelectric liquid crystal display with uniformly spaced greyscale levels. The invention uses a bistable ferroelectric liquid crystal display formed by a layer of chiral smectic liquid crystal material between two cell walls. The walls carry e.g. line and column electrodes to give an x,y matrix of addressable pixels, and are surface treated to provide bistable operation. Each pixel may be divided into subpixels thereby giving spatial weighting for greyscale. Temporal weighting of greyscale is obtained by switching a pixel to a dark state for time T1 and a light state for time T2. When T1 and T2 are not equal, four different greyscales are obtainable; i.e. dark, dark grey, light grey, and light. The present invention provides a required uniform spacing of greyscale levels by addressing each pixel two or more times in one frame time. Each pixel is blanked then strobed, two or more times in each frame time; the relative times between banking and strobing, at least four different time periods, are varied to give the desired greyscale levels. The temporal and spatial weighting may be combined to increase the number of obtainable greyscales. Further, the relative intensity between adjacent subpixels may be adjusted to vary the apparent size of the smallest subpixel; this is useful when subpixel size is near to manufacturing limits.
