Title: Automated web chop-out control for cut-to-mark machine
IPC: B26D5/30
Filed: 1982-05-07
Abstract: A moving web (10) is divisible into a leader having a first set of registration marks and a trailer having a second set of registration marks. At a transition between the first and second sets of registration marks, a target is applied adjacent to the initial mark of the second set. The target is sensed (at 28) and tracked electronically to a shear (16). During an order change or a roll-to-roll change within an order, the web is automatically severed transversely by the shear (16) two or more times to chop out a portion of the leader and trailer including the transition between the sets of marks. The leading edge of the trailer is tracked to a station (44) intermediate the shear (16) and the cut-off machine (20). The cut-off machine knives "crop" cut the trailer at the first registration mark following the leading edge of the trailer and thereafter cut the trailer automatically into blanks in synchronisation with the second set of marks. Operation of the cut-off machine knives in the cut-to-mark mode is maintained without loss of synchronisation across the portion of the web chopped out by the shear. Operation intervention is eliminated, and scrap is minimised. In alternative arrangements the leader is cut by one cut-off machine (20) while the trailer is directed automatically to a second identical machine. <IMAGE>

Filed: 1982-12-22
Abstract: A streamer weight (1) can be attached to a streamer (not shown) that is trailed from a marine vessel, e.g. for measuring geological parameters of the seabed. The weight (1) comprises a sleeve member (1a) that has a longitudinal split (4) so that the sleeve member can be opened outwardly along the split and placed on the streamer, after which closure of the split will cause the sleeve member to encircle and grip the streamer.

Additionally, or alternatively, closure means such as straps (5) may be provided for holding the split (4) closed. Weight members (3), supported by the sleeve member (1a), add to the weight of the sleeve member. The weight members (3) may be in the form of longitudinally-extending metal rods embedded in the sleeve member (1a). <IMAGE>

Title: Picture image input/output system
Inventor: URABE HITOSHI
IPC: H04N1/387
Filed: 1983-07-07
Abstract: The conventional picture image input/output system is defective in that it has a large number of complicated processing steps, and therefore requires sophisticated skill and a large amount of time and labor. A lay-out retouch system has been proposed for the processing step in printing plants in recent years, but it needs a medium of a large capacity such as a magnetic disk for storing data on original color pictures, and requires a high speed computer for editing process, thereby increasing the cost of the system inconveniently. A picture image input/output system is disclosed which can obviate such defects encountered in prior art systems and is characterised in that plural original color pictures are enlarged or reduced at a predetermined magnification ratio respectively by picture image scanning device and then color separated to obtain color separation signals, such color separation signals being processed for appropriate color correction, sharpness enhancement and gradation conversion; lay-out picture images are sequentially outputted on a recording material using lay-out instruction and information; input to a control computer via an interactive graphic display. <IMAGE>
Patent GB-2294171-A (GB)
Title: Signal processing arrangement
Inventor: TUCKER CHRISTOPHER JOHN
IPC: G01S3/786
Filed: 1983-07-15
Abstract: A video signal is processed as a series of sequential line signals by a number of cascaded processing stages. A correlator 13 compares the video signal with reference data after it has passed through an initial processor stage 6 - 11. The arrangement is organised to process a large amount of data rapidly, with data from a particular stage being processed while data representing different line signals of the same video signals is being processed by a preceding or following stage. The video signal may represent a scene viewed by camera 6 and the reference data represents the expected scene (or a part) as the camera moves along an expected path. <IMAGE>

Title: A circuit arrangement and method for detecting markers in a microfilm scanner
Inventor: BUSS STEPHEN KENNETH
IPC: G06K7/10
Filed: 1983-07-22
Abstract: A circuit arrangement for detecting markers in a microfilm scanner comprises a comparator (8) for receiving an output from a photo-detector (1) and a threshold value as calculated in a microprocessor (6) and converted in a D/A converter (7). The output signals from the photo-detector are also fed to the microprocessor (6), via an analogue switch (3) and A/D converter (5), from which signals the threshold value is calculated as a function of previous values both of baseline signals generated when a marker is absent, and of deviation signals generated when a marker is present. An indication from the comparator that the output from the photo-detector exceeds a threshold level alerts the microprocessor to the fact that a marker exists. <IMAGE>
