Title: Optical character recognition
Inventor: BERNZOTT PHILIP
IPC: G06V30/10
Filed: 1989-08-07
Abstract: A page of printed text and graphics is scanned and a bit-mapped representation of the page is stored in a memory. A processor processes the bit-mapped image to produce an output comprising coded character representations of the text on the page. The page is parsed to distinguish text from graphics and to allow for production of the output characters in a logical sequence corresponding to that in which they would be read by a human reader. The characters are recognised by a combination of feature detection and template matching methods. A number of methods for feature detection such as use of statistical data and polygon fitting are disclosed. Final recognition employs context analysis, e.g. to an apostrophe, or between upper and lower case "s".

Title: Bread processing; conveyors.
Inventor: HIGGINS MICHAEL
IPC: A21C13/02
Filed: 1992-01-06
Abstract: Tins 20 loaded with bread dough for proving are delivered from a first conveyor 30 through a transition zone 35 to a second conveyor 31 e.g. at right angles to the first. A first photoelectric emitter/sensor 40, 39 detects if a loaded tin is present at the end of the first conveyor 30. A second photoelectric emitter/sensor 42, 41 detects if space is available on the second conveyor 31 to receive a tin from the transition zone 35. Emitter/sensor 44, 43 detects if space is available on second conveyor 31. A proximity switch (49, Figure 2) detects when a full batch of tins is present at the prover inlet station and sends a signal to over-ride all other sensor/emitters to prevent further tins entering the prover inlet station as a batch of tins are being located into the prover. A stop bar 45 is activated to prevent a tray entering the transition zone 35 from the first conveyor 30. Further details of the process are given, and Figure 6 illustrates a delidding apparatus comprising an air jet arrangement (51), and suckers (52). <IMAGE>

Title: Control of resistance welding
Inventor: NATZLER PIERRE J
IPC: B23K11/25
Filed: 1992-07-01
Abstract: When making resistance welds a splash may occur, that is to say a situation where the welded material in the nugget escapes so leaving a defective weld. When such a splash is detected, the weld control incrementally decreases the weld current by reducing the phase fraction, i.e. that fraction of each AC cycle during which welding current flows, for the next weld which is made. Splash may be detected by monitoring the voltage for drop below a pre-set valve before a pre-set time. <IMAGE>
