Filed: 1974-11-14
Abstract: 1465590 Electro-photographic copier XEROX CORP 14 Nov 1974 [3 Dec 1973] 49364/74 Heading G2H A colour-corrected, substractive copying process comprises the steps of forming an electrostatic image 84 formed by light filtered through a cyan filter, and developed with cyan toner, transferring the image 84 to a support sheet 40 and then superimposing an image 86 similarly produced with magenta filter and toner. A constant voltage is applied to the sheet 40 so that where the second image 86 overlies the first 84 a lesser electrostatic field is produced causing a thinner layer (size H) than that size G, of image 84 thus compensating for magenta impurities in the cyan toner. A yellow image of thickness I is similarly superposed.

Abstract: 1383879 Welding by fusion KLÍCKNER-HUMBOLDT-DEUTZ AG 30 Oct 1973 [4 Nov 1972] 50438/73 Heading B3R  In making an I.C. engine cylinder and cylinder head assembly, a cylinder 2 and a head 1 are preformed and butt-welded together by electron beam, and, to avoid subsequent necessity of removing inwardly projecting weld metal, the cylinder and head are internally chamfered so that when they are abutted there is formed a groove 7 large enough to receive the entire portion 8 of the welding seam. To prevent entry of metal spray into the cylinder during welding, a bi-convex ring 9 is fitted within the groove 7 and becomes part of the weld. Since, as shown, the top of the piston travels past the weld seam, the latter is arranged to lie at an acute angle to the cylinder generatrix, e.g. the seam is zig-zag, as shown, or wavy. Individual cylinders may be welded to individual heads, or blocks of cylinders to blocks of heads.

The actuator may be a double-acting hydraulic motor and the charging vessel 10 is a bottom pour ladle with the sensor 20 being one or more load cells disposed between a ladle rest 21 and a ladle support 22. The load cell may be of the strain gauge type (20<SP>1</SP>, Fig. 2) incorporated in the ladle suspension (33). The load sensor 20 produces a signal fed to a differentiating circuit 23 from which a signal is fed to a differential amplifier 27 as is also a signal from a presettable signal generator 30. The error signal from the amplifier 27 is fed to a further amplifier 32 and thence to a servo or solenoid controlling valve 17. The charging vessel may be a vacuum degasser or a tundish in a continuous casting plant. In the latter case its weight may be monitored by the load sensor to produce a signal which is used in a similar feed-back system to maintain a constant level of metal in the tundish.

An analogue computer 11 is controlled by parallel logic circuit 10. A plurality of outputs from analogue computing elements are applied to multiplexer 16 from patch panel 11a and converter 20 produces corresponding parallel digital signals. Serializer 20a supplies these signals either to a recirculating memory 1Oc which can store a plurality of digital words from converter 20, or directly to logical elements. Output from circuit 10 is fed to a shift register 25 which may have a serial or parallel output to converter 26 which feeds analogue signals to computer 11 via panel 11a. A comparator unit 30 receives analogue signals from computer 11 and supplies two-state signals representing the results of comparisons of pairs of the analogue signals to circuit 10. A switching unit 40 is controlled by circuit 10 to connect the outputs of selected analogue computing elements to the inputs of other selected computing elements. The memory comprises two magnetostrictive delay lines 256, 266, Fig. 10, providing one and 255 word delay respectively, and a return loop 270. Data is entered at 294 with load terminal 273 energized. The first three bit positions of a word are available for flag bits. To locate a word with a flag bit in the first position for example, terminal 276 is energized at T 1  in each word cycle. When the desired word reaches output terminal 285, gate 277 is enabled and flip-flop 281 is set to indicate that the flagged word has been found and may be read out. If write terminal 287 is energized the return loop is blocked at gate 271 and the data bits of the flagged word are erased, but a new word may be inserted from terminal 294. A flag bit may be advanced to the next word by energizing terminal 295. Detection of the flag is as above, but gate 296 is enabled to block the flag re-entry at gate 271 and instead enter it one word later (delay 298). Similarly, a flag may be retarded one word by energizing terminal 299, the recirculation of the flag being blocked at 271 when gate 300 is enabled, and a new flag being inserted over line 301, bypassing the one word delay 256.
