Abstract: 1,231,622. Feeding sheets. RANK XEROX Ltd. 16 April, 1968 [21 April, 19671, No. 59156/70. Divided out of 1,231,621. Heading B8R. Original documents are fed from a document support tray 210, Fig. 4, to the exposure transport system of a xerographic machine. The tray is pivotally mounted between side frame plates 220, 222 via pivot shaft 211. A document support member 212 projects above the surface of the tray so that documents have a draped or arched configuration to reduce the tendency of documents to stick together. A pair of upstanding paper guide plates 214, 216 are mounted for complementary movement by a cable 187, which cable also adjusts paper guide plates (191, 192), Fig. 6 (not shown), in a document return conveyer and stacker apparatus located below tray 210. The pivoting of document support tray 210 about shaft 211 is adjustably controlled via cables 231 by an air motor 234. An A.C. motor MOT-1 continuously drives via flexible chain 226 a drive sprocket 229 of an electromagnetically actuated clutch and brake assembly 230 which provides intermittent rotation of a drive shaft 256 via a coupling 257. An idler shaft 255 is driven by overhead advancing guide belts 266. Documents are fed from tray 210 by a nudger or feed wheel 250 formed from a material having a high coefficient of friction which is driven from idler shaft 255 so as to have a peripheral velocity of four inches a second, and thence by a flexible separator feed belt 260 also formed of material having a high coefficient of friction and driven from shaft 256 so as to have a peripheral velocity of fourteen inches a second. A retarding abutment member (282), Fig. 7 (not shown), co-operates with belt 260 to form a wrap and thus separate adhering overlapping sheets. Absence of documents on tray 210 is detected by a pair of wire rod members 238, a magnet being attached to an upper end of one of the members for actuation of a magnetically actuated reed switch SW-6. A motor continuously drives a shaft fixedly carrying a plurality of axially spaced friction roll members 316, Fig. 8, which engage a plurality of idler roll members 330 rotatably mounted on a shaft 327. Shaft 327 fixedly carries a plurality of sheet interrupting members 326, each having a plurality of notched projections which extend into the spaces between friction roll members 316 to form a sheet registration gate or sheet interrupting means. The sheet registration gate assembly is indexed to a first position in response to an electrical signal to an electromagnetic clutch 321 to interrupt the advancement of the leading edge of a sheet which forms a hump or buckle in the sheet, and to a second position which releases an engaged sheet into the bite of a pinch roll arrangement. Documents fed from support tray 210 pass idler rolls (278), Fig. 7 (not shown), which co-operate with the drive pulley 213 of belt 260, and if the idler rolls move more than an amount corresponding to the passage of more than a single document or a crumpled document the sheet interrupting means inhibits the release of a document.

Abstract: 1,265,458. Semi-conductor devices. SIEMENS A.G. 15 Oct., 1970 [16 Oct., 1969], No. 48957/70. Heading H1K. The invention is concerned with methods of separating semi-conductor chips 2, 3 carrying beam leads 26-28 from a semi-conductor wafer 1 in a manner which both simplifies the manufacturing process and minimizes the amount of space wasted on the wafer 1. In a first method, the wafer 1 including, at its upper surface, circuit components and electrodes 4, e.g. of a Au-Pt-Ti layer sequence, is stuck by its lower surface to a glass plate 10 and the upper surface is scored along lines 11 defining the outlines of the chips. The upper surface is then covered with an etchable material such as Cu or Ni, and areas of the electrodes 4 are exposed therethrough by a photo-resist etching method. Au beam leads 26-28 are electrodeposited so as to contact the exposed areas of the electrodes 4 and to overlap.the neighbouring chip area, and the remainder of the Cu or Ni layer is then etched away leaving the beam leads 26-28 detached except where they contact the electrodes 4. The lower surface of the wafer 1 is next detached from the glass plate 10 and stuck to a rubber foil, on which it is broken into discrete chips along the score lines which chips are then spaced apart by stretching the foil. Finally, the chips, complete with laterally protruding beam leads 26-28, are removed from the foil. In a modification of this method the glass plate 10 is dispensed with and, after forming the beam leads as described above, the upper surface of the wafer 1 is stuck to the rubber foil and the exposed lower surface is scored prior to breaking and stretching the foil to separate the chips as above.
