    Abstract: 1,204,279. Read-only stores. INTERNATIONAL BUSINESS MACHINES CORP. 23 April, 1969 [2 May, 1968], No. 20760/69. Heading G4A. An optical data storage device comprises a photochromic glass plate having at least one non-photochromic elemental area, means for rendering the parts of the plate other than the non-photochromic elemental areas opaque, and means for determining whether or not a light beam passes through a selected elemental area. In Fig. 1, storage plates 6a-12a are of photochromic material except at bit positions where a 1 is stored which are perpetually transparent. Flash-lamps 6b-12b can render the photochromic material of the respective plates 6a- 12a opaque and flash-lamps 6c-12c can render them transparent. To read a given bit-position of a given plate, light from source 1, polarized at 4 is deflected to the given position by electrooptical deflector 5, the flashlamps rendering the given plate opaque and the others transparent to read out the bit to photo-cell 21. Each plate may alternatively consist of the above photochromic plate (with the non-photochromic insertions for 1) sandwiched between two transparent plates, the flash-lamps directing light into the sandwich via wedge-shaped lightconducting elements. A second embodiment uses plates of either form, each being sandwiched between two plano-convex lenses to form a double-convex lens, further doubleconvex lenses being interposed between successive ones of the latter, and the electro-optical deflector following the sequence of lens. The storage plates in the Fig. 1 embodiment could alternatively each be a selectively-etched photochromic layer on a glass support.

    Abstract: 1,146,492. Delivering sheets. HONEYWELL Inc. 20 May, 1966 [27 May, 1965], No. 22690/66. Heading B6H. [Also in Division G4] Cards C1, C2 ,are deflected on the fly into a stacker 72, Fig. 1, by a solenoid actuated plate 20, the actuation of the solenoid being initiated by card presence detectors PD1, PD2. When PD1 is uncovered by the trailing edge of a card, the solenoid is energized after a predetermined delay so that the card subsequently enters the stacker in a normal stacking position by way of rollers 73, guide fingers 74 and keeper roller 75, see Fig. 3. If the card is to be stacked in an offset position, as at 70 1 , the output of PD2 is used to energize the solenoid. Other card detectors PD3, (PD4) indicate if a card overshoots the deflector or if a stacking jam occurs. Plate 20, Fig. 3, is mounted adjacent the solenoid 12 on flexure members, and comprises overlapping thin plates 23, 25, 27 of different sizes, giving a whip-lash action with substantial follow-through. Backing plate 40 has a return spring 43 for plate 20 and a vent hole 45 to assist in damping the return motion of plate 20 and reduce aerodynamic drag as plate 20 moves away from plate 40.
