Title: Selectively encodable envelope insert and related sorting apparatus
IPC: G06K19/06
Filed: 1975-03-11
Abstract: 1498197 Document sorter and document DOCUTRONIX Inc 11 March 1975 10055/75 Heading G4M [Also in Division B6] A card for use as a mail order form for ordering units and indicating method of payment has a central portion 12 containing instructions and a magnetic encoding bar and, at each end of the central portion, a separate portion 14, 16 joined to the central portion at a line of weakness allowing easy separation of the portions. One portion 14 is used to indicate a method of payment and contains five magnetic encoding bars. The other portion 16 contains four sections separated by lines of weakness with each section containing one magnetic encoding bar. The presence or absence of portion 14 indicates payment by cheque or postal order respectively. The number of bars in portions 12 and 16 indicate the number of units required. The card is inserted in an envelope and posted. The received envelope is opened 52 and the card is fed to a reader 54 which first magnetizes the bars and then counts their number. The count is fed to a logic section 60 and the cards are fed to Pocket Sections 63. The position of the cards is detected by sensors 64 which transmit the count value to Registers 65. Ten different count values can be obtained and each Pocket Section contains pockets for two counts. As each card reaches a section its count value is stored in the associated Register and if the count corresponds to the pocket value the card is supplied to the pocket. For each value two pockets are supplied so that one can receive a fixed number of cards before filling of the other pocket commences and so that one can be emptied while the other is being filled. The number of cards in a pocket is counted by the logic section. The cards with no code or an unreadable code are stored in a separate section.

Title: Holographic memory with same reference beam used for writing  and reading
IPC: G11C13/04
Filed: 1971-04-20
Abstract: 1342501 Magnetic storage systems RCA CORPORATION 20 April 1971 [23 April 1970] 10070/71 Heading H3B Tnformation is stored in a magnetic hologram by Curie point writing, and is retrieved by illuminating the hologram with the same reference beam as is used in writing to reconstruct the information or to use the Faraday effect. In Fig. 1 a pulsed laser gives a polarized output ray which may be rotated through 90 degrees at 11 and may then be deflected at 12. The ray is reflected from mirror 15 to lens 16 and beam. splitter 17 where it is divided into a reference beam and an object beam. The reference beam is incident on a small region of a Mn-Bi storage plate 26, while the object beam passes via polarizer 18, lens 20, mirror 22, lens 24 to a holoarray 27. This latter array of holograms guides any ray incident on it to a data bearing object 30, and the modulated ray is focused on to the area of the storage plate illuminated by the reference ray. The polarizer 18 is oriented to allow the object beam to pass when writing is required, but blocks the object beam when the polarization rotator 11 is activated during reading. Thus during reading only the reference beam is incident on the storage medium, and the stored data is reproduced in the area of object 30. If non- destructive reading is required, the laser output is reduced. The data bearing object 30 comprises an array of light switches which may be made opaque or transmissive by applied voltages. The object contains integral transistor flip-flops which set the voltages in response to external data signals. Thus the external signals set the switches, and during writing the pattern of opaque and transmissive areas is stored as a thermomagnetic hologram. During reading, the reconstructed image is sensed by photodetectors integral with the light switches, and the detector outputs trigger the flip-flops. The electrical state of the flip-flops thus forms the output signals during reading. Any discrete area of the storage medium 26 may be selected by the deflector 12, which may be an ultrasonic device. Path folding may be used in region 13 of Fig. 1 if the angular deflection is small. A deflector comprising polarization rotators separated by double-refracting crystals such as calcite may also be used. The beam splitter may be a partially transmissive mirror or a polarizing device comprising a pair of birefringent prisms or a birefringent crystal in a liquid of appropriate refractive index. A single area of the storage medium may be erased by incident light at an intensity lower than that for Curie point writing, accompanied by a bias field too low to erase non-illuminated areas. Faraday effect reading may also be used.
