Title: Remote postage meter resetting method and system
IPC: G07B17/00
Filed: 1973-11-15
Abstract: 1417872 Electric selective signalling PITNEY-BOWES Inc 15 Nov 1973 [4 Dec 1972] 63131/73 Heading H4K [Also in Division G4]  Postage meters 24 connected to a data centre 12 are equipped with locks 26 having combinations which vary in pseudo-random manner, the combination required at any time to unlock a meter being transmitted thereto upon receipt by the centre of a valid request for recharging the meter.  Communication is via a "touch-tone" telephone 16, a data set 18 and a "voice answerback" unit 22. Each meter contains a register for accumulating the total postage used and a register which is incremented with each increment of prepaid postage with which the meter is recharged, and decremented as this postage is used. Means are provided to prevent more postage being used than has been paid for. When a meter needs recharging, the user phones centre 12 which requests the user's account number and the meter identification number. These are checked by a computer 20; if they are valid, the contents of the meter registers are requested. The computer checks their sum (which should be constant between rechargings) against the previously stored sum, if there is agreement, the computer checks that the user's account contains sufficient to pay for the postage increment requested and that all the combinations have not been used, transmits a new combination, and updates its files The user enters the new combination on keys 30, 32 and then the new increment by means of knob 28. The user is given three chances to transmit the correct account and meter numbers and register content. If these are not received, computer 20 breaks the connection or instructs the user to phone for assistance. There is also provision for checking that a meter was recharged after the last request, and that the registers have not or are not about to overflow.  A new combination is generated by an algorithm (Fig. 3, not shown) each time a request is validated, only the current combination being stored. Each lock may contain its combinations on punched tape, or may comprise means for generating the combinations synchronously with generation by the computer.

Abstract: 1,245,093. Character recognition. POST OFFICE. 3 Dec., 1968 [7 Dec., 1967], No. 55757/67. Heading G4R. In pattern recognition apparatus, a group of binary digits representing an input pattern to be classified is compared with groups of stored digits representing known patterns of a particular class, logical means connected to the comparing means also receiving other sets of stored binary digits, each set representing the relationship between corresponding digits of two groups representing different patterns of the same class, and output means responsive to the logical means to give a pattern class indication. A photo-cell matrix senses an unknown alphanumeric character, the matrix output being stored. Forty 12-tuples from this are further stored, then for each possible character in turn, each of the forty 12-tuples is supplied in turn for identity comparison of each bit with the corresponding bit of each of 22 stored reference 12-typles which were obtained from a set of examples of the possible character as the first 22 different examples of that 12-tuple encountered. The 22 x 12 bits from this comparison (in the case of a given 12-tuple for a given possible character) are combined in a "main logic box" with 231 x 12 bits expressing the inter-relationship between corresponding bits of each possible pair (of examples) of the 22 examples of the given 12-tuple, 231 being ¢(22)(21). The interrelationship bits were originally derived on a computer using a set-theoretic algorithm specified. The functions performed by the "main logic box" are specified in similar terms. For each of the forty 12-tuples of each of the possible characters, the "main logic box" produces a pulse or not, and these pulses are counted in the appropriate ones of various class counters (one per possible character), the largest count finally identifying the character. During operatioion, the reference 12-tuples and the inter-relationship bits are loaded into stores from a backing store (magnetic tape or disc) before each of the forty 12-tuples is considered, together with a class number (which routes the output of the "main logic box" to the appropriate class counter), a 12-tuple number (which selects the appropriate 12-tuple of the unknown character) and "start", "last batch" and "new 12-tuple" control bits, a check sequence also being read out (first).

In an alternative embodiment, Figures 3, 4 (not shown), the body (33) includes a folded condom (28) inserted into an inner cavity (34). Insertion of a male genital organ into the candom causes expansion of body (33).

Abstract: 562,378. Rontgen-ray apparatus. CASPERSZ, M. L. B. J. Oct. 19, 1942, No. 14633. Convention date, Sept. 15, 1941. [Class 98 (i)] Radiographs, in which either the vertical or horizontal measurements between different parts of the image are accurate, are produced by using for the exposure a beam passed through a horizontal or vertical slit respectively and moved at uniform speed in a direction perpendicular to the slit whilst being maintained parallel to its original plane. The exposure is therefore made progressively by a beam which in one dimension is substantially non-divergent and perpendicular to the image surface, so that distortion of the image in this dimension due to a non-planar object lying in a divergent beam is avoided. In the apparatus shown, the ends of a tapering hollow X-ray shield 45 are supported by anti-friction rollers so as to be horizontally movable in framzs 38, 39, which frames are vertically movable on rails 41 carried by upright members of the framework and are counterbalanced. The X-ray tube is mounted at one end of the shield, at the other end of which are runners in which a plate (not shown) provided with a slit may be held with the slit extending either vertically or horizontally. During the exposure the shield, X-ray tube and slotted plate are moved together either horizontally or vertically respectively by dashpot controlled devices 63, 57, the plungers 64 of which are alternatively connected to corresponding fittings on the shield by telescoping sleeves 61, thus moving the slot in a direction perpendicular to its length over the exposure area. The subject is situated between a ray-permeable partition 40 and a film cassette mounted in runners 36.
