Title: Improvements in data transmission
IPC: H04L1/00
Filed: 1963-07-10
Abstract: 1,040,019. Correcting electric digital data errors. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 10, 1963 [July 10, 1962], No. 27251/63. Heading G4A. A circuit for correcting errors in words, including check bits, includes a decoding shift register which for each bit of a word recirculates selected bits of the word a predetermined number of times, performing a logical operation on them as it does so, and a monitoring means which, when a particular combination of bits occurs in the shift register, causes an error to be corrected. In one form, information bits Do are gated at P into a decoder 2, and simultaneously at P1 into a shift register 4 under the control of timing signal A. The decoder which is stated to be of known type (Peterson decoder) consists of a shift register formed of triggers T1-T8, inverters I and a number of additional connections including " exclusive or " gates #, #1, #2, #3. When a word consisting of eight bits has been entered into the shift register 4 and the decoder 2 the signal A is cutoff. The choice of the check bits in the word and the arrangement of the decoder is such that if an error in the first bit S has occurred the eight outputs E1-E8 of the decoder will all be energized, if the decoder is recirculated nine times, and an AND gate # 8 will be energized to bring up the one output of a trigger T9 to indicate that the bit S<1> is in error. This one output is combined in an exclusive or gate #4 with the first bit S, in the shift register 4 so as to effectively invert or correct this bit. A trigger T10 is set to the correct value.

Abstract: 1,235,702. Coin-freed apparatus. GILBERT & BARKER MFG. CO. 10 June, 1968 [8 June, 1967], No. 27515/68. Heading G4V. [Also in Division A4] A fluid dispenser includes a counter, a first signal generator responsive to the insertion of coins, tokens and/or banknotes in the dispenser to apply credit pulses to the counter, a second signal generator responsive to the delivery of fluid to apply debit pulses to the counter, the dispenser being disabled when the counter registers zero credit, and a third signal generator applying debit pulses to the counter to count it down to zero if a customer terminates delivery of fluid before he has used all his credit. Insertion of a coin or bank-note in a petrol pump actuates a switch 70 or device 76 to pulse a step counter 60 having a rotatable member carrying a magnet 62 co-operating with reed switches 64, 66. Immediately credit is established, switch 66 opens to bias gate 108 whereby semi-conductor switch 110 conducts to energize relay 114 closing contacts 148, 150 in the circuit of solenoid valve 146, contacts 152, 154 in the circuit of pump motor 144, contacts 116, 118 energizing reset motor 120, and contacts 140, 142 in series with hold-on contacts 136, 138 of a relay 92. Switch 96 is closed by the reset motor when the pump is switched on to energize relay 98 to close contacts 126, 128 energizing relay 92, contacts 166, 168 preparing a debiting circuit 162, and contacts 122, 124 connecting a pulsing switch 50, associated with the pump, with counter 42. Relay 92 closes contacts 132, 134 and opens contacts 130, 132 to change over the step counter 60 from addition to subtraction, closes contacts 136, 138 maintaining the supply to relay 92, opens normally closed contacts 88, 90 to de-energize coil 72 whereby insertion of further coins and bank-notes is prevented and closes contacts 88, 164 to supply power to the debiting circuit. Counter 42 includes a rotatable member carrying magnets 44, 46 co-operating with reed switches 52, 54 and 56. Switch 56 debits the step counter 60 by one unit on each actuation. When credit is nearly exhausted, switches 66 and 52 are both closed to short out semi-conductor gate 148 and deenergize solenoid coil 146 reducing the flow, until switch 54 closes to short out semi-conductor gate 110 de-energizing relay 114 and stopping motor 144. If the customer replaces the fluid nozzle while credit remains, switch 96 is opened, relay 98 is de-energized and power is supplied to the debiting circuit through contacts 88, 164 of relay 92 and contacts 166, 168 of relay 98, the debiting circuit using a relaxation oscillator of conventional design. The counter is counted down to zero at a faster rate than normal to penalize the user and prevent fraudulent operation of the petrol pump. Reed switch 64 closes when the maximum amount of credit has been established to de-energize coil 72 and prevent insertion of further coins and banknotes. Time switch 184 opens the circuit of the pump if dispensing is not completed within a predetermined time.

The rule 2 carries several scales 5 of viscosity expressed in different units and also three cursors 10, 11, 12. In one use of the apparatus, two of the cursors are set against the scales 5 according to the known viscosities of a liquid at two temperatures and the viscosity at a third temperature is found by adjusting the rule until the set cursors coincide at the reading line with the corresponding temperature curves and then reading the desired one of the scales 5 by means of the third cursor over the curve corresponding to the third temperature. Supplementary systems of curves 14, 15 corresponding to the index of viscosity VI and to the S.A.E. classification index may be read through a window 16 in the rule 2. In a different arrangement, Fig. 2, the viscosity scales 5 are marked on a disc 2 rotatable, together with cursor arms 10, 11, 12 about a pivot 3 slidable in a slot 17 formed in a base 1 bearing the system of curves 13. A fixed reference mark 16 co-operates with an additional system of curves 14. The areas between the curves may be differently coloured to facilitate reading. A system of curves 18 may be used with the cursors 10, 11, 12 to determine the percentage composition of a mixture of two oils of known viscosities having a required viscosity. The disc 2 may be guided by side flanges of the base 1 instead of by the slot 17.
