Filed: 1973-11-15
Abstract: 1428570 Memory system HONEYWELL INFORMATION SYSTEMS Inc 15 Nov 1973 [15 Nov 1972] 52969/73 Heading G4A A memory system having error checking and correcting circuitry includes a timing circuit for generating a memory busy signal of one length for a full write operation and of a greater length for a partial write operation. As described data comprising bytes each with a parity bit, fed from a central processing unit 5 (Fig. 1) to a register 20 in the memory module 6 is transferred to (1) OR circuits 25 feeding an error correcting encoder 34 deriving check bits which are fed via check bit corrector 37 to memory array 40, (2) OR circuits 26 which feed the data bits to the memory and (3) parity check circuit 21 which derives the parity of the data bytes and compares them with the received parity bits, a signal being fed to the processor in the case of error. The major part of the write operation (which is of length 800 ns.) is taken up with calculating the check digits. Data read from the memory is fed to decoder 45 which recomputes the check bits and compares with stored check bits to signal, in the case of an error, timing circuit 55. Error locator and correction circuit 50 calculates the bits causing the discrepancy and feeds the corrected data and parity bits (computed by decoder 45) to the register 20. The major part of the read operation is similarly taken up with calculating the corrected data bits and parity bits, the read operation also being of 800 ns. Mask signals from the CPU are fed to the OR circuits and check bit corrector 37. In a partial write operation, data bytes to be retained are selected from the memory array 40 by OR circuits 25 and fed together with the new bytes to the encoder 35. OR circuits 26 are similarly actuated but since an error may be present in the data read from the memory, decoder 50 is actuated which necessitates extending the cycle to 945 ns. If an error is found the cycle is further extended to 1000 ns. Timing circuit (Fig. 2).-Either a "refresh GO" signal, or its complement together with a "memory GO" signal, results in gate 107 or gate 108 being enabled to apply a signal to a delay line 110, a memory busy signal MBY being generated from OR gate 132 by the output from the 0 output tap of the delay line. After 300 ns. the output from tap 300 disables gates 107, 108 so that a pulse of this length travels along the line. For a read, full write or refresh operation; after 400 ns. the pulse is fed via gate 126 to a further delay line 130 of lenth 100 ns. so that after a total of 800 ns. NOR gate 133 is enabled to terminate the memory busy signal. For a partial write operation a signal RMW is applied to disable gate 126 and prime gates 123, 124 so that in dependence on whether an error signal RE is generated or not, the pulse is fed from the tap 600 or the tap 545 respectively to the second delay line to appropriately lengthen the duration of the memory busy signal.

[Also in Division H3] A bi-stable device comprises an electrical store and a capacitative store operable during first and second consecutive time intervals to transmit a signal from the input to the output of the device. The first storage circuit comprises a pair of inverters 10, 20 forming a flip-flop, the second storage circuit a single inverter 30 and capacitance C33. IGFETs are used throughout. As applied to shift registers a clock pulse CP is applied to lead 83 and its inverse to lead 84 with time intervals T1, T2 (Fig. 2, not shown) which are not related. Transmission gate 40 couples or decouples input source 86 to or from input capacitance node 13 of inverter 10 according to whether CP is at 0 or + V 0 . Gates 50, 60 are controlled by CP in the opposite sense to 40 to couple or decouple node 13 to node 24, and the latter to input capacitor node 33 of inverter 30, respectively. If flip-flop 10, 20 is initially in the state of 12, 21 on and 11, 22 off, so that nodes 14, 24, 33 are respectively at 0, + V 0 , 0, and output capacitance C L  is charged to +V 0 , then while 86 is at + V 0  the clock pulses CP, CP open and close gates 40, 50, 60 without effect. When 86 charges to 0, however, the next T1 interval causes capacitance node 13 to discharge to 0 via gate 40 and source 86. Inverter 10 changes state, node 14 charges to + V 0  and inverter 20 changes state. In the following T2 interval gate 40 turns off, 50 and 60 on. Gate 50 locks flip-flop 10, 20 and gate 60 transfers the state of node 14 to input capacitance node 33 which charges to + V 0 . Inverter 30 reverses to discharge C L  to 0.

If both syndrome digits S 1  and S 2  are non-zero, the ith data digit is in error where and its corrected value is If only one of S 1  or S 2  is non-zero, the error is in one of the check digits C 1 , C 2 , whereas if S 1  and S 2  are both zero there is no error. In a generalization, there maybe more or less than 10 data digits N i  and the number 11 is then replaced by a prime number greater than the number of data digits. The syndrome digits S 1 , S 2  are formed by a modulo 11 adder 16 via registers 12, 14, gates 19, 21 and a binary counter 20 (for repeated addition). The syndrome digits S 1 , S 2  are stored in a register 18, whence S 1 <SP>-1</SP> and S 2  are formed in decimal form by an inverse decoder 22 and a decoder 24 respectively, the circuit of inverse decoder 22 being given in Fig. 8 (not shown). Each decoder produces a decimal output on one of lines 1-10, the two outputs being fed to an array multiplier 26 to form S 1 <SP>-1</SP>S 2  (mod 11). The array multiplier 26, Fig. 6, comprises a square grid of wires 1-10 by 1-10, outputs being fed from all the crosspoints of the grid to ten OR gates 42a-42j. The inputs of, say, OR gate 42a, which leads to a 1 output of the array multiplier, originate from all those crosspoints (x, y), i.e. (1, 1), (2, 6), (3, 4), ... (10, 10), where xy#1 (mod 11). The decimal output i of the array multiplier 26 is stored in a register 28, whence it is used at the appropriate time as a disabling signal to block the data digit N i  when the data string is being read-out of register 10 via an AND gate 34. The value - S 1  formed by a complementer 30 is then added to N i  and the result conveyed to the output via an AND gate 36. The circuit of the complementer 30 is given in Fig. 9 (not shown). The Specification also discloses a method of correcting two data digits when their positions in a data string are known. The label may be marked with a bar code and may be optically scanned.

Abstract: 1,211,787. Hydrostatic transmission. DANFOSS A.S. 12 Nov., 1968 [14 Dec., 1967], No. 53489/68. Heading F2D. In a reversible hydrostatic vehicle transmission comprising two motors 1, 2 driving wheels 3 and driven by pump 4 through a reversing and throttle valve 6, the motors 1 and 2 are selectively connected in series or parallel, and their relative speeds are controlled for steering, by five throttle valves 16-20 connected in the main delivery and return lines 9, 10 and in lines 21, 22 connecting opposite sides of the motors. Parallel operation. - Straight - ahead travel with the motors 1 and 2 in parallel is achieved by closing valve 20 and opening valves 16-19. For a left- or right-hand turn, either pair 16, 18 or 17, 19 of valves is actuated simultaneously in the direction of closing to slow down their respective motor. Series operation.-Straight-ahead travel with the motors 1 and 2 in series is achieved by closing valves 16 and 19, and opening valves 17, 18 and 20. Partial closure of valves 17 and 20, and simultaneous partial opening of valve 16, slows down motor 2 for turning. Similarly motor 1 may be slowed down by partially closing valves 18 and 20 and partially opening valve 19. In Figs. 2-4 (not shown), throttle valves 18, 19 are formed as a spool (43) in a bore axially opposite a second spool (44) forming valves 16, 17, both spools being spring-biased towards a central control shaft (25). A third spool (34) in a third bore at right angles to spools (43), (44) and axially displaced along the shaft (25) which carries two cams against which the spools abut. The shaft is axially displaceable to control the valves for series or parallel operation, and is rotatable for steering the vehicle. A spring biased stop (62) positions the shaft axially.
