Title: Improvements connected with the feed control of batch weighing apparatus
Inventor: CHILTON JOHN MOORHOUSE
IPC: G01G13/28
Filed: 1957-11-05
Abstract: 848,644. Weighing-apparatus; programmed control systems. AVERY Ltd., W. & T. Nov. 4, 1958 [Nov. 5, 1957], No. 34420/57. Classes 38 (6) and 40 (1). The feed of material to a batch weighing apparatus is controlled by a relay which also operates a multi-stage Kelvin-Varley potentiometer as in Specification 847,917, and means are provided for setting each stage of the potentiometer to a predetermined value, e.g. by manually-selected switches, electromechanical devices reading punched tape or cards, or telegraphic systems as used in computers. In the Figure the potentiometer circuit is as in Specification 847,917, P1 being controlled by the indicator of the weighing-apparatus and balancing being effected by a three-stage resistor network stepped by relay contacts S1A, S2A and S3A. Switches S5, S6 and S7 are set in accordance with the three digits of the value of weight to be delivered and button PG 1 is pressed. Relay coil S4 is thereby energized to move each of the contacts S4B-S4G to their second positions. Relay S1 is now energized and steps its contacts S1A and S1B until the latter reaches the position corresponding to the setting of S5, when relay RL2 is energized via S4F and breaks the circuit to S1 at R. Closure of S re-energizes S4 via S4B and steps S4B-S4G to their third positions, thus de-energizing RL2 again. The process is now repeated to set S2B and S3B to positions corresponding to the settings of S6 and S7. At the fifth position of S4 contact S4G completes a circuit to connect up the " fast " feed control for the material. P1 will initially be at zero setting in the absence of any material in the weigh hopper and contacts S4D and S4E now complete the bridge connections so that the unbalance voltage operates RL1 to close the feed control circuit at P and start feed of the material. As material is delivered into the hopper P1 eventually reaches a point where the bridge is balanced; the phase of the current through RL1 is now reversed, and contacts P are closed instead of Q. S4 is now energized and steps its contacts to the sixth position to energize RL3 via S4C and change the feed from " fast " to " slow." The point at which this occurs is before the true balance point of the bridge by an amount depending on the magnitude of resistor R35. At the sixth position of S4, however, this resistor is disconnected and the bridge is once more unbalanced. RL1 now closes P again and starts the " slow " feed. At the final balance-point RL1 is de-energized to make contacts Q and step relay S4 to its Seventh position when S4B returns it to its first position; To allow for inertia in the feed system and material in suspension above the hopper the final bridge position is offset by resistors P4 and P5. Different materials can be weighed into the same batch by repeating the operations with S5-S7 set to the sum of the weights of the first two, and so on. The decade system shown can be changed to operate with avoirdupois or other weight system.

Title: Data storage matrix
IPC: G11C11/06
Filed: 1965-08-18
Abstract: 1,058,659. Digital data stores. NATIONAL CASH REGISTER CO. Aug. 18, 1965 [Sept. 28, 1964], No. 35410/65. Heading G4C. A data storage matrix includes a plurality of bi-stable magnetic storage elements 1 connected in a matrix by means of accessing lines. 15 to 18, 5 to 8, 21 to 24, and delay means provided in at least one of the accessing lines in such a manner that a single read pulse applied to a first accessing line reads out information stored in the storage elements coupled to that line and results in a serial sequence of sense signals being obtained from at least one further accessing line coupled to those elements. In one embodiment a read pulse on the Y line, which is coupled serially to all the rows, a delay 12, 13, 14 being inserted in the line joining two adjacent rows, causes parallel read-out of the information stored in row 15, then after a period caused by delay 12, which is a longer period than that of the read-out pulse itself, causes parallel readout on line 16, and then on line 17, etc., thus creating serial read-out on any one of lines 21 to 28. Read-in is accomplished by a pulse on the Y line and appropriate pulses on the X lines at times to correspond with the location of the Y pulse. Read-out information can be fed back in the event of destructive read-out, a read-out pulse being followed by a write-in pulse on line Y. In a second embodiment (Fig. 2, not shown) there are four Y lines and 4 X lines, a single read-out line being used and passing through all the cores, with delays (30 to 32) being situated in the line joining two adjacent columns. A single read pulse on one of the Y lines produces read-out of all the cores connected to that line and the data in passing through the delays emerges in serial form on the read-out line. In a third embodiment (Fig. 3, not shown) four Y lines and eight X lines are described with one read-out line passing through the cores in rows parallel to the X lines with delays (60 to 65) situated between rows. The X lines are situated in two sets of four and the Y lines contain delays (67 to 70) situated between the two sets of X lines. In a fourth embodiment (Fig. 4, not shown) four Y lines are described and one X line and one read-out line, the latter two lines being parallel and threading the cores in columns with delays being situated between the columns. For read-out to occur four spaced X pulses must be applied, and coincident with the fourth pulse a pulse is applied on the appropriate Y line.
