Title: Data storage devices of the magnetic core type
IPC: G11C8/02
Filed: 1954-07-29
Abstract: 754,393. Circuits employing bi-stable magnetic elements. MAX-PLANCK-GES. ZUR FORDERUNG DER WISSENSCHAFTEN E.V. July 29, 1954 [Aug. 3, 1953], No. 22209/54. Class 40 (4). [Also in Group XIX] Selecting apparatus for a magnetic-core matrix store comprises selection transformers, also arranged as a matrix, each having at least four windings, first and second windings being connected respectively in series by rows and columns to selection-pulse leads, third windings being passed by a sustained direct-current sufficient to restore a reversed transformer at the end of the selection pulses, and fourth windings individually supplying output signals to select corresponding rows of the storage matrix. For a two-dimensional matrix store comprising sixteen rows of cores 7, Fig. 3, sixteen selection transformers are arranged in a square matrix and have their row and column windings connected to corresponding row switch tubes 8 and column switch tubes 9. The output windings 5 are connected to respective rows of windings on the store cores 7. Windings 4 are passed by a direct-current which normally maintains each selection transformer in a state P, Fig. 2. When one each of the tubes 8, 9 produces a pulse, a corresponding transformer is reversed and produces in its winding 5 a pulse which will restore any reversed cores in the selected row of the store matrix to produce pulses in their column windings. As the pulses produced by the tubes 8, 9 cease, the reversed transformer is restored by the direct-current winding and produces a pulse in the corresponding row of windings in the store. If the column windings of any of the cores are also pulsed at this time, the state of those cores will be reversed. The transformers may be so arranged that the writing-in pulses are appropriately smaller than the readout pulses, unless the storage cores also have biasing direct-current windings. The pulses produced by the tubes 8, 9 are maintained constant by limiting diodes 10 connected to their control grids and by the negative-feedback action of cathode resistances. For a threedimensional matrix store, Fig. 5, two matrices 26, 31 of selection transformers are used to select a row and a column in each digit-place plane. The output winding of each transformer is connected in series with all of the core windings of the corresponding row or column in all of the digit-place planes. A third read-out and writing-in winding on each core is connected in series with corresponding windings in the same digit-place plane. Regenerating arrangements (see Group XIX) also are described.

Abstract: 619,881. Potato harvesters. MOFFAT, A. A. July 25, 1947, No. 22229/46. [Class 6 (iii)] [Also in Group XXX] A potato harvester comprises the combination of a rotary haulm cutter, consisting of at least one pair of movable jaws 2 mounted on a spindle 3 in front of a cutting blade 12 which cooperates with a fixed ledger blade 13, the jaws being connected to a cam follower 7 spring urged 8 against a fixed cam plate 9, a haulm engaging fork 14 beneath said ledger blade, a plough 15, a rotatable tined spinner 16 with its axis longitudinal of the harvester and the path of the tines behind the forward edge of the plough, and an elevator consisting of an. endless band with teeth 25 and a wire cage enclosing its lower run, both the cutter and elevator being actuated by the ground wheels 34. The jaws 2 are pivoted at 2A and are reciprocated by lobes 10 on the cam plate 9 moving tappets 11 which abut against the arms. In operation, the haulms are gripped by the jaws when the latter near the tork and rotation of the blade 12 cuts off haulms against the blade 13. After the jaws have passed this point they open and release haulms due to the springs 2B and the position of the lobes 10 which are arranged to close the jaws in the vicinity of the fork and then open them after they have passed the ledger blade. The potatoes are raised in a subsequent operation as the digger and cutting mechanisms are offset with respect to each other. Potatoes raised by the plough 15 are swept into a cage 23 by the spinner 16 and transferred by conveyer to the elevator. Earth and small objects are sifted out through cage 23 and the elevator, and any remaining stones are separated when the mixture is subjected to an air blast through a gap in a shoot at the top of the elevator, stones falling through while potatoes are sustained.

Patent GB-225112-A (GB)
Abstract: 225,112. Fairweather, H. G. C., (Whittemore. Hulbert, Whittemore, & Belknap). March 31, 1924. Cleaning, fluid-pressure processes for.-Relates to boiler cleaners of the type wherein an intermeshing worm and worm wheel operate the valve and the blower element respectively. The tendency of the valve to close before the blower element has come to rest is overcome bv the application of an unbalanced force applied positively to the valve stem in such a way as to tend to open the valve first and to maintain it in open position. A piston 18, Fig. 2, carrying the valve 8 is connected to the worm shaft 6. On rotation of the shaft, the steam &c. under pressure, acting on the valve 8 and on the piston 18, tends to move the shaft 6 longitudinally until the worm 5 comes up against the casing 7, after which the worm wheel 4 begins rotation and the blower element is operated. When the operation is finished, the pressure on the piston 18 maintains. the valve open until the blower element has been operated and a pin 17 on the warm wheel 4 engages a lug 16 on the casing 7, when the worm wheel is held stationary and the valve closes. According to Fig. 5, the valve stem 27 is threaded in a pinion 31 in gear with toothed wheels 32, which are mounted on the blower element 25 and are in gear with the internal gear 33. On rotation of the valve stem, the valve 26 opens, the stem moving relatively to the pinion 31 until a stop 35 engages the pinion which then begins rotation and through gears 32, 33 rotates the blower element 25. When the valve stem 27 is rotated in the opposite direction, the pressure of steam &c. on the piston 34 delays the closing of the valve until the blowing element has been operated. Instead of a piston and steam pressure, a spring or a weighted lever may be used positively to maintain the valve open until the blower element has been operated.

Abstract: 914,121. Testing cable insulation. TELEGRAPH CONSTRUCTION & MAINTENANCE CO. Ltd. July 14, 1959 [July 14, 1958], No. 22548/58. Class 37. A method of testing the insulation of polythene insulated cables comprises drawing the cable through a tubular electrode maintained at a high voltage and having liquid chlorinated hydrocarbon circulated through it. As shown, the cable C is passed through a bath 5 containing the tubular electrode 10 through which carbon tetrachloride is circulated by means of a pump 6 and a filter 8. Alternatively trichlorethylene, chloroform, tetrachlorethane or hexachlorethane may be used. The bath 5 is supported by an insulator 12. The centre conductor is connected via a slip-ring on the take-up reel 13 to a highvoltage transformer 15, whilst the electrode 10 is connected to the transformer via a highfrequency blocking circuit 16. Whenever a void in the insulation passes through the tubular electrode 10, the air within is ionized, resulting in the production of a high-frequency oscillation which is amplified and displayed on a cathoderay oscilloscope. In an alternative arrangement the bath 5 is dispensed with and the cable is passed through seals at each end of the tubular electrode 10. Specification 782,290 is referred to.
