Title: Magnetic core converter and storage unit
IPC: H03M7/12
Filed: 1954-05-25
Abstract: 746,724. Electric digital-data-storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 25,1954 [May 28, 1953], No. 15366/54. Class 106 (1). A code converter for converting differentially timed impulses in one code to differentially timed impulses in a second code comprises an input means and a storage matrix which cooperate to effect the conversion, and an output means. As described, the first code is the usual punch card " 1 2 3 ... 7 8 9 " code and the second code a " 1 2 4 8 " code. Data represented by perforations in a card in the usual manner is read to produce differentially timed pulses which are applied to the column windings 12 of a 6 x 80 matrix of saturable magnetic cores, each column corresponding to one column of the card, and the row windings 11 of the matrix are so pulsed by mechanically controlled cam contacts 25-30 that as row nine of the card is being sensed rows " 1 " and " 8 " of the matrix are pulsed, as row eight is being sensed row " 8 is pulsed, as row seven is being sensed row " 1," " 2 " and " 4 " are pulsed and so on. Thus each digit on the card is stored in a " 1 2 4 8 " code in the first four rows of the matrix, the remaining two rows being for alphabetical characters. The matrix is then read by successively pulsing the rows to produce differentially timed output pulses in a " 1 2 4 8 " code on column windings 12, which pulses are used to control the punching of an " increased capacity card," Fig. 2, the upper and lower decks of which are each equivalent in storage capacity, but in a " 1 2 4 8 " code, to a normal card. The current flowing in any particular column winding as a result of an induced output pulse caused by the application of a " read out " pulse to a particular row is in the same direction as the " read-in " current and its duration of flow is prolonged by the action of an associated thyratron having its cathode-toanode circuit in parallel with the column winding, so that by applying a second row pulse in a " read-in " direction immediately after the " read-out " pulse and before the output current has died away, the data read from the row is immediately re-recorded, and thus repeated reading out is possible.

Title: Improvements in or relating to arc welders
IPC: B23K9/067
Filed: 1966-04-12
Abstract: 1,123,096. Welding by fusion. DYNATECH CORP. 12 April, 1966 [8 April, 1965], No. 16003/66. Heading B3R. [Also in Division H2] In an arc welding device, the welding arc is initiated by a pilot arc struck when a starting electrode 45 is moved out of contact with the welding electrode 37. A pistol-like work-holder having manually releasable spring-loaded jaws 21, 22 with conducting ends 23, 24 for gripping a pair of thermo-couple wires C to be welded, is insertable in a conductive apertured cup 51 secured in the easing 12 of an arc welder 11. The cup 51 has an insulating cover 54. With the holder inserted, the work C is correctly spaced from a tungsten electrode 37 secured in a split collet 39 in an insulating sleeve 32 mounted within the casing 12. Argon fed from a pipe 42 through nozzle 36 exits around the work C and through apertures 43 in the sleeve 32 and assists in transferring a pilot arc struck between the starting electrode 45 and the welding electrode 37. The main arc is connected across the output of rectifier 85 in series with an inductance 86 and resistors 87, 88 and in parallel with a capacitor 89. Actuation of switch 17 energizes the argon control valve 67 and a time delay relay 74 which eventually operates relay 78 to switch on the welding current. Current flows through the main and starting electrodes 37, 45 and the resultant voltage across resistor 87 energizes a spring-loaded solenoid to withdraw the starting electrode. Should a pilot arc fail to strike the starting electrode 45 is returned and again withdrawn. When the main arc strikes the increased volt drop across resistor 87 energizes a slow to actuate relay 76 whose operation releases relay 78 and disconnects the welding current. Return of the starting electrode short circuits capacitor 89. The switch 17 may be actuated by insertion of the work-holder in the cup 51.

Abstract: 1,088,514. Radar. SOUTH AFRICAN INVENTIONS DEVELOPMENT CORPORATION. April 14, 1965 [April 20, 1964], No. 16046/65. Heading H4D. In order to measure the range of a station B at a station A, the stations transmit electromagnetic waves of respective frequencies f A , # B , # A  ~# B  being a relatively low frequency, station B forms a signal of frequency # A  ~# B  and compares it with the output of a local reference oscillator f RB  of high stability to produce a control signal acting on frequency # B  to establish a predetermined phase and frequency relationship between signals # A ~# B  and # RB , and at station A a signal of frequency # A  ~# B  is derived and compared in phase with a reference signal of frequency # RA  nominally the same as # RB . The transmission of signal frequency# A  ~# B  from B to A, as in Specification 811,762, is thereby avoided. In the embodiment # RB  = # A  ~# B ; signals # A ,# B  are radiated by frequency modulation; a choice of frequencies # A .# B  is available; light waves may be employed; the range measurement is effected by a phase shifter and zero-centre meter; and # A  ~# B  is 1000 c/s. The reference signal oscillators may be phase-locked by transmission of one reference signal to the other station prior to measurement.

Title: Improvements in or relating to electric follow-up systems
Inventor: ALLEN NIGEL ROBERT
IPC: G05D3/14
Filed: 1954-05-31
Abstract: 776,868. Electric control systems. TEDDING- TON INDUSTRIAL EQUIPMENT, Ltd. May 11, 1955 [May 31, 1954], No. 16109/54. Class 40 (1). In an electric follow-up system wherein a motor is controlled by controlling and followup potentiometers maintained in correspondence, imperfect control, caused by poor connections between the wiper and the track of the follow-up potentiometer, is avoided by the provision of fixed potentiometers bridged across the faulty potentiometer to maintain the continuity of the circuit. A controlling potentiometer 1 having an arm 5 is controlled automatically by a temperature responsive device 4, and it is coupled in a circuit comprising a transformer 7 and relays 8 and 9 to a second potentiometer 2 having an arm 13 operated by a reversible electric motor 6. The relays 8 and 9 act in opposition on a movable contact 10 and any movement of arm 5 will unbalance the circuit and cause motor 6 to operate a valve or other device to meet the change in conditions registered at 4 and to move follow-up arm 13 until balance in the circuit is restored. Potentiometers 18, 19 are connected across potentiometer 2 so that in the event of a faulty contact between arm 13 and potentiometer 2 the continuity of the circuit will be maintained. Thus movement of arm 5 will cause motor 6 to operate in one direction or the other up to the limit set by one of limit switches 14, 15. This excessive movement will cause a change in external conditions with resulting movement of arm 5 in the opposite direction and movement of the motor up to the position set by the other limit switch. Hence the control will operate as an "on-off" control instead of providing modulation until potentiometer 2 is cleared of contamination by the action of traversing wiper 13. Secondary resistances 20 and 21 can be fitted across the potentiometer 1 to provide a balanced bridge system as is provided by the original circuit.

Title: Improvements relating to the preparation of coal-oil slurries
IPC: C10L1/32
Filed: 1962-04-27
Abstract: A process for preparing a coal-oil slurry comprises mixing the coal with the oil, passing the mixture to a flash zone maintained at a pressure below that of the mixing zone, and recovering a coal-oil slurry of reduced water content.  The coal and oil may be mixed at a temperature between 90 DEG  and 150 DEG  C., or 80-100 DEG  C. if the flash zone is maintained under a partial vacuum, e.g. 10-27 inches Hg, which is preferred.  The slurry may be removed from the flash zone by means of a barometric leg or pump, and the water vapour from this zone may be condensed, and treated in an oil-water separator to separate any oil which may have passed over.  Preferably, the coal particles are sized 1/8 inch or less.  The slurry may be used in a blast furnace (see Division C7).ALSO:Coal-oil slurries prepared by mixing coal and oil, passing the mixture to a flash zone maintained at a pressure below that of the mixing zone, and recovering a coal-oil slurry of reduced water content (for details see Division C5) are used for firing blast furnaces. The slurry may be injected into the blast-pipe connecting the tuyere and the air main, and the coal particles are preferably sized 1/8 inch or less to allow the injection of the slurry into the blast-pipe to be at a point as close as possible to the tuyere.
