Abstract: A signal modulation system in which clock signals can be modulated with first and second modulation signals which are applied to the clock signals through first and second switching circuits. A control means involving threshold devices is so responsive to the operation of the switching circuits that at any one time only one of the switching circuits is able to pass modulation signals to the clock signals.

Abstract: A method of making a magnetic recording and reproducing component includes, providing in a ferrite member a plurality of grooves defining side-by-side Vee shaped ridges which are reinforced by filling the grooves wwth non-magnetic material. The each ridge apex is then machined to expose a ferrite surface and is bonded to a second ferrite member by means of non-magnetic material so that each face is separated from the second ferrite member by a gap filled with non-magnetic material. A third member is preferably bonded to the second member to produce a second gap aligning with the first gap. Cutting the members between the adjacent ridges to provide a corresponding number of separately operable components.

Abstract: A magnetic recording apparatus in which fixed information, which may be an outline of a business form, is recorded as a predetermined pattern on a magnetizable member. A magnetic recording member is separated from the magnetizable member by a screening member which includes a plurality of magnetic elements thereon. The magnetic elements are positioned on a backing layer and selectively prevent the magnetic field produced by the recording means from changing the magnetic state of the magnetizable member so that the predetermined pattern is recorded on the magnetizable member. The screening member may also include further small magnetic materials to increase the number of magnetic fringe fields which will allow a more uniform change of state of areas of the magnetizable member.

Abstract: A STEPPING MOTOR HAS AN EVEN NUMBER OF STATOR POLES AND A TWO POLE ROTOR. A SHIFT REGISTER ENERGIZES STATOR POLE WINDINGS, EACH STAGE OF THE REGISTER BEING CONNECTED TO A PAIR OF DIAMETRICALLY OPPOSED STATOR POLE COILS. THE REGISTER IS PRE-SET TO PRODUCE A STATOR MAGNETIC FIELD PATTERN AND UPON RECEIPT OF SHIFT SIGNALS, THE PATTERN IS STEPPED AROUND THE STATOR. THE STATOR FIELD PATTERN IS SUCH THAT THE ROTOR IS ATTRACTED TO A PARTICULAR POLE WHILE POLES ADAJACENT TO THE PARTICULAR POLE AND ON EITHER SIDE THEREOF PRODUCE REPULSIVE FIELSS AIDING IN RETAINING THE ROTOR IN ALIGNMENT WITH THE PARTICULAR POLE. A SHIFT SIGNAL STEPS THE STATOR FIELD PATTERN SUCH THAT THE ADJACENT POLE IN THE DIRECTION OF ROTATION PRODUCES AND ATTRACTIVE FIELD TENDING TO ALIGN THE ROTOR THEREWITH WHILE THE PARTICULAR POLE AND OTHER ADJACENT POLE PRODUCE REPULSIVE FORCES ALSO TENDING TO STEP THE ROTOR BY INCREASING THE TORQUE APPLIED TO THE ROTOR. THE STATOR IS PRODUCED BY BUILDING A STACK OF STARSHAPED LAMINATIONS, ASSEMBLING THE STACK WITH COILS ON EACH LEG INTO A CYLINDRICAL CASE, SETTING THE WHOLE IN POTTING COMPOUND AND BORING OUT THE CENTRE OF THE LAMINATIONS TO LEAVE INDEPENDENT POLES.

Abstract: A data processor is described particularly suited to provide a universal link between a peripheral mechanism and a central computer. The arrangement provides, in addition to an input selection and masking unit and a selective masking output unit, a processing unit for performing logic operations on input information relating to, e.g., incoming and status signals relating to the associated peripheral mechanism in order to derive an output signal pattern for controlling the actuation of the peripheral. In order to carry out a program of stored instructions, each of which specifies a function to be performed, it is frequently necessary that data resulting from the performance of preceding functions is required to undergo processing, for example, comparison with, or modification in the light of, a second item of data. A double set of registers is provided and the processing unit is able, under control of some functional instructions to address a single register in each set so that the contents of both addressed registers are rendered available concurrently on a single program step. There is also provision for using one of the specified addresses as the destination for the result of the prescribed function.

Abstract: A SIGNAL DISTRIBUTION SYSTEM FOR APPLYING SIGNALS TO A DEVICE UNDER TEST IS DESCRIBED. AN INPUT SIGNAL IS APPLIED TO A CENTRE POINT OF A FIRST GROUP OF FOUR RELAYS ON A SUBSTRATE. THE GROUP OF RELAYS ARE ARRAGED SO THAT THE INPUT SIGNAL MAY BE SWITCHED TO ONE OF FOUR SIMILAR GROUPS OF RELAYS SO THAT THE INPUT SIGNAL MAY THEREFORE BE SWITCHED BY OPERATION OF THE APPROPRIATE RELAYS TO ONE OF SIXTEEN OUTPUTS. THE OVERALL TRANSMISSION PATH LENGTHS FROM THE INPUT POINT TO EACH OUTPUT ARE EQUAL TO THUS PROVIDE ALL THE PATHS WITH THE SAME ELECTRICAL CHARACTERISTICS. FURTHER SIMILAR SUBSTRATES MAY BE SPACED FROM THE FIRST SUBSTRATE AND IN THIS CASE A COMMON OUTPUT CHANNEL FOR ALL SUBSTRATES MAY BE PROVIDED ON A CONNECTING PLANE.

Abstract: A visual display device is described for drawing lines on the face of a cathode ray tube. Information describing the lines to be drawn is held in a store and is presented in the form of positional information describing one end (the initial end) of a line together with values representing the displacement from the initial end of the terminal end of the line. By relative shifting operations on this information a standardised line drawing speed is achieved by the repeated cyclic addition of the shifted displacement values into a register holding the positional and displacement information. Other relative shifting of positional and displacement information permits effective speeding up of ''''drawing'''' any part of a line that disappears off the field of view of the cathode ray tube and the shifting of both position and displacement values enables the scale of the drawn display to be altered.
