Abstract: 1,176,964. Image pick-up tubes. RCA CORP. 10 Aug., 1967 [20 Dec., 1966], No. 36870/67. Heading H1D. A vidicon is provided with two cathodes 44 and 46, Fig. 2, one cathode 44 producing a narrow (1 mil.) scanning beam and the other cathode 46 producing a broad (30 mils.) beam operative on the flyback of the scanning beam to discharge the target electrode. When the target is scanned from bottom to top, the scanning beam and cathode are arranged above the discharge beam and cathode, and both beams are arranged to be tangential to a magnetic flux line 52 or 62; this can be achieved by means of an auxiliary coil (40, Fig. 1, not shown) arranged outside the tube around the electron gun and connected in series with the focusing coil (32), the magnetic field of the auxiliary coil being adjusted by varying the current through it until the required tangential flux is provided. Each cathode comprises a cylinder arranged in a ceramic disc 54 and provided with an inclined end face covered with an emissive coating; and each cathode has its own lead-in connection 56 or 64. The control electrode 72 has individual apertures 76 and 78 for the respective beams, the aperture 78 being crossed by grid wires to preserve a uniform current density in the broad discharge beam, and a depending shield 82 prevents electron flow from one cathode to the other when the two are at different potentials. A second electrode 84 is similarly provided with grid wires across its aperture 92, and the electron gun is completed by a limiting aperture plate 96. If the scanning beam has a diameter of 1 mil. and the discharging beam a diameter of 30 mils., the discharging beam should preferably be disposed 50 mils. below the scanning beam on the target; if the magnification of the electron optics is one half, there should then be a spacing of 100 mils. between the apertures 100 and 102 in the plate 96.

Title: Improvements in or relating to resilient calender bowls
IPC: F16C29/00
Filed: 1957-12-03
Abstract: 862,800. Rollers. DORNBUSCH, P., [trading as DORNBUSCH & CO.]. Dec. 3, 1957 [Dec. 7, 1956 (2)], No. 37587/57. Class 42(2). A calender bowl comprising a rigid core and a resilient jacket of paper, fibre fleece, fabric or the like, is made by spirally winding on to the core at least one strip of the resilient material, applying a binding-agent to the strip, preferably prior to winding it, and applying external pressure to the wound strip in a direction at right-angles to the surface of the strip. According to one method disclosed in the Specification, the jacket 4 comprises strips of material wound spirally on to the core 1 with their surfaces extending axially of the core, and pressure is applied by surrounding the jacket with a helically wound hose 7, encasing the whole in a rigid sleeve 8 and filling the hose with a fluid. Depending on the nature of the binding agent used, it may be advantageous to heat the fluid. Alternatively, the jacket may comprise strips of material having one straight edge and one serrated edge, wound on to the core 1 in the form of spirals 13 with their serrations pointing inwardly towards the core. In this case, pressure is exerted on the windings by means of a displaceable collar 3, and after compressing the windings, the collar is held against the jacket by a washer 6 and nut 5. The binding-agent used in this instance enters the gaps formed between the serrations of the winding strip and the core, and will firmly cement the jacket to the core.

Abstract: 1506764 Active delays DEFENCE SECRETARY OF STATE FOR 10 Sept 1976 [12 Sept 1975] 37666/75 Heading H3U A clocked delay line includes: a first input stage comprising at least one analogue storage cell 1 receiving signal samples at an input 2 and producing output samples, having a lower sampling rate, at a plurality of outputs 3; at least one further input stage comprising a plurality of analogue storage cells 11, 21, 31 corresponding in number to the number of outputs of the first input stage and each producing a plurality of outputs 13, 23, 33 at a lower sampling frequency; at least one precursory output stage comprising a plurality of analogue storage cells 14, 24, 34 each having a plurality of inputs 16, 26, 36 receiving signal samples from respective preceding stages and each having an output at which is produced a recombined sample series at a higher sampling rate; and a final output stage comprising at least one analogue store 4 having a plurality of inputs 6 receiving signal samples from respective outputs of the precursory output stages and having an output at which is produced a recombined sample series at a higher sampling rate. As shown, signal samples are fed serially into a first shift register 1 at a rate f, and are fed out in parallel at a rate f/3 to provide three serial input signals to respective second stage shift registers 11, 21, 31 which in turn produce nine parallel outputs at a rate f/9 to delays 17, 27, 37 each of which comprises a respective two stage delay for each of the nine signals. The delayed signals are then fed in parallel at a clock rate f/9 to registers 14, 24, 34 each of which produces a serial output at clock rate f/3. These outputs are then fed as parallel inputs of a final stage 4 having a serial output at the initial clock rate f. The arrangement is equivalent to a simple delay of thirty four stages, but comprises only ten transfer locations. The series may be extended to give increased delays, Fig. 5 (not shown). In a modification, Fig. 6 (not shown), instead of the three-location shift registers two-location registers are used, every third sample being passed on directly to the next stage without entering the register, by modifying the clock signal sequence. In a second embodiment, Fig. 8 (not shown), multipart delays, e.g. CCD or Bucket Brigade, are used. In the inputs stages these delays have a single input and two outputs so that each succeeding stage doubles the number of signal paths. Conversely each output stage delay has two inputs and a single output.
