Title: Circuit for controlling the brightness of the scanning spot in a cathode ray tube
IPC: H04N3/20
Filed: 1970-05-22
Abstract: 1311763 Function generators IWATSU ELECTRIC CO Ltd 22 May 1970 [16 June 1969 1 Aug 1969] 24878/70 Heading G4G [Also in Division H4] In an arrangement for controlling the intensity of the beam of a cathode-ray tube as a function of the scanning velocity in order to produce constant brightness independently of such velocity, voltages VLx and VLy (see Fig. 2) proportional respectively to the voltages developed across the X and Y deflection coils Lx, Ly are derived in circuits 2, 3 (each following the arrangement shown in Fig. 1), squared and added in operational circuit 4 to produce V<SP>2</SP>L and then modified in function generator 5 to produce the function-V L <SP>5</SP>/ 14  which is supplied to the beam intensity modulation grid via an amplifier 6 which is controlled by the beam blanking-unblanking signals. The description includes a mathematical analysis of the parameters of the circuit of Fig. 1 and shows that the output voltage EOαV L  is independent of the voltage developed across the deflection coil L due to the inherent resistance R<SP>1</SP> of the coil. Also the considerations leading to the production of the control function V L <SP>5</SP>/ 14  are set out. Circuit details of the X portion of the operational circuit 4 and of the function generator 5 are given with reference to Fig. 3 and to Figs. 4A and 4B respectively (not shown). The arrangement of Fig. 1 may be utilized to control the production of beam unblanking pulses so that in the event of failure of scanning the beam remains blanked and the tube screen phosphor is not damaged. Fig. 5 shows the scheme in which circuits 9 and 10 produce constant amplitude pulses from the positively and the negatively going portions, respectively, of the output EO of the amplifier 1 (a similar arrangement being employed for the -Y deflection circuitry) such pulses being supplied via OR gate 11 to a holding circuit 12 from which after shaping they are supplied via gate 13 to the CRT intensity modulation amplifier as beam unblanking pulses. When the DC resistance of the deflection coils is negligible the operational amplifiers may be replaced by a simplier circuit arrangement (Fig. 7, not shown).

Abstract: 702,392. Mixing-appliances. CROFT, C. T. Oct. 17, 1951 [Oct. 17, 1950], No. 25239/50. Class 86 [Also in Group XXVIII] In a mixing machine comprising a stationary enclosed mixing vessel containing a plurality of paddles which co-operate with the floor of the vessel in the mixing action, mounted for rotation in a fixed path about a vertical axis and simultaneously revolvable about substantially horizontal axes the two movements being effected by differential gearing, the differential gearing is controlled by clutch means which is engageable to cause the paddles to traverse a rotational path about the vertical axis with a sweeping action with respect to the floor of the vessel. A mixer suitable for mixing the ingredients of asbestos lagging comprises a circular vessel 1 with a lid 2 having a charging opening 3. A tubular shaft 13 driven by a worm 15 through a worm wheel 14, extends centrally through the lid and carries a cage 5 which bears four horizontal radial shafts 8 having paddles 9. Bevel pinions 11 on the shafts 8 engage a bevel pinion 28 rotatable with a shaft 20 extending coaxially through the shaft 13. The shaft 20 is vertically displacable, by means of a piston and cylinder 25, 26, to either of two positions in which a friction disc clutch member 21 thereon engages either a clutch disc 22 fixed to the frame of the machine, or a clutch disc 18 on the shaft 13. For a mixing operation the clutch discs 21, 22 are engaged to hold the shaft 20 against rotation. The gears 11, 28 then cause the shafts 8 to rotate axially as they revolve about a vertical axis. A closable discharge opening is provided in the base of the vessel and to discharge the vessel the clutch discs 18, 21 are engaged so that shafts 13, 20 have no relative movement. The shafts 8 then remain stationary about their axes whilst revolving about a vertical axis so that the paddles sweep the material out of the discharge opening. Material is fed into the charging opening 3 by a screw conveyer 42 which is in turn fed from a loading box 39. The loading box 39, Fig. 3; includes a pair of airlock flaps 48 and a door 51 hinged on a horizontal axis and adapted, when open, to form a loading platform for a sack of asbestos fibres or other material to be charged into the mixer. The flaps 48 may be operated by a handle 48a, Fig. 1, but are preferably operated in synchronism with the door 51 by a lever and linkage mechanism, Fig. 3, which causes the flaps 48 to open when the door is closed, and vice versa. Means are provided so that the sack may be suspended within the box 39 from wires passing through holes 64. By operating the wires the sack may be shaken vertically. Push rods 66 extending into the box 39 carry plates 69 adapted to engage' the sides of the hanging sack to facilitate its discharge. Liquid to be mixed with the material in the mixer may be introduced at a suitable point or points in the top or side of the vessel by means of piping 35.
