Title: Improvements relating to circuits for protecting the luminescent coatings of cathoderay tubes
IPC: H04N3/20
Filed: 1960-02-19
Abstract: 945,145. Cathode-ray tube circuits. TELEFUNKEN G.m.b.H. Feb. 19, 1960 [Feb. 19, 1959 ; Oct. 30, 1959 (2)], No. 5883/60. Heading H4T. In a cathode-ray tube (C.R.T.) circuit comprising means for operating the C.R.T. to produce a trace on its luminescent screen and including a source of positive voltage for the wall anode of the C.R.T. and means for biasing the other C.R.T. electrodes, the biasing means including a network for biasing one control electrode relative to the cathode, the network is such that, when the circuit is switched-off so as to disable the operating means, two different transient voltages arise at two points of the network and so influence the decay of the bias voltage at the control electrode that such voltage increases momentarily in the sense to increase C.R.T. beam current, or at least decays at a slower rate than that corresponding to the decay of the voltage by which the biasing means is energized; the discharge of the wall anode voltage source is thereby facilitated. All the embodiments relate to television receivers. In one embodiment, Fig. 1, a negative voltage is produced by a diode 18 or by an existing source; when the receiver is switched off the voltage at control grid 10 falls relatively slowly, Fig. 2 (not shown), or if the negative voltage discharge current is made sufficiently high, a brief increase in control grid bias ensues, Fig. 3. In another embodiment, Fig. 5, a resistor 19 is provided to avoid sudden brightness variation resulting from mains voltage fluctuation; after switching-off the receiver the control grid voltage falls slowly as depicted in Fig. 4 (not shown). In a further embodiment, Fig. 6a, the control grid voltage after switching-off the receiver varies as the algebraic sum of curves A, B, Fig. 6b. In a still further embodiment, based on the circuit of Fig. 6a, point 20 is additionally connected to a diode held normally conductive to stabilize the picture brightness against supply voltage fluctuations, Fig. 7 (not shown). In yet another embodiment, Fig. 8, a diode 25 is normally non-conducting ; when the receiver is switchedoff voltage - U B  collapses more rapidly than voltage +U B  and the diode then conducts. The inclusion of a non-linear resistor 23 leads to a reversed sawtooth-like voltage at the control grid, Fig. 9 (not shown). In more embodiments a triode is utilized as a voltage-dependent resistance, Figs. 10, 11 (neither shown).

Abstract: 588,984. Remote supervision systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and BURNS. G. A. March 13, 1945, No. 6216. [Class 40 (i)] In a remote supervision system, particularly concerned with electrical power networks, in which a slave relay adjacent to the supervisory equipment follows the movements of its associated switch, an immediate visual or audible indication is given, if, for any reason, it fails .so to do, by arranging that the circuits for the controlled relay and for the indicating arrangement are completed over contacts of the controlling device and changeover contacts of the relay. As shown, a circuit-breaker AC1 controls a relay M of the type which remains in the position to which it was last set, e.g. as described in Specification 515,529, [Group XXXVII]. Relay M on operating interrupts its energizing circuit and lights a lamp to show the condition of the circuit-breaker. When the positions of the circuit-breaker and the relay are not in agreement, a further relay A, common to several such systems operates a bell. In another arrangement, Fig. 1 (not shown), in which no audible alarm is given, the lamps are controlled over the same contacts as the relay so that when the positions of the latter does not agree with that of the circuitbreaker, both lamps are extinguished.

Abstract: 1441849 Incinerator LOCANER 12 Feb 1974 [16 Feb 1963] 06394/74 Heading F4B A vehicle mounted incinerator comprises a double walled rotary furnace of frusto-conical form surrounded by a casing rotating with the furnace and forming an ash receptacle, a charging device for refuse arranged to prevent the inlet of air, and an exhaust gas outlet leading to an after burner and gas cleaning equipment. Refuse deposited in a hopper 5, Fig. 1, at the rear of the vehicle is fed by a screw 6 into a shoot 3 and a hood surrounding one end of the rotary furnace 1, where it is ignited by burners 19, 20 and burnt with air delivered through the perforated inner wall 16 of the furnace. Ash falling from the end of the drum is moved to the closed end of the ash receptacle 15 by a helical vane 17. Flue gases leaving the hood 2 are burnt by a flame from a burner 62 at the entry to flue conduits 4. A grating 63 - ensures that lightweight refuse burns before being drawn into the flue. The flue 4 leads the gases through a spray 64 to a cyclone 13, having a water reservoir 12 at the bottom and a fan 9 drawing the gases to the outlet 11. A ring main sprays the wall of the cyclone 13, and the gases may be drawn through the water by the action of the fan 9 to pass over the surface according to the level of the overflow. The charging end of the furnace is formed with annular plates co-operating with a stationary member to form a plenum chamber for combustion air supplied in pulsed fashion. The inner and outer walls of the furnace are attached to frame members extending from the mouth of the furnace to the closed end of the ash receptacle so as to allow for thermal expansion, and the inner wall is formed of alternate flat plates and flanged channel members with perforations so as to supply air radially, and in two directions having tangential components (Fig. 3). The charging apparatus, hood 2, flue 4 and gas cleaning equipment can be detached from the remainder of the unit and supported on jacks 74 for maintenance. Ash is removed from the receptacle 15 by reversing the direction of rotation of the furnace, doors 18 being arranged near the discharge end of the furnace, and a door in the hood 2 serves as an inspection door and to admit air to cool the flue gases. The operation of at least one of the burners in the furnace, the burner in the flue and the opening of the inspection door in the charging and flue outlet hood 2 are controlled in accordance with the temperature in the furnace or in the flue.

Abstract: 144,790. Roberts, W. T. B., and British United Shoe Machinery Co. March 15, 1919. Boot-sole sewing-machine; rotary horns.-The horn is so arranged that, while normally free to be rotated about its post, as when operating on a shoe, it may be locked to the post, and when so locked may be rotated to effect an adjustment of the horn mechanism, for instance to vary the height of the horn lip. The invention is described as applied to the horn mechanism of the loosenailing machines described in Specification 1404/93, considered in connexion with Specification 1493/93, [both in Class 89, Nails &c.]. The horn 1, Fig. 1, is secured in a split socket 2 normally free to rotate on a horn post 5 but adapted to be locked to the post by a spring plunger 7,. Fig. 2. The lower end of the post is split by three saw cuts 12, Fig. 8, and is threaded into a split collar 13, Figs. 1 and 3; it is also threaded internally to the same pitch to receive a rod 21, which is connected to the usual horn raising and lowering mechanism of the machine, and carries an adjustable collar against which the usual hornelevating spring boars. A clamp screw 19 serves normally to clamp the collar 13 to the horn post and the post to the rod 2:L. When height adjustment of the horn is desired, the horn is locked to the post by the plunger 7 and the screw 19 is slackened to allow the post to be raised or lowered through the collar 13, which is effected without movement of the rod 21. Specification 105,793, [Class 89 (iii), Nailing &c.], is referred to.
