Abstract: 506,143. Cathode-ray tubes. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Oct. 10, 1938, No. 29356. Convention date, Oct. 12, 1937. [Class 39 (i)] In a television transmission tube the discrete photo-electric particles of the mosaic electrode are carried by a transparent insulator which is backed by a transparent continuous metal layer; this layer is made of platinum, rhodium or other metal of the platinum group ; the electrode may consist of a metal frame 5, Fig. 2, in which the mica insulator 6 is fixed. The platinum backing 7 may be applied in a vessel other than the cathode-ray tube by vaporization. In a modification the electrode is formed on the end wall of the envelope by first depositing, by vaporization or cathode disintegration, a layer 12, Fig. 3, of platinum to this is applied a layer 13 of insulation, which may be an alkaline earth borate or a suspension of glass of low melting temperature-glass enamel. This may be sintered. The silver, wall coating 17 for collecting secondaries is spaced from the platinum layer 12, a lead 16 from the latter passing through the wall. The signals may be taken from the resistance 20 connected to the collector layer 17. The photo-electric particles may be separated from the insulating layer by an aluminium braking layer as described in Specification 496,018. It is stated that some of the emitted photo electrons may pass through the insulating layer 13 to the electrode 12 and therefore not interfere with the secondaries emitted due to scanning, and from which the signals are obtained. The mosaic may be inclined within the tube and images thrown thereon from both sides.

Abstract: 638,704. Automatic alignment control systems. PHILCO CORPORATION. Oct. 2, 1946, No. 29433. Convention date, Oct. 3, 1945. [Class 38 (iv)] [Also in Group XL (a)] A picture transmission receiver comprises an electrically conducting frame inside which the picture is reproduced and electronic means restoring the picture to a position within the frame if any tendency to misalignment or change of picture size arises. In Fig. 3, the impingement of the beam of a television tube on border electrodes 4, 2 biasses valves 15, 25 respectively controlling the D.C. current through coil 14 centring the image and the amplitude of the sweep voltage through the same coil. The bias on valve 25 controls the rate of discharge of condenser 29 between synchronizing pulses from a valve 31 and this rate of discharge is amplified at 24 and passed through a condenser 13 to the coil. A similar electrode pair may control the other dimension of the picture. Alternatively the amplitude control bias may be directly applied to the amplifier 24. In a modification, Fig. 4 (not shown), a deflection amplitude is controlled by a single electrode, feeding back to a gain controlled saw-tooth amplifier, and at the same time the electrode current and amplifier input are sharply increased by voltage feed-back 'across a resistor connected to the electrode, to a valve 35 with cathode load resistor forming the bias resistor of the cathode-ray tube. The beam current thereby saturates so that the control functions independently of the modulation at the extreme edges of the picture.

Abstract: 1,072,150. Automatic control of moving webs. BADEBEULER MASCHINENFABRIK VEB. July 14, 1965, No. 29876/65. Heading G3R. Tensions in a web of material passing from a delivery roll to a winding roll via a take-up roll are maintained constant by automatic control of an electromagnetic clutch and brake. In the arrangement described, a web passes from a delivery roll, which is controlled by an induction brake, to a take-up roll which is driven through an induction coupling the energization of which is preset. A signal dependent on the speed of the take-up roll, derived from a tachometer generator is compared with a signal dependent on the energization of the brake by a bridge circuit, and any difference is effective through an amplifier to control the energization of the brake to maintain a constant tension in the material. The material passes from the take-up roll to a winding driven through an induction coupling the energization of which is controlled by a signal dependent on the speed of the roll acting through an amplifier having feedback automatically varied in dependence on roll diameter to maintain tension constant.

Abstract: 365,048. Ventilators. GALBRAITH, A. and ANEMOSTAT (SCOTLAND), Ltd., 247, West George Street, Glasgow. Oct. 11, 1930, No. 30491. [Class 137.] In a ventilator of the type comprising a number of partitions arranged one within another to provide a plurality of passages which increase in area from one end to the other, one or more of the partitions is or are adjustable at will relatively to the inlet to the ventilator. As shown in Fig. 1, the ventilator comprises five coaxial conical partitions of which the outer one 25 is connected to a tubular inlet 26 and supports by means of stays 32 the adjacent partition 24. The three inner partitions 21, 22, 23 are connected together by stays 30 and may be adjusted axially as a unit bv means of a thumb-piece 31 on the lower end of a screwed spindle 29 working in a screwed bush 28 attached to the inlet tube 26. A sleeve 36 may be provided on the inlet tube to form a hit-and-miss valve through the apertures of which air from the enclosure may be entrained. The inner ends of the partitions are bent over to form a beaded edge 35 of substantially stream line form to reduce the noise of the incoming air. In a modified form, Fig. 5, the adjustable unit comprises four connected partitions, the inner being fixed to a tubular member 40 which forms 'a seat for a ball 41 at the end of the screwed rod 29. By means of a thumb-piece 31 and a nut 42 the adjustable partitions may be turned and clamped in an angular position. The upper end of the spindle 29 carries a plate 43 adapted to close the inlet when the partitions are fully extended. In another modification the four adjustable partitions are carried by a system of pivoted links acting on the lazytongs principle. In a further modification, Fig. 8, the adjustable partitions are detachably mounted by means of slotted bars 85 hinged at their upper ends to brackets 84 on the partition 24 and at their lower ends retained by a ring 86. This unit is carried by three vertical stays 56, two of which are 180‹ apart and the third midway between. Each stay carries at its upper end a stud 57 which projects through a sloping slot 61 in the wall of the inlet. The unit can thus be raised or lowered by a rotating movement and is held in adjusted position by springs 59. That slot which is 90‹ from each of the other two is also provided with vertical branch slots 62. By allowing the corresponding stud to move down one of the branch slots, the partitions may be angularly adjusted. One of the studs 57 is also arranged to actuate a valve comprising two semicircular flaps 76, 77 pivoted about an axis 78. As the stud moves up the slot 61 it engages and moves a rod 79 connected directly to the flap 76 and through a system of levers to the flap 77. The inlet tube 26 is shown lined with felt 88. Specification 330,270, [Class 137, Ventilation], is referred to.
