Title: Improvements in methods of and apparatus for television
IPC: H04N3/08
Filed: 1929-07-29
Abstract: 317,475. Peterson, E. L. Aug. 18, 1928, [Convention date]. Vacuum tubes.-A television system utilizes changes in wavelength and intensity of the transmitted signals, to produce changes in position and intensity of a scanning light beam at the receiver. In the transmitter, light from an object passes after scanning to a light-sensitive device consisting of two conductors 28, 29, Fig. 13, the latter bearing a sensitive coating 30, contained in a tube 27. By virtue of its change in resistance or inductance according to the position of the incident light beam, the wavelength of the transmitter is varied. The electrode 28 may be a coiled or stranded wire in which case a lead is taken from both ends, 28<1>, 28". At the receiver, the signals are fed to an inductance 35, Figs. 6, 9, the nodes of whose field will alter in position according to the wavelength, and a vacuum tube 36 is arranged in the field. The tube contains a cathode 37, Fig. 10, having a concave surface coated with light-sensitive material 38, a neon tube 39, a grid 80, a primary anode 44, and one or more secondary anodes 52, 53. A longitudinal opening 40 in the neon tube 39 is closed bv a metal strip 41, while the anode 44 has parallel walls 45, 46 of conducting material, spaced by walls 47, 48, the latter being translucent and preferably of lens formation as at 49, and is filled with neon, made luminous by the electron stream from the cathode 38 and strip 41. The secondary anode 52 has a portion 52<1> parallel to the wall 47 of the primary anode, which may have a reflecting coating, and serves to prevent light from escaping through wall 47. Were it not for the field of coil 35, the whole of the neon in the anode 44 would be luminous, but in operation the electrons travelling to the primary anode are diverted by the field to the secondary anodes except in the plane of a node and thus the primary anode is luminous only in that plane corresponding to the wavelength being received. The light is reflected from a scaning drum 55 rotated at the same speed as the drum at the transmitter, so that one of its surfaces is presented to the anode for each complete picture presented to the scanning disc. In order to vary the intensity of the luminous anode discharge a luminescent tube 58 is energized by induction from the coil 35, and the light from it passes through a lens 59 to a light-sensitive cell 60, which controls the potentials on the elements of the tube 36. The cell 60 comprises a tube 61, Fig. 11, preferably evacuated, having a support 62 of glass &c., oonvexed at 63 and provided with a light-sensitive coating 64, whose surface is at all points normal to the incident radiation. An electron-collecting hood 67 serves as the other electrode.

Abstract: 392,892. Reversing-valves for cokeoven regenerators. ACKEREN, P. VAN, 62, Irmgardstrasse, Essen, Germany. Aug. 18, 1931, No. 23242. Convention date, Aug. 18, 1930. Void [Published under Sect. 91 of the Acts]. [Class 51 (i).] In reversing-apparatus for coke-oven regenerators the valves 10, 11 controlling the inlet of weak gas and the outlet of waste gases are connected to the operating means through lost-motion connections comprising pistons 18, 24 slidable in tubes 12, 21 on the valve stems. The valve casing 1 is supplied with weak gas by a pipe 4 provided with a seating 6 for the valve 10, and communicates with the regenerator by a connection 2 and with the waste gas flue by a connection 3 controlled by the valve 11. The shaft 28 of the reversing mechanism is rocked by a lever 38 and has two sectors 29, 30 connected by chains 32, 37 with the rods 17, 25 of the pistons 18, 24 slidable in the tubes 12, 21 connected to the disc valves by members 13, 20. When the ovens are heated by rich gas the chain 32 is disconnected from the weak gas valve 10 and connected with an air inlet flap 40 pivoted at 41 to a lever 42 pivoted to the casing 1 at 44, and a clamp 46, which normally retains the air flap closed, is released. The amount of lost motion is adjusted by altering the position of end caps 16, 23 screwed on the tubes 12, 21. A clean-out cover 8 is provided.

Title: Line tracing apparatus for controlling a machine tool
IPC: B23Q35/128
Filed: 1962-06-18
Abstract: 985,055. Photo-electric template followers. SIEMENS-SCHUCKERTWERKE A.G. June 18, 1962 [June 20,1961; Sept. 2, 1961], No. 23433/62. Heading G3N. In a line tracing apparatus for a machine tool an oscillating mirror 5, driven magnetically, reflects a reading light beam from a drawing on to a photo-electric cell Ph which supplies a pulse, each time the reading beam intersects a curve on the drawing, through a differentiating circuit D to a monostable trigger stage MK which supplies a pulse of constant length each time the photo-cell pulse exceeds a limiting value. The output of the trigger stage MK is fed to the inputs of a pair of AND gates U 1 ,U 2 . The gates are opened by a pulse generator VJ, controlled by the rectified mirror driving alternative voltage, having two outputs phased 180 degrees apart. The length of the pulses from the AND gates is determined by the phase relationship between the gating pulses and input pulses and by means of a phase shifting arrangement, not shown, short equal pulses are derived from the AND gates when the reading beam is on the drawn curve. The AND gate pulses are fed through power amplifiers P 1 , P 2  to opposed excitation windings W1, W2 of a Ward-Leonard generator G energizing an adjusting motor M for the reading head and a directly coupled gas blow torch, not shown. The motor M is kept in light vibration when the reading beam is on the curve by the short equal pulses from the AND gates and for a deviation of the tool from the curve pulses, varying in duration with the deviation, are derived from the appropriate AND gate so as to tend to reduce the deviation. The motor M may control a steering motor for the reading head assembly or move the armature of a co-ordinate resolver controlling X and Y co-ordinate adjusting motors.

Abstract: 901,475. Control of motors. BULPITT & SONS Ltd. Oct. 31, 1958 [July 31, 1957], No. 24231/57. Class 38 (3). [Also in Groups XXIII and XXXV] A dish-washing machine comprises an electrically-heated storage tank for receiving a quantity of water for the washing or rinsing stage in the operating cycle of the machine, and means for limiting the temperature to which the water in the storage tank is heated and thermally actuated means for initiating a device controlling the succeeding stages in the operating cycle when the water in the storage tank reaches a predetermined temperature. As shown, water is heated in tank 12 and when it reaches a desired temperature as a result of heating by immersion heater 17, a thermallycontrolled change-over switch 42 is actuated to turn off the heater and at the same time to start timer clock 47 and also to allow fresh water to flow into tank 12 at a predetermined rate governed by a variable area orifice device for a predetermined time governed by timer 47. The fresh water displaces the heated water through hose 15 into the washing chamber where it is circulated by pump 28 through sprays 30. Crockery rack 32 is supported at the front by rollers resting in brackets 35, near the hinges of door 31, which serve to pull the tray forward slightly when the door is opened. Used water is drained from the machine by the energization of a solenoid which pulls down an arm against the supporting tension of springs 36 lowering flexible drain hose 25 so that water flows out of the machine. Fig. 4 shows the supply terminal 40 connected to heating resistor 41 of immersion heater 17 and via thermally operated switch 42 and contact 50 of relay 45 back to terminal L. While loading the crockery racks, push-button switch 48 may be depressed to complete a circuit through door-operated microswitch 44 which is in the position shown when the door is open, through coil 52 of relay 45, through contact 56 of camshaft timing device 46 back to terminal N. The energization of coil 52 actuates contacts 50, 51 and 58 of relay 45 bringing heater resistor 41 into the circuit, completing the holding circuit, through coil 52 via contact 51, and energizing warning light 49. The closure of the door actuates microswitches 43 and 44 but timer motor 47 does not start until the temperature of the water causes the actuation of change-over switch 42. The process is then controlled by timing device 46, motor 47 being kept in motion by current supplied over contacts 57 when the change-over switch returns to its original position upon the introduction of a fresh charge of cold water in the tank 12. Specification 901,476 is referred to.
