Patent GB-1150713-A (GB)
Title: Improvements in or relating to Brightness Control Circuit Arrangements
IPC: H04N9/20
Filed: 1966-05-12
Abstract: 1,150,713. Colour television. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 12 May, 1966 [22 May, 1965], No. 21235/66. Heading H4F. The brightness of a television image is controlled by varying the bias applied from a potentiometer network R1, R2, R3 to the cathode of the final video amplifier 7 (or to the emitter electrode when a transistor is employed), the potentiometer network being so arranged that it presents a substantially constant negative feedback resistance whereby variation of brightness is not accompanied by a variation of image contrast. To this end R1 is made approximately equal to R3 and R2 is made small compared with R or R3. The resistance to earth from the slider of R2 is then equal with the slider at each end of its adjustment and only increases slightly at intermediate positions. The contrast is controlled by potentiometer 6 in the output of the preceding amplifier 2. If the circuit is rearranged so the signal from amplifiers 2 has a negative D.C. component, a negative bias is provided for amplifier 7 by returning resistor R1 to a negative supply. Some variation of negative feed-back may be introduced by making R 1 >R 2  + R 3  so as to compensate for gradation distortion due to the characteristic curve of amplifier 7. Fig. 3 (not shown) illustrates a modified arrangement for use where the bias requirements are such that (R1) cannot be made approximately equal to (R3). The circuit includes a further resistor (R4) connected in shunt with R2 and the smaller of resistors (R1) and (R3). Thus the solid line connection shows the case where (R1)<(R3). The parallel value of (R4) and (R3) is made approximately equal to (R1). (R2) is made small compared with the smaller of (R1) and (R3). Fig. 4 (not shown) illustrates another arrangement in which the potentiometer (R5), (R6) and (R7) include a series variable resistor. (R6) is made large compared with (R5) and small compared with (R7).

The package moving means comprises an upper package trough advancing a plurality of commonly orientated packages in single file to a pocket at one end of the trough, a rotatable member 60 provided with a plurality of package receiving pockets being positioned adjacent the end of the trough to receive and intermittently advance the packages to the replacement station, a lower package trough also being provided to receive packages from the member 60. A pneumatically controlled piston engages the rotatable member 60 to drive it intermittently. The core replacement means comprises a mandrel 95, moveable between two extreme positions, and having a reduced diameter portion and a shoulder portion 98 which engages a trailing end of a longitudinally rigid replacement core R penetrated by the mandrel so as to push the same into the package P as the leading end of the core R pushes the winding core W from the package. The mandrel 95 is operated by a pneumatically controlled piston 97. The package may be lifted and centred at the replacement station and the package on the replacement core may be compressed longitudinally. If the replacement core is a longitudinally compressible spring core, the mandrel may be modified to dnclude dogs which engaged the leading turn of the spring core so that the spring core is pulled into the package as the winding core is pushed therefrom. The actuating means for the replacing means includes means responsive to the movement of a package into proper alignment with the core replacement means, e.g. a trip valve operated by a cam on the rotatable member 60. The piston driving the rotatable member 60 is preferably initially actuated by a manually operable valve. Means may be provided for sensing the size of the package and for diverting packages of other than a predetermined size. A pneumatic control system is described.

Filed: 1929-07-12
Abstract: 336,608. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). July 12, 1929. Glycerine, purifying.- Pure glycerine, is obtained by treating crude glycerine at its B.P. at the reduced pressure employed with finely divided liquids, e.g. mists, inert to glycerine and having a B.P. not exceeding that of water, in admixture with gaseous or vaporous carriers, the operation being continuous. Dilute crude glycerines, e.g. spent soap lyes, and Twitchell process sweet waters, are first concentrated e.g. by spraying on to rotating baffle plates in suitable chambers, or by passing in shallow layers through apparatus provided with air valves, foam receivers, deflecting plates, or other means to prevent excessive foaming; such means may be arranged in apparatus described in Specifications 213,267, 235,792, or 277,085, from which the means for introducing steam have been removed. The conditions are so chosen that . the concentrated glycerine, flows from the last chamber at about 50-60‹ C. into a preheated chamber of the distillation apparatus. In examples : (1) spent soaplye crude glycerine at 160-180‹ C. and 30 m.m. absolute pressure is treated with wet steam having a temperature of 60‹ C. (2) crude saponification glycerine is treated at 180‹ C. and 20 m.m. with a mist of carbon tetrachloride or benzine obtained by sucking air or carbon dioxide at 5‹ C. through the chloride or benzine. The glycerine receivers are maintained at 110‹ C. so that water and benzine vapours pass on.

Title: Improvements in and relating to apparatus for electrostatically spray coating
IPC: B05B5/04
Filed: 1960-06-20
Abstract: 960,102. Electrostatic paint spraying. RANSBURG ELECTRO-COATING CORPORATION. June 20, 1960 [June 18, 1959], No. 21535/60. Headings B2B and B2F. An electrostatic device for coating an article with liquid material comprises an atomizing device with an exposed charging electrode at its forward end connected to an electric circuit which impresses on it a high voltage, but which is so responsive to changes in the length of the air gap between the electrode and the nearest earthed object as to appreciably reduce the potential difference therebetween as the air gap decreases. Liquid is fed to the device for atomization therefrom and charging by the electrode, which is surrounded by a shield of insulating material projecting forwardly thereof greater than the sparking distance from the electrode to the nearest earthed object, but substantially less than would be necessary if the electrical circuit were substantially unresponsive to changes of air gap. As shown, a hand-held gun comprises an insulating body portion 75 and an earthed metal grip 76 with a trigger 77 controlling the flow of liquid coating material. An annular atomizing member 78 is mounted for rotation by a motor 84; it is preferably made of insulating material having a coating of very slight conductivity, and is charged to a high voltage, e.g. 80-90 kV, by a source 81 through resistors 79 and 80, of about 500 megohms each, and a brush 87. Within the member 78 is an inner electrode 82 of insulating material having a slightly conductive coating; this is maintained at an intermediate voltage by leakage current from the member 78 which develops a potential difference across a resistor 83, e.g. of about 10,000 megohms, one end of this resistor being connected to the electrode 82, and the other earthed through the motor 84. A shield 85 of good insulating material, e.g. polyethylene, surrounds the member 78, and projects forwardly, at 85a, beyond the edge 78a, as well as rearwardly at 85b. Coating material is fed to the member 78 through a tube 86, and is atomized at the edge 78a. Specification 865,765 is referred to.

Title: Chad disposal apparatus for a perforator
IPC: B26F1/02
Filed: 1963-05-30
Abstract: 963,003. Removing waste products in industrial processes. TELETYPE CORPORATION. May 30, 1963 [June 22, 1962], No. 21614/63. Heading F4X. In apparatus for the disposal of chad from a perforating mechanism a stream of fluid, e.g. air, is generated to pass through a chadreceiving shot 16 transverse to the direction of fall of the chad and to carry the chad through a duct 17 to a collector 19. The air-stream is generated by rotation in a housing 18 of vanes 35 secured to the drive-shaft 38 of a motor 36. This motor also operates the perforator. Air enters through a mesh-covered opening in a cover 50 and leaves through a mesh-covered outlet 44. The size of the mesh apertures of the outlet 44 can be adjusted to control the air flow whilst preventing the passage of chad therethrough. The relatively small cross-section of the duct 17 produces a high air velocity within it. In operation, the paper tape from a roll 12 is perforated by pins 32 of a punch block 30 entering a die block 31. The chad is drawn from the receiving shoot 16 through the duct 17 by the air-stream and enters the impeller housing 18, enclosing the vanes 35, through a conical connector 40. Beyond the adjustable mesh outlet 44 the chad falls from extension 43 gently into the container 19. The cover 50 is held in position by a spring 52. Should the shoot 16 become blocked with chad the cover hinges downwardly against the spring pressure to release the chad and so prevent damage to the perforator.
