Title: Improvements in and relating to exposure meters and apparatus for measuring brightness
IPC: G01J1/42
Filed: 1950-07-04
Abstract: 693,443. Exposure meter. GENERAL ELECTRIC CO., Ltd., and THOMAS, E. R. Oct. 25, 1951 [July 4, 1950], No. 16698/50. Class 98 (i). [Also in Group XL (b)] A brightness measuring system of the type in which an area is scanned photo-electrically, the output of the cell feeding one pair of plates of a cathode-ray tube while the other pair are fed by a time base generator synchronized with the scanning is modified for use as an exposure meter by the provision of means for adjusting the quantity of light reaching the cell. Such a system is described in Specification 599,750, [Group XL]. As shown, light from the scene under examination passes through an objective lens 2, a scanning disc 10 consisting of a series of radially-spaced apertures, a condenser lens 14 and a gate 16, through which may be passed a length 17 of 35 mm. film of varying density, and on to a photo-multiplier tube 13. This tube feeds the " Y " plates of a cathode-ray tube 7 through an amplifier 24, the response of which may be logarithmic. The " X " plates are fed with the output of a time-base generator synchronized with the disc by means of magnetic studs in the disc as described in Specification 599,750. A further lens 8 and a receiving screen 4 are provided to align the apparatus on the subject. When the apparatus is in use as a photo-electric exposure meter a calibrated knob 19 is used to move the clear part of film 17 into the light path. An object of known brightness is then scanned and the sensitivity of amplifier 24 adjusted until the deflection of the spot on the screen coincides with prepared marks on a graticule. An A.C. fed standard lamp 15 is then inserted, the resulting trace being used for calibration purposes. Dial 19 then sets the film to correspond to camera aperture and the deflection on the screen may be used in conjunction with a calibrated graticule to indicate if the brightness is such that linearity of film response fails. This enables scene illumination to be adjusted. Alternatively if the scene lighting is predetermined and the dial used to bring the deflection within limits on the graticule then the setting of the dial may indicate exposure time. To avoid the necessity of designing an amplifier to handle a wide signal range a filter may be placed between the objects and the photo-cell and two graticules provided to indicate the upper and lower limits of brightness for linearity of film response.

Electrostatic coating apparatus comprises means for creating a floating cloud of finely divided coating substance at a coating station, means for presenting articles to be coated at said station, charging electrode means connected to a high electric potential relative to said articles and positioned to be closely approached by substantially all the particles in said cloud to charge the particles to a corresponding potential whereby particles from the cloud will be guided over lines of electric force towards said articles, and auxiliary ionizing electrode means connected to a potential substantially the same as the potential of the articles and positioned in spaced relation with said charging electrode and with the articles for controlling the spatial extent of the cloud by discharging the electrical charge of the particles entering into the ionizing zone of the auxiliary electrode means. The apparatus shown includes an insulated tank 1 having a perforated false bottom 2 which supports coating material 3. The space under false bottom 2 is connected by pipe 4 to a source of fluidizing gas under pressure and a vibrator unit 5 may be provided to assist in the fluidization of coating material 3. Means for electrically charging the particles in the fluidized cloud of coating material consists of an array of point electrodes or ionizers 6 connected to one terminal of high voltage source 7. In operation with source 7 in action and compressed air delivered through pipe 4 the coating material 3 is converted into a turbulent floating cloud and the electrodes 6 impart to substantially all the particles in the cloud a high electric potential. When articles to be coated (not shown) and at earth potential are support above the tank 1 said coating particles flow along the lines of force established and are deposited on the surface of the article to be coated. To control the spatial extent of the fluidized cloud of coating material control. electrodes 8 are fitted and in operation these electrodes act to discharge any cloud particles approaching them and thus prevent any undesirable spilling from the tank. The electrodes 8 may be in the form of point electrodes as shown or they can be in the form of wires running round the periphery of the tank. In a further embodiment the fluidized cloud is produced by an electrostatic spray-gun.

Title: Improvements in or relating to supply circuits for thermionic valves
IPC: H04B3/46
Filed: 1937-06-18
Abstract: 497,364. Valve circuits. STANDARD TELEPHONES & CABLES, Ltd., MEERS, R. A., and FILBY, F. G. June 18, 1937, No. 17018. [Class 40 (v)] Current limiting means inserted in the cathode heating circuit of thermionic valves, to reduce the initial current at first switching in, are automatically cut out of circuit when the discharge current of one of the valves reaches a predetermined value. Thermionic valves V1-V8 in a two-way thermionic valve repeater having indirectly heated cathodes have their cathode heating filaments connected in series in two groups V1 .. V4 and V5 .. V8 the heating circuits having series connected current lirniting resistances R1, R2 which are cut-out when the anode current of one of the valves reaches a predetermined value. Each of the valves has an alarm relay NSA ... NSH in its anode circuit which operates an alarm circuit only when the anode current of any valve drops below a predetermined value after normal operation. Valve V1 also has a relay S operating at a lower current valve than NSA in its anode circuit. At first switching on, the resistances R1 and R2 are in circuit and the heating current is limited. As the anode current rises relay S operates and its contacts S1. short circuit the resistance R1 bringing the anode current of valves V1-V4 to normal. Relays NSANSD operate and contacts NSB1-NSD1, (Fig. 2) open. Contacts NSA1 (Fig. 2), close and operate a relay NSX to close contacts NSX1-3 (Fig. 1), and NSX4 and 5 (Fig. 2). Contact NSX1 short circuits relay winding S to bring the anode circuit conditions of valve V1 to normal. Contacts NSX2 and 3 short circuit resistances R1 and R2 bringing the heating circuits of all the valves to normal. Contacts NSX4 complete a circuit to earth of a slow release relay NSY whose contacts NSY1 close in the circuit of an alarm relay ALM. Meanwhile relays NSE-NSH operate and their contacts NSE1-NSH1 open so that closure of contacts NSX5 do not energize the alarm relay during running up. If the current in any of the valves V2-V8 now drops below normal the corresponding relay NSB-NSH releases and one of the contacts NSB1-NSH1 closes thereby energizing relay ALM whose contacts ALM1 energize an alarm lamp L and a relay ALN energizing an alarm bell. If valve V1 fails its relay NSA releases and contact NSA1 opens to de-energize relay NSX but the circuit of the alarm relay ALM is completed over the back contact of contacts NSX4 and the winding and contacts NSY 1 of the slow release relay NSY. The alarm is cut off by contacts bco operated by plugging the jack BCO (Fig. 1), whereby the heating and plate circuits are also opened. Each pair of coupled valves such as V1, V5 is connected to a common H.T. lead through a lamp L2. Variable resistances R3 and fuses F are provided in the battery circuits. Jacks AMM are provided for inserting a meter in each cathode heating circuit.
