Title: Control apparatus for a signal generating system
IPC: H04N5/235
Filed: 1964-06-18
Abstract: 1,022,260. Television; cathode-ray tube circuits. HAZELTINE CORPORATION. June 18, 1964 [July 5, 1963], No. 25278/64. Headings H4F and H4T. In an image orthicon the signalto-noise ratio for small signal modulation is poorer than for large signal modulation since the shot noise present for scenes of high or low peak luminous intensity is the same regardless of the size of the signal modulation, and the present invention relates to automatically regulating this ratio. As shown, Fig. 1, the electrons from beam 18 of image orthicon 10 which are not deposited on target 16 are captured by electron multiplier 20 and produce an output signal across resistance 21. Fig. 2 (not shown), depicts, in inverted form, the voltage developed across resisttance 21 as a result of successive scans of the same line in the raster developed on target 16, the saturated black level being obtained during the blanking interval by applying negative voltage pulses A, Fig. 3a (not shown), from pulse generator 25, through capacitance 26 to the target 16. Ep 1 -Ep 8 , Fig. 2 (not shown), designate the peak video voltages for eight successive frames and the shot noise present with the smaller video signal, Ep 4 , is the same as that present with the larger video signal, Ep 1 , since the magnitude of the scanning beam 18 has remained unchanged although it is larger than necessary to discharge any area of the target 16. A reference modulation level (saturated white level) is produced by applying voltage pulses B, Fig. 3b (not shown), through capacitance 27 to the control grid 23 to cut-off the scanning beam 18 and produce pulses P. The output signal of orthicon 10 is applied through an A.C. coupled video amplifier 22 to control apparatus 11 which measures the difference between the peak modulation of a signal modulated electron beam, voltage Ep, and the peak magnitude of pulse P, voltage E s . Detector 30 measures voltage E s  and detector 31, which has voltage pulses C or D, Figs. 3c and 3d (not shown), applied to it to disable it during the occurrence of pulses P or to cancel out pulses P respectively, measures voltage E p . The detector outputs are supplied to an automatic-gain-control distribution network 33 which derives a control signal representative of the difference between voltages Ep and Eg which is fed through biasing resistances 38, 39 and 40 to grid 23 to regulate the magnitude of the scanning electrode beam 18. The time constants of detectors 30 and 31 and network 33 provide charge and discharge times long in comparison to the line scan and frame periods so that regulation of the scanning beam takes place over several frame periods. In a further embodiment, Fig. 4, (not shown), an automatic control signal is derived from the ratio of the output signals developed by detectors 30 and 31 to regulate the magnitude of beam 18 and thus the signal-to-noise ratio.

Title: Improvements in spark gap device
IPC: H01T1/04
Filed: 1954-08-31
Abstract: 775,583. Protective arrangements. GENERAL ELECTRIC CO. Aug. 31, 1954 [Sept. 1, 1953], No. 25286/54. Class 38 (4). A surge protector comprises a preionizing electrode which is coupled capacitively to the main electrodes, there being no direct connection. The arrangement is stated to reduce radio noise or interference. The protector shown comprises two blocks 10 and 11 of insulating material nested together to define a shallow arc shoot 12 within which are disposed two main electrodes 13 and 14, defining a sparkgap 15, and a preionizing electrode 25. Electrode 13 is connected to block 10 by a pin or the like which extends through the block and is connected to a contact-plate 16. Electrode 14 is similarly connected to block 11 and a contactplate 17. One end 20 of a coil 19 surrounding the device is connected to a power transmission line 18 and the other end 21 is connected to contact-plate 16. The coil 19 is shunted by a protective gap 22 and contact-plate 17 is connected to ground through a non-linear resistor 23. A lightning surge on the line 18 breaks down gaps 22 and 15 and passes to ground. The arc across gap 22 gradually ceases but the current from the line 18 tends to maintain the arc across gap 15, and in passing through the coil 19 extends the are towards the remote side 24 of the arc shoot 12 so that the are is cooled by contact with blocks 10 and 11 and is interrupted when the current passes through zero. The preionizing electrode 25 has a rounded end which makes a point contact with the lower surface of block 10, and is attached to a Z-shaped spring element 26 seated in a slot 27 in the block 11. The electrode 25 is positioned on a perpendicular bisector of the gap 15 at such a distance from the gap that a discharge will not occur from the electrode to electrodes 13 and 14, but a corona discharge from the rounded end of the electrode preionizes the gap.

Title: Means for controlling the current density within an electro-plating bath
Inventor: PARFITT RONALD HENRY
IPC: C25D21/12
Filed: 1958-08-07
Abstract: 875,595. Automatic current-control systems. ETHER LANGHAM THOMPSON Ltd. July 24, 1959 [Aug. 7, 1958]. No. 25326/58. Drawings to Specification. Class 38 (4). The current density in an electroplating bath is maintained constant by controlling a variableratio transformer, supplying the bath through a rectifier, by a controller responsive to the voltage between an immersed metallic detector plate having its edges masked from electrodeposition and a cathode of the bath. The controller comprises a galvanometer having a pointer carrying a pair of vanes arranged to allow a light beam to render conductive one of a pair of photo-transistors when the detector-plate voltage varies. The current through the conductive photo-transistor actuates a relay controlling the direction of rotation of a reversible motor driving a slider of the variable-ratio transformer so as to restore the detector-plate voltage to a predetermined value and maintain the current density constant. In a modification, a single vane varies the conduction of a photo-transistor to control the plating current through an electronic or magnetic amplifier. The detector plate is mounted in a plastic frame covering one face and the edges of the plate. Specification 817,053 is referred to.

J., 94, Hope Street, Glasgow.-(Maatschappij van Berkel's Patent Naamlooze Vennootschap ; 33, Boezemsingel, Rotterdam, Holland) Sept. 17, 1935, No. 25735. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 18, 1936.] [Class 27] Articles stored in piles.-In an articledelivery apparatus, the articles are piled in magazines 2<1> . . . , 3<1> . . . , 4<1>. . . of three storeys of magazines 2, 3, 4, Fig. 1, the bottom article of a selected pile being delivered by a drawer, such as 5<1>, Fig. 3, after insertion of a coin and pulling out the selected drawer. As shown in Fig. 1, the top storey 2 is divided into two parts 40, 41 and the articles in part 40 and storey 3 are all of one value so that an article from any magazine in these two groups may be obtained by inserting a coin in a slot 29<1>. Any magazine of the groups 41, and storey 4 may be selected after inserting a coin in slot 29<2>. Various other different combinations of groups of magazines are described and illustrated in Figs. 9 . . . 15 (not shown). When a drawer such as 5<1> is pulled out, a projection 9 thereon engages a ramp 12 on an arm 11 integral with a bar 13<1> and depresses this bar. Bars 13<1>, 13<2> . . . , Fig. 6, correspond to the drawers 5<1> . . . of the group 40 and bars 15<1>, 15<2> ... to the drawers 61 ... of the group of magazines in storey 3. When the drawer corresponding to the bar 15<1>, for instance, is pulled out, a wedge 16<1> on the bar enters between two bars 17<1>, 17<2> of a row of blocking bars, the other bars of the row being moved and preventing any other of the drawers associated with the other bars 15<2> ... from being pulled out. The bar 15<1> acting through a bell-crank lever 20<1> moves a locking rod 18, common to all the drawers 6<1>..., in the direction of the arrow f<2>. The rod 18 enters between two blocking members 23<1>, 23<2> of a vertical series and moves these to lock the common rod 24 of the other series of drawers, 51 ... , thereby preventing any of this series of drawers from being pulled out. The rod 18 acting through a bell-crank lever raises a main payment control rod 25, associated with the coin-releasing mechanism in such a way that the rod 25 cannot be raised nor any drawer of the two associated groups 5<1> ... , 61 ... pulled out, until a coin has been inserted. Coin action, mechanical-connection.-The rod 25 is connected by a link 27 to a lever 28 which is rocked by raising the rod. In the absence of a coin 33, a nose 31 on the lever 28 would engage a notch 32 in an associated lever 30 and prevent the rod 25 from being raised. A coin 33, however, transmits the thrust of the lever 28 to the lever 30 which is rocked so that the nose 31 slides along its upper surface 34.
