Title: Improvements relating to circuits for deriving phase and amplitude modulated sawtooth signals
Inventor: GARGINI ERIC JOHN
IPC: H04N9/22
Filed: 1957-07-24
Abstract: 893,871. Valve amplifying circuits; sawtooth generators. ELECTRIC & MUSICAL INDUSTRIES Ltd. July 18, 1958 [July 24, 1957], No. 23389/57. Class 40(6). [Also in Group XL(b)] In a colour television receiver utilizing a sinusoidal phase and amplitude modulated chrominance sub-carrier wave the velocity with which the beam of the picture reproducing tube scans, transversely, the colour phosphor strips which constitute the screen is controlled by a sawtooth wave modulated in phase and amplitude correspondingly to the modulation of the sub-carrier wave. In one embodiment the sub-carrier wave is supplied to the control grid of a valve 1 (Fig. 1) the anode circuit of which includes an inductor 2 and a capacitor 4. During a certain part of the sub-carrier cycle and at an instant dependent on the phase of the latter the capacitor 4 discharges through inductor 2 resulting in free oscillations of amplitude determined by that of the sub-carrier and the charging of capacitor 12 (which is of small capacity compared with capacitor 4) to a relatively high potential which is sufficient to cut-off diode 3. This results in the production of a short duration pulse which causes diode 5 to conduct and charges the capacitor formed by the line deflection plates 7 of the picture tube 8 to a potential determined by the amplitude of the sub-carrier wave at the instant considered. This potential change produces the "shortflank" of a sawtooth wave the "long-flank" of which is produced by the relatively slow discharge of the charge on plates 7 through resistor 9. In a second embodiment (Fig. 2) the capacitor formed by plates 7 of Fig.  is constituted by the grid-cathode capacity of a valve 20 which therefore acts to amplify a sawtooth wave produced as described in connection with Fig. 1. It is stated that adequate velocity modulation control can be produced by maintaining harmonics of the sawtooth wave only up to the 3rd (the fly-back time then being 1/6 of a complete period) and to effect this the anode load of valve 20 comprises circuits 21, 22 and 23 resonant at frequencies of 5 mc/s. (the average frequency of the sawtooth wave), 10 mc/s. and 15 mc/s. respectively. Instead of supplying the amplified sawtooth wave to deflection plates 7 which, and as in the case of the embodiment of Fig. 1, may be positioned either inside or outside the tube and may also be supplied with the normal line scanning waveform, electromagnetic deflection by means of the coils 21, 22, 23 may be employed. Specifications 776,003 and 871,367 are referred to.

Title: Improvements in or relating to logical circuits using transformers
IPC: G06F7/38
Filed: 1956-07-31
Abstract: 837,005. Logical circuits using magnetic cores. SPERRY RAND CORPORATION. July 31, 1956 [Aug. 15, 1955], No. 23649/56. Class 40(9). The short circuit impedance of a transformer is used to construct AND and OR gates. If winding 12 on a core 10 with a linear B-H characteristics, Fig. 1, is short circuited, the impedance of winding 11 is reduced to permit the application to a load 14 of the positive halfcycles of an alternating source PP. If winding 12 is open circuit, winding 11 has a high impedance and prevents the application of pulses to load 14. Closure of any one switch 15, 16, 17 opens the gate. In Fig. 3, three separate transformers are used with linear B-H cores and series connected windings 33, 34, 35 supplied with positive pulses from a source PP. In this arrangement all the windings 36, 37, 38 must be short circuit before load 14 is energized. If cores with a high degree of remanence are used reset windings are provided and are energized by the negative half-cycles of the source PP. The switches 15, 16, 17, of Fig. 1, or 36a, 37a, 38a, of Fig. 3, are signal responsive devices such as transistors or gas discharge tubes. Alternatively, a transformer winding 12 may be short circuited by the magnetic amplifier shown in Fig. 8. Here, if core 82 is saturated, current is delivered to a resistor 88 from an A.C. source 85 sufficient to unblock a rectifier 89 and short circuit the winding 12. If core 82 is withdrawn from saturation by an input signal on any input lead 80, insufficient current is delivered to resistor 88 to unblock rectifier 89 and winding 12 has high impedance.

Title: Process for the electrolytic production of hyper-pure zinc
IPC: C25C1/16
Filed: 1961-06-30
Abstract: 914,515. Electrolytic production of hyper-pure zinc. MONTEVECCHIO SOC. ITALIANA DEL PIOMBO E. DELLO ZINCO. June 30, 1961 [July 5, 1960], No. 23731/61. Class 41. Electro-deposition of hyper-pure zinc containing less than 5 p.p.m. of lead and having a purity of not less than 99.999%, by electrolysis of zinc sulphate solution, purified of impurities other than lead, using a lead or lead alloy anode with a subsidiary anode, comprising an electrolyte-impermeable diaphragm, coated with deposited manganese dioxide to render it electrically conductive and completely impermeable, surrounding the anode and isolating it from the cathode. The diaphragm separates the anolyte from the catholyte and prevents transference of electrolyte across the diaphragm ; it also prevents contamination of cathodic zinc deposits by solid anode slime products. The lead anode acts only as the current conductor ; the anodic phenomena, e.g. oxygen evolution, and current discharge being performed by the subsidiary diaphragm anode. The deposition of manganese dioxide renders the diaphragm almost completely impermeable whence the acidity of the anolyte contained in said diaphragm rises to much higher values than normal, reaching concentrations of free sulphuric acid of 250-280 gms./litre. The high acidity of the anolyte results in (i) high electric conductivity, (ii) substantially reducing the formation of PbO 2  at the anode, (iii) lowering to low limits the solubility of Pb <SP>+ </SP><SP>+</SP> ions in the electrolyte, (iv) practically zero solubility for PbSO 4 , so that lead dissolved by anodic attack precipitates completely within the diaphragm without contamination of the catholyte and concomitant deposition with the zinc as in processes hitherto. The electrolytic cell, Fig. 1, is coated with anti-acid polyvinyl chloride and comprises lead or lead-alloy (1% Ag) anodes 1 contained in diaphragms 2 of compact weft in acid-resistant vinyl resin yarn interposed with cathodes 3. Neutral zinc sulphate solution is admitted at A and spent electrolyte of low acidity (50-60 gms. of H 2 SO 4 /litre) is discharged at B. The cell operates with a current density of from 200- 250 amps./m.<SP>2</SP> at 30-35 C. The adherent, compact, electrically-conductive MnO 2  on the diaphragm is formed by including 1 to 5 gms./litre of Mn + + in the zinc sulphate electrolyte which should also be leadfree with Cd < 0.002 gms./litre.

Title: Improvements in or relating to apparatus for heating toothed or serrated portions ofarticles by high frequency induction heating
Inventor: JONES DAVID GRIFFITHS
IPC: H05B6/40
Filed: 1954-08-17
Abstract: 813,113. Induction heating. DELAPENA & SON Ltd. Aug. 4, 1955 [Aug. 17, 1954], No. 23857/54. Class 39(3) An inductor for use in heating toothed or serrated portions of articles, e.g. gear wheels and chain sprocket wheels, enables overheating of the edges of the teeth or serrations, as the inductor passes through the tooth space, to be avoided. As shown, an inductor for use with a high frequency supply, e.g. of radio frequency or in the region of 10,000 c.p.s., comprises two copper outer conductors 16, 17 between which and insulated therefrom by sheets 19 of mica is sandwiched a further copper conductor 18. A copper nose-piece 30 is brazed to the three conductors, and a conductor band 24 is secured by bolts 25 to the outer conductors only, bushes 27 serving to insulate the conductor 18 from the bolts. Flux-concentrating cores 41, 42 are formed from thin laminae insulated from each other and are positioned by wedges 49, channels 50 being formed in the cores to carry coolant which also flows through spaces 46, 46a formed in the outer conductors 16, 17. In heat treating the teeth 38 of a gearwheel 11, the current supply is connected to the conductors at their ends 16a, 17a and 20a and the inductor is moved into tooth space 12 from a face of the gear wheel, e.g. in the direction shown, the clearance between the nose end 28 and the trough 15 of the space being approximately 0.010 inch and that between the edges of the conductor body and the flanks 14 of the teeth approximately 0.030 inch. As the inductor enters the tooth space only one quarter of the heat is induced in the edges 39 of the teeth as is subsequently induced along the tooth flanks 14 by the central conductor 18 when the latter has completely entered the tooth space, the heating effect diminishing in a similar manner as the inductor starts to leave the other edges 40 of the teeth. The width of the first outer conductor to enter the tooth space may be made greater than that of the trailing outer conductor to impart greater heat to the teeth edges 39 than is imparted to the already heated edges 40 by the narrower trailing outer conductor as the inductor leaves the tooth space. The flux-concentrating cores may be constructed of insulated powdered magnetic material or of a ferrite material. Specifications 714,488, and 775,463 are referred to.
