Title: Improvements relating to means for controlling the power dissipation in electric heaters
Inventor: PANISSET DENIS SYDNEY
IPC: G05D23/24
Filed: 1955-07-01
Abstract: 802,372. Automatic control systems for electric heaters. SIMPLEX ELECTRIC CO., Ltd. Aug. 2, 1956 [July 1, 1955], No. 19032/55. Class 38 (4). [Also in Group XI] In a control having a regulator effecting a cyclic variation in current supply to an electric heater R1 having, in thermal communication with the heater as primary control R4 for the regulator, a resistor of a material with a resistance changing with temperature, e.g. a nickel strip and heating means R3 for a thermal responder 14 (e.g. a bimetallic strip) with contacts Sl in parallel with the primary control R4, a ballast resistor R5 for the control R4 is so disposed relatively to the heater R 1 that the ballast resistor R5 does not contribute significantly to the heat developed in the controlled heater R1, but is placed to heat a part of the heated apparatus separate from the controlled heater R1. Thus a cast-iron hotplate with a central plate 10 carrying in grooves the heater R1 and the nickel strip R4 is closely surrounded by an annular plate 11 carrying a heater R6 directly connected through a manual switch S2 to the supply terminals t1, t2. The annulus 11 fits closely in a rectangular plate in one or more parts 12, 13. The ballast resistor R5 may be attached to the outer plate 12 for keeping a saucepan warm or may be used in a warming compartment of a cooker, e.g. for warming plates. The innermost hotplate 10 may carry further heating resistors subject each to a similar control with a separate ballast resistor; and if four such heaters are used, a ballast resistor may be placed in each corner of the rectangular plate 12. The innermost plate 10 may also carry resistors not subject to these controls. The current variation in the controlled heater may result purely from the change in resistance of the nickel resistor R4 and in this case the control is thermostatic; or the current variation may be compounded of a cyclic variation corresponding to that which the regulator imposes on the current for the heater, e.g. by connecting the parallel combination of nickel resistor and heating means for the responder in series with the regulator, together with a superimposed component of the variation derived purely from resistance changes in the nickel strip, and in this case the control will comprise an energy regulating characteristic with a superimposed thermostatic characteristic. Two nickel strips may be connected with two ballast resistors to form a bridge circuit across opposite points of which is connected the heating resistor R3. Specification 710,560 is referred to.

Title: Improvements in or relating to railway track control and indicating panels
IPC: B61L25/08
Filed: 1937-07-09
Abstract: 498,143. Railway signalling-apparatus; switches. STANDARD TELEPHONES & CABLES, Ltd., GRIFFITHS, J. B., and BROWN, A. July 9, 1937, No. 19114. [Class 105] [Also in Group XXXVII] At positions of route divergence on miniature diagram panels, multi-position manual switches in each of their different settings complete control circuits for setting up a route from such position over a number of track points and clearing the signals. In the arrangement shown in Fig. 2 a single multi-position switch 4 provided at each position of route divergence sets up all the routes starting therefrom. An indicator disc presents the route indication at an aperture 5 in the panel and the signal indication is given by lamps 6, the green lamp being lit when a multi-aspect signal is at any aspect other than stop. The switch shown in Fig. 3 comprises a knife-switch section and a spring-contacts section. The spring contacts 28 are opened by cam fingers 27 carried on a rotatable spindle 17. The knife-switch contacts 11/16 are closed by depressing the head 8 of a sleeve member 9 after movement to the required angular position, such angular movement also being given to the spindle 17 by a pin 19 extending through a longitudinal slot 18 in the sleeve 9. The pin 19 also actuates the indicator disc 7 to present an indication at the aperture 42. A stud 12 on the hub of the knife switch enters a hole 14 to prevent the turning of the switch while depressed. The spring- contacts section may serve for the normally closed contacts of the route-setting apparatus described in Specification 496,495 and the knife-switch section for the contacts closed at " reverse." It will be seen that the spring contacts are opened prior to the closure of the knife switches. Both sets of contacts may however be operated by the axial movement. A spring click arm 21 engages recesses 22 at each angular position.

Title: Improvements relating to high-frequency electrical heating
IPC: H05B6/04
Filed: 1945-07-30
Abstract: 598,926. Valve generating circuits. MITTELMANN, E. July 30, 1945, No. 19514. Convention date, July 21, 1944. [Class 40 (v)] [Also in Group XXXV] In a high-frequency electrical heating system having a generator feeding a reactive heater over a variable-impedance coupler, the coupler and an element in an associated tuned circuit are interconnected to maintain the circuits tuned with change of coupling to ensure matching of the load to the generator. A source of high-frequency oscillations 20 feeds, over transformer 24 an inductive heater 18, condensers 26, 28 tuning the secondary of the transformer, condensers 30, 32 and inductor 34 being adjustable to match the load to the source. Upon the impedance of the heater varying, the change in amplitude of the highfrequency oscillations applied to transformer F3 causes one of the thyrations F6 or F7 to fire and motor F1 to adjust the coup.ing condenser 30 to restore matching. To avoid changes in frequency, the tuning condenser 28 is coupled to the same drive shaft as condenser 30. A variable inductor may be employed for matching, Fig. 9 (not shown), or the coupling between the primary and secondary of transformer 24 varied, (Figs. 11, 12 and 15, not shown). A split secondary arrangement may also be employed, (Fig. 14, not shown). In a further modification, (Fig. 16, not shown), the load is fed through adjustable coupling condensers from tapping points on a tuned inductor, the coupling and tuning condensers being varied simultaneously.

Title: Improvements in or relating to cathode ray image pick-up devices
Inventor: MCGEE JAMES DWYER
IPC: H01J31/36
Filed: 1954-07-03
Abstract: 807,992. Television pick-up tubes. ELECTRIC & MUSICAL INDUSTRIES Ltd. June 16, 1955 [July 3, 1954], No. 19544/54. Class 39(1). A cathode ray pick-up tube circuit arrangement comprises a target 2 of slightly conductive glass having a separate photocathode 10 for projecting a composite stream of photoelectron on to one side of the target 2 with such a high velocity that the secondary emission ratio exceeds unity to form a positive charge image which is read off by a low velocity scanning beam from gun 3, 4, 5, "sticking, " which occurs after some hours of operation is removed and the tube "rejuventated" by operation for a short period by changing the electrode potentials so that the scanning beam has a high velocity and the photoelectrons from the photocathode have such a low velocity that the secondary emission ratio is less than unity lay down a negative charge image on the target. 10 hours of normal operation in the cps regime may be followed by one hour's operation in the high velocity regime to give "rejuvenation." This short period of rejuvenation can be achieved by increasing the scanning beam current (by increasing potential of 4) or by increasing the amount of light falling on the photo-electric cathode 10 (the photocathode being uniformly illuminated during rejuvenation). Sticking is defined as lag or persistence of signal output after cut off of light, the undesired output being often of reversed polarity, and is stated to be due to electrolysis in the glass target, which is usually of soda-lime glass, the sodium ions migrating from one side of the target to the other, proportionally to the photocathode illumination ; rejuvenation causes current flow in the opposite direction. Suitable electrode potentials for cps and high velocity electron beam scanning obtained from potentiometers 7 and 8 are given, switch over from one regime to the other being effected manually or by relays. The scanning gun 3, 4, 5 is surrounded by multiplier 9 from which the output signal is taken during normal low velocity operation, and is followed by persuader 6, shield 7, decelerating electrode 8, while the photocathode 10 is followed by accelerator 11 and electrode 13 connected to mesh 12. The focusing solenoid 16 ensures normal approach of the beam to the target 2, and 14, 15 are horizontal and vertical scanning coils.
