A differential amplifier 31 compares a proportion of this voltage from a potentiometer 29 with a reference voltage V 2 . A capacitor 35 gives the regulator an integral characteristic, so that the output from the amplifier 31 represents a time average of the current error which is used to control a drive circuit 15 for gating SCR's 14 in the phase lines. Further differential amplifiers 39, 54_compare different proportions of the D.C. feedback voltage with reference voltages V 4 , V 5  respectively.

Abstract: 538,381. Thermionic valves and circuits therefor. STANDARD TELEPHONES & CABLES, Ltd., and JACOBSEN, B. B. Jan. 30, 1940, No. 1853. [Classes 39 (i) and 40 (v)] The effective mutual conductance of a valve having an accelerating grid is increased by positive feedback from a secondary emitting electrode, having a resistance in circuit therewith, to a point in the electron stream where the electron velocity is low. The secondary emitting electrode may itself be arranged at a point in the electron stream where the velocity is low. Fig. 1 shows feedback through condenser 15 from the secondary electron emitting grid 5 to an auxiliary grid 2. The accelerating electrode 4 is at a higher potential than the grid 5 and, in addition there may be provided a screening grid which assists in withdrawing secondary electrons and a suppressor grid. The control and auxiliary grids 2, 3 may be interchanged or intermeshed, and the secondary electron emitting grid 5 may itself serve as the auxiliary grid for providing reaction. Fig. 5 shows'an arrangement in which the secondary electron emitting grid 5 serves as the control grid and feedback is applied through the secondary of the input transformer 24 to the auxiliary grid 3. Fig. 7 shows an additional feedback through network 24 to increase the effective input capacity. Condenser 15 and grid 2 may be omitted so that the sole feedback is through the network 24. Negative feedback may be applied by resistance 19 which may be temperature dependant so as to further stabilize the operation. Control of grid bias through resistance 17 may be used for automatic volume control and gives a large range of control.

A method of extruding billets 50 comprises arranging them in tandem, Fig. 1, and plasticizing and extruding the leading billet through an extrusion die. The billets which may be of aluminium, lead, tin, copper, magnesium or their alloys are supported on idler rolls 36a and are driven by feed rollers 36, 36b towards a roller feed bed 12.

[Also in Division G4] An alarm device for a closure member and a member to which the closure member can be fastened in its closed position, comprises an anchor plate 28 for securing to one member, a top plate 30 secured to the anchor plate for relative movement therebetween, and against spring means 60, electrical alarm means 86, 87, a multi-position switch 90 for actuating the alarm means 86, 87 and having spaced apart contacts series connected to the alarm means, and a plunger rod 40 completing a circuit between the contacts when in a first position and maintaining an open circuit when in a second position, resilient means 41 biassing the rod to the first position and latch means 54, 92 for holding the rod in the second position and being releasable upon relative movement of the top plate 30 and the anchor plate 28. As shown, the device is mounted on a top rail 21 of a lower sash 22 adjacent to a side member 24 of an upper sash 26 and comprises a cover 39. An inner member 38 of the top plate 30 is formed with recesses 70, 72 for batteries 74, and is provided with a pair of switch contacts 90, a cavity 85 for an alarm generator 86 and with an alarm device 87. The plunger rod 40 is housed in a bore 80 and is normally biassed by the spring 41 so that a tab 92 is held by a catch 54 on a blade spring 56 in the anchor plate 28 to maintain the alarm device inoperative. The cover 39 is secured to the anchor plate by means of a screw 116 and by a pair of flanges 105 which resiliently engage under a spring fixed to the anchor plate. The cover is formed with a bore for a plug 34 carrying a locking bolt 100 which is engageable in a recess 120 in the sash 26. In use any prying or jimmying force between the sashes, moves the cover 39 and inner member 38 against the spring 60 and releases the tab from the catch 54 causing the rod 40 to move into a recess 112 in the plug 34 and completes an electrical circuit through the switch contacts to the alarm generator 86. When the plug 34 is unlocked to retract the bolt 100, the outer end of the rod 40 rides up a ramp 114 of the recess 112 and is thereby reset to the non-operated condition of the alarm. In another embodiment, Figs. 10-12 (not shown) the device is applied to a door and the lock bolt co-operates with a keeper on the door frame.

Title: Improvements in or relating to heat control systems for furnaces and the like
IPC: G05D23/00
Filed: 1928-01-23
Abstract: 309,246. United Glass Bottle Manufacturers, Ltd., and Moorshead, W. A. Jan. 23, 1928. Electrically-actuated valves.-In thermostatic control for furnaces and the like the temperature is maintained with respect to upper and lower limits, or a predetermined mean value, the arrangement being such that on one of these limits being reached, or the mean temperature passed, there is a rapid change (increase or decrease as the case may be) of fuel supply (or fuel and air), followed by a further change in the same sense but at a relatively slow rate, such change continuing either up to an extreme stop position, or until the other temperature limit is reached, or the mean temperature again passed, when the " rapid " control followed by the " slow " control is repeated, but in the opposite sense. The " rapid " control is designed to deal with small short period temperature variations; the " slow " control with long-period variations. The control may be effected by a single valve, Figs. 1, and 2, or by two valves in parallel, Fig. 3. In the first form, the valve operating shaft a is driven from a reversible motor through gearing comprising a " high " gear f, i and " low " gear g, j, k, i, one or the other being in action through the medium of a sliding jaw clutch m. The clutch is controlled by a cam driven from the motor shaft b and comprising a concentric path n and a short chord path o, the arrangement being such that passage of the cam follower from one end of the chord to the other moves the clutch from high to low gear and back to high. The cam drive includes a mutilated pinion r having in the mutilated sector two one-way pawl teeth u, engaging pins v on the driving pinion s. In the position shown in which the valve shaft a is being driven in low gear and the pinion r being in one of its end positions is stationary, on the temperature value towards which the motion of the valve is tending being reached, the motor is reversed, the lower pawl u becomes effective and the pinion r rotates anticlockwise. The gear is thereupon changed from low to high owing to the engagement of the concentric path of the cam path with the follower and the valve is thus moved rapidly until the pinion r, reaching its other end position, becomes stationary, having first, however, returned the gear from high to low. The slow movement of the valve is thus started and continues until the opposite temperature limit is reached, or the means temperature again passed, when the motor reverses and the operations just described are repeated, but in the reverse direction, or until the motor is stopped or rendered inactive by a safety limit device. In the form shown in Fig. 3, a quick motion solenoidcontrolled valve E is in parallel with a slow motion valve F operated by a motor drive G capable of reversal and designed to close slowly when the valve E shuts, and open slowly when the valve E opens. Preferably the valve E controls only a small proportion of the fuel supply (adjustable by a valve H).
