Title: Improvements relating to mechanism for controlling oven temperatures in gas heated cooking stoves or ranges
Inventor: PINKESS LESLIE HAYDN
IPC: F24C3/12
Filed: 1951-10-16
Abstract: 732,967. Thermally actuated valves. EVERED & CO., Ltd. Jan. 12, 1953 [Oct. 16, 1951], No. 24057/51. Class 135. Mechanism for controlling oven temperature in which a spring-loaded gas valve 10 is pre-set by a knob 19 through a lever 13 and is thermostatically controlled, e.g. by a thermal bellows or rod and tube, has supplementary control means which may, by the setting of a second knob 30a, be made to exercise no control over the setting of the valve or to coact with the valve to restrict opening of the valve to an extent preset by the supplementary control means. A setting spindle 18 has a pin-and-slot connection with a thrust rod 16 abutting the thermostatic means whereby rotation of the spindle positions a block 15 screwing on the rod and thus pre-sets the valve for a given oven temperature. Rotation of the spindle 18 also positions a block 26 screwed thereon and bearing on a lever 14 pivoted at 14a on a block 14b slidable on an adjustable rod 23. The block 14b rests on a spring 25a so that as the valve opens this block slides downwards due to the valve spring 12 pressing on the lever and overcoming the spring 25a. On rotating the knob 30a a cam 32a is moved from a recess 7f to fix the position of and prevent the block 14b and spring 25a from moving downwards, so that the valve can only open an amount determined by the preset position of the valve end of the lever 14. During heating up of the oven the valve is controlled through lever 13, but during cooking a constant predetermined heat input is ensured by the lever 14 locked in its preset position.

Title: Improvements in or relating to circuit arrangements for selectively causing a desired potential to appear at a desired point in the circuit
IPC: H03K17/52
Filed: 1947-02-14
Abstract: 636,700. Valve circuits. STANDARD TELEPHONES & CABLES, Ltd., McWHIRTER, E. M. S., DUNN, R. H., and LENNOX, P. W. Feb. 14, 1947, No. 24096. Divided out of 636,667, [Group XL (b)]. [Class 40 (vi)] A circuit comprises a number of branches which connect a common point via rectifiers to a number of control points which are also each connected via a low resistance path to a reference potential so that only when equal control potentials are simultaneously applied to all the control points is a control potential of equal value applied to the common point. The circuit may comprise a principal and a number of additional grid-controlled coldcathode gas-discharge tubes arranged so that a desired potential is applied to the control electrode of the principal tube only when all the additional tubes have been rendered conducting, the cathode of each of the additional tubes being earthed through a low value resistor with a point on each of these resistors connected via a rectifier to the control electrode of the principal tube. The Figure shows a circuit comprising a principal tube 26 and a series of additional tubes 21 to 25, the cathodes of which are earthed via resistors 27 to 31. When any one of the additional tubes, e.g. tube 21 is rendered conducting by a positive potential applied to its anode and control electrode the anode current flow causes the potential between the tapping point on its cathode resistor 27 and earth to increase positively, but since rectifier 32 is reversely connected and presents an impedance of say 20 megohms the positive voltage applied at the control electrode of the principal tube 26 is insufficient to cause this tube to conduct even when a positive pulse is applied to conductor 38. If all but one of the tubes 21 to 25 is rendered conducting the rise in voltage of the control electrode of tube 26 will still be very small. When however all the tubes 21 to 25 are conducting the voltage at the tapping points on their cathode resistors will be equal and therefore the conductor 37, and thus the control electrode of tube 26 will assume this value and the tube wall conduct when a positive going pulse is applied to conductor 38. In a modification, Fig. 1 (not shown), two additional tubes only are used, the tapping point on the cathode of one being connected via a reversely connected rectifier to the control grid of the principal tube and of the other via a resistor having a value which is high compared with the forward resistance of the rectifier but low compared with its backward resistance.

Filed: 1931-08-28
Abstract: 385,022. Induction relays and control of motors. ELECTROFLO METERS CO., Ltd. and ENGEL, F. V. A. E., Abbey Road, Park Royal, London. Aug. 28, 1931, No. 24226. [Classes 38 (iii) and 38 (v).] Following movement of control member.-A relay or balance mechanism adapted to be employed in a metering, indicating or regulating device in which variations in a physical characteristic such as the flow or pressure of fluid in a conduit are caused to vary the value of an electric current in a measuring circuit comprises an induction disc arranged so that it is normally balanced by forces depending on the current in the measuring circuit and that in a balancing circuit and circuit opening and closing means, such as a contact arm or one or more mercury switches rotatable with the disc for controlling the operation of an electric motor, by which a metering, indicating or regulating device is adapted to be actuated. As shown in Fig. 1 the induction disc 1 under the action of windings 2, 3 arranged to produce opposing torques carries a contact arm 5 biased to a central position between fixed adjustable contacts 6, 7 by a light spring 8. Normally the contact arm 5 remains midway between the contacts 6, 7 but on an increase or decrease of current in the measuring coil 2 the arm 5 is caused to engage one or other of the contacts 6, 7 so completing the circuit of a reversible motor in one or other directions. The operation of this motor produces a similar change in the current in the balancing coil by cutting out or inserting resistance in its circuit so that the contact member is again brought to the position shown and the motor circuit broken. As applied to an indicating system shown in Fig. 3 the motor 10 drives through gearing a movable contact 15 controlling a resistance 16 in the circuit of the coil 3, and also moves an indicator 11 over a graduated scale in accordance with changes of current in the measuring coil. In a modified form, Fig. 5 (not shown), a number of relay elements may be combined mechanically. In an application to the control of the flow of fuel to furnaces, Fig. 4, in order to maintain a predetermined relation between the flow of air through a pipe 23 to the flow of fuel through a pipe 21, the relay controls a motor 10 operating a damper 24 in the air supply pipe, the measuring and balancing coils 2, 3 receiving currents proportional to the flow of current in the pipes 21, 23. Specification 299,198, [Class 38 (iii), Electric motor control systems &c.], is referred to.

Abstract: 916,074. Scouring grain. MAIMON, A. July 14, 1959 [Dec. 29, 1958], No. 24232/59. Class 58. In scouring grain to remove bran, the grain is passed through a shoot 140 and between the outer cylindrical surface of a rotating drum 62, carrying helically arranged bristles 98, e.g. of nylon or brass, and the abrasive inner surface 60 of a cylindrical casing 28 rotating in the opposite direction to the drum. The drum is secured to a tubular shaft 16 mounted in bearings 18 and 20 on posts 12 and 14 and rotated by a belt-driven pulley 136. The casing 28 is secured to spoked wheels 24 and 26 rotating on the shaft 16, rotation being effected by a belt (not shown) engaging a groove 48 in the wheel 26. A circular plate 68a is secured to this wheel. The inner face 32a of the wheel 24 slopes, as shown, and carries a plurality of projecting fins 38, which are spaced around the wheel. The scoured grain passes through holes 58 in the casing 28 into compartment 154 of a trough 144 having another compartment 152 receiving cooling fluid, such as water, flowing over the outer surface of the casing. The drum comprises four similar segments detachably mounted on four rods 70. Each segment comprises a curved portion 64a and two flat side portions 66 and 68. The rods 70 can be moved radially to move the segments towards or away from the casing 28 by turning a camshaft 100 passing through the shaft 16, which cam-shaft is provided with four cam surfaces 104 with which the inner ends 106 of the rods, projecting through holes 78 in the shaft 16, are kept in contact, as by springs 88. The shafts 16 and 100 carry plates 122 and 112, which are clamped together by bolts 128 and 130. Adjustment of the space between the drum 62 and the casing 28 is effected by unclamping the plates and turning the plate 112. Each segment is provided with four guide rods 90, which are secured, at their inner ends, to the shaft 16 and have outer ends which are parallel to the supporting rod 70 and pass through a hole 96 in the portion 64a.

Title: Television projection apparatus
IPC: H04N5/74
Filed: 1953-09-03
Abstract: <PICT:0725106/III/1> <PICT:0725106/III/2> Relates to television projection apparatus of the type described in Specifications 696,615 and 698,107, [both in Group XL(b)], in which the light flux from a separate light source 5 is modulated by means of a Schlieren optical system including a rotating parabolic reflector 1 carrying a thin layer of viscous liquid scanned over an image field 8 by a cathode-ray beam 7.  In such apparatus the liquid is subject to a "fatigue" which is stated to be due to alterations in the electrical properties during scanning and it becomes necessary to rest the liquid for a period before re-use.  According to the invention there is provided a fluid circuit driven by a pump 28 whereby the liquid after passing through the image field 8 is removed from the reflector surface and replaced by a new layer dispensed through a scavenging nozzle 20.  The reflector is inclined at an angle and the removed liquid accumulates at a region 27 from which it flows to bowl 26 communicating with the fluid circuit.  The circuit includes a storage tank 29 and its capacity is chosen to allow the liquid adequate time to regenerate.  Following the scavenging nozzle is a smoothing rake 30 for bringing the liquid to the correct thickness.  The thickness may be set by adjustable paws 23.  Fig. 2 illustrates in detail a section through the scavenging nozzle and rake.  Fresh liquid under pressure from pipe 45 enters cavity 44 and emerges in the direction of arrow 46 in such manner as to peel off the liquid layer 47 adhering to the reflector surface 41 coming from the left.  A small amount of the fresh liquid issues to the right and forms the new surface 50 at a thickness set by the rake 30.  Surplus liquid accumulates at 51 and returns to the fluid circuit.  Where fluctuations in the pressure of the fresh liquid can be eliminated, the function of the scavenging nozzle and rake may be combined.  To prevent liquid passing round the ends of the nozzle and creating a ridge at the reflector edge and in the centre, the nozzle and rake are made sufficiently long to extend over the edge of the reflector and bowl 26 at the centre. In an alternative arrangement, Fig. 3 (not shown), the reflector edge is formed with a groove to collect liquid passing the end of the nozzle.  The liquid circuit may be operated intermittently.
