Title: Thermionic oscillation generators
IPC: H03B5/10
Filed: 1926-09-01
Abstract: 276,832. Kirke, H. L. Sept. 1, 1926. By varying inductance.- In order to maintain the oscillation frequency substantially independent of the valve characteristics, the necessary phase reversal of the feed-back from the anode to the grid circuit of an oscillator valve is secured by the aid of an auxiliary valve, and the anode circuit of the oscillatory valve comprises resonant means of low impedance relatively to that valve. The Specification describes the invention with reference to an oscillator valve having a tuned anode circuit and contains a mathematical analysis of the circuit conditions necessary to maintain oscillations. In Fig. 5 the tuned anode circuit is replaced by a mechanical vibrator such as a tuning fork T coacting with a plate coil L7 and grid coil L8 respectively. The resistances R1, R4 may be replaced by inductances provided the reactance is large compared with the differential resistance of the valve for the frequencies concerned, and in general any suitable combination of resistances, inductances and transformers may be used provided that the voltage changes applies to the grid of the oscillator valve VI from the plate of the auxiliary valve V2 are approximately 180‹ out of phase with the plate voltages of the first valve.

Title: Improvements in tunnel kilns
IPC: F27B9/08
Filed: 1929-07-19
Abstract: 340,271. Tunnel kilns. WOODALLDUCKHAM (1920), Ltd., and DUCKHAM, A. M., 136, Victoria Street, London. July 19, 1929, No. 22260. [Class 51 (ii).] In an open-ended tunnel kiln, air entering at the ends is diverted into flues in the walls by the draught of the kiln or of a suction fan, the wall flues at the inlet end for the goods being other than the usual exhaust flue provided at this end. In an annular kiln, which is shown developed in Fig. 2, the air entering the inlet end A passes through ports a into wall flues b connected to the chimney flue c. At the exit end F the air similarly passes through ports f to flues g, from which they are drawn bv a fan and delivered to flues h. From these flues the air passes through ports j to a roof flue r, and is used in part for combustion in the flues l, and in part for drying and preheating the goods in the inlet portion of the kiln. The combustion products from the flues l pass into the through tunnel damper-controlled ports l<1>, and are withdrawn through ports n and passed to wall flues o under control of dampers n<1>. Radial and circular flues may be provided in the travelling platform for the bottom heating of the goods, and the platform may have walls for preventing, to a large extent, contact between the goods and the heating gases. The platform may have openings for the escape of steam from the drying zone, and these are automatically closed when the goods reach a certain temperature by tiles supported on fusion cones.

Title: Improvements in or relating to automatic gain control for radio, television or like receivers
IPC: H04N5/53
Filed: 1945-08-29
Abstract: 613,026. Automatic gain control. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 29, 1945, No. 22274. Convention date, Aug. 29, 1944. [Class 40 (v)] In an automatic gain control system, the control voltage is derived from a point of positive potential via means for subtracting a constant voltage and a limiter is used to reduce the effect of noise on the gain control. As applied to the reception of television signals in which the maximum carrier amplitude occurs during the synchronizing period, I.F. signals from the stage 14 are rectified in the full-wave circuit 17 which includes the limiting diode 33. The limiter 33 is connected between the signal rectifiers 18, 19 and the load impedance 34, 38, the limiting level being determined by the negative bias applied to the system through the resistance 23. In order to render the diodes 18, 19, 33 conductive in the absence of signals, a further negative bias is applied to the cathodes 35, 36, over the resistance 46. Series and shunt inductances 39, 38, 41 may be employed to correct frequency-distortion of the video signal, which is applied to the amplifying stage 44 and over the lead 54 to the A.G.C. system. The anode of the valve 51, which is biassed to cut-off in the absence of signals, is connected to a source of positive potential over the resistance 61. A potentiometer comprising the gas-discharge tube 66 and the resistance 69 is connected between a source of negative potential and the point 76, the control potential being taken off through the filter 71, 72, from the point 74. The potential of the line 68 in absence of signals is adjusted by means of the potentiometer 62. In the presence of signals, conduction in the valve 51 during peak synchronizing periods causes the potential of the point 76 and thus of the line 68 to fall.

Filed: 1960-06-27
Abstract: 894,002. Educational appliances. VAN BAERLE, F.C.G. June 27, 1960 [June 26, 1959], No. 22460/60. Drawings to Specification. Class 146(2) In a nuclear reactor simulator, a transistor is heated from an external, controlled source. The transistor leakage current increases exponentially with temperature and is dependent on collector dissipation, itself dependent on leakage current. For a leakage current exceeding a given level the collector dissipation is such as to raise the leakage current above the stability valve and the current rises rapidly in a manner analogous to a reactor reaction which proceeds beyond criticality. The leakage current is assumed to be a measure of the nuclear reactivity of a reactor that is, its neutron flux density or generated power. The heating supplied to the transistor is manually controlled by means of switches and resistors and adjustment of these simultaneously positions the control and safety rods of a model pile. Visible and audible warning devices are also operated when the safety rods are moved into the model.

Abstract: 1,127,844. Turbines. BENDIX CORP. May 15, 1967 [May 19, 1966], No.22480/67. Headings F1G and F1T. The turbine starter of an aircraft engine is controlled by the circuit shown in the Figure so that when a predetermined speed is reached a relay 44, 44s is operated to turn the starter off, e.g. by shutting off its fuel or air supply. A signal representative of the starter speed is provided by a rotating wheel 15 associated with a magnetic pick-up 12 whose output is fed to the anode-cathode circuit of a silicon controlled rectifier 20 through a rectifier 14 and also to the control electrode 20c of this rectifier through a circuit including a frequency responsive filter 16 having an output over a narrow band width corresponding to the predetermined speed. Below this speed (i.e. when initially starting) the rectifier 20 is blocked causing a transistor amplifier 35 to make a transistor 38 conductive and so pass a large current through the relay coil 44 from the aircraft battery 46. When predetermined speed is reached, the rectifier 20 is fired by the output from filter 16 and consequently transistor 38 is switched off to deenergize the relay 44, 44s and so disable the starter. A diode 32 maintains the rectifier 20 conducting until the starter speed has fallen below the predetermined value to ensure that a fresh starting cycle is not initiated, the members 20, 35, 38 resetting automatically in preparation for another starting cycle which is initiated by action of a starter button (not shown). Members 32, 35, 38 may be replaced by a relay (70) whose coil is controlled by the rectifier (120) and whose contacts (72) control the coil of the starter relay (144), Fig. 2 (not shown).

Title: Process for demetalling hydroformylation stage products
Inventor: CARTER CHARLES ELLSWORTH
IPC: C07C45/78
Filed: 1955-08-04
Abstract: At least one metal carbonyl is removed from the hydroformylation products, obtained by the reaction of an olefine with hydrogen and carbon monoxide in the presence of a metallic hydroformylation catalyst by passing the products, initially at a temperature below the decomposition temperature of the metal carbonyl with the lowest decomposition temperature, downwardly from the upper portion of an elongated separation zone containing packing material, passing steam upwardly from a point in the lower portion of the zone, passing inert gas upwardly from at least one point above the entry of the steam to cause cooling and condensation of the steam by contact with the hydroformulation products, the amount and pressure of the steam and of the inert gas being adjusted to heat the hydroformylation products at least to the decomposition temperature of the metal carbonyl with the lowest decomposition temperature so that at least one metal is deposited on the packing material.  In addition to the carbonyl formed from the metallic catalyst there may also be present in the hydroformylation product carbonyls of iron, nickel, chromium and molybdenum formed from the iron alloys used in the construction of the apparatus.  Cobalt carbonyl may be decomposed at a temperature in the range 74 DEG  to 100 DEG  C. and the other carbonyls at temperatures in the range 171 DEG  to 216 DEG  C.  If more than one metal is deposited the one of the carbonyl with the lowest decomposition temperature will be deposited nearest the top of the separation zone.  Suitable inert gases for use in the separation are, for example, hydrogen nitrogen, methane and natural gas.  Preferably the steam and inert gas are introduced at several points in the zone. The hydroformylation products fed into the separation zone may contain dissolved synthesis gas or may have it removed beforehand. In the example a mixture of carbon monoxide, hydrogen and olefines with cobalt 2-ethyl-hexanoate as catalyst is subjected to elevated temperature and pressure; a liquid phase containing aldehydes and carbonyls of cobalt of and of alloying metals such as iron, chromium, nickel and molybdenum is separated and passed to a demetalling tower, packed with pumice, where it is heated from an initial temperature of 38 DEG  C. to a final temperature of 171-216 DEG  C. by means of steam and inert gas; cobalt is deposited on the pumice near the top of the tower and other metals further down; cobalt may be recovered from the pumice by treatment with a dilute acid solution and used to make the 2-ethyl-hexanoate or other salt for use as catalyst in the carbonylation step.
