Title: Improvements in devices for converting heat into electric energy
IPC: H01J45/00
Filed: 1959-11-25
Abstract: 919,148. Thermionic converters. COHEN, H. Nov. 25, 1959 [Dec. 31, 1958], No. 40069/59. Class 39 (1). A device for converting thermal energy into electrical energy comprises a cathode and an anode spaced from one another, e.g. by a distance of 0.02 to 0.05 mm., with an evacuated space between them, and provided with terminals for connection to an external circuit. The cathode has a higher work function than does the anode, but preferably has discrete particles of lower work function dotted over its surface, and is maintained at a higher temperature than is the anode so that the cathode emits electrons which are collected by the anode which remains non-emissive. Suitable cathode materials, for operation at temperatures of 700- 1000‹ C., are W and Ni-plated Cu; Ta, Mo, Ni or Pt; W or Pt coated with a molecular film of O or H; or Ni coated with a molecular film of O. Suitable anode materials are oxidecoated metals, in particular a mixture of oxides of alkali metals and of alkaline earth metals. The discrete particles of lower work function on the cathode, which are perferably sunk into the cathode surface so as to be flush therewith, are preferably of the same material as the anode. As shown in Fig. 5, the cathode 8 is heated by hot fluids passing therethrough and the cylindrical anode 12 is provided with cooling fins 19. In an alternative arrangement a cathode traversed by a plurality of heating ducts, and having two active surfaces, is arranged between two planar anodes. Alternatively, the cathode 22, Fig. 10, may be heated by being placed in engagement with a hot surface, e.g. of a furnace. In further arrangements, Figs. 15 and 17, the cathodes 35, 43 are heated by solar radiation directed through window 39 and anode 36, and shutter 46 respectively. Alternatively, a planar cathode arranged between two planar anodes, one of which is apertured, to allow solar radiation to impinge on the cathode, may be mounted in a glass bulb. A plurality of converters may be electrically connected in series or in parallel, and, in the fluid-heated arrangements, may be arranged so as to be heated by the same fluid. Heat dissipated from the anode may be utilized in thermocouples or thermopiles.

A shaft-position control system for moving a lens in a weighing machine to a keyed position comprises coarse and fine loops each being of the type in which a member having conductive and non-conductive regions is moved relative to a set of contacts until a selected contact enters a " dead " zone. The coarse loop includes a helix 3, Fig. 1, which is arranged to be conductive except for a central, half-revolution long, " dead " region. The particular halfrevolution that the shaft 9 is to be driven to is determined by selecting one of 15 contacts 1 and by causing the shaft to be driven until the selected contact enters the " dead " zone. The fine loop includes a disc, Fig. 4, having conductive 30, 31 and non-conductive 23 regions and brushes 0-11, see also Fig. 2, the shaft being driven until a selected brush enters the dead region, 23 or 24, between the two conductive segments. To ensure that the fine displacement is correctly added to the coarse displacement the polarities of the voltages applied to the conductive segments 30, 31, are determined by whether an odd or an even numbered halfrevolution has been selected.

Title: Pulse length discriminators
IPC: H03K5/159
Filed: 1972-09-06
Abstract: 1434355 Pulse Circuits MARCONI CO Ltd 18 July 1973 [6 Sept 1972] 41236/72 Addition to 1159884 Heading H3P A pulse length discriminator comprises a multiple tapped delay device 12A, 12B of overall delay equal to or greater than a predetermined duration and having tapping distributed along the device, means 10 for applying input pulses to one end of the device, means 13 for deriving a first derived signal when signals are simultaneously present at all the tappings, and means 14 for deriving a second derived signal when a signal is present at the other end of the delay device 12A, 12B or when signals are simultaneously present at all the tappings distributed along portion 12B of the device. The discrininator further comprises a detector 15 responsive to the first derived signals for charging a charge storage means 16, a discharge switch 17 for discharging the charge storage means in the absence of a second derived signal, and means 18 for substracting a third signal, derived from the charge storage means, from the second derived signal in order to produce length discriminated output pulses. The discriminator may be used in a receiver of a pulse radar operated with a transmitted pulse length T. The discriminator will reject pulses of length less than 0À8T due to 0À8T delay provided by line 12B. Pulses of length between 0À8T and 1À8T are accepted and provide output pulses via AND gate 14 and subtracter 18 which will be shortened 0À8T. In absence of an output from the gate 14 an electronic switch 17 is closed to discharge a capacitor 16. When an output occurs from the gate 14 the electronic switch is open. Input pulses of length exceeding 1À8T are rejected since these input pulses cause outputs from AND gate 14 and from AND gate 13, which via a peak detector 15 charges the capacitor 16. The inputs from 14 and 16 to the subtractor 18 do not therefore produce an output at 19. At the end of the input pulse the output signal from AND gate 13 ends before the output signal from AND gate 14 so that the capacitor 16 will remain charged until the time when the electronic switch 17 is closed by ending of the signal at the output of AND gate 13. If discrimination against input pulses having a duration less than 0À8T is not required then the AND gate 14 may be omitted and the end of the delay line 12A, 12B is connected to resistor 11, electronic switch 17 and to the input of the subtracting network 18.
