Abstract: 342,074. Thermionic valves and generating circuits. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Nolte, H. J. ; 1710, Rugby Road, Schenectady, New York, U.S.A.) Dec. 11, 1929, No. 38029. Convention date, Dec. 24, 1928. [Classes 39 (i) and 40 (v).] In thermionic devices such as transmitting valves, a conduit conveying cooling fluid is movable into a position to direct the fluid against a heated portion of the evacuated e n - velope of the device, the conduit also controlling the circuit of an electrode to ensure that the envelope is cooled when the electrode is energized. In a valve with an external anode 2 and with a reentrant tube and pinch 3 for filament conductors 4, a rigid insulating tube 15 moves together with a switch 18 about a pivot 17 so that, when the switch is closed, the nozzle 14 of the tube 15 is moved on to a bushing 13. Air or other cooling fluid is then supplied from a pump connection 16 to a rubber tube 12 applying the air to the inside of the seal 3 and to the conductors 4. The air emerges through apertures in a metal cap 10 carrying insulating bushes 11 for the filament leads 5. The switch 18 may control the energization of a relay 20 from commercial mains, the relay closing the filament circuit. Alternatively, the grid or anode circuit may be controlled. To ensure that the air-pump motor is started, its control switch may be synchronized with the switch controlling the highvoltage supply to the anode.

Abstract: 992,865. Ionization counter. GENERAL ELECTRIC CO. Oct. 9, 1962 [Oct. 11, 1961], No. 38177/62. Heading H1D. To increase the sensitivity of an ionization vacuum gauge, ion-collector photocurrent, due to soft X-rays generated at the anode 9 of the magnetron-type ion source 4, is reduced by utilizing as the ion-collector a dynode 8 of small angular size on to which electrodes 15, 16, 17 and 19 accelerate and focus an ion beam and which forms the first dynode of an electron multiplier 18. Photo currents due to cathode radiation are reduced by using a lanthanum boride cathode filament at 675 C. The electrode 15 is in the form of a mesh or a honeycomb structure, but in another embodiment, Fig. 4 (not shown), it is replaced by an apertured diaphragm. Also, the anode cylinder 9 has a tapered restricting portion forming with the apertured diaphragm an electrostatic lens. The cathode may be a single coaxial filament connected to a support within the electrode 16.

Abstract: 1,163,002. Laminated light-transmitting element; moulding optical elements. KIRK OPTICAL LENS CO. Inc. 31 Aug., 1966 [6 May, 1966], No. 38788/66. Headings B5A and B5N. [Also in Divisions C1 and G2] A light-transmitting element comprises a body of rigid and infusible thermosetting material having chemically bonded to its outer surface at least one relatively thinner layer of glass or plastics material which is more abrasion resistant than is the thermosetting material. The thermosetting material may be an epoxy resin; a polysulphide/epoxide copolymer; an unsaturated polyester; a polyurethane; an unfilled silicone; or a ureaformaldehyde resin. When plastics is used as an outer layer it may be an allyl resin, e.g. allyl diglycol carbonate resin. In one method of making an element, e.g. an ophthalmic lens outer glass layers 14, 16, Fig. 3 are spaced by a gasket 18 to form a chamber into which liquid thermosetting material 12 is poured. Heat is then applied to cure the resin after which the gasket 18 is removed and the edges of the lens trimmed. The thermosetting material or the outer layers may be coloured. In a second embodiment, a thin layer of cellulose acetate, which may be tinted to act as a filter, is placed between the outer layers of the lens before pouring in the thermosetting material. In a further method, used to produce a varifocal lens, one outer layer 52 and a former 64 coated with release material are arranged as shown in Fig. 11c to form a chamber into which a thermosetting material 58 is poured, this material then being cured by heat. The former is then removed and a second thermosetting material of different refractive index is poured between the material 58 and the second outer layer 54 and cured. In another embodiment in which a multifocal lens is produced, the outer layers are arranged to form a chamber and a metal insert is placed between the layers before a thermosetting material is poured therebetween. After curing of this material the metal insert is removed and the space resulting filled with a thermosetting material of a different refractive index. The elements may be formed as lenses, is described above, as flat members, for use as windows, shelving or desk tops, or as curved members for use as windscreens, instrument dials or protective shields. They have high thermal stability and are thermally insulating. The thermosetting material may include a wire mesh. In another embodiment, Fig. 7, outer layers 40, 42 of glass, to which a layer of thermosetting material 38 has been secured by employing each of the outer layers separately as one wall of a mould chamber, pouring in the material 38 and curing it, are used together as the walls of a mould into which a material 36 which does not ahere to glass, e.g. a polysiloxane, is poured and then cured.

Abstract: 1339120 Frequency detectors COLTRON INDUSTRIES Inc 1 Dec 1969 [29 Nov 1968] 39115/72 Divided out of 1338999 Heading H3A The arrangements described are identical with those of the Specification 1,338,999, but the claims are directed to an apparatus for providing timed signals when the frequency of a first signal passes a threshold fixed by a reference wave, which apparatus comprises a coincidence detector receiving the reference wave and a logical control signal, a counting means responsive to the first signal and the reference wave developing the control signal when the first signal varies in the determined direction by a sufficient amount to pass the threshold, with a means responsive to the logical signal to produce the timed signals. Negative leading edges of reference square wave 40 clock a bi-stable A (detailed in Fig. 5, not shown) 4 also pass to diode 43 which with diode 44 forms an AND gate. Normally the Q output from A is "1" which causes bi-stable B to remain preset so that it will not respond to other inputs. As the reference wave goes 1 # 0, Q # 0 which allows B to receive negative going pulses. The first signal 46 is fed to bi-stable B and switches its "Q" output alternately "1" and "0". The output Q or B is capacitively coupled to preset terminal 9 of A therefore when Q # 1, a differentiated positive pulse forces A to reset temporarily thus causing B to reset until the next negative going excursion of the reference wave. When reference wave # 0, A is set, B is unlatched and counts 1 and 2, at which B presets A and in turn latching B &c. If the count of 2 by B occurs within the "0" part of the square wave 40, output from the AND gate 43, 44 does not occur. However, if a count of 2 arrives after the square wave # 1, the AND gate gives an output, whose pulse width and repetition rate are a function of phase and frequency difference.
