Title: Improvements in and relating to ultra short wave devices
IPC: H04L27/04
Filed: 1939-05-31
Abstract: 533,500. Cathode-ray tubes ; electron oscillators. BRITISH THOMSON-HOUSTON CO., Ltd. May 31, 1939, No. 16051. Convention date, June 1, 1938. [Class 39 (i)] A cathode beam is velocity-modulated by an electrode system and allowed to proceed until the velocitymodulation is transformed into density-modulation as described in Specification 518,015 ; the density-modulated beam produces oscillations in a second electrode, which are fed back to the velocity-modulating system. Fig. 1 shows an arrangement comprising a tubular container 10 having metal rings 20 on its inner surface connected to a high positive of potential. A beam is produced by an electron gun 13 and focused by coils 25. Velocity modulation is produced by an electrode 35 surrounding the tube and an electrode 30 enclosing the electrode 35 and provided with end walls 31, 31<SP>1</SP>. Oscillating potential applied to these electrodes produce velocity modulation as explained in the above-mentioned Specification. The beam then proceeds until the velocity-modulation is converted into density-modulation, when it enters a pair of electrodes 39, 40 similar to the electrodes 30, 35 and connected to them by coaxial conductors 44, 45. The conductors 44, 45 form with the electrodes a resonant system whereby the oscillation produced in the electrodes 39, 40 by the beam are fed back to the electrodes 30, 35. Energy is abstracted, from the beam as it passes through the electrode 40 by means of an electrode 47 and a co-axial transmission line 48, 50, or a separate set of collecting and transmitting electrodes may be provided. Modifications are described in which the co-axial conductors 44, 45 are replaced by conductors surrounding the tube, which conductors in some cases also function as the velocity-modulating and feed-back electrodes. Reference has been directed by the Comptroller to Specification 523,712.

Abstract: 871,010. Automatic temperature control systems. HAGAN CHEMICALS & CONTROLS Inc. May 12, 1959 [May 19, 1958], No. 16293/59. Class 38 (4). [Also in Group XXIX] The discharge by-pass valve of a centrifugal boiler feed pump is controlled in accordance with the temperature difference at the inlet and discharge of the pump so that, at low demands for feed water, there is maintained a rate of flow through the pump which is substantially proportional to the said temperature difference. Thermocouples are located at the pump inlet and outlet and are interconnected to provide a voltage signal proportional to the difference in the detected temperatures. This signal is fed to the A.C. chopper 37, Fig. 2, of a constant gain amplifier unit 23, 38. The output signals from the transformers 60, 61 are rectified and transmitted to two coils 67, 68 secured to a resiliently suspended member 75 and located in the air gap 70 of a magnetic core 69. The member 75 is connected by a rod 72 to a force balance beam 73 of a pneumatic signal generator (see Group XXIX) which is connected to a pneumatic controller the output signal of which is transmitted to a relay valve which in turn transmits a signal to the diaphragm-actuated valve controlling the by-pass flow of the pump.

Abstract: 1,135,558. Semi-conductor devices. RADIO CORPORATION OF AMERICA. 18 April, 1966 [26 April, 1965], No. 16825/66. Heading H1K. In a transistor having a low collector capacitance, a limited portion 36 of the collector region adjacent to the base region 38 and lying directly below the emitter region 40 is of lower resistivity than the remainder 14b of the collector region, Fig. 9. A plurality of transistors are produced by growing an N-type silicon epitaxial layer (14) on an N+type substrate (10), Fig. 2 (not shown), thermally growing an oxide layer (18), Fig. 3 (not shown), etching windows (22), (24) in oxide layer (18) and vapour depositing layers (26) of antimony on to the exposed surfaces, Fig. 4 (not shown). A second oxide layer (28) is then grown, the oxide growing faster in the windows than over the remainder of the surface so that the thickness of the epitaxial layer (14) is reduced at these points, Fig. 5 (not shown). The oxide layers (18), (28) are removed by etching, exposing depressions (30), Fig. 6 (not shown), and a second N-type epitaxial layer (14a) is grown, depressions (30a) being formed in its surface above the previous depressions (30), Fig. 7 (not shown). The wafer is then heated to diffuse the antimony layers (26) into the epitaxial layers (14), (14a) to form the low resistivity portion (36) of the collector region (14b), Fig. 8 (not shown). P-type base region 38 and N-type emitter region 40 are then diffused into the wafer, the emitter region being located directly above region 36 by means of the depression 30a. Base and emitter leads may be connected by means of evaporated metal layers and substrate 10 may form the collector contact. The semi-conductor material may also be germanium.

Abstract: 202,250. Wade, H., (Nash Engineering Co.). March 10, 1922. Pumping-apparatus; regulating; starting, facilitating. - Pumping - apparatus 10, particularly adapted for use with vacuum steam heating systems. as described in Specification 200,150, comprises air and water exhausting pumps, each connected with a receiver 12 having in its inlet pipe 16 a restricted portion 17 of such size that the quantity of water passing therethrough cannot exceed the capacity of the liquid pump to exhaust the same. By this means flooding of the receiver 12, and consequent passage of water through the air pump, are avoided. A gravity-operated non- return valve 21 in the pipe 16 prevents the backflow of air and water from the receiver to the return pipes 19, 20 of the heating system. The inlet pipe 14 of the air pump is connected to the top of the receiver, while the inlet end of the priming pipe 15 for the liquid pump is situated below the inlet end of the inlet pipe 13 for the liquid pump. Further, the outlet end of the pipe 16 is well above the inlet of the pipe 15, so that sufficient priming liquid remains in the receiver in the event of the valve 21 leaking. The leads 22 of the electric motor 11 driving the pumps are connected to the mains 23 through a hand-oparated knife-switch 24 and a pressure-controlled switch comprising a magnetically-operated switch 25 and a diaphragm pressure relay switch 26 connected by a pipe 27 with the return pipe 19, the pressure in which opens or closes the motor circuit.

Abstract: 297,787. Sullivan, Ltd., H. W., and Griffiths, W. H. F. June 28, 1927. Condensers of the interleaving plate type, wherein the plates of one set are arranged adjacent and in fixed relation one to another, so that the dielectric gaps between the opposite faces of two adjacent plates of this set and the opposite faces of an interleaved plate of the other set are complementary for all positions of the latter plate have the plates so connected that for each pair of adjacent fixed plates between which a movable plate is located, the dielectric gaps between opposite faces of the movable plate and the adjacent faces of the fixed plates are electrically in series, The advantage of this is that variations of the dielectric gap due to want of alignment, bent plates, or other causes do not upset the calibration, as they do in condensers in which the gaps are in parallel. The fixed plates are in two sets 11, 12 and the movable plates 13 are all insulated from one another on the shaft 14, so that between a movable plate and adjacent surfaces of adjacent fixed plates there are two dielectric gaps 16, 17 in series. Fig. 2 shows a form wherein capacity effects between the non-engaging parts of the movable plates are reduced by dividing each fixed plate into two and separating the parts as 11a, 11b or 12<a>. 12b by an annulus 18 which is electrically connected to the plate parts of the fixed plate. For the same purpose, the moving plates are of such radial extent that they do not protrude in either direction beyond the fixed plates. The moving plates are therefore, formed of tinfoil covered, or silvered, insulating supports 19 on the shaft. glass being a suitable material. Fig. 4 shows a form wherein the movable plates are displaced alternately through 180‹ around the shaft, the co-operating parts of the fixed plates being similarly arranged. In this case the plates 18 may be dispensed with, and the parts of the fixed plates made to overlap slightly or the parts may alternatively be formed integral but spaced from one another lengthwise of the spindle. In a modification of the form shown in Fig. 2, the plates 11, 12, 18 may be formed in one relatively thick piece with a thinner screening part extending therefrom. The Specification refers to various laws the condenser may follow.
