Patent GB-318526-A (GB)
IPC: H01J19/68
Filed: 1929-09-04
Abstract: 318,526. British Thomson-Houston Co., Ltd., (Assignees of Zehner, J. L., and Acheson, M. A.). Sept. 4, 1928, [Convention date]. Vacuum tubes; lowpressure metallic vapour apparatus. - In a valve in which the discharge current tends to be limited by space charge, material, which on heating forms a space charge reducing vapour, is disposed on a part other than the cathode, having a large area and preferably on the anode, means being provided for controlling the temperature of the part so that the material, when heated, forms a vapour enabling positive ions to be produced by collision with electrons. The material may consist of an amalgam, an alkali metal such as caesium or rubidium, or iodine; it should not be present in the valve in liquid form. As shown, the anode 1, consisting of copper or silver, which readily forms an amalgam, is surrounded by a jacket whereby the anode may be cooled or heated, as by a liquid or an air blast. The anode is sealed to an upper portion 2 of material known by the registered Trade Mark " Pyrex," and the seal is protected from heat radiation by a conical shield 5 having an inturned upper edge. Mercury, previously purified by distillation, is admitted to the valve from a vessel 7; preferably the mercury is introduced into the vessel in a closed capsule 9 and held in an upright position while the vessel is sealed to a side tube 6. The valve is shaken so that the capsule strikes a ridge on the bottom of the vessel and is broken so as to release mercury, which is heated by the operating current of the valve or from an external source. After the anode has been amalgamated, the side tube 6 may be sealed off. A heat absorbing enclosure may be arranged around the glass part 2 in order to ensure condensation of the vapour producing material on the anode. Specifications 15975/12, 15788/14 and 309,442 are referred to.

Abstract: 533,931. Fungicides. ROHM & HASS CO. Oct. 2, 1939, No. 27026. Convention date, Dec. 10, 1938. [Class 81 (i)] [Also in Groups XXXVI and III] Yellow cuprous oxide having fungicidal properties and useful in antifouling paints is prepared by anodically oxidizing copper in a bath which contains a lyophilic protein colloid such as glue, gelatine, blood or egg albumen or casein. The copper anode is separated from the cathode which may be copper, platinum, stainless steel or graphite by a porous diaphragm of asbestos, cotton, parchment, alundum or ceramic ware The electrolyte is an aqueous solution of sodium or potassium halide to which a small quantity of soda ash or caustic soda may be added. Alkalinity is maintained during the process, and additions of the colloid are made as it is used up. The bath is maintained at 50- 100 C. The oxide is obtained as a sludge which is filtered, washed, mixed with a solution of the colloid, again filtered and dried. Specification 523,736 is referred to.

Filed: 1937-10-06
Abstract: 487,370. Timber buildings. ROE, R. D., and HARTT, C. H. Oct. 6, 1937, No. 27059. [Class 20 (iv)] A wooden main or division wall is formed of solid wooden panels having plain flat ends which are engaged by stepped or channel-section sole and cap members, which locate and position the panels, and which present flat outer faces to abut against the ceiling joists or footings. Each panel comprises solid wooden core members 21, Fig. 2, having tongue and grooved side connections, one face of the panel being provided with bracing members 28 to which are secured the lining sheets 32, while the other face is covered with a layer of building-paper and vertical weatherboarding 26. For division wall panels both sides are covered with bracing members and lining sheets. The end members of the panels are also formed with tongues and grooves whereby the panels are joined together. The upper ends of the panels are received into the grooves of channel-section sill members 36 which are continuous, and which may be formed from solid wood or, as shown in Fig. 10, may be fabricated from battens. The sole members 37 for the main walls are stepped and their upper surfaces may be covered with metal flashing 75 ; the sole members for the division walls are of channel section. Both the sole and sill members may be formed of metal instead of wood. The sole members are supported on concrete footings 74 having air gratings 90, and weather strips 92 are secured in grooves in the lower sides of the sole-plates. The corner joints for the walls are stiffened by interfitting battens 48, 49, Fig. 4, and are covered by angle-section cover-pieces 51 ; the corner joints may be further strengthened by metal angle-pieces secured to the mitred ends of the sill members. Where a division wall abuts on a main wall, the lining of the main wall is cut away, so that the side of the divisional panel abuts directly upon the sides of the core members of the main panel, and the sill members are joined on their upper faces by T-shaped flat metal -connectors. Certain panels have interrupted core members for the reception of window and door frames, and a door panel for an outer wall may be formed with a grooved fabricated sole member to receive the edge of porch-flooring. The joists 53, Fig. 16, for an upper floor are grooved to receive the sill member 36 of the lower panels, and the space left between the upper sole member 83 and the lower sill member is filled in by weatherboarding 84. The horizontal and inclined roof beams are also grooved at their ends to receive the upper sill members of the wall panels.

Abstract: 1,046,845. Filter networks. SIEMENS & HALSKE A.G. June 2 , 1965 [June 29, 1964], No. 27387/65. Heading H3U. A filter arrangement of the type for splitting a wide-frequency band signal into a plurality of sub-bands or for combining a plurality of subbands into a single wide-frequency band signal, and including a plurality of band-pass filter sections with different frequency pass-bands, any two sections whose pass-bands are adjacent one another having a region of frequency response overlap, wherein, in accordance with the invention, said filter sections are directly connected at one side in parallel or series to a common input and are such that, considering a part of the region of frequency response overlap of any two sections whose pass-bands are adjacent one another, the values of the characteristic functions of these two sections have an approximately reciprocal relationship with one another in said part of the region, and such that the blocking attenuations of all of the filter sections which block a particular frequency are of such magnitudes that the real components of the input admittances of these filter sections have no appreciable effect on the real component of the input admittance of the section or sections passing said particular frequency. It is thereby ensured that the input admittance presented to the common input is at least approximately constant throughout the full frequency band. Compensation of the reflection factor at the band limits may be effected by providing a low-pass filter and a high-pass filter and making the pass-band of the low-pass filter adjacent the pass-band of the band-pass filter passing the lowest frequency band and the pass-band of the high-pass filter adjacent the pass-band of the band-pass filter passing the highest frequency band; alternatively, the compensation may be effected by two additional band-pass filters having passbands similar to the pass-bands of the low and high-pass filters. The Specification describes the underlying theory.
