Title: Improvements in or connected with the construction of aeroplane wings
IPC: B64C3/00
Filed: 1930-05-01
Abstract: 347,488. Aircraft planes. BOULTON & PAUL, Ltd., Riverside Works, and NORTH, J. D., Hill House, Eaton Hill, both in Norwich. May 1, 1930, No. 13439. [Class 4.] Aeroplane wings, ailerons, &c., comprising transverse diaphragms carried on spars, have bent metal sections with beaded borders sprung into notches in the diaphragms to form the curved portions of the wing section. Fig. 1 shows an aileron in which composite diaphragms consisting of plates 1, 2, 3, connected by stays 4, 5, 6, are secured to the spar. Notches such as 8, 12 are formed in the plates 1, 2, 3 to take the beaded edges 10 of sections such as that shown in Fig. 3, the surfaces of which are flush with the stays 4, 5, 6 when in position so as to form a smooth support for a fabric covering. The sections are rolled so that they have to be sprung more open as they are fixed in position.

Title: Improvements in appliances for the treatment of the larynx with ultraviolet rays
IPC: A61N5/06
Filed: 1932-05-12
Abstract: 386,850. Discharge lamps. CEMACH, A., 88A, Mariahilferstrasse, Vienna. May 12, 1932, No. 13647. Convention date, May 18, 1931. [Class 39 (i).] An appliance for the treatment of the larynx with ultra-violet rays from a mercury-vapour lamp, the discharge space of which is arranged in a hollow permeable body such as of quartz glass, is characterized in that the hollow.body 2, with the enclosed lamp 3, is sharply curved and of such dimensions that it can be introduced into the larynx behind the epiglottis, whilst the arc produced is maintained in all positions of the appliance. One end of the body 2 fits within a metallic sleeve 1, the interior of which is separated from the body 2 by a partition 10. Cooling water flows via pipe 12 through the hollow body 2 and escapes through pipe 11. Current leads 6 are connected to the lamp, which, in the form shown, consists of a U-shaped tube 3, Fig. 3, of some suitable material such as quartz and containing mercury. The arc is started by tilting the lamp, the pressure of mercury vapour then sufficing to prevent the two mercury columns from coalescing. A small quantity of. gas, preferably a rare gas, may also be present in the sharply bent portion. The bore of the tube at the sharply bent portion may be narrowed considerably at one or more places. If desired, the hollow body 2 may be provided with an impermeable protective sleeve or coating 15, emission of rays being thereby restricted to the extreme end of the lamp. Alternatively, the greater part of the hollow body may be rendered opaque, a separate tip of transparent material being fitted. Types of lamps other than that shown may be employed. Thus, the discharge vessel which may be U-shaped, may contain a rare gas such as neon in addition to a drop of mercury, and one of the two electrodes may take the form of a hot electrode.

Title: Improvements in and relating to methods of and apparatus for purifying quartz
IPC: C03B19/09
Filed: 1926-06-01
Abstract: 252,747. British Thomson-Houston Co., Ltd., (Assignees of Thomson, E.). June 1, 1925, [Convention date]. Induction furnaces. -Apparatus for fusing silica comprises a crucible 8, preferably of graphite, built within a resistor 14 and rotatively supported by shafts 10, 11 journaled in a frame 12. The lower shaft 11 is mounted on a thrust bearing 13 and is driven by a belt 27. The resistor 14, which may be of tungsten or molybdenum, forms part of the secondary circuit of a transformer, the circuit being completed by segments 15 forming the exterior casing of the crucible structure and by conductors 16 which surround the iron core 17. The primary windings 18 are connected to the supply circuit through brushes 22 and slip rings 19, 20 on the shaft 11. The structure is surrounded by a shield 26, and heat-insulating material 28 surrounds the resistor 14. Hydrogen or other suitable gas may be conducted through passages in the shaft 11 in order to avoid oxidation of the heater parts or of the fused mass. In a modified construction, the primary elements of the transformer surround the crucible which is covered by a plate of clear quartz to enable the progress of the fusion to be observed. In use, fragments of rock crystal are packed into the crucible and brought to fusion by progressively raising the temperature to about 1700 C. The apparatus is then rotated at about 1500 revolutions or more per minute. The fusion X assumes a cylindrical shape and the gas bubbles or impurities come to the inner surface of the cylinder. Rotation of the apparatus may then be stopped and heating continued so that the cylinder forms into a solid ingot with the frothy mass on top. The upper impure layer of quartz may be cut off by a band of copper or other metal charged with abrasive.

[Classes 40 (i) and 118 (i)] [Also in Group XXI] An automatic alarm system, shown as a firealarm system, comprises a breakable cord TA or TB stretched around each of a plurality of localities A, B to be protected. Each cord embodies fusible links VL or combustible sections, and is tensioned by a weight V or otherwise. Attached to each cord, as by a pulley HA, HB is a wire a, b connected, in an indicator box R, to a movable pulley BA, BB. A cord W stretched over the pulleys BA, BB is tensioned by a weight L, to which is connected the cord D of a weight-operated alarm bell K. When any cord TA, TB is broken by fire or other agency, the corresponding pulley BA or BB is released, its movement providing an indication of the locality of the fire. At the same time, the weight L is released and operates the bell K and, if desired, a switch in an external alarm circuit. Where a considerable number of breakable cords is used, the pulleys BA, BB may be arranged alternately at opposite ends of the box R, which may have partitions supporting the pulleys, and a glass door. Movement of a pulley BA, BB, when its corresponding cord breaks, may serve to actuate a switch arranged in the circuit of an electric locality-indicator, across which an electric alarm signal may be shunted.

Abstract: The slide ring packing on the shaft of a centrifugal machine, e.g. a centrifugal pump, is arranged in a packing chamber of the machine casing of the centrifugal machine and has elastic bellows (8). The bellows (8) surround the shaft (1) which extends through the packing chamber (4), and by exerting axial pressure presses two packing rings (12, 15) against one another. The bellows (8) at their rotor-side end are secured close to the rotor and corotate therewith. At the other end (11) the bellows (8) carry one (12) of the two packing rings which bears on the other, stationary, packing ring (15). Employing a slide ring packing of this type prevents rotor of the centrifugal machine from being subjected to excessive heat. <IMAGE>
