Title: Improvements in or relating to apparatus capable of indicating distortion or degree of impurity of wave form of an alternating current
IPC: G01R23/00
Filed: 1926-02-01
Abstract: 262,626. Graham, M., and Graham, A., (Representatives of Graham, E. A.), and Rickets, W. J. Feb. 1, 1926. Current meters.-Apparatus for measuring the degree of distortion of wave form of an alternating current comprises a variable inductance 2 and capacity 1, connected in parallel to form a tuned rejector loop circuit, and two coils 3, 3<a> of high mutual inductance and low resistance connected one in each of the two branches of the circuit, which are connected across the terminals C, D of the apparatus 10 to be tested. The coils 3, 3a are coupled to another coil 4 in series with a current meter 5. The circuit formed by the inductance 2 and condenser 1 is tuned to the fundamental frequency of the current to be examined. If this is of pure sine form the currents flowing in the condenser 1 and inductance 2 will be opposed in phase and produce no indication on the instrument 5. If, however, harmonics are present, the current in the two branches are unequal and an indication is obtained on the instrument 5 which is a measure of the deviation from the pure sine form. Adjustable resistances 8, 9 may be arranged in either the capacity or inductance branch or in both branches of the tuned loop circuit in order to assist in obtaining a zero reading of the indicating device for pure sine wave conditions. A single coil 6 is connected in series with the loop and is coupled to a coil 7 opposed to it magnetically and in series with the indicating instrument 5. The effect of the ohmic component of the currents in the coils 3, 3a is thus compensated. A thermionic voltmeter may be connected across the terminals C, D, and a frequency meter 13 may be connected across the generator 11. The capacity in the rejector loop may comprise two or more variable or fixed condensers 1, 1<a>, adapted to be connected in series or parallel.

A vehicle is at least partially supported on a plurality of air cushions, and comprises a vehicle body 1 (Fig. 1, not shown), a plurality of cells partially enclosing the cushions 2, each cell being open at the bottom and having a top part 4 from which depends a skirt 3, preferably flexible, encircling the cushion, and means connecting the top parts of the cells to the vehicle body, the arrangement being such as to allow the cells to move relative to the body and relative to each other. The connecting means may comprise parallel linkages 5, extending downwardly and rearwardly from the body 1, or linkages comprising front links extending downwardly and rearwardly from the body and rear links extending vertically when the cell is hanging freely (see Fig. 2, not shown) so that the cell will pitch nose up on striking an obstacle. Alternatively each cell may be attached either rigidly (Fig. 4, not shown) or through a universal joint (Fig. 5, not shown) to a rod 9 slidable in a guideway 10 in the body 1, or each cell may be connected to the body by parts 12, 13 of links (Fig. 6, not shown). Springs 5A and preferably dashpots are disposed between the cells and the body, and may also be arranged between adjacent cells. The cells may be arranged in a ring (Fig. 7, not shown) around a central space, air being supplied to each cell by a membrane forming ducting 21 whose lower aperture is FGHJ. Adjacent membranes are connected along EJ by a folded membrane to reduce leakage from the central space which is supplied with air either directly by a compressor 23, or from the cells by leakage under the skirts or through holes in the skirts. Alternatively air may be supplied to the central space above and the cells be supplied by leakage from the central space. The cover plates 17 may be replaced by an annulus formed either of flexible material or of rigid sections hinged together along the cell boundaries. Each cell may be divided into compartments by flexible partitions or by an air curtain, the air jets forming the air curtain preferably forming the only source of air. The vehicle may be propelled in any direction by raising the appropriate skirt to give a horizontal thrust, the skirts forming the cell walls may be movable to eater for movement of the centre of gravity, and may be resiliently mounted on the top plates by linkages or rods similar to those on which the top plates are mounted. The vehicle may be supported, in addition to the air-cushion, on tracks, wheels, planing surfaces, floats, hydrofoils or aerofoils. The skirt construction may be as described in Specifications 952,771 952,772, 958,996, 979,396 and 979,397.

Title: Method of soldering hollow bodies
IPC: B23K1/20
Filed: 1936-02-03
Abstract: 456,093. Making soldered pipe-joints. GLASER, A., 68, Stromstrasse, Berlin. Feb. 3, 1936, Nos. 3172, 3173, and 3174. Convention dates, Feb. 4, 1935, April 16, 1935, and Oct. 14, 1935. [Class 83 (iv)] In making soldered joints between telescoping tubular parts, such as the upper frame member and steering head socket of a bicycle or motor vehicle frame, the parts are coated with flux and solid solder of substantially lower melting- point than that of the parts is placed into a number of circumferentially spaced open pockets or cut-out portions in one of the parts. On heating the joint the molten solder flows by capillary action into the joint, the open portions permitting escape of gaseous matter from the joint. The tube a has a number of longitudinal slots to receive solder e, which is held in position by a reinforcing liner f provided with smaller slots g. The liner f is in this case soldered at h<1> to the tube a, during soldering of the tube a at h to the socket. The surfaces to be jointed are coated with a deoxidizer such as soldering fat or acid. In a modification the tube may be formed with slits having projecting tongues l which hold the solder and also permit of escape of gases. In a further form the tube may be formed with open slots to receive solder of slightly larger size which is pressed therein and so held by friction.
