Title: Improvements in electric welding
IPC: B23K9/10
Filed: 1941-11-13
Abstract: 554,687. Supply systems for welding arcs. LINDE AIR PRODUCTS CO. Nov. 13, 1941, No. 14604. Convention date, Oct. 3, 1940. [Class 38 (iv)] ] [Also in Group XXII] Two independent and separate welded seams in the same work piece are simultaneously effected by depositing a quantity of fusible mineral material over each of the seams, inserting one end of each of a pair of fusible metal electrodes into each quantity of the fusible material and connecting the opposite ends of the electrodes to the opposite terminals of a single source of current so that the current passes in series through the electrodes, fusible material and work. The fusible material may consist of unbonded granular material as described in Specifications 443,723, [Group XXII], and 438,855, [Group II]. A web S is simultaneously fillet welded at opposite sides to a plate P. by a pair of welding electrodes 10, 16 connected through a switch 22 to the opposite terminals of a source of direct or alternating currents. The feeding of the two electrodes may be automatically controlled independently by separate voltage responsive means. Such an arrangement is shown in Fig. 2 as applied to the welding of two heads H to a storage tank or pressure vessel. The electrodes 34, 36 are connected through adjustable reactances' 44, 46 to the ends of the secondary 42 of a transformer. A resistance 70 is connected in parallel with each electrode. The coil of a relay 68 is connected to the rod 34, and to an adjustable contact 72 of the resistance so as to impress a definite portion of the voltage drop between electrode 34 and work on the relay. Wherever the welding voltage exceeds a preselected value the relay is energized and the arms 74, 76 closed so that an auto transformer 66 with adjustable contact 82 is connected to operate the motor 62 to rotate the feed rolls 60 to advance the electrode 34. The electrode 36 is similarly controlled. Ground connections 96, 96<SP>1</SP> may be provided so that if one welding head completes its seam before the other it may be shunted out. The Specification as open to inspection under Sect. 91 states that the process applies to ordinary metallic arc welding. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to waveguide devices
Inventor: GENT HUBERT
IPC: H01Q21/08
Filed: 1954-05-19
Abstract: 892,970. Radio aerials. SUPPLY, MINISTER OF. April 6, 1955 [May 19, 1954], No. 14681/54. Class 40(7). A waveguide device comprises a linear array of at least one group of side-by-side rectangular waveguides extending between input and output apertures, an input section of each waveguide extending from the input aperture being of symmetrical cross-section about transverse and in-line axes, an output section of each waveguide extending to the output aperture having a larger transverse dimension than the symmetrical section, and a taper section of each waveguide tapering in the transverse dimension and connecting the symmetrical section to the output section, adjacent walls of the waveguides of a group being foreshortened from the output aperture so that apart of the output section has an enlarged dimension in the line of the array determined by the overall in-line dimension of the group. The Figure shows a linear array of side-by-side square waveguides 1 which are fed by an array of slots 2 in the narrow face of a feed waveguide 3. A dielectric quarter-wavelength slab (not shown) is inserted in each waveguide 1 across a diagonal and extends from A to B; at B the transverse dimension of each waveguide is enlarged and at point C alternate walls of the waveguide are discontinued so that pairs of adjacent waveguides merge into larger waveguides 6 which feed into a cylindrical mirror (not shown). In transmitting, the waveguide 3 feeds longitudinally polarised waves into the waveguides 1 where the polarisation is changed to circular by the dielectric slabs. The taper at point B de-circularises the waves but the merge into the layer waveguides 6 produces an equal and opposite effect so that the polarisation at the output ends of the waveguides 6 is circular. Circularly polarised waves of one band are received by the reverse process; for receiving circularly polarised waves of the other band a feed waveguide 7 is provided which communicates with the waveguides 1 by slots 8A in its broad face and corresponding slots in the waveguide 1. Tranverse plates 9 are provided at a distance a halfwavelength behind the slots 8A to shortcircuit transversely polarised waves travelling beyond the slots. The waveguide 7 absorbs cross-polarised reflections so that if the waveguide 7 is omitted transverse attenuators must be provided to absorb such reflections. The polarising slabs may be omitted so that the array then functions to receive orthogonally plane polarised waves at the slot array of the waveguides 7 and 3. Specification 750,600 is referred to.

Title: Improvements in the concentration or extraction of organic acids occurring in aqueous solution
IPC: C07C51/46
Filed: 1929-05-10
Abstract: 331,637. Soc. Anon. des Distilleries des Deux-Sevres. March 20, 1929, [Convention date]. Addition to 312,046. Drawings to Specification. Carboxylic acids; formic acid; propionic acid. -The process of the parent Specification is applied to the extraction from aqueous solutions of acids of the fatty series, other than acetic acid. In an example propionic acid is extracted by means of butyl propionate, and the extract is dehydrated by distillation with an entraining liquid consisting of a petroleum fraction boiling between 138-140‹ C. With water this forms an azeotropic mixture boiling at 90‹ C., while the propionic acid forms with it a second mixture boiling at 134‹ C., which when condensed separates into two layers on the addition of a trace of water. In a similar way, formic acid is extracted by means of amyl formate, and is distilled with normal heptane; water distils off with the heptane at 79‹ C., followed by formic acid and heptane at 79.5‹ C. The apparatus used is identical with that of the parent Applica. tion.

Title: Improvements in or relating to the coating of non-metallic surfaces with metal
IPC: H01G4/228
Filed: 1945-06-12
Abstract: In a method of making a paste for the coating of surfaces with a noble metal, a compound of the noble metal is dispersed in a combustible organic medium and then converted into the metal thus forming a dispersion of the noble metal in the medium.  The oxide of the metal, e.g. silver, is preferably used and may be added in suspension in turpentine to a solution of colophony in turpentine, the colophony reducing the oxide to the metal.  Lead resinate and boric acid, with or without ethyl silicate, may also be added to produce a flux on firing.  The paste may be applied to mica condenser plates and then fired at 500-550 DEG  C. with or without previous drying.  Specifications 558,714 and 566,718 are referred to.

Title: Radar simulation apparatus
IPC: G09B9/54
Filed: 1971-05-13
Abstract: 1359504 Radar simulators PLESSEY CO Ltd 6 April 1972 [13 May 1971] 14849/71 Heading H4D In a device for simulating vehicular borne radar apparatus and generating information corresponding to static environmental features there is provided a first storage device for information in rectangular co-ordinates, conversion means for producing the information in polar co-ordinate form adjusted to be relative to the vehicle's position and a second storage device having addresses corresponding to various bearings relative to the vehicle and wherein the radiuses of each set of polar co-ordinates are stored at the address which corresponds to the bearing of the particular set. Store MS holds x, y co-ordinates of points on, e.g., a coastline CL (Fig. 2, not shown), fed via register MSIR. The store is sequentially addressed by register MSAR and the co-ordinates read out via register MSOR together with information Z giving the height of the feature corresponding to each co-ordinate set. The height information is used by subsequent equipment to decide if the feature is obscured by other features having the same bearing. The co-ordinates are fed to device PME having subtractors S1, S2 which are fed with the co-ordinates x 2 , y 2  of the vehicle, which can be varied to simulate movement. The vehicle co-ordinates are subtracted from the x, y co-ordinates to give co-ordinate X, Y, relative to the vehicle. These are then separately squared in multipliers M1, M2, the results added and the square root taken to give R, the range to the corresponding point. Range R is divided by X and then converted to radian to give the bearing #. The signs of the subtraction process in S1, S2 are used to give a signal, QA, indicating the quadrant containing the point. Address register PSAR stores the values R, Z in store P-OS via input register PSIR at locations corresponding to # and the particular quadrant. Each location can hold several R, Z values corresponding to features with the same bearing. A signal on line BA causes the information in store P-OS to be fed out sequentially to the display apparatus.
