Title: Improvements in or relating to branch connections welded to the walls of vessels
IPC: B23K33/00
Filed: 1945-10-05
Abstract: 597,849. Uniting by fusion. BABCOCK & WILCOX, Ltd., and HARRIS, H. Oct. 5, 1945, No. 25948. [Classes 83 (ii) and 83 (iv)] Making steam generators.-In welding branch connections such as nozzles to the walls of boiler drums, Conduits or like vessels of substantial wall thickness by depositing weld metal in a welding groove at each side of the wall between an opening in the vessel and a part of the connection inserted in the opening, the base of the welding grooves is provided by an annular projection extending from the connection. Alternatively an annular projection may be added to the side of the opening after machining or such projection may be used together with a projection on the connection. The opening 1 in the vessel is flared at 4 to form a throat 3preferably disposed midway between the inner and outer surfaces of the drum and the annular projection 9, which is of such dimensions as to leave a small gap between its outer edge and the throat, may be filletwelded at 911 to the nozzle 8 or may consist of a tapered deposit thereon of weld metal, or may consist of a ring sprung into a circumferential groove thereon or may be integral with the nozzle. The inner end of the nozzle extends inwardly slightly beyond the inner surface 5 of the wall. The two grooves 11, 12' formed by the annular projection are filled with weld metal and a fillet weld 13 is made round the nozzle at the outside of the drum. The projection may alternatively be formed by giving the end portion of the nozzle an increased diameter and machining it to leave the projection or by machining the nozzle of normal thickness over a length somewhat greater than the wall thickness of the vessel but leaving the projection, the surface of this part beyond the outer surface of the vessel being curved outwardly and the normal diameter of the connection being obtained at a distance sufficient to enable the outer groove to be filled with weld metal, the weld being completed by covering the curved surface by a fillet weld. An annular pad or ring with an internal frustoconical surface may be arranged round the opening on the outside of the vessel wall and fillet welded thereto on its outer periphery and filled on its inner surface with weld metal.

Title: Improvements in methods of forming conductive patterns on insulating material
IPC: H05K3/38
Filed: 1956-08-28
Abstract: 832,229. Electroplating. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 28, 1956 [Aug. 30, 1955], No. 26243/56. Class 41. A process of forming conductive patterns on insulating material 1, e.g. for a printed circuit, comprises coating the material, which may be phenol formaldehyde resin, with an adhesive 3, applying a film of metal 4, e.g. copper, over the adhesive, e.g. by vacuum evaporation, applying a resist pattern 5 over the film 4, electroplating a metal, e.g. copper, on the exposed areas of the film 4, and removing the resist 5, film 4 and adhesive 3, e.g. by solvents, from the unplated areas. The material 1 may be apertured at 2, the plating extending from an area 6, 7 through the hole 2, and covering an area 6A, 7A on the opposite side. A corrosion-resistant metal, e.g. solder, tin, lead or zinc, is electroplated on the copper plating, before removal of the materials 5 ... 3. The adhesive 3, which is thermosetting, is applied by dipping or spraying and, after the plating operations, may be cured, e.g. by induction heating or by applying hot rollers to the conductive areas of corrosionresistant metal, in which case only the adhesive 3. beneath the plated pattern is cured., An example of a resist is asphalt base inks, which may be sprayed through a stencil or applied by a silk screen printing process. The electroplating of the copper may be preceded by a strike plating process employing a copper fluoborate bath at a pH of 3, a plating.time of 30 minutes at a current density of 10 to 50 amps. per square foot giving a coating 0.0005 inch thick, the copper then being built up in the same or another bath. The corrosion resistant coating, when of solder, is produced by plating using a conventional Sn-Pb bath for 15 minutes at a current density of about 30 ainps. per square foot to give a coating 0.0005 inch thick. The solvent for removing the asphalt base ink resist 5 is toluene and this may be mixed with a solvent for the adhesive 3.

Abstract: 520,778. Indicating proximity of earth or other bodies. STANDARD TELEPHONES & CABLES, Ltd. (Material Telephonique Soc. Anon.) Sept. 9 1938, No. 26382. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 3, 1939.] [Class 37] A cathode - ray oscillograph apparatus for indicating heights, depths, or for locating objects comprises a short-wave transmitter-receiver controlled by a voltage derived from the sawtooth waves of the time-base circuit which is respectively positive and negative during portions of the saw-tooth cycle of fast amplitude change and slow amplitude change so that the transmitter-receiver functions alternately as a generator and receiver during the positive and negative voltage periods. Fig: 1 shows a transmitter-receiver 1 having a directive aerial 3 supplied through a feed circuit 7 from a source 8, the indications being given on a cathode-ray tube 6. The sweep circuit 5 produces saw-tooth oscillations of the form shown in Fig. 2 by the successive charging and discharging of a condenser through a resistance, the charging portions A of the curves being of exponential form and the discharge portions B taking place in much shorter time. The time derivative of this curve is applied to the generator-receiver 1 and is of the form shown in Fig. 3. The generator-receiver is caused to function as a generator by the positive portions D and as a receiver by the negative portions C. As the portion C constantly increases, the weakening of the signals for a longer distance to be measured is compensated by the continuous increase of sensitivity. The signal received after reflection is applied to the modulation electrode of the cathode ray tube 6 in such a manner that the spot becomes brilliant and indicates the required distance on a scale 9. The aerial 1 and reflector 2 may be oscillated about a pivot so as to. be alternately directed downwards and horizontally. An indication of the shape of an obstacle such as a mountain in front of an aeroplane is thus obtained.

Filed: 1971-04-19
Abstract: 1351857 Photographic flash apparatus EASTMAN KODAK CO 19 April 1971 [7 April 1970] 26420/71 Addition to 1324705 Heading G2A The photographic apparatus described and claimed in the parent Specification No 1324705 is modified in that the socket rotating means is driven by energy storage means capable of storing energy which is sufficient, if necessary, to bring to the sensing position the lamps of at least two flash units successively received by the socket. Upon operation of the film wind mechanism, a sector member (not shown) having an energy storage spring rotates the socket 17 through slightly more than 630 degrees, and if no flashcube 21 is mounted is held in this position by the engagement of a pawl tooth 46 with pawl finger 62. Insertion of a flash-cube depresses pawl disc 44 to the dashed line position. The socket then rotates until an energized stocker in the flash-cube is snesed in a firing position as described in Specification No 1324705. If no usable bulb is present, rotation after 270 degrees is stopped by engagement of pawl finger 128 with pawl tooth 46. Removal of the flush-cube allows rotation of socket by 90 degrees until stopped by pawl finger 62, and a further flash-cube can be inserted. If the second flash-cube has no usable bulb, rotation of the socket through 270 degrees is again obtained.

Abstract: 1,215,959. Welding by fusion. GENERAL ELECTRIC CO. 4 June, 1968 [10 July, 1967(2)], No. 26634/68. Heading B3R. [Also in Divisions G1; H1 and H4] A charged particle beam apparatus for treating a workpiece, is provided with an electrode 15 for absorbing the energy of the beam when it is deflected off the work 13. In the electron beam welding apparatus shown beam sensors 25-27 are provided on three corners of the electrode 15 and two further beam sensors 31 and 32 are aligned with apertures 33 and 34 in the electrode. The electrode 15 is preferably of thick copper and may be cooled by coolant flowing through conduits 28. To adjust the beam position and focusing scanning waveforms from generators 56 and 57 cause the beam to scan the electrode (15 (Fig. 2, not shown) preferably non-uniformly so that the beam scans more slowly over the sensors, and the scanning waveforms are preferably non-synchronous so that the beam does not traverse the same path over the work 13. The outputs of sensors 26 and 27 are integrated over three second intervals in units 36 and 37 and compared in a comparator 38 controlling a current source 39 supplying a deflection coil 42; a discriminator 35 determines the sign of any change required and controls the current source 39 accordingly. This corrects the beam position along one axis, and the sensors 25 and 26 similarly control the beam position along the other axis. Focusing is controlled in a similar way in response to the output of sensor 31 which can be adjusted in position to correspond to the position of the workpiece. The second focusing sensor 32 is disposed nearer to the beam source and serves to determine the sense of any correction required. Once the beam position and focus are adjusted, the currents through the focusing coil 19 and deflecting coil 42 are locked at their respective magnitudes and the scanning is stopped for the duration of the welding cycle. In an alternative arrangement, Fig. 4 (not shown), the adjustments of focus and position are made manually whilst the outputs from the sensors are displayed on oscilloscopes. The sensors are preferably Faraday cages, but may be photovoltaic devices or thermistors. The system can also be applied to particle accelerators or to ion beam tubes used for ion deposition.
