Title: Deep penetration welding using coherent optical radiation
IPC: B23K26/14
Filed: 1972-02-28
Abstract: 1336806 Welding by fusion UNITED AIRCRAFT CORP 28 Feb 1972 [8 March 1971] 9129/72 Heading B3R [Also in Division H1] In order to effect deep penetration welding using a continuous wave beam of coherent optical radiation (e.g. a laser beam), workpiece surface reflectivity is reduced, and hence absorption is increased, by increasing surface temperature by setting the power density and power of the beam such that material at the point of beam impingement is vaporized faster than the heat is diffused from said point. By such arrangement, a void is formed, and to avoid creation of a hole the beam is removed or increased in travel speed prior to the expulsion of substantial material from the void. The step of beam removal consists of moving the beam relative to the workpiece so that the void translates through the material, solidification and welding occurring behind the beam. The beam is preferably moved relative to the workpiece at a speed of at least 10 focused spot diameters in the time required for hole creation. The beam is preferably one working in the TEM 00  mode with an output of at least 3 kW. and with the beam focused to provide a power density between 10<SP>6</SP> and 10<SP>8</SP> watts/inch.<SP>2</SP>. Beam focal distance/aperture is preferably greater than 4. It may be necessary to increase beam power to initiate vaporization, and then to reduce power to prevent hole formation. Surface absorption may be increased artificially by a coating highly absorbent at the laser wavelength. The method of the invention may be applied to both butt and lap welds.  As shown, a laser 10, such as a CO 2  laser at 10À6 microns wavelength, generates a TEM 00  beam 12 which is focused by a mirror 14 on to a workpiece 16 (e.g. two metallic pieces to be seam welded). The workpiece is mounted on a motor-movable table 18. Inert gas 22 may be supplied to prevent undesirable surface reactions. The mirror 14 may be of any suitable geometrical shape, e.g. spherical, elliptical, parabolic. Spherical aberration due to off-axis focusing with a spherical mirror may be minimized by restriction to less than 10 degrees off-axis angle or by using two mirrors curved and located so as to cancel aberration. Transmitting optics may replace the reflecting optics shown.

Abstract: <PICT:0717784/III/1> <PICT:0717784/III/2> Emulsions are homogenized by forcing at a pressure not less than three atmospheres into one or more rotation chambers so as to produce a liquid vortex, the homogenized emulsion leaving through an axially arranged discharge aperture.  As shown in Fig. 2A, liquid is introduced from pipe 11 through a tangential inlet into chamber 21, two oppositely directed liquid vortices being produced and the liquid leaving through conical apertures 19, 20 which convert part of the kinetic energy into static pressure, as described in Specification 693,649, [Group II]. Apparatus is also described Fig. 1 (not shown), in which only one outlet is provided.  In Fig. 3A, liquid passes in parallel through a series of rotation chambers arranged in two concentric circles between flanges 31, 32; liquid enters through passage 35 and leaves through conduits 43, 48.  A second homogenizing device may be provided in series, working at a lower pressure and having larger rotation chambers.  The emulsion to be homogenized may be formed in the apparatus described in Specification 708,355.

Abstract: 1,064,624. Data transmission. GENERAL DYNAMICS CORPORATION. March 4, 1965 [March 9, 1964], No. 9348/65. Heading H4P. [Also in Division G1] To reduce the probability of error in a data transmission system in which each bit is transmitted by phase shift keying of a carrier and is accompanied by a reference frequency close to the carrier, the receiver includes means for broadening the frequency spectra of the signals and feeding the resultant signals to a correlator to derive the original data. At the transmitter n bit parallel data phase modulates n different carriers which are harmonically related to the character rate. The modulated signals are added, together with n reference frequencies which are the harmonics of the character rate adjacent said carriers. After transmission over a radio path the modulated carriers and the reference frequencies are separated by filters, and the reference frequencies are converted to the same frequencies as the corresponding carriers. The signals feed filters which broaden their frequency spectrum and lead to correlators. The resultant signal is sampled for regeneration of the n-bit parallel signal.

Title: Improvements in or relating to high frequency electrical power measuring apparatus
IPC: G01R21/00
Filed: 1950-04-19
Abstract: 678,836. High-frequency power measurements; bridge circuits. GENERAL ELECTRIC CO., Ltd., and FLINT, F. C. April 19, 1951 [April 19, 1950], No. 9619/50. Class 37. A high-frequency power measuring apparatus comprises a resistance bridge 1 having in one arm a bolometer or other temperature-sensitive resistance 3, which is also connected in the highfrequency circuit the power in which is to be measured. The diagonal 5, 11 is supplied with D.C. from a full-wave rectifier 10 through a milliammeter 8 and resistances 6, 7. Across the same diagonal is a resistance 13 in series with a D.C. milliammeter 14 and a part of a potentiometer 15, which is connected across a half-wave metal rectifier 17. The bridge 1 is supplied between the corners 21 with lowfrequency A.C. from a valve oscillator 20,. balance being detected by an amplifier 23 and D.C. microammeter 24 connected across the diagonal 5, 11. Without applying any highfrequency power to the bolometer 3 the bridge is balanced by adjustment of the output of the oscillator 20, the D.C. through the milliammeter 8 being adjusted to a predetermined value. The bridge balances when the power dissipated in the bolometer 3 by both the A.C. from the oscillator 20 and the D.C. from the rectifier 10 raises its temperature to the point where its resistance is equal to that of the resistor 4, the arms 2 being equal. The highfrequency power to be measured is then applied to the bolometer, raising its resistance and unbalancing the bridge. The bridge is again balanced by reducing the D.C. flowing in the bridge by adjusting the potentiometer 15 so as to increase the D.C. shunted through the resistance 13. The D.C. through the bridge is reduced by this amount and the resistance of the bolometer 3 is lowered until the bridge is again in balance. The reading of the milliammeter 14 is a measure of the high-frequency power and may be calibrated to read power directly. Alternatively the amplifier 23 may actuate a servo-mechanism to drive the variable tap of the potentiometer 15 until the bridge is balanced. In a further form of self-balancing bridge the resistor 13 is replaced by a valve, the potential on the control grid of which is controlled by the output of the amplifier 23. The valve then passes a current dependent on the degree of unbalance of the bridge. Reference has been directed by the Comptroller to Specification 592,119.

Abstract: 586,317. Wave guides. COLLARD,J., and HILL, S. May 18, 1944, No. 9623. [Class 40 (v)] A wave guide, of the kind in which a longitudinal component of current flows only along certain portions of the surface of the guide and not along other portions of the surface, is provided with a coupling comprising a pair of flanges connected to the ends of adjacent sections, the flanges being in electrical contact with each other adjacent the portions of the guide where no longitudinal component of current flows and are arranged to be out of contact with each other adjacent the portions of the guide where a longitudinal flow of current occurs, the width of the flanges where they are spaced apart being such as to afford an effective short-circuit at the inner edges of said flanges. Figs. 1 and 3 show two sections 6, 7 of a rectangular wave guide having soldered to their ends coupling flanges 8, 9 which are bolted together so as to be in contact at raised bosses 10, 11 situated adjacent the shorter sides of the rectangular guide where no longitudinal current flows. The longer edges of the flanges are spaced apart slightly and have a depth of onequarter wavelength so as to present a shortcircuit at the inner edges where longitudinal currents flow. Alternatively, one coupling flange may be flat, the bosses being only on the other coupling, or both flanges may be flat, separation being effected by separate interposed conducting spacing elements. The side flanges may extend beyond the ends of the shorter sides of the guide.
