Title: Metal arc welding, composition, and method of making same
IPC: B23K35/362
Filed: 1959-11-19
Abstract: A particulate flux for use in submerged arc-welding particularly of rusty or heavily-scaled steel consists of a dispersion of microscopically fine metal globules in a metal oxide matrix.  Metals which may be present are Fe, Mn, Si, Cr, Mo, Ni and Co, and the matrix may also contain in addition to the oxides thereof oxides of Al, Ba, Ca, Sr, Ti, Zr.  The flux may be produced by melting the appropriate oxides, e.g. in an arc furnace, in the presence of a reducing agent, followed by rapid cooling of the product.  The preferred range of particle size is 0.04 mm. to 4.76 mm., with the metal globules in the range 2.5 microns to 250 microns.  A fluoride such as fluorspar may also be present in the composition; the latter may be used to add alloying elements to the weld metal.

Title: Improvements in photometric method and apparatus
IPC: G01J3/08
Filed: 1965-09-20
Abstract: 1,126,841. Photometry. KOLLMORGEN CORP. Sept.20, 1965 [Sept. 25, 1964], No.40009/65. Heading G1A. The reflectance or transmittance of a sample having a low value of their characteristics, relative to a reference is determined photoelectrically using high intensity light pulses of short duration synchronized to the passage of the sample upon a carrier past a testing location. In the arrangement of Fig. 1B apples are tested for ripeness according to their chlorophyl or water content. Two pulses of light are passed through each apple as of travels on a carrier 60T, past a detector 65A which receives transmitted light alternately at two wavelengths by means of the rotating filters A and B, which may also be positioned as dotted. One of the wavelengths #a is strongly absorbed by the substance indicating ripeness and the other #b is not and acts as a reference wavelength. The signals from the detector 65A corresponding to the two wavelengths are compared to give a difference signal e o  which by controlling the sensitivity of the detector in accordance with the reference wavelength signal gives the difference as a proportion of the reference signal. The gating of the two wavelength signals to the difference evaluator, the gating of the reference signal to the sensitivity control and the triggering of the light source are synchronised with the filter rotation by a commutator 96 receiving energizing pulses via switch 94 which are synchronized with the carrier drive. Alternatively a single pulse of light may be transmitted through the apple and a dichroic mirror arranged to reflect one wavelength on to one detector but transmit the second wavelength on to another detector Fig. 1A (not shown). Fig. 2 shows an arrangement for comparing the intensity of newspaper printing with plain unprinted areas. The pulses of light being timed to correspond with the printed and intermediate plain areas by means of pick-up coils 116 sensing magnets 117 mounted upon the printing roller or alternatively by a photo-cell scanning registration marks upon the newspaper. The associated circuitry is similar to that shown in Fig. 3 except that detector signals are integrated before comparison to give a differential signal which is recorded and used to control the supply of printing ink to the roller.
