Title: Manufacture of composite welding electrodes
IPC: B23K35/30
Filed: 1971-09-10
Abstract: 1369843 Making welding electrodes; drawing; welding by fusion PYROTENAX Ltd 8 Sept 1972 [10 Sept 1971] 42380/71 Headings B3A B3P and B3R In a method of making a composite metal sheathed welding electrode, which is comprised of a tube 2 of metal or metal alloy containing a material or mixture of materials consisting of or including a deoxidizing agent or flux in granular or powder form, compaction of the powder or granules is effected in the tube and the diameter of the tube is reduced further to compact the powder or granules and to reduce the filled tube to its required size. A guide tube 7 is adjustably supported in a feed funnel (11), Fig. 4 (not shown), and is a sliding fit in a copper sheath tube 8. The tube 7 is closed at one end by a guide 13 having passages through which a powdered mixture 1 of aluminium and flux can pass. The tube 8 is drawn through a die 9 by a chuck 16 to form the sheath 2 and at the same time is vibrated by hammers 20, 21. The mixture 1 is continuously fed into the funnel (11) at a rate which maintains the sheath full, without "push-back" of the powder. The filled sheath is withdrawn from the apparatus and drawn down to final size in a series of dies. Before the final reduction a second tube of a metal or alloy different from that of the first tube may be placed over the filled tube and the tubes are drawn to size together. For welding aluminium bronze, the sheath comprises a copper tube, or an inner tube of aluminium and an outer tube of copper, and the core comprises powdered aluminium and a flux. Alternatively a mild steel or alloy steel sheath encloses a powdered mixture of tungsten carbide and silicon manganese and may have a nickel wire embedded in the core to act as an alloying agent. The core may include slag-forming additives, e.g. rutile, calcium fluoride, limestone, alkaline earth carbonates and alkaline earth oxides, and alloying additives may also be included, e.g. pure metal, metal carbides, metal borides and intermetallic compounds. In alternative methods, the powder may be compacted by tamping and the final reduction may be performed by rolling. If the electrode stock is to be coiled, the final drawing or rolling is accompanied by intermediate annealing.

Title: Improvements in and relating to devices for stereophonic reproduction of signals
IPC: H03D1/22
Filed: 1964-10-26
Abstract: 1,027,539. Stereophonic radio receivers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Oct. 26, 1964 [Oct. 29, 1963], No. 43521/64. Heading H4L. A receiver for stereophonic radio signals of the type described in Specification 1,022,769 in which the presence of a pilot signal automatically switches the receiver for stereophonic reproduction, is provided with means for preventing this switching operation by interfering signals in the proximity of the pilot signal frequency. The receiver includes conventional frequency - changer, I.F. and discriminator stages, the composite signal at the output of the discriminator 8 being supplied via a filter 27 to a switched type stereo decoder 35. The 19 kc/s. pilot signal is selected by a filter 16, amplified at 17 and supplied to a frequency-doubler 20 of the full-wave rectifier type. A bi-stable trigger 24 is arranged so that in the absence of a pilot signal transistor 46 is cut-off due to positive bias applied to its base via resistor 54, and transistor 45 is conducting. The 38 kc/s. switching signal from the frequency-doubler is supplied to the base of transistor 46, the D.C. component being blocked by capacitor 48, and the D.C. component of the switching signal is supplied to the base of transistor 45 via resistor 47. When a monaural signal is present any interfering signals appearing in the pilot frequency channel 15 are blocked by the non-conductive transistor 46 and the monaural signal is supplied via the switching circuit 35 to the output stages 41, 42 in parallel in conventional manner. On reception of a stereophonic signal the D.C. component from frequency-doubler 20 causes transistor 45 to be cut-off when the pilot signal exceeds threshold value, after a delay determined by the charging time of capacitor 48, and the 38 kc/s. switching signal is supplied via transistor 46 to the stereo decoder 35 supplying the A and B signals via respective transistors 41, 42 to the reproducers 39, 40. An adjustable resistor 147 compensates for cross-talk. A meter 53 in the emitter circuit of transistor 46 provides an indication of stereo reception.

Filed: 1968-09-16
Abstract: 1,221,703. Measuring bridge circuits. DALE ELECTRONICS Inc. Sept. 16, 1968, No. 43975/68. Heading G1U. An apparatus for testing the resistance v. time or temperature characteristics of a resistance element having a given power rating and capable of receiving a maximum safe overload power greater than the power rating incorporates a resistance bridge arrangement 12 to which the test resistance element 10 is connected, a power circuit 18 for the bridge for delivering power to the element in excess of the power rating and less than the maximum safe overload power and a timing device 14 in the power circuit for selectively closing the circuit for a predetermined interval. The power ratings of the bridge components are substantially greater than the power delivered to them by the power circuit. A measuring system 20 is connected to the bridge output to determine the change in resistance of the test resistor during the time interval. It is stated in the Specification that for a good resistor, the change in resistance with the applied high wattage will increase linearly at less than a certain rate, while for a poor resistor, the variation of the resistance with time will be irregular. These variations may be observed on an oscilloscope or pen recorder 20. The temperature of the resistor may be detected by a suitable sensor and the variation of resistance with temperature instead of time may be recorded. From this may be determined the temperature coefficient of resistance, which again should be below a given amount.

Abstract: 1371374 Television EASTMAN KODAK CO 23 Sept 1971 [25 Sept 1970] 44345/71 Heading H4F A record medium 18 carrying two or more superimposed monochrome images modulated with respective regular diffraction grating patterns, i.e. differing in orientation and/or frequency, is scanned by light passed by an aperture 17 and lens 14 from a flying spot scanner 10, a further lens serving to provide at least one spatially separate stationary diffracted image 31, 33 of the aperture 17 for each image on medium 18, which diffracted image varies in intensity as the medium is scanned and may be detected by a respective photo-electric pick-up 36 to provide a corresponding video signal. All the diffracted images may be passed to a single plane 28, 38 at which is located either an array of pick-ups 36, Figs. 4 and 5 (not shown), or a correspondingly apertured plate with optic fibres connecting the aperture to respective detectors, Fig. 3 (not shown). In the latter alternative, it is said that the apertured plate is not strictly necessary. Alternatively the light from lens 26 may be divided by an arrangement of half mirrors into as many beams as there are images recorded on medium 18, Fig. 2 (not shown), the diffracted images corresponding to a different one of the recorded images being selected and detected in each beam, e.g. using a detector array or apertured plate as outlined above. As particularly described, either one, or both, first order images, or a plurality of different order images may be selectively detected for each image recorded at 18. The aperture 17 may be, e.g. oval, square or triangular, and may consist of an array of apertures. The grating pattern may be of  parallel strips alternating in transmissivity, reflectivity and/or optical path length (variable thickness or refractive index). For example transmission gratings are obtained by preexposing a photographic medium 18 comprising, e.g. red, green and blue sensitive layers, or a single layer having grains of different colour sensitivity, to corresponding coloured gratings. The system may be used for deriving three primary colour signals for colour television, the signals being used simultaneously or sequentially.
