Abstract: 479,523. Inductance and capacitance measurements. GENERAL ELECTRIC CO., Ltd., TURNER, H. C., and NUTTALL, T. C. July 6, 1936, No. 18708. [Class 37] Apparatus for measuring the thickness of metal foil forming an element of the electric coupling between an oscillation transmitter and receiver, includes a symmetrical compensation circuit associated with a calibrated vane, the symmetrical receiver circuits being connected to oppositely directed bridge rectifiers, the out-of-balance continuous-current from which is applied to a galvanometer G. Symmetry between the transmitter and receiver circuits is obtained by relating the values of inductance, capacitance and effective shunt resistance as follows L1/L2=C2/C1=R1/R2. The amount of the out-of-balance current can be varied by an adjustable resistor R3. The resistors R1, R2, or condensers C1, C2 may be adjusted to correct the symmetrical relationship of the circuits.

Abstract: 1,184,643. Frequency synthesizers. C.I.T.- COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. 17 Oct., 1968 [30 Oct., 1967], No. 49338/68. Heading H3F. A frequency synthesizer has a range of frequency positions at each of which a unique frequency is delivered and is provided with a switching arrangement operable to select simultaneously any pair of frequencies spaced from one another by a constant number of frequency positions. It includes a lower order oscillator 1 selectively connectable, i.e. by means of AND gates 10-19, to a first set Qu of quartz crystals to provide a lower order frequency determined by the crystal to which the oscillator is connected, and two higher order oscillators 2, 3 selectively connectable, i.e. by AND gates 20-29 and 30-39 respectively, to respective positions in a second set of quartz crystals Qd to provide respective higher order frequencies determined by the two selected crystals which are always spaced from one another by a constant number of crystal positions in the second set. First and second modulators 4, 5 respectively receive the higher order frequencies from the oscillators 2, 3 and both receive the lower order frequency from oscillator 1, to provide respective output frequencies f R  and f E  spaced apart by a constant amount in the range of frequency positions. A logic circuit 60, 61, 62 controls the selection of the quartz crystals determining the output frequencies of the three oscillators in accordance with a logic input signal significant of the output frequency pair to be delivered. The desired pairs of output frequencies are obtained by coupling the logic signal inputs of AND gates 20-24 to those of AND gates 35-39 respectively and of AND gates 25-29 to those of AND gates 30-34 respectively The mixers 4, 5 add the frequencies from oscillator 1 and from oscillators 2, 3 respectively. The controlling logic circuit comprises a clock pulse generator 60 delivering pulses to a counter 61 which operates a decoder 62. The arrangement is more particularly intended for use in a transmitter/receiver station for duplex operation, in which a pair of constantly spaced frequencies is required for transmission and reception respectively.

X-ray apparatus comprises a fluorescent screen for converting an X-ray image into an optical image and a light source arranged to illuminate said optical image with light of a colour different from the colour of the optical image whereby contrasts in the image are converted to differences in colour. An X-ray source 10 illuminates an object 30 the transmitted image being rendered optically visible at 40 by a fluorescent screen 20. The surface 21 of the screen is illuminated by coloured light 60 reflected by a partially transparent mirror 70 from its source which comprises a coloured filter 55 with associated lens system 53, 54 and incandescent bulb 52. The combined light of the optical image 40 and the coloured light reflected from the screen 21 is viewed by an observer at 80 who sees a multi-coloured image according to the ratio of the intensities of the components of the combined light. The colour and intensity of the illuminating light 60 may be altered by varying the voltage of power source 51 or by changing the filter 55 for an alternative 551. It is preferred that these filters produce a light, 60, that is red, blue or green, i.e. the primary colours, and the colour of the optical image 40 may be similarly selected.

Abstract: 1487227 Photoconductive coatings PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 Nov 1974 [29 Nov 1973] 51132/74 Heading B2E [Also in Divisions G2 and H1] A method of manufacturing a photosensitive material comprising a non-conductive hydrophobic substrate bearing a photosensitive semiconducting metal oxide having a light-reaction product capable of separating copper and/or Hg, Ag, Au, Pt or Pd from a solution of the relevant metal salt, comprises the step of contacting the substrate with a dispersion of particles of the photosensitive semiconducting metal oxide in a dispersion medium, said particles having a charge sign opposite to the charge sign of the substrate material on the surface in the dispersion medium, the excess photosensitive semiconducting metal oxide particles which are only loosely adherent to the substrate material being subsequently removed by rinsing and the product thus obtained being heated to a temperature of more than 50C but less than the softening point or the decomposition point of the substrate material for a period sufficient at that temperature to bond the particles to the substrate material, A photosensitive coating having a thickness of one grain is provided. Suitable charge conditions can be achieved by controlling the pH of the dispersion. The material may be used as starting material for the manufacture of printed circuit boards. The particles may be catalysts for electroless deposition of metal coatings; alternatively the photo-sensitive semiconducting compound after contacting with a solution of a noble metal salt and exposure to light produces noble metal nuclei that can be plated. In one embodiment glass-fibre reinforced epoxy board material with a monograin layer of TiO 2  of particle size less than 0.5mm provided by a dispersion of pH between 1 and 6 is used and after drilling of holes a similar TiO 2  dispersion is applied in the holes. A dispersion of ZnO particles can also be used. After rinsing and drying in air at 80C an nuclei-forming soln. containing PdCl 2  is applied. Following imagewise exposure palladium ions are removed from non- exposed areas by rinsing and the image is then intensified with a soln. containing copper sulphate, EDTA and ultrasodium salt, NaOH and formaldehyde to form an adhering pattern. Plates of glass, yttrium-gadolinium-iron garnet, Al 2 O 3  and a ceramic composed of TiO 3 , BaO and ZrO 3  are other specified substrates.
