An electrically conducting silver image is produced by imagewise exposing a photographic water-permeable macromolecular colloid-silver halide material to form a latent developable image, and then forming, by silver complex transfer development, in the unexposed areas of the outer colloid layer of the material, a conductive silver surface image having a resistivity of not more than 5 ohms per square and less than 0À01 times that of the exposed areas. Conventional emulsions with the usual additives may be used and the material may carry an outer non-sensitive water-permeable colloid coating e.g. gelatine, which may contain SiO 2 . The development may be carried out in a single bath containing a highenergy developing agent, e.g. p-amino phenols, hydro quinones, 3-pyrazolidones, or mixtures thereof, a silver halide solvent e.g. a thiosulphate or thiocyanate; and a nucleating agent e.g. K 2 S, Na 2 S, BaS, H 2  S, K 2 Se, Na 2 Se, K 2  CNS, Na 2  CNS or thourea. Thiocyanates may act as both solvent and nucleating agent. Alternatively the development may be a two-bath process with the high energy developing agent in at least the second bath, and the solvent and nucleating agent in the second bath. The material may be washed before development. The conductive material may form a printed circuit.

Title: Method and arrangement for ultrasonic contactless measurement of thickness of objects
Inventor: CHEBYSHEV ANATOLY DMITRIEVICH
IPC: G01B17/02
Filed: 1967-09-13
Abstract: 1,147,417. Ultrasonic testing. UKRNIIPLASTMASH. 13 Sept., 1967, No. 41721/64. Heading H4D. The Specification describes an arrangement for determining the thickness of an object, e.g. the walls of tube 2, using ultrasonic waves. The output of a high frequency oscillator 8 is frequency modulated according to a triangular characteristic by means of variable duration triangular pulse generator 6 and frequency modulator 7. After amplification at 9, the frequency modulated signal is transmitted, as an ultrasonic beam by transducer 1, towards the tube wall. Reflections occur at both the outer and the inner wall, which reflections beat in receiving transducer 5 to produce a high frequency sum frequency signal amplitude modulated by a low frequency differency frequency signal. The frequency of the amplitude modulation, appearing at the output of detector 11 is characteristic of the path difference for the two reflections, i.e. the wall thickness. The duration of the triangular pulse output of generator 6 (i.e. frequency sweep) is controlled in dependence on said thickness so that said difference frequency remains constant at a predetermined value. Thus the output of detector 11 is fed to two tuned amplifiers 12 having different centre frequencies such that said predetermined frequency is within the passbands of both and output signals of equal amplitude are produced by the two amplifiers as a result of the application of a signal at said predetermined frequency to the paralleled inputs thereof. The outputs of the amplifier are fed to the inputs of a frequency discriminator 14 which thus gives a signal, representing by sign and magnitude, the deviations of the difference frequency from said predetermined frequency, and thus constituting a control signal for generator 6. The duration of the pulse output of the generator 6 thus represents the thickness and is shown on recorder 16. Automatic gain control means 18 is provided.

For sealing a piston in a cylinder so that leakage past the piston is practically the same on the forward or return stroke, either the cylinder, Fig. 2, or the piston, Fig. 3, has a sheath-like flexible metal element 24 or 39 which is coaxial with and connected to a similar element 26 or 35 with an annular gap 27 or 40 between them, the element 26 or 35 being connected at a position nearest, and in the direction of the free end of, element 24 or 39 to a portion 21 or 33 of the cylinder or piston and each element having a length equal to at least four times its radial thickness. The elements may be cast integrally with each other and with the cylinder or piston or they may have a soldered, welded, riveted or shrink connection. In Fig. 2 the elements 24, 26 are each connected integrally with an annular element 25. In Fig. 3 the portion 33 and the element 35 are connected to supports 36 equally spaced around a portion 31 of the piston which is soldered to the portion 33. In a modification, the sheath-like elements on a hollow piston having a piston rod integral with its head portion are each connected to an annular element in the manner shown in Fig. 2. In operation, depending on the stroke, the motive fluid enters either the gap 27 or 40, or the annular passage 22 in the cylinder or the interior of the piston and slightly deforms the elements radially to maintain a narrow gap between the piston and the cylinder wall.

Title: Improvements in the production of chlorinated isocyanuric acid
Inventor: MARKEL KARL
Filed: 1959-12-15
Abstract: Chlorinated isocyanuric acid is produced by leading Cl2 into an aqueous solution of sodium or potassium cyanurate until the pH is less than 7, adding an alkali compound, i.e. sodium or potassium hydroxide, carbonate, or bicarbonate, preferably in aqueous solution, in amount equivalent at most to 30% of the free and combined cyanuric acid, and continuing addition of Cl2 until the pH is 5 to 2.5.5-20% solutions of di- Na or K cyanurate or tri- Na or K cyanurate produce pure di- or tri-chloroisocyanuric acid respectively.  A mixture of di- and tri-chloroisocyanuric acids may also be prepared.  The reaction may be effected at normal or elevated pressure at temperatures below 100 DEG C., preferably below 50 DEG C. for di-chloro-acid and below 40 DEG C. for tri-chloro-acid, particularly -10 DEG  to 35 DEG C.  The reaction may be in the presence of water-miscible liquids, e.g. methanol, ethanol, acetone, acrylonitrile, aliphatic or aromatic amines, phenols, urea, or formaldehyde.  Addition of the alkali compound may be all at once, periodically, or continuously, and the further addition of Cl2 may be during and/or after the alkali compound.  The solid crystalline chlorinated isocyanuric acid may be separated from the reaction mixture mechanically, and washed with water, and the mother liquor and washings may be reused in the process.  The acid may be dried below 100 DEG C. preferably at below 50 mm. Hg. pressure. Alternatively, the acid may be dried by treating with water-immiscible organic liquids, e.g. benzene or carbon tetrachloride, preferably at below 50 DEG C. in vacuo.  Decomposition of the acids or their salts may be inhibited by adding formaldehyde, or salts of phosphorus acid or of hydroxylamines.
