Title: Voltage stress-resistant conductive articles
IPC: H01C7/02
Filed: 1973-12-21
Abstract: 1456047 PTC resistor devices RAYCHEM CORP 21 Dec 1973 [29 Dec 1972] 59637/73 Heading H1K [Also in Division H5] Resistive heating elements which are selfregulating because of their positive temperature coefficient of resistance and which comprise carbon black dispersed in a crystalline polymeric matrix are stabilized against resistance variation resulting from prolonged use at high voltages, e.g. 220 V, by providing at least 1À5 times the amount of carbon black at the electrode surfaces compared with that elsewhere between the electrodes. The electrodes, e.g. of copper, tinned copper, nickel-plated or silver plated copper, are first coated with a high content, e.g. 30 to 75%, carbon black containing composition, then the lower content composition is extruded around and between the coated electrodes. The electrodes are preferably elongate so as to provide a dumb-bell shaped element. The assembly is annealed, jacketed and subjected to ionizing radiation to cross-link the matrix polymer without reducing its crystallinity below 20%, so that it has a non-linear temperature coefficient of thermal expansion. The matrix polymer is selected according to the desired self-limiting temperature, and may be polyethylene, polypropylene, polybutene - 1, polydodecamethylene pyromellitimide, ethylene propylene copolymers and terpolymers with non-conjugated dienes, polyvinylidene fluoride or vinylidene fluoride tetrafluoroethylene copolymers, or polymer blends such as polyethylene and ethylene-ethyl acetate copolymer, or blends containing wax. Fillers such as silica may be included. Further improvement is achieved by so forming the resistive composition that at least at the electrode surfaces, it comprises polar polymeric material selected from polymers containing carboxylic acid groups and having an acid number of at least 3, ammonium, alkali metal, alkaline earth metal or zinc salts of such polymers and polymeric amines of amine number greater than 3. Such compositions form the subject of Specification 1,456,048.

Abstract: 1,271,300. Measurement of radioactivity. COMMISSARIAT A L'ENERGIE ATOMIQUE. Dec.31, 1969 [Jan.14, 1969], No.63438/69. Heading G1A. The amount of an element having high alpha activity diluted in a substance having low alpha activity, e.g. plutonium 239 and 240 in a uraniumplutonium alloy, is determined by measurement of the area of the degraded α-particle emission spectrum of a sample of the alloy between two predetermined energy limits and correction of this measurement to allow for background and other low activity α-emissions. Fig. 3 shows the degraded α-particle emission spectrum for the alloy. The low energy part A is affected by background noise and is not usable. The higher energy part C, including the peak S 1  caused by the plutonium isotopes of interest, is also rendered unusable by fine spectral lines from interfering oxidation and contaminating elements. Thus only the section B is used for measurement purposes. The measurement is subsequently corrected to allow for the contributions to the spectrum of Pu 238 and Am 241 which have a low α-activity and produce peak S 2  (and continued dotted curve). Also the measurement is corrected for the contribution of uranium isotopes. The apparatus suitable for carrying out the measurement is a vacuum enclosure with a sample holder turn-table 7. Radiation from a sample 6 reaches a silicon junction or surface barrier diode 2 via a collimater 5 and a cylinder 10 packed with anti-scattering material. A high energy α-emitter such as a Curium 244 or Californium 256 is used at 3 and acts as a reference energy (S 3  in Fig. 3) against which variations in gain of the detector circuit and zero drift in the analyser are compensated for. The apparatus is calibrated with known samples.

Abstract: 672,817. Refining asphalt. BARBER OIL CORPORATION. Nov. 30, 1949, No. 30746/49. Class 22 A solution of asphalt in a solvent is mixed with water, the amount of solvent being greater than the water and the specific gravity of the solvent phase differing from the aqueous phase, and mineral matter above 10 microns is separated by gravity from the asphalt solution which still contains substantially all its original spirits, a heating oil, benzol, solvent clay. Specified solvents are mineral naptha, dipentine refined turpentine, monochlorpentane, carbon tetrachloride or carbon disulphide and are used in amount between 50 to 200 per cent by weight of the asphalt. Heat may be used to aid solvation and the apparatus used may be a closed one, and under pressure. Water additional to that contained in the crude asphalt may be added and it may contain a salt, e.g. sodium chloride or sulphate or calcium chloride. The water added is such as to give a total of 2 to 20 per cent by weight of the asphalt. Separation of the two liquid phases may be by decanting or centrifuging and the solvent may be recovered from the asphalt solution. Continuous operation may be attained by the use of two containers, used alternately for dissolving and separation of the two phases. To aid solution the asphalt may be ground. The method may be applied to asphalt which has been partially refined by removal of its contained water.
