Abstract: 1,228,898. Varistors. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 27 Sept., 1968, No. 46098/68. Heading H1K. A varistor composition comprises 5 to 9 parts by weight of SiC particles, 0À1 to 1 parts by weight of Cu and 1 to 5 parts by weight of ceramic binder. A varistor is produced by mixing the powdered constituents, pressing to shape, and sintering in a non-oxidizing atmosphere at a temperature above the melting point of copper. As shown, Fig. 2, the SiC particles 11 are held together by the ceramic matrix 12 which contains dispersed copper particles 13. The copper also diffuses into the SiC particles 11 to produce doped surface layers 14. The body may be in the form of a disc, square plate, bar, or cylinder and is provided with Zn electrodes by vacuum evaporation and leads are soldered to these electrodes. The body may be sintreed in N, A, He, or H which may contain a small proportion of oxygen. The SiC particles have a size of 30 to 200 Á and may contain A1, Fe and N as impurities. The binder may be clay, pottery stone, or a refractory oxide or a mixture of these and may also contain graphite powder having a particle size of 0À1 to 50 Á. The Cu may be provided in elemental form or as a compound, e.g. an oxide, hydroxide or carbonate and comprises particles having a size of 1 to 20 Á.

Abstract: 1,231,907. Measuring light reflected from a coloured surface. MILES LABORATORIES Inc. April 3, 1969 [April 22, 1968], No.17706/69. Heading G1A. An instrument for measuring light reflected from a coloured surface having a predetermined range of colour reflectance values comprises a light source, a reference circuit including means providing a reference reflectance surface and a photo-electric cell exposed to light from the source reflected from the reference surface and which is connected to adjustably control the current flow to and thereby the light emitted by the source in a manner to maintain constant emission, means for supporting a member having a surface to be investigated in a position in which the surface is exposed to the source, a measuring circuit including a photo-cell exposed to light reflected from the surface, an indicating meter, and a power source for the light source and the reference and measuring circuits. The sample which may be a bibulous carrier impregnated with reagent is located in an aperture 34, Fig.2, by a block 56 on the casing lid and light from a lamp 136 is reflected by the sample on to photo-cells 128, 132, and by a reference surface 126 on to a reference cell 130, the lamp and the two reflecting surfaces forming an isosceles right angled triangle. The measuring cell outputs are amplified, and indicated by a moving coil meter 75 and a range change switch 92 besides selecting appropriate resistors in the meter circuit turns an appropriate scale to the front of the instrument. The pivot point of the moving coil meter is set to one end of the scale and the resulting non-linear indication on the scale is said to compensate for non-linearities in reflectance. The apparatus is switched on by a block 54 engaging the push buttons of a switch 160 when the lid is closed and the battery power source is automatically checked when the lid is roused with the range change switch in a check position. A meter short circuiting arrangement is provided to dampen needle movement during transport and separate regulators are provided for the supply to the lamp and the photo-cells. A jack may be fitted for charging the battery. Examinations of a strip for a blood glucose test is exemplified.
