Title: Improvements in or relating to electric heating cables
Inventor: REYNOLDS EDWARD HENRY
IPC: H05B3/14
Filed: 1961-08-10
Abstract: A ceramic semi-conducting powder is produced by introducing into the crystal lattice of barium titanate or barium strontium titanate 0.1 to 3% of a substitutional impurity: lanthanum, bismuth, cerium, or thorium may be introduced into barium or strontium lattice sites, and vanadium, tungsten, niobium, antimony, or tantalum into the titanium lattice site.  Magnesium, chromium, or zirconium oxide may also be incorporated in the material. Examples of numerical composition are given. In a typical method of preparation, oxides of Mg, Cr or Zr are milled with TiO2 and barium and strontium carbonates, the mixture calcined at 1100 DEG  C., crushed, pressed and air fired first at 1350-1400 DEG  C. and then at 1200-1250 DEG  C. The titanate is then water quenched and ground, after which it may be moulded and its resistivity adjusted by heating at 800 DEG  C. in hydrogen.

Abstract: 833,590. Glass forming. BRITISH THOMSON-HOUSTON CO. Ltd. Sept. 2, 1958 [Sept. 16, 1957], No. 29110/57. Class 56. In the manufacture of a stemmed hollow article from glass from a part-formed article comprising a bowl having a base united therewith through a neck of constricted crosssection and of length less than that required for the final stem and in which the bowl and base are substantially set but the thicker neck is still workable, the bowl and base are moved apart to elongate the neck to form the stem. As shown in Fig. 1, the part formed article G, which may be formed as disclosed in Specification 822,585, has bowl I and base II joined by a thick neck III, the bowl I being supported by a yoke 11, comprising a pair of jaws 11<SP>1</SP> which engage a groove 10, carried by support rods 14 depending from a ring 15 rotatably supported by a fixed plate 16 and the base II being gripped by a clamping ring 17 in two parts 171 each having a groove 18 to engage over the edge of the base II to clamp it to a platform 19 carried by a vertically movable rod 22. The jaws 11<SP>1</SP> and engaging parts 20, 21 of the lower clamping ring 17 are of heat insulating material. Before closing the ring 17, the neck III is reheated as by burners 29 and the neck elongated by operation of hand lever 50 to lower the platform 19, the positions of the platform being limited by stop collars 28 and 30 engaging fixed plate 25 and bushing 24 on fixed plate 26, a spring 27 normally urging the platform to its upper position. The article is held in the lowered position until the elongated neck is set and the article completed by burning off just below the groove 10. In an alternative, the top burning off of the article is done first and the lower part of the bowl I supported in the yoke 11. As shown in Fig. 4, the base II of the inverted article G, with its top already burned off, is supported on a neck yoke 31 and a bowl grip 34 has jaws 34<SP>1</SP> to be closed over the bowl I and lowered to elongate the neck III. Each jaw 34<SP>1</SP> is mounted on an arm 38 pivoted at 46 to a lug 41 on a member 39 secured to a hollow rod 42 and at its end to a link 45 pivoted to one side of an actuating member 40 at the head of a rod 44 sliding within rod 42. Downward movement of rod 44 as by a lever 50 or by automatic mechanism, moves the jaws 34<SP>1</SP> inwardly to grip the bowl I, further movement of rod 44 then moving rod 42 downwardly to elongate neck III, the rods being returned by springs 47, 48 and upward movement being limited by a stop collar 49.

Abstract: 1511236 Copying by scanning CROSFIELD ELECTRONICS Ltd 26 June 1975 [1 July 1974] 29113/74 Addition to 1374521 Heading H4F Defects in an original which is to be copied by scanning are rendered less evident in the copy by generating a signal related to an area of the original that includes the defect and, when the defect is scanned, substituting this signal for the image signal provided by the scanner. The arrangement is substantially similar to that described in Specification No. 1,374,521, but instead of using a retouching mask, i.e. an intermediate copy on which the defects are marked, e.g. by painting, it is the defects on the original that are so marked. The marks on the original are made in, for example, fluorescent or infra-red absorbent paint. The scanner provides a defect signal which is distinguishable and separable from the normal image signal when a mark is detected, e.g. the defect signal may have a significantly different amplitude or be generated by an additional sensor which is sensitive only to the marks. To prevent the appearance on the copy of an outline fringe around the defect area the signal substituted for the defect may also replace portions of the image signal which are adjacent the defective portion. The substitution signal is a function of the density of portions of the original adjacent the defect and possibly also of the defect itself.
