Title: Device for the protection of insulators aganst electric arcs
IPC: H01B17/46
Filed: 1963-03-06
Abstract: 982,459. Insulators. COMPAGNIE GENEKALE D'ELECTRO-CERAMIQUE. March 6, 1963 [March 26, 1962], No. 8953/63. Heading H2C. A device for protecting insulators against electric arcs comprises arcing horns with C- shaped face ends 12 and 13 connected to a bracket 3 from which insulators 4 are suspended or secured. When flashover occurs the points at which the upper and lower arcs impinge upon the protective horns situated between the two insulators tend to move towards one another and to merge as a result of electromagnetic action into a single arc which is easier to blow out. In order not to reduce the surface leakage distance, the horns do not project over the ceramic of the insulating stems. As described, the arrangement is used for suspending a line 5 from a pylon 6 and four horns are used at each junction.

Title: Improvements in or relating to methods of forming p-n junctions in crystalline semi-conducting materials
IPC: H01L21/00
Filed: 1953-03-31
Abstract: 768,022. Semi-conductor devices. GENERAL ELECTRIC CO., Ltd., and JAMES, E. G. Sept. 30, 1953 [Oct. 15, 1952; March 31, 1953], Nos. 8975/53 and 8976/53. Divided out of 723,179. Class 37. P-N junctions are produced in crystalline semi-conducting material by producing, in an inert atmosphere or vacuum, on top of a solid semiconductor body of one conductivity type a molten layer of the semi-conductor material formed at least in part by melting the tip of the body, and then crystallizing the molten layer, which contains sufficient of at least one impurity of opposite conductiv, ity type to ensure that at least the first part of the layer to solidify is of opposite type to the main body. Preferably the original body is monocrystalline and the solidification progressively upward so that the resultant body is also monocrystalline. In one embodiment a monocrystalline slice of N-type Ge 24 is placed on graphite block 25 mounted for vertical movement on a cooled chamber 19 on rod 20 in a chamber 1 through which a current of argon flows, the slice being heated from above by a carbon heating element 7 mounted in watercooled blocks 8 and 9. A thin layer of powdered P-type Ge on top is melted together with a thin surface zone, the P-type impurity being sufficient to ensure that the whole molten mass solidifies from the bottom upwards as P-type Ge when the slice is lowered. The resulting single crystal may be cut into fragments and made into PN diodes or into PNP junction units by diffusion of impurities such as In into the N-type zone. In a second method after part of the molten layer has solidified lowering of the slice is interrupted and powdered N-type Ge added to the Ge remaining molten to give a further N- type layer. Alternatively powdered Ge made N-type by inclusion of As which is more soluble in liquid than in solid Ge, and Ge made P-type by inclusion of B which is more soluble in solid than in liquid Ge are both sprinkled on the body and melted together with the surface zone the relative quantities being such that the first thin layer to solidify is P-type while the remainder is N-type. In all cases blocks of material may replace the powder, or the whole of the molten Ge may be derived from the top of the body, the impurities being added directly to it. The added Ge may also be in liquid form produced by fusion of powdered material in falling through a heated coil on to the body, or melted in separate vessels and poured over the surface. A rod of Ge with axis vertical may replace the slice and after formation of junctions thereon the tip is removed and the process repeated.

Abstract: 732,731. Inking-apparatus. GOSS PRINTING PRESS CO. April 1, 1953 [Sept. 23, 1952], No. 9051/53. Class 100 (2). The transfer roller of an ink fountain has means for moving it between two positions according as the associated printing unit is being operated directly or in reverse, the transfer roller in the first position engaging one roller of the ink feed path, and in the second position engaging another oppositely rotating roller of the ink feed path. As shown, the transfer roller 33 of an ink fountain 30 serves as the driving means for the fountain: it frictionally drives a feed roller 32 coupled through worm gearing 37 to a slowly rotating fountain roller 31 dipping into a trough 34 and with a knife 35 locally adjusted along its length by keys 36. The roller 33 is applied to, and rotated anticlockwise by, an auxiliary drum 24 forming with other rollers and drums (not shown) the inking- system of a reversible rotary printing couple; when the couple is to be run in reverse, the roller 33 is applied to an ink roller 25 adjacent the drum 24. A path of movement as indicated at 98, 99, Fig. 3a, to give a substantially radial approach during adjustment of the contact pressure, is obtained by mounting each end of the front of the fountain on an eccentric cylinder 61, Figs. 3 and 11, supported on a bolt 73 mounted in brackets 70 welded to the front wall 53 of a fixed trough-shaped base-plate 50; each cylinder 61 is externally toothed to engage a worm 76, Fig. 3, manually rotated by the square head 80 of its shaft, and after adjustment the cylinder is clamped in its bushing 62 (secured to the fountain) by a clamping screw 81 whose internally threaded shaft 82 also has a square head adjacent the head 80. A third mounting-point for the fountain is provided centrally of its rear edge by a block 90, Fig. 3, pivoted to a lug 91, Fig. 5, projecting from the trough 34; a tongue 93 controlled by a thumbscrew enters a slot 95 in the block and clamps it to an extension 50a of the base-plate 50; when the roller 33 is to be applied to the roller 25, the block 90 is turned through 90 degrees to raise the fountain and the tongue 93 enters a slot 96. The base-plate 50 has legs 51, 52 at its ends forming dovetails which are gripped between a fixed front bar 42 and rear members 43 located by bolts 45.
