Title: Improved process of preparing selenium to which is added small quantities of substances for the purpose of increasing its conductivity
IPC: H01L21/10
Filed: 1946-09-27
Abstract: Selenium, which has added thereto a small quantity of a substance, which is hygroscopic or decomposes in air and increases the conductivity, is produced by adding the constituent in the form of a non-hygroscopic complex compound which does not decompose in air and from which the constituent is obtained by heating at a high temperature.  Suitable constituents are metallic halides which change into oxide on treatment with water or alkali, and air stable complexes may be obtained therefrom by combination with other halides such as alkali metal or ammonium halides, e.g. ammonium hexabromo-stannite and potassium chlorotitanate.  The complex may be stirred with molten selenium, the vapour from heating the complex may be conducted by gas stream into molten selenium, or a mixture of complex and selenium may be distilled.  Selenium containing constituent alone may be obtained in either of the last two methods where the constituent is more volatile than the substance with which the complex is formed or alternatively, the latter may also increase the conductivity of the selenium.  Specification 486,829, [Group XXXVI], is referred to.

Abstract: 319,669. Chicago Pneumatic Tool Co., (Assignees of Stevens, E. W.). Sept. 25, 1928, [Convention date]. Percussive hand tools.-An extension of the handle 7 is screwed to the cylinder 3 and holds in position valve-chest parts 8, 9 supporting a sleeve valve 10 which is made of three dimensions 10<a>, 10<b>, 10<c> to provide four pressure areas comprising the two ends of the valve and the two faces of 'flange 10<c>. With the valve in the position shown in Fig. 1, fluid enters the cylinder by ports 11. 11<a> and passes to the rear end of the cylinder by a bye-pass 12. The forward cylinder end exhausts through passage 13, ports 13a, valveflange rear chamber and the outlet 14. When port 15<a> is uncovered, cylinder fluid passes to the forward face of the flange 10<c>, impinging thereon through the restricted port 15<b>, and partly or wholly reverses the valve against the pressure on the annular rear area. The supply port 16<a> is opened by the flange 10<c> and the fluid pressure where necessary quickly finishes the valve reversal and passes to the forward end of the cylinder by ports 13<b>. The rear cylinder end exhausts through ports 14b and passage 14. When the piston closes the ports 14b during the return stroke, the compression produced passes by the passage 12 to the rear cylinder end and together with the reduction in pressure on the flange 10<c> produced by opening the port 15a to the forward end of the cylinder, effects the valve reversal.

Abstract: 1,109,581. Packaging-machines. JACOB, WHITE & CO. Ltd, 4 July, 1966 [12 July, 1965], No. 29442/65. Heading B8C. Collapsed cartons 1 are fed from a hopper 2. by vacuum suckers 11, 15, mounted on a cross bar 10 and. a pair of arms 14, respectively; carried by a bar 9 which is reciprocated by a rod 6 connected to a shaft 4. The arms 14, on lowering the bar 9, are pivoted under the action of at follower 17 in a cam slot 18, and the vacuum is removed from the suckers, to deposit the collapsed carton into at frame 24a which has been pivoted, under the action of the shaft 4; to lie back Fig. 3 (not shown), in the shoot (27). On receiving a collapsed carton, the frame 24a is pivoted back to the position as shown, where the carton is held by suckers 33 on plates 32 on the ends of arms 31, which arms, e.g. eight, are mounted on a continuously rotating spindle 29. Eaeh plate 32 is also provided with leading and trailing walls (35); (34), respectively, Fig. 2. (not. shown), to define a box-like structure having open top, bottom, and radially outward walls. The leading wall (35) is hinged, and is closed by a cam-operated and spring-loaded' push-rod (36). The wall. (35) is open when the collapsed carton is received from the frame 24a. As the arms 31 revolve, the wall (35) slowly closes, forcing the carton, still retained by the suckers; into an erect position. The bottom flaps of the carton. are then folded and' glued in. any conventional manner, e.g. by ploughs. Above the arms 31 is mounted a disc 42 on a spindle 41, and having radial slots, e.g. six, in which slide spring loaded and cam-operated brackets 43, each of which carries a funnel 44. The funnels may thus be brought into register above a carton to deposit a weighed or measured amount of material therein. The inner flap 48 of the carton may be held down, e.g. by a plough. The carton may rest on a vibrating rail 49 to shake the carton contents. The suckers 32 would thus have to be mounted to facilitate such vibration, e.g. on reeds. The carton top flaps are then folded and glued by any conventional means. The carton is dispensed by releasing the vacuum from suckers 32 and opening wall (35), whereupon the carton strikes a bar (47), and is removed. Adjustments to enable various sizes of cartons to be handled may be made.
