Abstract: 1,079,874. Sheet forming. ITALMEC ALTO MILANESE S.p.A., and FARMOGRAFICA S.p.A. April 12, 1965 [June 3, 1964; March 5, 1965], No. 15441/65. Heading B5A. [Also in Division B8] A thermoplastic container 1, Fig. 1, comprises a plurality of small troughs 2, communicating with a common recess 5, in which small bottles, vials &c. are packaged, the container being closed by a flat plastics sheet 7<SP>1</SP> welded to the periphery of the container. The container is made in an apparatus in which a web 11, Fig. 1<SP>1</SP>, is heated and then moulded to produce a series of containers 1 which are filled and closed by applying a further web 28, the two webs being welded together and trimmed. In the embodiment, a plastics web 11, Fig. 1<SP>1</SP>, is fed intermittently by water-cooled clamps 15 through a cleaning and flattening station, where it passes between felt pads 17 and rollers 18, and then through a heating oven (54), Fig. 4 (not shown), comprising a combination of infra-red radiant heaters (53), Fig. 2 (not shown), and warm or cold air injectors (52). A water-cooled screen (not shown) can be partially or totally inserted in the oven to control the extent of the web which is heated or, if necessary, to completely insulate the web from the oven. The web next passes an air-cooled screen (55) into the moulding zone where the containers are formed by vacuum, or compressed air. Vials, fed from one or more adjustably inclined hoppers 45, 46, are then supplied to the formed containers. A detector 26, situated before the hoppers, detects the presence or absence of the moulded web and, in its absence, causes a screen to be inserted across the bottom of the hopper. A covering web 28, fed from a reel 29, is then welded to the filled containers between heated welding jaws (72), (75), Fig. 6 (not shown), of the welding station 49 which are laterally adjustable so that different widths of containers can be made. The jaws may be covered with a film which prevents adhesion between the jaws and the molten plastics. Finally, the closed containers are fed through a lateral trimming station 47, in which adjustably spaced knives (81), (82), Fig. 7 (not shown), perform the trimming, the containers being held taught laterally by clamps 42. These clamps 42 then release the containers which are then gripped by grippers 47 and taken through a transverse cutting station which trims and separates the containers, knives 34, co-operating with knives 35 performing this action. The finished containers are then discharged through shoot 37.

Title: Improvements in or relating to semiconductor devices
Inventor: CONNELL LESLIE JAMES CAMBRIDGE
IPC: H01L23/26
Filed: 1955-05-27
Abstract: 827,068. Semi-conductor devices. GENERAL ELECTRIC CO. Ltd. Aug. 24, 1956 [May 27, 1955], No. 15475/55. Class 37. In a method of making a semi-conductor device comprising a semi-conductor body containing at least one PN junction, a material which removes adsorbed water is applied to at least the exposed boundary of the PN junction, and the body encapsulated in an hermetically sealed container. Suitable materials are dimethyldichlorosilane, vinyl trichlorosilane, methyltriethoxysilane, and dimethyl diethoxysilane. Apart from the application of the water removing material the method of making such a device is the same as that described in detail in Specification 785,467 to which the present Specification refers. In brief a copper plate, solder layer, N-type germanium body of 10 ohm cm. resistivity, and the end of a nickel wire about which an indium bead has been moulded, are superposed in a jig, heated to 550� C. in hydrogen and then allowed to cool. A small amount of dimethyldichlorosilane is then brushed over the periphery of the indium bead to remove adsorbed water from the PN junction thus formed and to form a water-repellent layer. The periphery of the copper plate is then sealed to the open end of a copper cap through which a nickel tube, which is threaded over the nickel wire, is sealed by a glass-to-metal seal. The nickel wire is then sealed in the tube. As an alternative the dimethyl dichlorosilane may be applied to the inside of the copper cap just before sealing instead of to the PN junction. In this case it is thought that it migrates towards the junction afterwards to produce the same effect as direct application. Specification 775,121. also is referred to.

The ratchet teeth are fast on spindle a. Bolts e<1> project from lever b into a frame member d, in a hollow in which is a spring d' which acts on these bolts to return the lever b to mid-position. A snug d<1> projects from frame d between the pawls which, during a stroke of the lever b, lifts the inoperative pawl clear of the teeth which are advanced towards it. In a form shown in Fig. 5, the pawls g<2>, g<3> are spaced apart on a control lever g, the stroke of which is limited by stops i<2> - - i<7> engaged by the heel of the inoperative pawl. Lever h, which carries the ratchet teeth h<1>, h<2>, can be moved two steps at a time by deflecting lever g so that one of the stops i<2> - - i<7> is missed. A construction is described in which a single pawl is operative for stepped rises in the speed, the return control-operation being effected directly through a linkage in a single stroke.
