Title: Process and apparatus for growing crystalline boules
IPC: C30B11/12
Filed: 1957-12-23
Abstract: <PICT:0844542/III/1> In a process for growing a crystalline boule an electric arc is formed between a stick electrode and a second electrode, a stream of gas is passed in contact with the stick electrode and the gas stream containing the arc is constricted to form an arc-heated collimated effluent which is directed together with the feed material for the formation of the boule into a boule growing zone. An arc is formed between a stick electrode 30 (Fig. 1) and a nozzle 28 surrounding electrode 30, or between the stick electrode 30 and a support rod 41. A gas stream passed down the nozzle 28 envelops the arc and is constricted through a passage 31. Powdered feed material from a source 11, or gaseous feed material from a conduit 16, is carried by a gas from conduit 16 through a conduit 18 to an annular passage 19, and then through multiple radial passageways 19a into a zone 26.  The material is then carried by hot gas to the boule-growing zone 23 where it is deposited on the support 41 to form a boule 43.  Alternatively, the feed material may be passed through the nozzle 28 with the gas stream, or the feed material may be introduced through a longitudinal passage in the stick electrode 30.  A seed crystal may be placed on the support 41. The support 41 is lowered as the boule 43 grows.  Nozzle 28 is cooled by water passed through an annular passage 32.  In examples a nickel boule is prepared from nickel powder, silicon boules from silicon powder and from silane gas, and a sapphire boule from alumina powder.

Abstract: 1,037,468. Ammunition. ATLAS CHEMICAL INDUSTRIES Inc. Oct. 2, 1964 [Oct. 3, 1963; May 4, 1964], No. 40343/64. Heading F3A. An electric igniting match is formed by a pair of trapezoidal metal tabs 11, 13, Fig. 2, to which conducting wires 17, 19 are soldered whilst a layer 12 of non-conducting material 12, e.g. fibre, asbestos or ceramic separates the tabs and a high-resistance bridge-wire 23 connects the tabs at the ends remote from the wires 17, 19; a match composition is moulded around the bridge wire. The composition includes, e.g. cuprous acetylide, diazodinitrophenol, lead mononitroresorcinate, a mixture of the latter and potassium chlorate, and silver or lead azides which are suspended in a lacquer, such as nitrocellulose. A semi-conductive element 29 also inter-connects the tabs 11, 13 and extends through the non-conducting material 12, which element is made of finely divided metal, e.g. aluminium, copper, lead or iron suspended in a matrix of high melting-point natural or synthetic wax; the wax may be replaced by polyethylene. An explosion initiator employing the above match consists of a copper, brass or aluminium shell 30, Fig. 3, with a base change 31 of pentaerythritol tetranitrate or tetryl, and a primer 33 of mannital hexanitrate or diazodinitrophenol above which is the match in a chamber lined 35 with paper, cardboard or plastic. The wires 17, 19 exit via a plug 37 of rubber or plastic. A delay element with a delay powder train may be interposed between the match and the primer: the delay train may comprise a powdered mixture of zirconium-nickel alloy and red lead. Any difference of high potential between the wires passes through the element 29 rather than the bridge wire 23 whilst any high potential on the wires is discharged to the the shell 30. When exposed to elevated temperature upon electric arcing in the initiator the element 29 partially meets and provides a low-resistance path between the wires.

Filed: 1974-09-20
Abstract: 1466306 Testing cables during extrusion GENERAL CABLE CORP 20 Sept 1974 41162/74 Heading B5A [Also in Division G1] To test the shielding of a cable, the cable is passed through an electrode maintained at a different potential from the cable conductor and deviations of the electrode/conductor impedance from normal indicate defects. In the extrusion of insulation around the stranded conductor 58 of a cable 56 having a semiconducting shield 60, the extrusion tip 14 and tip-holder 18 have an insulating layer 34 on their external surfaces to isolate them from the rest of the extrusion equipment. The tip has a discharge portion internal diameter substantially equal to the required diameter of shield 60 before the external insulation is extruded on to the outside. Any large increase in the shield diameter due to defects, i.e. "bird-caging" 62, "lumps" (Fig. 3, not shown) or "ballooning" (Fig. 4, not shown) causes the shield to be broken after passing through the tip (Fig. 5, not shown). The tip-ground resistance is measured by connecting the tip internal surface into a resistive bridge and grounding the conductor 58 (Fig. 1, not shown). The change in resistance due to the large compressive forces on the shield when defects are present or due to gaps in the shield, are detected and marked on a tape being driven longitudinally at a speed proportional to the speed of the cable through the extrusion machine. In an alternative embodiment, a conventional extrusion tip is used, isolated from the extrusion die by an insulating layer at the die/tip union (Fig. 8, not shown). In another embodiment, the tip has two isolated portions spaced longitudinally of the cable, the resistance of each to ground forming two legs of a resistive bridge, for fault indication (Fig. 9, not shown).
