[Class 8 (ii).] Liquefied gas contained in a storage vessel 3 is vaporized in a vessel 2 surrounding the storage vessel from which it is delivered through a siphon 11 under the pressure of the gas above the liquid level; a valved pipe 12 connecting the two vessels their difference of pressure to be adjusted and so also the rate of flow of liquid. An apertured sheath 6 is provided to cause a flow of cold gas along the wall and to limit evaporation when the apparatus is out of use. Vaporization is effected by a current of air, which may be warmed, or other fluid passing through ports 23, 24 in the outer casing 1, which are controlled by slides. The gas is delivered to points 15 for utilization, or to a gas-holder 17.

An A.C. input energizes a resetting type transductor 29 comprising a single core with but one winding 27, the core flux being set by load current half-cycles of one polarity passed through the winding, a load current rectifier 31 and a load 17, while the flux is reset by current passed through the winding and a thyristor 35 during the half-cycles of the other polarity, the duration of the current within the reset halfcycles, and hence the degree of flux resetting, being determined by a control signal applied from a voltage control device 37 to the thyristor. In the arrangement shown, controlled three-phase full wave rectified current is established in a common load by three identical transductor units 10, 11, 12 each connected to a different phase of a three-phase supply 16. Each transductor unit comprises two transductors 29, 30, associated load current rectifiers 31, 32 and thyristors 35, 36, the transductors being energized from a centre-tapped transformer 19 so as to pass full wave rectified current to the load.

Abstract: 1330538 Continuous casting MONSANTO CO 27 July 1970 [28 July 1969] 36321/70 Heading B3F [Also in Divisions C1 and F4] To produce wire, molten metal 1 such as copper, steel or stainless steel plus 1% aluminium, is spun as a jet 13 through an orifice 11 in a part 3 of a crucible assembly or crucible 2 in which a charge of metal is heated (e.g. melted by an induction coil 7 and a susceptor 6), the orificedefining member (which may be a base-plate 3 or an insert 12 in the plate) being a single crystal of BeO or a material which is at least 99À5% polycrystalline BeO and of a density greater than 95% of the theoretical density for BeO. The orifice 11 is formed by machining a countersink recess in the face of a beryllia plate and then drilling and polishing the orifice to be coaxial with the recess. Alternatively, a polycrystalline beryllia plate is prepared by a bisque process, being shaped and drilled before final firing to a required density and then polished. The orifice is less than 35 mils in diameter and has a length/diameter ratio between 1 and 20. There may be several insert discs in the crucible base-plate. They may be clamped in the plate or held down by a ring. The orifices may be tapered and lead from a tapered countersink. Stainless steel plus 1% Al may be melted in the crucible 2 in a vacuum and argon under pressure applied by way of an inlet 8 to force the melt into a chamber 14 containing CO which forms a layer on the jet to stabilize it until it solidifies. The apparatus is in an insulating cylinder 5. A one-piece BeO crucible may be used for spinning molten copper into propane.

Filed: 1932-12-23
Abstract: An oxychloride cement is prepared by mixing magnesium oxide or calcined magnesite and sufficient of a solution of magnesium chloride and magnesium bromide to render it plastic and allowing it to set. Instead of a synthetic mixture of magnesium chloride and bromide, the residual liquid resulting from the abstraction of salt from sea water by the solar method may be used, the specific gravity being preferably between 19 to 22 Baume.  The usual fillers such as sawdust and the usual aggregates such as sand and gravel may be added.  The product may be used for walls and floors or for roads, or cast into moulds to form blocks.  When colours are added to the mixture it is necessary to add a small amount of zinc oxide to prevent the colours from running.  In an example 1/4 cubic yard of calcined magnesite, 1 cubic yard sand, and 35 gallons sea water residual are mixed to a plastic state and allowed to set.

Abstract: 1,066,431. Discharge lamps. HILGER & WATTS Ltd. Sept. 26, 1963 [Sept. 27, 1962], No. 36715/62. Heading H1D. [Also in Divisions G1 and G2] Samples of metal products are analysed by melting them and then examining them spectrometrically in the same equipment. The crucible 10, Fig. 1, forms the anode of an analytical gap 10, 14, across which are applied two different discharges which are temporally spaced. The generators (36), (38), Fig. 2 (not shown), are fed from the mains through transformers (40), (42), which are 180 degrees out of phase with one another. A pulse generator (32), locked to the 50 c/s. mains, provides a pulse at (34a) during the negative half-cycle of the mains reference voltage and fires the thyratron (44), inducing an overvoltage in Tesla transformer (46) coupled to the analytical gap 10, 14, through capacitor (48). A gap (55), having a higher breakdown voltage than gap 10, 14, isolates generator (38) from the analytical gap and generator (36) during this half-cycle, but current flows from transformer (42) through rectifier (56) to charge capacitor (58). During the positive half-cycle of the mains reference voltage, a pulse appears at (34b) to fire thyratron (60) and induce an over-voltage in Tesla transformer (62). This is sufficient to break down gap (55) and produce a discharge across analytical gap 10, 14, together with the current flow from capacitor (58). The inductance (54) and capacitor (70) isolate generator (36) from the gap 10, 14. The long duration pulses from generator (36) serve to melt the sample S in crucible 10 and the sharp pulses from generator (38) cause spectrum emission. A shutter 28 may rotate in synchronism with the pulses so that radiation is only passed to the spectrometer during the operation of generator (38). In a modification, time resolution of the emissions produced is obtained by gating the spectrometer receiving devices such as photomultipliers. The crucible 10 may be heated by an induction coil or dielectric heating and two or more different types of analytical discharge may be provided. The discharges may be initiated by trigatrons, relays or rotary switches or the analytical gap may be momentarily shorted. The crucible and counter-electrode holders 8, 12 are water-cooled.
