Filed: 1946-11-21
Abstract: 623,770. Wave-guides ; duplex radio signalling. COOP, E. Nov. 21, 1946, No. 34518. [Class 40 (v)] A wave-guide in a common transmitting and receiving aerial system comprises means for launching or receiving H waves polarized in one plane, means for receiving or launching E waves and means for transforming H waves polarized in a plane perpendicular to the plane of polarization of the first H waves into E waves. As shown, a wave-guide 1 in a common transmitting and receiving aerial system is fed from a transmitter by a probe 2 arranged to launch horizontally polarized H<11> waves. Vertically polarized H<11> waves received from a distant station are transformed by a semicylindrical block 4 of dielectric material to give an E0 wave which excites the receiving probe 3 mounted in a semicylindrical groove in the block 4. The flat surface of the dielectric block 4 is arranged parallel to the transmitting probe 2 so that the transmitted H<11> waves are not affected by the block 4 and do not excite the probe 3. A tuning piston 5 serves to orientate the block 4 correctly and to maintain proper matching. A similar arrangement, having a vertical transmitting probe, is used at the other station, which transmits vertically polarized H<11> waves, and receives horizontally polarized H" waves, transforming them to E0 waves. Specification 597,251 is referred to.

The body may be formed from a single strip having alternating generally plane and overall corrugated regions, folded zig-zag fashion, or as in Fig. 3 may be a stack of alternate generally plane sheets 18 and corrugated sheets 19, each having smaller corrugations 12. A strip having intermittent large corrugations may be coiled to produce a body which going radially has alternate generally plane and overall corrugated layers. In another form, Fig. 5, a strip has a generally plane region, and an overall corrugated region, and is folded about the junction between the regions and then coiled from that junction. The corrugations may be of U- or V-section, or semisoidal, and the corrugations of successive layers may be parallel or inclined. The strip may be of aluminium-bearing ferritic steel, or a ceramic such as alumina or silicon nitride, or a ferro-electric material e.g. lanthanum barium titanate. The catalytic material may be platinum or palladium, which may be deposited onto a gel fired on the body surface, by vapour deposition, sputtering, or wash coating from a slurry. In an example, a body as in Fig. 3 is made from alloy of composition 15% Cr, 4% Al, 0.3% Y, remainder Fe. An alumina layer is formed on its surface by heating in air to 1000C for 24 hours. The body is then dipped into an alumina sol and allowed to dry, and the temperature raised by about 300C/hr to 1100C at which it is held for 4 hours. Platinum is then deposited. The strip may alternatively be oxidised before forming the body, and the alumina sol may contain a wetting agent and a binder.

Abstract: 1501671 Burners ALLIS-CHALMERS CORP 21 Aug 1975 [4 Sept 1974] 34794/75 Heading F4T A fluid-delivery nozzle 20 for a rotary orereducing kiln 10 comprises a hollow elongated body 22 to be mounted on the outside of the kiln to rotate therewith, closed at one end to form a chamber 75 connectible to a fluid source, a hollow sleeve 36 extending through body 22, a nozzle tip 40 having a fluid passage 42 therethrough, a liquid fuel tube 38 slidably received within sleeve 36 and connectible to a liquid fuel supply 68, an inlet port 62 in the nozzle body, and an outlet port 64 which communicates with nozzle chamber 75 for the passage of gaseous fluid. There may be more than a hundred nozzles 20 circumferentially and axially spaced on the surface of the kiln. In operation, methane may be used as the reductant so that as a given nozzle 20 rotates with the kiln, beneath the bed of ore, the gas enters port 62, passes into chamber 75 and out through port 64. As the nozzle moves from beneath the bed, port 62 is disconnected, and when the nozzle reaches an elevated position above the bed of ore, port 62 is connected to a source of oxidizing gas. Instead of using gas as the reductant however, oil may be supplied through oil tube 38 and passes into the kiln through passages 39, 41, 42 and orifice 60, the oxidizing gas being supplied through ports 62, 64, as before, the fuel and gas supply being controlled by a valving system. Oil tube 38 is adjustable in sleeve 36 and can be reciprocated therein in order to clean the nozzle, or removed so that a cleaning rod or a different oil tube can be inserted. Ore is prevented from entering chamber 75 by a baffle 70. In a modification, the nozzle tip is mounted substantially flush with the inner bore of the kiln and the gases discharge through ports (112) in a direction parallel to the axis of the nozzle Figs. 2, 3 (not shown). The oil tube 38 and sleeve 36, are cooled by the oxidizing gas (air) which passes through chamber 75.

Title: Improved process and apparatus for drying and impregnating in vacuo particularly applicable to the manufacture of insulating materials
IPC: H01B13/30
Filed: 1927-12-23
Abstract: 308,641. Griffiths, H., and Passburg, E. Dec. 23, 1927. Impregnating for electric insulation.-Insulating materials are dried in two stages, most of the water being removed in a vacuum of the order of the vapour pressure of water at condenser temperature, e.g. 24 m.m., and the remainder under a high vacuum, e.g. 5 m.m., and are then impregnated. After heating at atmospheric pressure and in the lower vacuum, the drying at the higher vacuum obtained by pumps or steam ejectors is assisted by refrigeration in a surface condenser to 0‹C, or absorption of the moisture by a cold liquid, e.g. brine or by a dehydrating substance, e.g. solid calcium chloride, sulphuric acid or phosphorus pentoxide, or absorbent carbon or colloidal silica. After impregnation in vacuo, the materials are impregnated under pressure. Two or more vacuum chambers 10, 11 are operated alternately, being heated by steam pipes or jackets, and connected with surface, jet or barometric condensers 15, 16. Pipes 24, 20 and 20, 22 with cocks connect the condensers in turn with low and high cylinders 19, 18 of a vacuum pipe 17. The higher vacuum is obtained by a single or multi-stage reciprocating or rotary oil immersed pump working preferably in series with the low vacuum cylinder 19 or by a steam jet ejector, e.g. worked in series with one or more steam ejector or other vacuum pumps. When no more water is seen by an inspection plate to flow in pipe 24 while exhausting chamber 10 by the low vacuum cylinder 19, the chamber is connected to high vacuum cylinder 18 until newly condensed water again ceases to flow. After repetition, hot impregnating material is introduced and air again removed. Chamber 11 is loaded while chamber 10 is exhausted by the low pressure cylinder 19, and one chamber may be under the lesser vacuum while the other is under high vacuum. Both pumps may be worked first under low then under high vacuum. Water absorbent substances may be placed between the chamber and the pump.
