Title: Generation of gaseous mixtures of carbon monoxide and hydrogen
Inventor: GUPTILL FRANK EDWARD
IPC: C09C1/58
Filed: 1963-07-08
Abstract: A process for generating a CO- and H2-containing gas mixture comprises forming a slurry of 0.5% to 3.0% by weight carbon black in water, vaporizing the water, suspending hydrocarbon liquid in droplet form in the vapour whereby transfer of the carbon to the droplets occurs, and introducing the resultant dispersion into a reaction zone with an oxygen-containing gas, e.g. pure oxygen, for conversion to the required combustible gas, e.g. at 1800 DEG  to 3500 DEG  F. and 100 to 600 p.s.i.g.  The slurry may be formed by washing the product gas with water, e.g. at 200 DEG  to 450 DEG  F., and passing it through a tubular heating coil for vaporization. Hydrocarbon oil is introduced while the vapour/carbon stream is moving at above 20 feet/second, and the stream enters an elongated tubular contacting zone, which may be heated, to effect transfer of the carbon to the oil droplets. In this zone, preheating of the oil/steam/carbon dispersion to 750 DEG  F., with partial vaporization of the oil, takes place.  Relative proportions by weight of steam to oil may be 0.2 to 2, preferably 0.4 to 1.  A specific example, using Los Angeles Bunker C fuel is described. Specification 827,474 is referred to.

Abstract: 684,200. Aerials. BELLING & LEE, Ltd. Oct. 1, 1951 [Nov. 6, 1950], No. 27093/50. Class 40 (vii). A directional aerial array includes a plurality of half-wave elements mounted with their centres in line, the elements being inclined to the line of centres of an angle of between 45 and 90 degrees so that, if the line of centres is horizontal and the elements lie in a vertical plane, vertically polarized radio signals whose wave front is inclined to the horizontal direction of propagation may be efficiently received. Some of the aerial elements may be parasitic and an array according to the invention may comprise a Yagi array, an end fire array, or an energized unit of a broadside array with its parasitic element. A Yagi array may comprise a dipole 1, mounted at its centre on a cross-arm 6 intended to be horizontal when in use, and connected to radio apparatus by feeder 2. Parallel to dipole 1 are two directors 3, 4, and a reflector 5; these parasitic elements may be electrically connected at their centres to the metallic cross-arm in accordance with Specification 519,883. The elements 1, 3, 4 and 5 are arranged to be at an angle of 75 degrees with the cross-arm in accordance with the present invention so as to lie substantially parallel to the signal wave front when receiving vertically polarized radio signals. The cross arm may be braced by strut 8 and wire 9 and supported by post 7.

Title: Process for the production of wax esters from fat alcohols
Inventor: KONIG EDGAR
IPC: C07C41/01
Filed: 1966-06-17
Abstract: Wax esters are prepared by treating saturated or unsaturated fat alcohols (12 or more C) with an activated catalyst comprising copper-zinc, copper-zinc-cadmium, or copper-zinc-cadmium-chromium at between 200 DEG  and 300 DEG  C., and removing the hydrogen formed during the reaction.  Carriers such as aluminium oxide, silica gel, and carbon may be present and the activation is by roasting the mixed carbonates formed by precipitation to give an oxide form, or by pre-reduction with hydrogen to give a mixed metal-metal oxide.  The reaction may be in the gaseous phase and continuous or liquid and intermittent.  Examples describe the treatment of lauryl alcohol to yield lauryl laurate, myristyl alcohol to yield myristyl myristate, cetyl alcohol to yield palmitic acid cetyl ester, octadecyl alcohol to yield stearic acid octadecyl ester, and hardened coconut oil alcohol, sterol (C18 and C16 alcohols), a fat alcohol of C12-C22, and a fat alcohol mixture from the hydrogenation of rape oil to form waxy esters.ALSO:Activated mixed contact catalysts comprising Cu-Zn, Cu-Zn-Cd, or Cu-Zn-Cd-Cr are used in the preparation of wax esters. The catalysts may be supported e.g. on aluminium oxide, silica, and carbon and the activation is by reacting the mixed carbonates formed by precipitation to give an oxide form, or by prereduction with hydrogen to give a mixed metal-metal oxide.

Title: Improvements in or relating to control systems for mercury arc rectifiers
IPC: H02M7/15
Filed: 1948-10-21
Abstract: 664,408. Rectifying. NEVELIN ELECTRIC CO., Ltd., and BERTELE, H. C. Oct. 21, 1949 [Oct. 21, 1948], No. 27418/48. Class 38 (ii). A grid control circuit for a mercury arc rectifier of the type comprising a saturable grid transformer includes an auxiliary D.C. supply circuit having an impedance therein which is common to the main D.C. saturating current supply circuit, means for producing in the auxiliary circuit an auxiliary current which flows through the common impedance and means for automatically changing the value of the auxiliary current when the load current exceeds a predetermined value so that the auxiliary current acts in the common impedance to change the saturating current in the grid transformer thereby to change the point in the A.C. cycle at which the grid pulses occur so as to reduce the rectifier load to, or below, the predetermined value. A potentiometer 28 is connected across the output of a mercury arc rectifier 12, the saturating winding of the saturable grid transformer being supplied from an adjustable tapping 33 thereon through a reactor 34 and a resistor 35. The T-bridge comprising three resistors 35, 62, 65 has a number of voltages applied to it including a variable voltage from a rectifier 61, which is fed with A.C. through windings on a saturable reactor 58, and a fixed voltage from a rectifier 64 fed with A.C. from a constant voltage source 63. When the rectifier output current exceeds a safe value the saturating current in the saturable grid transformers is reduced by injecting into the resistance 35 an auxiliary current obtained by comparing in the T-bridge the output of the rectifier 61 with the output of the rectifier 64 ; thus the rectifier output current is reduced. The T-bridge can be dispensed with by the provision of another winding 101 on the saturable reactor 58, Fig. 4. In this embodiment the saturating current for the grid transformers is provided by the voltages derived from the rectifiers 76, 78 which act in opposition across the resistors 79, 80, the saturable reactor 58 being biased from the resistor 79. Again an increase in the rectifier output current beyond a predetermined value causes a reduction in the saturating current in the grid transformer and thus reduces the rectifier output. By the provision of a further system comprising another T- bridge, similar to that shown in Fig. 1, current surges in the output circuit on switching on may be avoided, Fig. 2 (not shown). In the embodiment in which the T-bridge is dispensed with switching surges may be avoided by the provision of a further saturable reactor, in series with the original reactor. A current transformer may be used in conjunction with the input connections to the rectifier 12 to obviate the need for a winding on the saturable reactor 58 to carry the output current. Specification 664,400, [Group XXXVIII], is referred to.
