Title: Simultaneous preparation of saturated aliphatic hydrocarbons containing 1-4 c atoms, and benzene with its homologues, from light virgin naphtha
IPC: C10G45/68
Filed: 1966-07-19
Abstract: 1,133,263. Reforming naphtha; aromatic hydrocarbons; ethylene. STAMICARBON N.V. 19 July, 1966 [26 July, 1965], No. 32430/66. Heading C5E. A process for the conversion of light naphtha comprises contacting the light naphtha with hydrogen in the presence of a catalyst suitable for the dehydrogenation of organic materials under conditions of temperature and pressure and hydrogen/naphtha ratio so that at least half of the naphtha is converted to saturated C 1 -C 4  hydrocarbons and the remaining part into a liquid comprising at least 70% by weight of aromatics and further consisting mainly of saturated C 5  hydrocarbons. The aromatic fraction may be rectified to produce benzene, toluene, and a mixture of xylenes and ethylbenzene; the light hydrocarbons may be further cracked to produce ethylene. Suitable reforming catalysts are Cr, Mo, Pt or Pd on alumina, silica or silica-alumina. The cracking to ethylene is non-catalytic.

[Classes 17 (i) and 17 (ii).] A plurality of thin narrow strips 20, 22, Fig. 10, are secured to a heel block 12 in abutting edge to edge relation to give the appearance of a heel built up of lifts. The strips are cut crosswise. of the grain through leather stock 52 corresponding in thickness to leather heel lifts and are coated with adhesive, such as pyroxylin, and assembled in a shaping mould, Fig. 3, with wedge strips 54 to give a block having the contour of a piece of heel covering material. After moulding, thin skivings are cut from the moulded block in planes parallel to the top and bottom surfaces to form sheets of covering material. Woven fabric cut on the bias is preferably stuck to the block before each skiving is cut to provide a backing for the covering material, and is secured to the heel block, preferably by a rubber cement. The individual lifts may be finished in contrasting shades and the heels coated with celluloid solution and finished as desired. The covering material may extend around the breast face, as shown in Fig. 10, with a joint 26 in the middle, or the breast face may be covered by a similar skiving cut from a similarly prepared block, or by a separate cover which may form part of the sole. A block from which two heel coverings may be skived simultaneously may be prepared, if desired. Specification 238,134, [Class 17 (ii), Boots and shoes, Construction of], is referred to.

Title: Improvements in or relating to frame-aerial systems
IPC: G01S1/02
Filed: 1948-12-20
Abstract: 657,343. Aerials. PHILIPS ELECTRICAL, Ltd. Dec. 20, 1948, No. 32855. Convention date, Dec. 23, 1947. Addition to 656,887. [Class 40 (vii)] An aerial system comprises a plurality of aerials of the type described in the parent Specification and each comprising a central loop aerial surrounded by a plurality of metal plates forming effective short-circuited loops lying in the plane of the central loop, the loops aerials all lying in the same plane and adjacent loop aerials being coupled to a common conducting plate. Fig. 1 illustrates an aerial system for transmitting overlapping-beam beacon signals, the central loop aerial 2 being supplied with carrier-wave signal, while the aerials 1 and 3 are supplied with suitably phased side-band signals corresponding to the modulation tones being employed. Metal plates which behave as short-circuited loops are arranged around the primary aerials as shown. As indicated in the Figures, the couplings between each common conductor and the conductors adjacent thereto are made less than those between the other conductors and those between the conductors and the loop aerials. In the arrangement shown in Fig. 2, the central loop aerial is fed with carrier-wave signals while the aerials 14, 15, 16 and 17 are fed with side-band energy which is so phased that a continuouslyrotating directivity pattern is obtained. With this arrangement primary aerials of small dimensions may be used so that the configurations shown may be obtained; thus it is stated that in a prior art system utilizing socalled Alford Loops, the outer loops of three, as shown in Fig. 1, had to be so large that no room existed for the central loop which had consequently to be split into two, one above and one below the plane of the outer loops. It is also stated that the arrangements illustrated exhibit wide-band properties. The invention may also be applied to the overlapping beam direction-finder system described in Specification 655,678.

Title: Finely divided carbides and process for their production
IPC: C01B31/30
Filed: 1964-08-13
Abstract: Finely dispersed, e.g. 0.01 to 0.1 m  particles, non-pyrophoric carbides of the elements Ti, Zr, Hf, V, Nb, Ta, Mo, W, Th, U, B, Si, are prepared by subjecting a halide of one of the said elements and a hydrocarbon, both in the gaseous state, to the action of a hydrogen plasma jet at 2000 DEG  to 5000 DEG  C. for from 10-4 to 10-2 seconds. The halides may be the most highly halogenated, e.g. BCl3, SiCl4, TiCl4, ZrCl4, HfCl4, VCl4, NbCl5, TaCl5, MoCl5, WCl5, WCl6, ThCl6, UCl4. Hydrocarbons may contain 1 to 6 carbon atoms and may be methane, propane, butane, hexane, acetylene, ethylene, propene-1, diacetylene, butadiene, benzene, xylene, naphthalene.  The two components may be injected into the plasma jet together or separately, and a carrier gas such as argon or hydrogen may be used. In the Figure (not shown) the plasma jet is produced with an electric, high amperage arc in a generator consisting of a water-cooled, hollow, copper anode 3, and a water-cooled tungsten cathode 2 which has a variable position.  Hydrogen is introduced through 1 and the other reactants injected into plasma jet 4 at a position near the anode, e.g. 1 1/2 cms. away, through inlet 8, say with a quartz-feed duct.  The carbides collected in reaction chamber 6 may be further treated to reduce volume and to remove impurities by rotating for several hours, calcining under 10-1 to 10-4 mm.  Hg pressure or in the presence of hydrogen at e.g. 900 DEG  to 1000 DEG C.  Mixed carbides may be produced, e.g. TiC/TaC, TiC/VC, TaC/W2C.

Filed: 1977-08-08
Abstract: 1526719 Determining power distribution ELECTRIC POWER RESEARCH INSTITUTE Inc 8 Aug 1977 [6 May 1977] 3311777 Heading G6C A device for determining the recent power distribution in a reactor fuel element comprises a medium 14, e.g. beryllium oxide or a deuterium compound which converts the pattern of gamma radiation above a predetermined energy threshold emitted by the fuel element into a corresponding neutron flux pattern, and an activant 16, e.g. of gold, silver, manganese or lutetium which produces a corresponding pattern of a long half-life radioactive isotope. The last pattern may be measured by conventional means after removal of the device from the element. The gamma radiation pattern is produced by short-lived La 140 which in turn is produced by short-lived Ba 140. Since production of Ba 140 depends on power, and since the La 140 does not migrate within the element, the La 140 distribution represents the recent power distribution of the element.
