Title: Improvements in and relating to the oxidation of aromatic hydrocarbons
Inventor: DOWDEN DENNIS ALBERT
IPC: C07C45/36
Filed: 1957-06-26
Abstract: The preparation of supported metal vanadyl vanadate catalysts of the type claimed in divisional Specification 883,315 is described.  In Example 2 an unsupported catalyst is prepared by grinding and fusing potassium carbonate and vanadium pentoxide, cooling the melt, when oxygen is evolved, grinding the solidified mass and converting the powder to pellets.ALSO:A process for the oxidation of monocyclic and bicyclic aromatic hydrocarbons to aliphatic and/or aromatic carboxylic acids and/or anhydrides thereof and/or ketones comprises passing the aromatic hydrocarbon in the vapour phase in admixture with a gas containing free oxygen but in the substantial absence of any other organic compound at an elevated temperature over an oxidation catalyst produced by a fusion process comprising a vanadyl vanadate, as hereinafter defined, of at least one metal selected from thallium, silver, potassium, sodium, lithium and rubidium.  The catalyst is a single solid phase or mixture of solid phases, produced by a fusion process, each phase containing thallium, silver, potassium, sodium, lithium or rubidium together with oxides of vanadium, wherein at least a part of the vanadium atoms have a valency of 5 and the remainder have a valency of from 2 to 4.  The catalyst may be prepared by fusing a suitable metal compound, e.g. thallium or potassium carbonate, with vanadium pentoxide and the product cooled during which time oxygen is evolved.  The product may be crushed and the powder used as such or made into pellets or it may be coated on a support such as silicon carbide, corundum, alumina or silica.  The vanadyl vanadate obtained after the oxygen evolution may be remelted and coated on a support or the molten catalyst may be coated on the support before the oxygen evolution. The oxidation may take place at 300 DEG C.-550 DEG C. using air as the oxidising agent. The examples describe the preparation of thallium, silver and potassium vanadyl vanadates and the oxidation of o-xylene to phthalic anhydride and of naphthalene to a mixture of phthalic anhydride, phthalic acid, maleic acid, benzoic acid and 1,4-naphtha-quinone. The oxidation of m- and pdi-isopropyl benzene to m- or pisopropyl benzoic acid and benzene to maleic acid or maleic anhydride is also mentioned.  Specification 883,315 is referred to.

Title: Lumped ore products and preparation thereof
IPC: C22B1/24
Filed: 1958-06-24
Abstract: Ores are agglomerated by the formation of an alkaline earth carbonate in situ.  The ore, which may contain metallic particles, is mixed with 2-8% by weight of an oxide and/or hydroxide of an alkaline earth metal such as magnesium, calcium, strontium, or barium and after pressing to shape is reacted at 50 pounds per square inch with carbon dioxide in the presence of up to 10% of moisture.  The reaction may be accelerated by the inclusion of a soluble salt such as a chloride, sulphate, or carbonate of an alkaline earth metal, alkali metal, or iron.  The process is particularly applicable to ores of iron, manganese and nickel.

Title: Improvements in or relating to switching arrangements for automatic or semi-automatic telephone systems
IPC: H04Q3/00
Filed: 1929-07-03
Abstract: 335,938. Standard Telephones & Cables, Ltd., and Baker, J. H. E. July 3, 1929. Automatic exchange systems.-In systems using bye-passing marking switches, it is arranged that for digits up to 5 the marking switch, acts simply as a marker and the connection is set up immediately over the conversation switch, while for digits greater than 5 the conversational switch acts as a marker to the marking switch which sets up a bye-pass connection. In a modification not described in detail a non- homing conversational switch is controlled by two bye-passing switches related to each other as are the conversational and marking switches in the - arrangement described in detail. Detailed operation. When the selector is seized, K therein pulls up in series with D in the common circuit followed by impulse relay A, release relay Band test relay E. A repeats the digit to CR and C in parallel. The relapse of E when CR moves makes a self-interrupting circuit for IR which races to its 20th terminals (where it is stopped by E) provided the digit is greater than 2. If however CR has stopped on its 1st or 2nd terminals, IR is stopped at the beginning of the corresponding group. F which pulled up its light armature f2 on the relapse of E operates fully on the relapse of C and operation of E, locks itself and releases E. If the digit is 3, 4 or 5, the relapse of C releases E to enable IR to advance from its 20th terminals to the group marked by CR whereupon E pulls up followed by F as in the case of digits 1 and 2 and then falls to start the hunting movement of IR under control of CH which, when an idle trunk is reached, energizes the twitching relay IH causing the release and restoration of the common apparatus. If all trunks are busy CH does not pull up and J pulls up over wiper M and the last terminal of the group and connects up busy-tone BT. If the digit is greater than 5, impulses in excess of this number are delivered, owing to the operation of G by CR on its 5th terminals, to IR instead of to CR. On its 1st step thereafter IR energizes H in series with E. H locks and makes a self-interrupting circuit for OR which advances to the beginning of the group marked by IR under control of E which is followed by F as before and then falls whereupon CR hunts for an idle trunk under control of CH, which switches through to the trunk, IH remaining unenergized in this case. CH also makes a self-interrupting driving circuit for IR which is stopped on the trunk selected by CR by E which is operated in a circuit over wipers M, N, and energizes IH. F (which is unlocked by C when IR starts) now pulls up again and locks E. IH switches through, breaking the bye-pass connection and the common apparatus is released and restored. Forced release. If the common circuit remains associated with the selector for the interval between two pulses on TP, P extends the pulse wire to IH which operates on the next pulse, unless CH has operated in the meantime, to cause the release of the common apparatus.
