Title: Improvements in or relating to cable communication systems
IPC: H04B3/34
Filed: 1933-03-23
Abstract: 417,054. Wired wireless signalling. STANDARD TELEPHONES & CABLES, Ltd., Connaught House, Aldwych, London.- (Western Electric Co., Inc. ; 195, Broadway, New York, U.S.A.) March 23, 1933, No. 8776. [Class 40 (v).] In a transmission system having a plurality of conductors arranged in a plurality of separate cables or shielded compartments of the same cable and repeaters therefor, the intervals between the repeaters varying with different individual conductors, in order to minimize cross-talk the conductors either of the repeatered line or of adjacent lines are transposed into a separate cable or section in the neighbourhood of a repeater. In a system employing two cables I, II, Fig. 1, the carrier-frequency conductors e, f respectively are repeatered at a station B the voice-frequency lines of cable I being transposed to cable II at this point and vice versa. In order that conductor pairs a, b entering cable I and pairs c, d entering cable II at A may leave the same cable at C further transpositions are effected as shown at points A<1> and C<1>, this particular arrangement ensuring the least interference with traffic should one of the cables be damaged at any point, the pairs a and c forming a four wire system with terminal a<1> and pairs band d forming a similar system with terminal at b<1>. The points A<1> and C<1> should be as far apart as other conditions will allow. In a system embodying a single cable with internal shield, the carrier-frequency lines e, f, Fig. 3, and voice-frequency pairs a, b, c, d are arranged so that the inputs from the repeaters at A and C are directed into the outer compartment and each repeater receives its input from an inner compartment. The repeaters at B in the carrier-frequency lines are so arranged that their inputs come from the inner compartment and the high level output circuit is in the outer compartment. The voice frequency circuits may be confined to a single compartment as shown in dotted lines.

Patent GB-740634-A (GB)
Title: Method of carrying out catalytic reactions
IPC: C01B3/46
Filed: 1953-03-31
Abstract: In a cyclic catalytic process involving heating a stationary catalyst zone containing an easily oxidisable metal by the passage of hot gases therethrough, and then passing reactants through the catalyst to effect an endothermic reaction, heat is supplied by passing free oxygen through the catalyst zone to convert the metal to its oxide, and then passing an oxidisable gas through the zone to reduce the oxide to metal, the amount of oxygen used being controlled so that the temperature difference between the entrance and exit portions of the catalyst zone is less than about 475 DEG F and the maximum temperature reached is below the sintering temperature of the catalyst.  The hot gases may be produced by burning a fuel, e.g. natural gas, liquid hydrocarbons, water gas, producer gas, or oil gas; if the gases contain excess oxygen they are suitable for the oxidation step in the process, while if they are the result of combustion with insufficient air, they may be used in the reduction step. Reduction may also be carried out with hydrogen, carbon monoxide, or gaseous hydrocarbons, e.g. methane; nitrogen or carbon dioxide may be present as a diluent.  A suitable catalyst is nickel or cobalt supported on a porous carrier; alumina, silica, magnesia, calcium oxide, titanium oxide, chromium oxide, thoria, ceria, and chromates or silicates, e.g. zirconium silicate, may also be present in the catalyst.  The invention is described with reference to the reaction of hydrocarbons and steam to form a combustible gas containing hydrogen and carbon monoxide; in this case the volume of oxygen used in the oxidation step is 15-180 cubic feet per 1000 cubic feet of hydrogen and carbon monoxide produced.  The hydrocarbon reactant may be natural gas, refinery oil gas, methane, ethane, propane, butane, gasoline, or gas oil and may contain ethylene, propylene, or butylene; air may be present during the reaction which takes place at 1500 DEG F or higher for methane, or at a lower temperature for higher hydrocarbons.  Reduction of the catalyst can be effected with the hydrocarbon reactant.  An example describes the reaction of natural gas and steam in the presence of nickel-coated spheres of aluminium oxide, using varying amounts of oxygen for the oxidation.  Reference is also made to processes for the desulphurisation of hydrocarbons, cracking of liquid hydrocarbons to gaseous hydrocarbons, cracking of heavy liquid hydrocarbons into light liquid hydrocarbons such as gasoline, and the conversion of paraffinic hydrocarbons into aromatic hydrocarbons.

Title: Process for cooling hydrocarbon mixtures
IPC: C07C7/11
Filed: 1962-03-09
Abstract: <PICT:0955580/C3/1> The formation of ice and/or solid hydrocarbon hydrates during the cooling of fluid mixtures containing liquid hydrocarbons and water to below the freezing point of water is prevented by adding sufficient ammonia to the system to obtain an ammonia-water solution which is liquid at the temperature and an ammonia-hydrocarbon solution in equilibrium with the ammonia-water solution.  The process is of particular value when cooling and compressing normally gaseous hydrocarbons prior to distillation and in the pretreatment of pyrolysis gases containing acetylene with cold naphtha to cool and dry the gas and to remove C3 and higher unsaturated hydrocarbons prior to recovery of the acetylene by absorption, e.g. in liquid ammonia.  The amount of ammonia required to prevent freezing is shown by the ammonia-water phase diagram of Fig. 2 in which the area K represents conditions in which no solid is present.

Abstract: 417,461. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, PATTERSON, W. G., 59, Grove Park Road, Mottingham, both in London, and LONG, D. P., 3, Ingleby Way, Chislehurst, Kent. April 3, 1933, No. 9930. [Class 40 (iv).] A single-motion selector is adapted to actuate a statistical meter in dependence on the setting on a digit switch by the passage of one of its wipers over an auxiliary contact at the beginning or end of its bank. The invention is described as applied to the final selector adapted for P.B.X. hunting shown in Figs. 2, 3 of Specification 412,722. Auxiliary contacts at the beginning of the marking banks (FS 8, 9) of the selector may be connected to earth as desired either directly or via a particular contact or contacts of the marking banks of the digit switch. A relay (R) which is disconnected when the selector is started holds up until after the auxiliary contact is passed to permit the momentary operation of a relay TM, Fig. 3, common to a group or sub-group of selectors. Relay MT energizes and actuates the meter M which releases MT. The meter may thus record the whole traffic over the selectors, or the traffic over a particular line or P.B.X. group or any desired aggregation of lines. Auxiliary contacts at the ends of the banks may be similarly connected to earth as desired in order to control the actuation of a meter to record all unsuccessful searches made by the selectors, or the unsuccessful searches for a particular line or group or any desired aggregation of lines. In this case also, relay TM operates momentarily, since the selector moves round to normal when no idle marked line is found. Alternatively, the last position or positions of the selector may be wired to route unsuccessful calls to an operator in the case of certain desired numbers, in which case a recording position could precede such positions. Figs. 4, 4A show the addition of an auxiliary contact 5 clamped to the ebonite block 13 at either end of the bank, a dummy contact 6 being interposed between that contact and the ordinary contacts 4 to preserve the continuity of the bank.
