Title: Improvements in or relating to telephone systems
Inventor: GALVIN JOHN LESLIE
IPC: H04M3/62
Filed: 1956-04-10
Abstract: 804,146. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. March 8, 1957 [April 10, 1956], No. 10838/56. Class 40 (4). A hybrid transformer at a tandem exchange is used to connect an operator over a 2-wire path to an outgoing 4-wire trunk and, when this connection is discarded, to connect the monitoring speech derived from a 4-wire path and applied to two wires on the 4-wire side of the transformer. A call incoming to the exchange and encountering delay working is routed to a suspend position where it is re-booked and subsequently established over the circuit illustrated by inserting jacks OJA, OJB, giving access to group selectors TGSA, TGSB. Sleeve relays operate at the selectors returning earth to operate relays ETA, ETB, which hold the sleeve relays over leads SI, ISI, connect up pentodes VA, VB to operate relays PA, PB, in their anode circuits, and connect up a double triode VC. Relay DR is also operated to postpone operation of relay FW. A connection to the called subscriber is set up over hybrid HB and leads IR, IT after which a connection to the call originating subscriber is set up over hybrid HA and leads R.T. When the latter subscriber replies selector TGSA returns a supervisory signal to the operator and, in response to restoration of the operator's speak-key, puts resistance battery on the lead to the upper winding of relay DR to cause its forcible release and in consequence the operation of relay FW which connects the subscribers together over transformers TRA, TRB, and disconnects hybrids HA, HB. Speech in the 4-wire circuit is extracted by third windings on transformers TRA, TRB and is amplified by double triode VC the output of each section of which is fed to the upper winding of hybrid HB now appropriately balanced by a contact of FW to enable the operator to monitor the line. The operator may also send pip-pip-tone to both subscribers by applying v.f. signals over hybrid HB to a transformer TRD connected to the grid of pentode VB, increased conduction through which biases pentode VA negatively to release relay PA and allow relay PP to energize and connect a tone of 900 c.p.s. to each outgoing line. The relay PB in the anode circuit of pentode VB, as with relay PA, provides supervision in that failure of either valve connects tone to the line to warn the operator.

Title: Desulphurisation of mercaptan-containing hydrocarbon gas
IPC: C10K1/34
Filed: 1965-03-16
Abstract: Mercaptans are removed from hydrocarbon-containing gases by oxidizing at below 50 DEG  C. to convert mercaptans to disulphides and contacting the resultant gas with a non-impregnated solid adsorbent. The gas may be a hydrocarbon, e.g. butane, or a cracking gas, refinery gas, natural gas, or fuel or town gas and may contain inert gases.  The oxidation is effected (a) by contact with an adsorbent such as activated charcoal impregnated with an oxidant, e.g. pyrogallol, hydroquinone, n-butyro-pyrogallol, anthragallol, gallic acid, tannic acid, 3,4-dioxydiphenol, 2,5-dioxydiphenol or butylpyrogallol and an inorganic or organic base.  The oxidant can be regenerated after reduction by contact with air or (b) by reaction with 0.1-0.5% by volume (based on hydrocarbon) of oxygen or ozone calculated as oxygen.  With oxygen a catalyst is also present on an adsorbent, e.g. a chloride, bromide, nitrate, or sulphate of Al, Cd, Cr, Co, Cu, Fe, Mn, Ni or Zn on activated carbon.  Ozone requires no catalyst but should not be used if olefins are present and the formation of ozonides is to be avoided.  The adsorbent in the second stage is preferably activated carbon or may be pumice, bog iron ore, bauxite or granular coke from lignite.  It may be regenerated by contact with steam, the disulphides being separated and recovered from the effluent.

Title: Improvements in or relating to the catalytic conversion of alkyl thiophenes
IPC: C07C7/148
Filed: 1957-04-05
Abstract: Alkyl thiophenes are passed at elevated temperature in contact with a catalyst produced by impregnation of alumina with hydrofluoric acid in aqueous solution, the alumina being in catalytically active form or in a form capable, after impregnation, of conversion to a catalytically active form and being so converted.  The alkyl thiophenes may be (a) dealkylated to form lower alkyl thiophenes and/or unsubstituted thiophene, (b) simultaneously dealkylated and alkylated or (c) converted to aromatic hydrocarbons depending on the reaction conditions.  The reaction is suitably carried out in the presence of hydrogen.  The process may be used for the treatment of fractions containing a mixture of hydrocarbons and alkyl thiophenes such as the mixture of aromatic hydrocarbons and organic sulphur compounds obtained by the solvent extraction of distillation fractions of petroleum origin.  In the example, 2-methylthiophene, 3-methylthiophene, 2,5-dimethylthiophene and 2,3,5-trimethylthiophene are contacted with a catalyst consisting of alumina impregnated with hydrofluoric acid to give in each case mixtures of benzene, toluene, thiophene, methylthiophenes and dimethyl thiophenes.
