Title: Nonhierarchical telecommunications networks
IPC: H04L12/00
Filed: 1973-04-25
Abstract: 1409154 Automatic exchange systems SIEMENS AG 25 April 1973 [25 April 1972] 19776/73 Heading H4K In a non-hierarchical exchange system in which a route between a calling and a called party is hunted by passing the called number message from exchange to exchange and keeping a record of the route portions traversed by the message either in each tandem exchange or with the message itself, an indication of the quality route demanded by a particular connection, e.g. a data call, accompanies the message and is amended at each tandem exchange in dependence on the actual conditions encountered on the trunks incoming to the exchanges. As shown, a caller 123 who requires a data connection of quality code 6, causes this code to be added to the destination address 456 of the wanted party. The code may be transmitted directly by the caller or it may comprise part of his class of service information at his home exchange 1. At exchange A, a central control determines the non-attachment thereto of party 456 and so forwards an amended hunting message 456-5 to adjacent exchanges B, D. The digits 1, 2, 2 at the incoming sides of exchanges A, B, D respectively, denote the "quality loss" on their incoming trunks. These digits are subtracted from any quality code passing therethrough. If the code eventually becomes zero (or negative) as happens at exchange G the hunting message is not passed on any further. If similar codes enter an exchange, e.g. 456-3 into exchange E, only that resultant code from the higher quality incoming trunk, e.g. from D, is passed, the other one being suppressed. (It will be remembered that each hunting message involves routealready-traversed information and it is really this information that is being suppressed in the two examples just given.) Where equal quality codes are involved as in exchange F, the routing information for both incoming paths is maintained. If a later-arriving code denotes higher quality than an already passed code, the former's routing information is adopted (where possible) in place of the latter's. At the terminal exchange, an acknowledge code is sent back through the network so that the chosen route can be set up. The acknowledge code includes quality information which may be assessed by the participating stations as requiring for instance a lower, e.g. 600 bit/s transmission rate than usual, e.g. 1200 bits. Transmission may be effected over line or radio using space, frequency, time or sequency multiplex techniques using PCM where appropriate.

Filed: 1920-07-09
Abstract: 147,829. Ray, W. R. May 8, 1916, [Convention date]. Spray burners; burners, attaching and mounting. - In an oil burner, an electric motor 11 is provided with a hollow shaft 12 on which is mounted a fan 13 and atomizing-cup 14. In operation the fan draws air through an inlet 15 in a cover 7, and delivers the air through a chamber 16 to a nozzle 17, which encloses the atomizing-cup 14 and has guide vanes 17<a> to prevent rotary movement of the air current. The oil is delivered from a stationary pipe 21 in the hollow shaft 12 to the cup 14, and is sprayed therefrom by centrifugal force into the surrounding air-current, which projects it into the furnace. An oil pump 23 driven at reduced speed off the main shaft discharges the oil through a valve 22 into the oil pipe 21, surplus oil being by-passed to the main oil supply. The burner structure is mounted on hinges 5, 9 on the front plate 3 of the furnace and may swing round clear of the opening 2.
Patent GB-614056-A (GB)
Title: Improvements in and relating to the removal of water from organic compounds by distillation
IPC: B01D3/36
Filed: 1946-07-03
Abstract: Organic compounds, including those which form azeotropes with water, are dehydrated by distilling the aqueous compound in the presence of furan or a mono-alkylated furan such as 2-methyl or 2-ethyl furan. The added substance forms a binary azeotrope with water, or in certain cases a ternary azeotrope with the organic compound and water, which separates on condensation into a water-rich layer and a solvent-rich layer; the latter may be returned to the distillation zone.  In an example, 200 mols. of ethanol containing 5 per cent of water, and 100 mols. of 2-methyl furan were boiled in a still connected by a packed column (2 feet long) to a condenser and decanter.  The vapours were condensed and decanted, the upper layer being returned to the column.  After 12 hours, all the water had been collected in the decanter; the liquid in the still was then fractionated to give first 2-methyl furan, then ethanol; the latter contained only 0.1 per cent water and 0.27 per cent 2-methyl furan. On a large scale, the aqueous layer would be treated in an auxiliary still from which an overhead fraction containing water, ethanol and 2-methyl furan would be taken off and returned to the main still, while water would be rejected from the bottom of the auxiliary still. Other examples describe the dehydration of acetonitrile, propionic acid, secondary butanol, and tetrahydrofuran.  Reference is also made to the removal of water from isopropanol, from sorbitol, and from esterification reactions.

Title: Polyisocyanate modified linear polyethers
Inventor: TIMSON JOHN ALBERT
IPC: C08G18/48
Filed: 1952-08-11
Abstract: The linear polyethers claimed in the parent Specification obtained by reacting substantially equimolecular proportions of a dihydric phenol and a disulphonic ester of a diol in presence of an amount of alkali which is at least twice the molecular proportion of the disulphonic ester are reacted with an organic polyisocyanate whereby their molecular weights are increased.  A non-fibre forming polymer may thus be made fibre forming. Reaction is effected at 170-220 DEG  C. under an inert gas.  The polyisocyanate may be added in an inert solvent which evaporates at the reaction temperature used.  Specified polyisocyanates are hexamethylene-, 2.4-tolylene- and 2.6-tolylene-diisocyanates.  In examples in which the reaction between the polyether and diisocyanate was effected at 179 DEG  C. in a nitrogen atmosphere and the product was washed with alcohol and dried: (1) Diethylene glycol-di-p-toluene sulphonate, hydroquinone and caustic soda were heated under reflux in dioxane and water and the precipitated polyether was boiled first with water, then with hydrochloric acid and finally with water.  The polyether was then reacted with hexamethylene diisocyanate.  (3)-(8) The polyether of example (1) was mixed with hexamethylene diisocyanate dissolved in acetone and the mixture reacted.  (2) Pentane-1.5-diol-di-p-toluene sulphonate was reacted with hydroquinone as in example (1) to form a polyether which was reacted with hexamethylene diisocyanate. (9)-(11) The polyether of example (2) was mixed with hexamethylene diisocyanate dissolved in benzene and the mixture reacted.
