Title: Time-division multiplex data transmission
IPC: H04L25/06
Filed: 1973-01-04
Abstract: 1421241 Data transmission systems DATABIT Inc 4 Jan 1973 [6 Jan 1972 (3)] 596/73 Heading H4P A system for receiving data signals, including Telex signals, having two polarities, comprises: means for sampling the signals at predetermined intervals after receiving a signal having a first polarity representing a free line state, the sampling taking place after a lapse of time less than the interval between sampling pulses; means for inverting the polarity of the signals during a free line state; and means for restoring the polarity in response to a signal of predetermined length, whereby sampling is initiated by a transition in an inverted signal from the freeline polarity to the other and a Telex call signal having a length less than the sampling interval but greater than the time lapse is not missed. In an arrangement for time division multiplexing a 50 baud channel applied to interface 38, with a 75 baud channel applied to interface 40, clock signals are applied from time base 41 to the two interfaces, which are so programmed that the 50 baud data is sampled at a basic rate, and the 75 baud data is sampled at twice the basic rate. The sampled data and a " class of traffic " signal, indicative of which channel is being sampled, are fed to a synthesizer 42 which includes coding cards corresponding to the two baud speeds. The " class of traffic " signal selects an appropriate card, which causes a counter to count the samples, and generate a sampling pulse at the centre of the bit which is being sampled. This sample pulse is then stretched and fed to a bit counter 44 which contains further code cards corresponding to the two baud speeds. This counts the bits to determine the end of a character and, in the case of the 75 baud data, adds pulses after the second and fifth bits to convert it to 100 baud. The synthesizer 42 and counter 44 are coupled with a memory 50 and register 48 to regenerate the pulses and arrange them in the correct time slots. The data is then passed to the unit 59 which forms the frames and adds the synchronizing pulses. In order to accommodate calling pulses which are shorter than the normal data pulses, the bit counter 44 includes a unit which causes the synthesizer 42 to operate in the " invert " mode by time displacing the sampling pulses and shortening the bit counting period, which detects the end of a character, from seven bits to four. In this mode gates 92, 94 of the synthesizer, Fig. 4, from an alternative path for the signals IDB. The gates 96, 98 unlatch the adder stages A 0  ... A 5  after they receive their input.

Abstract: <PICT:0792648/III/1> An acidic aqueous emulsion of a bituminous binder is prepared by agitating the binder with acidified water in the presence of a minor proportion of a nitrogenous compound selected from (a) primary, secondary, and tertiary aliphatic monoamines having less than 13 carbon atoms in the molecule; (b) primary, secondary, and tertiary aliphatic polyamines; (c) monocarboxylic acid salts of amines of (a) and (b); and (d) amido-amines and amido-amine salts. The amount of nitrogenous compound may be 0.01-2 per cent, preferably 0.1-0.5 per cent, by weight of the binder. Hydrochloric, acetic, or formic acid, in amount of 0.1-1 per cent by weight of the emulsion, may be used to acidify the water.  The preferred pH of the final emulsion is between 0.5 and 4.  In Examples (I)-(V) bitumen is mixed in a centrifugal pump with an aqueous solution containing hydrochloric acid and dodecylamine, octadecyl - 1 - amino - 3 - propane, 1 - (octadecylamino) - 3 - (31 - aminopropylamino) - propane, oleylamidoethanamine, or oleylamidodiethyl-ethanamine.  A minor proportion of a cut-back solvent and/or an anthracene oil may be added to the emulsion.  Using the apparatus shown, bitumen is heated in vessel A and water is mixed in vessel B with acid, the amine emulsifying agent and if desired a solution of gelatine or casein, circulation taking place via valves 4, 8 and pump 6.  Valve 8 is then closed and valves 3, 9 opened, bitumen being injected into the aqueous phase and the mixture passing to vessel C where it may circulate via valve 5.  When vessel A is empty, a mixture of cut-back and anthracene oil may be placed in the vessel and injected in the same way as the bitumen.  Finished emulsion is withdrawn at 10. Examples (VI) and (VII) employ this method, dodecylamine hydrochloride being used as the emulsifying agent.  The emulsions may be used for the formation of roads or boards, and may be applied to flint, quartzite or silica.ALSO:Aggregates are treated with an acidic aqueous emulsion of a bituminous binder which has been prepared by agitating the binder with acidified water in the presence of a minor proportion of a nitrogenous compound selected from (a) primary, secondary, or tertiary aliphatic monoamines having less than 13 carbon atoms in the molecule, (b) primary, secondary, and tertiary aliphatic polyamines, (c) monocarboxylic acid salts of amines of (a) and (b), and (d) amido-amines and amido-amine salts (see Group III).

Abstract: 776,532. Thermal regenerators. BEAVIS M. C. HARTNELL-. April 13, 1954 [Jan. 13, 1953, Feb. 23, 1953, Nov. 25, 19531, Nos. 985/53, 4944/53 and 10834/54. Divided out of 776,533. Class 64(1) Heat transfer material is mounted within a matrix flow passage of a thermal regenerator by supporting means which extends from a terminal end face or faces of the matrix and defines a flow path for one or other of the heat exchanging fluids such that hot fluid and heated fluid do not impinge on the passage walls in passing through the matrix. Fig. 4 shows an arrangement at the high pressure side of a rotary matrix type counterflow thermal regenerator, in which the matrix flow passages are defined by partition walls extending radially between inner and outer conical rotor sections 25, 27. The heat transfer material in each passage is in the form of blocks 31, 34 carried by supports 30, 33 respectively, the supports being secured to the matrix at the "hot" end thereof. Initially cold high pressure fluid enters the matrix at inlet 23a and on passing through the heat transfer material 31, 34 and becoming heated, is thereafter prevented from impinging on the walls (e.g. 25) of the matrix passages by the supports 33 which also prevent low pressure heating gas entering the matrix through an inlet 24 from impinging on the matrix passage walls before flowing through the heattransfer material 31, 34 and becoming cooled. The arrangement shown is such that some of this cooled low pressure fluid is permitted to circulate between the matrix outer section 27 and a stationary casing 20 and also within the inner section 25 and between the support 33 and the section 25 to maintain the whole matrix at or about the same temperature to minimize distortion. Alternative dispositions of the blocks of heat transfer material in the matrix flow passages are described and the provision of baffles in the said passages is mentioned. The edges of some of the blocks of heat transfer material may be located behind circumferential sealing flanges of the matrix such as flange 29. Fig. 5 shows a further form in which the "hot" terminal face of the matrix is protected by a plate 50 secured thereto in a manner which permits relative thermal expansion between these parts. Such a plate may itself constitute the circumferential and sealing flanges of the matrix at one or both terminal faces thereof and the end plate at the "hot" end of the matrix may carry the filler block supports. Sealing arrangements as described in Specification 776,533 may be incorporated. Specification 750,303 also is referred to in the Provisional Specification.
