Title: Improvements in or relating to data transmission systems
Inventor: MISLAN JOSEPH DAVID
IPC: H04L27/26
Filed: 1963-11-19
Abstract: 1,003,500. Telegraphy. RADIO ELECTRONICS CORPORATION. Nov. 19, 1963, No. 45680/63. Heading H4P. The terminal stations of a data transmission system include a keyboard and a magnetic recorder for recording coded data received from the line or the keyboard. Frequency shift transmission is used. At the transmitter, Fig. 3, depression of a character key or function key at 14 sends a 7-bit parallel signal to store 304. A pulse also sets 16-bit counter 310, 318, 326 in operation whereby the tape in the recorder 28 is stepped first 4 bits, then 8 bits (during which recording takes place), and then another 4 bits. Store 304 is read out by counter 318, giving an 8-bit signal by addition of a Start bit. This signal includes a parity check bit and is recorded at 28, the complete message being subsequently transmitted at high speed at audio frequency over a telephone line. Certain functions, e.g. carriage return, may take longer to complete than the normal recording cycle of 16 bits. To prevent error from this cause, when these function keys are depressed the counter 310, 318, 326 caused to cycle more than once, so that more than 16 bits spaces are allotted to this signal. The function keys provide coded signals by way of a diode matrix. At the receiver, Fig. 4, the demodulated signals are recorded on magnetic tape at 28 and, when the complete message has been received, the data is read out at low speed. The serial signals are fed to a register 406 which provides a parallel output for controlling the printer. Correction of tape record prior to transmission. If the back-space key is operated simultaneously with a correction switch the tape in recorder 28 is stepped backwards by 16 bits and the data therein is erased. Parity check.-At the receiver the Start bit causes units 434, 436 to produce a clock signal which is added at 438 to the received data, resulting in the signal form shown. This signal is clipped and then operates a toggle-counter. The delayed Start bit samples the toggle at the end of the signal, any parity error being indicated at 456, and being counted.

Abstract: 1,213,897. Tobacco-smoke filters. H. F. & Ph. F. REEMTSMA. 27 Sept., 1968 [28 Sept., 1967], No. 45935/68. Heading A2C. [Also in Division B2] In an apparatus for producing combination filters for cigarettes, which filters comprise chambers filled with a flowable pulverulent filter material between two filter plugs, the pulverulent material is gravity fed into spaces opened up between consecutive sections of a column of fibre filter material and the resultant column of alternating pulverulent material and fibre sections is then sheathed and cut into lengths each containing one half of two consecutive fibre sections and an intervening chamber containing the pulverant material. In one embodiment, plug sections 25 and spacer elements 24 are severed by cutters 2, 7 from a continuous strand of fibre filter material 1 and a continuous plastics material 6 of star-shaped cross-section respectively, and are fed alternately by indexing turntables 3, 8 to positions above a funnel 9 into which they are pushed by a plunger 10. The plugs 10 and spacers 24 are then forwarded downwards by two sprung guided conveyer belts 11 to drop into a retaining shaft 13, a sensing contact 14 being provided to ensure the shaft 13 is kept full. Another sprung guided pair of conveyer belts 15 forwards the column of plugs 25 and spacers 24 down through a bore in a proportioning feed screw 18 that feeds pulverulent material 26 into the voids in the spacer elements 24 in a coned annular channel formed beneath it. The column of plugs 25 and pulverulent material filled spacers then passes on down through a mandrel 27 at the bottom of which a liquid plastics coating, fed by an extruding feed screw 32, is applied to sheath the emerging column. After the plastics sheath has set, the continuous sheathed composite filter rod is cut into individual composite filters. In another embodiment, no spacer elements are used. An unbroken column of plugs 25 descends between the belts 15 into a guiding sleeve (35) that lines the bore of the mandrel 27, and which sleeve (35) is reciprocated vertically to produce gaps between the plugs 25 as they leave the bottom of the mandrel 27, the gaps being filled with particulate material as they are formed.

Title: Improvements in the preparation of organophosphonic acids and their salts
Inventor: PECK DENNIS
IPC: C07F9/38
Filed: 1964-11-11
Abstract: Organophosphonic acids including those of the formulae CH3COPO(OH)2 CH3CO[CH3CO(PO3)2H4] and <FORM:1102525/C2/1> are obtained by reacting acetic acid with a phosphorus trihalide PX3, where X represents halogen, e.g. phosphorus trichloride, and employing at least 3.5 molar proportions of acetic acid per mole of phosphorus trihalide. The process may be carried out by heating the phosphorus trihalide with acetic acid, which may be glacial acetic acid or may contain a minor proportion of water (less than 10% by weight) or acetic anhydride, for at least an hour at a temperature above 80 DEG  C. Under such conditions the product separates into two layers with substantially all the phosphorus being contained in the lower layer. 1-Hydroxyethylidenediphosphonic acid (III) may be obtained by contacting the reaction mixture with water or steam preferably above 100 DEG  C., e.g. by steam stripping, heating to 110-120 DEG  C. to remove volatile impurities and recrystallizing, and salts of this acid may be obtained by contacting the reaction mixture with an aqueous suspension or solution of a base, e.g. sodium hydroxide, rubidium carbonate or ammonium hydroxide or with silver nitrate, calcium nitrate or cobaltous chloride. Acetoxyethylidene-diphosphonic acid (II) may be obtained by dissolving the lower layer of the reaction mixture in a hot non-aqueous solvent (e.g. glacial acetic acid) and allowing it to crystallize.  The invention also comprises the latter compound, which is believed to have the structure <FORM:1102525/C2/2> per se and it may also be obtained by reacting acetic acid with a phosphorus trihalide at a temperature below 50 DEG C. and recrystallizing the precipitate so formed from glacial acetic acid.

Abstract: 1489706 Desorption of methyl bromide from active carbon MITSUI TOATSU CHEMICALS Inc 12 Nov 1975 46639/75 Heading C2C [Also in Divisions B1 and Cl] A method for the desorption of methyl bromide from active carbon, e.g. used in treatment of fumigation waste gas, is characterized by feeding vapour of an organic solvent which is inactive or inert to methyl bromide, but which dissolves methyl bromide, either alone or in combination with water vapour or a gas which is inert to methyl bromide to the active carbon on which methyl bromide has been adsorbed, the temperature of the feed vapour or vapour mixture being such that the feed vapour or vapour mixture exists in a non-condensed state. The vapour which has passed through the active carbon may then be cooled to effect condensation, and the methyl bromide separated by distillation. The organic solvent may be a lower aliphatic alcohol or a chlorinated methane derivative, e.g. chloroform. The inert gas may be nitrogen, flue gas or air. The active carbon from which methyl bromide has been desorbed may be subjected to heat or hot air to drive organic solvent therefrom.
