Title: System for the transmission of information at very low signal- to-noise ratios
IPC: H04B14/04
Filed: 1971-07-22
Abstract: 1312550 Information transmission PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 22 July 1971 [25 July 1970] 34367/71 Heading G4H In a P.C.M. transmission system for very low signal-noise ratio transmission paths, a signal source 1 is sampled at 17 and P.C.M. coded at 18, the 3-bit code being converted at 20 to a 4-bit code which is read in via gates 19 to a 4- stage shift register 8 comprising stages 11-15, the register comprising an internal feed-back loop whereby the output of the last 2 stages 14-15 are combined at 16 in a binary adder and fed back to the first stage 11, this arrangement being such that under control of a clock 7, the register 8 moves through a periodically occurring set of 15 different binary states and an output 3 taken as input to stage 11 provides a cyclic pulse train of irregular alternation of the two binary values. This train is transmitted and received at 4 and fed to a binary combination circuit 27 for combination in binary adders 32, 33 with the outputs of second and third stages 13<SP>1</SP> and 14<SP>1</SP> of a corresponding pulse pattern generator 8<SP>1</SP>. The output of 27 is integrated at 28 and appiled to a controller 35 of a local clock 7<SP>1</SP>. In use, prior to sampling, a pulse pattern transmitted at 3 is received and processed at 27 and assuming the phase of the transmitted track is near to the phase of that produced at 8<SP>1</SP> a signal will be produced at 28 to modify the frequency of clock 71 to synchronize the two generators 8, 81. A frequency divider 21 is employed to provide sampling pulses and gating pulses at intervals of an integral number of periods of the pattern, and a binary code is formed at 20 and gated at 19 to the register elements 11-15. This reading in a P.C.M. word will cause an abrupt change in phase of the output pulse train. When this jump is received, the integrator 28 ceases to provide a signal and the clock 71 whose natural frequency is slightly greater than that of clock 7 causes the generator 8<SP>1</SP> to move through its states faster than that of the generator 8. When near coincidence is again reached, the integrator 28 causes exact alignment once more. The sampling pulses from 21 are transmitted via 26, 39 to be used to gate the output of code converter 36 to a P.C.M. decoder 30 to be reproduced at 6. In a modification, Figs. 3, 4 (not shown) the P.C.M. code is employed to provide a discrete number of clock pulses which change the phase of the generated train by a certain amount, the pulses being recovered in the receiver indicative of the coded amplitude. In a further modification, Figs. 5, 6 (not shown) a second pulse pattern generator is employed in both receiver and transmitter to provide the synchronized sampling pulses.

Filed: 1953-12-10
Abstract: 733,995. Separating fibres from non-fibrous materials. JOHNS-MANVILLE CORPORATION. Dec. 10, 1953 [Jan. 2, 1953], No. 34401/53. Class 117. [Also in Groups VIII and IX] In a process for opening and cleaning fibrous material, particularly mineral wool (see Group IX), non-fibrous material is separated from the fibres as a batch of material, deposited into a chamber 16 through a door 14, is suspended in a turbulent stream of gas moving upwardly from oscillating jets 20 and out through a door 24 covered with a filter bag 26. Non-fibrous material falls from the suspension through a screen 18. The amount of gas leaving jets 20 exceeds that escaping through door 24 so that pressure builds up in chamber 16. When a substantial pressure has been built up in chamber 16, a time-controlled mechanism 38 shuts door 24 and opens a fibre outlet trunk 28 ; the release of pressure discharges the fibre suspension rapidly through trunk 28.

Title: Method of forming enclosures, for example aircraft canopies from thermoplastic sheet material
IPC: B29C65/00
Filed: 1953-12-15
Abstract: 747,362. Making aeroplane canopies &c. from thermoplastic sheet material. GOODYEAR AIRCRAFT CORPORATION. Dec. 15, 1953 [June 12, 1953], No. 34875/53. Class 87(2) A transparent, oblong, multi-curved enclosure of substantially half-round crosssection, e.g. an aeroplane canopy, is made by stretching a heated transparent thermoplastic tube equally in both longitudinal and circumferential directions to reduce the thickness of the tube wall to about one quarter of its original thickness, engaging the edges of the stretched tube with contour members, cooling the tube and slitting or rimming it along the path of engagement of the tube with the contour members. A single canopy may be formed by trimming away half the tube, or two canopies may be formed face to face and slit apart. A hot tube W, Fig. 2, is clamped at its ends by clamps 11 to shafts 6, 9 and is stretched longitudinally by pulling shaft 9 to the right by means of an electric motor and cable. The shaft 9 slides in bearings 7, 8 on a standard 4 and its tube-clamping end is supported in a carriage 22, 23 that runs on hollow rails 20. The ends of the tube are cooled by water passing through rails 20, pipes 25, 26 and hollow clamping plugs 10. The clamps 11 are spring-pressed to operative position, and the left-hand clamp may be released by a manually-operated cam lever 18. After longitudinal stretching the tube is expanded by fluid pressure introduced thereinto through (hollow) shaft 6, the tube being expanded to the shape W<2>. Fig. 6, against a jig 34 secured by clamps 35 to the rails 20. The tube may be thus stretched 100 per cent both longitudinally and circumferentially,. Prior to longitudinal stretching the ends of the tube may be expanded by a mandrel. The degree of stretch longitudinally or circumferentially may be controlled by local heating or cooling of the tube. The circumferential stretching may be effected not by fluid pressure against a jig, as above, but by radial expansion into a rigid mould or by centrifugal forming with or without a jig.

Title: Water soluble polymerizable mixed ethers of cellulose
IPC: C08B11/193
Filed: 1959-10-16
Abstract: Water-soluble, polmerizable, cellulose mixed ethers are made by reacting cellulose in the presence of alkali simultaneously or in either order with a mono-halogen acetic acid or a watersoluble salt thereof and an allyl halide at a temperature below 110 DEG C. Cellulose may be reacted in the presence of alkali with a mono-halogen acetic acid or an alkali-metal salt thereof to obtain cellulose glycollic acid, which is then treated with the allyl halide.  Both reactions may, alternatively, be performed simultaneously.  In a preferred method, cellulose glycollic acid with an average degree of substitution of 0,2-1,0 is reacted, either (a) in the presence of excess sodium hydroxide solution with an allyl halide, preferably also present in excess, at a temperature of 75 DEG -110 DEG C., preferably 75 DEG -90 DEG C., or (b) in the presence of sodium hydroxide solution not in excess with excess of an allyl halide at a temperature below 75 DEG C.  Etherification of the cellulose may be effected by mixing the reactants at elevated temperatures, solvents being present if desired.  Specified solvents include hydrocarbons, chlorinated hydrocarbons with at least two chlorine atoms, alcohols with three to five carbon atoms, and alkyl ethers.  The cellulose allyl glycollic acid ethers so made desirably contain 0,2-1,0 mols. of glycollic acid and about 0,3 to about 0,6 mols. of allyl groups, per glucose unit.  The ether products, and their water-soluble salts, can be polymerized in the presence of catalysts to form water-soluble products, provided they contain about 0,1 mol. or more of allyl groups per glucose unit.  In an Example (1), an aqueous solution of such a product is caused to gelatinize by the addition of about 2-5% by weight, based on the cellulose ether, of a redox catalyst, suitably a mixture of potassium persulphate and sodium sulphite.
