Title: Frequency shift demodulators
IPC: H04L27/156
Filed: 1975-03-18
Abstract: 1482732 Data transmission; F.S.K. demodulators WESTERN ELECTRIC CO Inc 18 March 1975 [22 March 1974] 11107/75 Heading H4P An F.S.K. demodulator comprises a continuously running high speed counter reset by zero crossings of an incoming wave with a threshold further counter receiving counts between resets with a means supplying the threshold counter with counting rates proportional to each incoming frequency and an output to a plural state device responsive to each threshold count which selects a respective one of the counting rates, and determines the next threshold count level. The high speed counter may be resettable (a) in both transition directions and include a plurality of multistage counters or (b) in one direction and include a single multistage counter. The counters may be formed by multistage shift registers, and incoming data may be synchronous or asynchronous. Incoming signals through band limited channel 11 pass through a "squaring" limiter 12 to differentiator 13 which issues a chain of narrow pulses substantially at zero crossings, of received signals which control resetting of 8 stage counter A having provision for transferring the count to 8 stage B through AND gates 17A-17N (only two shown), the counters being stepped by a high speed clock 18 and may provide 96 counts per cycle at spacing frequency fs of 2200 Hz and 176 counts for marking frequency fm of 1200 Hz. After transfer, counter B continues counting until next zero crossing when content is transferred to counter C which thus receives sum of counts for two succeeding half cycles i.e. tends to perform an averaging function, which may be over a longer interval if desired. Alternatively counter A may count over a full cycle where responsive to zero crossings of one sense only. It is also envisaged that transfer may be performed serially. Counter C is then stepped at a rate proportional to either mark or space frequencies through dividers 22, 23 giving 96 (176) kHz outputs through AND gate 26 (27) and OR 24. Output of C is monitored by AND gates 28A, 28B whose inputs are connected to selected stages corresponding to mark and space thresholds, to OR 29 which resets C to a reference condition and bi-stable circuit 30 which provides data output, also controls AND gate 26, 27, together with exclusive OR gates 20A-20N which give a normal or complemented input to counter C which has mark (space) thresholds of 146 (172). During marking condition of incoming signals, crossing of the lower threshold value has no effect on circuit 30 which is already set; additionally an inhibit signal on lead 34 prevents operation of gate 28A hence prevents resetting of counter C through OR 29.

Title: Track signalling system
IPC: B61L17/02
Filed: 1934-04-14
Abstract: 441,455. Electric signalling systems. VEREINIGTE EISENBAHN - SIGNALWERKE GES., Siemensstadt, Berlin. April 14, 1934, No. 11330. Void [Abridged as open to inspection under Sect. 91 of the Acts, Oct. 26, 1934]. [Class 40 (i)] A signalling board for indicating to a pointsman the tracks into which successive trucks are to be shunted is arranged so that four numbers may be displayed at once, but the cancellation of the first does not take place automatically upon the transmission of a fifth but only as the result of some definite manual or automatic operation after the first has been dealt with. In the arrangement shown, on the closure of a contact G2 (corresponding to track 2) in combination with contact G0, relay A causes interrupter RU to advance switch DW1 to position 2 in which relay L operates and locks, and lamp 2 in the first indicating position is lit over wipers sw2 and dw13. Relay Z1 operates over wiper dw12. Three further indications may be similarly set up on switches DW2-DW4 which light corresponding lamps over wipers dw24, dw35, dw46, and a fifth may be stored on switch DW5. To cancel the first signal, the pointsman may operate key LT causing switch SW to advance one step so that wipers dw23, dw34, dw45, dw56 are connected up, the signals previously displayed in the second, third, and fourth positions are now transferred to the first, second, and third positions, respectively, and a fifth may appear in the fourth position. Relay W1 operates over wiper sw1 causing DW1 to advance to normal, when Z1 releases. Relay L1 is released by the operation of U5 if a fifth signal has been set up so that the next will pass to DW1. A locking magnet Sp for key LT may be controlled by relay B. Alternatively, switch SW may be advanced by a relay controlled from the track by the trucks passing over points. In a modified system requiring only a single line between the shunting master and the pointsman's cabin, step-by-step switches at the two stations operate in synchronism until that at the shunting end reaches the terminal corresponding to the operated contact (G1-G4), there being also at the cabin a distributing switch which successively connects the receiving switches (DW1-DW5) to the line. When a board is used in common for brakesmen and pointsmen, additional lamps controlled by a key may be provided for by the former to indicate the next operation. Additional signalling boards may be provided for brake-block attendants, such boards being switched on simultaneously with the main board or separately by hand or a vehicle, and switched off manually or by a vehicle or after a predetermined time.

Abstract: 359,465. Roughening yarns and threads. BRITISH CELANESE, Ltd., 22, Hanover Square, London. April 14, 1930, No. 11835. Convention date, April 13, 1929. Void [Published under Sect. 91 of the Acts]. [Class 120 (iii).] Filaments or yarns of artificial silk are roughened chemically, physically or mechanically so that staple lengths may be spun more readily, with or without other fibrous materials such as cotton, wool, natural silk or reconstituted cellulose. The filaments or yarns may be delustred in long lengths, e.g. hank form, or after stapling, in which case the lengths are preferably tied in bundles, placed in bags, and treated, e.g. with wet steam, hot water or aqueous solutions containing soap or other delustring salts at temperatures between 70‹ and 100‹ C. Mechanical roughening may be effected with abrasive material, preferably finely divided, such as kieselguhr, pumicestone, powdered glass, cardboard or emery, which may be mixed with oil or other liquid, either by drawing the filaments or yarns through the abrasive or by subjecting them to a stream of the abrasive with air or other fluid. In an example staple lengths of cellulose acetate filaments are tied in bundles, placed in bags, and immersed for 10 minutes in a bath containing 4 ozs. of neutral soap in 30 gallons of water for each 2 lb. of staples, at a temperature of approximately 100‹ C. In a further example, an additional ounce of soap and 4 ozs. of sodium carbonate is added to the same bath, the treatment in this case being effected in 1 hour at 78‹ C.

Title: Improvements in or relating to stiff or semi-stiff fabrics and articles
IPC: A41B3/10
Filed: 1943-07-21
Abstract: Stiff and semi-stiff laminated fabrics are produced by incorporating an organic ester of cellulose containing from about 1.5 to 2 acidyl radicles per C6H10O5 unit of cellulose into one or more layers of fabric in the absence of plasticizer or other solvent or softening agent and applying heat and pressure in the presence of water.  The esters of low acidyl value may be cellulose propionate, butyrate, aceto-propionate or aceto-butyrate, and especially cellulose acetate of acetyl value 40-45 per cent expressed as acetic acid.  The fabric may consist wholly of low acidyl cellulose ester yarn or it may be a mixed fabric containing such yarn in the warp or weft or both. Alternatively, the ester may be incorporated into non-thermoplastic fabric such as woven, knitted or netted cotton, linen, regenerated cellulose, wool or silk.  The ester may be applied in powder form with or without binders such as gum tragacanth or gum arabic or methyl cellulose that swells in water. The ester may also be applied to the fabric in solution in a volatile solvent, may be present as foil, or may be precipitated into the fabric.  Alternate layers of non-thermoplastic yarn and the ester containing material may be united and in all cases the assembly is wetted with water or steamed and subjected to heat and pressure.  Pigments such as titanium dioxide, antimony trioxide, carbon black or coloured pigments may be incorporated.  Embossed heating devices may be used to produce designs on the fabric, in which case unity of the fabrics occurs only at the places contacted.  The fabrics may be assembled and sewn on to an article of apparel, such as a shirt, wetted and subjected to heat and pressure in the final position.  Specifications 248,147, [Class 2 (ii)], and 568,047 are referred to.

Abstract: 1324159 Producing 7-amino-desacetoxycephalosporanic acid TOYO JOZO CO Ltd 14 March 1972 [31 May 1971] 11915/72 Heading C2A [Also in Division C3]  7 - Amino - desacetoxycephalosporanic acid having the formula is produced by N-deacylating a water-soluble salt of 7-phenylacetamido- or 7-phenoxyacetamido-desacetoxycephalosporanic acid with a deacylating enzyme produced by Bacillus megaterium B-400, FERM-P No. 748. The enzyme may be in the form of a culture filtrate of the micro-organism or a purified preparation derived from the filtrate, e.g. the enzyme adsorbed on a non-inactivating carrier (see Division C3). The preferred water-soluble salt of the cephalosporin is the Na or K salt, and the N-deacylation of the salt is effected either by incubating it insolution in a culture filtrate of the micro-organism or by passing its solution through a column of the enzyme adsorbed on an insoluble inert carrier, at pH 7-8 and 30-45‹ C. using a concentration of the salt of 0À1 to 20 mgs./ml. The 7-aminodesacetoxycephalosporin may be recovered by bringing the solution to its iso-electric point (pH 3.7), concentrating, cooling to precipitate the product and washing the precipitate with acetone and drying.
