Patent GB-122179-A (GB)
Title: Improved Process of and Means for the Manufacture of Gas or Gases.
Inventor: BROADHEAD CHARLES FREDERICK
IPC: C10J3/00
Filed: 1919-01-02
Abstract: 122,179. Broadhead, C. F. Jan. 7, 1918, [Convention date]. Retorts, method's of working.-In the manufacture of mixed coal gas and water gas, a vertical retort D is surrounded by checker brickwork J, and the whole contained in a shell A. At the bottom is a grate F and during the air blow the gas valve P is closed and the hot gases pass around the retort D, air being admitted at H to complete the combustion thereof, the waste gases being discharged through a snift valve N. Any coal gas and vapours so produced are discharged through a by-pass Q. During the run, steam is admitted through a pipe R and the valve P is opened and the valve N closed. In starting, coke is introduced through a door M and blown to incandescence. Between each subsequent steam run, coal is introduced to the desired level through the gas-tight coal valve L.

Title: Improvements relating to voice transmission systems
IPC: G10L25/00
Filed: 1956-01-02
Abstract: 806,924. Secret transmission. COMPAGNIE FRANCAISE THOMSON-HOUSTON. Jan. 2, 1956 [Jan. 7, 1955], No. 60/56. Drawings to Specification. Class 40 (4). Speech is transmitted by transmitting two variables only, viz. the instantaneous frequency and the instantaneous value of the amplitude envelope. It is stated that since both these variables vary at syllabic frequency they may be transmitted over channels having limited bandwidth, e.g. 25 c.p.s. As described the speech signals are fed to a detector producing a signal proportional to the amplitude of the signal, the time constant of the circuit being so large that the output follows only the syllabic variations. The speech currents are also fed, either directly or after transposition to a higher frequency band, to a limiter whose output feeds a frequency discriminator whose output circuit has a similarly high time constant. The two outputs may be multiplexed in any suitable way for transmission on a single line. The limiter may be of the type using rectified feedback, the feedback signal then being taken as a measure of the amplitude. At the receiver is provided an oscillator having its frequency and amplitude respectively controlled by the two signals.

Title: Pre-mixing device for gas turbine combustion apparatus
Inventor: OTSUKA MASAYA
IPC: F23R3/30
Filed: 1996-01-04
Abstract: PROBLEM TO BE SOLVED: To enable a flow speed distribution to be uniformly attained at an outlet of a pre-mixing device with a short length of the pre-mixing device by a method wherein either a porous plate or a grid plate is installed inside a straight pipe. SOLUTION: Air 7 flows through a flowing-in section 8 formed by an outer cylinder 1, an inner cylinder 2 and a partition plate 3, through a bent pipe section 9 and a straight pipe section 10, passes through an outlet 11 of a pre- mixing device and flows into a combustion chamber 12. Fuel 13 passes from a fuel reservoir 14 through a fuel nozzle 6 and is mixed with air 7 in the bent pipe section 9. In this case, an eccentric flow generated at the bent section 9 is regulated by a porous plate 14 installed at a downstream side of the bent section 9 and then a flow speed distribution at an inlet port of the combustion device can be made uniform with a length of the short pre-mixing device. Due to this fact, it is possible to restrict a blowing-off flying of the flame or back- fire, and to restrict combustion vibration by changing a length of the pre-mixing device.

Abstract: 322,375. Simon-Carves, Ltd., and Ashton, E. Jan. 4, 1929. Addition to 267,662. Tipping - apparatus. - Relates to that form of the apparatus described in the parent. Specification in which separate ropes are secured to each winding drum, one rope for hoisting and lowering each of the two tipplers, sufficient spare coils of each rope being wound on the drum for paying- out during a complete lift by the other rope. To reduce by one half the amount of spare rope required, each rope is secured to the barrel in a groove 21 or 22 so that whilst one tippler is being lifted the spare rope for the other tippler is first payed out from the central portion 15 of the drum and then wound on the outer portion 16 or 17. In this way the rise and fall of the taking-up pulleys is also reduced by one-half and guides for these pulleys are unnecessary. As shown in Fig. 3, a pair of pulleys 9, 9<a> aremounted on a frame 24 and hang in bights of the rope 13 which passes over pulleys 6, 6a at opposite sides of the tippler A. The ends of the rope 13 are secured to separate drums driven simultaneously for hoisting or lowering the tippler.

Abstract: 656,364. Photographic diazotype material. GENERAL ANILINE & FILM CORPORATION. Jan. 7, 1949, No. 522. Convention date, Jan. 20, 1948. [Class 98 (ii)] An azo coupling component for incorporation in photographic diazotype material or in an alkaline developing solution therefor is a carbonic ester of resorcinol, which may be obtained by reacting resorcinol with phosgene in the presence of a base such as pyridine, dimethylaniline, or quinoline. The resorcinol carbonate may be di-resorcyl carbonate or a polymeric resorcinol carbonate. Two-component material containing a resorcinol carbonate as coupling component is stable to precoupling. The coupling component may be incorporated in the sensitizing composition or applied separately either in a separate solution or by rubbing it in powdered form on the surface of the support, which may be paper, transparentized paper, regenerated cellulose, or a cellulose ether or ester. Numerous diazo compounds are specified. In example 1, transparentized paper is coated with an aqueous solution of a resorcinol carbonate (prepared by reaction of 1 mol. of resorcinol with 1 mol. of phosgene), N - (21 - hydroxyethyl) : N - methylaniline - p - diazonium chloride zinc chloride double salt, isopropanol, ethylene glycol, citric acid, thiourea, and saponin. The exposed material is developed with ammonia vapour. In example 2, the procedure is similar using a resorcinol carbonate prepared by reaction of 2 mols. of resorcinol with 1 mol. of phosgene. In example 3, transparentized paper is sensitized with an aqueous solution of N-ethylaniline - p - diazonium chloride - zinc chloride double salt or N : N-diethylaniline-p-diazonium chloride-zinc chloride double salt, a resorcinol carbonate as in example 1, citric acid, phosphoric acid, isopropanol, and thiourea. In example 4, the procedure is similar to example 2, using the zinc chloride double salt of N-ethylo-toluidine-p-diazonium chloride. Ammonia development may be replaced by wet or semiwet development with a solution of an alkali metal carbonate or tertiary phosphate, and one-component material may be developed with a similar solution containing the coupler.
