Title: Improvements in and relating to solid-fuel combustion appliances
Inventor: BURKE SHULDHAM ARCHIBALD
IPC: F23L1/02
Filed: 1958-03-04
Abstract: 884,131. Boiler furnaces. C.U.R.A. PATENTS Ltd. April 21, 1959 [March 4, 1958], No. 6972/58. Class 51 (1). A method of operating a solid-fuel furnace having a moving grate comprises detecting variations in the temperature of a body situated within a region over the rear end of the fuel-supporting part of the grate and varying the total rate of supply of primary air and/or the distribution of the primary air along the length of the fuel-supporting part of the grate in accordance with the variations. Apparatus for carrying out the invention in a solid fuel boiler furnace having a chain grate 1 comprises pivoted dampers 16, 17, 18 mounted in partitions 6, 7, 8 of an air chamber beneath the grate for regulating both the total rate of supply of primary air to the grate and the distribution of the supply over the length of the fuel-supporting portion of the grate. A piston-rod 21 operated by a bellows (not shown) in a vessel 28 controls the dampers and is responsive to the temperature of air within a U-tube 34 situated within a region over the rear end of the grate and effective upon an increase in the temperature to open the dampers successively from front to rear and also increase the degree of opening of any of the dampers already open so as to allow primary air to the grate progressively towards the rear of the grate and an increase in the temperature to decrease the degree of opening of any damper already open and to close the dampers successively from rear to front. From the outlet side of a fan (not shown) which supplies through a conduit 32 to the air chamber a tube 33 leads through the chamber and the partitions to the U-tube 34 and thence by a tube 35 back through the chamber beneath the tube 33 to a port in the chamber which gives access to a hollow member 31 and by a tube 36 to the inlet side of the fan. Thus, when the fan operates the pressure difference across it causes air to flow through pipes 32 to 36. When the air in the U-tube is heated and passes to a member 31 it heats a phial 30 therein which is part of a closed system comprising the space between the bellows and vessel 28, a tube 29 and the phial. Liquid in the system expands to compress the bellows and thereby moving the rod rearwardly to operate the dampers. An increase in the rate of fuel supply, which is determined by the water temperature, automatically increases the rate of air supply and the length of grate which is operated since the fuel bed approaches the U-tube with consequential greater heat thereto which automatically opens the dampers. Secondary air is supplied over the front portion of the grate by means (not shown) which comprises a duct from the fan having a valve which is controlled by additional temperature-responsive means connected to the U-tube. In a modification, the bellows vessel 28, tube 29 and phial 30 may be replaced by a bi-metallic element operated by the action of heat from the tube 35.

Title: Improvements in or relating to reinforced plastics
Inventor: MORRIS DAVID RICHARD
IPC: B29C70/52
Filed: 1964-02-19
Abstract: Reinforced plastics articles are produced by passing a reinforcing material e.g. a glass fibre mat, through a sub-atmospheric pressure zone to a bath of liquid, heat-hardenable, resin, the impregnated material is then passed through a heated die to solidify the resin. Preferably, the reinforcing material 11 enters a chamber 14, at sub-atmospheric pressure, through a pressure sealing gland 13, passes over a roller 22 into a bath 23 of resin, Fig. 1.  The material 11 is guided up through a chamber of a tower 24, which is divided into two vertical chambers by a partition 32, the two chambers communicating at the top by way of a chamber 25 at a sub-atmospheric pressure less than that in the chamber 14, thus maintaining a column of resin in the tower 24.  The impregnated reinforcing material then passes down through a second resin bath 31, in the other chamber of the tower 24, to a die 34.  The inlet end of the die is tapered, to facilitate entry of the material, and cooled by means of passages 36, to prevent solidification of the resin in the entry.  The central portion of the die is heated as by electric elements 37, the outlet end being cooled by passages 38.  After leaving the die, the extruded article passes through a chamber 40, at sub-atmospheric pressure, to a pressure sealing gland 42.  The heat-hardenable resin may be an epoxy or polyester resin.

Abstract: 837,172. X-ray responsive electroluminescent screens. WESTINGHOUSE ELECTRIC CORPORATION. March 5, 1958 [March 13, 1957], No. 7051/58. Class 39(1). The contrast in the luminous response to an X-ray signal of a phosphor screen displaying an enhanced electroluminescent output when irradiated by X-rays and simultaneously excited by an alternating electric field is varied by the following steps:-passing X-rays of selected intensity through a stationary object having varying X-ray permeability to generate a first X-ray signal which is applied to the screen together wtih an alternating electric field to effect a phosphor-screen presentisization varying in degree according to the quantity of X-rays applied thereto, removing the applied X-ray signal and the applied field, repassing X-rays of preselected intensity through the object to generate a second signal, and applying this signal to the screen to produce thereon a transient luminous object image varying in luminosity with the varying X-ray intensity of the second X-ray signal and with the degree of screen presensitization previously effected whereby the contrast between individual portions of the transient object image formed on the screen is varied. The applied first X-ray signal may be removed before or simultaneously with the applied electric field. In the example recited the brightness of a portion of the screen receiving through the object first X-ray irradiation of 160 ÁA per minute and an applied electric field is shown as O-T-U, Fig. 5 and, for the screen portions adjacent the more X-ray opaque portion of the object with an irradiation of 80ÁA per minute the brightness is shown as O T<SP>1</SP> U<SP>1</SP>. The first X-ray signal and the applied field are removed and after a quiescent time of about one minute, the second X-ray irradiation is applied to the presensitized screen. The brightness curves of the " high " and " low " spots after this irradiation are hsown as OXY and OX<SP>1</SP>Y<SP>1</SP>, the contract ratio to the peaks X, X<SP>1</SP> being greater than that in the presensitization image. The contrast ratio may be lowered by using lower X-ray strengths in the second irradiation. The phosphor screen construction is of the kind described in Specification 772,572. The electroluminescent material may be mixtures of zinc and cadmium sulphide wherein the ratio of Zn to Cd is from 9 : 1 to 3 : 7 activated by from 0À01 x 10-<SP>2</SP> to 6À0 x 10-<SP>2</SP> mole of manganese. Silver may also be present from a mere trace up to 1À0 x 10<SP>-2</SP> mole Ag per mole Mn. Specification 837,171 also is referred to.

Title: Improved process for the manufacture of linear synthetic polymer yarns
IPC: D01F6/60
Filed: 1953-03-13
Abstract: <PICT:0730501/IV (a)/1> In order to obtain a package of yarn of a synthetic linear polyamide having a predetermined final tenacity and a predetermined final breaking elongation measured on the yarn as it is unwound from the package, a polyamide yarn is subjected to cold-drawing at substantially room temperature between a cold low-speed advancing device and a high-speed advancing device a p part at least of which is heated to a temperature substantially comprised between 80 DEG  and 40 DEG  C. below the melting point of the polyamide, the drawing ratio, defined by the ratio of the linear speeds of the two advancing devices, being only slightly higher than the drawing ratio corresponding to the final tenacity and breaking elongation after packaging.  The polyamide may be that obtained by polycondensation of amino-caproic acid.  As shown, the yarn is cold drawn as it passes between the two roller systems 11, 12.  The main roller 14, or both rollers, of the system 12 is heated, e.g. by means of electrical resistances, to a temperature which, in the case of a polyamide from amino-caproic acid, may be 170 DEG  C.  If a 30 denier, 10 filament yarn of a final tenacity of 4.5 grams per denier and a breaking elongation of 20 per cent, corresponding to a final drawing ratio of 380 per cent, is required, the actual drawing ratio imparted by the roller systems 11, 12 should be made slightly higher than 380 per cent, e.g. 383 per cent, the excess being adjusted according to the nature of the polyamide, the characteristics of the yarn, the temperature of the hot roller and the number of times the yarn is wrapped about that roller.  Instead of the roller systems 11, 12, systems of thread-advancing cages, arranged eccentrically or askew or interdigitating with respect to one another, may be provided for stretching the yarn.

Filed: 1950-03-22
Abstract: 669,723. Tyre valves. MASSAT, A. E. L. March 22, 1950, No. 7135/50. Class 135 [Also in Group XXVIII] A tyre valve having means for automatically admitting additional air into the inner tube to compensate for losses comprises a member 1 divided into upper and lower chambers a, b by a piston 5 urged by a spring 19 away from the inner tube 4 and connected by a flexible, non-extensible cable 16 to a point on the inner tube diametrically opposite a threaded sleeve 2 to which the member is connected. The piston 5 has an opening in its upper end 6 controlled by a spring-loaded check valve 7, and screw-threaded members 11, 12, 13, at its lower end to adjusting its position relative to the member 1, the loading of the spring 19 and the tension in the cable 16. The member 1 has a spring-loaded, pressure relief valve 30, an oiler 36, and an inlet chamber 25 having an air filter 27 and communicating through a spring-loaded check valve 21 with the chamber a. The tube is inflated in the usual way through a hollow stem 29 and the check valves 21, 7, to a predetermined pressure. During the running of the vehicle, should the pressure in the tube fall below the desired value, the tyre will on revolution of the wheel be alternately deflated and expanded. On deflation of the tyre, the cable 16 will slacken to permit the spring.19 to urge the piston 5 upwards, whereupon the air in the chamber a is compressed and the valve 7 opened to admit additional air to the tube 4. On expansion of the tyre, the cable 16 pulls the piston 5 downwards whereupon the pressure in the chamber a decreases and the valve 21 opens to admit atmospheric air to the chamber a, which on the next cycle of operations is compressed and transferred to the tube until the pressure therein is restored to its desired value. Should the pressure in the tube rise above its desired value through, e.g. increase in temperature, the excess pressure will be relieved by the valve 30.

IPC: C25B3/23
Filed: 1965-02-19
Abstract: Organic isocyanates, urethanes or ureas are produced in an electrolytic cell by electrolyzing a solution free from interfering anions and comprising: an ionizable cyanate or isocyanate, e.g. of an alkali or alkaline earth metal or a lower tetra-alkyl ammonium ion having at most 20 C atoms; and at least one of those aromatic compounds containing at least one replaceable H atom, e.g. benzene or naphthalene or a mono or dialkyl derivative thereof, thiophene, pyrole, furan or ferrocene, and/or the olefinic compounds, e.g. an olefine having 2 - 8 C atoms or a diolefine having 4 or 5 C atoms; and, when a urethane, an alcohol or phenol, or, when a urea is desired, a primary or secondary amine.  Preferably a stable solvent, e.g. an ether, a nitrile or nitro-methane, is present at the anode. The organic isocyanate may be recovered by cracking the urethane or urea formed.  To prevent organic isocyanate from contacting the cathode, the cell is preferably divided into anode and cathode compartments by an anion selective membrane, e.g. an anion exchange resin of the quaternary ammonium type; the above solution is then the anolyte, and the catholyte may comprise urea and a phenol or alcohol and a cyanate or isocyanate of an alkali or alkaline earth metal and/or Al. In the anolyte, isocyanates of Al, B, Fe, Ag, Cd, Au or Pt group metals may be used.  Preferably a Pt anode and Ag gauze cathode are used, and the catholyte is stirred by a stream of argon.
