Title: Fire-proofing of bonded cellulosic and lignocellulosic articles
IPC: C08L61/06
Filed: 1966-05-19
Abstract: A fire-resistant bonded, coated or sized cellulosic article, e.g. chip-board, plywood, paper, cardboard, or laminated paper, is made by including in the aqueous bonding coating or sizing composition at least two substances being inorganic bromides or oxybromides, at least one being a bromide.  One of the two substances lowers at least one fluid state characteristic, i.e. viscosity or surface tension, of the bonding composition, and the other one raises the same characteristic, the quantities of the substances being such as to impart the required degree of fire-resistance and to adjust the fluid state characteristic to a preferred value.  The weight of the substances may be 0.4-12% of the cellulosic material.  Exemplified bromides are those of Na, K, NH4, Ca, Mg, Zn, Co, Pb, Sb and Fe and oxybromides, those of Ca and Mg. Present may be other inorganic substances, e.g. borax, boric acid, phophates, antimony oxide, sulphamates, and ammonium sulphate.  Bonding agents may be e.g. starch, phenol-formaldehyde, urea-formaldehyde, melamine formaldehyde, sodium silicate, and proteinaceous adhesives, alone or in admixture.ALSO:A fire-resistant bonded, coated or sized cellulosic article, e.g. chip-board, plywood, paper, cardboard, or laminated paper, is made by including in the aqueous bonding coating or sizing composition at least two substances being inorganic bromides or oxybromides, at least one being a bromide.

Inventor: KETT BRIAN LAURENCE ARTHUR
IPC: G06F17/10
Filed: 1968-05-10
Abstract: 1,237,451. Digital electric integrator. PLESSEY CO. Ltd. 8 Aug., 1969 [10 May, 1968], No. 22370/68. Heading G4A. Circuit for iteratively integrating a first function with respect to a second function has a multiplier multiplying the functions together and an adder receiving the multiplicand and the previous integrated step, the result being the integrated output. The Specification describes circuits carrying out integrations according to one of the approximations where I = #Y.#X A circuit carrying out the integration according to equation (c) is described with respect to Fig. 5. Binary data #x/2 is fed to a shift register R1 by clock signals # under the control of signal A. Similarly binary data Y is fed to register R2. The least significant bit of #x/2 sets flip-flop B1 to allow Y to be fed through adder A1 to be stored in register R4 if the bit is " 1". Data is recirculated through the registers under control of the clock pulses, the Y data passing stage R3 to be shifted one place to the left so that on multiplication by the next most significant bit of #x the partial product is correctly added to the previous partial product. The result is fed to a further multiplier 10 and a register 9 to an adder 11 and to register 12. If the output of register R4 is #x/2.Yn 1 then multiplier 10 which contains a 1 bit shift register R4 effectively multiplying by 2 will supply #x/2(3Yn-1) when register 9 which delays by one word and inverts will supply Yn- 2 therefore adder A4 will supply register 12 with In - 1 + #x/2(3Yn -1 - Yn - 2) which is the required value. The integrator may be constructed in integrated circuitry with an output from the multiplier being provided so that the circuit can multiply and integrate.

A solution of two liquids is separated into its components by applying the solution through inlet D onto an endless belt B moving through a endless conduit R comprising two successive heating regions H 1 , H 2 , and introducing a carrier gas into the circuit through a pipe Z 1  between the two heating regions so that the gas divides into two streams one of which flows into the first heating region H, while the other gas-stream flows into the second heating region H 2 , the respective temperatures in the two heating regions and the speed of the belt being such that one of the liquids is vaporized from the solution on the belt as it passes through region H 1 , and the other liquid vaporizes from the belt in region H 2 . The vapours of the separated liquids (mixed with carrier gas) are withdrawn through outlets A and C, respectively. Carrier gas may also be introduced into the circuit through pipe Z 2 . Suitable carrier gases are hydrogen, helium, nitrogen, carbon dioxide, oxygen, argon, and methane. The apparatus may be used to separate the solvent and solute of a mixture leaving a liquid/liquid chromatography column; the solute vapours (entrained in gas) are passed to the detector.

Filed: 1954-08-05
Abstract: 766,914. Travelling-wave tubes. STANDARD TELEPHONES & CABLES, Ltd. Aug. 7, 1954, No. 22767/54. Drawing to Specification. Class 39(1). A resistive layer surrounding the helix of a travelling-wave tube operated space harmonically damps out the fundamental mode travelling with the velocity close to that of the beam. Specification 660,793 in which the fundamental mode is maintained while a fast mode is attenuated by a resistive layer is distinguished. In the present case a formula is given for calculating the distance of the layer from the helix in the absence of intervening dielectric. The distance is, however, best found empirically. The layer is preferably on the tube envelope. The helix is a flat tape supported inside the envelope in a closely fitting glass tube, and the beam is annular. The tube may be of the forward or backward wave type.
