Title: Improvements in or relating to adhesive compositions for splicing flexible sheet material
Inventor: GROVE JEROME D
IPC: C09J7/10
Filed: 1955-11-25
Abstract: Heat-curing adhesive compositions comprise (1) a rubbery butadiene-acrylonitrile copolymer; (2) an oil-soluble heat-advancing phenolaldehyde resin; and (3) a monomeric methylenequinone-liberating dihalomethyl alkyl phenol having the halomethyl groups ortho to the phenolic hydroxyl.  (1) may be prepared from mixtures containing additional monomers, e.g. isoprene; (2) may be prepared by alkalicatalysed condensation of 1.2 to 1.6 mols. of an aldehyde, e.g. formaldehyde, with 1 mol. of a substituted phenol, e.g. para - tertiary - amyl phenol; (3) may be 2,6-dibromomethyl-4-methyl phenol or 2,6-dichloromethyl-4-methyl phenol.  Thermoplastic resins, e.g. the glycerol ester of a resinous extract of pine wood and acetone-soluble phenolic resins, zinc oxide, plasticisers, e.g. dibutyl phthalate, and retarders, e.g. salicylic acid, may be added. Films obtained by solvent casting the compositions from acetone on polyethylene coated paper and stripping or coating on a reinforcing sheet, e.g. cloth, paper, regenerated cellulose sheet or metal foil, may be used to form butt and lapped splices in flexible sheet material, e.g. paper, cloth, cellulosic and resinous films.

Title: Improvements in or relating to the polymerisation of olefins
Inventor: REAY WALTER HARKNESS
IPC: C08F10/00
Filed: 1957-11-07
Abstract: A low-pressure process for polymerising an olefinic hydrocarbon is carried out in a liquid medium and reaction mixture is withdrawn from the polymerisation reactor during polymerisation, a minor portion of the withdrawn mixture is removed for working-up the polymer product and a major proportion of the withdrawn mixture returned to the reactor the major portion being separated into a concentrated slurry fraction which is returned to the reactor and a solvent fraction which is cooled before being returned to the reactor.  In a modification the reaction mixture is separated into a solvent fraction and a concentrated slurry fraction, the solvent fraction being returned to the polymerisation zone after cooling and the concentrated slurry being divided into a minor portion which is removed for working-up and a major proportion which is returned to the reactor.  The concentrated slurry may be returned to the reactor as a separate stream, the reaction mixture may be continuously withdrawn from the reactor during polymerisation, the solvent fraction may be mixed with fresh solvent either before or after cooling which may take place in a heat exchanger, the withdrawn mixture may pass through a time tank before separation the tank preferably having an agitator and vent for removing gaseous material. The withdrawn reaction mixture may be separated in a continuous centrifuge or a hydro-cyclone and the concentrated slurry returned to the reactor by means of a screwconveyer.  The usual Ziegler catalysts may be used in the polymerisation while ethylene is the specified olefin. Apparatus for carrying out the process is described.

Title: Improvements in or relating to the roasting of sulphide ores
IPC: C22B1/02
Filed: 1931-12-15
Abstract: <PICT:0394650/III/1> Sulphide ores such as zinc blende, or pyrites, or partly burnt pyrites, particularly cuprous pyrites, or other sulphur - containing materials are roasted in the presence of a gas containing free oxygen and at least 20 per cent, and preferably 25 per cent, sulphur dioxide at 600-800 DEG  C., preferably 700 DEG  C., whereby non-ferrous metals are converted to sulphates.  The roasting may be effected in say a rotary kiln or shaft furnace which may be the same as or separate from that in which initial partial oxidation is effected.  The sulphur dioxide concentration is preferably obtained by circulating a quantity of the gases issuing from the burner after enrichment in sulphur dioxide, preferably by concentration, e.g. by liquefaction or by washing with a solvent and subsequently recovering the dissolved gas by heating or reduced pressure or both.  The combustion air and sulphur dioxide may be preheated, the specified temperatures of from 35-310 DEG  C. being dependent on the sulphur content of the raw material.  In particular embodiments of the process, pyrites is fed to the upper end of a shaft furnace 1.  Herein oxidation of the pyrites commences with the production of iron oxide, sulphur dioxide and possibly free sulphur, a temperature of 800-1000 DEG  C. being obtained.  Effluent gases pass through a dust collector 5 and cooler 6 to a concentration plant 7, from which part of the sulphur dioxide is withdrawn from the cycle.  The remainder, together with a variable quantity of gases which is byepassed, is divided into two portions, one of which is introduced at an intermediate part of the furnace 8 in which sulphatization is effected and serves to control the temperature of the upper end of the furnace.  The other portion may be introduced at the bottom of the furnace with the entire combustion air, or alternatively, at a depth 10 below the point 8.  In this latter modification, some air 11 is added either at this depth 10, or between this point and the point 8.  The remainder of the combustion air is admitted at the bottom of the furnace 3, producing a strongly oxidizing zone at 400-700 DEG  C. below the sulphatizing zone. According to the Provisional Specification, lead sulphate present in the roasted ore may be recovered by leaching with brine, or, after dissolution of the soluble sulphates in water, by volatilization. Specifications 317,665, [Class 82 (i), Metals, Extracting &c.], and 359,478 are referred to.

Title: Improvements in or relating to Resistor Comparison Circuits
IPC: G01R17/10
Filed: 1967-07-28
Abstract: 1,181,298. Measuring bridge circuits. ROSE MOUNT ENG. CO. July 28, 1967 [Aug. 25, 1966], No. 34899/67. Heading G1U. A bridge circuit is of the type where the unknown resistor R is interchanged between adjacent arms so as to eliminate the effects of lead impedances L1-L4. The system is arranged so that while the resistor R is connected as an arm in a first parallel bridge branch containing a further arm 20 Fig. 2 a resistor 25 is connected in an arm of a second parallel branch, while when the resistor R is connected into the second branch, the resistor 25 is switched out and a resistor 22 switched into the first branch. The resistors 22, 25 are ganged together and keep the same value. They are adjusted either manually or automatically until the detector 80 shows a continuous null throughout repeated switching operations. The bridge excitation may be either D.C., A.C. or d.c. switched in synchronizm with the operation of the switches 21, 24, 26. If a reversible excitation is used, the switches may be replaced by appropriately poled diode arrangements Fig. 8, (not shown). In an alternative embodiment Fig. 3 designed to avoid the need to adjust the known resistors to the same value as the unknown, and facilitate range changing, current dividing networks 30, 35 are included in the two bridge branches, and these may be connected either way round across fixed resistors 33, 38 by the ganged switches 31, 32, 36, 37. It is shown in the Specification, by using an analytical delta to Y transformation, that the impedance in series with R in the bridge arm containing R will be Y (K-X)/(2K+Y), where Y is the fixed resistance 33 or 38, 2K is the full resistance of each current divider and X is the amount from the centre by which each divider is adjusted, while that in the adjacent arm is Y (K+X)/(2K+Y). When X is adjusted so that a null is obtained for repeated switchings, then R (2KY)/(2K+Y) (X)/(K) i.e. R = the resistance of each divider network, times the fractional setting of each divider. Range changing is achieved by adjusting Y in appropriate steps, the maximum range being 2K when Y is open circuited. The bridge makes use of a switched D.C. supply 40, which is applied via a switch 42 and capacitor 43, both arranged to operate to reduce transients. A simple logic circuit is described for operating the switches in the system at the correct times Fig. 7, (not shown) and a suitable arrangement of resistor strings for use in the variable current potentiometers is discussed Fig. 6, (not shown).
