Title: Improvements in poly aromatic oxides
IPC: C08G65/44
Filed: 1960-06-10
Abstract: The invention comprises polymers having an average molecular weight of at least 500, consisting of aromatic units linked by oxygen atoms, in which the aromatic units (a) are substituted by at least one alkyl, aryl, alkenyl, alkoxy, aryloxy or alkenyloxy radical or a combination of these radicals (such substituted radical when it contains an aliphatic carbon atom joining it to the aromatic nucleus, having at least one hydrogen atom alpha to the aromatic nucleus) and (b) at least one hydrogen atom meta to one of the oxygen atoms joining individual aromatic units, the polymer having terminal atoms or radicals at least one of which, if they existed in ionic form, would be an anion, and at least one of which would be a cation.  The polymers are obtained from monomers of formula: <FORM:0959283/C3/1> where Ar is an aromatic nucleus, e.g. a benzene, naphthalene, anthracene, diphenyl, diphenyl alkane, diphenyl ether or diphenyl sulphide nucleus, R is the substituent mentioned above, X is an atom or radical which would be an anion in ionic form, chlorine, bromine, iodine, nitrate or sulphate, Y is an atom or radical which would be a cation if in ionic form, e.g. hydrogen, sodium, potassium, silver or lithium, a is at least 1, b is 1 or 2, c is 1 or 2, and d is 1, 2 or 3; polymerization occurs in the presence of a catalyst by linking Ar units through the oxygen atoms with removal of a compound XY.  In examples polymers are obtained from 2,6-dimethyl-4-bromophenol, 2,6-diisopropyl -4- bromophenol, 2,6-diallyl -4- bromophenol and 2-phenyl -4- bromo -6- methyl phenol, the catalysts being iodine, ultraviolet light, silver oxide, lead tetra-acetate, potassium ferricyanide, benzoyl peroxide and lead dioxide.  Other starting materials are mentioned.

Title: Improvements in or relating to direct-acting pumps
IPC: F04B9/12
Filed: 1931-07-18
Abstract: 379,814. Pumping-engine valve gear. WEIR, Ltd., G. and J. and LANG, C. R., Holm Foundry, Cathcart, Glasgow. July 18, 1931, No. 20585. [Class 122 (ii).] To prevent injury due to pressure variations in pipe lines fed by two or more pumps, the operation of the pumps in out-of-phase relation is ensured by providing each pump with a valvegoar including, in addition to valve-actuating means operated by the pump piston, a valveactuating device independent of the pump. In the construction shown, the valves 1 are actuated by rods 12 pivoted at 13 to levers 14 which have ends engaging rotatable fulcrum pins 15 carried by the pump rods 10, 11. An electric motor 17 through gearing 18, 19 drives shafts 16 with discs 20 and pins 21 coupled by connecting-rods 22 to pins 23 on the levers 14. The supports of the pins 13 slide on guides 24. The rotary shaft driving the worms 18 is common to all the pumps, and it may be driven by one or more electric motors or turbines. Each pump may have its own rotating shaft and motor, and the motors may be run synchronously. One or more pumps may be put out of action. The mechanism shows the pumps at each end of their strokes to allow the pump valves to seat quietly. The shafts 16 and piston-rods 10 move the valves in opposite directions. The valves are in their mid-position when the connecting-rods 22 are at the end of their strokes. With the piston on the right at the end of its stroke, the shaft 16 moves the valve 1 down and supplies steam to the top of the cylinders and permits exhaust from the bottom. The piston 9 moves down at a speed dependent on the speed of the shafts 16. If the piston speed overruns or lags behind the speed of the shaft, the piston-rod rocks the lever 14 about the connecting-rod pin 23 and modifies the admission. The rod 22 may reach the dead centre slightly before the piston 9 is at the bottom of its stroke ; further piston movements then cuts off the steam supply. In a modification the valve spindle carries adjustable tappets which engage a crosshead connected to the rod 14. The tappets comprise pinions which are screwed to engage right- and lefthanded threads on the spindles. The pinions slide relative to pinions on the guides which may be rotated by hand to modify the relative action of the pumps.

Title: Production of non-woven bonded materials
IPC: D04H1/4282
Filed: 1964-05-20
Abstract: In a process for the production of a non-woven bonded fibrous material a web containing a major proportion of non-plasticisable fibres, a minor proportion of plasticisable fibres and a plasticiser for these fibres is heated, without pressure, to a temperature at which the fibrous structure of the plasticisable fibres is destroyed so that the material thereof coalesces into beads and acts as a bonding agent for the non-plasticisable fibres which remain undamaged at the temperature to which heating takes place.  The amount of plasticiser added is controlled to ensure that the melting temperature of the binder fibres is sufficiently lowered to prevent damage occurring to the non-plasticisable fibres.  Suitable plasticisable fibres referred to include polyvinyl chloride or a copolymer of vinyl chloride with another monomer, such as vinyl acetate, and such fibres may advantageously be present in a proportion of 10% to 35% by weight.  Non-plasticisable fibres referred to include regenerated-cellulose rayon, cotton and wool. Plasticisers referred to include N-butyl-benzenesulphonamide and trichloroethyl phosphate and these are preferably added to the fibres after formation of the mixed fibre fleece.  The bonded webs produced may be further treated e.g. to render them less inflammable, hydrophobic, crease-resistant, stiffer or more resilient.  In Example 4 an impregnant comprising 50 parts polyvinyl chloride, 20 parts antimony trioxide, 200 parts methylene chloride and 700 parts trichlorethylene is used to render a bonded web less inflammable.ALSO:In a process for the production of a coated non-woven bonded fibrous material a web containing a major proportion of non-plasticisable fibres, a minor proportion of plasticisable fibres and a plasticiser for these fibres is heated, without pressure, to a temperature at which the fibrous structure of the plasticisable fibre is destroyed so that the material thereof coalesces into beads and acts as a bonding agent for the non-plasticisable fibres which remain undamaged at the temperature to which heating takes place and coating the bonded material with a foam of a polyvinyl chloride dispersion.

Title: Improvements in and relating to the covering of wood with resistant coatings
IPC: B27K3/15
Filed: 1935-07-23
Abstract: Resistant coatings on wood are produced by treating wood with a solution of a phenolformaldehyde condensation product capable of hardening at low temperatures and then hardening at temperatures below 80 DEG  C. and, if desired, at atmospheric temperature. Further coatings of solution of similar resins may be applied afterwards or the wood may be pretreated with pore fillers having as a basis a similar resin and containing, if desired, fillers such as kaolin, bole, asbestos meal, magnesium aluminium silicate, glass dust, slate meal, potato flour, heavy spar, zinc white, white lead, iron oxide red, or ochre (or other resins such as colophony, shellac and vinyl resins).  The phenol-formaldehyde condensation product is employed as an aqueous or alcoholic solution, such alcohols as butyl and propyl alcohol being preferred.  Dyestuffs may be added if desired.  Other resins such as colophony, shellac and vinyl resins and other solvents such as ethylene glycol, ethylene glycol acetate, ethyl alcohol or acetone may be added to the phenol-formaldehyde solution or the hardened product may be varnished with other varnishes such as oil or cellulose - derivative products.  The coated products are of use in the manufacture of furniture, radio apparatus, perambulators, benches, chair seats, table tops and wainscotting.  In examples, resins prepared by condensing phenol or cresol with formaldehyde in the presence of caustic potash, caustic soda, sodium bicarbonate, dimethylamine or acids such as lactic, phthalic or phosphoric and, if desired, neutralized with acids such as hydrochloric, sulphuric, nitric, benzoic, salicylic or phthalic acids, are used in aqueous or alcoholic solution to coat wood and the coating afterwards hardened.  A pore filler comprising a similar resin and a filler such as bole may be used to pretreat the wood. Specification 377,587 is referred to.
Patent GB-694734-A (GB)
Title: Improvements in or relating to the preservative impregnation of wood
IPC: B27K3/00
Filed: 1950-08-23
Abstract: Wood impregnated with oil-borne preservative compounds such as toxic salts is subjected in a closed space to solvent vapours whereby the wood is heated and excess toxic salts extracted from the wood by solvent condensing on the wood.  The wood is then subjected to a vacuum to remove condensate and excess impregnant oil.  The vapours may be those of the oil used in the impregnant or a different solvent of the same or lower or higher boiling point.  In the last instance the vacuum treatment may be omitted. Preferably the treatment with vapour and vacuum is repeated until there is a uniform concentration of preservative throughout the wood and the wood is substantially free from impregnant oil.  The heating temperature is kept below 400 DEG F to avoid damage to the wood, solvents with boiling points not higher than 320 DEG F and not lower than 240 DEG F, unless non-inflammable, being preferred. Examples of solvents are V M and P naphtha, Stoddard solvent, toluene, xylene, trichlorethylene and perchlorethylene.  Examples of preservative compounds are copper zinc and mercury organic compounds, chlorinated and nitrated organic aromatic compounds and miscellaneous compounds such as beta-naphthol, orthophenylphenol, rosin amine and rosin amine acetate.  Examples of the treatment of pine impregnated with copper naphthenate and using a variety of vapours are given, together with figures for copper, oil and moisture concentrations in various parts of the wood after treatment.  The treatment is stated to prevent bleeding and surface accumulation of preservative and to remove natural wood resins and gums, making the surface receptive to paint.  It is stated that the process is applicable to wood fibre compositions such as wallboard as well as wood in the natural state.  Specifications 655,064, 687,113, [both in Group VIII], 6844/02, 19737/04 and 24451/04, [all in Class 140], are referred to.

Title: Electrical apparatus and gauging device
IPC: G01B7/28
Filed: 1971-04-19
Abstract: 1317495 Peak detector; measuring roundness electrically BENDIX CORP 19 April 1971 [ 4 Feb 1970] 21107/71 Heading G1N and G1U A peak detector comprising an operational amplifier 80, Fig.3, and a capacitor 75, is characterized in that the output of the amplifier 80 is coupled to the capacitor 75 by two oppositely poled uni-directional conducting paths including FET 71 and diode 83, and FET 74 and diode 82. In use, a switch 66 is moved to the positon shown thereby opening both FETs. As a result, whatever the previous potential on capacitor 75 it now follows the potential of the input 91 to the amplifier 80 from a signal source 27. After a short time, the upper FET 74 is closed, since its driver 73 is energized via a monostable circuit 72, so that the potential on capacitor 75 then follows the positive peaks of the input signal. The potential on capacitor 75 is amplified by a further operational amplifier 93, and the connections to the upper plate of the capacitor 75 are surrounded by a screen 95, at the same potential as the upper plate, in order to reduce leakage therefrom. Negative peaks of the input signal 27 may be detected by a similar circuit 80A, etc., and the negative and positive peak outputs may be utilized separately or their difference, derived by a further amplifier 63, may be used. The circuit described forms part of a system for gauging a brake drum. A differentialtransformer transducer 25, Fig. 2, is swept over the inner surface of a brake drum 22, firstly at a high level 35 for half a revolution, and then at a low level 37 for half a revolution. The resulting signal is detected, 27, and applied to a voltagevariation circuit 30, constructed as shown in Fig. 3. The resulting voltage, which represents the difference in amplitude between the most positive peak and the most negative peak, is compared with pre-set maximum tolerance voltages 40, 41, 42, 43, and lamps 54, 55, 56, 57, respectively, are energized if a tolerance is exceeded. A further signal 64 from the variation circuit may be used to classify and count the drums into size ranges. A record 78 could be made of the result, or the drums could be marked with their sizes.
