Abstract: 1,245,968. Differentially reinforced hose. UNIROYAL Ltd. 27 Aug., 1969 [6 June, 1968], No. 26998/68. Heading F2P. A hose for suction and discharge of oil is differentially reinforced from one end to the other by plies, the number of plies being reduced at spaced intervals from the substantially rigid end 1 of the hose towards the relatively flexible end. The core 3 of the embodiment shown is built in the usual way on a mandrel and may incorporate wire cord to give the necessary burst pressure requirements. Four plies 4-7 of bias cut rayon breaker fabric are then applied, each ply being shorter than the underlying ply, and an intermediate body portion 8 is made up of rubber stock and straight cut fabric ply. The hose is then semi-cured off the mandrel in a nylon wrapper and then replaced on the mandrel for completion. After a layer of cement and rubber stock, which completes the body layer 8, a helical wire reinforcement is wound on, the spacing of the turns being increased (e.g. in stages) towards the more flexible end, the gaps between turns being filled by strips 11-13 of increasing width. A further rubber stock layer 14 is applied followed by further reinforcing plies 15-18, the longest being shorter than ply 7. The final body layer 19 is built up of rubber stock and breaker fabric and is formed to give the hose a smooth taper. Finally the hose is vulcanized. Alternative forms of reinforcement may be used, e.g. sheet metal, metal strips, rope or cord.

Title: Method and apparatus for filtering liquids
IPC: A47C29/00
Filed: 1966-06-17
Abstract: 1,075,740. Liquid filter. G. HIRS. June 17, 1966, No. 27206/66. Heading BID. In a liquid filter in which a pump 90 extracts filtered liquid from a chamber 46 separated by filter medium 84 from an inlet chamber 44, a switch 118 responds to decreasing pressure in chamber 46, resulting from clogging of the medium, to stop pump 90, reducing the pressure across the medium before initiating a filter cleaning/renewal mechanism. In Fig. 2 a web of paper filter medium is extended between endless chains 58 and members 42, 52 from supply roll 86 to medium discharge roll 110 and extends across a foraminous part 70..80 of ramp 42 through which filtered liquid passes. Actuation of switch 118 opens contacts 125, supplying pump motor 94, and closes contacts 123 causing motor 98 to drive chains 58. contaminated filter medium being discharged over rubber-coated roll 110 and fresh medium being unrolled from roll 86. Stoppage of pump 90 facilitates withdrawal of medium from foraminous wall 80. In an alternative embodiment, not shown, the filter medium is a fixed wedge-wire screen, and chains 58 carry scrapers which remove solids from the screen, once the pump has been stopped so that the solids are no longer held thereon. In Fig. 1 (not shown) the pump 90 returns filtered liquid by line 24 to a machine tool (22), the liquid being tool coolant. Switch 118 may operate in its two directions at different pressures so that the movement or scraping action proceeds for a short time once started. The pump stoppage permits liquid in line 24 to drain back causing reduction in pressure difference across the filter.

Title: Improvements in and relating to the manufacture of rubber and the like
IPC: C08J3/03
Filed: 1930-09-12
Abstract: A composition for making rubber articles, rubberized fabrics, coating fibres, paper, &c. consists of an emulsion of rubber in an aqueous dispersion of an oxygenated alicyclic compound e.g. cyclohexonal or cyclohexanone or mixtures thereof.  The alicyclic compound may be dispersed in an aqueous solution of a water-miscible colloid such as soap or saponin.  The plastic compound may include natural or synthetic rubber, reclaimed rubber, vulcanized rubber, balata, guttapercha, &c. or mixtures thereof, also rubber substitutes such as an aqueous dispersion of Brown Factice prepared by incorporating, with a dispersing agent in aqueous solution, the product of reaction under heat of elemental sulphur with an unsaturated fatty oil while the reaction mixture is still fluid and hot e.g. at 100-90 DEG  C. Naturally aqueous dispersed rubber, such as natural or vulcanized rubber latex may also be added.  The composition may be employed for the manufacture of rubber articles according to Specifications 233,458, 284,608, 292,964, 301,476, and 330,520, [all in Class 70, Indiarubber &c.].  The rubber may first be subdivided and worked up with a proportion of the alicyclic compound e.g. 10 per cent, to a plastic homogeneous mass, and then dispersed by the addition of the dispersing agent for the alicyclic compound e.g. a soap solution of 5 to 10 per cent strength.  Alternatively the dispersion of the alicyclic compound may be prepared first and the rubber then added, with or without further additions of the said dispersion or one or the other component thereof; or the dispersion may be formed in situ during the manufacture of the rubber emulsion by alternate additions of the alicyclic compound p  and the dispersing agent therefor. Before use, the alicyclic compound and its dispersing agent may be partially recovered, e.g. by filtration, centrifugation, or deposition, and also rubber compounding ingredients such as vulcanizing agents, accelerators, fillers, dyes, softeners, antioxidants, &c. may be added. Detailed examples are given.

Convention date, Oct. 3, 1930. [Classes 39 (i) and 40 (v).] In receiving or amplifying sets with one or two thermionic valves having cathodes directly heated by alternating current, the cathodes are bridged by a potentiometer with a resistance of 10 ohms or less, a tapping on the potentiometer constituting the connecting point for the grid and anode circuits. In the two-stage resistance-coupled amplifier shown in Fig. 1, 'the cathodes 9, 10 of the valves 7, 8 are heated by alternating current from the lighting main through a transformer 11, and are bridged by the potentiometer 23, the tapping 24 of which constitutes the connection for the grid and anode circuits. The use of a potentiometer of 10 ohms or less resistance reduces humming, which may be further reduced by using valves in which only part of the heated filament is effective. A suitable arrangement of this kind is shown in Fig. 2, in which the -anode 15 is so short in relation to the filament 2 and grid 14 that only the central part of the filament is effective. In a modified arrangement the same result is secured by coating the middle portion of the filament with highly emissive material.
