Abstract: 1,195,562. Detecting electrically conductive magnetizable particles. J. N. SMITH. June 20, 1967 [June 29, 1966], No.28461/67. Heading G1N. In a device for detecting electrically conductive magnetizable particles in a fluid-flow system, e.g. a lubricating system, resulting from wear in the machinery involved, the particles are attracted by a permanent or electromagnet in the fluid where they bridge gaps between a common first contact and a plurality of second contacts to thereby actuate audio or visual alarms. In one embodiment, Fig 2, the gaps to be bridged are provided in a housing 10 screwed to a fluid-flow conduit wall between a magnetic or non-magnetic electrically conductive annular disc 25, and a plurality of L-shaped conductive electrodes 20 surrounding an annular permanent or electromagnet 21. In a second embodiment, Fig. 5, the permanent or electromagnet 121, is bar shaped, and an electrically conductive and magnetizable foil 200 covering two sides and a part of a third side of the magnet 121, Fig. 6, forms the first contact. The second contacts are provided by a plurality of speed rectangular foil pieces 122. Alternatively the magnet may be annular, the gaps being arranged on the inner surface of the annulus. In use the one contact may be grounded and the second contacts connected each in series with a bulb 51, Fig. 4, and a relay 52. Closure of a gap causes the corresponding bulb and relay to be energized. When all the relays are energized, a further alarm bulb 54 is lit and a warning bell operated. Alternatively, to indicate the rate of wear, the times of closures of the individual gaps may be recorded on a tape which may then be processed in a computer. A plurality of these devices using electromagnets may be used in a complex fluid-flow system, e.g. one where a plurality of conduits join up in a main conduit, one device being arranged in each conduit. The devices in the main conduit is energized primarily, the others being energized either simultaneously or successively by the alarm circuit of the conduit device.

IPC: D06M15/61
Filed: 1965-07-06
Abstract: Textile materials containing wool alone or in admixture with other fibrous materials, e.g. cotton regenerated cellulose, linen and polyester fibres, are shrinkproofed by impregnating them with a solution containing a polyfunctional amidoaziridine compound and an acyclic polyamine containing at least five amino groups per molecule drying them and effecting or completing reaction of the applied compounds by a subsequent heating step.  The polyfunctional aziridine compound may have the formula  <FORM:1078747/D1-D2/1> in which R1, R2 and R3 are hydrogen atoms or alkyl groups containing 1-4 carbon atoms, n is 2 or 3 and Q is an organic or inorganic group, and may be a phosphoramide, carboxamide, carbamate, substituted urea or sulphonamide.  The polyamine may be a polyalkylene polyamine containing the repeating unit.  <FORM:1078747/D1-D2/2> in which R4 is a hydrogen atom or alkyl group and m has a value of 2-6, or polyamino polyalkylene oxide containing the repeating unit <FORM:1078747/D1-D2/3> in which R4 and m are as defined above and b is an integer of 1-20.  The weight ratio of polyaziridine compound to acyclic polyamine in the reaction mixture may be within the range 1:9 to 9:1.  The polyaziridine and acyclic polyamine may be applied to the textile materials as a solution containing 1-10% by weight of the mixture based on the weight of the materials being treated in water or an organic solvent and having a pH of 6-7 by spraying, dipping or padding, excess solution removed by squeezing or centrifuging and the treated materials then dried and heated to 250 DEG -350 DEG F for 1-10 mins.  The materials may also be rendered water and oil repellent by incorporating into the treating solution a fluoro organic compound, e.g. a polyfluoroalkylacrylate.  The materials may be dyed with pre-metallized and acid dyes prior to or after the treatment.

Title: Polymerization of formaldehyde
IPC: H04B17/40
Filed: 1958-09-05
Abstract: Polyoxymethylene having a number average molecular weight of at least 15,000 is obtained by forming polyoxymethylene seed particles at a temperature of at least 25 DEG  C. in an aqueous or alcoholic, or mixed aqueous-alcoholic, formaldehyde solution containing dissolved therein a basic or acidic catalyst that generates hydrogen ions or hydroxyl ions, the solution being so supersaturated with formaldehyde that polyoxymethylene seed particles form spontaneously, and then growing the seed particles at a temperature of at least 80 DEG  C. in a solution containing the basic or acidic catalyst and super-saturated with formaldehyde the saturation of which is below the point at which seed particles begin to form spontaneously. Either the solution has such a formaldehyde concentration at the temperature chosen that seed particles appear and as they grow the formaldehyde concentration decreases, the temperature remaining constant, or the temperature of the solution is lowered so that seeds appear, and after seed particles have formed the temperature is raised so that the seeds grow without further seed formation, additional formaldehyde solution being added if desired to adjust the concentration.  In examples formaldehyde is polymerized in solutions containing, acetic acid, N-ethylpiperidine, trimethylamine, phosphoric acid, N-ethyl-morpholine, 2-dimethylaminoethanol, sodium dihydrogen phosphate, oxalic acid, di-n-propylamine and cyclohexylamine, as catalysts, the solvent, being water, methanol sec-butyl alcohol and ethylene glycol, with dioxane and xylene as diluents.  Other catalysts are mentioned.  The seed particles preferably are grown at 60 DEG  to 125 DEG  C. at atmospheric pressure.  Depending on the solution used the polyoxymethylene may have hydroxyl groups at both ends of the molecule, or an alkoxyl group at one end and a hydroxyl group at the other; in the latter case the hydroxyl group may be esterified.  The polymers may be made into films, sheets, fibres, tubes and rods.  Specifications 557,873, 748,836 and 753,299 are referred to.

Echo-sounding apparatus for visually presenting on a screen the solution of a triangle comprises means for projecting a pair of beams of light of circular cross-section, on to the screen, means for positioning the centres of the crosssections of the beams to correspond to two apexes of the triangle, and means for controlling the radii of the cross-sections of the beams according to the range of the third apex from the first two so that the intersection of the beams indicates the position of the third apex. As shown, Fig. 3, two point source lamps 11, 12 are mounted above camera irises 33, 34. The irises are driven by electric motors 47, 50 and drive potentiometers 45, 52, feed-back from the potentiometers controls the motors to set the iris opening to correspond to the surges. The lamps are movable, being locked by apring- loaded flanges 18, 19, linked by a pin 25 passing through a large hole 20 in the mounting plate. First, a single sounding charge is fired near one of a pair of listening stations, and the iris radii are adjusted, by the received signals from the stations, in accordance with the ranges of the target from the listening stations. The intersecting points of the beam circular images on a screen indicate two possible target positions. Secondly, sounding charges, spaced apart, are fired and a single listening station, near one of the charges, is employed. Two possible target positions are again indicated by the image intersections, one of which is identical with one of the first two indications and which therefore corresponds to the actual target position.
