Patent GB-935013-A (GB)
Title: Process for manufacturing graft copolymers of polyolefines and styrene
Inventor: CALLAGHAN LAWRENCE
IPC: C08J7/16
Filed: 1959-05-27
Abstract: Graft copolymers are made by contacting a film of a polyolefine with styrene in the presence of an aliphatic polyamine at a temperature at which the styrene will swell, but not dissolve, the film. Polyolefines specified are polyethylene and polypropylene. Polyamines specified are tetraethylene pentamine, 1,3-propylene diamine, dipropylene tetramine and aminoethyl ethanolamine. Prior to being contacted with styrene the polyolefine film may be treated to form polymerization-initiating centres thereon, e.g. by exposure to thermal, ultra-violet or high energy ionizing radiation.  When using ultraviolet light the polyolefine film may contain a sensitizer, e.g. benzophenone.  The source of high energy ionizing radiation may be Co-6o or a Van de Graaf generator.  The resulting films may be converted into permselective membranes either by sulphonation or by chloromethylation followed by quaternization.

Title: Electrical Circuit for Measuring A.C. Signal Magnitude
Inventor: BJOR HAKON
IPC: G01R19/00
Filed: 1967-01-20
Abstract: 1,169,689. Voltage measuring. SENTRALINSTITUTT FOR INDUSTRIELL FORSKNING. Jan. 20, 1967, No.18517/69. Divided out of 1,163,193. Heading G1U. The magnitude of an A.C. signal is measured by passing it through a transfer device, varying the transfer factor electrically until the transferred signal, when converted to D.C., balances with a D.C. reference voltage, and determining the transfer factor by passing a D.C. measuring signal through the transfer device. In the Fig. 1 embodiment the signal X to be measured is applied to a transfer device comprising fixed resistor R1 and electronically variable resistor R (e.g. a thermistor with heating element, a light sensitive resistor or a field effect transistor). The R.M.S. value of the transferred signal (from buffer stage A) is derived by R.M.S. detector D and compared with a reference D.C. level a, the difference signal being amplified by B1 and applied to vary R in a direction which reduces this difference to zero. The compression ratio of the transfer device is then a measure of the R.M.S. value of X and is determined by applying the D.C. output voltage X1 of amplifier B2 to the input of the transfer device, comparing the transferred D.C. signal with a second D.C. reference b and applying the difference voltage to the input of B2. X1 will be inversely proportional to the compression ratio and directly proportional to the R.M.S. value of X. High pass filters H1, H2 and low pass filters L1, L2 separate the A.C. and D.C. signals passed through the transfer device. X may be measured in terms of its peak or mean value, or in noise level units (where the X signals represent measured acoustic signals), the R.M.S. detector 3 being replaced by alternative A.C. to D.C. converters as appropriate. In a second embodiment the transfer device is a variable gain amplifier, and buffer stage A and filters H1, L2 are eliminated.

Abstract: 868,437. Forming selvedges. DEWAS, R. June 1, 1959 [June 4, 1958], No. 18522/59. Classes 142(2) and 142(4) Selvedges for fabrics with cut weft picks, or centre selvedges, are formed by inserting short "hairpins" 9 of selvedge thread as shown in Fig. 5; alternatively, there may be a hairpin associated with each pick 21, in which case the limb 9c of one hairpin and the limb 9d of the next hairpin lie in the same shed. Selvedge mechanism. A loop of selvedge thread 5, Fig. 3, is taken into the shed by a needle 4 and retained by a plunger 8 which descends through the warp and through the loop. As the reed commences to beat up the weft, the plunger 8 rises, whereupon a blade 11 on it cuts the loop of selvedge thread, the loop being held down by a presser foot 12 resting on the upper warp sheet; the reed then beats up the two limbs of the loop together with the weft pick. To lay the selvedge thread as shown in Fig. 5, the needle 4 withdraws one limb of the cut loop before beat-up, and inserts it into the next shed where it is held by the shed closing on to it. To ensure that the selvedge threads do not protrude from the surface of the fabrics a ramp 20 crowds the warp threads towards the edge of the fabric as the plunger 8 descends; as the plunger rises, the warp threads spring back into place, straightening the limbs of selvedge thread as they do so.

Title: Improvements in or relating to the production of solid compounds of ammonia, carbon dioxide and water
IPC: C01B21/12
Filed: 1925-07-23
Abstract: 258,048. Synthetic Ammonia &. Nitrates, Ltd., and Coxon, T. July 23, 1925. Ammonium carbonate and bicarbonate.-Solid compounds of ammonia, carbon dioxide and water in a substantially dry condition are produced from ammonium carbamate by treating the latter with carbon dioxide in the presence of water. In an example ammonium carbamate is precipitated by passing carbon dioxide and ammonia into water or other solution, at ordinary or higher pressure, and is removed continuously. The moist crystals are treated with carbon dioxide or gases containing carbon dioxide such as furnace or lime-kiln gases, whereby a dry product practicall identical in composition with commercial ammonium carbonate is obtained. By adding water or steam to the crystals more carbon dioxide is required, and the composition can thus be varied. Part of the water may be combined as solid ammonium bicarbonate by using at first a mixture of ammonia and carbondioxide; the remaining water however is removed by union with the carbamate and the carbon dioxide.
