Title: Improvements in or relating to insecticidal compositions
IPC: A01N25/00
Filed: 1945-04-11
Abstract: An insecticidal composition comprises dichloro-diphenyl-trichlorethane (D.D.T.) and a substance which has the property of attracting pests thereto.  The attractant may be a substance or a mixture having either a strong attraction for a particular pest, e.g. (a) geraniol or geraniol and eugenol for attracting Japanese beetles; (b) methyl esters of benzoic, acetic, malonic, propionic and oxalic acids and ethyl esters of malonic, propionic and oxalic acids for attracting codling moths; (c) fish meal for attracting clothes moths and carpet beetles and (d) formaldehyde for attracting house flies, or a general attraction for a number of different pests, e.g. sugars, molasses, syrup, honey and beer.  The attractant may itself be hygroscopic or a hygroscopic agent, e.g. glycerin, glycols and gums, such as Acacia, Bassora, Ghatti, Senegal and Tragacanth, may be incorporated in the composition.  The D.D.T. and attractant mixture may be diluted with an inert carrier or vehicle, e.g. an oil-bound water paint, paperhanger's paste or finely-divided clay with or without suspending agents, and preferably also with a wetting agent such as a soap, a sulphated alcohol or an alkali salt of an alkyl naphthalene sulphonate.

Patent GB-493066-A (GB)
Title: Improvements in or relating to the production of stiffened fabrics and articles madethereof
IPC: D06M17/02
Filed: 1937-03-31
Abstract: A fabric containing a thermoplastic derivative of cellulose is stiffened by subjection to heat and pressure in the presence of water and both a water-soluble and a water-insoluble plasticizing agent for the cellulose derivative.  The fabric may be woven, knitted or netted from cellulose derivative yarns, together, if desired, with non-thermoplastic yarns.  The thermoplastic cellulose derivative may be present as yarns in the fabric as a coating thereon, or as a film or powder applied thereto; if powder is employed it may be mixed with a plasticizing agent and gum or other binder.  The plasticizers may be present in the spinning solution or applied to the fabric, by dipping, spraying or padding, preferably as a solution in a volatile solvent which is a swelling or penetrating agent for the cellulose derivative, e.g. benzene methyl or ethyl alcohol.  Preferred plasticizers are dimethoxyethyl phthalate and triacetin.  Finely divided pigment may be incorporated.  Compound fabrics may be formed by uniting alternate layers of the fabric containing a thermoplastic cellulose derivative with other fabrics by treatment as above, or by uniting two or more such fabrics; the plasticizing agents may be present on the non-thermoplastic material, e.g. two layers of cellulose acetate fabric may be united with an intermediate fabric consisting wholly or partly of non-thermoplastic material and containing the plasticizing agents.  The fabrics are suitable for collars, cuffs, shirt fronts, parts of hats and stiffening linings. The heat and pressure may be applied locally to produce designs, and the plasticizing agents may also be applied locally. In examples: (1) a fabric consisting of acetone-soluble cellulose acetate is dipped in a solution of dimethoxyethyl phthalate and triacetin in ethyl alcohol, and the solvent evaporated.  A layer of cotton or linen fabric is placed on each side of the treated fabric, the whole wetted and pressed with a hot iron or calender; (2) a compound fabric made according to example 1 is interposed between two layers of fabric consisting wholly or partly of cellulose acetate.  The assembly is wetted and pressed on both sides with padded hot irons or calenders. A stiffened fabric results in which the outer layers of cellulose acetate are unaltered in appearance.

Title: Improvements in or relating to supersonic wave apparatus, particularly for use in light modulating
IPC: B06B1/06
Filed: 1940-05-27
Abstract: 539,627. Supersonic light modulators. SCOPHONY, Ltd., and DODINGTON, S. H. M. May 27, 1940, No. 9280. [Class 40 (iii)] The piezo-electric crystal of a supersonic light modulator is mounted substantially parallel to a reflecting end plate of the liquid container opposite to the operative side of the crystal, and means are provided to adjust the position of said crystal to said back plate to broaden the resonance curve. The adjustment is such that the waves reflected from the back wall at the natural frequency of the crystal reach the crystal in reversed phase and therefore reduce the peak output, while for certain side frequencies the reflected waves reach the crystal in phase and aid the crystal vibration. A flat-topped resonance curve 4 megacycle wide with a crystal frequency of 18 megacycle can thus be obtained.

Abstract: 1469281 Float glass process PPG INDUSTRIES Inc 5 March 1974 [6 March 1973] 9746/74 Heading C1M In the float glass process the stream of molten glass being flowed on to the molten metal bath is confined between a spaced pair of parallel restraining members 31, the glass being caused to decreasingly wet each restraining member as the glass passes along the member. In one embodiment (Figs. 2 and 3) the member is formed of a refractory material such as graphite or "monofrax-m" (96% Al 2 O 3 , 4% Na 2 O) in which the degree to which it is wetted by glass depends on temperature. The member is accordingly provided with graphite resistance heaters 52 located in wells 34 which are filled with molten tin 53. Thermocouples are provided embedded in the member 31 and are connected to a temperature control device. Optical pyrometers are used to detect the glass temperature. In a second embodiment differential wetting is achieved using a lubricating agent such as molten tin or other metal or metal salt. As shown (Fig. 4) the restraining member is provided with a trough 61 along its top. The trough has a sloping weir 62 along the side of the member facing the glass. The molten tin is continuously supplied to the trough so that it overflows the weir. Since the weir slopes downwardly in the downstream direction more lubricant overflows the weir at the downstream end of the member causing the required decrease in wetting.
