Title: Method of producing non-linear, hardenable and neutral synthetic resins
IPC: C08G18/68
Filed: 1962-10-29
Abstract: Non-linear, hardenable and neutral synthetic resins are produced by a process which comprises reacting in the presence of a polymerization catalyst a component containing hydroxyl groups with a complex isocyanate dissolved in an unsaturated copolymerizable monomer containing no hydroxyl groups, the complex isocyanate being prepared by reacting a polyfunctional organic isocyanate with at least one compound containing hydroxyl groups, and at least a major part of the component containing hydroxyl groups being one or more esters or esteramides of (A) castor oil and/or shellac and/or one or more natural or synthetic materials having a chemical constitution similar to that of castor oil or shellac with (B) one or more polycarboxylic acids, anhydrides or esters, at least one of the polycarboxylic acids, anhydrides or esters being unsaturated.  The hydroxyl containing component may be modified by the addition of an hydroxy polyether, e.g. higher polyethers of glycol, glycerine or alkanolamines, or by products obtained by (1) reacting one or more components (A) with one or more unsaturated polycarboxylic acids to form acid esters free from hydroxyl groups which are then esterified with monohydric alcohols, or by (2) reacting one or more components (A) with a saturated polycarboxylic acid or with saturated, acid, branched esters, and esterifying the product with 1 mol. of alcohol for each mol. of free acid group.  Components (A) specified are castor oil, holebo oil, shellac, oxidized unsaturated fatty oils, hydroxyl-containing esters of polymeric fatty acids, natural or synthetic glycerides of hydroxy fatty acids, blown fatty oils, fatty acid esters of carbohydrates, reesterification products of castor oil or unsaturated fatty oils with, e.g. aminoalcohols, and hydroxyethylated fatty acid amides.  Unsaturated copolymerizable monomers specified are styrene, vinyltoluene and allyl, vinyl or acrylic esters.  The complex isocyanates are prepared by reacting the organic isocyanate, dissolved in the monomer, with a glycol, polyhydric alcohol, hydroxyl containing ether or ester or a component (A). The catalysts may be peroxidic hardeners and accelerators of amine or metal soap character.

Abstract: 1,192,007. Automatic moisture content control. MICROWAVE INSTRUMENTS Ltd. and J. BILBROUGH. Sept. 8, 1967 [Sept. 13, 1966], No.40799/66. Heading G3R. A desired moisture content is produced across the width of a travelling web by passing the web through a wave-guide which detects moisture content at a number of positions across the width and automatically controls the heating at corresponding positions across the width. In Fig. 4, a wet paper web W, moving to the right, passes a slot in a wave-guide 44 which is reciprocated continuously or step-by-step across the width of the web. A switch 36, operated by movement of the waveguide, connects the output of a microwave detector, associated with the waveguide and responsive to the moisture content of the web, in succession to a number of controllers C 1 -C 5  associated with heaters H 1  -H 5  across the width of the web so that each heater is controlled in turn to maintain a desired moisture content at its position. The heaters may be energized by gas, steam, or highfrequency alternating current. Control of the heaters is assisted by a further reciprocated wave-guide 42 detecting the moisture content of the incoming web. Further controlled heating may be provided downstream of wave-guide 44 by heaters HB which may utilize the microwave power of the wave-guide. Reciprocation of the wave-guide is by an electric or fluid-pressure motor. In a modification, the wave-guide is stationary and a number of slots, provided at different positions across the wave-guide, are associated with detectors separately connected to the controllers for simulataneous operation.

Abstract: 1,204,708. Automatic alarm systems. GENERAL ELECTRIC CO. 12 Sept., 1967 [25 Nov., 1966], No. 41676/67. Heading G4N. [Also in Division G1]  The presence of hydrogen or other reducing gas in air arising for example from incomplete combustion is detected by a detector comprising a substrate (1, Figs. 1, 2, not shown) one face of which is coated with a thin film metal oxide resistance element (5) on which is deposited an activating catalyst (6) in the form of small islands of thin film. On the other face is a thin film conductor element (4) for heating the substrate to within the range 200-380‹ C. Alternatively (Fig. 7, not shown) the substrate may be tubular. The resistance element (5) may be an oxide of tungsten, molybdenum, chromium, niobium, nickel, iron or titanium. The catalyst may be of platinum, iridium, rhodium, gold or palladium deposited by vacuum evaporation. The substrate may be quartz, alumina, beryllia, calcia silica glass or yttria. Indicator and alarm circuit.-The metal oxide reistance element 23, Fig. 5, forms with a selected one of capacitors C24, C25, C26, C27, and a neon lamp 28, a relaxation oscillator. In the presence of the catalyst hydrogen in the gas directed over the element 23 (e.g. by a pump) reacts with the metallic oxide of the element to change its resistance, and thus the time constant of the circuit changes. As ambient hydrogen concentration increases R23 decreases and 1/RC, which is proportional to the frequency of flashing of the tube, increases. At 10 c.p.s. to 20 c.p.s. the bulb appears to be lighted continuously. The instant this condition is reached corresponds to a definite value of R x C and since C and R are known an indication of the hydrogen concentration is obtained. An audio tone the frequency of which varies with hydrogen concentration may be used as an output indicator. In an alternative circuit, Fig. 4, the change in resistance of the metal oxide 16 controls an S.C.R. 15 to operate an alarm 14.

Abstract: 1384135 Preserving food INOUE-JAPAX RESEARCH INC 8 Sept 1972 [10 Sept 1971] 41692/72 Heading A2D A method of preserving food comprises the steps of (a) applying a superatmospheric pressure of 2 to 8 atmospheres through a fluid medium to said food and cooling the food sufficiently to freeze it, (b) maintaining the food in a frozen state under a superatmospheric pressure of 2 to 8 atmospheres, and (c) defrosting said food by heating while maintaining the food under a superatmospheric pressure of 2 to 8 atmospheres until the food is defrosted. The fluidmedium may be a non- oxidising gas such as nitrogen, carbon-dioxide, helium and argon or a liquid such as water. Step (a) of the above method may be carried out in the pressure box 21 (Fig. 4, not shown), wherein the food to be treated is placed in this box and a superatmospheric pressure applied through a suitable fluid medium via duct 23. Step (b) may then be carried out in the freezing apparatus illustrated in Fig. 3 (not shown), wherein a freezing current is fed from duct 25 and circulates through the freezing space to bring the food within box 21 to a preselected freezing temperature and, if desired, maintain it at that temperature. Step (c) of the method may be carried out by raising the temperature of the freezing space to permit defrosting or by using the apparatus shown in Fig. 2, wherein a frozen food 2 maintained under a superatmospheric pressure by the compressor 4 is heated by electrodes 13 and 14. The step (c) may also be carried out by subjecting the frozen food to high-frequency dielectric heating, ultra-violet radiation or submersion in water to a depth of at least 10 metres. Examples describe the treatment of pork, lettuce, tomatoes, and peaches.
