Title: Laminated articles for electrical purposes
IPC: B29C70/00
Filed: 1956-05-02
Abstract: A resin emulsion is prepared by heating a phenol (e.g. phenol, m-cresol, 3-5-xylenol, resorcinol a -phenethyl-phenol, or a mixture of phenols) and an aldehyde (e.g. formaldehyde, acetaldehyde furfural, or a mixture of aldehydes) or a mixture of phenol, formaldehyde and acetone in the presence of an alkaline catalyst such as barium hydroxide, with or without methanol under reflux at the boiling point of the mass.  The mass is then treated to make it non-alkaline, preferably after cooling, by adding an acid or acid-forming substance, e.g. formic acid, acetic acid, oxalic acid, carbon dioxide, hydrochloric acid, sulphuric acid or phosphoric acid (solid carbon dioxide is used in Example 1).  If the resulting salt of the alkaline catalyst is insoluble it may be filtered off.  The mass is then partially dehydrated under reduced pressure.  An emulsifying agent (gum acacia in Example 1) is dissolved in water and the resulting solution added to the resin with fast stirring.  Other emulsifying agents mentioned are gum arabic, gum ghatti, gum tragacanth, alkyl sulphates, alkyl aryl sodium sulphonates, sulphonated ethers, and the polyethylene ethers of sorbitan mono-ester of a fatty acid containing 12-18 C. The mixture forms an emulsion with water as the continuous phase, which may be further diluted with water.  An aniline modified resin is prepared by reacting 23 parts synthetic phenol, 39 parts formaldehyde, 11 parts aniline and 2 parts of ammonia solution (29.4%).  The product is dissolved in 12 parts of isopropanol and 12 parts of toluol. Uses.-Both resins are used in the manufacture of glass fibre mat laminates (see Group VIII).

Abstract: 996,494. Cathode - ray tube mounting. KOLSTER-BRANDES Ltd. April 5, 1963 [April 9, 1962], No. 13571/62. Heading H4T. [Also in Division H1] To reduce the likelihood of a cathode-ray tube implosion, the glass envelope is stressed by applying forces by means of pressure pads at the corners of the rectangular faceplate in directions towards the tube axis. As shown, the tube is surrounded by a steel stress band 2, Fig. 1, formed in two parts drawn tightly together by adjusters A. The stress band is seated on a plastics or rubber band 6 formed with a mounting flange 6a. Alternatively, steel band 2 may be coated with plastics to prevent damage to the glass envelope. At the corners of the tube, pressure pads are provided between bands 2, 6 and angle brackets B are riveted to stress band 2. Brackets B are bolted to a tube cabinet for mounting purposes, and also by tightening the bolts, each bracket tends to pivot about its bend, and so cause additional pressure on the tube corners. This method of stressing the tube envelope may be used with a band 2 not under tension. In an alternative arrangement, pressure pads 20, Fig. 4, at the corners of tube 25 are urged inwards by tightening bolts 21 relative to frame 22. A torque of 37 inch-lbs. on bolts 21, or the bolts used in adjustors A and/or brackets B is said to prevent implosion.
