The cationic group may be primary, secondary or tertiary amino quaternary ammonium sulphonium or phosphonium, and such groups are introduced, e.g. by etherification with appropriate epoxy- or chloro-compounds. The anionic group may be carboxyl, sulphonate, sulphate or phosphate, and may be introduced as follows:-Carboxyl by reaction with (a) monohalogen fatty acids, (b) anhydrides, e.g. of maleic, succinic or citraconic acids, (c) Me and Et esters of acrylic, crotonic or itaconic acids, (d) acrylonitrile followed by hydrolysis of the CN groups or (e) Na periodate followed by NaClO 2 to convert the C=O groups to COOH. Sulphate by reaction with tertiary amine/SO 2 adducts or by sulphamic acid and/or sulphuric acid-urea treatment. Sulphonate by reaction with (a) sultones, (b) the Na salt of haloalkane sulphonic acids, oxypropane or epoxypropane sulphonic acid, or ethylene sulphonic acid or (c) Na periodate followed by treatment with a bisulphite.

Title: Improvements relating to Structural Units.
IPC: E04C2/20
Filed: 1967-05-03
Abstract: A structural unit, e.g. for use in walls or partitions, comprises one or more sheets formed of molecularly oriented organic continuous filaments arranged at random in a non-parallel manner throughout the or each sheet, the sheet or sheets being impregnated with a thermosetting resin. The filaments may be of polyethylene terephthalate, isotactic polypropylene, polycaproamide, polyhexamethylene adipamide, PVC, polyvinylidene chloride, cellulose acetate, polyacrylonitrile or polyvinyl alcohol and the impregnating resin may be a phenoplast or aminoplast. In one method of making the sheets, polyethylene terephthalate is extruded as filaments from a spinneret and advanced by means of a drawing injector nozzle supplied with compressed air, the filaments being cooled during such advance. The bundle of filaments so formed is fed via a reciprocating guide on to a conveyer belt to form a non- woven sheet, which sheet is passed between heated calender rolls to bond the filaments where they cross. Two sheets formed as described, i.e. " spunbonded," are superposed and needled before impregnation with a solution of phenolformaldehyde resin in a mixture of alcohols. The impregnated sheet is allowed to dry, then dried under heat at one temperature before heating at a higher temperature to cure the resin. The resulting sheets are sound insulating, rot resistant and fireproof. In a second embodiment a structural unit comprises a core of rigid polyurethane foamed in situ between two of the impregnated sheets. An alternative unit comprises an undulating one of said sheets between two plane said sheets.

Title: Boost regulator with high voltage protection
IPC: H04N3/16
Filed: 1975-01-31
Abstract: A bosted B+ regulator in a horizontal deflection system comprises a controlled rectifier coupled to a winding in the deflection system for rectifying voltage generated therein and adding it to the line-rectified voltage for providing a constant boost voltage for operation of the deflection system in the presence of line voltage fluctuations. A zener diode is coupled between the rectified line voltage and the rectified boost voltage and to a control electrode of a switching device such as an SCR. Normal deflection system starting current is coupled through a junction of the SCR and through the zener diode in the forward direction. When the boost voltage exceeds a predetermined level, the zener diode breaks down, causing the SCR to conduct which in turn provides a short circuit across the rectifier and its associated winding for disabling operation of the deflection system.
