Abstract: Aqueous alkali-soluble polymers are prepared by interpolymerizing, in the presence of a peroxide catalyst, maleic anhydride and an unsaturated compound containing a methylene group attached by a double bond to a carbon atom which is in turn attached only to atoms selected from the group comprising hydrogen and carbon having each valency bond attached to different but not necessarily dissimilar atoms.  Suitable substances for interpolymerization with maleic anhydride are ethylene, propylene, isobutylene, 1-butene, 1-pentene, 1-hexene, 3-methyl butene-1, di-isobutylene, 2,4,4, trimethyl-pentene-1, methylene cyclohexane, vinyl cyclohexane, D ,5,6, hexenonitrile, allyl and methallyl esters, e.g. allyl acetate, methallyl acetate, allyl benzoate, allyl and methallyl amides, e.g. N-allyl acetanilide and N-methallyl acetamide, allyl methyl ketone, allyl phenyl ether, methallyl phenyl ether, and acetals of acrolein or methacrolein. The process may be operated at a temperature as low as 40 DEG  C. Preferably, the temperature lies between 70 DEG  C. and 150 DEG  C. Superatmospheric pressure may be employed.  The reaction may be carried out in a closed vessel or in an open vessel with a reflux condenser.  An inert solvent, such as xylene, benzene, toluene, dioxane, acetone, cyclohexane or saturated petroleum hydrocarbons may be present.  When using an olefine it should preferably be present in excess.  Suitable peroxide catalysts are benzoyl peroxide, acetyl, butyryl, lauroyl, or succinyl peroxide or ascaridole.  The catalyst is preferably present to an extent of .5 to 5 per cent.  It may be added slowly to the reaction mixture throughout the reaction periods.  Modifying agents or third components of the interpolymer may be present, e.g. a polymerizable vinyl or vinylidene compound, such as styrene or methyl methacrylate. The polymers are useful as tanning agents, photographic chemicals, gelatin substitutes, textile assistants, protein hardeners and alkyd resin ingredients.  The interpolymers of maleic anhydride and ethylene are soluble in water without addition of alkali.  Examples describe the interpolymerization of diisobutylene and maleic anhydride, of diisobutylene, maleic anhydride and styrene, of maleic anhydride and methylene cyclohexane, of maleic anhydride and allyl acetate, of maleic anhydride and ethylene, of maleic anhydride and propylene and of maleic anhydride and isobutylene.

Abstract: 935,372. Electric selective signalling systems. SKIATRON ELECTRONICS & TELEVISION CORPORATION. Dec. 16, 1959 [Dec. 17, 1958], No. 12957/60. Divided out of 935,371. Class 40(1). A field station (or transponder) for the subscription television system described in Specification 935,371, which is referred to, recognizes a particular combination of five serially received difference frequencies on a line 670, Fig. 2, and as a result applies a reply signal of frequency f1 or f2 to line 670 depending upon whether a switch 674 is in its position X or Y or, if switch 674 is in some other position no reply signal is applied to line 670. The incoming signal on line 670 on which the five frequencies are amplitude modulated is amplified 676, demodulated 706 and the five frequencies are recognized by five tuned circuits 708, which, if the appropriate five frequencies are received, causes, via pulse stretchers 720, demand gate 734 to open and energize a reply 758. This changes over a contact 766 whereupon tube 706 with the tuned circuits 708 and a transformer 717 operate as an oscillator, its frequency depending upon the position of switch 674. If switch 674 is in position X, its ganged wiper 788 earths a capacitor 786 producing a frequency f1. Position Y of the switch produces a frequency f2. When the switch is in any other position a third ganged wiper 764 prevents the relay 758 ever being energized and so no oscillation is produced.
