Abstract

1,157,113. Oxygen tents. NATIONAL RESEARCH DEVELOPMENT CORP. 28 April, 1967 [29 April, 1966], No. 18854/66. Heading A5R. A flexible oxygen tent has a rear flap 5 for tucking under a mattress, superposed fringes 8, 9 along the front lower edge and is divided down the front to form two retractable flaps 6, 7 which have releasable fastenings 10, 11, 12. The fastenings comprise magnets 12 spaced along the edges of the front division and two interengageable tubes 10, 11 secured one to each front flap. The front flaps may be, :held in retracted position by filamentary hook and loop type fastening tapes 13. The tent is made from sheet polyvinyl chloride fixedly or detachably secured at the top to a rigid dome 2 which is supported by a post 3 fixed to the bed 4. A bifurcated oxygen supply tube has inlet ends (not shown) which are serrated and have internal sleeves and apertures along the sides to prevent the patient occluding them. The fringes 8, 9, comprise four superposed strips of polyvinyl chloride cheating, the lower three of which are cut transversely across half their width. 1,157,143. Antiviral compositions. E.I.

[Also in Division C2] Pharmaceutical and veterinary compositions comprise from 0.5 to 95% by weight of an antiviral compound of formula I in which either (a) R is -NH 2 or -NH 2 .HCl or (b) R is -NR 1 ,R 2 , -N(CH 2 ) n where n is 2 to 6, or -N=CHR 3 ; wherein R 1 is hydrogen; C 1-6 alkyl; C 1-4 alkyl monosubstitued by hydroxy, C 1-2 allkoxy, amino, C 1-4 alkylamino or di- (C 4-4 alkyl) amino; C 2-6 alkenyl; C 2-6 alkynyl; cyclopropyl; cyclopropylmethyl; cyclobutyl; or cyclobutylmethyl; R 2 is the same as R, or is Cl, Br -CHO, -CH 2 COOH, -CH 2 COOCH 3 or -CH 2 COOC 2 H 5 , with the proviso that both of R 1 and R 2 are not hydrogen and that when R 1 is alkynyl or alkenyl having the unsaturated bond in the 1-position, R 2 is C 1-6 alkyl or monosubstituted C 1-4 alkyl; and R 3 is an aliphatic or monosubstituted aliphatic radical where the substituent is aromatic or heterocyclic an aromatic radical or a heterocyclic radical, such radicals containing not more than 12 carbon atoms; or, in case (b), a non-toxic acid addition salt of such a compound; and from 99.5% to 5.0% by weight of non-toxic carrier for the said compound or salt. The pharmaceutical compositions can be administered orally or parenterally in the form of, tablets, capsules, powder packets, solutions suspensions or elixirs.
