Title: Anti-virus prepns derived from amino- - guanidine
IPC: A01N47/44
Filed: 1970-06-16
Abstract: Prepn. contain a compound (or one of its salts) of formula: (in which R1, R2, R3 and R4 are H, subst. or unsubst. hydrocarbon (alkyl or aryl) gps. or amino gps. and, in addition R1 and R2 with their neighbouring N atom form a heterocyclic gp. Q is either an amino gp. of the formula: NR5R6, in which R5 and R6 are as R1 and R2 above, or an imino gp. of the formula: N=CR7R8, in which R7 and R8 are H, subst. or unsubst. hydrocarbon gps. (alkyl or aryl) or heterocyclic gps.). Many variants of this class of compound have been prepared but two of the most effective anti-virus agents are: (CH3)2N-C(:NH)NHNH2 and CH3NHC(:NH)NHNH2. These cpds. can be used in the form of solutions, emulsions, dispersions, sprays, dusts, etc. with suitable inert diluents or carriers. Pot tests on tomato, cucumber, tobacco and cane sugar plants impregnated with common plant viruses showed cpds. (A) and (B) to be highly effective.

Title: Flexible container - by folding/welding plastic sheet and fastening rigid plastic strips to welded part
IPC: B65D88/16
Filed: 1971-06-24
Abstract: Flexible container is produced from a heat sealable plastic sheet by closing the sheet on itself and welding to define a cylindrical cover, and folding and welding the edges around the cover. In each of the corners a single flat weld is effected on the whole of the stacked thicknesses of the sheet to define a flat lip in which the layers have a tendency to move apart when the container is placed under pressure. At least one hole is drilled in the thickness of this lip and two rigid strips with holes are placed on the opposite sides of the lip and a fastener is inserted through the openings to unite the stacked parts.

Title: Synchronisation control for photocopier - has movable original size indicator on flat bed and monitors in path of copy
IPC: G03G15/28
Filed: 1973-11-15
Abstract: The original is placed on a flat bed table which reciprocates over the fixed optical system.

Title: Finger bar mower drive mechanism - uses straight belt drive between drive pulley and pulley on mid point of T-rod
IPC: A01D34/30
Filed: 1975-07-01
Abstract: The drive is made to rock a cranked rod (13), cranked near (14) to and fro about the longer of its end-sections as axis; the farther end of the shorter end-section is thus moved to and fro in an arc; this moves the mower blade (14). The longer end of the rocked (cranked) rod terminates in a stirrup (16), which is spanned by the cross-bar of a T-shaped rod (17) whose other end is attached to the periphery of a driven pulley (6) by a ball bearing (18, coaxial with 17, oblique to 6): the axis of the pulley passes through the mid-point of the cross-bar of the T. As the pulley rotates, the upright of the T generates a cone, and its cross-bar rocks the stirrup (16) and so the cranked rod (13). The driven pulley (6) is coplanar with its driving pulley (8); this avoids the use of the idler pulleys usually needed to deflect the belt drive.

Title: Desalination using reverse osmosis hollow fibre module - produces drinking water from automatically sequenced installation on ship
IPC: C02F1/44
Filed: 1976-01-22
Abstract: A process and a plant installation for producing drinking water by the desalination of sea water. The system is of the type in which sea water is pre-filtered in a low pressure (L.P) circuit and then pumped at high pressure (H.P) to a reverse osmosis module comprising semipermeable hollow fibres. The complete process comprises the following essentials: (a) fine filtration, pref. to about 5 mu in the L.P circuit. (b) at the start of each process run. The H.P circuit is flushed out by running product water to waste for a brief period; at the same time the L.P. circuit up to the prefilter inlet is pumped thro. with sea water (c) at the end of each run, the H.P circuit is thoroughly rinsed with pre-processed drinking water so that no sea water is left in the module (d) periodic regeneration of the H.P. circuit by flushing with a soln. contg. e.g. detergents, descaling agents. The sequence of operations is followed automatically apart from start up and regeneration. Used for prod. of drinking water from sea water. The installation is partic. suitable for sea-going vessels. Start up flushing of the H.P. circuit removes residual rinse water which is a source of bacteria. Rinsing the module at the end of each run prolongs its useful life.
