Title: Improvements in or relating to the manufacture of foamed isocyanate reaction products
Inventor: MARKLOW RAYMOND JOSEPH
IPC: C08G18/64
Filed: 1964-06-29
Abstract: Foamed isocyanate reaction products are prepared by reacting a simple organic polyisocyanate (i.e. a monomeric polyisocyanate, its uretdione or isocyanurate polymer or a phosgenation product of a fomaldehyde-polyamine reaction product) with pitch or tar and causing a foam-forming gas to be formed.  Other reactants, e.g. polyethers, polyesters or polyesteramides may be included in the reaction mixture.  The tar or pitch may be derived from wood, peat, shale, bones, vegetable wastes and coal.  In Example (1) coke oven tar pitch, crude diphenylmethane diisocyanate and tris-(b -chloroethyl) phosphate were heated together. Stannous octoate, siloxane, oxyalkylene copolymer, and water were added and the mixture allowed to form a foam.  In Example (2) a foam was produced from the same reactants but by the " one shot " method.

Abstract: 1,125,208. Winches; transferring loads to and from aircraft. BOEING CO. 21 June, 1967 [20 June, 1966], No. 27005/67. Headings B8B and B8E. A cargo handling system for transferring a cargo 16 between a helicopter 10 and the deck of a ship, comprises a constant tension winch 13 in the helicopter, exerting a lifting force on a cargo harness 15 in excess of the weight of the cargo, and a constant rate winch 18 on the deck, exerting a lowering force on the cargo in excess of the said lifting force, whereupon the cargo 16 descends steadily. Any slack developing in the cables 12, 17 connecting the cargo and winches, due to relative movements of the helicopter and ship, is automatically taken up by the constant tension winch 13. The latter is driven from a motor, through a torque converter and reduction gearing, the torque converter slipping once a pre-set torque for the winch has been exceeded. A fail safe brake associated with the winch 13 prevents free reeling out and sudden rewinding when the cargo is removed. The cable 17, between the deck winch 18 and cargo 16, passes around a pulley 19 secured to the deck, for cargo positioning purposes. The cargo may be raised from the deck to the helicopter by the reverse operation of the winches. The system may be associated with any airborne platform and other surface vertically spaced therefrom.

Title: Business forms
IPC: B41L1/26
Filed: 1977-06-29
Abstract: 1534844 Manifolding MOORE BUSINESS FORMS Ltd 29 June 1977 [2 July 1976] 27197/77 Heading B6A A business form consists of a sheet folded inwardly in three, in such a way that the underside of an upper folded leaf 15 overlies the upper side of a lower folded leaf 17 and both overlie an initially-central panel 16, so that a uniform front receptor coating CF on one face of the sheet and a uniform back donor coating CB on the other face come into contact only where leaf 15 overlies leaf 17. Consequently pen or typewriter pressure to make a mark 31 on the front of leaf 15 produces a corresponding mark 29 on the front of leaf 17, as the initially-colourless coatings CF, CB react, but has no effect on panel 16. The upper leaf 15 may be separable along a line of perforations 18, so that it can be divided into a record portion and a residual flap bearing glue 21, so that it can be used to seal the envelope formed by adherence of the leaf 17 and section 16 along glue lines 26. Alternatively the upper leaf may be longer than the lower one and have section folded back to receive the mark 31, so that the upper leaf, less the folded back portion, is available as a closing flap which can completely cover leaf 17. Preferably the forms have a CB coating comprising a liquid in pressure-rupturable microcapsules and a CF coating in solid form. The forms may be portions of a longitudinally-folded web, divided into sections by cross perforations and provided with feed perforations adjacent the folds 13, 14, in strips which are detachable along lines of weakening to separate the leaves 15, 17 and panel 16 for use as independent sheets.
