Title: Aqueous emulsions of oil modified alkyd resins
Inventor: OSMOND DESMOND WILFRID JOHN
IPC: C09D167/08
Filed: 1952-07-02
Abstract: An emulsion paint comprises a dispersion of a soap of an air-drying oil-modified alkyd resin in an aqueous phase containing a protective colloid (e.g. casein or glue), the acid number of the alkyd before soap formation being at least 15 and the amount of base used in soap formation being such as to reduce the acid number by 15-35 units.  If the base is volatile, it may be added in excess to an alkyd of acid number 15-35, the excess base volatilizing from the paint film.  The alkyd preferably has a viscosity at 25 DEG  C. of 150-300 poises.  A vinyl polymer produced by emulsion polymerization, e.g. polyvinyl acetate, polystyrene or a butadiene styrene copolymer may be added to the emulsified alkyd, preferably in an amount of 15-45 per cent by weight of the alkyd.  Pigments or extenders may also be added, e.g. anatase or rutile titanium dioxide, lithophone, iron oxide, sienna, organophthalocyanine pigments, barytes, blance fixe or Paris white. In examples emulsion paints are made by mixing together (1) a glyceryl phthalate resin modified by a mixture of linseed and dehydrated castor oils (A.N. 23.8), excess ammonia solution, titanium dioxide, water and casein (solubilized with borax and preserved with NaF); (2) a linseed oil modified glyceryl isophthalate resin (A.N. 25) ammonia solution sufficient to neutralize the acidity of the resin, cobalt naphthenate in white spirit, water and casein (solubilized with NaOH and preserved with sodium pentachlorophenate; (3) a dehydrated castor oil modified glyceryl phthalate resin (A.N. 32), potassium hydroxide sufficient to reduce the A.N. to 15, mineral spirits, water, casein (solubilized with KOH and preserved with NaF), lithophone and blanc fixe; a glyceryl phthalate resin modified with a mixture of linseed and dehydrated castor oils (A.N. 23.8), triethanolamine sufficient to neutralize the acidity of the resin, lead naphthenate in white spirit, casein (solubilized with NaOH and preserved with NaF), water and titanium dioxide; (5) linseed fatty acid modified pentaerythritol phthalate resin (A.N. 24.7), excess ammonia solution, titanium dioxide, whiting, water, casein (solubilized with borax and preserved with NaF) and bentonite; (6) a glyceryl phthalate resin modified by a mixture of linseed and dehydrated castor oils (A.N. 23.8), triethanolamine sufficient to neutralize the acidity of the resin, lead naphthenate in white spirit, casein (solubilized with NaOH and stabilized with sodium pentachlorphenate), water and a plasticized polyvinyl acetate emulsion.

A shell fuze is armed after discharge and during trajection of the shell, at first mechanically and then electrically, when a shaft 5 is rotated by reduction gearing and a spline shaft journal, connected to a radial air turbine in the nose of the shell, the rotation of the shaft 5 causing a nut 16 to move along a coarse thread 14 against a spring 24 to withdraw a fork-shaped part of the nut 15a out of corresponding bores in a shutter 10 after a predetermined period. The shutter 10 is then rotated by a spring 20 through 180 degrees to align a relay charge 12 with an electric detonator 11 and a booster (13, Fig. 1, not shown). During the continued rotation of the shaft 5, a fine thread 6 on the shaft is disengaged from a corresponding thread in a stationary member 7 and the spring 24 urges the shaft 5 and nut 16 inwardly, whereby the shaft 5 is disengaged from the spline shaft journal and the shutter is locked in the armed position by the fork 15. Meanwhile a locking pin 28, Fig. 4, locking one end of a radial spring 26, which is in engagement at its other end with a contact pin 27 on the detonator 11, is forced by spring means into a bore in the shutter 10 when the shutter is in the armed position, and releases the spring 26 for temporary engagement against a stud 28a on the fork (15) as the nut 16 and shaft 5 are moved inwardly by the spring 24, the spring 26 is again released and engages a contact pin 29. An impulse from an electronic device receiving electrical energy from a generator driven by the turbine then initiates the explosive charge of the shell. The turbine and generator are protected during storage and transport of the shell by means of a rubber hood (31) over the nose of the shell.
