Title: Fire-retardant coating composition
Inventor: MASER PETER RUDOLPH
IPC: C09D5/18
Filed: 1958-03-05
Abstract: A fire retardant and protective coating composition comprises (1) an alkali catalysed phenol (or phenol derivative e.g. cresol)-urea-dicyandiamide-aldehyde resin, (2) starch, (3) a binding agent which may be additional starch or a polyvinyl alcohol or acetate emulsion and (4) at least 25% by weight, based on the total weight of the composition, of an inorganic ammonium salt capable of liberating ammonia at flame temperatures e.g. mono ammonium phosphate.  Further optional additives include (1) a melamine aldehyde resin, (2) a pigment e.g. titanium dioxide and (3) a pesticidal compound, to render the coating immune to attack by insects and fungi, e.g. phenyl mercuric chloride solubilised by making a 1% solution in pyridine and adding an alkyl-aryl sulphonate and an organic surface active agent e.g. a sulphonated fatty alcohol. Application of the composition to the surface to be coated, for example wood which may be untreated or painted, may be by brushing, dipping or roller coating methods. When the coated material is exposed to flame, the coating expands to form a voluminous, insulative mat connected to the material by way of pillars of coating; further exposure results in charring, which further enhances the insulative properties.ALSO:A fire-retardant and protective coating composition, which may also contain a pesticidal agent, comprises an alkali catalysed phenol (or phenol derivative, e.g. cresol)-urea-dicyandiamide-aldehyde resin, (2) starch, (3) a binding agent which may be additional starch or a polyvinyl alcohol or acetate emulsion and (4) at least 25% by weight, based on the total weight of the composition, of an inorganic ammonium salt, e.g. mono-ammonium phosphate.  The specific pesticidal agent, which renders the coating immune to attack by insects and fungi, is phenyl mercuric chloride solubillized by making a 1% solution in pyridine and adding an alkyl-aryl sulphonate and an organic surface-active agent, e.g. a sulphonated fatty alcohol.

Title: Improvement in and relating to a permanent magnet chuck or work holder
IPC: B23Q3/154
Filed: 1943-05-21
Abstract: 572,007. Magnetic chucks. SIMMONS, F. L. May 21, 1943, No. 8137. [Class 60] [Also in Group XXXV] In a magnetic chuck of the kind having a work-supporting plate 14, Figs. 1 and 2, oomprising two sets of alternately arranged polepieces 12, 13 of opposite polarity, and wherein the operating magnet or magnets 10, 11 may be disconnected from the polepieces to facilitate removal of the work-piece from the supporting plate, the effects of leakage flux, which would interfere with the removal of the work-piece, are reduced by the provision of one. or more non-magnetic slides, such as 40, 46 carrying magnetic blocks 42 which are arranged to bridge the sets of polepieces, as shown in Fig. 2, when the magnets are disconnected from the polepieces. When the chuck is operative, the blocks 42 register with the polepieces, as shown in Fig. 1, and polar ridges 18-all of the same polarity-on the upper surface of the magnets are in contact with the polepieces 12, the polepieces 13 being connected to polar ridges 19 of the opposite polarity on the lower face of the magnet through the side plates 15 and baseplate 16 of the chuck which are of magnetic material. The base-plate has ridges 27 corresponding with the ridges 19 and the grooves 28 between them are filled with Babbitt metal, as also are the spaces 26 surrounding the polepieces 13 which are of less depth than the polepieces 12. Disconnection of the magnet from the polepieces is effected by a crank 36, rotation of which through 180 degrees moves the magnets by means of an eccentric pin 33 and cam plate 30, into a position where the polar ridges 18, 19 register with the Babbitt metal-filled spaces 26, 28. The slides 40, 46 are operated by movement of the magnets through a lost-motion connection provided by lugs 43, 44 depending from the slides into one of the channels 20 between adjacent polar ridges 18 of the magnets. When the chuck is to be out of use for a time, the slide may be used as a keeper for the magnets by returning the crank through 90 degrees so-that the parts then occupy the positions shown in Fig. 3 and a closed magnetic circuit is formed. In a modified construction, the magnet structure comprises three spaced magnets arranged side by side with the upper surface of the outer magnets of opposite polarity to the central magnet, the side plates of the chuck being of non-magnetic material. In this construction, the magnets may be stationary and have flat upper and lower surfaces, connection and disconnection of the upper surfaces with the polepieces of the work-supporting plate being effected by a movable pole-plate arranged between the under surface of the work-supporting plate and the magnetic and non-magnetic sections. U.S.A. Specification 2,286,238 is referred to.
