Title: Necklace clasp with spring clip and pawl - has elongate housing fitted with clip which moves from locking to open position
IPC: A44C5/20
Filed: 1975-05-14
Abstract: The jewellry clasp comprises an elongate spring clip, which engages in an elongated housing with two catch positions for the clip so that in the first position the clip protrudes out from the housing and releases an insert slit for connecting one end of the necklace to an eyelet moulded onto the clip and in the second catch position the clip fits further into the housing so that the insert slit is then covered. When the clasp is manufactured the spring clip is inserted in the housing where it then remains and since the pawl which is moulded onto the clip does not protrude from the housing there is no danger of accidental opening. The last eyelet of the end of the chain or necklace can be welded on independently of the spring clip so that the latter is not subject to heat which could weaken its resilience.

Title: Fire-resistant material based on aluminium sulphate - produced by dissolving bauxite in sulphuric acid and opt phosphoric acid
IPC: C09K21/02
Filed: 1975-10-31
Abstract: Fire-resistant material based on aluminium sulphate is produced by dissolving bauxite (pref. contg. at least 10% Fe2O3) in H2SO4 (opt. with addition of 0-150 wt. % H3PO4, esp. 30-80 wt. % H3PO4) at an elevated temp.; and pouring the resulting hot hydrated melt onto a web or fleece contg. inorganic fibres (e.g. glass fibres) or organic fibres (e.g. polyester fibres rendered flame-resistant by addition of a phosphorus or antimony cpd.) to form a fire-resistant plate. When exposed to fire, the material is converted into a viscous, stable foam retarding the propagation of the fire. The cost is lower than that of materials made of water glass and Al2(SO4)3. Bauxite can be replaced, fully or partly, by calcined clay. The addition of H3PO4 improves the anti-flame properties and the workability of the material.
