IPC: H01T13/32
Filed: 1927-10-05
Abstract: 303,549. Halford, R. G. L. Oct. 5, 1927. Sparking-plugs.-The end of the casing has an opening sufficient only for leaving the necessary spark gap around the central conductor and is cut as a helix 18 of rather more than a single turn. In addition the exposed surface is concave. The end 20 is tangential to a circle of larger diameter than the conductor 16. According to a modification the casing terminal may be in the form of one or more wires 26 coiled around the central electrode at a distance equal to the spark gap. The ends of these wires project slightly beyond the conductor 16 and are obliquely cut to present an obtuse-angled edge 28.

Patent GB-1071419-A (GB)
Title: Apparatus for withdrawing a surface layer from liquids
Inventor: WEMYSS WILLIAM ALEXANDER
IPC: B01D35/05
Filed: 1963-07-05
Abstract: A hollow member closed at the bottom is disposed below the surface of a body of liquid (e.g. in a swimming bath) in consequence of which it fills with liquid, and a float member within it rises until its upper edge is above the level of the body of liquid.  When suction is applied to a pipe at the bottom of the hollow member, the float member sinks until more liquid enters the hollow member by passing over the lip of the float and flowing down a passage within it; the flowing liquid carries debris with it.  The debris collects on a loose plate spaced from the bottom of the hollow member, the liquid passing inwards through a hollow cylindrical filter element secured to the plate and passing downwards through a hole in the plate to the suction pipe.  In another embodiment the plate is replaced by a cup. In both cases the float member is preferably a sliding fit in the hollow member.

Title: Preparation of polyurethane dispersions
Inventor: KEBERLE WOLFGANG
IPC: C08G18/08
Filed: 1966-06-16
Abstract: 1,125,227. Polyurethane dispersions. FARBENFABRIKEN BAYER A.G. 16 June, 1966 [18 June, 1965], No. 26982/66. Heading C3R. Self cross-linking aqueous dispersions or aqueous colloidal solutions of polyurethanes are prepared by (a) reacting a polyhydroxy compound having a M.W. of 300 to 20,000, a polyisocyanate and, if desired, a chain-lengthening agent containing reactive hydrogen atoms, (b) incorporating into the polymer or polymerforming components, at any convenient stage, one or more polar compounds which will impart to the polyurethane a salt-like character, (c) incorporating into the polymer or polymerforming components, at any convenient stage, one or more alkoxymethylisocyanates or alkoxymethylisothiocyanates under conditions which do not favour the development of a cross-linking action by the alkoxymethyl groups, (d) adding water to form a solution or dispersion, and at least partly removing any organic solvent present. The polyhydroxyl compounds, e.g. polyesters, polyesteramides and polyethers, polyisocyanates and chain-lengthening agents are those conventionally used in the polyurethane art. Preferred alkoxymethylisocyanates are methoxymethyl-, ethoxymethyl- and isopropoxymethyl - isocyanate. The alkoxymethyliso(thio)-cyanates and the compounds which impart a salt-like character to the polyurethane are incorporated by the one-shot or prepolymer processes. The polyurethanes may, however, be converted into the salt-form in an organic solution and then reacted with the alkoxymethyliso(thio)cyanates. Compounds which impart a salt-like character to the polyurethane are those such as N-methyldiethanolamine, N- cyclohexyldiisopropanolamine, γ,γ<SP>1</SP>-bis-aminopropylmethylamine and thiodiglycol. Salt formation is then carried out using e.g. alkylating agents or acids. Cross-linking takes place simply by drying, by lowering the pH value of the dispersion or by heating. Cross-linking is avoided during the incorporation of the alkoxymethyliso(thio)cyanates by preferably maintaining the temperature below 80 C., carrying out the reaction in an inert organic solvent or by maintaining a neutral to slightly basic reaction.
