Title: Improved method of and means for extinguishing fires
IPC: A62C3/06
Filed: 1931-04-10
Abstract: 380,102. Fire-extinguishing. MATHER & PLATT, Ltd. and BARCLAY, S. F., Park Works, Manchester. April 10, 1931, No. 10650. [Class 47 (ii).] Fires in inflammable liquids are extinguished by arranging a sprinkler system so that the sprayer jets effect such a concentrated bombardment of the whole of the burning surface liquid that the surface is broken up and emulsified to a non-inflammable aqueous emulsion. In one form, sprayer heads are mounted above the surface of a tank of benzine, and water under pressure is used. These heads direct jets upwards on to spreaders which deflect the water downwards in the form of finely divided jets to bombard the whole surface of the benzine. In the case of fuel oil, the sprayers may be immersed in the oil near the surface. The sprayer heads may be operated automatically, being controlled by one or more pilot automatic sprinklers of known type, or they may be hand operated. Any suitable emulsifying agent, such as gum arabic, may be added to the water. Steam may be used instead of water, or steam and water may be used together. Air or a gas under pressure may be utilized to assist the water to produce an emulsion, or this may be facilitated by mechanical means, such as revolving discs against which the jets impinge.

Abstract: 810,639. Overhead travelling cranes. KONINKLIJKE NEDERLANDSCHE HOOGOVENS EN STAALFABRIEKEN N.V. April 3, 1957 [April 4, 1956], No. 10910/57. Class 78 (4). In an overhead crane, such as a soaking-pit crane, in which a tong column 3 (Fig. 1) suspended from a trolley 1 is held against movement relatively to the trolley in one or more horizontal directions, the wheels of the trolley are mounted in structures which normally engage abutments on the trolley but can move downwardly out of engagement with the abutments so as to remain in contact with the rails 8 when the trolley is tipped as a result of lateral forces on the tong column. In the construction illustrated, each of four wheels 2 (Fig. 4) at the corners of the trolley 1 is carried in a frame 14 pivoted about an axle 15 and normally engaging an abutment 24 which may be resilient. If, however, the trolley is tipped by a lateral load on the tongs 4 (Fig. 1) springs 22 hold the wheels 2 in engagement with their track. A dashpot 23 is effective only during upward movement of the wheels. The wheels 2 may be driven through a gear 19 on the shaft 15 from a gear 18 on a shaft 17 extending across the trolley. Switches controlling a warning signal or controlling the tong mechanism may be operated by undue movement of the wheel frames 14 which may slide vertically instead of being pivoted. The spring 22 and dashpot 23 may be replaced by an hydraulic system combining spring action and damping action and including a buffer space common to all the wheel mountings.
