No. 25374.—23rd December, 1908.—AVILA THOMAS, of 99 Hancock Avenue West, Detroit, Michigan, United States of America, Engineer. Improvements in reinforcing-bar for concrete structures.

Extract from Specification.—The primary object of the invention is to provide simple and efficient means whereby a cementitious mass or body capable or resisting high compression, but naturally deficient in tensile strength, may be so reinforced as to enable it to successfully resist all the tensile and shearing strains to which it may be subjected. The invention further contemplates the construction of a reinforcing-bar for concrete structures, consisting of a main tension member and minor shear members, said parts being so constructed as to enable the shear members to be associated with the tension member at any desired angle thereto, and at any desired point, and securely attached to said bar. The invention further contemplates means for effecting a connection between the tension member and the oblique shear members, of such a character as to enable the shear members to be readily associated with the tension member, and, when properly positioned, securely locked thereto.

[NOTE.—The above extract from the specification is inserted in place of the claims.]

A cylinder-lubricant for internal-combustion engines, produced by saponifying an animal or a vegetable oil with caustic potash or sodium, dissolving the soap in water, and treating the solution to neutralise excess of free alkali, substantially as described. (3.) A cylinder-lubricant for internal-combustion engines, produced by dissolving commercial soft-soap in water, and treating the solution with hydrochloric acid to neutralise excess of free alkali.

(Specification, 2s. 6d.)

No. 25382.—24th December, 1908.—SAMUEL EWING, of Brooklyn Street, Burwood, New South Wales, Australia, Commercial Traveller. An improved apparatus for generating fire-extinguishing gases and automatically ejecting a stream of water permeated therewith.

In an improved apparatus for generating carbonic acid or other fire-extinguishing gases and automatically ejecting a stream of water permeated therewith, a jar hung on trunnions, and designed to be inverted by means of an externally operated mechanism so as to deposit its chemical contents into a reservoir of water, for the purpose set forth, and substantially as described, and as illustrated in the drawings. (2.) In an improved apparatus for generating fire-extinguishing gases, a receptacle containing the required chemical substance designed to be inverted at will, and an externally operated means for accomplishing same, in combination with a water-tank of suitable construction, the necessary opening in which is closed by an airtight lid, for the purpose set forth. (3.) In an improved apparatus for generating fire-extinguishing gases and automatically ejecting a stream of water permeated therewith, a receptacle such as 20, having trunnions such as 19, one of which carries a cog-wheel such as 21, in combination with a rack such as 22 engaging with said cog, said rack being provided on a lever such as 25, passing through a stuffing-box such as 24, provided in the lid of the vessel containing said receptacle and the water, as and for the purposes as set forth, and as illustrated in the drawings. (4.)
