OBITUARY. The death is announced of Mr. Alfred Philip Steeds, a director of the Rhondda and Swansea Bay Railway Company. The death has occurred of Viscount Ingestre. Deceased was a director of the Earl of Shrewsbury’s Brereton Collieries Limited. Mr. Thomas Lynch, president of the H. C. Frick Coke Company, has just died at Greensburg, Pa., at the age of 60. Mr. G. Felton, who died recently at Low Fell, was a mine worker from boyhood. He served as back-overman at Bebside, under-manager at Allerdene Colliery and under-manager at Shilbottle. He retired in 1909. Death took place at the age of 66 years. Returns issued by Lloyd’s Register show that, excluding warships, 462 vessels of 1,627,316 tons gross were under construction in the United Kingdom at the end of last year. The tonnage is about 96,000 tons less than under construc- tion at the end of September, and about 329,000 tons less than building a year ago. The highest figure ever reached was 2,050,000 tons at the end of the first quarter of 1913. Only vessels of 100 tons and upwards, the construction of which has actually begun, are included in the calculations. ABSTRACTS OF PATENT SPECIFICATIONS RECENTLY ACCEPTED. 939 (1914). Improvements in Pneumatic Drills. Saxby and Farmer Limited, and F. C. Brittain, all of 53, Victoria - street, Westminster, London.—Relates to improvements in pneumatic drills, and is more particularly applicable to that type of drill known as a corner drill for use in awkward places. The invention consists essentially in means whereby the special pawl shaft usually employed between the crank shaft and the drill is dispensed with, thus simplifying and cheapening the construction of the drill. Fig. 1 is a sectional elevation of a drill constructed according to the invention; fig. 2 is a plan of same; fig. 3 is a section on line X—X of fig. 1. In operation the drill is placed in position, air or water is admitted below the piston, forcing it out against the stop or resistance, and subsequently pressing the drill for- ward into the material to be bored. When it is desired to combine hand and automatic feed, as shown, a hand feed screw M may be arranged in the piston or piston rod j, which thus forms the feed nut, and a suitable catch or stop is provided to lock the piston in the inner position. Where desired, a small hydraulic ram may be attached to the apparatus to supply increased pressure if the pressure in the main is not sufficient to feed the drill forward. The pressure on the drill may be controlled by a suitable valve. (Six claims.) 2650 (1914). Improved Process and Arrangement of Plant for the Treatment and Recovery of Tar and Ammonia Liquor from Producer or other Gas. Q. Moore, of Garrowbank House, Riddrie, Glasgow, and the Dowson and Mason Gas Plant Company Limited, of Alma Works, Levenshulme, Manchester, Lancashire.—According to the invention, the gas leaving the producer or retorts is led into one or more air- or water-cooled condensers, wherein its temperature is reduced to a temperature most suitable for the extraction of the tar—this temperature ranging between about 100 and 160 degs. Fahr., in accordance with the quality of the tar present. From the condenser chest or chests the gas passes to any convenient form of tar extractor which is arranged at such a higher level than the chests of the condensers that tar and water of condensation from the extractor may flow back to the chests as hereinafter explained. The gas after leaving the tar extractor may either be further cooled to atmospheric temperature in any convenient form of con- denser previous to being treated by the water of condensa- tion from the condenser chests for the extraction of the ammonia, this water of condensation being first cooled as hereinafter explained, or the ammonia may first be extracted in an acid bath and the gas then cooled. The tar and the condensed steam, after reaching the condenser chests from the tar extractor, flow back therethrough to an exit near the entrance for the gases. In the course of passing through F/C i. (3 L JI 'Z3 J! HZ G2 a \DI J2 the chests in a direction contrary to the flow of the gases, the tar which is partially suspended in a globular form in water comes into contact with the hot gases. It is thereby so thoroughly heated that dehydration takes place, whilst the light and heavy tars are thoroughly mixed, and a tar of uniform consistency obtained. The tar and the virgin
