Title: Improvements in and relating to elastic fluid turbines
IPC: F01D25/28
Filed: 1936-02-11
Abstract: 448,402. Steam turbines. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. Feb. 11, 1936, No. 4131. Convention date, Feb. 12, 1935. [Class 110 (iii)] Means are provided for taking care of the expansion of the turbine casing due to heating during operation. The turbine is of the double flow type and comprises a cowl 5 and an exhaust casing 6 formed of welded sections.

Title: Improvements in and relating to machines for filling receptacles with liquids
IPC: B67C3/26
Filed: 1938-02-10
Abstract: 510,958. Bottling. BROADHURST, S. F., and ALBRO FILLERS & ENGINEERING CO., Ltd. Feb. 10, 1938, No. 4197. [Class 125 (ii)] Relates to machines for exhausting air from a receptacle, such as a milk bottle, and thereby causing liquid to flow into it from a reservoir, the exhausting pipe comprising a chamber for intercepting any liquid sucked therein, which liquid falls down a drain pipe back to the reservoir; the machines having a plurality of filling heads and continually dispensing liquid to at least one receptacle, while in use. According to the invention, the supply of liquid to the reservoir is so effected as to produce, during the normal operation of the machine, a continuous injector action upon the liquid in the drain pipe to assist in feeding the liquid back to the reservoir. Fig. 2 shows a rotary machine in which the drain pipe 19 surrounds a pipe 21 through which liquid is supplied to the reservoir 15. During running of the machine the float controlled valve 25 is always open, a continuous injector action resulting. On excessive evacuation of the interceptor 16 a bell-floatcontrolled sleeve 27 shuts off the vacuum supply pipe 18. An opening 27a equalizes pressure inside and outside the tube 27. In a modification, Fig. 4, the reservoir and interceptor are stationary and communicate by pipes 14c, 17c with manifolds 14a, 17a, the filling heads rotating about the axis A-A. A stationary plate valve 30 closes suction pipes 17 leading to filling heads with which no bottles are engaged.

Title: An improved joint-locking member primarily for aircraft wing root joints
IPC: B64C3/00

Abstract: 565,867. Bush extractors. GENERAL AIRCRAFT, Ltd., CROCOMBE, F. F., and TEGERDINE, G. E. March 16, 1943, No. 4296. [Class 61 (iii)] [Also in Groups XXII, XXV and XXXIII] A bolt, used particularly in aircraft wing root joints, is so constructed that it serves, in addition to securing the joint, as inserter and extractor for bushes forming a part thereof. The wing parts are formed with plates or straps 1, 2 connected by a bolt 8 with an interposed distance-piece 4. Bushes 9 are a force fit in the plates. The bolt has an enlarged centre part 7 threaded to engage the distance-piece To assemble the joint, the distance-piece is placed in position and one bush 9 is placed on the bolt and backed up by a nut 10. The bolt is then screwed into the distance-piece by means of its squared end 11. When the bush has been forced in sufficiently to seat the flange 12, the nut 10 is removed and the bolt screwed through the distance-piece and removed on the other side. The other bush is then inserted in a similar manner. The nut 10 is eased off, if necessary, the bolt is centred in the distancepiece and the joint finally locked by tightening the nuts 10 at both sides. To remove the bushes, the nuts 10 are removed and the bolt screwed first in one direction and then in the other so that the enlarged centre portion contacts the ends of the bushes. In a modification, separate set-screws are used at opposite sides of the joint and recesses between the threaded and plain portions receive circlips to effect removal of the bushes. The threads on the set-screws are of opposite hands and final tightening may be effected by turning the distance-piece.
