Title: Inflation equipment
IPC: B63C9/18
Filed: 1960-09-30
Abstract: 887,190. Compressed gas containers ; pipe couplings. SPECIALITIES DEVELOPMENT CORPORATION. Sept. 30, 1960 [Sept. 30, 1959], No. 33693/60. Classes 8(2) and 99(1). A device for disconnecting a source for supplying pressurized medium from a unit being supplied with the medium when the pressure of the medium supplied decreases to a predetermined value, comprises a first coupling member 11 adapted to be coupled to the source, a second coupling member 12 adapted to be attached to the unit being supplied with the medium, means 56 for latching the members against separation, and means responsive to the pressure of the source for placing the latch means in unlatching condition and holding the latch means latched when the pressure is high and for permitting the latch means to unlatch when the pressure falls below a predetermined pressure. As shown, the member 11 is mounted on a gas cylinder 10 over the neck 14 of which is disposed a frangible disc 19 supported against rupture by the head 30 of a member 27 screwed into an adjusting member 29. Balls 39 are positioned between the member 29 and a plug 36 to which is attached a lanyard 50, the plug being provided with longitudinal notches that cooperate with a spring finger 51 to prevent the plug from rotating due to vibration. A slot 44 in the rotatable plug mates with a projection 45 on the member 29 and to allow axial adjustment of the member. The member 12 includes a nipple 55 held within the member by the latch means 56, and a tubular manifold 57 provided with an annular surface 67. The latching means comprise balls 86 positioned between the lower end 76 of the nipple and a collet 85 having a number of spring fingers 95 each provided with a barb 96. In operation, an axial pull on the lanyard 50 allows the plug 36 to slide from the bore 22 of and separate from the member 11 so that the disc 19 ruptures, gas then passing to the bore 60 of the member 12 to act against the surface 67 and the bore 80 of the nipple, the manifold and nipple being forced as a unit downwardly until the barbs 96 are positioned under the flange 87 of a latch retainer 84. When the pressure of the gas falls to a predetermined value springs 89, 91 move the manifold and nipple away from the collet 85 so that the balls 86 disengage from the nipple end 76 to unlock the nipple from the manifold whereby the spring 91 causes separation of the nipple from the member 12. The device is applied to emergency radio equipment ejected from an aircraft, a balloon carrying an antenna being inflated through the nipple 55.

Title: Process for the manufacture of metal mercapto carboxylic acid esters
Filed: 1927-12-15
Abstract: 282,427. Schering-Kahlbaum Akt.- Ges. Dec. 16, 1926, [Convention date]. Samples furnished. Metal-mercapto carboxylic acid esters are prepared by treating an aliphatic or aromatic mercapto caboxylic ester with an oxide or salt of gold, silver, arsenic, antimony and bismuth, preferably in the presence of a solvent. The products, which dissolve in oils and other organic solvents, possess therapeutic properties. Examples are given of the interaction of bismuth oxide and thiosalicylic acid n-butyl ester and of antimony trioxide with thiosalicylic acid methyl ester, the components being heated in a stream of hydrogen or carbon dioxide until dissolution is effected; the same products may also be obtained bv reacting on the mercapto acid ester in ether solution with an ethereal solution of bismuth or antimony compounds, such as the bromide and iodide, which are soluble in organic solvents. The silver and gold mercapto acid esters are similarly obtained by treating a solution of a mercapto acid ester in an organic solvent with alcoholic silver nitrate or a solution of potassium auribromide in acetic ether. The Specification as open to inspection under Sect. 91 (3) (a) describes also the treatment of mercapto and esters of the heterocyclic series. This subject-matter does not appear in the Specification as accepted. Thiosalicyclic acid esters are produced either by esterifying thiosalicylic acid with an alcohol in known manner, or by first producing the diesters of dithiosalicylic acid and then reducing these with gentle reducing agents, such as aluminium amalgam, in an organic solvent.

Title: Improvements relating to ultrasonic testing
Inventor: FARLEY PATRICK GEORGE
IPC: G01N29/24
Filed: 1965-08-10
Abstract: 1,123,835. Couplings for conveying ultrasonic energy. BRITISH RAILWAYS BOARD. 5 Aug., 1966 [10 Aug., 1965], No. 34178/65. Heading H4J. An ultrasonic probe, for testing hollow bodies such as bored driving axles, has a crystal arrangement which produces a beam of elliptical cross-section, the face of the probe which is applied to the part to be tested being inclined at a small angle to the plane normal to the axis of the probe, the divergence being in the direction of the minor axis of the elliptical crosssection. The angle is small so that the minor axis of the elliptical cross-section is substantially radial with respect to the axle under test, Fig. 3 (not shown), in order to avoid reverberations, which mask the measurement, and to avoid directing a large proportion of the beam into the bearings of the axle. Fig. 2 shows a top view of the probe which comprises two oblong piezo-electric polarized ceramic crystals 1, 2 mounted on the back faces of two transparent plastics blocks 3, 4 mounted inside a brass ease. The front faces 6, 7 of the blocks are cut at an angle to the probe axis, Fig. 1 (not shown) which angle may be 7¢ degrees or whatever is suitable for the particular object under test. The side faces and crystal end of the blocks are silvered and springs 11 hold the crystal against the silvered block and electrically connect to connector sockets 8. Transducer performance is improved by air cavities 12 lined with p.v.c. insulation. Electrical screening by a cork strip 10 and aluminium foils divides the two parts of the probe and either crystal can be used as the transmitter or receiver.
