Title: Improvements in or relating to the production of halo-substituted dienes
IPC: C07C17/00
Filed: 1962-03-05
Abstract: 2,3-Dihalobutadiene-1,3 is prepared by contacting 1,4-dihalobutyne-2, at a temperature of 20 to 150 DEG C. with a liquid mixture comprising one or both cuprous chloride and bromide and a solubilizing agent or a mixture of such agents which yield bromide or chloride ions in the medium. Solubilizing agents may be hydrogen, ammonium, alkali metal or alkaline earth metal chloride or bromide or an aliphatic primary or secondary amine hydrochloride or hydrobromide. An organic solvent e.g. N,N-dimethylbenzamide and N,N-diethyl-benzenesulphonamide may be the reaction medium. The 1,4-dihalobutyne-2 may be prepared from 2-butynediol-1,4 by reaction with a carbonyl halide and decomposing the bishaloformate produced, or by reaction with phosphorus trihalide, or by reacting under strongly acidic conditions at 60 DEG to 150 DEG C. with the cuprous halide mixture above.

Title: Improvements in or relating to an installation for effecting the stability of ships
IPC: B63B39/03
Filed: 1937-03-23
Abstract: 492,448. Stabilizing ships. SIEMENS APPARATE UND MASCHINEN GES. March 23, 1937, Nos. 8565, 8566, and 8567. Convention dates, March 31, 1936, May 15, 1936, and June 22, 1936. [Class 113 (i)] An anti-rolling tank installation for controlling the stability of ships is arranged so that the free surfaces of the liquid in the tanks can be cut out, thus affording the possibility of reducing or increasing the metacentric height according to whether the installation is operated with or without free surface. The crosssection of the conduit 9 connecting the tanks 6, 7 is made so large that when the cut-off valve 10 is fully open, free-surface conditions of flow obtain. With the valve 10 partially or wholly closed, the system acts as an ordinary damping-tank installation. The possibility of varying further the metacentric height is enlarged by employing a gang of tanks. The change from free surface to controlled conditions in the tanks may be automatically ensured by the employment of valves 38, 39, Fig. 5, floating on the free surfaces of the liquid in the tanks and controlling the exits of the air conduit 34. Similar valves are in another modification operated by an angle-of-roll indicator. In other modifications, flat tanks 60, Fig. 8, are employed. The inclination of the tops 61, 62 is so arranged that at a predetermined angle of roll, the liquid comes into contact with one tank cover, thus eliminating the free surface. Plates 65 damp the motion of the water. In this type of installation, the double-bottom may be employed as a tank, the longitudinal girders being bored at an angle corresponding to the angle of the tank top in the case of the installation referred to above. Specification 458,616 is referred to.

Abstract: 756,340. Locking nuts. FORGAARD, H. L. July 1, 1954 [April 2, 1953], No. 9127/53. Class 89(1). A lock-nut comprises a body 10, Fig. 2, having a non-threaded bore, of diameter smallest at the middle and increasing outwardly therefrom, to receive a cylindrical bush 11 having slits 11b and expanded to engage the wall of the bore, the bush being finally drilled and tapped. The ends of the bush are dished as at 11c and either the body or the bush or both are serrated as at 10c, Fig. 8, to prevent relative rotation. The exterior of the body may be square, hexagonal, or circular with ribs or tommy-bar holes. When screwed on a bolt &c. against an abutment, the bush is moved relatively to the body and towards the abutment. Thus the part of the bush adjacent the abutment is deformed and pressed against the bolt threads while the remote part is drawn towards the centre of the body and hence compressed on to the bolt to thereby lock the nut on the bolt.

Class 38(v) The trifurcated spring blade snap-action switch of the parent specification is modified so that successive operations of a push button 3 or other member in the same direction move the actuating member 5 carrying the spring blade 1, 2, in opposite directions to effect the operation of the switch. In the Figure the hollow push button 3 is upwardly biased by a spring 22 and carries a rocking lever 9, which when the push button is depressed, engages in a groove 16 or 17 in the actuating member 5 and turns the actuating member from one limit position to the other to snap the blade spring through its dead-centre position. The turning of the actuating member moves the ridge 18 between the grooves 16, 17 from one side to the other of the central axis of the lever 9, which on the release of the push-button 3 is centralized by a V-guide 23, so that on the next depression of the push button, the lever 9 engages in the other groove 16 or 17 to turn the actuating member back to its initial limit position. Reference is made to operation of the switch by pulling a chain.

Abstract: 682,446. Valve accessories. LANGHAM, A. J. July 5, 1950 [April 5, 1949], No. 9296/49. Class 135. A valve for controlling the flow of fluid through a duct, e.g. compressed air from an impeller to furnace burner, comprises at least one butterfly valve of which the valve plate is formed in at least two sections adjustable relatively to each other in a plane containing the axis of rotation of the plate, and in which the superficial operative area of the valve plate is variable at will. As shown, a rectangular frame 2, Figs. 1, 2, forming part of a duct 3, 4, mounts a horizontal spindle 1 having a slot 6 in which are inserted plates 8, 9 having apertures 24 and constituting the valve plate. The plates 8, 9 have slots 10 engageable with a screw 11 and tongues 12, 13 to permit of their adjustment relatively to each other along the axis of the spindle from outside the duct. A setscrew 17 and a bush 16 lock the plates in their transversely adjusted position, whilst a quadrant 19, Fig. 3, having an arcuate slot 20 engageable with a stud 21 locks the valve plate after rotation of the spindle to any desired position. In a modification, a further apertured plate is secured to the spindle and the spindle itself is arranged to be adjustable longitudinally. In this arrangement, the further plate may be adjusted with respect to the plates 8, 9 after the latter have been set. In another arrangement, shutter plates 37, 38, Figs. 8, 10, located in grooves 36 in the frame 2 on either side of the spindle 1 are adjustable vertically by screws 40. A U-shaped bracket 30 secured to the frame 2 and carrying the spindle 1 is provided with slots 34 to permit adjustment of the spindle vertically. In a modification of this arrangement two butterfly valves each. having a pair of relatively transversely adjustable plates are mounted on horizontally disposed parallel spindles. Each spindle is carried on a separate U-bracket so that the two valves may be independently adjusted vertically. The valve and shutter plates instead of being rectangular may be shaped to suit any particular sections of duct.
