Abstract: 1,043,843. Bolting. C. O. OLDENKOTT. June 26, 1963 [March 1, 1963], No. 25387/63. Heading F2H. A washer comprises a plurality of circumferentially-extending, sloping, shouldered surfaces 40 on one side and a serrated surface 30 on the other side which tends to resist rotation when in contact with a surface. Two such washers 20, 22 are used to lock a nut 24. Any elongation of the bolt subsequent to tightening, is taken up by the surfaces 40, 44 on the washers causing the washers to be forced apart. The washers may be of aluminium, ferrous metal or polymerized resin. The washers may be used with a bolt having a roughened under-surface. The washers may be hexagonal to enable them to be rotated by a spanner to loosen a nut.

Title: A method of producing tetryl
IPC: C06B25/04
Filed: 1948-10-01
Abstract: Tetryl is obtained by condensing 2,4-dinitrochlorobenzene with a mixture of ammonia and primary, secondary and tertiary methylamines and then nitrating the mixture of dinitromethylaniline and dinitrodimethylaniline thus obtained. The condensation may be effected either in an aqueous medium in the abosence of any other solvent or in an alcoholic or an aqueous alcoholic medium or in the presence of an organic solvent which is not miscible with water, e.g. benzene.  The hydrochloric acid set free may be neutralized by sodium or potassium hydroxide or the mixture of ammonia and methylamine itself may be used if these are present in excess.  In examples: (1) a mixture of 2,4-dinitrochlorobenzene and water is heated and mixed with an aqueous solution containing ammonia and mono-, di- and trimethylamines.  After cooling the product is washed in the molten state with water at 80-90 DEG  C.  The mixture of dinitromethylaniline and dinitrodimethylaniline thus obtained is then dissolved in concentrated sulphuric acid and nitrated at 80-90 DEG C. by adding the solution to a nitric-sulphuric acid mixture; (2) as in (1) soda lye being present in the ammoniaamines mixture. Specification 655,708 is referred to.  The Specification as open to inspection under Sect. 91 includes an additional example in which a mixture of ammonia, methylamine, dimethylamine and soda lye is used for the condensation.  This subject-matter does not appear in the Specification as accepted.

Abstract: 714,175. Securing brushes to shafts. CAPLIN, S. R. Feb. 9, 1953 [Nov. 7, 1951], Class 80 (2) [Also in Group XXXVI] A machine for cleaning the insulating covering from electrical conducting wires comprises two wire or other suitable brushes 5, 11 mounted on shafts 4, 10 which are arranged to rotate in opposite directions, means for rotating the shafts, and means for adjusting the spacing between the brushes so that when the shafts are rotated the brushes have a wiping or brushing effect upon the electrical conductor to be cleaned when it is inserted and held between the brushes, the brushes being detachably connected to the ends of the shafts by means of bayonet-type connections. Each brush, e.g. the brush 5, Figs. 4a, 4b, is secured between a flanged portion 24 on a hollow spindle 23 and a washer 25, the spindle 23 having a spigot 22 extending into a socket 21 on the shaft 4, and a radially projecting pin 22a on the spigot fitting within a bayonet slot 21a formed in the socket 21. An extension 5a of the shaft 4 passes into the hollow spindle 23, which may be of square cross-section exteriorly or may be provided with a key &c. to prevent the brush rotating thereon. A spring &c. may be incorporated in the connection to help maintain the parts engaged, the bayonet slots 21a of the sockets 21 on the two shafts being arranged in such a direction that as the two shafts are rotated, the pins 22a are urged, against the closed ends of the slots. The shaft 10 is rotatable in a member 12 on a bolt 14 vertically movable but not rotatable in a support 2 and the threaded end of the bolt is engaged by a rotatable nut 16, whereby the bolt can be raised or lowered to adjust the separa- .tion of the two brushes. A belt 8, driven by an electric motor, not shown, engages a pulley 27 on a countershaft 28 and a pulley 7 on the end of the shaft 4, a crossed belt 32 engaging a pulley 30 on the countershaft and a pulley 31 on' the shaft 10, which is accordingly rotated reversely to the shaft 4. Alternatively, the drive to the shaft 10 can be omitted, in which case the brush 11 is rotated by frictional contact with the brush 5, or a clutch can be provided in the drive to one of the shafts to disengage the driving means at will. Again, other friction reverse gearing or separate motors can be provided for driving the two brushes, around which a guard is placed. Specification 406,298, [Group XXXVI], is referred to.

Abstract: 187,216. Svenska Aktiebolaget Gasaccumulator. Oct. 14, 1921, [Convention date]. Lamp signals.-A signal, for use as a crossing- gate signal, of the type which is operated by fluid pressure on a diaphragm and is controlled by an electrically-actuated valve, is illuminated by a lamp using the same fluid pressure as the operating mechanism. A magnet 21 is energized when a track circuit is unoccupied, so that gas from a pipe 28 passes through pipes 9, 25, a chamber 18, and pipe 17, to the underside of a diaphragm 15, thereby raising the arms 14, 7 and the spectacle disc 4 to the aperture 3. The occupation of the track-circuit de-energizes the magnet 21 so that the supply of gas from the pipe 25 is discontinued and the underside of the diaphragm 15 is opened to atmosphere through a pipe 24, thereby bringing the disc 5 opposite the aperture 3.
