Patent GB-351322-A (GB)
Title: Manufacture of new azo dyes
IPC: C09B31/047
Filed: 1930-08-29
Abstract: Disazo dyes are made by treating an aminodisazo dyestuff R1 --> R2 --> R-NH2, where R1, R2 and R = residues of the benzene or naphthalene series not containing free hydroxyl or amino groups but carrying a total of at least two salt-forming groups, with a nitroaroyl halide, reducing, condensing the resulting aminoaroyl derivative with a nitroaroyl halide, and finally reducing.  They dye cotton, wool, silk, and viscose in yellow to brown shades and may be diazotized on the fibre and developed to yield dyeings fast to washing.  In examples (1) the dyestuff 2-naphthylamine-6 : 8-disulphonic acid --> m-toluidine --> m-toluidine is p-nitrobenzoylated, reduced, again p-nitrobenzoylated and finally reduced; (m-nitrobenzoyl chloride may be used); it gives a bright orange when developed with b -naphthol and a yellow with 1 - phenyl - 3 - methyl - 5 - pyrazolone.  (2) The dyestuff metanilic acid --> 1-naphthylamine-7-sulphonic acid --> m-toluidine is treated as above and may be similarly developed.  Specification 303,026, [Class 2 (iii), Dyes &c.], is referred to.

Title: Improvements in, or relating to, boring machines for use in rock, coal or similar material
IPC: E21C25/58
Filed: 1936-09-23
Abstract: 482,133. Cutting slots in rock &c. HARDYPICK, Ltd., and HURD, F. W. Sept. 23, 1936, No. 25871. [Class 68 (i)] [Also in Group XXII] In cutting slots in a rock, coal, &c. face for receiving roof supports, a hole is drilled into the face and a cutterhead is then used having a non-rotary head which enters the hole to serve as a guide and carries two radial cutters rotating on axes perpendicular to the hole so as to elongate the latter and form it into a slot. A machine for carrying out the method comprises a fluid or electric motor 2, Fig. 2, to which is attached a casing 11 carrying a drill spindle 5 co-axial with the motor. The spindle is driven by an annular gear 9 thereon, a stationary idle pinion 8 and a gear 6 on the motor shaft 4. A hollow spindle 18, parallel to the spindle 5, is driven therefrom through an idle gear 16 and drives two further parallel spindles through its gear 13. The three spindles drive three shafts 21-23, Fig. 1, supported by bearing members 24, 25, each shaft carrying a helical fin for withdrawing the cuttings from the slot being formed. The central shaft 22 is screwconnected at 40 to a stub shaft 34 journalled in a frame 27 attached to the bearing 25. A bevel gear 37 in the shaft 34 drives opposed radial cutters 42 also journalled in the frame 27. In operation a drill is inserted in the spindle 18 and a hole, equal in length to the depth of slot required, is drilled in the coal &c., face. The drill is then removed and the shafts 21-23 inserted in the spindles 18 and a head 28 on the frame 27 is guided in the drilled hole whilst the cutters 42 cut away the sides of the hole to form the slot. Rotation of the bearing 25 under the action of the driving torque is prevented by opposed surfaces 45 thereon engaging the upper and lower faces of the slot. The spindles 18 are arranged in a plane offset from the motor casing 2 in order that they may operate close to a roof &c., face, and a drill may be inserted in the spindle 5. The cutters 42 may be rotated by worm gearing instead of bevel gearing, the two cutters then rotating in the same direction and being of opposite hand. The device may form an integral part of an electric or pneumatic drilling machine or may be driven by a flexible shaft, and is fed during operation by hand or by any known mechanical means. The drill for forming the initial hole has a helical fin 43, Fig. 4, and blades 44, 44a of different diameter arranged one behind the other at right-angles.

Abstract: 275,447. Whitehead Torpedo Co., Ltd., and Jones, A. E. Oct. 22, 1926. Torpedoes, locomotive.-A torpedo having an adjustable member controlling the closing of the air valve so that the length of run can be predetermined, is provided with means whereby the adjustment of the member to a certain position prevents the valve from closing at any period during the run of the torpedo, which therefore continues to run until the air is exhausted. As shown, the mechanism controlling the valve A comprises a lever C<3> connected by a link C to a rocker B adapted, when the lever C<3> is pressed back, to lift a pilot valve A<2> thereby causing the differential valve A to lift. The mechanism for controlling the length of run comprises a clutch disc D driven by the engine and a second clutch disc F, which constitutes the adjustable member carried by a spindle E<2> at the upper end of which is a pointer E<3>. The disc F is normally pressed downwards by a spring E' and is raised to engage the clutch disc D by the action of a slide B<2> connected to the end of the rocker B. The disc F is formed with a hole E<5> into which, when the disc reaches a certain position, a stud B' on the slide B<2> enters, the other end of the rocker B being thereby lowered and the valve A closed. To render the closing gear inoperative, the casing E<4> is formed with an overhanging projection E<7> which, when the pointer E<3> has been moved into position beneath it, prevents the clutch disc F from moving into engagement with the clutch disc D so that the disc F is not rotated by the engine and the valve remains open.
