Title: An improved driving device for farm tractors
IPC: B62D11/10
Filed: 1923-06-13
Abstract: 199,395. Murnane, C. June 19, 1922. [Convention date]. Setting and retaining devices for controlling- apparatus; controlling by reins. -- A tractor is driven through friction gearing controlled by a pair of levers, 22 independently controlled by reins 25. Friction discs 6 are normally held out of gear with flywheels 5 by springs 29 which keep the levers 22 in the central position in which pawls 28 engage notches 26 in brackets 27. For forward driving the reins are pulled slightly to free the pawls 28 and then released, so that the levers are pulled outwards, the pawls passing over the notches. The arms 9 are connected to the levers 22 on opposite sides of the fulcrums 24 so that the discs 6 move normally in opposite directions and each engages with a separate flywheel being driven thereby .in the same direction. For reversing, the reins are pulled right back, each disc engaging with the other flywheel to that which it engaged for the forward drive.

Title: Improvements in or relating to the production of highly elastic corrugated tubes made of profiled metal band material
IPC: B21C37/12
Filed: 1944-08-11
Abstract: 583,205. Making flexible tubes. METALLSCHLAUCHFABRIK AKT. - GES. Aug. 11, 1944, No. 15384. Convention date, July 16, 1943. [Classes 83 (ii) and 83 (iv)] Welding.-In making elastic corrugated tubes from profiled strip metal by electric welding, - the overlapping edges after winding on a core, welding is effected by a two-part roller electrode arranged so that the current passes from one side of the wave crest into the overlapping portions, then through material filling out the wave crests and then through the other side of the wave crest to the other part of the electrode, a weld being thus produced on both sides of the wave crest. The welds may be continuous or intermittent. The strip metal 11 is wound on a core 10 of hard metal such as tool steel or chromium-plated material, and two metal wires 12, 13 are used to fill the wave crests, the outer 13. only being of metal of high conductivity. The roller electrode is made in two parts 14, 15 insulated from each other and connected to the opposite terminals of a transformer, the current passing from one part to the other through the wire 13 and 'forming welds at 21 and 22. Penetration of fluid in the tube between the two edges of the strip is thus avoided. In another form, two electrode discs 24, 25 are obliquely disposed to each other so as to form an angle of approximately 90 degrees. The joint may be cooled by a jet of water, particularly when making brass or rust-proof steel tubes. Two or more profiled bands may be wound on the core and welded together to form corrugated tubes with multilayer walls.

Patent GB-840796-A (GB)
Title: Treatment of polyethylene terephthalate filamentary textile material or textile fibres
Inventor: EGGLESTON PHILIP WILLIAM
IPC: D06M13/325
Filed: 1955-05-31
Abstract: Polyethylene terephthalate filaments or fibres are treated with steam, ammonia, or an amine, such as methylamine, until the intrinsic viscosity of the filament or fibre material is reduced to between 0.45 and 0.28 inclusive.  The fibres may be made up into fabrics before treatment.  The treatment is preferably carried out at elevated temperature and, in the case of treatment with steam or gaseous ammonia, also at superatmospheric pressure. The intrinsic viscosity of the polymer is calculated according to a formula given in the Specification.  In an example, a knitted fabric of polyethylene terephthalate having an initial intrinsic viscosityof-0.59 is treated for 18 hours at room tempe as ture and atmospheric pressure with an aqueour solution of ammonia having a specific gravity of 0.88, the intrinsic viscosity of the polymer being thereby reduced to 0.40.  In another example, polyethylene terephthalate fabrics of 0.59 I.V. are treated with steam in an autoclave at 40 p.s.i. for 6 hours and 12 hours with consequent reduction of the I.V. to 0.42 and 0.34 respectively.  In a third example, a crimped tow of polyethylene terephthalate filaments is treated with gaseous ammonia at 130 DEG  C. and 30 p.s.i. for 45 minutes, and in a fourth example a knitted fabric of polyethylene terephthalate fibres is treated for 2 hours in a 40% by weight methylamine solution at room temperature.  The treatment reduces the tendency of fabrics made from polyethylene terephthalate yarns to form small adherent balls of loose fibres when abraded. Specifications 610,183, 683,634, 697,657, 698,120, 735,171, 748,944 and 766,384 are referred to.
