Doffing arrangements; lifting rails. - In spinning, doubling, and similar machines in which the bobbin or lifting rails are carried upon a rotatable device for the purpose of doffing, the bobbin rails c, mounted on opposite sides of the rotatable member or capstan m, are hinged at d, so that, upon rotation of the capstan to bring a fresh set of empty bobbins a into spinning position, the rail carrying the full bobbins is engaged by a bracket e and maintained in the position shown in Fig. 3 until the required quantity of yarn is wound on to commence the fresh set, the yarn is severed and' the full bobbins are replaced by empty bobbins, whereupon the bracket e is lowered to allow the rail to fall and to be engaged by arms k which are operated to seat it again on the capstan, as shown in Fig. 5, in which position it is locked by sliding devices arranged inside the capstan, the empty bobbins being maintained in position during the movements by a rod g carried by arms f.
Patent GB-1470082-A (GB)
Title: Electromagnetic machine rotor assembly
IPC: H02K9/22
Filed: 1974-01-31
Abstract: 1470082 Cooling dynamo-electric machines SBW ENGS Ltd 24 Jan 1975 [31 Jan 1974] 04435/74 Heading H2A  The rotor of an electric motor is cooled by having a heat pipe extending axially therein, with its evaporating portion within the rotor and its condensing portion outside the rotor. The rotor of a two-pole D.C. commutator motor has a shaft 14 mounted in bearings in the housing. The active part of the rotor is enclosed by a heat shield and the shaft 14 has an axial bore 15 extending through the active region to a tapered portion 17 outside the housing which portion carries a hub with cooling fins (21, Fig. 1, not shown) secured by a nut (23) on a stub shaft (24). The bore is filled with water through a duct 24 which after exhaustion of all air is sealed. The heat generated in the rotor vapourizes the water which moves to the tapered portion and there condenses due to the cooling action of the fins (21), which action is improved by allowing passage of air through apertures (22) therein and/or by making the inner surface of the tapered portion 17, fluted, ridged or by embedding copper spheres therein (Figs. 3-5, not shown). The water condenses on the inner surface and is forced back to the evaporating portion by the centrifugal force acting along the tapered wall. The bore has a fusible plug 7 for preventing failure due to overpressure during extreme heating. The tapered portion 17 will eventually accumulate pockets of incondensible gas, which must be removed. The stub shaft 29 is thus made hollow (Fig. 3, not shown) and is closed either by an annular end cap which leaves an annular chamber connected to the condensing portion in which the gases collect, or the end cap has an external annular recess coaxial with an axial bore in which the gases collect. The presence of the gases is detected by temperature measurements in the recesses of the caps, since there is a large temperature dinerence across the vapour/ gas boundary. To help cool the windings, copper discs are spaced axially along the windings to conduct heat to the shaft or to subsidiary pipes containing water which extends through the windings and communicate with the evaporating portion (Fig. 6, not shown).

Abstract: 564,142. Cams. HUMBER, Ltd., SAMPIETRO, A. C., and-OLIVER, W. T. March 27, 1943, No. 4996. [Class 80 (iii)] Consists in a method of setting out a cam which will operate relatively quickly and have a minimum tendency to set up resonant vibrations in associated springs &c. Assuming that about onehalf of the cam is to be substantially semicircular in shape as at a, this semicircle is extended by the broken line into a circle, and a number of radial lines e equally spaced are drawn from the centre. Along the lines e and extending from the peripheral broken line, distances are marked off corresponding to the ordinates of the equation y=sech x, where y is the movement of rod b and x is the angle turned through by the cam, the maximum ordinate being set off along the central line e. With each of the points so obtained as centre, a circle f is struck with a radius equal to that of the roller d. The shape of the cam is then obtained by drawing a line tangential to these circles. In a modification, the distances are set off inwardly from the circumference of the basic circle.
