Abstract: 359,521. Heat-treating crank shafts. POLLAK, J. E., 20, Holborn, London.- (Deutsche Edelstahlwerke Akt.-Ges. ; Remscheid, Germany.) July 16, 1930, No. 21596. [Classes 72 and 82 (i).] In a method of heat-treating crank shafts, the wearing surfaces of the shafts are heated by a slot nozzled burner giving a very hot flame, the shaft being rotated so that when the surfaces have been raised uniformly to the desired temperature they are cooled immediately. When treating a crank pin A on the shaft, the latter is mounted in a lathe and the pin is heated by a burner B having a slot d approximately the length of the burner to be treated. The burner is mounted at f on a slidable carriage and provided with connections a, b, c for water, oxygen and acetylene respectively. The water is conveyed by a pipe e<1> to the bores e in the burner head and leaves bv a tube e<11>. The heated pin is cooled by nozzles C, C<1>. The pin may also be cooled by jets of air, artificially cooled if necessary or by immersion in a bath of liquid. The journals may be hardened in the same manner. The shaft is made of steel containing 0À35 per cent of carbon, 0À8 of chromium and 0À2 of molybdenum and is normalized before treatment by quenching in water from 830‹ C. and annealing at 630‹ C.

Title: Improvements in change speed gears
IPC: F16H29/04
Filed: 1936-08-06
Abstract: 464,074. Variable - speed gearing; swash-plate mechanism. LAUB, A. Aug. 6, 1936, No. 21696. Convention date, Aug. 7, 1935. [Classes 80 (ii) and 80 (iii)] An epicyclic gear is controlled by a swashplate and ratchet device and a reverse drive is provided. The driving shaft 1 extends through the whole gearing and is journalled in the driven shaft 2. A swash-plate 3 has its tilt variable by worm and screw gearing 10, 8, actuating a body 9, notches in a rotatable part of which engage arms 11 on the swash-plate. A ring 4 sliding on the plate is connected by rods 6 to two wheels 7 provided with roller ratchets. The wheels 7 when acting impart a continuous rotation to a worm-shaft 12 through being connected with it on one hand directly through a pinion 12<a>, and on the other through an intermediate pinion 12b, and another pinion 12<a>. A worm 12<c> on shaft 12 meshes with a worm-wheel 13 loose on shaft 1 and to this worm-wheel is rigidly secured a wheel 14 provided with dog-clutch teeth. A wheel 15 is keyed to shaft 1 and meshes with planets 17 on a spider 2<a> integral with shaft 2, the planets also gearing with internal teeth 16b on a member 16 loose on shaft 1 and slidable thereon, the boss of this member having dog-clutch teeth 16<a>. The member 16 is also toothed at 16<c> and an intermediate wheel 19, Fig. 4, may be interposed for reverse drive. If the swash-ring be square with shaft 1, and the member 16 be moved to the left to engage wheel 14, the wheel 15 rotates shaft 2 through the planets 17, the member 16 being held fixed by the worm 12<c>. If now the swash-plate be tilted, the member 16 is moved forward and the speed of shaft 2 is increased. When it reaches that of shaft 1, the member 16 is slid to the right to engage dogs on wheel 15 and a direct drive is obtained. To simplify speed changing, the lever 18<a> for actuating the member 16 is preferably interconnected with the gear for adjusting the swash-plate. For reverse drive, the member 16 is placed in mid-position, Fig. 4, the swashplate so tilted as to give an increased speed to this member, and the wheel 19 is brought into mesh with wheel 14 and teeth 16<c> whereby the planet-wheels 17, and therefore the shaft 2, rotate in the opposite direction.

Abstract: 1,194,704. Polyester films and filaments. KANEGAFUCHI BOSEKI K.K. 11 May, 1967 [11 May, 1966], No. 21870/67. Heading B5B. [Also in Division C3] The stickiness of copolyester films and fibres is reduced by incorporating into the copolyester a polyolefin, a polybutadiene or a paraffin wax in an amount of 0À01 to 25% by weight of the copolyester. The copolyester compositions may be extruded by themselves into films or fibres but preferably are used in the manufacture of composite filaments by separately melting the copolyester composition and a homopolyester or different copolyester, and extruding the two melts through the same orifice to form a single filament in which the two polyesters extend in side-by-side conjugated relationship along the entire length of the filament. In Example I, the following copolyester compositions were melt spun and the resulting filaments lubricated with an aqueous oil emulsion, (i) copoly-(ethylene terephthalate adipate) with polyethylene; (ii) a copolyester of ethylene glycol, polyethylene glycol and terephthalic acid with polyethylene, (iii) a copolyester of ethylene glycol, terephthalic acid and adipic acid with polypropylene, (iv) a block copolyester of poly- (ethylene diphenoxyethane-4:4<SP>1</SP>-dicarboxylate) and poly-(1:10-decylene diphenoxyethane-4:4<SP>1</SP>- dicarboxylate) with polyethylene, (v) a copolyester of p-(beta-hydroxyethoxy) benzoic acid, 1:10-decanedicarboxylic acid and triethylene glycol with paraffin wax. In Example 2, composite filaments were made by extruding together polyethylene terephthalate and a mixture of a copolyester of ethylene glycol, polyethylene glycol and terephthalic acid with polyethylene, the resulting filaments being lubricated with an aqueous oil emulsion, wound and possibly drawn 5 x at 80‹ C. In Example 3, a composition of a copolyester of ethylene glycol, polyethylene glycol and terephthalic acid with polyethylene was melt extruded at 260‹ C. through a T-die into a film. In Example 4, composite filaments were made in a manner similar to that in Example 2 by extruding together (a) a copolyester of ethylene glycol, terephthalic acid and isophthalic acid and a composition of a copolyester of ethylene glycol, terephthalic acid and adipic acid with polyethylene, (b) a polyester of p-(beta-hydroxyethoxy)-benzoic acid and a composition of a copolyester of ethylene glycol, polycaprolactone diol and terephthalic acid with paraffin wax.
