The frame consists of a pair of end plates 1 on a girder 2 supported by legs 3 provided with wheels 4, the girder acting as a support for the workpiece (shown chain dotted) which may be a flat or corrugated sheet of steel, brass, aluminium, asbestos, timber or fabricated material. The guide rails 5, 6 and chain 7 extend between the end plates 1, the rail 5 5 being engaged by thrust pads 10 on an inverted V-shaped bracket 9 of the carriage which also has a pair of rollers (18, 19, Fig. 4) engaging the rail 6, roller (18) being mounted on a lever acted on by a spring (20) which serves to press roller (18) against rail 6 and bracket 9 against rail 5, the spring tension being adjustable by means of a screw (21). The motor 12 drives through a variable speed belt drive the sprocket 14 which engages the chain 7 to effect movement of the carriage along the rails, the chain having open links 15 at its ends to terminate the traversing movement. The motor unit is rockable about a pivot (16) to disengage the sprocket from the chain to permit the carriage to be traversed manually. The carriage also carries a cutter head 22 consisting of a motor 23 connected by a belt drive 24 to a shaft 25 carrying the cutter, and the cutter head is vertically adjustable on a pillar (45, Fig. 2) by an adjusting nut (47), a clamp being provided to secure the head in its adjusted position. The workpiece is clamped to the supporting beam 2 by spring steel fingers (29, Fig. 4) secured to shafts (30) having levers (31, Fig. 3) engaged by screws (33) whereby the shafts are rotatable to urge the fingers against the workpiece. The workplace may also be supported by tables (37, 41, Fig. 4) extending forwardly and rearwardly of the supporting beam 2, the tables being clamped to rod-like supports (38, 42) and carrying a guide rail and adjustable stops.

Abstract: 574,167. Salt bath furnaces. GRIFFIN, J. D. March 2, 1943, No. 3442. Convention date, Nov. 21, 1942. [Class 39 (iii)] [Also in Group XII] An electrically heated salt bath furnace suitable for heating, for example, the cutting ends of rock drills, comprises a container 25 having a cover 27 with a slot 29 through which the drills 26 are inserted to rest on an electrode D at the required level below the bath surface. A resistance heater A is arranged below the electrode D to melt the salt, after which it functions as an electrode in combination with the electrode D. Circulation of the molten material from one side to the other of electrode D is provided for by channels 39, 40. Racks 42, 42a are provided to hold the upper ends of the drills. Fumes from the bath are discharged through holes 48 to a flue 52. The Specification as open to inspection under Sect. 91 describes the use of a pair of resistance heaters A, B, Fig. 1a (cancelled), which serve also as electrodes when the salt is fused and becomes conducting. In another arrangement, the elements A, B are connected diagonally so that the potential difference is equal at all points along their length. The elements may be in series, or parallel, or a series-parallel arrangement may be used. In a three-phase circuit two phases are connected to the ends of a resistance and the third phase to a plate electrode. In another arrangement a switch may be provided to cut out the resistance heating when the electrode heating becomes operative, and the metallic container may act as one electrode. The resistance heater A is of bent metal strip, the electrode area of which may be increased by plates 34 connected at one end only, while the end 31a may be of smaller cross-section than the end 31b. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in machines for subjecting synthetic yarns to heat and bulking treatments
IPC: D02G1/02
Filed: 1961-01-30
Abstract: 976,400. Finishing yarns; twist tubes. G. BATSCH. Jan. 30,1961 [Feb. 4, 1960], No. 3505/61. Headings DID and D1F. [Also in Division H5] A machine for subjecting a yarn (or a plurality of yarns) of synthetic material e.g. multifilament nylon, to two successive heat treatments and at least one intermediate bulking treatment e.g.false-twist'"creping" or edge crimping, comprises two separate channels which are adapted to be heated and are arranged adjacently parallel in a common casing, a bulking device and yarn guides disposed outside the casing and arranged to guide the yarn, after its passage through one of the channels, through the bulking device, around the casing and into the other channel, whereby the yarn travels through the two channels in the same direction. Each separate channel may be formed or provided in a metal block containing electrical heating resistances and both blocks may be enclosed in the casing and heat-insulated from one another by material or air filling the casing. As shown in Fig. 1, yarn 1, 2, in being subjected between delivery cops 3a, 3b and receiving cops 4a, 4b to the heating and bulking treatments, passes through guides 50, 50a, tension devices 12, 12a, delivery devices 13, 13a, channel 10, guide 14 and false twist spindles 15, 15a, over pulleys 16, 16a, through delivery devices 51, 51a, over pulleys 17, 17a, through channel 11, guide 18, false-twist spindles 19, 19a and over pulleys 20, 20a, and delivery devices 52, 52a. The two spindles of each pair rotate in opposite directions so that a "no-torque" crepe yarn is produced. The temperatures of the blocks (indicated by thermometers 24, 25) and the speeds of the spindles and/or the circumferential speeds of the delivery devices may be varied and/or different. False-twisting may be limited to one stage with braking devices replacing devices 52, 52a, Fig. 3 (not shown) or edge-crimping (in one or two stages) substituted therefor, Fig. 4 (not shown). A casing 5 houses aluminium blocks 6 and 7 or a single block, Figs. 5 and 6 (not shown) heated by electrothermally and/or electronically controlled and stabilized resistances 8 and 9 and providing the tubular channels 10 and 11. In the false-twisting apparatus shown in Figs. 7 and 9, each pair of spindles 15, 19, (or 15a and 19a) is mounted in a common support 26a, 26b, itself pivotally mounted in a member 27 rigid with the machine frame so that the spindles can be shifted manually between positive, spring controlled positions into or out of contact with a driving belt 29.
