Title: Improvements in or relating to automatic thread winding machines
IPC: B65H54/22
Filed: 1959-04-17
Abstract: 922,186. Winding yarns, W. REINERS. April 17, 1959 [June 6, 1958], No. 13156/59. Class 120 (2). In an automatic thread winding machine of the kind comprising a plurality of winding stations and a fault-eliminating device which is movable relative to the winding stations so as to locate each station in turn in the zone of operation of the fault-eliminating device, each winding station is provided with a control lever which is movable, on the occurrence of a fault as said station, to initiate operation of the faulteliminating device and, on completion of a wound package to a required diameter, to arrest the winding operation. As shown the invention is embodied in the type of winding machine described in Specifications 892,614 and 917,676. In normal operation rod 46 is moved up and down continuously by lever 11 attached to an oscillating shaft. Should thread F break, lever 37 pivots such that the end 37a is brought into the path of movement of lever 48. This causes control lever 31 to pivot and initiate the operation of a fault-eliminating device when it reaches the particular winding station all as described in the above Specifications. Package 21 is supported in a cradle having arms 20 to one of which is attached rod 102 fitted with a collar 103. The latter co-operates with lever 104 coupled by a pin and slot connection to a quadrant 105 which co-operates with one arm 106 of a lever the other arm 107 of which may engage under lever arm 45. As the package 21 increases in diameter it lifts rod 102 and allows lever 104 and quadrant 105 to pivot. When a predetermined diameter is reached lever arm 106 is released to allow the lever arm 107 to engage under the arm 45. This partially prevents oscillation of lever arm 45 and this causes control lever 31 to pivot sufficiently to cause rod 41 through lever 23 to disengage friction wheel 25 from the driving roller 16 and also apply a brake to arrest the traverse drum 22 thus arresting the winding operation. The movement of lever 31 in this instance is not sufficient to release the nose 35 of lever 33 to initiate the operation of the fault-eliminating device.

IPC: H02P5/50
Filed: 1966-03-25
Abstract: 1,155,551. Automatic control of speed. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 20, 1967 [March 25, 1966], No. 13415/66. Heading G3R. In material processing apparatus having at least three rotary stages (a tube stretch mill), the speed ratio of adjacent stages is kept constant by control means responsive to any error detected by a comparator of speed representative pulses which is switched between pairs of stages. Each stage is controlled by a retroactive system comprising tachogenerators G, the voltage of which is modified by course control rheostat CP N  and a fine control FP N  and applied to a motor field operational amplifier OA N  for comparison with a reference voltage D.C. and a voltage SVP, different for each stand, by which speed ratios are established. Each stage also has a pulse generator PG N  connectible to the comparison equipment FC, of which there may be only one for the mill. This is automatically connected sequentially to adjacent stages along the mill and comprises frequency multipliers SM, IM, the former coupled to SVP, to provide the desired ratio, the latter settable for scaling purposes. Comparison is made in a pulse frequency comparison circuit PFC, the output of which comprises pulses where frequency and polarity correspond to the error and drive a stepping motor MS which adjusts the fine control FP N  of one of the motor control systems. If the stretch is not to be uniform throughout the mill the signal SVP is omitted from the appropriate stands, and any pair can be excluded from the adjusting sequence. The speed of the first stand may be set by the control unit FC if the D.C. reference signal is converted to pulses and applied at A.

Inventor: BROSIUS EDGAR E
Filed: 1919-05-29
Abstract: 127,595. Brosius, E. E. Jan. 28, 1918, [Convention date]. Discharging.-Clay-guns for plugging furnace tapping-holes are mounted so as to permit of angular movement in relation to the carrier in order to allow the apparatus to be applied to furnaces the structure of which would otherwise interfere with the motion. The clay gun 6, of usual construction, is suspended from the end of a boom 7 which is carried by a vertical shaft 8 rotatably supported by a bracket 9 attached to one of the columns 5 supporting the furnace. The gun is provided with a trolly rail 10 engaged by a roller 12 on a bracket 13, which swivels in a bearing 15 attached to the end of the boom (Fig. 5). A link 18 is connected at one end to a rod 17 carried at one side of the bracket 13, and at the other to a member 19 fixed on the bracket 9. As the gun is swung from the position shown in dotted lines in Fig. 1, the link 18 causes it to rotate about the axis of the swivel bracket 13, the end of the gun thus taking a path such as is indicated by the chain line in Fig. 1. When the gun is over the trough 4, the nozzle is depressed, owing to the action of a lever 26 fulcrumed on an arm 28 carried bv the shaft 8. One end ot this lever contacts with a cam-plate 30 towards the end of the motion, and brings it to the position shown in dotted lines in Fig. 3. Tho lever thus pulls on a flexible member 24 attached to it, the other end of which, after passing over a pulley 23 carried by the rod 17, is attached to the rear part of the gun at 21, thus tilting the gun. Mechanism, part of which is shown at 31, 32, 32<a>, which may be of a similar form to that shown in Specification 127,597, is provided to hold the gun in its operative position at the tapping-hole.
