Title: Electrical stepping motor
IPC: H02K37/04
Filed: 1972-10-10
Abstract: 1357269 Stepping motors NATIONAL CASH REGISTER CO 10 Oct 1972 [12 Oct 1971] 46572/72 Heading H2A In a stepping motor comprising first and second toothed rotors 26, 36, spaced apart on a torsionally resilient coupling member 30 and co-operating respectively with first and second toothed stators 22, 24 and 32, 34, coils 60, 61 on the stators are selectively energized and deenergized so as to alternately stress the resilient coupling member and release it from stress, stepping movement of an output member connected to the coupling member being initiated on releasing the coupling member from stress. In the motor shown in Fig. 1, the coupling member 30 is a steel shaft, all of the rotors and stators have the same number of teeth and the output member is a shaft 28 connected to shaft 30. The teeth of the two stators 22, 24 and 32, 34 are mutually staggered by half the tooth pitch. The shaft 30 may alternatively be made of titanium alloy or aluminium alloy. Alternatively, the coupling member 30 may be a coil spring. There may be a further stator 113, 115, 117, 116, Fig. 4, (not shown), energized simultaneously with the second stator and having its teeth offset from those of the second stator to ensure that the output member rotates in a predetermined direction. In a modification, Fig. 8, the stators 515, 533, have salient poles, the stator 515 carries toroidal windings and the stator 533 has salient pole windings. The output is taken from a belt 531 engaging a pinion 529 mounted on the coupling member 527 between the two rotors 521, 533. Operation.-In the motor of Fig. 1, coil 60 is energized to align the associated rotor and stator teeth. Coil 61 is then energized to move its associated rotor teeth into alignment with the stator teeth, thus torsionally stressing the shaft 30. Depending on the desired direction of rotation, either coil 60 or coil 61 is then temporarily de-energized. The associated rotor is rotated by the energy stored in the shaft 30. After half a tooth pitch of movement the coil is re-energized to pull the rotor teeth into alignment with the next adjacent stator teeth, thus restressing the shaft 30. The other coil is then temporarily de-energized and the other rotor moved through one tooth pitch to re-stress the shaft. The first coil is then again temporarily de-energized to initiate the next step. The motor of Fig. 8 operates in like manner except that, since the output is taken from between the two rotors, the output belt 531 moves in smaller steps than in the Fig. 1, motor, but at twice the step frequency. The windings of the Fig. 8 motor may be sequentially energized.

Abstract: 990,436. Bobbin stripping; drafting. TERRELL MACHINE CO. Dec. 21, 1962 [June 22, 1962], No. 48440/62. Headings DID and D1F. Fibres are recovered from strands of waste roving by drafting the strands to loosen the fibres, and by subjecting the loosened strands to an unopposed brushing disruption to obtain separated fibres. As described the bobbins B having waste roving thereon are manually passed along a feed channel 13 to rollers 15, 16 the nip of which catches the free end of the roving. Roller 16 is driven from countershaft 19 and has a friction cover to drive the smaller, smooth surfaced, steel roller 15 which is spring pressed against roller 16. An auxiliary roller 21 is provided at one end of the rollers so that if the other end of the roving is also caught in the nip the roving breaks near the bobbin surface. The roving strand ejected from rollers 15, 16 falls between guides 27, 28 on to a conveyer 26 which, due to its high speed, straightens the roving and throws it into the nip of the back rolls 32, 33 of the drafting means. Front rolls 34, 35 are adjustably spaced from the -rolls 32, 33 by an amount greater than the staple length of the roving and the draftabout 5-substantially removes all the twist from the roving. Rollers 32, 34 are driven by belts from shaft 19 and motor 20 respectively and are covered with friction material. Rolls 33, 35 are fluted and are carried on pivot mounts 43, 44 (Fig. 6 not shown). The loosened roving fibres, discharged from rollers 34, 35, are pulled apart by a nylon bristle roller 47 whose peripheral speed is higher than the moving speed. The separated fibres are then sucked by a fan 49 into a collection spoul 11. The stripped bobbins pass either to a container c or, alternatively, along a return conveyer past an operator who places an incompletely stripped bobbin on to the shoot 13.

Abstract: 1,112,261. Conveyer systems. FISHOLOW PRODUCTS Ltd. 25 Nov., 1964 [10 Dec., 1963], No. 48775/63. Heading B7L. A conveyer system of the general form described in Specification 1,047,621, and comprising a power driven endless chain 10, Fig. 3, supported on a track 11, the chain carrying vertically movable driving dogs 14 for engagement with abutments 15 on trolleys 13 movable along a track 12 and having dog lifting means 16, is characterized in that load carrying brackets 22 on the trolleys 13 are provided with rotatable and self-aligning as opposed to sliding, preselectable control means 26 for operating micro-switches m1 to m8 in a bank of switches M secured to the tracks 11, 12 and controlling the operating solenoids of known switch tongues for branch tracks of the system. Referring to Fig. 7, each of the preselectable control means comprises a U-shaped frame 28, 29 secured to the bracket 22, two vertical parallel tubes 30, 31, being secured to the frame sides 29. Mounted each for rotation between three positions on the tube 30 are generally octagonal shaped control elements 32, one for each micro-switch. As shown each element 32 comprises two plates 40 secured together and having opposed flanges 41 which co-operate with a micro-switch operating arm as described with reference to Figs. 5, 6 and 12 (not shown). The plates 40 have diametrically opposed slots to receive balls 48 which engage in conical recesses 36 in a plate 35 secured against rotation relative to the tube 30 by having a slotted portion engaging the tube 31. The balls 48 are urged into the recesses 36 by a spring 52 engaging a retaining washer 46 and acting through a pressure plate 51, thrust balls 50 and a freely rotatable thrust plate 49. The plate 35 and the washer 46 are secured between the flanges 34, 34a of a sleeve 33 on the tube 30. The control elements thus comprise separate units mounted on the tube 30, the flanges 34, 34a of adjacent units being in abutment. The conical depressions of adjacent diametrical pairs are spaced angularly from one another by 45 degrees as described with reference to Fig. 9 (not shown), and the circular bases of the adjacent recesses are close to each other as described with reference to Fig. 10 (not shown); whereby if the control element 32 is rotated not more than half the angular distance between one preselected position and another, the spring-pressed balls 48 coacting with the wide V-shapes of the depressions 36 will cause the element to return to its initial position. If the element is rotated more than half the angular distance between two positions then the balls and depressions will' ensure that' the element rotates into the next position. The invention may be applied to other operations of the conveyer system e.g. loading and unloading and stopping and starting. Moreover the load carriers may be directly mounted on the conveyer chain. Solenoid operated means for resetting the control elements 32 are described with reference to Figs. 13 and 14 (not shown).
