Abstract: 1291104 Break spinners TMM (RESEARCH) Ltd 6 July 1970 [8 July 1969 (2)] 34329/69 and 34330/69 Headings DID and DIN  In a break spinner, Fig. 3, fibres are fed from a sliver entering feed trumpet 24 by a feed roller 25 to an opening roller 27 from which they are directed via straight passage, lying in the same plane as the opening roller, formed of ducts 29 and 14 to the fibre collecting surface 19 of a spinning rotor 11 which may be provided with spikes (not shown). Yarn twisted from the fibres is withdrawn through delivery duct 18 by delivery rolls 21 and 22. Opening roller 27 and spinning rotor 11 are each carried on a motor output shaft. The opposite ends of which carry brake drums. Access is gained to the roller 27 and rotor 11 by means of covers 41 and 15 respectively removal of which actuates cams 43 and 36 to apply brake arms 44 and 45 and 37 and 38 respectively to the brake drums. In an alternative embodiment, Fig. 7, the fibre feeding system and spinning system are housed in separate housings 105 and 122 respectively which are mounted for vertical sliding motion on pillars 104 and (103) held in their uppermost operative position by a pneumatic cylinder 139. In operation a feed roller 106 is driven by a chain 110 via an electro-magnetic clutch 112, an opening roller 116 by a belt 120 and the spinning rotor 123 by a belt 126. Lowering the housings disengages the respective drives and applies pairs of V formation brake shoes 150 and 151 to the roller and rotor pulleys respectively. In the lowered position also the lower housing disengages the upper housing which comes to rest on stops 149 and allows a front cover 128 to be opened for access to the spinning rotor. An "L" shaped lever (113), Fig. 6 (not shown) operates in combination with the delivery roller 106 against which it is biased by a spring (115).

Title: Single-phase synchronous motor
IPC: H02K7/118
Filed: 1971-07-22
Abstract: 1353082 Electric motors CROUZET SA 22 July 1971 [31 July 1970] 34403/71 Heading H2A A single phase synchronous motor comprises a rotor mounted between two end brackets 1, 2, Fig. 1, and one of the brackets 1, has a groove or aperture 11 engaged by a pin 10 mounted on one end of an arm 9 which, at its other end, engages an eccentric 6a on the rotor shaft 5, the groove or aperture 11 having a stop 11a, Fig. 2, engaged by the pin when the rotor rotates in the direction opposite to that desired. The eccentric 6a is an integral part of a plastics moulding 6 supporting a permanently magnetized ferrite ring 4. A spring 7 prevents axial movement of the rotor and through a washer 8 ensures friction between the eccentric and the arm 9. For clockwise rotation the pin slides freely along edge 11b of the groove or aperture. If the rotor initially rotates anticlockwise, the pin strikes stop 11a and then begins to rotate clockwise. Figs. 4-7 (not shown) illustrate rectangular grooves or apertures 11 associated with a member which can occupy either of two positions in the groove or aperture to permit selection of the desired direction of rotation of the motor. The member may be controlled manually or through a cam, or by an electromagnet or an electric heating element.

Traversing-cutter and guillotine machines.- An apparatus in which cutting blades have a movement in overlapping arcs through the plane in which the material is held is described applied to a machine for cutting fabrics on a bias of the type disclosed in Specification 163,674. Reversible cutting blades 24a, Fig. 7, are mounted slantways in a carrier 22a connected by a, parallelogram linkage 17<a> to a plate 16a fixed in the frame 10, 11, 12 of the machine, and reciprocated through a lever 31<a> mounted on a pivot 32<a> and a rod 34<a> from a cam 36a shaped to give a quick return motion. In a modification, Fig. 2, the parallelogram linkage is differently arranged and an edge cam is substituted for the cam 36a. The cam 36<a> is bolted to a disc 47 keyed to a sleeve 52, carrying a pinion 53 meshing with a rack 68 from a slider-crank mechanism 60, 63, 65 actuated from a shaft 67. The material is clamped during cutting by a bar 68 operated through a rod 70 connected by a lever 71 to a rock-shaft 72 carrying a quadrant 73 meshing with a rack 74. The rack is operatively connected to one link of a toggle mechanism 78 actuated from a cam 82 on the shaft 67. In operation the material is fed by rolls down between the clamping bar and the cutters; the cam 82 then actuates the toggle, and, while the material is held, the blades 24a sweep in overlapping arcs through the plane of the material to sever the latter in a continuous cut.

Title: Production of potassium permanganate
IPC: C01G45/12
Filed: 1957-11-08
Abstract: <PICT:0860548/III/1> In preparing potassium permanganate from potassium manganate by electrolytic oxidation, a solution of potassium manganate in aqueous potassium hydroxide is diluted with the product solution referred to below, of lower concentration, the mixture is electrolytically oxidized, potassium permanganate is crystallized from the oxidized solution leaving the aforesaid product solution, from part of which potassium hydroxide produced in the oxidation is recovered.  The concentration of the solution to be electrolysed is such that after oxidation the concentration of permanganate does not exceed the saturation concentration.  In the preferred embodiment, shown in the Figure, a concentrated potassium manganate solution is prepared in vessel 1 by dissolving potassium manganate in a portion of the mother liquor from the crystallization and wash water employed in washing the permanganate product.  The solution is then filtered and pumped to vessel 4 where it is diluted with a second portion of the mother liquor from the crystallization and heated with live steam before being pumped to electrolytic cell 7.  After oxidation therein the solution containing permanganate is passed to a gas separator 8 and thence to an apparatus which comprises a vaporizing section 11 into which the solution is pumped together with mother liquor from a crystallizing section 5.  In the vaporizer the pressure is reduced and evaporation takes place causing a reduction in temperature and consequent supersaturation of the solution and the liquid then passes downwardly into the crystallizing section where permanganate crystals form on nuclei already present. The crystals are drawn off as a slurry and separated in a centrifuge, mother liquor being returned to the crystallizer.  The crystals are then washed and dried.  The mother liquor is withdrawn from the upper part of the crystallizer and partly recycled to vessels 1 and 4 as previously described and partly evaporated to recover potassium hydroxide formed in the process which can be reused to make more manganate.  Potassium manganate and permanganate separate from the liquor during evaporation and may be returned to vessel 1. Full details are given of suitable concentrations of the solutions and of temperatures.  Specification 860,549 is referred to in connection with the electrolytic oxidation proper.

At the first feed the dial needles knock-over, but the cylinder needles, having previously been raised to clearing level, are lowered to what is virtually the tucking position and their loops are not knocked-over. At the second feeder, the cylinder needles knock-over while the dial needles tuck, and so on.
