Title: Improvements in method and apparatus for tensioning thread, yarn or the like
IPC: D02J1/22
Filed: 1949-04-20
Abstract: 672,912. Stretching textile yarns &c. DAN RIVER MILLS, Inc., and JENNINGS, H. Y. April 20, 1949, No. 10424/49. Classes 120(ii) and 120(iii) [Also in Group XIII] To enable a saturated yarn, thread, cord or the like to be dried at a very high load of tension, somewhere near to its breaking load, without undue stretching or breaking as a result of stretching of the yarn during this operation, the yarn is previously stretched by tensioning it at a load less than that at which it is dried. A bobbin 14 carrying the saturated yarn is mounted on a rotatable plate 16 which is retarded by a friction rubber 34 bearing beneath the plate and secured to one arm 20 of a sleeve 24 located on a spindle 22. A spring 38 urges the sleeve upwardly and the rubber 34 into contact with the plate. A second arm 26 carrying a roller 28 contacting the yarn on the bobbin is attached to the sleeve and is maintained in contact with the bobbin by a spring 30 attached to the arm 20 drawing the arms towards the bobbin, the arrangement being that as the effective diameter of the wound bobbin decreases the rubber 34 moves inwardly of the plate 16 to maintain. the resistance of the yarn to unwinding substantially constant. The yarn passes from the bobbin 14 around a pair of multiplegrooved sheaves 44 to a pulley 60 mounted on a weighted lever 62 engaging a Sylphon bellows 74 connected by a conduit to a second bellows which effects the speed of one. of the sheaves 44. As the yarn passes from the sheaves 44 to the pulley 60 under load, which load is substantially less than the breaking load of the yarn, the yarn is permitted to stretch, the increase in length being compensated by the retardation of one of the sheaves 44. From the pulley 60 the yarn passes around a second pair of grooved sheaves 78 associated with intra red drying lamps 80 and is maintained at a very high constant tension. After being dried the yarn is collected on a bobbin 82. Saturation of the thread may take place between the bobbin 14 and the sheaves 44. Specification 548,794, [Group III], is referred to.

Title: Peroxygen-containing borate products and their stabilization
IPC: C01B15/12
Filed: 1950-04-28
Abstract: Peroxygenated sodium borate compositions are prepared by adding boric acid or anhydride, or a sodium borate containing an excess of boric acid to a sodium borate, adding hydrogen peroxide (or if the sodium borate contains pentaborate, adding sodium peroxide and/or hydrogen peroxide) and evaporating to dryness if desired under reduced pressure at 50-90 DEG C, the amount of peroxide added being sufficient to result in a mol-atomic ratio of active oxygen (calculated as H2O2) to sodium greater than 0.5, and if desired greater than 1, and the amount of boric acid &c. used being sufficient to give a product in which the Na2O : B2O3 ratio is substantially less than 0.5, e.g. 0.35.  In a modification, the boric acid &c. is added in two portions, the first giving a Na2O : B2O3 ratio of less than 0.7, and the second addition reducing the final Na2O : B2O3 ratio as above being made after evaporation to dryness. In a further modification, boric acid is added to a dry peroxygenated sodium borate in which the Na2O : B2O3 molar ratio is less than 0.7, and the mol-atomic ratio of active oxygen (calulated as H2O2) to sodium exceeds 0.5.  The compositions are useful in neutralizing alkalinity in textiles due to soap.  They may be stabilized by the addition of anionic or non-ionic detergents, e.g. long chain sulphated alcohols, long chain alkyl arylsulphontes, long chain fatty acid amides or polyglycol ethers, which may be added at any stage in the manufacture of the perforate composition.

Filed: 1921-04-09
Abstract: 182,898. Morgan, S. B. April 9, 1921. Dynamos and motors, cooling; field magnets, cooling; pole-pieces and cores.-In a dynamoelectric machine having cast pole-pieces upon which field coils are wound and in which radial passages are formed, a fan is mounted upon the armature spindle and draws air into the casing and forces it through the passages in the polepieces to cool them. In the construction shown in Fig. 1 the fan j mounted in the end plate cover o draws in air through the radial apertures m. Part of the air passes out through the peripheral apertures n and part through the apertures r, q in the other end plate p after passing through the machine, while the remainder passes out through the radial apertures in the pole-pieces. In a modification the air which passes out through the apertures n is led by passages w, Fig. 5 to the outer ends of the apertures d in the upper pair of pole-pieces, so that air is forced into the casing through the upper pair of pole-pieces. In place of the apertures m, suitable pipe inlets may be provided for supplying fresh air to the casing. In this case the peripheral apertures may be dispensed with so that the sole outlets for the air are the apertures in the pole-pieces. The poleshoes c are formed as detachable sleeve members retained in position by fixing-studs. The polepieces may be cast so that the cross-section of each is a rhomboidal parallelogram as indicated at b<1>.

Title: Fault indicator circuit for motor vehicle battery charging systems
IPC: H02J7/14
Filed: 1971-04-22
Abstract: 1323267 Protective arrangements GENERAL MOTORS CORP 22 April 1971 [29 April 1970] 10669/71 Heading H2K [Also in Division H3] A circuit to indicate faults in a vehicle battery charging system which includes an alternator 26 having a plurality of windings 30a ... 30c and a full wave rectifier 32 connected therewith, comprises an indicator, e.g. a lamp 16, connected to a transistor Q3, the transistor being controlled by a differential amplifier which provides an output when a voltage at a junction in the system and a "reference" voltage differ. The amplifier comprises transistors Q1, Q2, the base of the transistor Q1 being connected by a resistor 46 to the junction between a winding 30a and the rectifier. The base of the transistor Q2 is connected to a point between voltage dividing resistors 48, 50 connected across the alternator rectifier bridge output. Normally the voltages applied to the bases are equal, the amplifier is balanced and Zener diodes 52, 54 are non-conductive. In the event of overvoltage of the system, the amplifier remains in balance, but the Zener diodes 52, 54 break down and bias the transistor Q3 into conduction to light the lamp 16. In the event of an excessive A.O. component at the junction, e.g. due to an open-circuited stator winding, the voltages on the collectors of the transistors Q, Q2 would be caused to alternate and alternately break down the Zener diodes 52, 54, the transistor Q3 again being biased on. An increase in the D.C. voltage at the junction, e.g. due to an open or shortcircuited rectifier diode, unbalances the amplifier, the voltage at the collector of Q2 increasing to break down the Zener diode 54. Should the system voltage exceed that of the battery by more than a predetermined amount, e.g. due to a loose cable, the input signal to Q1 would exceed that to Q2 so that the voltage at the collector Q2 would increase to break down the Zener diode 54. In an alternative arrangement the neutral point of the stator windings 30a ... 30c may serve as the junction. An amplifying transistor may be connected between the differential amplifier and the transistor Q3, Fig. 2 (not shown).

Title: Improvements in or relating to poultry batteries, or the like
IPC: A01K39/00
Filed: 1959-03-31
Abstract: 902,879. Poultry batteries; animal-feeding appliances. SHEPHERD & SONS Ltd., JOHN, and SHEPHERD, R. June 24, 1960 [March 31, 1959], No. 10746/59. Class 5(2). Food is supplied to the troughs 17 of a poultry battery from hoppers 16 mounted on a trolley 15 which is caused to move along rails 19 mounted on the frame 10 of the battery. The trolley is driven by a power-driven cable 13 which also reciprocates scrapers 11 over droppings trays 12 provided beneath each tier of cages, but is disengageable from the said cable to enable the scrapers to continue operating whilst the trolley remains stationary. Engagement of the trolley with the cable 13 is effected by means of a clamping lever 20 mounted by bolts 21, 23 on a plate 15a fixed to the trolley. Also mounted on the bolt 23 are two cam members 25, 26 the former being fixed to the plate 15a, and the latter being rotatable on the bolt 23 by means of an operating lever 27. Thus as the lever 27 is rotated, the two cam members 25, 26 co-operate to move the clamping lever relative to the cable 13. The lever 27 may be set to the cable-engaged position manually, by pulling on a cable 28 but means may be provided to move it to the cable-disengaged position automatically after the trolley has made one reciprocation along the battery. These means may comprise an abutment 32 resiliently mounted on the battery frame 10 and urged towards its uppermost position by springs 34, the abutment being depressed to allow the level 27 to assume the cable-engaged position (shown in full lines in Fig. 5) at the beginning of its operation. Directly the trolley commences to move, the lever 27 slides over the top of the abutment 32, which then resumes its uppermost position ready to engage the lever 27 at the end of one reciprocation of the trolley, thus pushing the lever to the cable-disengaged position (shown in broken lines in Fig. 5). A parking switch may be provided to switch off the motor driving the cable 13 after the trolley has been released from the cable, and this being so, a push-button switch may also be provided in the motor circuit for by-passing the parking switch to enable the scrapers to continue operating after the trolley has stopped. A time switch may be put in the circuit to control the system automatically, and a single time switch may be arranged to control the operation of a number of batteries. Specification 714,268 is referred to.

Filed: 1917-07-27
Abstract: 117,685. British Thomson - Houston Co., (General Electric Co.). July 27, 1917. Transformers.-In a transformer core with a number of angularly spaced units with windows to receive the windings, the inner legs of the units are joined to form a leg of the core and consist of laminations of uniform width on both sides of a plate passing through the axis of the core leg, and narrower laminations on one or both sides of the first set. Each unit has an inner leg 10 and outer leg 11 with yokes 12, and may be built up of L- shaped laminations. In the form shown in Fig. 2, each unit consists of a layer 33 of laminations, a layer 32 of laminations of the same width but displaced as shown, and layers 26, 28 of narrower laminations. The units are put together to leave a triangular axial passage 38 which may be used for ventilation or occupied by the clamping-bolt. The window surfaces of the layer 28 form a continuation of the side of the layer 26 of the next unit, and the arrangement gives a nine-sided figure as the cross-section of the central leg. The layers 26 may be omitted and the number of laminations in the layers 28 increased. The laminations in the layers 33 may be adjusted to fill the space 38, thereby leaving a space in each unit between the core and the winding for ventilation; or the laminations may be adjusted to leave an hexagonal passage in the centre and to form a core leg with an hexagonal cross-section. A modification suitable for large transformers is shown in Fig. 6. Each unit contains a layer 61 of wide laminations which extend nearer to the centre of the core leg than the others. Each extension is rectangular and engages an extension of another unit. Four widths of laminations are employed in the form shown in Fig. 7, and ventilating-spaces 78 are formed.

Abstract: 150,359. British Thomson-Houston Co., (General Electric Co.). Aug. 1, 1916. Thermionic relays.-A discharge device comprising an electron-emitting cathode, an anode, and a third electrode, maintained at such relative potentials that the device has a " negative resistance " as described in Specification 15555/15, is now provided with a discharge-controlling electrode. A variable potential is imposed on the discharge-controlling electrode, producing corresponding variations in the numbers of primary electrons reaching the third electrode and of secondary electrons emitted by it, and therefore large variations in the current through the third electrode. In one construction of tube, a W- shaped cathode filament '2, Fig. 1, is situated within a frame, over which is wound a wire 11 constituting the discharge-controlling electrode. On opposite sides of these electrodes are the two parts of the anode, consisting of metal frames 6 wound with wire, or of perforated plates. Beyond these are plates 7 acting as third electrodes; they may be electrically connected. Exhaustion of the tube is carried to such a degree that there is no evidence of gas ionization during working. In another construction, the discharge-controlling electrode is a rod co-axially within a helical filament cathode, which is surrounded by an anode of coiled thick wire and by a cylindrical third electrode. The anode is attached to a disk transverse to the axis of the electrodes. In this case it is preferable to make the discharge-controller electro-negative with respect to the cathode, the consumption of current in the circuit of these electrodes being then very small. Fig. 2 shows application of the invention to the amplification of electric oscillations. The receiving antenna 18 is inductively coupled to the cathode 2 and discharge-controlling electrode 11. Batteries 14, 15 impose the required potentials on the anode 4 and third electrode 7. Amplified potential variations are generated at the terminals of a resistance 16 in serics with the third electrode and cathode. These variations may operate a detector or be further amplified. The tube may also be used for transmission, by connecting inductance and capacity 20, 21, Fig. 3, in the circuit of the third electrode 7 and cathode, when electric oscillations occur, the amplitude of which is determined by the discharge-controller 11, connected inductively to a telephone or like circuit 22.
