Class 120(2) A textile winding machine, particularly a cross winder with split traverse drums is characterized in that each split drum is formed from two internally unconnected drum parts which are separated from one another by a continuous separating gap, each of the drum parts being individually mounted on a separate supporting shaft and driven on its outer side. The drum parts may be so reduced in the axial direction that they virtually become disc flyers. The two parts may be driven through a common gear drive in such manner that two driving gearwheels situated on a common shaft co-operate with driven gear-wheels on the drum driving shafts. There may be separate drives for the two sides of the machine or the drives to the two sides may be taken from a common central drive shaft. Instead of gear-wheels, toothed band drives may be used. In the arrangement shown, the two halves 48, 49 of a split drum are formed as truncated cones each half being individually mounted and driven. The driving shafts 50 in this embodiment are inclined in relation to one another such that the generatrix 55 of the drum parts, touched by the bobbin 15, is a straight line. With this arrangement also the thread guide slit 57 between the two halves widens out in the downward direction. The two adjacent halves of adjacent split drums or disc flyers may be mounted on a common shaft and both driven thereby.

Title: Digital data storage apparatus and methods employing the spin echo technique
IPC: G11C11/16
Filed: 1955-07-11
Abstract: 798,021. Electric digital-data-storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 11, 1955 [July 14, 1954], No. 19972/55. Class 106 (1). In a " spin-echo " digital data. storage device employing stimulated " echoes (Z-axis storage) or " mirror " echoes (XY - plane storage) spurious echoes, due mainly to the effect of each data pulse on preceding pulses, are reduced by suitably varying the inhomogeneity of the external polarizing field. It is stated that a variation of the inhomogeneity of the polarizing field destroys XY- plane storage while leaving Z- storage unaffected, and that XY storage that is so destroyed can be " resuscitated " by a second variation in the polarizing field. Four arrangements of pulses are described. illustrating these effects. The first, Fig. 18A, shows how if coils 33, 34, Fig. 1, are energized in accordance with the function #(t), either in the region C or C<SP>1</SP> then no mirror echoes are produced. The second shows how a pulse after a 90-degree recollection pulse results in no echoes (this is because after the recollection pulse the precessing nuclei are in the XY-plane) whereas a pulse (shown dotted) before the recollection pulse has no effect on the echoes. Figs. 19A and 19B (which shows two alternative forms of f(t)) show respectively how mirror and stimulated echoes can be destroyed and then resuscitated. In a further arrangement (Fig. 19C, not shown), by using a 45 degree pre-pulse and a 135 degree recollection pulse it is possible, by suitably controlling the inhomogeneity, to cause selectively either mirror or stimulated echoes to be manifested. Specification 795,057 is referred to.

Title: Improvements in negative-feedback amplifiers
IPC: H03F1/50
Filed: 1947-07-25
Abstract: 626,191. Valve amplifying circuits. WESTERN ELECTRIC CO., Inc. July 25, 1947, No. 20135. Convention date, Jan. 12, 1943. [Class 40 (vi)] A negative feedback amplifier, unconditionally stable for low gains, is provided with a network including a current dependent resistance so that the sing current developed at higher gains flowing in the resistance modifies the characteristics of the feedback loop to limit the sing current to an unobjectionably low value. As shown, the second and third valves 2, 3 of a three-stage amplifier are coupled by a bridged-T network 8 and negative feedback is provided by a network 6. The shunt arm 20 of the bridged-T network is formed by a thermistor or other current variable resistance, which is heated by the high-frequency sing current flowing in it, thus changing the characteristics of the interstage coupling 8. In a modification, part of the anode current of valve 1 may be tapped off and used as a bias to heat the thermistor either directly, Fig. 2 (not shown), or indirectly, Fig. 3 (not shown). In another modification, Fig. 4 (not shown), the thermistor is heated by current derived from the feedback network through a network, so as to attenuate frequencies near the upper end of the useful 'band and thus ensure against operation by any save the sing frequency. Specification 514,567 is referred to.

Title: Improvements in thermally-actuated electric switching arrangements
IPC: H01H61/08
Filed: 1948-04-19
Abstract: 692,017. Thermal switches. BADER, K. E. Sept. 30, 1948 [April 19, 1948], No. 20142/52. Divided out of 691,961. Class 38 (v) A switching apparatus adapted to control the supply of energy to a heating apparatus by intermittently interrupting the current, has a U-shaped bimetallic element 13 anchored at one end, a switch unit 12 having an actuating pin 14 co-operating with the free limb of the bimetallic element, a heater coil for the element and a variable resistor in parallel with the heater. In the arrangement shown, the heater coil is wound on the bimetal 13 and the parallel combination of heater coil and resistance is connected in series with the switch contacts and the apparatus to be controlled. The variable resistor comprises a fixed resistance element 25 and a rotary spindle 18 carrying an adjusting knob 11 and a spring biased plunger 19 with a contact roller 26 engaging the resistance 25. In the "full on" position the plunger 19 engages a contact finger 20 to short circuit the heater coil. When the contact roller 26 is in an intermediate position, current flowing in the heater coil causes the bimetal 13 to relax its pressure on the actuating pin 14, so allowing the switch 12 to open to interrupt the circuit. The bimetal then cools and recloses the switch and the cycle is repeated. The adjustment of the variable resistance varies the current in the heater coil to determine the ratio of the "on" time to the total time and so determines the average power supplied to the controlled apparatus. Specification 691,961 is referred to.

Title: Improvements in processes for the manufacture of alumina
IPC: C01F7/0613
Filed: 1949-08-08
Abstract: Material intended for the extraction of alumina by concentrated alkaline lyes is produced by introducing ferrous or ferroso-ferric oxide into a siliceous aluminous starting material, e.g. bauxite, in quantity at least sufficient to fix, as a product insoluble under extraction conditions, the silica which would otherwise combine with the alumina or the base metal of the alkaline lyes, and calcining at a temperature sufficient to ensure the combination of the silica and the said oxide.  Alternatively, in the preparation of material intended for the extraction of alumina by water or dilute alkaline lyes, ferrous or ferroso-ferric oxide is added to a siliceous aluminous material, e.g. schist, clay, clinkers or slag, which either contains lime or to which lime, say as calcium carbonate, is added, in amount indicated above, allowing also for the silica which would otherwise combine with the lime, and calcining as before, e.g. at 1300-1400 DEG C in a neutral atmosphere.  Material capable of forming ferrous or ferroso-ferric oxide in situ, e.g. ferric oxide, or alkali metal or alkaline earth metal ferrite, may alternatively be used, especially when the aluminous materials treated contain reducing agents, e.g. sulphides present in the slag.  The iron oxides, whether simple or compound, may be added to the aluminous material in a state of fusion, e.g. slag as discharged from iron blast furnaces.
