Patent GB-101375-A (GB)
Title: Improvements in Machines for Spooling Yarn or Thread.
IPC: B65H54/74
Filed: 1916-03-13
Abstract: 101,375. Dewhurst & Sons, J., and Preston, W. March 13, 1916. Thread-spooling machines.-In order to enable the spooling of a desired length of thread &c. to be completed close to the flange where the nicking and ending operation is carried out, means is provided whereby the drive from the spindle gearing shaft to the traverse screw or equivalent shaft can be interrupted, and an independent traverse be given to the thread-guides to any desired point on the barrel of the spool &c. before spooling is resumed. During spooling, the spindle drive shaft 14 is clutched to a co-axial shaft 16 geared to the usual traverse screw shaft 17. The clutch parts 15, 15<a>, the latter of which is splined on the shaft 16, are normally held in gear by a spring-controlled lever 23 locked by a notch in a cam 25 engaging a bowl 26 on the lever. When spooling is completed and the change is in operation, the shaft 9 is given a complete revolution during the nicking and ending operation. The lever 23 is moved by the cam 25 to carry the clutch part 15<a> into engagement with a part 15b loose on the shaft 16. An adjustable tappet 13 on the shaft 9 subsequently releases a spring locking-catch 11 and allows a spring 10 to move a lever 5 and carry a clutch part 3<a> splined to the driving-shaft 2 into engagement with a part 3 carrying a sprocketwheel, which drives by a chain a sprocket-wheel 20 on the part 15<b>. The traverse screw 17 is thereby driven in the reverse direction through the shaft 16 and gears 18 until a stud 8<a> on a disk on the shaft 9 forces the lever 5 over to disengage the clutch 3, 3<a>. The catch 11 automatically resets itself. Shortly afterwards, the notch in the cam 25 comes opposite the bowl 26, and the spring 24 draws over the lever 23 and clutch part 15a. The tappet 13 being adjustable on the shaft 9, the driving interval can be adjusted to give the necessary movement of the thread-guides. Specifications 21784/05 and 7685/11 are referred to.

Abstract: 646,354. Frequency modulation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 16, 1945, No. 4024. Convention date, Nov. 29, 1943. [Classes 40 (v) and 40 (vi)] An apparatus for driving a mechanical system having mass, stiffness and resistance with velocity proportional to a control voltage, comprises means for deriving three voltages or currents linearly related to the control voltage, the time integral and the time derivative of the control voltage respectively and utilizing these voltages or currents to drive the mechanical system. A diaphragm 1, Fig. 1, having mass m, mechanical resistance r and stiffness s is driven with velocity v(t) by a coil 7 connected to the common load resistance 19 of three amplifying valves 13, 15, 17. A control voltage e(t)=k. v(t) is applied to terminals 3, and output of an integrating network 33, 35 is applied through resistance 21 to valve 13. A portion of the input voltage is applied through an attenuator 37, 39 and resistance 23 to valve 15, and the output of a differentiating network 41, 43 is applied through a resistance 25 to the valve 17. The taps on resistances 21, 23, 25 are adjusted so that the voltage appearing across resistance 19 and hence the current in coil 7 and the force on diaphragm 1 are proportional to s#v dt+r v+m dv/dt, resulting in the desired motion of the diaphragm 1. In a modification, Fig. 2, the diaphragm 105 of a variable capacity modulating unit 101 is driven with substantially constant velocity throughout the whole of its amplitude by a winding 107, which is fed by an amplifying valve 151 through a matching transformer 111. The input to network 113 is provided by a tap on a voltage divider 114, one end of which is periodically connected to ground through a cam-driven switch 115, the other end being connected to the H.T. supply B+. The input is a square wave voltage varying between the H.T. voltage applied through the lower part of resistance 114 and a lower value. Network 113 comprises an integrating network 137, 139, and a differentiating section comprising condenser 143 and resistances 129, 131, 133, 135 is connected to the tap on resistance 114 through a network 145, 147 which reduces the slope of the square-wave input. The output of the integrating section 137, 139 is connected to resistances 133, 135 through a condenser 141. The input to amplifier 151 is taken from a tap on resistance 129 and contains the outputs of both the integrating and differentiating sections in proportions depending on the position of the tap on resistance 129, being of the form shown in Fig. 6. The output of the amplifier is of the same form but greater amplitude, and produces the desired motion of the vibrating diaphragm 105.

Abstract: 685,182. Making pipes &c. DEUTSCHE EDELSTAHLWERKE AKT.-GES. Feb. 20, 1951 [March 1, 1950], No. 4135/51. Classes 83 (i) and 83 (ii). Casting.-In a method of casting a hollow article, metal is introduced into the space between an outer mould wall and a core and is heated by an electric current therein so as to be brought to or maintained at a sufficiently fluid state completely to fill the space. The metal may be introduced in solid form, that is as powder, as turnings, shavings and like scrap or as sheet or the like and may be pressed to a shape corresponding roughly with the mould space or may be introduced in molten form and further heated to increase its fluidity. The heating is by high-frequency induction or by conduction through the metal itself or both. Sand or other readily removable material is preferably used for the core. The outer wall of the mould may be of metal, ceramic material or of moulding sand and in the latter case may be supported by a jacket in the form of a non-magnetic split metal tube. The mould may be rotated about its axis during casting and a neutral or reducing atmosphere may be maintained above the molten metal. Fig. 6 shows a form in which the mould is filled by bottom pouring from a runner 10, further heating of the molten metal as it rises being by a high-frequency coil 3b or by the direct passage of electricity from an annular electrode 5a which'rises with the metal, the second lead-in being at the bottom of the mould. The mould wall may comprise a metal tube which becomes heated sufficiently to cause the cast metal' to weld to it, thus forming a composite tube or the like. A tubular bloom may thus be produced, the inner cast material being one which is difficult to work alone, for example acid resisting alloy steel, but which may, however, be worked in the form of a lining and the outer layer may later be removed by mechanical working or by dissolving in acid.

Abstract: 490,058. Automatic selectivity, tuning, and volume control. KRAMOLIN, L. L. DE. Feb. 11, 1937, No. 4141. Convention date, Feb. 11, 1936. [Class 40 (v)] In an arrangement for effecting automatic control of the selectivity tuning or volume in radio apparatus in which a deviation from a predetermined state produces a correcting effect, an after-effect phenomenon is used to produce a further correction after the deviation is so reduced as to be ineffective to produce true correction. The after-effect may be magnetic or electrostatic hysteresis, applied to the inductances or capacities described in Specifications 449,240 ; 451,097, [Group XXXVI], 451,098, 455,190, and 473,384; or a mechanical effect realised by a friction brake. The Specification as open to inspection under Sect. 91 comprises also an automatic tuning circuit in which a resonant circuit L1, L2, C1 feeds an amplifier R1, which is coupled by a transformer Tr to the series - connected condenser C2 and resistance W, the signal amplitude across which is kept constant by a neon tube R2. The voltage developed across the resistance W is therefore dependant wholly upon the signal frequency and is rectified by the rectifier G and fed to a winding M controlling the saturation of the core of the inductance L2. The tube R2 may be omitted if the circuit C2, W is fed from an amplifier provided with A.V.C. This subject-matter does not appear in the Specification as accepted.
