Title: Improvements relating to the replacement of packages on textile winding devices
IPC: D01H9/02
Filed: 1957-08-29
Abstract: 841,032. Wound packages replacement methods. VEREINIGTE GLANZSTOFF FABRIKEN A. G. Aug. 29, 1957 [Sept. 15, 1956], No. 27255/57. Class 120(2). In a method of replacing packages on textile winding devices having a plurality of working spindles to which thread is supplied during the changing operating at a constant delivery speed, the thread, after being separated from a package, is supplied to a rotating tube mounted on a travelling auxiliary spindle, and is wound with traversing on the empty tube during the removal of the package, the tube thereafter being transferred from the auxiliary spindle to a working spindle while both spindles are running. Thread being fed continuously at constant speed is severed from a full package on a rotating spindle 13 and applied to a tube 10 driven by a motor through a clamping means 8. The yarn is traversed by an auxiliary traverse 9 also driven by the motor and the movable tube 10 is brought into axial alignment with and raised up to the rotating spindle 13 by means of the motor. The spindle 13 pushes a rod 17, Fig. 5, to release clamping jaws 20. A rubber pad 21 on the rod 17 ensures that the spindle 13 and tube 10 are rotating at the same speed and when the drive of the tube 10 has been taken up by the spindle 13 the auxiliary driving means is withdrawn both vertically and horizontally to be used at another winding station when required.

Title: Improved process for the destructive distillation of coal
IPC: C10B1/04
Filed: 1937-10-11
Abstract: 501,374. Carbonizing processes. NATIONAL FUELS CORPORATION. Oct. 11, 1937, No. 27619. Convention date, Oct. 24, 1936. [Classes 55 (i) and 55 (ii)] In the destructive distillation of coal by passing it through three zones 4, 5, 6, in the first of which it is heated to a temperature at which distillation begins and in the last the distillation is completed to the desired degree, the temperature in the second zone reaches 500-600‹ C. and the heating herein is effected at a rate sufficiently low to avoid undue swelling by means of hot non-reactive gases passing in counter-current therethrough. The preferred heating rate in the second zone is such as to give a temperature gradient of a straight line order and is .obtained by controlling the amount of heating gas passing therethrough and the rate of flow of the fuel ; an example specifies a rate of heating of 2 to 4‹ C. per minute. The preferred temperature ranges in the other zones extend up to 300-350‹ C. in the first zone; and up to 700-1000‹ C. in the third zone ; a final cooling zone 7 may also be arranged. Although the plant shown comprises a single vertical retort 1 with physically separate zones each having separate gas heating circuits, a single undelimited retort could be used or a separate retort for each zone ; fathermore, a single gas circuit could be used. The final distillation zone 6 is heated by burners 9 supplied with lean gas from a receiver 26 and air, part of the burnt gases entering the zone through apertures 15. A part of the lean gas may enter the cooling zone through pipe 16. Part of the gas from the zone 6 enters the distilling zone 5 directly and the remainder flows through the closed circuit including a heat exchanger 20, pump 24, condenser 22, tar extractor 25, and receiver 26. The higher calorific gas obtained in zone 5 mixed with some of the lean gas from zone 6 is used for the heating gas in this zone, the temperature of the mixed gases being controlled by the heat exchanger 20 and the circuit also including a condenser 34, tar extractor 37, pump 36 and gas receiver 38. The preheating zone 4 is heated by another part of the lean gas, introduced to this circuit through pipe 54, mixed with vapours from this zone, the mixed gases being heated in an exchanger 48 by a burner 50 supplied with combustion gas through pipe 49, the circuit also including a condenser 47 and a pump 45. Slack coal may be used, preferably briquetted with sulphite liquor, starch, coal tar or pitch. A smokeless fuel resembling anthracite is obtained besides organic condensates and two gas mixtures of greater and less calorific value respectively. Specification 340,717 is referred to.

Title: Amplifier circuit for transmission lines
IPC: H03F3/62
Filed: 1972-06-13
Abstract: 1393384 Directional switching system LORAIN PRODUCTS CORP 13 June 1972 [28 June 1971] 27638/72 Heading H4R In a amplifier system which may be switchable to amplify signals in either direction on a 2 wire line between stations 10 and 11, a first amplifier 13 is fed from the signal across the line and injects its output in series with the line while a second amplifier 15 is fed with the signal developed by the signal current flowing along the line and feeds its output across the line, direction switching may be effected by determining the direction of signal flow in the line and appropriately changing the amplifiers 13 and 15 so as to be respectively phase maintaining or phase inverting, according to the direction of current flow in the line, to provide amplification in the appropriate direction. With transmission taking place from station 10 to station 11, the signals appearing across transformers 14 and 16 are in phase and these signals are added at the input of amplifier 40 and subtracted at the input of amplifier 41, providing a large negative signal output at terminal 40c and no output at terminal 41c, this condition causing opening of the gates 83 and 87 on the non-inverting inputs of amplifiers 13 and 15 and amplification of the signal in the direction from station 10 to station 11. With transmission from station 11 to station 10 the signals appearing across transformers 14 and 16 are in antiphase and they therefore cancel at the input of amplifier 40 and add at the inputs of amplifier 41 causing a positive output at terminal 41c and no output at 40c, this condition causing opening of gates 84, 88, on the inverting inputs of amplifiers 13 and 15 and amplification of the signal from station 11 to station 10. In a modified system, Fig. 2 (not shown), the input to the amplifier 13 is taken, via a differential amplifier, from directly across the line rather than via the transformer 16, the same signal also providing the input to the direction switching detector. The arrangement allows use of a smaller capacitor 17 which, if too big, can cause cross ringing, dial pulse distortion, and premature operation of the trip relay. Both systems provide stabilization of the impedance presented by the amplifier system input with variation of the impedance connected to the amplifier system output.

Title: Improvements in or relating to automatic voltage and current control systems
IPC: G05F1/38
Filed: 1959-08-13
Abstract: 902,467. Automatic voltage and current control systems. NORTH ELECTRIC CO. Aug. 13, 1959 [April 6, 1959], No. 27686/59. Class 38 (4). An automatic control system wherein a load is supplied from an alternating current source by way of a main transformer and a booster transformer has regulating means including saturable reactors to maintain the load voltage constant over the normal range of load current and which cause the load current to be decreased abruptly for current in excess of the normal range and to maintain the load current constant. The arrangement of the saturable reactors is such that in a polyphase system the system is kept substantially balanced. A load 13 is supplied from a three-phase source 30 by way of main transformers 21, 23, 25, booster transformers 15, 17, 19 and a three-phase rectifier 10. The voltage across the load 13 is fed to parallel circuits comprising on one hand a rectifying diode 94, a PN junction constant voltage reference diode 95 and a resistor 96 and on the other hand resistors 91, 93 and potentiometer 92. The control winding 83 of a magnetic amplifier is connected between these parallel circuits such that deviations of the load voltage relative to the constant reference voltage of the diode 95 causes variations in the control current in the winding 83 and thus in the impedance of the impedance windings 81, 82 of the magnetic amplifier. Thus, the voltage developed across a resistor 84 varies which in turn varies the current supplied to the control windings 42, 52, 62 of the saturable reactors 32, 33, 34. These saturable reactors are associated with the primary windings 16, 18, 20 of the booster transformers and thus the amount of boost supplied by these transformers is controlled to keep the load voltage constant within a given range of load current. Should the load current rise to a value outside this range the voltage output of a rectifying bridge 99, which is under the control of a saturable reactor 100, will become greater than the constant reference voltage of the diode 95. A transistor 105 will thus be made conductive, thereby causing an abrupt increase of the current flowing in winding 83 which varies the current flowing in the control windings 42, 52, 62 of the saturable reactors 32, 33, 34 so as to reduce the output voltage of the rectifier 10 and thereby limit the load current. The circuit of each of the primary windings of the booster transformers includes the impedance windings of one of the saturable reactors 32, 33 or 34 and balancing windings on each of the three saturable reactors 32, 33, 34, whereby the system is maintained in balance.

Abstract: 1,010,282. Forming pellets. NATIONAL FROST PROTECTION CO. Inc. July 15, 1963, No. 27987/63. Heading B5A. Pellets are formed by introducing moulding material 15 between two externally co-operating contra-rotating rollers 20, 21, the intermeshing ribs 22, 23, of which, force the material through apertures 45 in each valley, into the interior of the rollers where the issuing ribbons are cut to the required length by suitably disposed knives (not shown). Each aperture 45 is lined with a sleeve 46 having a tapered bore, as in Fig. 6, so that upon movement through the bore the material is progressively compressed. The ribs of each roller are of a herring-bone configuration, as in Fig. 5, and the rollers are rotated in such a direction that the edges of the ribs co-operate before the central portions, i.e. the apices of the herring-bones. The material is thus confined within a central compression area and is not extruded from the side of the valleys. An alternative construction of the rollers is given in Figs. 7 and 8 (not shown).
