Title: Improvements in or relating to machines for producing a continuous wrapped tobacco rod
IPC: A24C5/18
Filed: 1961-09-07
Abstract: 1,041,553. Cigarette-making machines. MOLINS ORGANISATION Ltd., and D. W. MOLINS. Sept. 6, 1962 [Sept. 7, 1961], No. 32115/61. Heading A2C. In a continuous rod cigarette-making machine as described in Specification 1,041,551 and 1,041,552 the continuous tobacco stream formed on the second conveyer band is compressed, and means are provided to detect variations in the air permeability of the compressed stream, which means controls a trimming device which removes surplus tobacco from the stream, the stream being subsequently wrapped. The continuous tobacco stream formed on the air-pervious band 13 is compressed by a rotatable paddle wheel 33 fitted with yieldable paddles 34 arranged tangentially from its boss 35 and moving at the peripheral speed as the air-pervious band 13; alternatively the tobacco stream may be compressed by an endless conveyer band, spring-loaded to press against it (Fig. 3 not shown). Surplus tobacco is then removed from the compressed stream by trimming discs 24, 25 mounted on vertically sliding spindles 26, 27 to vary their distance from the band 13 and accordingly the amount of tobacco trimmed from the stream. To this end an air cell 28, connected to suction via a pipe 29 and located within the suction chamber 20 drawing air through the band, measures the air permeability of the compressed tobacco stream and communicates via a duct 30 with a control unit and hydraulic amplifier of the type disclosed in Specification 929,338 which operates to raise or lower the discs 24, 25 accordingly, and ensures that the tobacco stream contains a substantially constant quantity of tobacco per unit of time.

Patent GB-992828-A (GB)
Title: Improvements in or relating to inverters
IPC: H02P27/04
Filed: 1963-07-31
Abstract: 992,828. Inverting. M. ETTER. July 31, 1963 [Aug. 13, 1962], No. 30315/63. Heading H2F. A converting arrangement comprising series thyristors 5, 6, shunted by reverse diodes 3, 4, and disposed across a D.C. supply, includes an arrangement to extinguish the conducting thyristors. As shown in Fig. 1 a 3-phase supply for a motor M is derived from a D.C. supply at ab through a polyphase bridge arrangement, the frequency of the firing pulses and the duration of the conducting periods of the thyristors being variable to vary the frequency and amplitude of the output. In order to extinguish all the conducting thyristors these are all fired simultaneously causing a capacitor 16 in a resonant circuit 16, 17 to become reversely charged. When this capacitor discharges again it causes a reverse current through the thyristors to extinguish these. In order that the short circuit occurring when all the thyristors fire may not cause excessive current, the primary winding 9 of a transformer 10 is included in the D.C. line; the secondary winding 11 of the transformer is in series with a diode 12 which prevents secondary current on rising forward line current so that the winding 9 behaves as an inductor. After the thyristors are blocked current in the motor continues through the diodes 3 and 4 flowing in the reverse sense through the supply ab; thus the current in the winding 9 is reversed tending to cause an overvoltage, but this is prevented by the presence of the secondary winding 11, secondary current flowing back to the supply through the diode 12. A further protective circuit comprises a capacitor 18, diode 15, inductance 13 and resistance 14. The resonant circuit 13, 18 has a period twice that of the circuit 16, 17 so that the capacitor 18 is discharged when the thyristors are extinguished. This arrangement limits the voltage arising across the series thyristors. In a further arrangement (Fig. 3) by which A.C. may be supplied to a resistive load 19 or by which current may be supplied in either direction to a reversible D.C. motor, the centre tap of a D.C. supply is earthed as is one end of the load 19 whose other end is connected to the junction of thyristors 5, 6. A capacitor 22 is charged through a diode 35. To extinguish a conducting thyristor a further thyristor 24 is fired allowing the capacitor 22 to discharge through an inductor 23 with which it forms a resonant circuit. The inverse voltage produced extinguishes the thyristor and the thyristor 24 is extinguished by its own resonant circuit 25, 26. Inductors 27, 28 shunted by resistors 29, 30 are provided to prevent rapid current rise, and diodes 31, 32 are provided for reverse supply to the load. A modification of the connections of thyristors 5, 6, and diodes 3, 4, which includes additional diodes is disclosed (Fig. 4, not shown).

Filed: 1970-07-07
Abstract: 1311492 Fluid-pressure servomotor systems ATLAS COPCO AB 7 July 1970 [17 July 1969] 32923/70 Heading G3P A motor-driven compressor has a power control mechanism 2, such as a fuel-injection pump, coupled to an adjusting means 40 operated through a device 49 when the pressure at the delivery side of the compressor rises above a predetermined value. The motor 1 drives low and high pressure stages 7, 8 through a shaft 6 and gearing 9 and has its output increased when a lever 3 is rotated anti-clockwise by fluid-pressure derived from the inter-stage connection 14 and applied through a pipe 46 to a spring-loaded piston comprising the means 40. The opposite side of the piston is connected by a pipe 48 and a spring- loaded ball valve 59 with the receiver 20 and with a spring-loaded resilient diaphragm for actuation of a valve 68 which causes actuation of a further valve 32 when it moves downwardly to connect a chamber 80 to receiver pressure. With the motor idling and the compressor unloaded to atmosphere through a valve 36, a spring-loaded valve 26 is operated manually to allow oil pressure from a pump 23 to pressurize a chamber 30 and lift the valve 32 to a position in which a pipe 94 is isolated from a pipe 86 communicating with a vent 87 so that a piston 33 is moved to the right against a spring 35 by the depression in the intake 10 to the compressor. This movement opens a butterfly valve 12 and closes the valve 36 so that the pipe 46 receives fluid under pressure from the inter-stage connection to operate the means 40 and a diaphragm valve 88 which closes the vent 87 and allows inter-stage pressure to be applied through an aperture 89 to the piston 33. If the receiver pressure rises due to compressor delivery exceeding demand, the valve 59 is lifted to allow receiver pressure to act through pipes 50, 53 and 48 on the means 40 reducing the speed of the motor and on the diaphragm 66 to restore the valve 32 to its original position.

Abstract: 342,311. Spray carburetters. LOCK, R. P., 4, High Street, Rainham, Kent. Oct. 30, 1929, No. 33015. [Class 7 (iii).] A bi-fuel jet carburetter of the type in which the change over from one fuel to the other occurs at a given throttle setting, means being however provided to enable one fuel to be used when desired at all throttle settings, is provided with a plurality of jets for at least one of the fuels. In the carburetter shown, petrol is supplied from a float chamber to a pair of jets, one of which is shown at 9, Fig. 4, the other forming a slowrunning jet opening into a chamber 64. Paraffin is supplied from a second float chamber to a second pair of jets, one being shown at 10. The supply of petrol to the jets 9 is controlled by spring-closed valves 11, which are actuated by a vertical pushrod 30, Fig. 6, which depresses a pivoted member 25 carrying arms 21, 22, which engage collars 19 on the valves. The supply of paraffin is controlled by valves 12 similarly operated by a vertical push-rod 31, Fig. 1. The push-rods 30, 31 are operated by means of cams 33, 34 on the spindle of the throttle. These cams coact with tappet arms 35, 36 carried by a rocker 37 pivoted at 38 to the carburetter body, and the arms 35, 36 in turn actuate tappets 40, 41 carried by spring- pressed sleeves 42, 43. Extensions 48, 49 on these tappets engage the heads of the push-rods 30, 31. The rocker 37 carries a spring-pressed knife-edge 57 engaging a fixed knife-edge 58, which causes the rocker to move with a quick " snap " action at a given throttle setting to change over the fuel supplies. The extensions 48, 49 of the tappets 40, 41 are stepped, and the tappets themselves are pivotally mounted on the sleeves 42, 43 so that by slightly rotating them the stepped extensions 48, 49 may be moved to a position in which they maintain the push-rod 30 permanently depressed and the push-rod 31 permanently raised, thus allowing the use of petrol at all throttle settings. The tappets 40, 41 are rotated for this purpose by means of a Bowden cable connected to an arm 55 on the tappet 40, a rod 54 connected to arms 50, 51 on the tappets causing a similar movement of the tappet 41. The air inlet 4 is supplied with exhaust gases or exhaust heated air by means of an injector 62, in order to prevent knocking when paraffin is employed.
