Abstract: ABSTRACT OF THE DISCLOSURE The method for the electropneumatical testing of the composite wrapper of filter cigarettes by applying a controlled-flow gas pressure to a cigarette end, comprises a first testing in order to determine the gas permeability of the cigarette along its longitudinal direction, i.e. the gas permeability of the filter and of the tobacco filler, in which the cigarette end opposed to the end to which the gas pressure is applied is maintained open and the outer surface of the tipping band is sealed in a gas tight manner; a second testing in order to determine the gas permea-bility of the paper wrapper which envelopes the tobacco filler, in which the cigarette end opposed to the end to which the gas pressure is applied is closed in gas tight manner, and the outer surface of the tipping band is sealed in a gas tight manner; a third testing in order to determine the gas permeability of the whole composite wrapper in which the cigarette end opposed to the end to which the gas pressure is applied is closed in a gas tight manner. The signals obtained as a result of the second and third testing are compared with respective levels of acceptability presenting a determined value beyond which a cigarette is not acceptable. The value of acceptability is determined for the second testing as a function of the signal obtained from the first tecting, and for the third testing as a function of the signals obtained from the first and second testing.

Abstract: IMPROVEMENTS IN CLUTCH AND BRAKE MECHANISM     Abstract The disclosure provides for a number of improvements in a brake-clutch mechanism wherein a drum is carried on the drive member for driving engagement by clutch shoes carried by the driven member.  The clutch shoes are normally biased into driving engagement with the drum and a brake band is utilized to move the clutch shoes out of engagement with the drum and to stop rotation of the driven member without interrupt-ing the rotation of the drive member.  The improvements relate to a higher torque capability for the mechanism, the exclusion of foreign matter from the mechanism, the mounting for the brake band, the use of the brake band to aid in keeping the braking surfaces clean, and provision for cut-off of the power source in the event the brake band should fail.  The disclosure further contemplates a novel arrangement for driving and controlling the chain sprocket of a chain saw.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a novel power drive assembly for use with a prime mover.  The assembly comprises a rotatably supported first shaft and a rotatably supported second shaft spaced from the first shaft and parallel thereto.  A pair of pulleys are provided and the position of the second half portion of the driving pulley relative to the first half portion is fixed by a feedback loop.  The driving pulley is utilized as the driven pulley and the  driven pulley is utilized as the driving pulley.  The prime mover is of the type where rotational speed varies over wave ranges.  The feedback loop comprises a sensor which senses the rotational speed of the driven pulley and supplies an output to a comparator means which compares the output of the speed sensor with some reference signal which is related to the desired rotational speed of the driven pulley.          The comparator circuit generates a signal to vary the effective pitch diameter ratio between the driving and the driven pulley which is applied to the power means on the driven pulley so that the output signal from the speed sensor is equal to the reference signal.  This produces much  more efficient assembly in view of the prior art.

Abstract: ABSTRACT OF THE DISCLOSURE                ELECTROMAGNETIC FUEL INJECTOR    A high flow rate electromagnetic fuel injector valve with a rapid response time is disclosed for utilization in electronic fuel  injection systems.   The  fuel injector valve comprises a stator means and a valve assembly having a self-centering valve member reciprocally mounted in a valve housing.  The valve member consists of a ball valve with a semispherical sealing surface connected by a stem to a magnetically attractable cup-shaped armature.   The armature is preferably coated with a friction reducing material where it slideably contacts an armature guide bore of the injector valve during its reciprocation.  The ball valve of the valve member obturates an exit orifice of the valve housing by sealing against a conical valve seat which has been coined to receive it.  Adjacent to the ball valve and conical valve seat interface are vortex generating and metering orifices for the tangential entry of fuel into a swirl chamber of the valve housing.  The positioning of the metering orifices, which are precisely sized by ballizing to control flow rate, is used to regu-late the injector spray angle generated by the vortex of fuel entering the swirl chamber.  The conical surface of the valve seat produces vortex amplification to further increase the swirl effect caused by the positioning of the entry orifices.

Abstract: ABSTRACT         There is provided an apparatus and method for selectively coiling a transfer bar or allowing the bar to pass uncoiled through the apparatus.  A frame supports a number of rollers which can transfer a bar in one direction, and conventional bend roller means are located above the rollers, adapted to apply a down curvature to a transfer bar.  Pivotal ramp means upstream of the bend roller means can either direct a transfer bar through the bend roller means, or allow the transfer bar to pass along the rollers under the bend roller means.  A sub-frame downstream of the bend roller means carries at least one roller, and is mounted for movement between a raised position and a lowered position.  In the raised position, the roller on the sub-frame defines,with a further roller upstream thereof and with a coil-guide roller located under the bend roller means, a cradle in which the initial convolu-tions of a coiling transfer bar can be contained.  Initially, the sub-frame is in its uppermost position, to receive the initial small convolutions of a coiling transfer bar.  As the transfer bar continues to coil and becomes heavier and larger in diameter, a point is reached where the sub-frame can be lowered, thus allowing a greater coil radius to be accommodated in the cradle.

Abstract: ABSTRACT:       A plasma reactor, in which particulate matter is caused to interact with low temperature plasma (i.e. below 100,000 K) comprises spaced stationary electrode structures 2, 11 of which at least one is annular, between which an arc or arcs 7 is established by a power supply which may include a thyristor (SCR) 9.  The arc is pulsated and caused to orbit or circulate round the or each annular electrode structure to form a conical plasma zone between the electrodes, while particulate solids are introduced through inlets 5 to enter the plasma zone and interact with the plasma therein. Extended dwell periods and highly effective interaction are brought about by circulation and pulsation of the arc and a high particle population density.   The arc can be circulated at high speed by electrical means, for example by sequential energization of plasma torches 1 in an annular array or of the segments 8 of a segmental anode, or by electromagnetic circulation of the arc attachment round an annular cathode or round a segmental anode with the help of coils 10 fitted between the segments. Examples of reactions that can be efficiently conducted by this method include the reduction of metal ores, beneficiation of low grade chromite ores, recovery of energy values from low grade carbonaceous matter such as colliery wastes and the formation of pozzolanic material and cements from siliceous minerals.
