Abstract: ABSTRACT OF THE DISCLOSURE         A system and method for the handling of solid waste involving multiple solid waste handling stations.  Each station has a hopper unit for receiving waste, a storage unit, and a compactor unit for transferring and compacting the waste.  Each station is provided with detector means for detecting a packed storage unit.  Adjoining stations are operatively interconnected by station selector means.  The station selector means responds to the detector means to deactivate a station having a packed storage unit and to activate an adjoining station having an empty storage unit.

Abstract: VALVE SEAT CONCENTRICITY GAGE            ABSTRACT OF THE DISCLOSURE A gage is disclosed which produces air flow signals corresponding to the eccentricity existing between the centerline  of the valve stem hole and the valve seat, the eccentricity reading being unaffected by out-of-round, out-of-square or irregular surface finish conditions. The gage includes an arbor centered within the stem hole and an air spindle member having an internal passage through which the arbor extends, the air spindle having a partially spherical surface formed thereon located to contact the valve seat.  A pair of opposed orifices exiting into the internal passage are located at axial points even with the theoretical center of the partially spherical air spindle surface and combined with an appropriate air pressure source and readouts such that the total flow out of each orifice can be measured and a corresponding readout obtained, the orifice locations being such that out-of-square conditions do not affect eccentricity readings and the centering characteristics of the spherical surfaces removing the effects of out-of-round and localized valve seat surface variations.  A valve seat surface condition gaging arrangement is also included in the combination consisting of a ball jet type air gaging arrangement carried by the air spindle comprising a ball recessed within an opening and located so as to allow content of the ball with the valve seat.  Rotation of the air spindle with respect to the valve stem accordingly gives an indication of the eccentricity of the valve seat with respect to the valve stem and also indicates localized variations in the surface condition of the valve seat, both of which conditions are uninfluenced by out-of-square conditions between the stem hole and the valve seat.

The compounds are pharmacologically active substances which are distinguished more especially by the fact that they possess a pronounced anti-inflammatory activity, are well tolerated by the stomach and have only a relatively low toxicity.  In addition, these compounds are frequently distingu-ished by the fact that their action commences rapidly and is of high intensity and of long duration; they also have a favourable resorbability, and a relatively good stablility in galenical formulations.

Abstract: ABSTRACT OF THE DISCLOSURE      A device for the magnetic treatment of water and other liquids, having a pair of concentric tubular casings which are spaced from each other so as to form an annular treatment chamber. The inner casing contains an elongated magnet having two or more longitudinally spaced poles, and the outer casing is made of a magnetic material which serves to concentrate the magnetic lines of force within the annular chamber.  The inner casing is supported within the outer casing by means of elastic, non-magnetic sleeves which are positioned over opposite ends of the inner casing and compressed between it and the inner surface of the outer casing so that the treatment chamber is rendered fluid-tight and the inner casing and magnet are prevented from shifting longitudi-nally with respect to the outer casing.    The device is manufactured by pressing resilient end caps on opposite ends of the magnet and pressing this assembly into the inner casing, inserting the inner casing in the outer casing and then wedging the sleeves between them.

Abstract: ABSTRACT OF THE DISCLOSURE        The invention relates to bottle feeding apparatus in which milk, beverage or like bottles which are moving continuously in upright position in single file along a path are selectively deflected out of said path.  The apparatus is particularly suitable for selectively rejecting from a high speed bottling line conveyor those bottles which an inspection apparatus has detected as being dirty or con-taining foreign bodies. The apparatus comprises means for deflecting the mouth of a faulty bottle transversely of the direction of its forward movement to tilt the axis of the bottle, the neck of a deflected bottle being engaged by a plough, positioned adjacent to and downstream of the deflect-ing means, which is shaped progressively to displace the bottle sideways out of the stream of moving bottles.  As a deflected bottle is moved sideways out of the stream it is guided by the plough into a deflection channel and its axis is restored to an upright position by its neck engaging with a rail at the opposite side of the deflection channel and by the squeezing action of adjacent bottles.  A second deflecting means may be selectively brought into operation during starting up or slow running of the conveyor to compensate for the differences in conveyor speeds and ensure rejection of only those bottles detected as faulty.

Abstract: Abstract A method of compacting powder comprising interweldable particles into a solid body by using, a shock wave. The shock wave has such an amplitude that interwelding of the particles in the powder is obtained. The shock wave is generated by impact of either a body launched against the powder or by a  capsule containing the powder, which capsule is launched against a support instead of the body. The velocity with which the body or the capsule is launched amounts to 300 to 2000 m/sec. The duration of the compacting pressure following behind the shock wave is determined by the chosen length and the chosen impedance of said body or said  capsule and said support. The shock wave is chosen such that it propagates through the powder with a rise time being shorter than the time necessary for obtaining equalization of the overall temperature. The compacting pressure must be maintained so long that the welds on the surfaces of the powder particles solidify.
