Patent EP-0086240-B1 (EP)
IPC: E01C23/12
Filed: 1982-02-11
Granted: 1985-11-06
Abstract: A pavement breaker including a mobile carrier vehicle is disclosed. A beam (38) is provided having a resonant frequency with a pair of nodes spaced from the input and output ends of the beam and anti-nodes at each end and at the center. An oscillator (46) is fixed to the input end of the beam to vibrate the beam at at least near its resonant frequency. The beam is mounted to the carrier vehicle at the node near the input end of the beam, A weight (54) is superimposed over the beam at the node near the output end and has a bearing surface adapted to bear downwardly against the beam at that node. The weight is coupled to the vehicle to control the vertical position of the weight. A tool (76) depends from the output end of the beam, and strikes surface (22) on which the vehicle rests at the vibration frequency of the beam as the tool vibrates responsively to vibrations of the beam. The reaction force generated by the tool is substantially absorbed by the weight and not transmitted to the carrier vehicle. The tool is preferably provided with three segments, a middle segment which lies substantially horizontally while the beam is stationary, and forward and rear segments which are inclined upward. The forward section allows the tool to follow the ground, while the orientation of the real tool enhances the breaking action of the tool.

Abstract: 1. Feeder for a casting, in particular of cast-iron, with a body (3) in the form of a hollow cylinder consisting of an exothermic heating material, which keeps the substance located in the feeder liquid until the suction of casting material through the region of the casting to be fed is terminated, in which case the volume of the feeder corresponds to the magnitude of the suction volume plus a maximum safety amount of 30% of the suction volume, characterised in that adjoining the body (3) of the feeder in the form of a hollow cylinder, on the side remote from the casting is a receiving chamber (8) which is enlarged with respect to the cavity (4) of this body (3), which chamber (8) is surrounded on all sides by an exothermic heating material, which to a large extent prevents cooling of the casting material located therein, whereas the body (3) in the form of a hollow cylinder serves for heating the casting material passing through this body during the suction operation.

Abstract: In the treatment of wastewater, the mixture of wastewater and the sludge is transported through a treatment zone, and then through a filter zone containing a bed of support particles, e.g., particles of polyurethane foam, to deposit the biomass onto the support particles. The loaded support particles are subsequently regenerated within the filter zone by means of a regenerating means in the same area as the filter zone, e.g., by strong aeration or by being compressed between press-rolls, whereby the system requires neither additional land for regeneration of the support particles nor a secondary settling tank.

Abstract: Un conteneur de stockage des composants du sang est fabriqué avec une composition de chlorure de polyvinyle plastifié qui comprend un système de stabilisation thermique sélectionné à partir du groupe constitué de sels d'acides gras saturés de C10 à C26 présents en une quantité inférieure à 1 % environ en poids de la composition. De manière surprenante, en utilisant uniquement des quantités minimes de ces acides gras de poids moléculaire élevé on obtient un produit présentant une stabilisation thermique efficace et indiqué dans le techniques de production en masse. Le résultat est que la quantité totale de stabilisateur thermique pouvant lessiver dans le plasma sanguin est considérablement réduite. Le matériau à partir duquel le conteneur est fabriqué comprend de préférence une quantité effective d'un plastifiant qui est aussi essentiellement non-extractible dans le plasma sanguin.

Abstract: A microwave sterilizer for sterilizing a connector or coupling that interconnects a first conduit from a source of liquid to be infused into a living body to a second conduit implanted in the body. The apparatus of the invention comprises a housing having first and second members forming a guided wave structure adapted to be removably closed around the coupling or connector and further including first and second clamping means. The clamping means are adapted to clamp respective conduits and are operable to isolate a charge of the liquid within the connector. A microwave source is used to generate energy which in turn is coupled to the guided wave structure to cause heating of the liquid charge to a temperature level to cause sterilization so as to destroy substantially all form of bacteria therein. After a predetermined heating sequence, the apparatus is released and the bag side clamping means is first released so as to pass the sterilized charge of liquid into the source or bag.

Abstract: NMR imaging is achieved in the presence of temporal variations in the magnetic field. The volume (10) is excited using broadband excitation (14, 15). A signal is picked up in the plane of interest, using a small coil (28), and used to determine the frequency of the subsequent plane-selecting excitation. A similar coil (21, 23) can be used to pick up the signal used to image the plane using projections all in the same direction. This latter signal is used to provide the demodulation signal (w2 - w1) to decompose the selected plane into its constituent elements. In both cases, involving the excitation and decoding signals, drifts in the magnetic field (B0) are compensated for.

Abstract: In the manufacture of packing containers of the type containing a liquid product with a certain portion of "solid" particles (e.g. soup with pieces of fruit) it is difficult to fill the packing containers (14) in such a manner that the desired proportions of liquid and solid contents are safeguarded. This is the case in particular in modern, fast working packing machines, since the filling time is short and a rapid filling, moreover, increases the risk of contents ending up in undesirable places and rendering difficult the sealing of the packing container. In accordance with the invention which relates to a method as well as to an arrangement for the manufacture of packing containers, this is solved by feeding the solid and liquid parts separately via two filling pipes (10,11), the feeding of the liquid contents being ended only after the feeding of solid particles has been ended.

Abstract: A stream of permanent gas such as nitrogen at elevated pressure is cooled to below its critical temperature by heat exchange with work-expanded working fluid. The stream 2 is then further cooled in heat exchanger 4 and successfully flashed through at least three expansion valves 6, 12 and 16. Resulting flash gas is separated from liquid gas in separators 10, 14 and 18 respectively. The flash gas is passed through the heat exchanger 4 to provide cooling for such heat exchanger. By performing at three such successive isenthalpic expansions instead of the conventional one or two expansions, greater thermodynamic efficiency can be achieved enabling more favourable conditions to be set for the work expansion of the working fluid.
