Title: Sewage sludge treatment with gas injection
Inventor: LONG CHARLES A JR
IPC: C02F3/26
Filed: 1990-12-21
Granted: 1999-03-23
Abstract: This invention relates to a sewage sludge treatment system resulting in an oxygenated and/or ozonated treated sludge containing substantially no pathogens.  The system includes apparatus (10) and a process for mascerating raw sludge, adjusting the pH to about 2.5 to about 3, adjusting the solids content to about 2.5% to about 4%, adjusting the temperature, if necessary, to about 20°C to about 40°C, mixing an oxygen-rich gas, such as oxygen and/or ozone with the sludge as the sludge is mixed or recirculated through a hyperbaric vessel (12) and simultaneously injecting the oxygen-rich gas into a combination gas and sludge mixing and dispersing assembly (30) in an upper portion (16) of the hyperbaric vessel (12).  Such injection causes mixing of the gas and sludge and dispersement of such mixture in a plurality of streams (76) to atomize and oxygenate the sludge.

Granted: 1999-07-06
Abstract: A connector for joining multi-conductor cables comprising first and second mating connector elements which are fixed to first and second multi-conductor cables. The first connector element holds bared sections of the conductors of the first cable in a spaced apart relationship and defines upstanding pillars over which the conductors are folded. The second connector element holds bared sections of the conductors of the second cable in a spaced apart relationship and defines apertures adjacent to the conductors which are shaped to receive the upstanding pillars, so that respective conductors of the first and second cables are urged into electrical engagement with one another when the first and second connector elements are mated. The frictional contact between the conductors ensures a self-cleaning action.

Abstract: The invention relates to a process and a device for determining the area coverage of a printing original, particularly of a printing forme of a printing press, preferably of an offset printing press, with the local diffuse reflection of a measured measuring field being determined by optical scanning of the original and the original having a location-dependent inhomogeneity, said inhomogeneity being independent of the area coverage and influencing the measuring result of the scanning.  In order to reduce measuring errors, it is provided that the printing areas have a different colour (colour difference) as compared with the non-printing areas of the original, that at least two diffuse-reflection values are determined from each measuring field (12), said diffuse-reflection values differing spectrally from one another according to the colour difference, and in that the two diffuse-reflection values are evaluated in order to separate a component of the measuring result that is influenced by the area coverage (fD) and a component of the measuring result that is influenced by the inhomogeneity (?).

Granted: 1999-12-21
Abstract: In a process of withdrawing castings while vertically oscillating a mold formed with long side walls and short side walls in vertical continuous casting, the long side walls are separated from the castings by operating a hydraulic cylinder 4 in the time zones for which the castings are applied with a large frictional force. On the contrary, the separated long side walls are made close to the castings in the other time zones for which the castings are not applied with the large frictional force. By repeating the separation and approaching of the long side walls, it is possible to obtain the castings reduced in the depths of oscillation marks and suppressed in segregations at oscillation mark trough portions.

Abstract: A void filling device is collapsible into a flattened state and expandable into an erect state and is interposed between spaced cargo when in the erect state to inhibit movement of the cargo during transit.  The void filling device includes a pair of side panels, a first and a second base panel and a foldable beam structure.   Each of the side panels has longitudinally extending first and second side edges and includes side panel portions constructed to fold about a longitudinal axis between a folded state, when collapsed, and an unfolded state, when erect.  The first base panel is hingedly secured to the first side  edges  of  the  side  panels  to  extend  transversely therebetween.  A second base panel is hingedly secured to the second side edges of the side panels to extend transversely therebetween.  The first and second base panels move towards one another when the side panel portions are folded into the folded state and move away from one another when the side panels are unfolded into the unfolded state. The foldable beam structure is  located in the interior between the side panels and is oriented transversely thereto.  The beam structure is hingedly connected  to  the  first  and  second  base  panels  to  extend therebetween and includes first and second beam panels foldable with respect to one another about a transverse axis so that, as the  first and second panels move toward and away from one another, the second beam panels fold to allow the void-filling device to collapse and expand.
