Title: Product/process/application for improving carbon adsorptive capacity by oxygen addition in aqueous systems
Inventor: SUIDAN MAKRAM T
IPC: C02F1/28
Filed: 1990-10-12
Abstract: ABSTRACT           Activated  carbon adsorbents have long been used for  the  removal  of  impurities,  including  solubilized organic  compounds,  from  aqueous  systems.   The present invention relates to the  timely  infusion  of  oxygen  in carbon  adsorption  beds  in  a  manner that significantly increases the adsorptive capacity  of  the  carbons  used, thereby  lengthening the useful (pre-breakthrough) life of the carbons.  Generally, oxygen is added  to  the  aqueous system before or while the aqueous feed passes through the carbon  adsorption  bed.   As  a  result,  the  adsorption process  is  more  rapidly  and  effectively  carried out, resulting in lower costs,  less  down  (bed  regeneration) time  and more efficient operation than is otherwise found in prior art aqueous adsorption systems.   The  adsorption apparatus/process/method  of  preparation  of  the present invention has been found to be effective  for  removing  a variety  of  organic compounds from aqueous streams in the absence of biological activity.  The  formulation  of  the carbons  used,  the  form,  amount  and method of infusing oxygen into the aqueous feed  stream, as  well  as  other factors,    can    be   varied   to   adjust   performance characteristics so as to  meet  industrial,  research  and other performance criteria, to achieve enhanced removal of specific organic compounds, to extended the  useful  (pre-breakthrough)  life  of  carbon beds, as well as to obtain other advantages useful in a variety of applications.  The effect  of  infusing  oxygen  into  the aqueous stream can increase the adsorption bed life by as  much  as  200%  in some cases, depending on the organic compounds present and the makeup of the aqueous feed.

Title: Forming tool for forming peg holes in an anode
Inventor: BISON GIOVANNI
IPC: B30B15/02
Filed: 1990-12-05
Abstract: ABSTRACT OF THE DISCLOSURE    In a forming tool, used in the production of an anode before the firing, for forming peg holes, which forming tool has a cap plate to which at least one retaining pivot, with one end, is attached in such a way as to be fixed in terms of rotation, on which retaining pivot an essentially cylindrical forming body is rotatably mounted, on whose outer wall projections having the same slope relative to the axis of the forming body are provided, the respective angular position of the projections, after removal of the forming tool, is indeterminate inasmuchas the forming body can rotate further after release from the anode, and consequently the projections during production of the next unfired anode, can be located in a different angular position relative to the wall of the peg hole of the anode produced beforehand, with the result that automatic cleaning of the grooves formed out in the anode by the projections is made more difficult after the firing of the anode.  A forming tool having a stop, which is fixed to the cap plate and limits the rotation of the forming body in one direction and an elastic means which on the one side is connected so as to be fixed to the cap plate and on the other side is connected to the forming body and preloads the latter against the stop ensures that its projections always form the grooves in the wall of the peg hole in the same angular position relative to the finished anode, as a result of which cleaning of the peg hole by an automatic cleaning machine is made possible.

IPC: B65G51/04
Filed: 1990-12-17
Abstract: DEDICATED PIPELINE CONVEYOR FOR BULK MATERIALS                Abstract A pipeline conveyor is proposed where there are used 2 pipelines and monorail loops at the end.The containers move at high speed along the tubes and bumper to bumper at the ends where they  ac-tually block the pipelines.At the input of each pipeline there is a controlling positive chain  which is controlling the relea-se of the containers inside of each pipeline.Only one propulsion station is used ,placed at the input end of  one of the pipelines. This propulsion station is  pumping air into the pipeline ,air which is moving the containers and  then at the end of the pipeline the air is brought via a manifold in the second pipeline.At the ends the containers are pneumatically braked by thepresence of the bumper to bumper containers on the monorail and in the input and output ends of the pipelines.A certain over pressure keep the containers in motion on the monorail and in a positive/desmo-dromic relation/attitude with the positive chains.Only one propul-sion station is used,only one  manifold to bring the air in the system from the blower,the chains are used mainly to brake check the frequency and  the release in the pipeline(not for moving on the monorail).The dead end effect is performed against a continuous string of bumper to bumper containers-part of them  on the monorail and part of them in the tubes-restricted by the chain
