Title: Systems and methods eradicating contaminants in fluids
Inventor: WOLF LUDWIG JR
IPC: A61L2/08
Filed: 1991-12-20
Abstract: A system (10) and method for treating a fluid carrying a contaminant to which a photoactive material has been bound include a treatment device (12) that defines a flow passage (36) with a dap (28). The system and method operate to establish a flow of fluid from the inlet (38) end of the gap (28) to the outlet end (40) of the, gap (28). The system and method also channel he flow of fluid in the gap (28) in succession through one or more paths. The system and method esta-blished at least two discrete sources of ra-diation (30), in the flow path (36) at spaced, apart locations along the direc-lion of fluid flow. At least one of the ra-diation sources (30) comprises a photodi-ode. The system and method further in-clude a control far operating each dis-crete source of radiation at a selected wavelength within the prescribed range to activate the photoactive material bound to the contaminant. Upon activa-tion, the material eradicates the contami-nant. The system and method provide ex-tracorporeal treatment of fluids like blood to quickly and effectively eradicate infection agents at relatively high flow rates.

Title: Container with substantially planar side surfaces
Inventor: SOERENSEN ERLING
IPC: B29C61/00
Filed: 1991-03-04
Abstract: A container is produced from a preform which is formed by expansion in the axial and/or radial direction of a hollow blank of originally substantially amorphous material. In the production, the circumference of the preform is reduced by heating of material in the preform body, at least one material portion of the container body being displaced, by means of a mechanical forming device (30), in a direction towards the centre of the preform for forming an outer bounding surface of the container comprising material portions whose distance to the centre axis of the container is less than the distance of corresponding material portions to the centre axis (26) of the preform. An apparatus for producing the container includes the mechanical forming device which, during reforming of the preform into the container, abuts against material in the preform. The mechanical forming device includes a forming portion (33) provided with channels for thermal medium and with a forming surface (37) disposed, under energy exchange with material in the preform, to displace material shrunk by heating of the material towards the centre axis of the preform.

Title: Multiple zone batch treatment process
Inventor: MEIDL JOHN A
IPC: C02F3/10
Filed: 1992-11-04
Abstract: MULTIPLE ZONE BATCH TREATMENT PROCESS     XXXXXXXXXXXXXXXXXXXXXXXX                           ABSTRACT     A process  is described for the operation of a multiple zone batch treatment system  for  biological  or biophysical treatment of  wastewater.   The system comprises two or more batch treatment  zones with  wastewater passing sequentially through all treatment zones.  After the mix and settle batch steps occur  for all  zones, influent  wastewater flows into the first  zone and displaces clarified wastewater in a plug flow mode  through each  treatment zone  and ultimately from the last  zone.   The combining of the decant and fill steps for all or most of  the  zones  provides  for  shorter cycle times and greater capacity for the system.     XXXXXXXXXXXXXXXXXXXXXXXX

Title: High utilization supported catalytic metal containing gas-diffusion eelctrode, process for making it, and cells utilizing it
Inventor: REDDY N R K VILAMBI
IPC: H01M4/86
Filed: 1991-08-12
Abstract: Gas-diffusion electrodes (GDE's) are obtained by starting with a GDE which is fully fabricated except for electrocatalytic metal treatment and solid polymer electrolyte (s.p.e.) treatment. This untreated GDE is treated by a) impregnating an s.p.e. solution into the catalytic face until the solution penetrates part way into the cross-section of the GDE support material, but not as far as the hydrophobic, gas permeable face, b) inserting the thus-treated GDE and a counterelectrode into a plating bath containing, M+, M++, and/or M+++ ions, where M is a metal of Group VIII or I-B of the Periodic Table, and c) applying an interrupted current to the thus-treated GDE, so metal particles < 10 nm in average particle size deposit on the particulate support material of the catalytic face, but essentially only on sites that are already in contact with the previously-deposited s.p.e.

Title: Temperature controlled centrifuge
Inventor: BRIERTON MARK J
IPC: B04B15/02
Filed: 1993-04-14
Abstract: ABSTRACT    A temperature-controlled centrifuge in which a heat exchanger  is  attached  to  the  bottom  portion  of  the centrifuge bowl to remove heat from the bowl and materials within the bowl interacting therewith.  In one embodiment, a heat exchange plate having a plurality of substantially annular channels is appropriately attached to the bottom of the  centrifuge  bowl  and  has  a  surface which  is  thus substantially  coextensive  therewith.    Each  of  these channels are positioned at different radial distances from the central axis of  the heat exchange plate and each extends substantially about such axis.  An appropriate heat transfer medium may thus be circulated through each of these  channels  to  thereby  substantially  control  a temperature across the entire bottom of the bowl.  The heat transfer medium may be provided to each of the channels by a common feed inlet which also allows for the use of flow regulators where appropriate, and the heat transfer medium may also thus be removed from the channels by a common dump line.  Consequently, coaxial conduits may interact with the bottom portion of the heat exchanger for interconnection with the common feed and dump lines.     Figure 5
