Title: Alleviation of cardiotoxic effects of anthracycline glycosides
Inventor: SINGAL PAWAN K
IPC: A61K31/10
Filed: 1995-05-31
Abstract: Anthracycline glycosides such as doxorubicin (adria-mycin) and daunorubicin have valuable anti-tumorous properties but also display cardiotoxic side effects that limit their usefulness.  It has now been discovered that the cardiotoxic side effects in a patient can be reduced or alleviated if the patient is also treated with a lipid-lowering drug having antioxidant property, for example probucol.

Title: Compressed air foam pump apparatus
Inventor: MORAND JAMES W
IPC: A62C5/02
Filed: 1993-12-23
Abstract: Fire fighting apparatus (10) for generating air compressed foam having both a water and a surfactant metering device (26, 20) for dispensing controlled and discrete quantities of both into a mixing conduit (24) where they combine into a foam solution. The foam solution is combined with air (44) prior to being injected within an air compressor device (40) where foam is generated and then is discharged therefrom. The air compressor (40) is also controlled to dispense a discrete quantity of foam therefrom in correlation with the discrete quantities dispensed from the other two metering devices (26, 20). The quantitative dispensing coordination of the air compressor (40) with the two metering devices (26, 20) make all three devices (20, 26, 40) both relational and proportional in the cooperative generation of compressed air foam, and thus ensures prompt production of constant quality foam. Various environmental operating parameters are monitored and controlled to enable prompt production of constant quality air compressed foam.

Title: Magnetic system for medical instrument
Inventor: PARKER JAMES R
IPC: G01N33/49
Filed: 1994-08-18
Abstract: An instrument (100) monitors the coagulation of coagulable fluid blood, blood fraction or a control (514) by combining (101) the coagulable fluid (514) with particles which are affected by a magnetic field so that the particles become suspended relatively freely in the fluid. A time-varying magnetic field (2 Hz) causes the particles to be reori-ented as the magnetic field varies. The reorientation changes as the fluid (514) coagulates owing to the fluid's (514's) changing viscosity. An electromagnet (140) creates the time-varying magnetic field. The electromagnet (140) includes a core (150) comprising a first leg (148), an electrically conductive coil (144) for creating a time-varying magnetic flux in the core (150), and a return (152) for the time-varying magnetic flux. The first leg (148) and the flux return (152) together comprise a generally E-shaped core (150) of ferromagnetic material. A bobbin (146) is provided on the first leg (148) and the electrically conduc-tive coil (144) is wound on the bobbin (146).

Title: Composite refractory/carbon-containing components of aluminium production cells
Inventor: SEKHAR JAINAGESH A
IPC: C25C3/08
Filed: 1993-11-12
Abstract: A component of an aluminium production cell, in particular a cathode or a cell lining of an electrolytic cell for the production of aluminium by the electrolysis of alumina in cryolite, having an aluminium-wettable refractory coating on a heat-stable baked carbon-containing body, is produced from a part-manufactured cell component which is a layered composite of two precursors. A precursor layer of the aluminium-wettable refractory coating contains at least one aluminium-wettable refractory material in particulate form, or a particulate micropyretic reaction mixture which when ignited reacts to form at least one aluminium-wettable refractory material, or a mixture thereof, and non-carbon fillers and binders. A non-baked or part-baked precursor of the heat-stable carbon-containing body comprises particulate carbon compacted with a heat-convertible binder which when subjected to heat treatment binds the particulate carbon into the heat-stable carbon-containing body of the fully-manufactured cell component. This layered composite is convertible to the fully-manufactured cell component by heat treatment to form the aluminium-wettable refractory coating and simultaneously bind and heat-stabilize the carbon-containing body.

Title: Atm architecture and switching element
Inventor: HOLDEN BRIAN D
IPC: H04L12/56
Filed: 1995-04-13
Abstract: An ATM switching system architecture of a switch fabric type (20) is built of a plurality of ATM switch element circuits (40) and routing table circuits (30) for each physical connection to/from the switch fabric (20). A shared pool of memory (100) is employed to eliminate the need to provide memory at every crosspoint. Each routing table (30) maintains a marked interrupt linked list for storing information about which ones of its virtual channels are experiencing congestion. This linked list is available to a processor in an external workstation to alert the processor when a congestion condition exists in one of the virtual channels. The switch element circuit (40) typically has up to eight 4-bit-wide nibble inputs (10-17) and eight 4-bit-wide nibble outputs (O0-07) and is capable of connecting cells received at any of its inputs (10-17) to any of its outputs (00-07), based on the information in a routing tag uniquely associated with each cell.
