The novel blend compositions provide materials with improved processing/property attributes over the unmodified polymers comprising the blends. The blend compositions can exhibit a unique balance of properties including enhanced modulus and barrier properties, improved tensile strength, radio frequency (rf) sealability, solvent bondability, thermal stability and heat resistance depending upon the selection of the individual blend components and their composition ratios. Additionally, the location and the breadth of the glass transition can be controlled by varying the blend compositions and plasticizer level. Surprisingly blends including a plasticizer show a single phase material from glass transition temperature data analysis.

Abstract: A damper for a weighing device including a cavity 4 in which a plate 12 can move, which plate is designed for being connected to a weight measuring device 2.  The cavity 4 is closed tightly by a flexible membrane 14 and is partly filled with an oil, while leaving a volume of air or of a gas between the top 14a of the oil and the membrane 14, the plate 12 being totally immersed in the oil. The lower surface of the plate 12 and the bottom of the cavity 4 have shapes which are not planar and which are not parallel to each other, thus preventing the formation of a thin film of oil between them. The peripheral surface of the plate 12 and of the peripheral wall of the cavity 4 define therebetween a first constriction 15 of which the transverse section is constant whatever the position of the plate 12 in the cavity 4. The peripheral area 5 of the bottom of the cavity 4 and the peripheral area 12b of the lower surface of the plate 12 facing the bottom of the cavity 4, define together a second constriction 16 of which the transverse section varies depending on the position of the plate 12 inside the cavity 4.

IPC: B01J37/34
Filed: 2000-07-06
Abstract: A conductive sinter obtained from a mixture of titanium oxide particles and 2.5% by weight niobium oxide particles is used as a target in direct current sputtering to form a photocatalytically active film mainly comprising titanium oxide on a glass substrate. The target has a surface resistance of 500 .OMEGA./~ or lower and the sputtering is conducted while heating the substrate at 230.degree.C. The photocatalytically active film is based on an amorphous matrix. This process is free from problems of a conventional process in which a photocatalytically active titanium oxide film is deposited by reactive sputtering using titanium metal as a target. The problems are that the substrate needs to be heated to 350.degree.C or higher and that the deposited film does not have high photocatalytic activity.

Patent CA-2331984-A1 (CA)
Title: Reactivation of partially utilized sorbent
Inventor: MAHULI SUHAS K
IPC: B01J20/04
Filed: 1999-05-06
Abstract: A novel process has been developed for reactivation of partially utilized calcium-based sorbents for increased SO2 removal and sorbent utilization from coal-fired boilers/combustors. Spent sorbent and combustor ash samples are treated under specific conditions to modify their internal structure and expose the under utilized calcium for further SO2 capture. The reactivated sorbent shows significant improvement in utilization, increasing from less than 45 % to nearly 100 % utilization. Application of novel reactivation process to ash samples obtained from a circulating fluidized bed combustor also show marked improvement in utilization of available calcium, nearly doubling the amount of sulfur captured. The reactivation process involves carbonation of the unsulfated calcium. Better redistribution and exposure of the available calcium by the carbonation reactivation process, as compared to reactivation via hydration, is proposed as the main factor in increasing the sorbent utilization. The increased ultimate sorbent utilization obtained by this reactivation process could significantly improve the sorbent-based flue gas desulfurization technology.

Inventor: ATTARIAN FARSHID
IPC: H01F41/02
Filed: 2000-05-12
Abstract: In an exemplary embodiment, the apparatus includes a first station, a second station, and a third station. At the first station, raw magnetic material strip (24) is de-reeled from a stock reel (42) and a predetermined amount of the raw magnetic material strip is fed and measured as the magnetic material strip is transported to a winding mechanism (60). In the winding mechanism, the magnetic material strip is continuously wound in and through an opening formed in a bobbin (12, 14) to form a wound transformer core. Preferably, a pair of bobbins are used and the magnetic material strip is continuously wound through openings formed in each of the bobbins. After winding the predetermined amount of magnetic material strip through the bobbins, the magnetic material strip is cut at a predetermined measured location to produce a trailing edge (26) of material. At the second station (34), the trailing edge is secured to the underlying coils by a suitable process, e.g., plasma welding the trailing edge to the underlying coils. At the third station (36), the wound core of magnetic material is coined into a desired shape, such as a generally rectangular shape to form a wound electrical transformer.
