IPC: H01G13/00

Abstract: Terminating the ends of passive electronic components entails applying a laser-ablative coating (70) to each of the opposed major surfaces (14 and 16; 36 and 38) of a substrate (10 and 34). A UV laser beam having a spot size and an energy distribution sufficient to remove the laser-ablative coating from multiple selected regions of the major surfaces is directed for incidence on the substrate. Relative motion between the UV laser beam and substrate effects removal of sufficient amounts of laser-ablative coating to expose the multiple selected regions of the opposed major surfaces. The substrate is then broken into multiple rowbars (48 and 50), each of which includes side margins (60 and 62) along which are positioned different spatially aligned pairs of the selected regions of the opposed major surfaces. An electrically conductive material is applied to the side margins to form electrically conductive interconnects (56 and 58) between each spatially aligned pair of the selected regions.

Title: Silicone defoamer to better control hydrocarbon foam and reduce silicon content of liquid hydrocarbon products
Inventor: KREMER LAWRENCE N
IPC: C10G9/00
Filed: 2004-11-22
Abstract: It has been discovered that crosslinked polydimethylsiloxane (PDMS) resins are useful defoamers and antifoamers for hydrocarbon-containing liquids, such as delayed coker feedstocks and feedstocks to preflash and atmospheric towers.  These PDMS resins are crosslinked with either alkyl polysilicate or siloxane.  The crosslinked PDMS resins may be used alone or together with linear PDMS, and are typically blended with a carrier such as kerosene for easier handling.  Importantly, the use of crosslinked branched PDMS resins permit less total amount of polysiloxanes to be used, which reduces the silicon carryover in coker products and reduces poisoning of downstream catalysts.

IPC: F42D1/02
Filed: 2004-10-13
Abstract: A method of blasting plural layers of material (3 8, 40, 42, 44) in a blastfield (16) that reduces the amount of mechanical excavation required to expose a lower layer of material. The method includes using rows of equally spaced blastholes (18, 20, 22, 24) that pass through all of the layers and additional intermediate rows of blastholes (26, 28) that pass down only through top layer (40). Each blasthole is capped with stemming material and includes one or more decks of explosives material (46) and detonators (48), with air decks or inert stemming (45) separating adjacent explosives decks (46). The detonators in layer (40) are detonated first in order from row (18 ) rearwards to throw a substantial amount of the blast material from layer (40 ) forwardly of free face (12) onto floor (34). In the same blasting cycle and within seconds of the throw blast, explosives material in layers (42, 44) is detonated in a stand-up blast in which material in layers (38, 42, 44) is broken up but otherwise minimally displaced or thrown forwardly. Layers (38, 44) may be coal seams which are separated by interburden layer (42) and covered by overburden layer (40).

Title: Epichlorohydrin based polymers containing primary amino groups as additives in papermaking
Inventor: PIKULIK IVAN I
IPC: C08K3/00
Filed: 2005-02-23
Abstract: Processes for preparing water-soluble papermaking polymer additives having a multitude of free amino groups effective to form cationically charged complexes with components of a pulp suspension are described, comprising:  reacting ammonia and epichlorohydrin (ECH) with ammonia in excess to yield a starburst polymer with a molecular weight of 3000-106; reacting ECH and ammonia to produce tris(3-chloro-2-hydroxypropylamine) and reacting this with a diamine to yield a water-soluble branched polymer with a molecular weight of 3000-106; reacting polyepichlorohydrin with a variety of amines, a polyol or ammonia to yield linear polymers, cross-linked polymers and polyamines. The additives are used as agents for improving retention, drainage, product strength and paper machine operation in paper manufacture. Under neutral or acidic conditions these primary amino groups become cationic, which assures good adsorption of the polymer onto anionic fibres and fines used for production of paper or paperboard. By adsorbing on several fibres or fines, the polymer can increase the retention of fines and fillers. Primary amino groups of these polymers can also form chemical bonds with carbonyl groups of cellulose, lignin and hemicellulose, which are especially abundant in the fibres and fines of mechanical pulps. The cross-linking of fibres and fines by chemical bonds can increase the initial strength of wet web and the strength of rewetted paper.

Title: Belt installation tool
Inventor: HODJAT YAHYA
IPC: F16H7/24
Filed: 2005-01-13
Abstract: A belt installation tool for installing a belt without rotating the pulley or the tool about a pulley axis of rotation. The tool comprises a ramp that engages a pulley flange. The ramp comprises a connecting member for connecting the ramp to the flange. After the ramp is connected to a pulley flange a belt is loosely engaged with the ramp. A first lever arm connected to the ramp is used to pry the ramp and belt outward by pivoting about the first connecting member until a second connecting member is engaged with the pulley flange. The ramp further comprises a member for laterally urging the belt. Once the ramp is fixed on the pulley flange a second lever arm, connected at a pivot point, urges the belt laterally onto the pulley. The second lever arm is moveable in a direction normal to the movement of the first lever arm, thereby laterally urging the belt onto a pulley.
