Title: Highly active cationic ruthenium and osmium complexes for olefin metathesis reactions
Inventor: DIXNEUF PIERRE
IPC: C07B61/00
Filed: 1998-11-17
Abstract: The present invention describes the use of cationic vinylidene, allenylidene and higher cumulenylidene complexes of ruthenium or osmium as catalysts or catalyst precursors for olefin metathesis reactions of all types, as well as to new cationic allenylidene complexes of ruthenium and osmium which can be used as metathesis catalysts with preferred embodiment. These catalysts or catalyst precursors are easy to prepare from well accessible, stable and essentially non toxic starting materials, can be isolated and stored, they exhibit a high catalytic activity, a good compatibility with functional groups, solvents, water and additives, and they need not be activated by any additive. Olefins of all types can be used as the substrates in the present invention in ring closing metathesis (RCM) of acyclic dienes and polyenes, the metathesis of enynes and dienynes, the ring opening metathesis polymerization (ROMP) of cyclic olefins, the acyclic diene metathesis polymerization (ADMET) of acyclic dienes or polyenes, the depolymerization of olefinic polymers, and the cross metathesis of two or more olefins. The present invention also applies to combinations of these types of metathetic reactions and domino processes thereof.

Title: Power rate adjustment mechanism for a seeding implement
Inventor: STANFILL RALPH EVERETTE
IPC: A01C7/10
Filed: 2000-07-20
Abstract: A power seeding rate adjustment mechanism for a seeding implement has a threaded lead screw that is rotated by an electric motor. A nut threaded onto the lead screw is fixed to the shifter lever such that when the lead screw is rotated, the nut translates along the length of the lead screw to pivot a shifter lever. The shifter lever is in turn coupled to a seed meter drive shaft to move the shaft transversely, thereby moving fluted feed wheels in or out of the seed cups. A switch carried by the operator in the pulling tractor actuates the motor. The adjustment mechanism enables the operator to make adjustments on-the-go without stopping or leaving the tractor. The motor can be disengaged from the lead screw and the screw turned by a hand crank for manual adjustment in the event of a power failure to the motor.

Abstract: A method of producing a resilient decorative construction material from waste products such as slag granulate or waste glass granulate is taught. A layer of material (10) comprising glass granulate, slag granulate, or sand, or mixtures thereof, is placed in a heat-resistant mold (12). The mold (12) has a top (22), sides (24) and a bottom (20) which is preferably coated on the inner mold surface (18) with a fluid suspension of kaolin (13). The layer is thermally treated, and is initially heated so that a temperature gradient is established throughout the layer, with the first surface (14) having a first temperature no greater than the softening point, and the second surface (16) having a second temperature less than the first temperature. Then further heating is conducted to a temperature sufficient to sinter the layer, and also to reverse the temperature gradient throughout the layer, so that the first surface (14) has a lower temperature than the second surface (16). The layer is maintained at temperature and then cooled annealed to produce the final product.

IPC: E04C3/02
Filed: 2000-11-01
Abstract: A ribbed concrete structural form using a series of lightweight extruded plastic structural formwork members for use in constructing ribbed concrete floor, ceiling, and roof slabs.      The members comprise an elongate tubular conduit essentially rectilinear in cross-section, and formed by a pair of substantially parallel side walls, a floor, and a top.      There is substantially centrally located a longitudinal interior horizontal web substantially parallel to the top and floor thereof, and extending between the parallel walls to form upper and lower passageways through, the interior of the conduit. There is a vertical web parallel to the side walls, and extending from the interior horizontal web to the floor substantially centrally thereof to form a group of longitudinal spaces. There is also a first and second sloped web extending downwardly and outwardly in opposite directions at an angle acute to the intersection of the horizontal web and the vertical web with opposite ends of the sloped webs joining at the intersection of each lateral wall and the floor.      The floor extends beyond the parallel side walls on each side to form substantially flat bottomed wing-like projections. The outer longitudinal edges of each wing include longitudinal mating connecting means arranged to seat in a sealing relationship when a plurality of the members are interconnected to form a slab. The sealing relationship is sufficiently impermeable to prevent the flow of constituents of the concrete being cast above them.     There are a series of seats or chairs arranged to be placed over the connecting structure of an adjacent pair of wing edges in the sealing relationship and to support the reinforcing bars above the wings substantially parallel to support the connecting means.

Inventor: ULLOM JOEL NATHAN
IPC: H01L39/22
Filed: 1999-06-16
Abstract: A superconductive tunnel junction device in which quasiparticles in a superconductive region (S1), relax into a normal metal trap (N1) releasing their potential energy in electron-electron interactions to increase the number of excited charge carriers in the trap. The excited charge carriers tunnel through an insulating tunnel junction barrier (I2) into a second superconductive region (S2). The quasiparticles in the first superconductive region are formed either by absorption of energetic particles/radiation or by injection by charge earners tunnelling in from a base region which can be of normal metal (N0) or superconductor (or both) or semiconductor. The current from the trap to the second superconductor is higher than that out of the base region thus providing current amplification. The device can thus form a three terminal transistor-like device. It can be used as or in particle/radiation detectors, as an analogue signal amplifier, microrefrigerator or digital switch.

Abstract: The subject invention involves a test procedure for screening for potential cellular toxicity of a test compound comprising the following steps: a) making liposomes from one or a mixture of lipids to simulate a cell membrane composition of interest, the liposomes being made in an aqueous medium having a pH which is thereby the inside pH of the liposomes; b) incorporating the liposomes in an aqueous test medium having a pH at least about 0.5 pH units above the inside pH of the liposomes, whereby a pH gradient exists between the test medium and the insides of the liposomes; c) incorporating a fluorescent dye in the test medium, the dye having a tendency to penetrate into the liposomes due to the pH gradient, the dye being pH sensitive such that the fluorescence of the dye is quenched inside the liposomes; d) incorporating the test compound in the test medium; whereby, if the test compound disrupts the structure of the liposomes or otherwise causes dissipation of the pH gradient between the test medium and the insides of the liposomes, the fluorescence of the dye is not quenched; e) determining the fluorescence of the test medium and comparing the determination with those of controls.

IPC: H04W8/20
Filed: 1999-05-21
Abstract: A method for reducing communications with, and signalling to and from, an HLR  (204) is disclosed for local or MSC-originated calls (118). When a subscriber registers (114) with the HLR (204), the complete profile for that subscriber is transferred (116) to the VLR (207) associated with the MSC (206) (or MSC/WOS) involved. When a call (118) to the subscriber is originated in the MSC (206), the VLR (207) associated with that MSC (206) is checked (102) to determine if the subscriber's location information is already maintained in the VLR (207). If so, the MSC (206) can page (122) and route the call to the subscriber's mobile phone via (222) the base station transmitter (210, 212, 214) associated with the VLR (207). As such, for such local MSC-originated calls (118), there is no need to interrogate the HLR (204) for subscriber information, thus reducing signalling to and from the HLR (204).
