Abstract: A signal amplification system comprises a bacterial multi-hybrid system, and more preferably a two-hybrid system, of at least two chimeric polypeptides containing a first chimeric polypeptide corresponding to a first fragment of an enzyme and a second chimeric polypeptide corresponding to a second fragment of an enzyme or a modulating substance capable of activating said enzyme. The first fragment is fused to a molecule of interest and the second fragment or the modulating substance is fused to a target ligand. The activity of the enzyme is restored by the in vivo interaction between the molecule of interest and the target ligand. Signal amplification is generated and, for example, triggers transcriptional activation. The signal amplification system is useful in a method of selecting a molecule of interest, which is capable of binding to target ligand, wherein the interaction between the molecule of interest and the target ligand is detected with the signal amplification system as a kit therefor. A method of screening for a substance capable of stimulating or inhibiting the interaction between a target ligand and a molecule of interest is also provided.

Abstract: A stab joint, pipe assembly, and method of forming a seal between a corrugated pipe and a bell utilize an annular gasket secured to a corrugated pipe through the use of a compression strap that applies a compressive force to the gasket to form a seal between the gasket and the outer engagement surface of the pipe. The annular gasket overlays an adjacent crest and valley on the outer engagement surface of the pipe and is formed of a compressible material having an uncompressed radial thickness that is greater than the radial distance between the inner engagement surface of the bell and a crest on the outer engagement surface of the pipe. When compressed by the compression strap, at least a portion of the annular gasket has a diameter that is greater than that of the strap such that the annular gasket forms a seal with the inner engagement of the bell when the pipe is inserted into the bell.

Patent CA-2322803-A1 (CA)
Inventor: RICHARDSON TIMOTHY M
IPC: C23C16/52
Filed: 1999-02-05
Abstract: A method and apparatus for creating three dimensional solid forms in metals, ceramics, organics or any combination thereof is made possible using a computer controlled system to create local environmental conditions that favor deposition from a material stream, precursor gas, weld process or plasma. In order to increase control and accuracy, the material can also be placed while the target area is monitored by a broadband poly-spectral imaging system, which provides dimensional, geometrical, chemical composition, stress and temperature feedback to the computer controlling the process. The local environmental conditions in the deposition area are controlled for magnetic, electric, and acoustic fields as well as for temperature, pressure, flow dynamics, and atmospheric composition. Complex materials can be "written" to match a computer's file of a three dimensional shape with virtually any material composition, surface finish, and geometrical complexity. Discrete components, such as microspheres, optical, electronic or any other components or materials that do not lend themselves to the deposition process, can be inserted and the shape written around them to make them an integral part of the final form. While the system can "write" a three dimensional shape it can also be used to "erase" some or all of a shape. The environmental conditions can also be changed so that material can be removed under computer control so that any corrections or final features can be created including such operations as final polishing or surface finishing. The digital files containing the three dimensional image, environmental and compositional data can be sent to remote locations where the data can be used to write a new three dimensional object.

Filed: 1999-06-18
Abstract: An integrated organic/inorganic complementary thin-film transistor circuit comprises a first and a second transistor which are operatively connected on a common substrate, wherein the first transistor is an inorganic thin-film transistor and the second an organic thin-film transistor. The inorganic thin-film transistor is an n-channel transistor and the organic thin-film transistor is a p-channel transistor or vice versa. Each of the transistors has a separate gate electrode and the organic active semiconductor material is in the case of a p-channel semiconductor in the organic thin-film transistor electrically isolated from the inorganic thin-film transistor. In a first method for fabricating a transistor circuit of this kind separate gate electrodes are deposited for each transistor on a common substrate, the material for the source and the drain electrode of the organic thin-film transistor are deposited on the same layer level in the thin-film structure of the organic thin-film transistor and in each case the organic active semiconductor material in an organic p-channel transistor is provided electrically isolated from the inorganic n-channel transistor, and the organic active semiconductor material in an organic n-channel transistor optionally electrically isolated from the inorganic p-channel transistor. In a more specific method for fabricating a complementary transistor circuit the inorganic active semiconductor is deposited in the form of hydrogenated amorphous silicon and an n+ doped layer of a silicon material is deposited as respectively source and drain areas in the organic transistor.  A layer of pentacene is deposited over an isolated layer which is patterned such that the pentacene which forms the active semiconductor in the organic thin-film transistor is isolated electrically from the inorganic thin-film transistor.

Inventor: FRANCIS DANIEL F
IPC: F21V29/15
Filed: 2001-07-06
Abstract: A finishing section of a recessed wall wash light fixture has a heat conducting side wall. The inner surface of the side wall has a reflective finish. A lamp is non-centrally aligned within the finishing section. The reflective sides cooperate with the off axis location of the lamp to operate as a kick reflector to kick a portion of the light emitted outward from the fixture at high angles to illuminate a nearby wall close to the ceiling line. The finishing section functions as a lamp support, heat shield and kick reflector reducing the number of parts and complexity of assembly typical of wall wash light fixtures. The finishing section is mounted substantially within a rough-in section housing. An aperture cone section, lens, hinge and bias mechanism, and rotatable collar improve performance and functionality of the fixture.
