摘要:
The use is provided of a composition as a feed additive which comprises one or more endoglucanases, and 0-20% by weight, based upon the content of cellulase proteins in the composition, of a cellobiohydrolase. The endoglycanases may be one or more of EGI, EGII, EGIII and any functionally active derivative of any thereof. Such endoglucanases may be obtained from a genetically modified strain of the fungus Trichoderma. Also provided is an enzyme-based feed additive which comprises EGI and/or EGII which lack the cellulose binding domain, and 0-20% by weight, based upon the content of cellulase proteins in the additive, of a cellobiohydrolase. A further enzyme-based feed additive is provided which comprises a cereal-based carrier, one or more endoglucanases, and 0-20% by weight, based upon the content of cellulase proteins in the additive, of a cellobiohydrolase.

A piston 10, a spring operatively coupled to a piston, the spring being inside 21 or outside 41 the piston, and if the spring is inside the piston, the diameter of the spring is equal to 0.7 to 0.9, and if it is outside of the piston it is an external coil spring which is outside the cylinder which contains the piston and is able to provide a force of thousands of pounds per inch, and furthermore so that at light load the compression ratio (CR) is greater than 13 to 1 designated as CR0, at medium load has a compression ratio less then CR0 but greater than CReff, and at wide open throttle (WOT) has a CR equal to Creff, the CR is less than CR0 as would occur at medium or higher load which would lead to a flexing of the spring, and the cycle on the compression stroke is known as the HCX cycle where the pressure goes between Ppre and less than or equal to Pf.

摘要:
A pipe nipple has a bore therethrough, with an entrance chamber at one end of the bore having a larger diameter adjacent a drive configuration of narrower diameter for receiving a tool therein to rotate the nipple about its longitudinal axis. The exterior of the nipple has a surface formation as a stop against which a hose can be inserted over the nipple, and a threaded length for attaching the nipple to another device.

A methodology is described by which a processing chamber used to deposit plasma-enhanced Ti-CVD films may be conditioned and passivated efficiently after either a wet cleaning or in-situ chemical cleaning, or after each successive deposition sequence. The technique allows a CVD process, such as, for example, a Ti-PECVD process, to recover film properties, such as resistivity, uniformity, and deposition rate, in a minimum time and following a minimum number of conditioning wafers, thereby improving the productivity of the system. The technique also maintains the stability of the system during continuous operation. This allows for the processing of thousands of wafers between in-situ cleaning of the chamber. Immediately following chamber cleaning and before performing the Ti-CVD process on wafers, the methodology includes forming a plasma with reactive gas to heat reactor components, then adding the coating material containing reactant to deposit the coating material onto the reactor components, then introducing an oxidizing or reducing gas into the chamber to stabilize the coating on the reactor parts, followed by resumption of the wafer coating process. During continuous operation in the Ti-CVD of wafers, the methodology includes introducing a mixture of Ar and H2 gases forming a plasma to heat reactor components where necessary, then introducing and chemically reducing TiCl4 to deposit Ti on the heated reactor components, then introducing oxidizing or reducing gas into the chamber for a period of time necessary to stabilize the Ti film. Preferably, N2 and NH3 are introduced and wafer passivation and reactor stabilization are performed simultaneously. Stabilization of the reactor only, and in some cases also the wafer, may use NH3, H2O, O2 or other gases.

The invention includes novel fusion nucleic acids encoding fusion polypeptides which when expressed in a filamentous fungus result in the expression of fusion polypeptides. The fusion nucleic acids comprise four nucleic acids which encode a fusion polypeptide comprising first, second, third and fourth amino acid sequences. The first nucleic acid encodes a signal polypeptide functional as a secretory sequence in a first filamentous fungus. The second nucleic acid encodes a secreted polypeptide or functional portion thereof which is normally secreted from the same filamentous fungus or a second filamentous fungus. The third nucleic acid encodes a cleavable linker while the fourth nucleic acid comprises at least two nucleic acids encoding desired polypeptides.
