摘要:
A bypass turbofan gas turbine engine is started by means of electric starter motor mounted directly about a downstream end or upstream of the low pressure spool of the engine. This causes air to be driven by a fan through a bypass duct around the engine casing. Closures close to substantially seal an outlet of the bypass duct, and the air is directed into a combustion chamber of the engine and through the turbines, causing the high pressure spool to pick up speed for starting.

The bayonet attachment on the cartridge for attaching a mixer or accessory to a multiple component cartridge is formed as a ring-shaped bayonet socket with two internal recesses and two diametrically opposed cutouts forming one bayonet coupling part means, whereas the bayonet attachment of the mixer or accessory comprises two bayonet lugs corresponding to the cutouts. In a preferred embodiment the lugs and cutouts are of different widths for the coded alignment of the mixer or accessory to the cartridge in one predetermined position only.

The mixer of the mixer-cartridge assembly comprises a housing, an inlet section having an individual inlet for each outlet of the cartridge and a mixer element group. The mixer inlet section comprising a separating element and the mixer element group are arranged thus, that while sealingly connecting the mixer to the cartridge, the inlets of the mixer remain aligned with the corresponding and matching outlets of the cartridge as well as with the separating element and with the dividing element of the mixer element group for optimizing the mixing of the components. For mixer attachment, the mixer housing comprises bayonet lugs cooperating with bayonet prongs on the cartridge, whereby the housing is rotated while the mixer inlet section, separating element and element group do not rotate in regard to the cartridge outlets, thus avoiding cross-contamination of the components at the cartridge/mixer interface and assuring continued separation well into the mixer up to the first dividing element.

The present invention provides a process for the adjustment of the electron acceptor strength of a transition metal oxide (TMO) to the HOMO of a semiconducting hole transport layer material (HTL material) in a device comprising an anode, a layer of said TMO deposited on said anode and a layer of said HTL material deposited on said TMO layer, comprising: depositing a solution comprising a precursor for said TMO on said anode, wherein the precursor solution has a pH selected so that the acceptor strength of the TMO for which the solution is a precursor is adjusted to the HOMO of said HTL material; drying the deposited solution to form a solid layer precursor layer; depositing a solution of said HTL material onto said solid layer precursor layer; and annealing thermally the resulting product to give the desired device having TMO at the interface between said anode and said HTL.

The device for the continuous monitoring of the correct proportioning and mixing of at least two fluids comprises a static or dynamic mixing device ending in a nozzle, wherein within the nozzle, the cross-sectional area of the stream or flow after the last mixing element of the static mixing device or at the end of the dynamic mixing device, as seen in the direction of flow, is substantially reduced compared to the cross-sectional area of the mixing part of the mixing device. This reduction is realized either by an internal volume displacing means or by reducing the diameter of the nozzle after the last mixing element of the static mixing device or at the end of the dynamic mixing device, and the nozzle being at a maximum transparency at the point of scanning. Such devices allow a more accurate monitoring since the greatest possible part of the stream of the mixed material can be more easily viewed or sensed.

A lockout safety device used in combination with a conveyor pullcord syst The device is used to tension and then lock the conveyor system's pullcord in the tensioned position which action renders the conveyor inoperative. Several embodiments are disclosed each of which is portable, simple in structure, inexpensive, compact in size, and useable anywhere along the length of the pullcord. Each functions to cam its surface against and thereby tension the pullcord which then allows it to be locked in that position. In the preferred embodiment, two sets of parallel members are pivotably joined together with each set having a pin to engage the pullcord on one side while the pivot engages it on the other side.

A rotatable mounting block with a coal cutter bit which reduces the amount of wear to the bit. The cutter bit is fixed within the bore of a bit holder and moves in unison therewith within the mounting block. Positive rotation of the holder/bit is provided by a ratchet sleeve and pawl which interact with spiral slots on the lower extending end of the bit holder. The pawl prevents rotation of the ratchet sleeve in one direction (downward) so that the cutter bit will rotate during movement into the mounting block's bore as inwardly facing sleeve teeth are cammed in the slots of the bit holder. On the upward stroke of the bit/holder within the mounting block, the ratchet sleeve is free to rotate as a strong Belleville spring--also in the mounting block--forces them upward to the original position.
