316,327. Crary, J. H. March 24, 1928. Two-stroke-cycle engines; cylinders, ports of.-At the end of the power stroke of the piston, air pre-compressed in the crank case enters by the port 7 and assists to drive out the exhaust through the terminal port 8. During the instroke an auxiliary exhaust outlet 15 is opened by the valve 16, its time of opening being adjustable, automatically or otherwise. Mixture which has been compressed in the annular pump space 2 is delivered to the cylinder past the valve 13 after the valve 16 is closed.

[Classes 7 (ii) and 7 (vi).] At the end of the expansion stroke air compressed in the crank case is admitted through the terminal port 9 to scavenge the cylinder ; on the up-stroke a supplementary exhaust port 19 is opened by the valve 18, the time of opening and consequent rejection of part of the scavenge air being variable. During the expansion stroke a variable amount of mixture is drawn into the annular pump chamber 3, this charge being delivered to the combustion space past the valve 16. The mixture admission valve 26 for the pump chamber and the exhaust valve 18 are worked off cams 32, 30 axially slidable by the handle 42 through sleeves 38, 39 and forks 40, 41 which engage collars on the cams. In a modification the mixture admission valve 52, Fig. 4, rotates and has a through way 58 of variable width ; the valve is axially slidable in its casing to vary the quantity of indrawn mixture. Specification 316,327, [Class 7 (ii), Internal-combustion engines, Arrangement &c. of], is referred to.

277,544. Crary, J. H. Jan. 31, 1927. Two-stroke-cycle engines; cylinders, internal passages of. - The combustion chamber is formed within a reciprocating cylinder 2 working m a fixed cylinder 1, the piston reciprocating in the cylinder 2; air is compressed by the upper side of the reciprocating cylinder and a rich mixture in the crank case. The reciprocating cylinder has ports 17, 10 and 28 and the piston ports 18, 11 and 27 to register with a scavenging air admission port 16, a rich mixture port 9 and an exhaust port 26 in the fixed cylinder; the exhaust port and air admission port are closed before the mixture ports coincide to admit the mixture from the crank case. This may be supplied to the crank case under pressure and is delivered through a pipe 8 with a non-return valve 20. The ports in the piston are formed in a ring extension 12 on the piston top, a deflector 19 for the air being also provided. The sparking plug 21 carries contacts 22 permanently in engagement with fixed contacts 23.
Abstract:
A method of sensing a process utilizing a sensing apparatus consisting of more than one diode laser having select lasing frequencies, a multiplexer optically coupled to the outputs of the diode lasers with the multiplexer being further optically coupled to a pitch side optical fiber. Multiplexed laser light is transmitted through the pitch side optical fiber to a pitch optic operatively associated with a process chamber which may be a combustion chamber or the boiler of a coal or gas fired power plant. The pitch optic is oriented to project multiplexed laser output through the process chamber. Also operatively oriented with the process chamber is a catch optic in optical communication with the pitch optic to receive the multiplexed laser output projected through the process chamber. The catch optic is optically coupled to an optical fiber which transmits the multiplexed laser output to a demultiplexer. The demultiplexer demultiplexes the laser light and optically couples the select lasing frequencies of light to a detector with the detector being sensitive to one of the select lasing frequencies.

Abstract:
A diode laser spectroscopy gas sensing apparatus having a diode laser with a select lasing frequency, a pitch optic coupled to the diode laser with the pitch optic being operatively associated with a process chamber and oriented to project laser light along a projection beam through the process chamber. This embodiment additionally includes a catch optic in optical communication with the pitch optic to receive the laser light projected through the process chamber and an optical fiber optically coupled to the catch optic. In addition, the catch optic is operatively associated with a catch side alignment mechanism which provides for the alignment of the catch optic with respect to the projection beam to increase a quantity of laser light received by the catch optic from the pitch optic and coupled to the optical fiber and a detector sensitive to the select lasing frequency optically coupled to the optical fiber. The catch side alignment mechanism may consist of means to tilt the catch optic along a first axis and a second axis orthogonal to the first axis with both the first and second axes being approximately orthogonal to the projection beam.
Abstract:
A pitch side optical system for use in diode laser spectroscopy consisting of more than one diode laser having select lasing frequencies with each diode laser being coupled to an end of a distinct input optical fiber. The pitch side optical system further consists of a multiplexer optically coupled to the other end of less than all of the input optical fibers with the multiplexer outputting multiplexed laser light to a pitch side optical fiber. The pitch side optical system further consists of a coupler optically coupled to the far end of the pitch side optical fiber and the far end of an unmultiplexed input optical fiber with the coupler combining the multiplexed laser light and the unmultiplexed laser light and outputting the combined light to a transmission optical fiber. Typically, the coupler is located near the combustion process. The pitch side optical system further consists of a pitch optic coupled to the transmission optical fiber. Typically, all optical fibers used in the pitch side optical system are single mode optical fibers.
Abstract:
A method for setting file associations during a factory installation process which includes determining an application that is installed onto an information handling system, setting a file association default that sets file association policies within a file association file, accessing the file association file to determine an appropriate file association, and associating files with the application based upon the file association policies is disclosed.
