A configuration for a cryo-catheter which optimizes both the catheter's outer diameter and the size of the catheter's internal refrigerant flow path is described. Specifically, the inner dimensions of the cryo-catheter are configured to accommodate a pre-selected flow of refrigerant into the catheter's distal tip, and a return flow of refrigerant from the distal tip. The return flow is established in the void spaces between a refrigerant supply line and the inner wall of the catheter body. The available void space varies along the catheter length and depends on the presence/absence of various catheter accessories (i.e. pull wires, pressure tubes, etc.) which typically only extend through a portion of the catheter length. The disclosed configuration ensures that the cryo-catheter does not operate in a refrigerant limited condition, maintains the refrigerant as a liquid in the supply tube, and maintains the return line pressure at about 1 atmosphere.

A stator coil, being a rectangular coil, is wound on a salient pole, striding across a plurality of slots, while being inserted sequentially through the inlet of a predetermined slot of the stator core. The stator coil comprises two slot inserts and to be inserted into the slot; two coil ends and located outside the end of the slot; and four twist sections arranged between the slot inserts and coil ends, processed by twisting. In the twist sections, twisting is applied to ensure that the surface of the rectangular coil in the second coil end will be opposite to the surface of the rectangular coil in the first coil end. The start of winding of the rectangular coil and the end of winding of the same coil are located on the same surface. Thereby, a rotating electrical machine with the large internal dimensions without increasing the external dimensions can be permitted.

This motor and gearing system can be effectively installed in an existing aircraft wheel without changes to other components to produce a drive wheel with the torque and power required to move the aircraft independently on the ground.

An apparatus which inhibits the theft of equipment such as personal computers is disclosed. The equipment must have an external wall provided with a specially designed, approximately rectangular slot having preselected dimensions. An attachment mechanism includes a housing for a spindle having a first portion rotatable within the housing, a shaft extending outwardly from the housing, and a crossmember at the end of the shaft having peripheral dimensions closely conforming to the internal dimensions of the slot. An abutment mechanism also emanates from the housing, and is located on opposite sides of the shaft intermediate the housing and the crossmember.

A method of producing a stream of aqueous chlorine dioxide sterilizing fluid suitable for use in sterilizing medical and dental equipment or for wound irrigation or skin asepsis is described. Steps are:

• • pumping fluid portions of a first reagent and a second reagent into the proximal end of an elongate reaction chamber (24) to form a reaction mixture, the reagents being selected to react together to form aqueous chlorine dioxide;
  • providing a stream of water around or adjacent to the distal end of the reaction chamber (24); continuing to pump fluid portions of said reagents so as to cause the reagent mixture to travel through the reaction chamber and then into the stream of water to form a stream of aqueous chlorine dioxide sterilizing fluid;

The semiconductor laser has a resonance cavity composed of a gain chip, a Mach-Zehnder wide tuning port, and a wavelength-selective mirror component formed either as a ring resonator or a reflective Fabry-Perot etalon. Optical signals generated by the gain chip propagate through the wide tuning port and into the wavelength-selective mirror component and are then reflected back to the gain chip. The wavelength-selective mirror component is configured to reflect only those optical signals having wavelengths within a set of sharp peaks so that the laser cavity resonates only within the sharp peaks. The wavelength-selective mirror component is heated to adjust internal dimensions to maintain one of the sharp peaks at a selected emission wavelength. As optical signals pass through the wide tuning port, the signals are split between two channels of differing lengths resulting in optical interference. The optical interference limits the ability of the laser cavity to resonate at wavelengths other than near the center of a single broad peak determined by the relative lengths of the two channels. The wide tuning port is heated to vary the relative lengths of the two channels to maintain the single broad peak at the selected transmission wavelength. In this manner, the laser cavity is controlled to resonate substantially only at the single selected wavelength. Resonance at any of the other wavelengths reflected by the wavelength-selective mirror component is greatly limited, thereby significantly reducing transmission sidebands generated by the laser. Specific implementations of the ring resonator mirror and the reflective etalon are described.

A combustion system having at least one wall enclosing a combustion chamber and forming a plurality of burner or burner nozzle openings. Disposed within each of the openings is a premix burner or burner nozzle, each of which has a premixed fuel/oxidant outlet proximate the combustion chamber and a fuel/oxidant inlet distal from the combustion chamber. At least a portion of the premix burners or burner nozzles are sized to produce different fuel/oxidant delivery disturbance response times in response to a pressure disturbance within the combustion system. Differences in fuel/oxidant delivery response times are achieved by using burners or burner nozzles having different internal dimensions, different volume flow rates, and, optionally, by varying the fuel/oxidant ratios of the mixtures flowing through the burners or burner nozzles.
