A vapor deposition reactor includes a chamber filled with a first material, and at least one reaction module in the chamber. The reaction module may be configured to make a substrate pass the reaction module through a relative motion between the substrate and the reaction module. The reaction module may include an injection unit for injecting a second material to the substrate. A method for forming thin film includes positioning a substrate in a chamber, filling a first material in the chamber, moving the substrate relative to a reaction module in the chamber, and injecting a second material to the substrate while the substrate passes the reaction module.

An insert comprising a lightweight structure configured for filling the gaps between axially spaced C-shaped lamination stacks and circumferentially spaced non-magnetic cradles on a permanent magnet rotor. The insert is secured to a rib by a dovetail tongue that fits within a dovetail groove provided along the length of each rib. The insert engages the adjacent cradles and has a circumferential surface that has the same radius of curvature as the top surface of the cradles.

An optical coherent receiver in one embodiment has a heterodyne configuration, and in another embodiment has a homodyne configuration, in each configuration employs multiple feedback signaling and analog / digital processing to optimize response to a modulated optical input signal, the provision of both individual RF I and RF Q channel outputs.

The present invention comprises an apparatus and method for efficiently venting impurities from a heat recovery steam generator system by concentrating the impurities in a condensing deaerating vent line 40 and then venting a proportionately small amount of steam with a proportionately high concentration of impurities. The condensing deaerating vent line 40 is attached to a low pressure drum 10, and feed water 54 may be added to the upper portion of the condensing deaerating vent line 40 to improve condensation and conserve thermal energy.

A dolly on which a grand piano can be mounted to facilitate movement thereof over a surface from one location to another, which includes a central hub shaped in the form of a miniature grand piano, two fixed length arms of equal length pivotally connected to the front of the hub at opposite corners thereof, and a fixed length rear arm having a longitudinal slot which is pivotally connected to the rear of the hub at selectively adjustable positions along the length of the slot to accommodate grand pianos having a range of different lengths.

A polyphase electrosurgical system and method are provided. In embodiments, a radiofrequency generator having the capability of delivering a plurality of independent electrosurgical signals is disclosed. An electrosurgical instrument having an array of electrodes that correspond to the plurality of signals may be used to deliver the electrosurgical signals to tissue. In embodiments, three RF signals having a phase offset of about 120° therebetween, i.e., a three-phase configuration, may be used to achieve a balanced delivery of electrosurgical energy, which may lead to increased rates of energy delivery, improved control of tissue ablation regions, and improved operative outcomes. The phase, amplitude, and / or frequency of each signal may be independently variable in response to user inputs and / or biological parameters such as tissue impedance or return electrode current.

An apparatus for ejecting a flying body such as a payload recovery container from a spacecraft includes a first ring to be releasably engaged with the flying body, a second ring to be secured to the spacecraft, and tension cables extending between and interconnecting the two rings. Cable winding devices mounted on at least one of the rings are spring-biased to wind-up the cables. The flying body is inserted through the open inner diameter of the second ring, and the first ring is separated from and rotated relative to the second ring, so that the cables extend helically along the outer circumference of the flying body. Holding and guide elements on the second ring hold and guide the flying body. When the holding elements are released, the cables are retracted by the cable winding devices, whereby the flying body is rotated and translationally ejected through the second ring.

The present invention relates to a safe valve for a high pressure regulator, which includes: a guide body coupled to a valve port prepared at a body of a high pressure regulator; a valve body couple to an upper end part of the guide body to open the valve port when the overpressure occurs in a state that the valve port is closed; a lower spring installed inside the valve body for providing elastic force to the valve body; and a discharging pipe couple to a lower part of the guide body for discharging the fuel upon an opening operation of the valve body, wherein a function for a relief valve to relieve the overpressure by discharging the fuel when the overpressure is generated inside the high pressure regulator and a function for a purge valve separated from the body to discharge fuel inside the high pressure regulator are integrally provided.

A method of treating hydroxide alkaline waste and by-products to render the material neutralized or reduced in pH from near 14 to a minimum lower limit of about 5.3 based on aluminum poly cation salts, rendering the waste or by-product stream suitable for ultimate disposal or reuse. The method comprises contacting together a mixture of moderate to high alkaline waste or by-product material with a pH in the range of 7.5-14, with sufficient water added or found within the alkaline material, with one or more poly cationic salts in the dry form taken from a group of salts containing tri-valent aluminum, tri-valent iron, di-valent calcium, di-valent magnesium, di-valent manganese, di-valent zinc, or any polyvalent cationic salt that is soluble in water to a minimum extent of 0.5 grams per 100 milliliters of water at near 0° Centigrade and 2 grams per 100 milliliters of water at near 100° Centigrade, in such a way to cause these materials to interact in a double replacement reaction to form a soluble salt reaction by-product and an insoluble hydroxide precipitate with water solubility characteristics, between 0° Centigrade and 100° Centigrade, equal to or exceeding that of CaS04*2H2O (gypsum) or approximately 0.20 grams per 100 milliliters of water. The added salts) may be dry or made up of a brine or dilute salt solution of the chosen salt or salts from the set of poly cation salts suitable to reduce hydroxide alkalinity in waste and by-product materials causing the pH to drop immediately upon thorough mixing of the poly cation salts and the waste / product materials, resulting in a treated waste / by-product stream / that is suitable for ultimate disposal or re-use.

An apparatus for ejecting a flying body (e.g. payload recovery container) from a spacecraft includes a first ring to be secured to the spacecraft, a cable winding device that is arranged on a second ring and that is releasably engageable with the flying body, and tension cables extending between the two rings. The cable winding device is spring-biased to wind-up the cables, which extend axis-parallel along the cylindrical outer shell of the flying body. Holding and guide elements on the first ring hold and guide the flying body. Catch elements on the cable winding device releasably engage receivers on the flying body. When the holding elements are released, the cables are retracted by the cable winding device, and the rotation of the cable winding device is transmitted to the flying body via the engaged catch elements and receivers. Thereby, the flying body is rotated and translationally ejected.

The present invention is directed to improved designs and methods for improving engine fuel efficiency by providing two-stage engine variable compression in running engines using connecting rod force reversals to rotate eccentric bushings to change the connecting rod length. Compression ratio changes are initiated by shifting a block-mounted cam such that it engages and flips a bi-stable toggle on the connecting rod. The clutch mechanism latches the eccentric at the eccentric rotation end point, whereupon the connecting rod acts as a rigid rod. The invention includes novel configurations of the lubricated journal bearing between the connecting rod and the eccentric that modify the squeeze film bearing effects and resulting friction. These configurations reduce the peak eccentric torque carried by the clutch mechanism while facilitating eccentric rotation at lower torque.
