摘要： A system for automatically centering and rigidly retaining a mixer shaft in a mixer drive. A hollow quill in a mixer drive is provided with an axial bore having a first diameter along a central portion thereof and tapering linearly and axially in opposite directions away from the central portion with increasing diameter to define a pair of opposed conical portions of the axial bore on either side of the central bore. A smooth-surface cylindrical mixer shaft inserted into the bore is retained by the tightening of upper and lower tapered cylindrical locks which are slidable along the mixer shaft and have conical outer surfaces which are matable with the upper and lower conical portions of the quill bore. The locks, when urged into wedged relationship between the shaft and the quill bore, automatically center the shaft in the quill in rigid retention. The upper end of the shaft is provided with a thrust plate secured by throughbolts into the quill to press the upper lock into locking relationship. At the lower end of the quill, a bearing retainer ring threaded onto the outer surface of the quill is bored to receive bolts extending through a flange on the lower lock to press the lower lock into locking relationship. The rigidity of the lock increases the first critical frequency of the mixer system and therefore permits operation at high speeds, including rotational frequencies greater than the first critical (natural) frequency of the mixer system.

摘要： A mixer seal assembly for a closable vessel having a dynamic mixer shaft seal in a bore in a vessel flange and a static seal for vessel transport formable by insertion of a disconnected lower portion of a fast connect coupling which is fast to install on the mixer shaft into the flange bore above the dynamic seal. The resulting seal assembly can seal the vessel for over-the-road transport. The dynamic seal includes a circular lip which sealingly engages the surface of the mixer shaft. The static seal includes an O-ring disposed in a first annular groove in the coupling portion. A shaft bushing disposed adjacent to the shaft seal in the flange bore minimizes shaft runout in the shaft seal and permits use of relatively rigid and dry running materials such as fluorocarbon polymer in the shaft seal. In the shut-off position with the coupling portion inserted into the vessel flange, a spring pin mounted in the vessel flange can engage a second annular groove in the coupling portion to lock the coupling portion in the flange bore. In an alternative embodiment for use in retro-fitting existing vessels, the vessel flange of the invention may be configured to sealingly conform to an existing vessel flange.

摘要： An optical focus sensing system is disclosed. The system provides a focus shift measurement capability utilizing the relative motion between two gratings to produce different diffraction orders which are separately detected by a pair of detectors to form signals having a phase difference proportional to the focus error corresponding to the planes occupied by the two gratings. A control circuit is responsive to the phase difference between the signals from the two detectors to provide a controllable focusing capability.

摘要： A frame synchronization detection system which enables frame synchronization and synchronizing pulses to be provided from at least two formats of DS1 TDM signals, specifically the D4 and extended superframe Fe formats. A first search logic circuit provides an output indicating the onset of a maintenance mode of frame detection when either Fe or D4 patterns are decoded. For the D4 pattern an alternate pattern is decoded and the first search circuit enters the maintenance mode only after both alternate D4 framing patterns are decoded. A second search logic circuit enables the decoding of a subsequent sequence and detection of framing, thereby reducing the probability of false framing. A frame counter which is synchronized upon the detection of a valid framing pattern by the first search circuit continues to supply frame sync pulses until an error detector, which detects whether a predetermined ratio of invalid to valid framing bits occurs, resets the system back to the search mode.

摘要： An end connection for a shaft made of composite material, which accommodates for differences in stiffness, thermal expansion, chemical resistance between the shaft and the member connected thereto and operates under oscillating torque, thrust, and bending loads, and also provides for manufacturing flexibility in enabling the shaft and connection to be produced as separate parts which are formed when final assembly is to occur. The connection has a male insert which is inserted into the end of the composite shaft. Axial and circumferential grooves in the surfaces of the male insert and the shaft. These grooves are aligned to form circumferential and axial keyways which intersect each other. Material is injected into the keyway and polymerizes to form structural keys which transmit the thrust and torque, while locking the insert member and the shaft permanently together. The bending loads are transmitted through the tight fit extending axially between the shaft, insert member and keys. The radial thickness of the end of the shaft, the amount and orientation of the reinforcing fibers therein and the insert are matched so that their stiffness index approximately match. The composite shaft may be connected to a mixing impeller to provide a reliable support and drive therefor.

摘要： A railway track switch, also known as a switch machine, is controlled by a microprocessor switch lock connected to the electric switch lock of the switch machine and permits the switch machine to be unlocked so that the track switch points may be thrown, as by a hand-throw mechanism, to permit movement of a train between main and secondary tracks. The switch lock is connected to a cut section repeater of the track circuit adjacent to the track switch. An overlay track circuit connected to the main tracks indicates occupancy in the vicinity of the track switch. The microprocessor receives signals from the repeater, the overlay circuit and the electric switch lock of the switch machine indicating track occupancy and requests to unlock the track switch so that the switch points may be moved. Signals are also received from a timer as to specific, selected delay times set by the user before unlocking the switch. An interface also controls the microprocessor to decode occupancy and other track codes, transmitted by the track circuits and received by the repeater, as are selected by the user to enable the apparatus to be used with any track circuit communication code protocol. The microprocessor cooperates with a hardwired counter and is programmed to provide continuous checks for vital operation.

摘要： Mixing systems for liquids having fibers suspended therein wherein the fibers tenaciously adhere to and accumulate on the leading edge of the impeller, thereby increasing the drag of the liquid on the impeller as it rotates and the consequent increase in the power required to rotate the impeller. Axial flow of the liquid in a tank is produced by the impeller within a draft tube. The leading edge of the blades of the impeller are inclined with respect to radial lines extending from the axis of rotation of the impeller beyond the angle of repose of the fibers on the leading edge. Also, the coefficient of friction of the portion of the impeller, extending from the leading edge toward the trailing edge thereof, to which the fibers adhere is reduced by providing the surface thereof with a low coefficient of friction material.

摘要： The mixing of liquid and liquid suspensions in vessels is obtained by a mixing impeller mounted on a shaft and rotated by a drive which delivers selected speed and torque. The torque and power needed to obtain given flow is minimized by a low-cost impeller having a plurality of blades, each formed from a plate of constant thickness except for a leading edge of rounded profile. Each blade has camber which decreases from the tip to the base thereof. The base can be flat to facilitate the attachment of the blades to the shaft. The blades are oriented and twisted to be at the threshold for flow separation along the width of the blades from the leading to the trailing edge thereof, thereby providing maximum flow in the axial direction before the onset of flow separation. The orientation and twist of the blades provides a generally constant angle of attack along the entire blade from tip to base and the planform of the blade provides for uniform loading, stability and minimization of fluid forces which tend to bend the shaft.
