Abstract: A swinging bucket centrifuge rotor including seating surfaces having shapes which cause buckets seating thereon to be relieved of side loading forces. Each bucket is symmetrical and is pivotally supported by bucket pins that rest in respective spring-loaded carrier assemblies. The spring constants of the springs of the carrier assemblies are selected so that the leading edge of each bucket bottom rests upon a curved surface and clears the respective seating surface before the trailing edge thereof contacts the same. The resulting bucket orientation assures that, upon seating, each bucket rotates until its bucket pins lift slightly off of the surfaces of the respective carrier assemblies.

Abstract: An overspeed protection signal override system disables the tach signal from a centrifuge rotor tachometer, so that the inverter-drive control circuit is unable to send a multi-phase motor drive signal to an A.C. induction motor, and the centrifuge rotor and motor are shut down, in response to an alarm signal from the overspeed protection circuit. The override signal is provided to assure that once the overspeed protection circuit of the centrifuge detects an alarm condition characteristic of rotor overspeed, the tach signal which drives the inverter is disabled and withdrawn from motor control, so that an A.C. induction motor will coast to rest even if the current control of the induction motor is not functioning properly.

Abstract: A centrifuge rotor (10) which comprises a rotor (10) having a plurality of radially extending arms (21), having a construction to matably receive a pin structure (32) within a recess (29) formed in the upper surface (26) of the rotor (10), to support the pin structure (32) against loads generated by centrifugal force without stressing a fastener (42). In assembly, the pin structures (32) permanently mount trunnions (58) for receiving a sample container (22), for pivotal movement, in a manner such that the trunnion (58) and sample container (22) cooperate to resist stresses and deformation caused by centrifugal loads.

Abstract: A method and apparatus for indicating quench associated with a liquid scintillation solution wherein the solution includes a sample, a solvent and a solute. The method includes exposing the solution to flashes of light, detecting a pulse height spectrum for scintillations produced in the solution in response to the light flashes, determining a unique point on such pulse height spectrum, and relating the unique point to a corresponding pulse height value, such pulse height value providing an indication of quench associated with the solution. The wavelength of light preferably excites essentially only the solvent and the light flash intensity and duration is such that the pulse height spectrum produced in response to the light flashes does not overlap a pulse height spectrum for the sample in the solution. An attribute of the shape of the light pulse height spectrum may be examined to provide an indication of the homogeneous or non-homogeneous nature of the quench present in the solution.

Abstract: Alignment of the image of a mirror reflecting surface bounding a fixed length optical path in an interferometer, with the reflecting surface of a moveable mirror bounding a second variable length optical path is obtained by directing the beam of a two frequency laser through the interferometer to obtain an existing beam containing a continual frequency modulation indicative of mirror alignment. The frequency modulation of the emerging beam is detected for phase comparison throughout its cross section to determine correct alignment. Control signals are obtained through the phase comparison of the beam cross sectional intensity to control mirror alignment by pivoting the mirror bounding the fixed length optical path about a central point of its reflecting surface thus substantially decreasing phase change introduced by mirror correction.

Abstract: A method and means for stabilizing the difference in frequency between component frequency modes of a gas laser influenced by Zeeman splitting is presented, comprising an electronic servo control loop which drives a magnetic flux element (40) for tuning the frequency separation of the component frequency modes and a thermal element (36) for tuning the length of the lasing chamber.
