Rotation activated drum tuning system

A drum tuning system which rotates clockwise or counterclockwise to adjust the tension of a drum head fitted over the open end of a drum body. It utilizes a rotating ring having numerous opposing equally spaced vertically projecting tabs along the top of the body's diameter, each with inward facing wheels that ride on the horizontal surface of a separate inner hoop bearing down on the drum head. The rotating actuator ring is fitted with multiple radial cleats projecting from its outside diameter for grasping it. A radius plate having horizontal holes extends from the drum body, and a tool engages the radial cleats on the rotating actuator ring to facilitate rotation. Multiple adjustable eccentric lugs are used to raise and lower the drum camming mechanism in relation to the open end of the drum body where attached. Horizontal projecting links support the drum attached to suspension mounting systems.

High resolution, dynamic positioning mechanism for specimen inspection and processing

A specimen positioning mechanism (10) includes a movable stage (12) movable along multiple axes, a plate (35) connected to and supporting a specimen mounting chuck (14), multiple linear displacement mechanisms (36, 38) coupling the plate to the movable stage and mutually spaced apart at different locations between the movable stage and the plate and separately controllable to change distances between the movable stage and the plate, and a flexible member (22) coupling the movable stage and the plate. The flexible member is motion compliant in three axes of motion. The flexible member in response to linear displacements of the linear displacement mechanisms allows linear and rotational movement of the specimen mounting chuck in the three axes of motion compliance.

System and method for harnessing wind power at variable altitudes

A system for harnessing power from wind using a wind capturing structure. An axis of rotation could be central to the system, and the lines could rotate around this axis. Features for the wind capturing structure include effective downwind power generation using a durable, lightweight, inexpensive structure that may be safe in the event of a crash, and easily modified to reduce drag for retraction. The capturing structure creates lift in a low altitude environment, capable of operating in high wind conditions. The lines include minimal mass to permit lift at low altitudes, and are constructed with maximum tensile strength to prevent failure in high winds. A versatile wind capturing structure could include a kite operable in variable conditions for efficient and consistent production of force. The power producing cycle of a system capturing power from wind should maximize the efficiency of the system.

Collimation apparatus for radiotherapy

A radiotherapy apparatus comprises a means for producing a beam of radiation directed along a beam axis and having a width in first and second directions transverse to the beam axis, a multi-leaf collimator for selectively limiting the width of the beam in at least the first direction, a block collimator for selectively limiting the width of the beam in at least the second direction, the block collimator comprising a diaphragm moveable into and out of the beam and having a thickness in the direction of the beam axis that varies. The diaphragm can have a front edge of greater thickness than at least one region behind the front edge. It can also have a spine region extending from a rear part thereof towards the front edge that is greater thickness than at least one region displaced laterally with respect thereto. Together, these can cover the areas that will not be fully shadowed by a dynamically moving MLC. A control means for the multi-leaf collimator can be arranged to extend leaves of the multi-leaf collimator to shadow regions of the beam that are blocked by a relatively thinner section of the diaphragm. This is made easier if the spine region extends from the rearmost part of the diaphragm, the spine region extends to the front edge of the diaphragm, the spine region is straight, the spine region is a central region of the diaphragm, and if the width of the spine region increases towards the front edge of the diaphragm. The present invention also relates to a radiotherapy apparatus comprising a multi-leaf collimator and a block collimator, the block collimator comprising a diaphragm with variable thickness, and to a block collimator for use in radiotherapy apparatus comprising a diaphragm moveable into and out of a beam, and having a thickness in the direction of the beam axis that varies.

Specimen Holder For Microscopy

InactiveUS20080174862A1Low production costReduces and eliminates Z-axis driftMicroscopesMicroscopeEngineering
The present invention relates generally to microscopy and, more particularly, to a novel specimen heating and retaining assembly designed to eliminate or reduce z-axis drift during microscopic examination of heated specimens. Attributes of the novel system of the present invention include that it has a minimal thermal mass allowing temperature to be changed / controlled more rapidly. Additionally the heat dissipated by this minimal thermal mass is insulated from the stage of the microscope which greatly reduces the thermal expansion of the scope stage and scope body. The support surface of the heated plate is coplanar with the specimen plane so that the dimensional changes that occur due to changes in heat do not affect the Z axis position of the specimen. The novel system of the present invention is also adjustable so that the end user can compensate for variations in the thicknesses of a variety of commercially available plastic ware and glass slides.

InactiveUS20050042063A1Additional freedomShorten effective lengthLifting devicesLoading/unloadingEngineeringVertical distance
A storage and retrieval unit comprises in a known manner a supporting carriage which is movable along a rack aisle on at least one substantially horizontal supporting rail. A lifting platform intended for receiving storage items is taken along by the supporting carriage in the horizontal movement and can be moved relative to it in the vertical direction with the aid of a lifting apparatus comprising at least two traction means on which the lifting platform is suspended. In order to prevent the lifting platform from swinging out in the lateral direction, a stabilising device is provided. The latter comprises a stabilising carriage which is movable by means of its own drive along at least one guide rail running at a vertical distance from and parallel to the supporting rail. A substantially rigid connecting structure having a horizontal extension component is articulated both on the lifting platform and on the stabilising carriage. The horizontal distance between the lifting platform and the stabilising carriage is changed by means of a control system, by corresponding movement of the stabilising carriage, in such a way that the lifting platform can perform only the desired, in particular vertical, movement relative to the supporting carriage. This storage and retrieval unit has only very small masses which can oscillate and are to be accelerated.
