Abstract: A method for installing objects such as cabinets on a vertical surface such as a wall includes the use of a novel support device having an adjustable leg and an upper portion including two vertically spaced support surfaces. Two of the support devices are first placed at a selected height at an angle to the wall for initially supporting the object on a first support surface. The support devices are then sequentially moved to extend between a front portion of the object and the floor so that the object rests on the second support surface thus freeing both hands of the installer.

Abstract: A circular saw conversion table device supports a circular saw in position for use as a table saw. The device includes a panel having a top surface, a bottom surface, and a perimeter edge extending around and between the top surface and the bottom surface. A slot extends through the panel. A track is coupled to the bottom surface of the panel. The track extends around the slot. The track defines a lip configured for receiving and supporting a deck of a circular saw such that the a blade of the circular saw extends through the slot and projects from the top surface of the panel. A stand is coupled to the panel and configured for supporting the panel on a surface.

Abstract: A combined pad structure contains a disc base and a body. The disc base includes an anti-slid area defined on a bottom end thereof. The body includes a circular groove defined on a bottom end thereof to receive the disc base and includes a limiting portion formed on four corners of the bottom end thereof. Thereby, when the body is placed onto the disc base, the disc base is limited in the circular groove of the body, hence the body allows being rotated along the disc base. Also, when the body disengages from the disc base, they allow being used respectively, thus increasing using functions.

Abstract: A clamp mechanism for a workpiece having an oblique surface is provided. The clamp mechanism includes a base, a fixing member, and a locking assembly. The base includes a main body, a pivot shaft, and two holding portions on the main body which are away from the pivot shaft, and each holding portion defines a curved sliding slit extending around the pivot shaft. The locking assembly includes a locking member and an engaging member engaging with the locking member. The locking member passes through and slides along the sliding slits of the holding portions of the base. One end of the fixing member is rotatably connected to the base, and the locking member passes through the other end of the fixing member.

Abstract: A workpiece support having alignment features to allow the proper alignment of the shadow mask to the workpiece is provided. The alignment features include tactile sensors, so as to measure the pressure being applied to each alignment feature. Based on these pressure readings, a determination can be made as to whether the workpiece is properly aligned with the shadow mask. In some embodiments, corrective actions may be initiated if a determination is made that the workpiece is not properly aligned.

Abstract: A method and apparatus are provided, for positioning a work piece, such as a piece of crown molding, through use of an apparatus including a work piece support plate pivotably attached along a pivot axis to a base. The base is adapted to rest on a horizontal reference plane, such as the table of a mitre saw, for pivoting motion of the support plate about the pivot axis to a desired angle with respect to the base, while the pivot axis is simultaneously positioned to extend substantially parallel to a longitudinal line of intersection between a horizontal and a vertical reference plane, established by the table and fence of the mitre saw, to hold the work piece at a desired tilt angle with respect to the vertical reference plane, so that the work piece may be cut in substantially the same orientation as it will be mounted.

The base includes a main body, a pivot shaft, and two holding portions on the main body which are away from the pivot shaft, and each holding portion defines a curved sliding slit extending around the pivot shaft. The locking assembly includes a locking member and an engaging member engaging with the locking member. The locking member passes through and slides along the sliding slits of the holding portions of the base. One end of the fixing member is rotatably connected to the base, and the locking member passes through the other end of the fixing member.

Abstract: A lift mechanism includes a balance structure configured to hold an object, wherein the balance structure is rotateably connected to an arm structure at a pivot point. The pivot point is configured, and the object is positioned, such that the pivot point is substantially coincident with the center-of-mass of the object being moved. Weights may be selectively attached to the balance structure to adjust the center-of-mass. In one embodiment, the lift mechanism includes a base and an arm configured to rotate with respect to the base, wherein the arm is attached to the balance structure at the pivot point. In this way, heavy objects may be lifted, translated, and rotated into place safely in an efficient manner.

Abstract: A basket assembly fixture is useful in the construction of a basket assembly for interring spent nuclear fuel rods. The basket assembly fixture has an elongate base and a pair of lifting beams disposed above the base. Lifting beam raising means are provided at both ends of the base to raise the pair of lifting beams. A transverse beam is provided below the two lifting beams and above the base. Transverse beam raising means are provided for raising the transverse beam.

Abstract: Ready-to-use preshaped, prefabricated cured structural components are prepared in a variety of shapes and sizes to be used in the fabrication of dental appliances. Preferably the structural components are fabricated of a fiber-reinforced composite material or a particulate-filled composite material comprising fibers or particulate filler impregnated with a polymeric matrix. The polymeric matrix is partially or fully cured to the point of sufficient hardness to provide a ready-to-use structural component for use in the fabrication of dental appliances such as orthodontic retainers, bridges, space maintainers, tooth replacement appliances, splints, crowns, partial crowns, dentures, posts, teeth, jackets, inlays, onlays, facings, veneers, facets, implants, abutments, cylinders, and connectors.

Abstract: A workholder or roll-over fixture including a primary supporting structure and a pair of workholding elements mounted for rotation in the structure about a fixed axis of rotation and providing a work-receiving area therebetween. The workholder is particularly suitable for servicing and maintaining large and heavy machinery. The workholder includes a control system including a sensing means that is sensitive to out of balance forces within the workholder caused by rotation of the workpiece when held by the workholding elements and movement of the center of gravity of the workpiece relative to the axis of rotation. This control system also preferably includes a device mounted on one of the workholding elements which is adapted to sense the attitude thereof. The sensing means provides an output signal, which is sent through the attitude sensing device, indicative of the out of balance forces.
