The present invention is a container lid to be fitted on a container having materials used for constructions and/or maintenance of a structure and container lid facilitates mixing. Moreover, container lid has at least one mixer hole that is capable for permitting a portion of mixing paddle to pass through. When container lid is positioned over container, mixing paddle is rotated power drill, operated by a user, to mix materials within the container. Also, container lid has openings for permitting material/aid for mixing like water so that material/aid reaches container and enables mixing. Container lid and container are formed from existing material boxes like paintboxes, and hence such mixing is possible at a very low cost.

A surgical system including a surgical tool and a navigation system for tracking the position of the surgical tool. The surgical tool comprising a housing including a variable speed motor and control module disposed within the housing. The navigation system comprising a navigation console in communication with the control module of the surgical tool, the navigation console may be configured to communicate instructions to the control module of the surgical tool based on the position of the surgical tool relative to a defined zone. The navigation console may be configured to deactivate the surgical tool based on the position of the surgical tool relative to the defined zone. The navigation console may also be configured to provide a user-selectable override option to allow continued operation of the surgical tool within the defined zone.

An apparatus is disclosed for mixing substances, such as paint. The apparatus includes an elongate member with a plurality of openings formed within it. A filament is threaded through the openings creating bights between openings. The bights and ends of the filament sweep through the substance when the elongate member is rotated, which works to mix the substance.

Disclosed herein are devices, apparatuses, and methods for grinding of samples. A method includes securing a sample vial in a holder attached to a connecting linkage, the sample vial having a grinding media in the sample vial. The method includes rotating a crank that is operatively coupled to a proximal end of the connecting linkage at a proximal pivot point so that the proximal pivot point undergoes rotational motion. The method includes restricting a distal pivot point of the connecting linkage to a linear path, the distal pivot point near a distal end of the connecting linkage. A result being that the sample vial undergoes a combination of rotational and linear motion.

The present invention describes a rotating mixing/stirring device that includes a shaft (1) connectable to a rotational drive element, the rotating shaft (1) having sufficient length to accommodate at least one integral, substantially orthogonal blade or impeller (5). The blade or impeller (5) is driven to rotate by the rotating shaft (1) and thereby mix and stir any liquid in which the device is used. The blade or impeller (5) includes a plurality of apertures (6) arranged perpendicular to the rotating shaft (1) and these apertures are tapered.

A powered surgical tool that includes a housing with a head and a handle that extends from the head. An electric motor is disposed in the head. A trigger extends from the handle. There is a void space in the handle. A plate separates the motor from the handle. Internal to the handle void space there is a rotor sensor and a control circuit. The rotor sensor is able to monitor the magnetic fields emitted by the motor rotor and that pass through the plate. The control circuit receives signals from the rotor sensor representative of the rotational orientation of the rotor and is further able to monitor the actuation of the trigger. Based on the rotor orientation signals and the actuation of the trigger, the control circuit generates signals that result in the selective generation of power signals to the motor rotor.

A mixing attachment for use with a reciprocating mechanism of a reciprocating hand tool, to quickly and efficiently mix contents of paint cans or other containers, may include a support member and one or more retention ring assemblies. The support member may be disconnectably connected to the reciprocating mechanism. The one or more retention ring assemblies may be attached to the support member. The retention ring assemblies may be mounted in a longitudinal slot on the support member and include an adjustable band and a securing mechanism for tightening the adjustable band about an outer surface of a paint can.

The disclosure is directed to a sample preparation apparatus for grinding or homogenizing test samples. More specifically, the disclosure relates to grinding samples using rotational and linear motion. Grinding samples can be accomplished with an apparatus with a slider-crank mechanism that is attached to an oscillating connecting linkage. The amplitude of oscillatory motion can be greater than or equal to a length of a sample processing chamber.

Disclosed herein are devices, apparatuses, and methods for generating a reciprocating motion for the purpose of grinding or homogenizing samples. An apparatus includes a connecting linkage that extends along a longitudinal axis. The apparatus includes a sample vial holder attached to the connecting linkage. The apparatus includes a crank operatively connected to the proximal end of the connecting linkage, the crank configured to impart rotational motion to the proximal end of the connecting linkage. The apparatus includes a sliding carriage operatively connected to the distal end of the connecting linkage, the sliding carriage configured to restrict the distal end of the connecting linkage to a linear path. The apparatus includes a motor operatively connected to the crank to rotate the crank such that the sample vial holder, in use, moves with a combination of rotational and linear motion.

A drill assembly attachment having a handle, a drill mount, and a throttle. The throttle may have a first portion and a second portion rotationally engaged with the first portion such that the second portion is rotationally actuated in response to linear actuation of the first portion of the throttle. The throttle is positioned with respect to the drill mount and the handle such that the first portion may be linearly actuated by a user with a hand grasping the handle. The drill assembly attachment receives a drill assembly such that the throttle adjustably engages a trigger of the drill assembly. The drill assembly attachment or the drill assembly receives an auger or other tool and the drill assembly attachment with the drill assembly and auger or other tool is used in a method of rotating the auger or other tool.
