Composition and methods that include potassium nitrate for whitening and/or reducing tooth sensitivity. The dental compositions may optionally include a dental bleaching agent, such as hydrogen peroxide or carbamide peroxide. The dental compositions may be applied directly to the person's teeth, or they may be loaded into a comfortable fitting, flexible, thin-walled dental tray and placed over the person's teeth. In that case, the dental compositions will include a tackifying agent, such as carboxypolymethylene, dispersed within a solvent, which assists the composition in retaining the dental tray over the person's teeth as a result of the adhesive properties of the dental composition rather than due to mechanical interlocking of the tray over the person's teeth. The dental compositions may further include anticariogenic and antimicrobial agents.

The recesses and protrusions terminate in a vertex; the vertex has a planar, or two-dimensional, configuration that is parallel to either-the blade centerline or the sipe centerline.

A holder for supporting a bag having handles in an open position is disclosed. The holder includes a mounting member to removably mount the holder to a support structure, and a pair of support arms which interlock with the handles of the bag during use. The support arms extend from the mounting member, include a pair of notches on an upper edge thereof, and a pair of cutout portions on the bottom coners of each support arm.

The gap in the cylindrical base has a first tab on the first edge and a second tab on the second edge. The first tab is adapted for coupling to the second tab and thereby prevents the interlocking of one tolerance ring with another. The gap can be configured to be non-linear.

A container assembly comprising a body and interlocking and self-actuating lid. The body has a bottom and at least one sidewall extending generally upwardly and includes at least one body interlock piece. The lid includes a lid interlock piece configured to releasably engage the body interlock piece. A first magnet is coupled to the body and a second magnet is coupled to the lid.

An exhaust manifold for connecting an exhaust pipe with at least one cylinder of an internal combustion engine, and a shell manifold as at least one component of the exhaust manifold. The at least one shell manifold (3, 9, 17, 31, 38) is comprised of at least two shape shells (4, 14, 10, 20, 18, 28, 32, 34, 39). The shape shells are joined to each other by mechanical interlocking. The shell manifold exhibits at least one inlet (5, 11, 19, 35, 46). The shell manifold (3, 9, 17, 31, 38) is so designed, that the at least one inlet (5, 11, 19, 35, 46) communicates with the at least one cylinder.

Stackable weight plates comprised of a front and a rear lateral faces with a protrusion at a proximal radial center of the front lateral face and corresponding recess at a proximal radial center of the rear lateral face is provided. The rear lateral face with the recess section at the proximal radial center of a top weight plate in a stack may rest (or be stacked) on the front lateral face with the protrusion at a proximal radial center of another weight plate. Because each plate is restrained along its center axis by the mating or interlocking of the protruded area of one plate with the recessed area of another weight plate, the stacked plates are therefore generally stable and do not fall due to lateral shearing of the stack. When mounted on a handle bar to form an inertial force exercise device, the recessed area of the rear lateral face of the weight plates of the present invention house the mounting or fastener mechanism.

Both a mold blade for forming sipes and the sipe so formed in a tire tread element have three-dimensional portions. In the formed sipe, the three-dimensional portion creates a constant interlocking of the opposing sipe faces. The blade and the sipe have two radially adjacent rows of projections, wherein the projections are separated by a planar section, the planar section having a defined length and width.

The invention, which belongs to the technical field of the power system and automation realization, discloses a phase modifier emergency control method and system capable of suppressing a direct-current consequential commutation failure. The method comprises: a direct-current commutation failure information sub station sends direct-current commutation failure information to an emergency control master station; the emergency control master station obtains bus voltage information of a direct-current inverter station with a commutation failure and all phase modifier operation information in a grid; the emergency control master station matches a proper emergency control measure from a control strategy table and sends the measure to a phase modifier control execution station; and the phase modifier control execution station sends an excitation reference voltage modification instruction and a duration time instruction to a phase modifier excitation system to complete phase modifier emergency control. According to the invention, because participation in grid emergency control is realized by using the phase modifier, a direct-current consequential commutation failure probability of a multi-direct-current feed-in receiving end is reduced, interlocking of the direct current due to multi-times commutation failures is prevented, and the large-area power outage caused by multi-direct-current interlocking can be prevented.

Modular structures constructed from interlocking wall modules made of plate steel and assembled with C-channel connectors, including tongue and groove elements used to position adjoining modules adjacent to one another, for example during the construction of a cell block. The tongue and groove elements ensure all adjacent prison cell modules are properly aligned such that the front fascia of each cell module lies within substantially the same plane. Further, the interlocking of the tongue and groove allows for the quick, cost-effective construction of a schoolroom having double skinned walls in an effort to increase the stability of the structure. Lastly, the interlocking panels may be formed in relatively small sections and then joined together in order to form a larger wall.
