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 invention discloses a mahjong machine, a mahjong tile jacking component and a method for settling mahjong tiles. A mahjong tile storage slot of the mahjong tile jacking component is bent in an arc-shaped form and the bending angle is greater than 180 degrees; the mahjong tile jacking component is equipped with a first arc-shaped mahjong tile storage part and a second mahjong tile storage part in different bending radiuses; the mahjong tile jacking component comprises a mahjong tile pushing slide block base, a mahjong tile pushing block and a mahjong tile jacking push rod which are arranged on a mahjong tile jacking bracket; the mahjong tile pushing slide block base is driven to rotate around a fixed point by a mahjong tile jacking motor; a mahjong tile pushing slide block is in sliding connection with the mahjong tile pushing slide block base; the mahjong tile jacking push rod is fixedly connected with or integrally manufactured with the mahjong tile pushing slide block; a mahjong tile jacking push head is arranged on the mahjong tile jacking push rod; a cam slot matched with the mahjong tile pushing slide block is formed on the mahjong tile jacking bracket. According to the scheme, four sets of mahjong tile picking carrying systems of the mahjong machine are respectively and independently arranged and are not intersected with each other; a structure without a mahjong tile rotating device or stacking head is adopted, so that the problems that the stacked mahjong tiles are pushed bias, are tightly blocked and cannot be pushed into the mahjong tile storage slot can be avoided; the height of the main frame of the mahjong machine and the manufacturing cost are lowered; the usage experience and comfort level are higher.

The present disclosure relates to a wearable dialysis system and method for removing uremic waste metabolites and fluid from a patient suffering from renal disease. Uremic waste metabolites can be removed by a wearable peritoneal dialysis device that regenerates the peritoneal dialysis solution without removing positively charged, essential ions from the solution and, consequently, the patient. Fluids can be removed from the blood of the patient by an implantable fluid removing device. Fluids are delivered to the bladder and preferably removed from the body of the patient through urination. The wearable dialysis system may be operated continuously or semi-continuously and be comfortably adapted to the body of the patient while allowing the patient to perform normal activities.

An endpiece for applying a cosmetic or care product, the endpiece comprising a first part assembled with a second part, one of the two parts defining at least part of an applicator surface suitable for being fed with substance by at least one orifice of the endpiece, the second part having a coating of flocking extending:at least to an edge portion of said second part, said edge portion being substantially in contact with a non-flocked corresponding edge portion of the first part; and / orto a line situated substantially in contact with a non-flocked corresponding edge portion of the first part, the surface of the second part to which the flocking bristles are attached being set back from the outer surface of the edge portion of the first part.

A keyboard of reduced size is provided in which multiple characters are assigned to each of the primary keys. The selection of the characters to be assigned to each specific primary key is based on the touch typing rules associated with a specific standardized keyboard, preferably allowing at least three rows of keys to be reduced to a single row of keys. A disambiguating system is used to interpret which of the characters and / or symbols assigned to a particular key is intended, typically by applying a set of disambiguating rules to generated input sequences.

An applicator capable of applying a substance, in particular a cosmetic or care product, on the eyelashes or eyebrows, the applicator comprising an open support defining at least one opening situated between two opposite regions of the support, with protruding elements connected to at least one of said regions and extending towards the other region.

Various uses and constructions for an open sided nozzle for a surface cleaning apparatus are provided. Alternate constructions for a surface cleaning head are also provided.

The invention discloses an automatic nursing bed, which comprises a bed body, a nursing bed mattress, a defecation absorption seat, an automatic defecation absorption seat turnover assembly and a defecation collection treatment assembly. The automatic defecation absorption seat turnover assembly comprises a cross beam fixedly arranged on a nursing bed frame, a pull rod bracket is fixedly arranged on the cross beam, a pull rod capable of moving along the axis is arranged in the pull rod bracket, and an absorption seat turnover sleeve and a plugging plate turnover sleeve capable of rotating along the pull rod respectively are sleeved on the pull rod; a defecation absorption seat mounting stand is arranged on the absorption seat turnover sleeve, and a nursing hole plugging plate is arranged on the plugging plate turnover sleeve; the end of the pull rod is provided with a pull rod length adjusting device which is connected with a pull rod pushing device for driving the defecation absorption seat mounting stand or the nursing hole plugging plate to move to the lower part of a nursing hole; and the bed frame is also provided with a turnover driving device in power connection with the absorption seat turnover sleeve or the plugging plate turnover sleeve. The automatic nursing bed well combines defecation and nursing together, has reliable operation and comfortable use, realizes humanized nursing service, and saves time and labor.

An earphone device having composite functions at least has an earphone shell body, a loudspeaker, and an adjustment component. Several outer sound holes are disposed on the outer side of the earphone shell body. The loudspeaker is fixed in the earphone shell body. The loudspeaker is arranged outwards. The adjustment component is disposed on the earphone shell body. There are several adjustment holes corresponding to the outer sound holes of the earphone shell body on the adjustment component. The adjustment holes of the adjustment component can be controlled to be opposite to or be staggered with the outer sound holes of the earphone shell body. The earphone device is comfortable for use and can reduce pathological changes in ear and hearing decay to keep the human body healthy. Moreover, the earphone device has the functions of earphone, sound amplifier, and sound box.

An artificial joint for implantation into a subject's body is provided which includes an outer race coupled with fixation means to anchor the outer race within an existing joint socket. An inner race member seats within the outer race and a first bearing member is juxtaposed therebetween. The first bearing member has its normal axis closely coincident with a center of rotation that is normal to an axis of most frequent movement of the joint. The bearing component is installed in an alignment that supports loads on a primary axis. A second bearing member may be provided between the inner and outer race members which constrains forces generated during use of the joint and centers forces onto the first bearing member.
