Abstract:
An auxetic locking structure can be used as a mechanism for securing two or more members in an assembly or other system. The locking structure has void patterns on its exterior surface which permit the locking structure to reduce its outer diameter upon loading in an axial direction. Once the structure has been sufficiently loaded and the diameter has been sufficiently reduced, the locking structure may be positioned within a bore of an article, the axial load is then reduced, thus causing the locking structure to expand and engage the bore of the article. The locking structure and article are now secured to one another creating an improved assembly.
Abstract:
Disclosed is a permanent magnet motor for a washing machine. The permanent magnet motor comprises a stator including stator teeth and stator slots, a stator coil being wound on the stator teeth, and a rotor rotating about a rotor shaft, including rotor teeth, a permanent magnet and a bushing, the rotor being spaced from an inner circumference of the stator.
Abstract:
An apparatus, comprising a microfluidics system having an insertion slot for insertion of a droplet actuator; a bottom plate against which the droplet actuator would slide when inserting the droplet actuator into the insertion slot; and means for forcing a substrate in the droplet actuator parallel to the bottom plate, wherein warpage in the substrate is corrected.
Abstract:
An oral care implement, e.g., toothbrush, having a wick applicator and a method of assembling the same is disclosed. The implement includes a head, a handle connected to the head by a neck portion, and a recess. The recess is arranged for receipt of the wick applicator. The handle includes an internal fluid reservoir holding a fluid in communication with the recess. The wick applicator is arranged to enable a fluid to pass therethrough by capillary action and has a first end portion and a second end portion. The second portion of the wick applicator comprises at least one projection for engaging at least one cooperating portion of the recess to secure the wick applicator in the recess at an operative position, whereupon the wick applicator is in fluid communication with the fluid in the reservoir.
Abstract:
A part (2) made of pyrolytic carbon and another part (1) for example made of metal, are assembled with one another by snap-fastening obtained by elastic deformation of the part (2) made of pyrolytic carbon and are shaped in such a way that, thus assembled, the part (2) made of pyrolytic carbon remains subjected to deformation stresses resulting from the snap fastening, so as to perform a resurfacing function.
Abstract:
An injection site (18) for a medical fluid container (10), along with a procedure facilitating the automated assembly of the injection site (18). An oversized, compressible situs (22) is mounted in a generally tubular port (20) which includes a needle-piercible membrane (24). The top (26) of the tubular port (20) is tapered inwardly so that the opening (30) defined by the tapered top end (26) has a diameter that is less than the diameter of the volume (28) defined by the tubular port (20). Thus, the tapered top (26) maintains the situs (22) in a state of compression within the tubular port (20) and minimizes inadvertent removal of the situs (22).
Abstract:
An assembly apparatus adapted to assemble a first member to a second member includes: a base; a positioning module mounted on the base and adapted to position the first member and the second member; and an expanding module mounted on the base and adapted to expand outwardly the distance between a pair of elastic legs, so as to allow the second member to be place d between the pair of elastic legs. After the pair of expanded elastic legs of the first member is released by the expanding module, the second member is clamped by the pair of elastic legs of the first member, and protrusions of the second member are fitted into installation holes of the first member, respectively. The assembly apparatus may achieve the automatic assembly of the first member and the second member.
