Abstract: A bird feeder includes a seed reservoir formed as two or more telescopic components, which are reducible in size when not in use and which may be telescopically expanded by the owner thereof when in use to define a full-length seed reservoir. The bottom end of the reservoir is received in a base having a conically-shaped seed spreader situated therein, and the upper section of the reservoir is mounted to the underside of a hemispherically-shaped, anti-squirrel dome.

Abstract: Provided are a fusion protein of Exendin-4 and its analog, the preparation method and use thereof. The fusion protein is obtained by fusing of Exendin-4 or its analog to Fc region of human IgG2 via a linking peptide, which has the better stability and prolonged serum half-life, and can be used for treating diabetes and obesity.

Abstract: A pet grooming tool includes a handle having a proximate end on which is mounted a set of rear blades and a set of forward blades. The rear blades are interleaved with the forward blades. Each blade includes a hooked end having a curved, outer tip which is unsharpened, and an inset sharpened blade edge. The rear blades and forward blades are offset in both a forward-to-rear orientation and a side-to-side orientation to cause the fur or hair of the animal being groomed to form a soft “S” shape or bend over the sharpened blade edges.

Abstract: A battery cover assembly (100) includes a housing (10), a button assembly (20), a driving assembly (30), and a back cover (40). The button assembly includes a button portion (21) and a first latching portion (23). The back cover has a second latching portion (451). The driving assembly is configured for driving the back cover along a second axis. The button assembly is mounted on the housing and is movable along a first axis. The back cover covers the housing and is movable along the second axis. The first latching portion engages with the second latching portion in order to lock it to the back cover. When the button portion is pressed to move along the first axis, the second latching portion disengages from the first latching portion, and the back cover is moved along the second axis, under the force of the driving assembly.

Abstract: A portable electronic device includes a housing defining a first chamber and a second chamber and forming a separating wall between the first chamber and the second chamber, and a cover attaching to the housing. Two batteries are respectively received in the first chamber and the second chamber.

Abstract: A pet comb device includes a comb assembly having two comb members mounted together and each comb member having a number of teeth formed in the bottom portion for forming a number of slots between the teeth, and the teeth of the comb members are offset from each other and arranged in a stagger-way for suitably and effectively engaging with a hair of a pet. The comb members each include an outer covering applied onto an outer peripheral portion of an inner core element, and the teeth of the comb members each also include an outer covering applied onto an outer peripheral portion of an inner core element of the teeth for increasing a friction between the teeth and the hair of the pet.

Abstract: The present invention provides methods of producing recombinant cells, methods of large scale production of a gene expression product (such as protein), and methods of establishing a stable cell line using the surface markers. Also provided are expression vectors encoding the surface markers and cells comprising the expression vectors. Further provided are gene expression products (such as proteins) and cells obtained using methods described herein, as well as kits useful for carrying out methods described herein.

Abstract: A squirrel proof bird feeder includes a hanger device, a bird feeder container attached to the hanger device, and a shield attached to the hanger device and located above the bird feeder container, and the shield includes two shielding members each having one or more latching members, and the latching members of the shielding members are engageable with each other for securing the shielding members together and for attaching the shield to the hanger device directly without disassembling or disengaging the hanger device or the bird feeder container from the hanging cable. The shield includes an opening for engaging with the hanger device, and the latching members are selected from a lock tab, or a latch.

Abstract: A portable electronic device comprises a cover, a base and a sliding mechanism. The sliding mechanism includes a connecting rod mechanism and a controlling mechanism. The connecting rod mechanism is rotatably mounted between the base and the cover and is configured to rotate the cover relative to the base. The controlling mechanism is configured to control the rotation of the connecting rod mechanism.

Abstract: A battery cover which detachably mounted on a portable electronic device to protect the battery of the portable electronic device. The battery cover includes a main cover and a sliding cover, the sliding cover is slidably mounted on the main cover. Two opposite ends of the main cover and the sliding cover each includes at least one tab or projection protruding there from respectively. The battery cover has a simple structure, and is easy for operating. The invention also includes a portable electronic device using the battery cover.

Abstract: A rotary mechanism includes a base (10), a cover (30), a torsion spring (40) and a locking module (20). The rotary cover is rotatably mounted to the base. Two ends of the torsion spring are fixed with the base and the cover, respectively. The locking module limits the cover from rotating relative to the base. When the cover overcomes the limitation of the locking module, the cover can automatically rotate relative to the base due to the torsion spring.

Abstract: A bone shaped pet product includes a longitudinal food member and a longitudinal rope member tied together to form two knots and to form a bone shaped structure, the longitudinal food member is made of cattle hide material or other food materials, and the longitudinal rope member is made of fiber materials, such as cotton fibers and includes two or more strands of fiber or thread materials. The longitudinal food member and the longitudinal rope member may be twisted together to form a further solid and stable structure.

Abstract: A portable communication device includes a housing body and a display. The housing body includes a hinge portion at one side. A block is formed at each side of the hinge portion. A display forms two knuckles at the other end. Each knuckle forms a plurality of teeth portions, and the hinge portion rotatably connects to the two knuckles. The blocks engage with the teeth portions allowing the display to hold any of a variety of selectable positions relative to the housing body.

Abstract: A hinge assembly includes a positioning module, a connecting module and a rotating module. The positioning module includes a sleeve. The connecting module includes a pivot tube and a shaft. The pivot tube is rotatably attached to the sleeve. The shaft is slidably and rotatably received in the pivot tube. The rotating module is rotatably attached to one end of the shaft.

Abstract: A portable electronic device comprises a housing and a chip card ejecting mechanism. The housing has a mounting portion defined therein. The ejecting mechanism includes a holder and a controlling module. The holder is slidably accommodated in the mounting portion of the housing. The controlling module includes a button and an ejecting element. The button releasably secures with the holder in the mounting portion. The ejecting element resistes against the holder to provide an elastic force for driving the holder slid. When the button is pressed, the holder is released and the ejecting element ejects the holder outwardly from the mounted portion of the housing.
