A removable toaster basket assembly to be removably received in a toasting slot of an electric pop-up toaster facilitates inserting and removing food articles in the toasting slot for toasting of the food article. The removable toaster basket assembly includes an elongate substantially planar frame for resting on an upper surface of the toaster and defines a rectangular slot therethrough. A handle extends from one end of the frame. An elongate basket is slidably received in the slot, the basket having ends and sides which define an open top for receiving a food article. A stop on the basket limits translation of the basket with respect to said frame to maintain the basket captive within the frame.

An embodiment of a running tool for setting and testing a packoff seal of a well pipe hanger has an elongated stem having an axial passage, a body, a cam, a cam tail, a stem engagement element, and a piston. A method of setting and testing a packoff seal comprises rotating the stem relative to the body to a delivery position, thereby disengaging the engaging element from the stem. The stem moves axially downward relative to the body to land the packoff. The engagement element reengages the stem in a landing position. Fluid pressure is applied to the axial passage to set and seal the packoff, thereby moving the running tool to a set position.

A structure for mounting a fuel cell stack in an enclosure or a frame includes a first mounting mechanism for fastening and mounting a first mounting part located at a first side of the fuel cell stack in a longitudinal direction of the stack, which is a cell stacking direction, to the enclosure or the frame in a completely fixing fashion, and a second mounting mechanism for mounting a second mounting part located at a second side of the fuel cell stack in the longitudinal direction of the stack to the enclosure or the frame in a state of being movable in the longitudinal direction of the stack.

A deployment apparatus for a flexible cover sized to cover a side-dump container comprises first and second swing arm assemblies pivotally mounted at a pivot point to opposite sides of the container. A drive assembly connected to the roll tube of the flexible cover is operable to rotate the roll tube so that the flexible cover winds around the roll tube. The drive assembly is slidably supported on one of the swing arms so that the mechanism translates along the length of the swing arm as it winds the flexible cover around the roll tube. A stop is provided on the swing arm between the pivot point and the free end to limit the translation of the drive assembly along swing arm. In another form, the drive assembly is fixed to a swing arm that is slidably received in a pivoting spring mechanism.

A grip of space robot is disclosed, which features wide capture range and high locating precision. The motor position sensor is fixed to motor driver connected to supporting sleeve fixed to harmonic speed reducer installed to mainshaft of motor and connected with drive flange. Said drive flange is fixed to shaft-end flange connected with finger position sensors. The gear drive unit on drive flange is connected respectively with the single-finger and dual-finger 4-connection-rod units. The contact sensor is arranged in V-shaped slot on shell.

A lockout system that limits use of a rolled web material dispenser assembly to dispense only authorized rolls of web material. The lockout system includes a hub and an insert that cooperate with one another to define mating registration elements that removeably cooperate with one another and provide a rotational cooperation therebetween when engaged with one another. The insert is shaped to be received in a bore of discrete authorized roll of web material. In one embodiment, the insert includes an overlapping portion formed between opposing ends of the insert and preferably between rotational bearing surfaces associated therewith. In another embodiment, the hub supported by the dispenser is moveable relative to the dispenser and renders the hub unavailable for operative cooperation with inserts that are not configured for cooperation therewith.

The invention discloses a method for installing a curved steel reticulated shell structure with a gable starting span gradually changing, comprising the following steps: a. construction preparation; b. assembling block by block; c. installing a purlin system and a roof panel structure. The invention realizes the connection between the steel wire rope and the ball joint through the steel wire rope pulling device, ensures the stability of the steel wire rope pulling and setting, prevents the steel wire rope from sliding, ensures the verticality of the vertical gable structure, and avoids the rods of the reticulated shell structure during the steel wire rope pulling. At the same time, in the present invention, the ball joints inside the gable reticulated shell unit are supported by the temporary fixing device to increase the construction safety performance, and the temporary fixing device can also eliminate the influence of the site flatness error on the installation accuracy, which is more conducive to the ball joints The installation and construction between temporary fixtures are convenient for construction and operation, flexible and convenient for on-site construction, easy to adjust accuracy errors, high construction efficiency, guaranteed installation quality, reduced safety hazards for high-altitude operations, and reduced construction costs.
