There is provided a device for fastening a connecting member to a handle of a cooking vessel; the connecting member has a collar portion having an inner cavity into which a connecting portion of the handle is inserted; the collar portion is bounded by a lateral wall closed into a loop by means of two opposite end tabs joined to each other and defining at least one preassembly tooth cooperating with a seat formed in the connecting portion; and the connecting member has a fastening member, which is pressed and permanently deformed inside a recess on the connecting portion to secure the connecting portion inside the cavity.

A shank for a large-size umbrella includes a base tube, a rotation tube, a plurality of rotation balls, and a rotation control member. When the rotation balls are rotated to a determined position, the limit post of the contact face of the rotation tube is rotated into and limited in the limit hole of the rotation control member so as to limit rotation of the rotation tube. Thus, the rotation of the rotation tube is limited by the rotation control member so that the rotation tube will not be rotated excessively, thereby preventing the control cord from being tangled.

An apparatus for supporting a load comprises a pivot apparatus coupled to the load and movable with the load; and a base stationary relative to the pivot apparatus. At least two areas of support are situated between the pivot apparatus and the base. Respectively opposite force components are at the two areas of support. The two areas of support move along a one curved path to tilt the load.

A connecting device includes an inner component (100) and an outer component (200). The inner component is dimensioned to be at least partially received in the outer component, with a pair of surfaces (102A, 102B) of the inner component facing a pair of corresponding surfaces (202A, 202B) of the outer component. At least some of the surfaces include interengageable formations (106, 108, 206, 208). The device further includes an arrangement (104) for allowing relative movement between at least one of the surfaces of the inner component and the corresponding surface of the outer component to allow for engagement and/or disengagement of the formations.

A joint for use in electrochemical devices, such as solid oxide fuel cells (SOFCs), oxygen separators, and hydrogen separators, that will maintain a hermetic seal at operating temperatures of greater than 600° C., despite repeated thermal cycling excess of 600° C. in a hostile operating environment where one side of the joint is continuously exposed to an oxidizing atmosphere and the other side is continuously exposed to a wet reducing gas. The joint is formed of a metal part, a ceramic part, and a flexible gasket. The flexible gasket is metal, but is thinner and more flexible than the metal part. As the joint is heated and cooled, the flexible gasket is configured to flex in response to changes in the relative size of the metal part and the ceramic part brought about by differences in the coefficient of thermal expansion of the metal part and the ceramic part, such that substantially all of the tension created by the differences in the expansion and contraction of the ceramic and metal parts is absorbed and dissipated by flexing the flexible gasket.

An extension pole suitable for use in light bulb changing operations. The extension pole comprises first, second, and third telescopically intercoupled sections. A first locking assembly selectively locks the first and second sections to one another, and a second locking assembly selectively locks the second and third section to one another. The extension pole is made entirely of non-conductive materials to thereby reduce the risk of electrical shock to the operator.

A foldable frame includes spaced-apart first and second support rods, a first bar having a first end connected pivotally to the first support rod, a second bar having first and second ends connected pivotally and respectively to the second support rod and a second end of the first bar, a sleeve disposed slidably around the first bar and movable to a juncture of the first and second bars when the bars are unfolded so as to limit relative movement between the first and second bars, and a control unit having a cable connected to the sleeve for pulling the sleeve away from the juncture of the first and second bars so that the first and second bars can be folded.

Telescoping tubes can have holes distributed in the pattern of a vernier caliper, thereby providing an easy means of locking the tubes in a desired length. Similarly, plates can have holes distributed in two dimensions in the pattern of a vernier caliper's, thereby providing a means of accurately locking size in two dimensions.

An end securing device for a telescopic tube includes a vacuum sucker made up of a suction cup, a retaining piece, a control piece, and an activation piece to be mounted to both ends of a telescopic tube thereof respectively wherein the suction cup has a driven post protruding at one side of a conic suction space to be engaged with the retaining piece thereby, and the retaining piece has a registration column and a central through hole in sleeve engagement with a coupling groove of the control piece. The driven post of the suction cup led through an engaging through hole of the control piece is securely screwed up to a linkage rod of the activation piece thereof. In operation, the control piece is rotated to one side via a push block, permitting oblique conic sliding guide plates of the control piece to ascend along stop ribs of the retaining piece till the control piece abuts tight against the activation piece so as to move the driven post thereof and raise upwards the suction cup therewith to form an empty vacuum space at the suction space therein for secure attachment of the suction cup to the surface of walls thereon. Otherwise, the control piece is rotated to the other side to descend the sliding guide plates thereof so as to release the activation piece and the suction cup therewith for air to let in to the suction space thereof to detach the suction cup thereof. Thus, the telescopic tube is easily and quickly adjusted in length by direct stretching or pushing without a spring unit applied therein and securely mounted onto the walls via the vacuum suckers thereof.
