A panel turning apparatus which turns a panel from a first orientation to a second, desired orientation. The apparatus has a rotatable portion rotatable about an axis of rotation thereof, and a base portion which supports the rotatable portion for rotation about the axis of rotation. The rotatable portion has a panel carrying portion aligned with the axis of rotation, a supported portion which supports the rotatable member for rotation and a driving portion by which the rotatable member is rotated to carry a panel carried by the panel carrying portion from the first orientation to the second, desired orientation. The apparatus permits a panel, even a large and heavy panel, to be turned safely and easily by one person.

A rubber hose material for providing a rubber hose excellent in mechanical strength and with an intrinsic property (elongation) of rubber retained. The rubber hose material is formed by blending an ethylene-olefin resin (component (B)) as an organic filler into an ethylene-propylene rubber (component (A)).

A metal cutting tool assembly comprising a rigid holder blade, an insert receiving slot formed in a leading end of the holder blade and defined between a resiliently displaceable clamping jaw formed integrally with the holder blade and rigid base jaw forming part of the holder blade, spaced apart displacement and supporting surfaces respectively formed in or on the clamping jaw and the holder, and a slot opening key, a pair of spaced apart projecting prongs of the key with adapted to engage the surfaces. At least one of the prongs is displaceable with respect to the holder blade so as resiliently to displace the clamping jaw outwardly with respect to the base jaw into an opening position for insertion or removal of an insert.

A fluid treatment unit and a sealing structure which is preferably for the fluid treatment unit are provided. The sealing structure includes: a cylinder with an opening formed at one end thereof, the cylinder comprising an inner wall surface and an outer wall surface, and an outer thread being provided on the outer wall surface; a sealing cover which is capable of hermetically cooperating with the inner wall surface of the cylinder to seal the opening; a support cover which is capable of being connected with the cylinder by thread engagement; when the support cover and the cylinder are relatively rotated in order to achieve a threaded connection of the support cover and the cylinder, the support cover is capable of supporting the sealing cover and impelling it to move in parallel so as to allow the sealing cover to reach a position at which it seals the opening.

The invention discloses a placing rack for glass transport. The placing rack comprises a fixed baseplate, wherein a supporting vertical plate is mounted on one side of the fixed baseplate; a guiding mechanism is arranged at the upper end of the fixed baseplate; three height adjusting grooves penetrate the surface of the supporting vertical plate; a height adjusting lead screw is mounted in one ofthe height adjusting grooves; guiding shafts are mounted in the other two height adjusting grooves; lifting blocks are mounted on the height adjusting lead screw and the guiding shafts; a lifting plate is mounted at the end parts of the lifting blocks; and a fixing mechanism is arranged at the bottom of the lifting plate. The placing rack has the following beneficial effects: glass can be separately placed through the guiding mechanism and the fixing mechanism, and therefore, is prevented from direct contact which leads to surface abrasion; a slide bar slides in a slide cavity by means of an elastic force of a compression spring, so that a compression block compresses the glass and the glass is fixed; and the height adjusting lead screw is rotated to enable the lifting blocks to drive thelifting plate to ascend and descend, so that the height of the lifting plate is adjusted, and the requirement for placing glass of different sizes is satisfied.

The invention discloses a side bending mold for a back plate. The side bending mold for the back plate comprises an upper mold plate and a lower mold plate, wherein the upper mold plate is provided with a guide sleeve; the lower mold plate is provided with a guide column; the guide column can move up and down in the guide sleeve; a return spring is arranged in the guide sleeve; the upper mold plate is connected with a male mold; a first roller is arranged at each of the two ends of the lower end surface of the male mold; the lower mold plate is connected with a female mold; a second roller is arranged at each of the two ends of the upper end surface of the female mold; stop blocks used for positioning a workpiece are arranged at the parts, positioned on the two sides of the female mold, of the lower mold plate. During mold closing, the upper mold plate moves down relative to the lower mold plate, the workpiece between the two stop blocks is bent downwards, and after the workpiece is bent, the upper mold plate moves up and returns under the action of the return spring. The side bending mold for the back plate is simple in structure and convenient to operate, the surface abrasion caused by sliding of the workpiece at the corner is avoided, and the bending quality of the workpiece is guaranteed. The side bending mold for the back plate is simple in structure and convenient to operate; moreover, the surface abrasion caused by bending of the workpiece can be avoided, and the bending quality of the workpiece is improved.

The invention relates to an adjustable camshaft (1) for the valve train of an internal combustion engine, having an outer shaft (10) and an inner shaft (11) extending concentrically with the outer shaft (10) and rotatably accommodated therein, wherein on the outer surface (13) of the outer shaft (10), at least one cam member (12) is rotatably mounted while forming a slide bearing gap, wherein the cam member (12) is connected to the inner shaft (11) in a rotationally fixedly manner. According to the invention, in the outer surface (13) of the outer shaft (10), at least one oil routing groove (14) is introduced in a position and with an axial length such that the oil routing groove (14) is formed at least across the axial width of the slide bearing gap, and that on at least one side of the cam member (12), the oil routing groove is brought out from the slide bearing gap with a free groove portion (15).
