A body-supporting device includes a tray, a net and a frame. The tray includes a margin and a groove in the margin. The groove gets narrower downwardly. The net includes a margin. The frame includes a first rib for inserting the margin of the net into the groove of the tray and a second rib for pressing the margin of the net against the margin of the tray. The first rib gets narrower downwardly. Fasteners are driven into the first rib of the frame through the margin of the tray. The sandwiching of the margin of the net between the first rib of the frame and the margin of the tray gets firmer as the fasteners get tighter in the first rib of the frame.

In an organ retractor including a shaft defining a longitudinal axis and a longitudinal plane, and at least one organ support assembly operatively coupled to the shaft. The organ support assembly includes a plurality of ribs having a first position, in which each of the plurality of ribs is parallel with one another, and a second position, in which a first rib of the plurality of ribs is transverse with respect to a second rib of the plurality of ribs. The at least one organ support assembly is pivotable from a first orientation, in which each of the plurality of ribs is disposed in the longitudinal plane of the shaft, to a second orientation, in which each of the plurality of ribs is disposed at an angle relative to the longitudinal plane of the shaft, and a support extending between and connected to each of the plurality of two ribs.

An orthopaedic device to realign bone segments comprises first and second attachment members and a spacer member. The first attachment member is attached to a first rib bone or first transverse process of a vertebra. The second attachment member is attached to a second rib bone or second transverse process of a vertebra adjacent to the first rib bone or the first transverse process. The spacer member is positioned between the first and second attachment members. The spacer member provides distraction between the first and second rib bones or transverse processes to realign the rib bones. The spacer member is releasably connected to the first and second attachment members. The attachment members comprise a clamp and screw combination.

A collapsible core device for molding articles around the core device in a mold cavity includes a first sleeve, a second sleeve and an expansion member. The first sleeve includes a plurality of first ribs extending from a first base in an axial direction and defining a discontinuous first perimeter surrounding a channel. The second sleeve includes a plurality of second ribs extending from a second base in an axial direction and defining a discontinuous second perimeter surrounding the central channel. Each of the second ribs is arranged between adjacent ones of the first ribs. The expansion member is fittable within the central channel to displace the first and second ribs outwardly to form an overall perimeter defined by the first and second ribs.

A plumbing support bracket for supporting plumbing pipes between structural members comprises a pair of end tabs and a center section between the end tabs. The end tabs are bendable relative to the center section. The center section has opposed first and second edges with a plurality of pipe receiving notches formed in the first edge. The center section further includes a row of longitudinally spaced pipe receiving holes. The center section is made more rigid than the end tabs by first and second ribs. The first rib comprises a flange formed along the second edge of the bracket and the second rib comprises an elongate longitudinal bulge formed in the body between the bases of the pipe receiving notches and the row of pipe receiving holes.

A heat exchanger includes a corrugated metal sheet comprising a first side having a plurality of first troughs alternating with a plurality of first peaks, and a second side having a plurality of second troughs alternating with a plurality of second peaks, each trough being formed by a pair of walls, each wall separating the first side from the second side and extending from a first peak to a second peak, the troughs and peaks extending in parallel and defining a longitudinal direction. Each first peak is formed with at least one depression, the depressions in respective peaks being aligned to form at least one tube-receiving channel extending transversely to the longitudinal direction. Each depression has a contact surface formed in the first side and extending laterally over each adjacent first trough. A tube section is received in each tube-receiving channel in substantially conforming contact with the contact surfaces. The heat exchanger is manufactured using first and second fixtures having first and second sets of parallel ribs which are received in respective second and first troughs of the corrugated sheet. The first peaks are formed downward using a mandrel received through windows interrupting the second ribs, the depressions being formed in corresponding notches in the first ribs.

Various embodiments of the present invention are directed to a movement control screed that is structured for installation between first and second masonry coatings applied adjacent to a building wall. The movement control screed is structured as a control joint for absorbing movement between the first and second masonry coatings and also as a weep screed for accommodating drainage of water from behind the masonry coatings. The movement control screed comprises first and second flanges provided on opposite sides of first and second ribs.

An orthopaedic device to realign bone segments comprises first and second attachment members and a strut or spacer member. The first attachment member is attached to a first rib bone or first transverse process or first lamina of a vertebra. The second attachment member is attached to a second rib bone or second transverse process or second lamina of a vertebra. The strut is positioned between the first and second attachment members. The strut is fixedly or releasably connected to the first and second attachment members to couple the first attachment member to the second attachment member. The strut provides distraction between the first and second rib bones or transverse processes to realign the rib bones. The attachment members comprise a clamp and screw combination.

Methods and apparatus for cooling gas turbine rotor blades is provided. The rotor blades include an airfoil having a pressure sidewall and a second suction sidewall connected together at a leading edge and a trailing edge, such that an internal three pass serpentine cooling circuit is formed therebetween. The cooling circuit includes radially extending first, second, and third serpentine cooling cavities partially separated by, in axially aft succession, a first radially extending internal rib and a second internal rib. The second rib includes a radially inner first portion and a radially outer portion wherein the radially outer portion is angled obliquely with respect to the first portion.

A hydraulic antivibration device capable of sufficiently reducing strange sounds is provided. The one in a first embodiment includes first ribs whose tops are spaced apart from lattice members and second ribs having tops abutting on the lattice members and a smaller rib width than the first ribs. When an elastic partition membrane impinges on the lattice members with vibration, the second ribs resist and the elastic partition membrane impinges moderately on the lattice members, so that strange sounds can be reduced. In a second embodiment, such first and second displacement-regulating protrusions are provided that are disposed asymmetrically relative to a phantom plane passing through a center of the elastic partition membrane in its thickness direction. When the elastic partition membrane is displaced, the displacement-regulating protrusions on the opposite side to the displacement direction intensify the stiffness of it locally, so that the elastic partition membrane is difficult to displace, leading to an effective reduction of strange sounds.
