The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to valve configurations providing sealable access for medical instruments to a working channel, such as a working channel for an endoscope.

A reusable countertop mold in accordance with the present invention includes a bracket member detachably secured to a rail portion of a cabinet member for a substantially horizontal substrate that receives deformable material upon a surface of the substrate. The bracket member includes vertical, horizontal and channel members integrally joined together for enabling a channel member to removably receive the rail member. The mold further includes a locking bolt for detachably securing the bracket member to the rail portion of the support member. A form member is detachably secured to the bracket member, the form member continuously extending outside the perimeter of the substrate and receives deformable material that ultimately solidifies; whereby, the substrate surface and the form member cooperate to configure a countertop that continuously extends upon and outside the perimeter of the substrate, thereby forming a countertop having an integrally joined overhang portion; whereupon, the reusable countertop mold is removed from the solidified countertop overhang portion and the rail portion.

A method for creating a honeycomb core having venting pathways includes controlling where a resin is applied to sheets to form the venting pathways. A honeycomb substrate is then formed from the sheets.

Hinged container cap, comprising a base portion, a hinge member and a lid, wherein the base portion is made of a crystallisable polymer and includes a base circumferential wall and a base containment wall having an base outlet aperture and has an external base surfaceexternal base surface 44, wherein the hinge member connects the base portion to the lid and allows a movement of the lid between an opened position, in which the base outlet aperture is open, and a closed position, in which the base outlet aperture is closed, wherein in the closed position, at least part of the external base surfaceexternal base surface 44 of the base portion forms an interface with the lid contact surfacelid contact surface 42 of the lid, wherein the base portion and/or of the lid wall is crystallized at at least the interface of the base portion and the lid in the closed position, to allow the lid to be opened after being closed for an elongated period.

Provided is a turbine blade, including shells and webs connected to the shells, with, with each web being supported by reinforcement structures, whereby a first reinforcement structures includes at least one stack composed of several pultruded composite strips including carbon fibers with the strips being fixed in a resin matrix, and a second reinforcement structures supporting a second web either include at least one stack composed of glass and/or carbon fiber layers infused with resin, the stack being disposed between an outer and an inner layer of upper and lower shell, or at least one stack composed of glass and/or carbon fiber layers infused with resin or of several pultruded composite strips including carbon fibers with the strips being fixed in a resin matrix, which stack is an integral part of the second web and builds the flange.

Provided is a wind turbine blade, with a generally hollow blade body including half shells and webs the webs including flanges connecting the respective web to the respective half shell, and with webs being supported via reinforcement structures relative to the respective half shell, which reinforcement structures are arranged between an outer and an inner layer of each half shell and extend in the lengthwise direction of the blade, whereby the reinforcement structures each include at least one stack composed of several glass fiber layers infused with resin, and that at least one stiffening element extending parallel to the first and second reinforcement structures over at least a part of their length including at least one stack composed of several pultruded composite strips including carbon fibers with the strips being fixed in the resin is arranged between the first and second reinforcement structures.

Provided is a turbine blade, with a first and a second elongated web connected to an upper and a lower half shell, with each web including an upper and a lower flange connecting the respective web to the respective half shell, and with the first and second webs being supported by respective first and second reinforcement structures, which reinforcement structures extend in the lengthwise direction of the blade, wherein each first and second reinforcement structure supporting the first and second web includes at least one stack composed of several pultruded composite strips including carbon fibers with the strips being fixed in a resin matrix, wherein each at least one stack composed of the pultruded composite strips is an integral part of the respective first and second web and builds the respective flange, which is attached to the inner layer of the respective upper and lower shell.

A method of forming a composite component comprising a layer which consists at least partly of polyethylene, a layer which consists at least partly of a polyurethane and/or an elastomer, at least one layer which consists at least partly of a plastic reinforced by fibers, or which consists at least partly of an adhesive, wherein the layer is disposed directly between the layer and the layer, wherein the layers have been joined in a first operation to form a laminate composite and the layer have been joined in a second operation onto the laminate composite comprising the layers.

This composite material blade, which is formed using a composite material including reinforcing fibers and resin, and which has a positive pressure surface and a negative pressure surface, is provided with a ventral part, being the part on the positive pressure surface side in a blade thickness direction, which is the direction joining the positive pressure surface and the negative pressure surface, a dorsal part, being the part on the negative pressure surface side in the blade thickness direction, and a metal shield portion which is provided on the leading edge side, being the upstream side in a flow direction in which a fluid flows, wherein: the metal shield portion includes a main body portion provided on the leading edge side, and an embedded portion which is provided on the trailing edge side, being the downstream side in the flow direction, of the main body portion, and which is provided between the ventral part and the dorsal part; and the plate thickness of the metal shield portion in the blade thickness direction decreases from the main body portion toward the embedded portion.

A method of manufacturing a wind turbine blade body, the method comprising the steps of: providing a mould (40) having a mould surface (43) for forming a first blade body having a first length, the mould having a mould root end and a mould tip end (42); placing a removable insert (50) on the mould surface towards the mould tip end to form a modified mould surface for forming a second blade body having a second length which is less than the first length; and forming the second blade body on the modified mould surface.
