Embodiments described herein are directed to methods of manufacturing a multi-leaf membrane module for filtering product fluid flow (e.g., food products or wastewater) and such multi-leaf membrane modules. In an embodiment, a multi-leaf membrane module is disclosed. The multi-leaf membrane module includes a permeate fluid flow tube defining a permeate fluid flow channel for permeate, and a membrane sheet spirally wound about the permeate fluid flow tube. The membrane sheet includes two or more leaves. Each of the two or more leaves includes a feed spacer including at least one opening formed therein that at least partially defines a feed channel for product fluid flow therethrough and a permeate structure defining a permeate fluid flow channel. The permeate structure of each of the two or more leaves includes at least one membrane and at least one porous permeate spacer.

A treadmill having a curved treadmill deck is provided. Two curved side frames are disposed at two sides of the treadmill frame. Front and rear end ends of each curved side frame are higher than a middle section thereof. Inner sides of the two curved side frames are provided with a plurality of fixing seats, respectively. The fixing seats have fixing holes, respectively. An elastic deck is composed of a plurality of sheets connected side by side. The sheets each have perforations corresponding in position to the fixing holes of the respective fixing seats. A plurality of fixing pins are inserted in the perforations of the sheets of the elastic deck and secured to the fixing holes of the fixing seats. The elastic deck is forcibly fastened by the fixing pins and slightly deformed according to the curvature of the curved side frames to form the curved treadmill deck.

This disclosure describes methods and devices useful for adhering a first substrate of a display to a second substrate of the display. In example embodiments, a first plate may be sealed to the first substrate, and a second plate may be sealed to the second substrate. In addition, a layer of adhesive may be disposed between the first and second substrates to assist in adhering the first substrate to the second substrate. A pressure may then be applied to the first and second plates as well as the first and second substrates to assist in the adhesion process. In example embodiments, the first plate may assist in applying pressure proximate a perimeter of the first substrate such that the perimeter of the first substrate adheres to a perimeter of the second substrate.

A material composition including a matrix including a first material, the matrix including a plurality of voids disposed in the matrix, two or more voids being spaced apart from each other, a plurality of elongate fibers of a second material located within the matrix, wherein the plurality of fibers are configured to reinforce the matrix and, wherein the material composition is a composite material composition.

In order to provide a composite good in formability into a three-dimensional shape and easy to manufacture, in a laminate having a core material layer and a skin material laminated on the core material layer, the core material layer has a plurality of plate-shaped flakes lined up along a surface of the skin material, and adjacent plate-shaped flakes are separated from each other by a gap or by a cut in the core material layer, and cutting directions along a thickness direction, which is determined from cutting marks formed on an outer periphery, are identical to each other among the plurality of the plate-shaped flakes.

In order to provide a new and improved bonding arrangement, especially for use in an aircraft or spacecraft, which is designed to overcome problems of bonding arrangements under Mode I loading stress and which is designed or configured particularly to create a bond design which is incapable of locally loading the adhesive bond above the peel strength, a bonding arrangement is disclosed with a coating structure, which is split into a plurality of neighboring structural elements spatially separated from each other, and at least one supporting member is provided, which comprises a plurality of recesses receiving the structural elements in operating position.

Cushioning elements include a breathable material configured to allow gases to pass through at least a portion thereof, and a plurality of discrete segments of thermoplastic elastomeric gel (gel) heat-fused or otherwise attached to the breathable material. The gel comprises an elastomeric polymer and a plasticizer, with a plasticizer-to-polymer ratio of from about 0.3 to about 50. The plurality of discrete segments defines at least one breathable gap between adjacent discrete segments. Methods of forming cushioning elements include forming a plurality of discrete segments of gel, securing each segment to a breathable material, and providing a gas path through the breathable material and between adjacent segments. Another method includes providing molten gel within a mold, providing at least a second portion of the gel within a permeable material, and solidifying the gel to form discrete segments of gel.

A decorative sheet includes a first surface and a second surface positioned opposite to the first surface. The first surface includes a first region and a second region that is different from the first region. The decorative sheet includes a surface protective layer, a design layer, and a substrate in order from the first surface toward the second surface. The design layer includes a patterned portion disposed only in a location that overlaps the first region. An average skewness Ssk1 of the first region and the average skewness Ssk2 of the second region satisfy a relationship (i), shown below. An average kurtosis Sku1 of the first region A1 and an average kurtosis Sku2 of the second region satisfy a relationship (ii), shown below

[00001]$\begin{array}{cc}0<\mathrm{Ssk}2<\mathrm{Ssk}1<1& \left(i\right)\end{array}$$\begin{array}{cc}3<\mathrm{Sk}\mathrm{u2}<\mathrm{Sku}1<5.& \left(\mathrm{ii}\right)\end{array}$

A double-sidedly self-adhesive planar element which is intrinsically heatable in a self-regulating way and at the same time has a particularly high flexibility. The planar element has a layer sequence of a posistor heating layer, a contacting layer and an adhesive layer, the contacting layer being a two-dimensional perforate contacting element which within the planar element is therefore present as a contacting element which has not been applied to a backing. Also disclosed is an adhesively bonded assembly of a bonding substrate and a planar element of the aforesaid kind, a method of producing a planar element of the aforesaid kind, and a method of using a planar element of the aforesaid kind for heating an adhesively bonded assembly.
