Insulating material

A composite insulating material which is comprised of one or more layers of open ended cells formed from flexible thin plastic sheet, and may be fastened to one or more cover sheets. The material is flexible enough to be worn as clothing and derives its insulating properties by reducing thermal conducting paths and areas, by introducing numerous controlled geometry air cells between the heat source and inner layer to further lower conductivity and inhibit convection currents and, by absorbing radiant thermal energy within the cell walls thereby reducing heat transmission by radiation. Metallized reflecting layers are not required to achieve high insulating efficiency.

Two-step composite joint

The two-step composite joint has improved strength to withstand both axial and bending loads and comprises two articles (3;6) each comprising a filler layer (15; 30) disposed between first and second composite layers (12,18;24,27). An end section (39) of the first article's first composite layer (12) is disposed external to, overlapping and bonded to an end section (42) of the second article's first composite layer (24) to form a first overlap (45). An end section (54) of the second article's second composite layer (27) is disposed inter­nal to, overlapping and bonded to an end section (51) of the first article's second composite layer (18) to form a second overlap (57). The first overlap (45) is displa­ced across the thickness and along the length of the joint (9) from the second overlap (57). Loads are trans­ferred across the joint (9) from first layer (12) to first layer (24) and from second layer (18) to second layer (27).

Truss core panels

Truss core panels comprising face sheets and a core, formed of adjoining tubes having an equilateral triangular cross-sectional shape, are disclosed. The face sheets are formed of either a homogeneous material (e.g., a metal, such as aluminum or titanium); or, a composite material, such as a laminate formed of bonded plies. The plies are woven from suitably strong fibers (e.g., glass or graphite), bonded together by a suitable resin. The tubes are also formed of either a homogeneous material or laminated from suitably strong fibers bonded together by a resin. Depending upon the material used, the tubes can be either formed by pultrusion or by machine winding on mandrels and cured. The tubes may be formed of the same material as the face sheets or different materials. Stiffening ribs and the like are formed by including additional layers of tubes. Further, the tubes may be filled continuously or intermittently, as desired, to accommodate fasteners. Since the tubes are equilateral triangles in cross-sectional shape, assembly of the tubes in one or more layers is fast and, therefore, inexpensive.

First and second webs (1, 2) sheet material are superimposed on each other and fed in the longitudinal direction. Plastic film is cut along longitudinal cutting lines (13) and (14) to separate it on first sheet (1) of sheet material and several sheets of material of lower insert (3, 4) before folding sheets (1, 2) of sheet material. Then web material of lower insert (3, 4) are sent and fed to first or second canvas (1) or (2) sheet material through device (21, 28) material direction of the lower insert. Plastic bags are made in pairs. Installation for continuous manufacture of plastic bags includes a device for feeding sheet material and cutting devices for cutting the corresponding web into several parts along its longitudinal axis and feeding individual webs to form bags.EFFECT: technical result achieved when using the group of inventions consists in ensuring continuous manufacturing of plastic bags, excluding the feeding of the bottom insert from another feed roller and the avoidance of misalignment of patterns.4 cl, 11 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (51) МПК B31B 50/04 B29C 69/02 B29D 24/00 B31B 70/10 B31B 70/18 (11) (13) 2 670 862 C9 (2017.01) (2006.01) (2006.01) (2017.01) (2017.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) СКОРРЕКТИРОВАННОЕ ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ Примечание: библиография отражает состояние при переиздании (52) СПК B31B 50/10 (2018.08); B31B 50/18 (2018.08); B29C 69/02 (2018.08); B29D 24/00 (2018.08) (21)(22) Заявка: 2018100189, 09.06.2016 09.06.2016 (73) Патентообладатель(и): ТОТАНИ КОРПОРЕЙШН (JP) Приоритет(ы): (30) Конвенционный приоритет: 20110039676 A1, 17.02.2011.

A method for manufacturing composite storage tank of great guantity

본 발명은 오수정화, 산업용 폐수처리, 간이 정수등과 같은 여러단계의 연속적 처리과정을 거치는 대용량의 저장탱크 및 각종 저장물을 하나의 탱크에 각각 분리하여 저장할 수 있는 복합형의 대형 저장탱크의 제조방법에 관한 것으로서, 탱크의 본체(1)를 열가소성 합성수지 재질의 대구경 플라스틱 파이프로하고 외부경판(2)(2')을 비롯한,내부격판(3)(3')(3")..과 기타 부재도 상기 대구경 파이프와 동일재질의 두꺼운 플라스틱으로 제작하여 상기 본체(1)에 상기 부재들을 적정위치에 수직으로 놓고 그 수직으로 맞닿는 접촉 부위를 용융온도이상의 열풍으로 가열하면서 상기 대구경 파이프 본체 및 부재와 동일재질의 열가소성 합성수지를 소형 압출장치로 압출 가압하는 방법으로 필릿 용접(fillet welding)을 하거나, 상기 서로 맞닿는 접촉부위의 사이에 가열철판을 끼우고 가열하여 양쪽 접촉부위를 가열용융시킨 후 가열 철판을 제거함과 동시에 맞닿는 부위를 용접하는 방법으로 맞대기 용접(butt welding)을 하거나, 상기 맞닿는 부분을 맞대기 용접후 상기한 필릿 용접하는 이중 용접방법으로 용접하여 대구경의 복합저장탱크를 제조하므로써 제조가 간편용이하고 제품의 외관이 미려하고 견고하여 저렴하게 지하매설용 등으로 사용할 수 있는 장점이 있는 것이다. The present invention provides a large-capacity storage tank that can separate and store large-capacity storage tanks and various types of storage in a single tank, each of which undergoes a series of continuous processes such as sewage purification, industrial wastewater treatment, and simple water purification. Method, wherein the body of the tank (1) is made of a large diameter plastic pipe made of thermoplastic synthetic resin, and includes an outer plate (2) (2 '), an inner plate (3) (3') (3 "), and the like. The member is made of thick plastic of the same material as the large diameter pipe, and the members are placed vertically on the main body 1 at a proper position, and the contact portions which abut the vertical diameters are heated with hot air above the melting temperature, and Fillet welding is performed by extruding a thermoplastic resin of the same material by using a compact extrusion device, or is applied between the contacting portions which are in contact with each other. Insert and heat the hot iron plate to heat and melt both contact areas, and then remove the heated iron plate and weld butt welds at the same time. By manufacturing a large diameter composite storage tank by welding by welding method, it is easy to manufacture, and the appearance of the product is beautiful and robust, ...
