Method and apparatus for tissue excision and removal by fluid jet

A method and apparatus for the excision and removal of tissue, such as the lens of the eye includes a pencil-like handpiece having a cannula probe extending from the distal end thereof. The probe includes an inner jet tube to direct a high pressure jet of fluid toward a tissue target, and an outer concentric aspiration tube to aspirate and remove fluid and tissue. The jet tube is recessed proximally within the concentric aspiration tube, and the aspiration tube has an end area significantly larger than the end area of the jet tube. These factors cooperate so that the negative pressure exerted by the aspiration tube creates a suction force that offsets and exceeds the force of the fluid jet.

Core layer for multi-layer composite, having wooden elements

FIELD: vessels and other floating vehicles; equipment therefor.SUBSTANCE: group of inventions relates to woodworking, in particular, to production of slabs and panels. Core layer for a multi-layer composite comprises zigzag-shaped wooden elements having zigzag-like plate-like portions where the lifting portion of the element with the adjacent descending portion of this zigzag shape forms a common vertex. Elements of a zigzag shape are located in the core layer in such a way that two vertices of two zigzag elements, which may be the same or different from each other, intersect with each other at a non-zero angle, and these two elements are rigidly connected to each other at the intersection point. Wooden elements in the core layer have one or more configurations. Wooden elements are randomly distributed in the core layer, or are arranged side by side and one on top of each other in a random way, or randomly arranged, and the vertices intersect with each other at different angles.EFFECT: strength and load-bearing capacity of a multi-layer composite increases.23 cl, 14 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 659 238 C2 (51) МПК E04C 2/12 (2006.01) E04C 2/34 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК E04C 2/12 (2006.01); E04C 2/34 (2006.01) (21)(22) Заявка: 2016118491, 05.11.2014 (24) Дата начала отсчета срока действия патента: Дата регистрации: (73) Патентообладатель(и): ВУД ИННОВЕЙШНС ЛТД.

Olefin-containing composition for producing wood materials, use of olefins to endow crude wood materials with hydrophobicity and method of producing wood materials

FIELD: chemistry. SUBSTANCE: invention relates to olefin-containing compositions for producing wood materials and crude wood materials, use of olefins to endow crude wood materials with hydrophobicity and a method of producing wood materials from crude wood materials. The composition contains crude wood materials from lignocellulose in form of fibres, chips or shavings, as well as olefins or a wax composition. The wax composition contains olefins and additionally paraffin wax in form of long-chain saturated hydrocarbons. The olefins contain an average of 24-50 carbon atoms; more than 50 mol % are alpha-olefins; have a maximum of carbon chain length distribution between 24 and 40 carbon atoms. Bringing crude wood materials (shavings, chips, fibres) into contact with said olefins and optionally together with paraffin wax provides hydrophobisation thereof. Binder is added to said composition to obtain fibreboards, wood chipboards and oriented strand boards.
