Title: Metallic pipe element for a flue
Inventor: ZAMBONI ELIO
IPC: F23J13/04
Filed: 1996-04-12
Abstract: A pipe element (10) for a flue is disclosed, which comprises a metallic circular pipe body having a first predetermined diameter; said element is further provided, close to a first and thereof, with an area (11) having a diameter which is slightly larger than said first diameter. The edge of the metallic pipe end having a larger diameter is internally folded, and it is provided with a series of radial cuts (12) which allow said end to be folded. Furthermore each portion which is comprised between two radial cuts in on one hand folded in such a way as to be parallel to the pipe longitudinal axis, on the other hand folded in such a way as to perpendicular to said axis. In this way a metallic locking nut is formed inside of the pipe, in the larger diameter area. The other pipe is provided, by means of a mould, with a series of ribs (15) which are adjacent to each other and which form a thread suitable for cooperating with said locking nut in order to join together a pair of adjacent pipes. The joining operation is carried out in a very simple way, by inserting one end of a pipe into the conjugated end of an adjacent pipe and by carrying out a rotation about the pipe axis until the respective locking nut and thread elements reach an abutment position.

Title: Inrichting voor het naspoelen van glazen.
Inventor: STEFAN WERNER MULLER
IPC: A47L15/00
Filed: 2015-10-21
Granted: 2017-05-09
Abstract: Deze inrichting voor het naspoelen van glazen heeft betrekking op een reinigingsinrichting voor glazen, die gebruikt wordt in spoelbakken van horecabedrijven. Op deze reinigingsinrichting is, van dezelfde auteur, een Nederlands octrooi uit 2001 van toepassing onder nummer 1014162. De naspoelinrichting wordt geïntegreerd in de reinigingsinrichting en werkt onder waterdruk. Door een glas in deze reinigingsinrichting te schuiven, wordt hierdoor in de naspoelinrichting een klep geopend, waardoor het water in de aanvoerbuis vrije loop heeft en het glas tijdens het omhoogtrekken via twee of meer sproeiopeningen van binnen en buiten naspoelt. Deze klep is voorzien van een zelfwerkend sluitmechaniek, waarbij de tijdsduur van de open stand in te stellen is, zodat de hoeveelheid spoelwater nauwkeurig bepaald kan worden. Door dit extra toegevoegde water kan de vaste circulatie van de spoelbak enorm verlaagd worden, waardoor het waterverbruik tot een kwart teruggebracht kan worden.

Title: Method for planting chrysanthemums in saline lands
Inventor: QIAN QIAO
IPC: A01G22/60
Filed: 2020-06-02
Granted: 2021-09-08
Abstract: The disclosure relates to a method for planting chrysanthemums, in particular, to a method for planting chrysanthemums in saline lands. The disclosure provides a method 5 for planting chrysanthemums in saline lands. The method employs ridge planting, uses the ﬁlm covering technology to prevent alkali while maintaining water, and then uses an alkali-absorbing layer to realize the purpose of isolating the planting area from the alkali layer. The alkali-absorbing layer may seep into the ground, but may not allow the alkali in the ground or on both sides to enter the ridge, The hardwood sawdust, as 10 the alkali-absorbing layer, may absorb a large amount of salt seeped with water in the soil, and also prevent the salt in the lower part of the alkali-separating layer from moving upward and being brought to the planting layer with the evaporation of water. The sawdust slowly rots over time, which may better improve an aggregate structure of the soil and increase organic matters of the soil.

Abstract: Propulsorul transversal cu clapeţi, conform invenţiei, este destinat creşterii capacităţii de manevră a navelor la viteze foarte mici de deplasare în spaţii de manevră limitate, prin dezvoltarea la prova sau la pupa a unei forţe perpendiculară pe planul diametral al navei, obţinută prin absorbţia apei de la fundul navei şi refularea jetului de apă prin bordajul navei. Reglarea mărimii şi a direcţiei forţei transversale se efectuează cu ajutorul a doi clapeţi (E, E) în formă curbă (7',7",10) fiecare clapet putându-se roti în jurul unei axe orizontale (9',9") amplasată în zona mediană a cotului de tubulatură, astfel încât în poziţia deschisă a clapetului suprafaţa acestuia să devină şi pală de dirijare a apei, concentrică cu peretele interior al cotului (6). Alungirea pronunţată a secţiunii transversale a jetului este realizată prin pomparea apei cu ajutorul a două elice navale (2', 11) cu pas fix având discurile active parţial suprapuse. Barele profilate (4) ale grătarului de protecţie pentru intrarea apei în conducta verticală pot juca şi rolul de clapete de schimbare a direcţiei apei în orificiul de intrare, prin rotirea lor simultană în jurul unor axe de rotaţie perpendiculare pe planul diametral al navei. Avantajele principale ale propulsorului transversal conform invenţiei constau în creşterea eficienţei în toate situaţiile de exploatare ale acestuia, prin micşorarea pierderilor hidraulice, întârzierea momentului apariţiei fenomenului de scădere majoră a mărimii forţei transversale precum şi prin posibilitatea obţinerii propulsiei navei la vitezele mici necesare manevrelor portuare.
