Title: Method and apparatus in ropeless tail threading in a multi-roll calender
Inventor: LAITIO JUHA
IPC: D21G1/00
Filed: 2003-05-22
Abstract: The invention relates to a to a method and apparatus in ropeless tail threading in a mufti-roll calender (10). The threading tail (T) is guided through the multi-roll calender (10) in such a way that, before the multi-roll calender (10), the threading tail (T) is guided first of all to the broke processing and then cut when the tail threading begins.      The tail threading takes place in stages, so that at least once during the tail threading the threading tail (T) in connection with the multi-roll calender (10) is guided to broke processing and cut, after which the, tail threading is continued, once the previous stage has succeeded.

Title: Sd1 gene involved in plant semidwarfing and uses thereof
Inventor: OKAWA MIHO
IPC: C12N5/10
Filed: 2002-06-07
Abstract: The present inventors presumed that the sd1 gene was the C20 oxidase gene, and isolated and identified the rice counterpart of Arbidopsis C20 oxidase gene. As a result, it was revealed that the rice sd1 gene encodes a novel C20 oxidase.  Further studies showed that mutation in this gene led to plant semidwarfing. Utilization of the plant sd1 gene is expected to increase the yield of plants, particularly useful agricultural crops and ornamental plants, to add aesthetic value to ornamental plants through dwarfing, and also to increase the yield and efficient breeding of dwarfed plants by marker selection.

IPC: A61M5/315
Filed: 2002-05-09
Abstract: A injector comprises a cylindrical barrel to which a needle is to be attached, and a plunger having a gasket on the tip thereof which slides within the cylindrical barrel. The gasket is in a substantially discoid form and has an annular groove to provide a bending portion which can bend either towards or away from the plunger. When a medical fluid is introduced into the barrel by retracting the plunger, the negative pressure inside the barrel results in the bending portion bending away from the plunger causing the gasket to tightly contact the inner wall surface of the barrel. When the medical fluid is discharged by pushing the plunger in the opposite direction, the positive pressure bends the bending portion towards the plunger so that the gasket again tightly contacts the inner wall surface of the barrel.
