Patent CA-2326896-A1 (CA)
Inventor: GU HONGPING
IPC: B23K26/24
Filed: 2000-11-24
Abstract: A method of laser welding adjacent surfaces of a pair of components to one another. A laser beam impinges upon an exposed surface of one of the components to create a weld zone between the adjacent surfaces. The beam is moved relative to the components to form a weld. The beam is inclined at an acute angle in the direction of movement of the beam so as to provide an inclined front to the weld zone extending through the components to permit gaseous products formed in said weld zone to move along the front and vent to atmosphere. The preferred angle of inclination is between 75° and 55°.

Title: Method and apparatus for manufacturing calendered paper
Inventor: HEIKKINEN ANTTI
IPC: B65H37/00
Filed: 1999-07-12
Abstract: i In the method for manufacturing calendered paper, paper is calendered after drying. The paper is dried (D) down to a moisture lower than the target moisture of calendering. The paper is run via wetting (1) to calendering, wherein at least one of the surface layers of the paper is wetted in the wetting in such a way that the moistening water is absorbed in the surface layer of the paper while at least the central part remains substantially dry. From the paper wetted at least on one of its sides, gradient paper is manufactured by means of gradient calendering by restricting the paper-moulding effect of the calender to the wetted surface layer in such a way that at least the central part of the paper is elastically restored substantially in its original state, whereafter the obtained gradient paper is reeled.

Abstract: Glypicane-1 HSPG ancré à glycosylphosphatidylinositol- (GPI-) est fortement exprimé dans le cancer du sein et du pancréas chez l'humain à la fois par les cellules cancéreuses et par les fibroblastes contigus dans le cas du cancer du pancréas, alors que l'expression de glypicane-1 est basse dans le pancréas normal et dans la pancréatite chronique. Le traitement de deux lignées cellulaires du cancer du pancréas, exprimant glypicane-1, par l'enzyme phospholipase-C spécifique pour phosphoinositide (PI-PLC) a supprimé leurs réactions mitogéniques à deux facteurs de croissance se fixant à héparine: le facteur-2 de croissance des fibroblastes (FGF2) et le facteur de croissance semblable à EGF se fixant à héparine (HB-EGF). Le traitement des cellules du cancer du sein MDA-MB-231 et MDA-MB-468 par PI-PLC a supprimé la réaction mitogénique à deux facteurs de croissance se fixant à héparine, le facteur de croissance semblable au facteur de croissance épidermique se fixant à héparine (HB-EGF) et le facteur-2 de croissance des fibroblastes (FGF-2). Syndecane-1 est également exprimé à des niveaux importants dans des tissus du cancer du sein, ainsi que dans des cellules du cancer du sein, par rapport à des tissus normaux du sein. La transfection temporaire ou permanente d'un produit génétique antisens de glypicane-1 a atténué les niveaux de protéines de glypicane-1 et la réaction mitogénique à FGF2 et HB-EGF. On peut utiliser glypicane afin de détecter le carcinome in vitro et des substances thérapeutiques qui soit se fixent (par exemple, anticorps ou médicaments) à la surface du domaine extracellulaire de glypicane-1, soit en suppriment (par exemple, enzymes) ou en empêchent l'expression (par exemple, produits génétiques antisens), sont efficaces pour retarder la croissance de carcinomes réactifs à glypicane.

Abstract: A non-reusable syringe utilizes a liquid-tight seal between a sliding piston assembly within an elongated barrel. The piston assembly comprises a valve assembly comprising a forward valve and a rear valve that separate upon depression of the plunger for expulsion of the liquid contents. The rear valve that a seal with the barrel and the plunger for drawing in of liquid and the forward valve that forms a seal with the barrel and the plunger for expulsion of the liquid. During liquid expulsion, the two valves separate. A bypass is provided on a plug attached to the plunger which prevents a seal from forming without the rear valve being in position: Thus, when the plunger is retracted after the first use, no liquid may be drawn up into the barrel. The syringe may further include a safety barb and closed ends to prevent tampering or manipulation of the piston apparatus in an effort to eliminate the separation of the two valves.

IPC: G06F3/023
Filed: 2000-01-26
Abstract: A speed typing method and apparatus having multiple letters (Fig. 1) associated with each key (52) of a keyboard (50). By utilizing multiple characters on each key (52), the number of keys (52) would be fewer than the number of letters in the alphabet using this system (100) (e.g., fewer than 26 letter keys for the English alphabet). Each key (52) on the keyboard (52) is associated with a numerical code. The system (100) uses the numerical code associated with a typed word to access a dictionary or table of words stored in memory (12) at a memory location corresponding to the input numerical code. The system may display all of the words available to the user in response to the input code. The user then selects one of the available words to be placed in the document. Alternatively the system (100) may enable display of one or more preferred words. The keys (52) of the keyboard (50) may be contoured so that the user senses the position of his hand in relation to the keys of the keyboard. The typing system (100) is also implemented by a finger-mounted input device having switches. The finger-mounted device may also be used in conjunction with one or more input selection panels. The panels have keys which are selectable by the user in conjunction with the switches.
