Patent NL-6812858-A (NL)
Title: Metal test samples for spectrographic or x ray fluores - cent analysis
IPC: C21C7/10
Filed: 1968-09-09
Abstract: Metal test samples for spectrographic or X-ray fluorescent analysis. N7-. Taken in the form of powder or turnings from the article to be tested, are formed into a compact piece by induction melting in a ceramic crucible, under a protective gas. The heat is developed in the sample and the excess temperature over the melting point can be accurately controlled to prevent or minimise loss of more volatile components. The agitation produced in the melt leads to a completely homogeneous sample.

Title: Bottle cap
IPC: B65D41/44
Filed: 1985-04-12
Abstract: A bottle cap of the tear-off type, particularly an easy-to-open cap for wide mouth bottles, in which a central top wall which covers the top portion of the mouth of the bottle is connected to a lateral band which surrounds the opening of the neck of the bottle and is bent under the edge of the neck to grip the cap, and a tear-off tab, bounded by one or more score lines, extends from the top wall through the lateral band and an angular sealing is interposed between the mouth of the bottle and the top wall and the lateral band. The angular sealing is bonded to the undersurface of the central top wall at a bond area inside the score line or lines, whereby, when the cap is broken by lifting the central top wall by means of the tear tab, the angular sealing is lifted with the central top wall in one piece and slips off from underneath the lateral band thereby freeing or loosening the lateral band from the mouth of the bottle.The sealing can also be bonded to the tear tab at the area bounded by the score line or lines towards the lateral band, to make the lifting of the sealing itself along with the central top wall easier, without breaking it.

Title: Instrument which allows sutures to be performed endoscopically with classical suture threads
IPC: A61B17/04
Filed: 1990-08-16
Abstract: This invention relates to an instrument which allows sutures to be performed endoscopically with classical suture threads, by means of rigid endoscopes.  The use thereof will thus be viable in endoscopic techniques of General Surgery, Urology, Gynaecology, Gastroenterology and Orthopaedics.  Basically it is made up of a cylindrical tube with a bore of 27 Ch or close thereto, of variable length depending on the field of application. The cylinder is crossed throughout its length by four pipes: two with an approximate diameter of 1.2 mm, continuing in one of the ends with two tubes with a lumen of the same bore and with a length of about 6 cm, with the curved ends turned towards each other, with a distance of about 1.5 cm between them.  In each of the pipes, and in the tubes which are the extension thereof, there is a longitudinal slot about 0.2 mm wide along the entire length.  These pipes are intended to allow the suture material to pass from the outside to the inside and back again, and the slots allow the suture thread to be conveyed from the outside to the edges of the wound to be sutured. In the cylindrical tube there are two other pipes of greater bore: one for passage of the endoscopic lens, the other to allow passage of the auxiliary material for endoscopic surgery. These two pipes communicate with each other throughout their length. The suture material is made up of a filament of hard, but flexible and indeformable plastic, or flexible and indeformable metal thread, with a diameter of about 1 mm and a length about 10 cm greater than double the length of the sheath of the endoscopy instrument to be used, one end being pointed and the suture thread, with a length of about 60 cm, being fixed at the other end. <IMAGE>
