Abstract: Dans les instruments pour mesurer les niveaux de liquide contenu dans les gigantesques réservoirs souterrains, comme ceux des stations d'essence, on utilise généralement une longue baguette graduée le long de sa surface extérieure qu'on introduit directement dans le réservoir, et qu'il faudra essuyer entre chaque mesure qui sera prise avec cette baguette. La présente invention est aussi une longue baguette graduée en chiffres le long de sa surface extérieure, mais qui a la particularité d'avoir la forme tubulaire, avec un intérieur cylindrique de façon à permettre à un flotteur, également de forme cylindrique, de pouvoir se mouvoir é l'intérieur de la baguette comme le ferait un piston à l'intérieur d'un cylindre. Ce flotteur cylindrique qui se déplace à l'intérieur de la baguette, est muni d'un cliquet constitué par une petite tige cylindrique, allongée et flexible qui, lorsqu'elle sera mise en interaction avec un réseau complexe de rainures moulées dans la surface interne de la baguette, permettra à la baguette, de pouvoir prendre des mesures de niveau de liquide de façon rapide, efficace et automatisée. De plus, il ne sera pas nécessaire d'essuyer la baguette sur toute sa longueur entre chaque mesure prise avec la baguette.

Title: Method and device for coating of a moving base
Inventor: RANTANEN RAUNO
IPC: B05C11/04
Filed: 1992-05-05
Granted: 2000-10-24
Abstract: The invention concerns a method for coating of a moving base, such as the face of a back-up roll, paper or board web, or equivalent, with a coating agent. In the method, a blade coater is employed in which a coating blade included in the blade coater and installed in a blade holder is loaded in the area between the blade holder and the tip of the coating blade 'toward the moving base by means of a loading member. The coating blade forms a substantially small angle in relation to the moving base. The coating quantity applied onto the moving base is regulated by adjusting the blade angle and/or the loading of the coating blade. The coating blade is loaded towards the moving base, in the area between said loading member and the tip of the coating blade. The coating blade is additionally loaded by a second loading member so that the loading produced by the second loading member prevents separation of the tip of the coating blade from the layer of coating agent formed on the moving base so as to prevent cavitation in the area of the tip of the coating blade.      The invention also concerns a device that makes use of the method.

Title: Drip-catcher
Inventor: JENSEN BRIAN VANG
IPC: B65D5/74
Filed: 1991-09-17
Granted: 1998-07-14
Abstract: The invention relates to a drip-catcher for, for instance, a bottle and intended for preventing dripping and drops seeping from the bottle orifice during pouring. The drip catcher of the invention simply consists of a piece (1) of flexible and elastic foil material, preferably plastic material foil having the thickness of .1-.2 mm. The diameter of the piece of material may be 60-80 mm. When used as a drip-catcher the piece of material is rolled into an oblong cylindrical form andinserted in the orifice of the bottle. Due to its elasticity the piece of material will positively engage the orifice and constitute a tube-formed outlet spout. Due to the          (see fig. I) small thickness of the foil material and its liquid-repellent nature this spout cuts off the jet very efficiently and is also a very efficient drop-catcher. The drip-catcher of the invention is extremely simple and cheap. Its use is uncomplicated and it is universally applicable because the piece of material adjusts itself to the bottle orifice irrespective of its size. The effect of the drip-catcher is remarkable due to the small thickness and liquid-repellent surface of the material.

Abstract: A system for termite detection and control is provided by a subterranean bait station having a perforated outer housing permanently implanted in the terrain below ground level, and a perforated cartridge removable received within the housing. The openings in the housing and the cartridge are in alignment with each other when the cartridge is fully received within the housing in its operational position.      The cartridge received within the housing will initially contain a non-toxic bait material for diagnosing or assessing the level of a termite infestation; the bait cartridge is periodically removed from the housing to inspect for termite activity. If termite activity is detected, the non-toxic bait cartridge is replaced in the housing with a correspondingly perforated pesticide-containing bait cartridge for extermination of termites. Removal, replacement and substitution of the non-toxic and pesticide containing cartridges does not disturb pre-existing termite foraging galleries as a result of the precise alignment of the openings of the housing and the removable, exchangeable cartridges. The system mae also be used for above-ground termite detection and control by externally mounting an appropriately modified housing to an outer surface of any article to be monitored, such as a timber.

Abstract: The base of solder bumps is preserved by converting the under-bump metallurgy between the solder bump and contact pad into an intermetallic of the solder and the solderable component of the under-bump metallurgy prior to etching the under-bump metallurgy. The intermetallic is resistant to etchants which are used to etch the under-bump metallurgy between the contact pads.  Accordingly, minimal undercutting of the solder bumps is produced, and the base size is preserved.  The solder may be plated on the under-bump metallurgy over the contact pad through a patterned solder dam layer having a solder accumulation region thereon.  The solder dam is preferably a thin film layer which may be accurately aligned to the underlying contact pad to confine the wetting of the molten solder during reflow.  Misalignment between the solder bump and contact pad is thereby reduced.  The solder bumps so formed include an intermetallic layer which extends beyond the bump to form a lip around the base of the bump.  This lip provides extra protection for the solder bump.
