The present invention relates to a method of making a cemented carbide with submicron grin WO grain size consisting of WO, 6-12 wt-% Co and 0.1-0.7 wt-% Cr using conventional powder metallurgical technique mixing, pressing and sintering. According to the method the WC-grains are coated with Cr prior to mixing. As a result a cemented carbide with improved properties is obtained.

A method of managing project time/resource data and documents in response to commands given by a user. The method includes setting up a user interface for bidirectional communication with a user of a computer system. The user interface displays symbols to the user and receives a selection made by the user via a pointer. The user interface displays several first symbols simultaneously to show proje...

A mechanism for regulating the closing speed of a rolling fire door during an emergency condition. The speed regulating mechanism includes a viscous speed governor which is operatively connected to the support shaft of the fire door for providing a speed regulating damping torque as the door moves to a closed position. Methods for regulating the closing speed of a fire door during an emergency con...

A nasal atomized shower apparatus has a body defining an atomizing chamber, a pressurized air injector arranged at the region of feed of washing liquid to be atomized and facing the atomizing chamber and a conduit for discharging the washing liquid. The apparatus further includes a valve associated with the body, and adapted to control the pressure of the pressurized air for releasing the excessiv...

The present invention refers to an absorbent article, preferably a disposable sanitary napkin, provided with side flaps, with adhesive regions that aid in fixing said absorbent to the wearer's panties, keeping it in the correct position and avoiding the occurrence of leakage. One of the main objectives of this invention is to provide a sanitary napkin provided with a single enveloping sheet that s...

The system for the movement of bobbins has carriers (22) which project from the conveyor (20) at the sliding path (5) for the under side of the base plate (11) of the pallet (10) which carries the bobbin. In the event of a blockage, the carriers (22) are pulled clear of the pallet base plate (11) so that the pallet (10) or the carrier (22) gives across the direction of travel. The vertical gap be...

A bird anti-perching device is described having a rotatable cylindrical member extending between two support members and capable of rotating freely if a bird lands thereon, thereby to form an unstable perch. The device can be attached to the ledge of a balcony in a number of ways to prevent birds from alighting on the balcony.

A process for preparing tosylbenzyl formamides.

An interposes assembly includes an insulating plate with passages extending through the thickness of the plate and metal contacts loosely confined. in the passages. The contacts include noses that project outwardly from the plate for engagement with contact pads on overlying and underlying circuit members.

La présente invention concerne un générateur électrochimique au lithium comportant au moins une électrode composite comprenant un matériau actif, et un premier et un second électrolyte solides distribués de façon non-homogène dans le composite. Le premier électrolyte solide est de nature minérale, vitreux ou partiellement vitreux, et est un conducteur spécifique des ions lithium, et est localisé p...

An environmentally non-intrusive multiple turbine unit for adjustable deployment in water. The turbines are captured in a shroud having an integrally formed augmentor ring and ballasting member to improve efficiency. The multiple turbine arrangement effectively counteracts the rotational counter-torque of individual turbines, thereby enabling stable deployment of the unit without requiring rigid s...

Water is supplied from a ditch or pipe to a measuring well via an inlet pipe (1). A pump (2) sensitive to contaminants is used to remove water from the well for testing, and at the same time it urges water through a measuring tube in a flow meter (5). A precision water level gauge is used to regulate the amount of water removed by the pump. Water levels (8, 9) are set for pump start-up and switch-...

The invention concerns a machine that can be used for washing scraps of fibrous materials, such as fibreglass, carbon fibre, polyamide, or the like, which have been impregnated with resin, for allowing the extraction of the resin with the use of the appropriate solvents. The machine comprises a closed, hollow container having one inlet and one outlet, the container enclosing at least one conveyor ...
