There is now provided a tool for chipforming machining of metals and similar materials comprising a high speed steel core and a cover of more wear resistant material than the core. If the material in the core has a carbon content 0.05-0.25% lower than the conventional carbon content for the high speed steel in question, improved properties can be obtained.

The subject of the present invention is an electrohydraulic braking corrector for an electrically driven vehicle. According to the invention, this braking corrector includes means capable of altering the hydraulic braking pressure exerted on an axle as a function of the braking torque of the electric driving motor.

A method and apparatus for the production of iron carbide in a shaft furnace, by reacting a carbon containing reducing gas as the process gas with particulate metal oxide material for an extended residence time at low temperature.

The height at the loading or unloading station of is governed by a hoisted stack platform driven by an electric motor which also positions an angle-sensing arrangement which in turn controls the rate of travel of the platform. A platform carrier (1), supporting the stack of sheets (2), is lifted and lowered by means of chains (3) wound on a drum (4) rotated in either direction by a motor (6) and g...

A device (1) for heating a running synthetic thread has an elongated slot (4) with parallel side walls and an elongated carrier which along with thread guides (3) are assembled into a unified construction. The guides lead the thread in a zigzag path in the slot and the unit is supported in the slot corresponding to the main patent: P 44 35 961.6. The thread guides are made of ceramic material ...

The mill consists of a stator, in which a rotor (1) can be driven. The rotor has several tool holding rings or discs (2) spaced from each other. The grinding tools (3), made of ceramic material, are fitted in the holders where they are secured due to their shape. The tool holder rings have holding slots formed perpendicular in relation to the turning axis. The slots serve for fitting in the grindi...

A process for synthesizing high molecular weight anionic dispersion polymer is disclosed, the process comprising providing a mixture of water, acrylic acid and a stabilizer; cooling the mixture to a temperature of less than 35 DEG C.; lowering the pH of the mixture to less than 4.5; adding ethylhexyl acrylate to the mixture to form an aqueous solution; stirring the aqueous solution; purging the s...

A hydrophilic polyurethane film having at least one surface coated with an organic polymer having pendant perfluoroalkylalkyl or perfluoroalkyl groups as side chains. The organic polymer imparts oleophobicity and hydrophobicity to the polyurethane film. The films have good water vapor transmission rate.; L'invention concerne un film de polyuréthane hydrophile présentant au moins une surface recouv...

In a method for inspecting a dished end face of a nuclear fuel pellet (P), a focused beam of light is emitted to a dish (PA) of the end face of the nuclear fuel pellet while a parallel beam of light is being emitted to the end face thereof. An image of the end face of the nuclear fuel pellet is picked up and the quality of the pellet is judged based on the picked-up image. An apparatus for inspect...

Cured, thermoset plastic articles derived from scrap polyehter-based polyurethanes are obtained by converting the polyurethane to a liquified mixture containing digested polyurethane and cyclic, unsaturated anhydride. A Lewis acid then catalyzes insertion of the cyclic, unsaturated anhydride into the polyether backbone of the polyurethane to give a liquid, unsaturated resin. The unsaturated resin ...

A lift truck with a mast (1) of the industrial or semi-industrial type includes a chassis, driving front wheels (2), guiding rear wheels (3), a combustion engine (4), a driver's position (8) located between the front wheels (2) and rear wheels (3) over the entire width of the truck. The driver's seat (7) is located so as to allow access from either side of the driver's position (8), the driving fr...

A toroidal carcass (1) for road vehicle tires, of the type presenting two annular beads (2, 3) connected by a toroidal reticulated structure (5) defined by two numbers of loops (6, 7) extending in offset radial planes of the carcass (1) and from the respective beads (2, 3) to the center line of the reticulated structure (5); the loops (6, 7) being formed by winding respective continuous cords (8, ...

The fork lift truck has a fork set (2) for handling palettes and loads on them. A control system (4) is connected to the vehicle drive and/or steering and/or braking system and/or fork movement system for automatic operation. Possible routes and transport requirements can be entered. The control system receives signals from a navigation camera (1,3), ultrasound sensor (5) and/or four infrared sens...

The side of the cover of a mattress which is contacted has an alkalinity of > pH 9. The cover is preferably of one or several layers and the alkalinity is conferred by coating, soaking spraying or other means.

A system for nitrate removal from aquariums, both fresh water and marine aquariums, by means of permeable polymeric beads which contain a combination of fermentative and denitrifying bacteria and a carbon source. Preferred beads are beads made from sodium alginate or chitosan. The bacteria, in the presence of the carbon source, are able to reduce nitrate to nitrogen gas. Bacteria which are not har...
