Such an apparatus comprises a rotary cutting roller (1) with one or more peripheral radial knives (9) which are angularly spaced apart from eac...

An automatic clutch control apparatus controls a clutch on a motor vehicle based on a learned position to fully engage the clutch and a learned position to start engaging the clutch. The automatic clutch control apparatus includes means for determining a basic amount of engagement of the clutch based on operating conditions of the motor vehicle, and means for determining an adjusting amount corres...

The open edge (5) of a plasticboard (1) is moved into a heating and sealing unit (13) having a metal form (14) with a U-shaped cross-section. A spacing tape (27) and a release tape (28) line the metal form (14). An induction or resistance heater (15) is coupled to the metal form (14) to raise the temperature thereof and heat the open edge to form a molten plastic (30) edge wall, with the outer edg...

A feed accelerator system for use in a centrifuge, the system comprising a conveyor hub rotatably mounted substantially concentrically within a rotating bowl, and an accelerator including a cone-shaped inside surface disposed between an accelerator base and an accelerator small diameter section. The accelerator is secured proximately to its base within the conveyor hub so that the accelerator rota...

En fremgangsmåte for elektroslagg-raffinering av metall. Fremgangsmåtenomfatter tilveiebringelse av et raffine-ringskar som inneholder et elektroslagg-lag som flyter på et lag av smeltet,raffinert metall. En støpeblokk av uraf-finert metall senkes ned i karet tilberøring med det smeltede elektro-slagglag. En raffineringsstrøm føresgjennom slagglaget til støpeblokken,slik at overflaten smelter ved ...

A method for the electroslag refining of metal is provided. The method involves providing a refining vessel to contain an electroslag refining layer floating on a layer of molten refined metal. An ingot of unrefined metal is lowered into the vessel into contact with the molten electroslag layer. A refining current is passed through the slag layer to the ingot to cause surface melting at the interf...

An apparatus (11) for inspecting the sealing surface (86) of a container (15) for dips, saddles and lean is disclosed. While the container (15) is rotated, a beam (77) of light is projected horizontally above and through a finish portion of said container. An optical detector (100) detects the height of said sealing surface (86) by detecting the location of a minimum in the light beam. Dips in the...

The fork lift truck, which is intended for off-road work, has at least one pair of steerable wheels and at least one pair of driven wheels. The truck has a chassis with a recess in its middle portion. The engine is mounted transversely to the longitudinal axis of the chassis in the region of the rear wheels. The driver's cab (13) and the vehicle controls are mounted in the recess formed in the cha...

A safety ski-binding having force transmitting surfaces which are inclined at an angle which corresponds substantially to the angle of friction. The force component acting in the direction of release of the sole plate created by the additional load compensates for the friction, so that the release resistance is not influenced even for a heavy load from the ball of the skier's foot even for the pur...

The present invention relates to foamable thermosetting polyurethane structural adhesive composites and compositions and processes for producing the same comprising dispersing a water-generating curing composition into a polyurethane base resin to form a nonactivated adhesive composite, and activating the same by heating to form an adhesive composition. Another aspect of the invention relates to d...
