A gear case for power window regulators, housing therein a worm gear for use in reducing the rotational speed of a motor in a power window regulator is characterized in that said gear case consists of a thermoplastic resin, and a metal plate at least the greater part of which is buried in said thermoplastic resin by insert molding, said metal plate being composed of a projecting portion extending ...

To effect shelling of crustaceans surface heated crustaceans are shot against a water covered deflector plate in a vacuum chamber, whereby a practically complete deshelling is obtainable without any recirculation. The crustaceans are shot against the deflector plate in very thin flows through periodically operating inlet valves, whereby each single crustaceans will hit the deflector plate and be e...

An open end spinning machine comprises openable spin boxes (20) each with a respective rail element (24) and a movable spin box cover (20). A service tender (16) movable past the boxes has a guide (238) adapted to engage the rail element of a box both when the box is closed and open.

A service tender (16) for servicing operating stations (12) of a package-forming textile machine travels past the stations and senses the condition of a package-holding cradle (134,136,138) at each station (12) to determine the type of service operation required.

There is provided a tool comprising a fully dense sheet of diamond brazed to a substrate. The diamond sheet is manufactured by a chemical vapor deposition process and has a thickness of at least about 0.1 mm. The braze material is preferably a carbide-former. A method for making such tools is also provided.
