A surgical instrument for uterocervical conisation. It includes a holder member (1) for diathermic wire (6), this member being intended for mounting in a pistol grip. The wire (6) is tensioned by the holder member such that the wire forms an angle alpha to the longitudinal axis of the holder member, the wire cutting out a cone when the member is turned through a complete revolution. The angle al...

PURPOSE:To improve the control performance of follow-up of an unmanned vehicle to a guide line by correcting the gain for detection of deviation between the vehicle and the guide line according to an actual steering angle. CONSTITUTION:An electromagnetic guidance type unmanned vehicle contains a steering wheel 2 and drive wheels, and a controller 4 is attached to the body of the vehicle for drive ...

Each transport device contains at least two drive wheels which are driven at individual speeds VA and VB and which are pivotable by related steering angles alpha and beta . Identical servo-drive units are associated with the drive wheels and their mode of operation and mutual coupling is adapted by switch devices to the steering angles alpha and beta such that the required speed adjustment ...

For the shelling of crustaceans, e.g. shrimps or krill, the preboiled crustaceans are reheated at short duration to a temperature, at which the body liquid just inside the shells is slightly below the boiling temperature, whereafter the crustaceans are subjected to a sudden pressure drop, such that the liquid just inside the shell boils up. With the shells thus loosened the crustaceans are caused ...

The specification discloses a fire retardant composition a plastic base thereon, a process making for same and a building component based thereon wherein the fire retardant comprises chemicals which when added to the plastic resin composition will undergo fractional, endothermic reactions under the action of high temperatures. The most preferred chemicals disclosed in the specification, and their ...

A measuring device for long-term installation in a bore in a rock formation for detecting gradual changes in bore diameter, especially gradual constriction which might affect the condition of radioactive waste deposited in the bore, utilizes telescoping parts under outward spring pressure. One of the two elements of the transducer which by the relative displacement of these elements measures chang...

A control system for the clutch of a torque converter to allow direct drive operation of the torque converter in more than one transmission drive train speed level. The fluid pressure normally causing coupling of the clutch is interrupted by a blocking device when a change in drive trains occurs resulting in a lower fluid pressure on one of the drive train operating clutches, and that interruption...
