Abstract: The whole propulsion mechanism of a boat including an engine 30 is assembled into a housing 37 which carries a propeller 31, thus forming a propulsion unit which may be manufactured and assembled independently of the boat. The housing 37 is received by a well 28 formed in the hull of the boat. The walls of the housing 37 and well 28 isolate noise and vibration of the engine 30. The boat is buoyant both when the propulsion unit is received in and removed from the well 28 and fitting of the unit requires no water-tight seals to be made. In preferred embodiments of the invention the hull is moulded from fibre-reinforced plastics material. In alternative embodiments the boat has a water-jet propulsion system. The housing may be circular and rotatable to effect steering.   <IMAGE>

Abstract: The method is for monitoring and controlling the performance of a rail borne vehicle, in which the latter automatically monitors the speed dependent upon information relative to speed and distance provided by fixed signalling points arranged along its track. The speed data are fed by coded track conduits fitted in the rails themselves. Information received from the rail conduit can increase that which is restrictive and received from earlier signal points. The specific lengths between signalling points along the tracks allow for braking from 120 km/h to stop, or alternatively for speed reduction from 160 km/h to 120 km/h. Since the distance to travel to the next signalling point is transmitted at each point passed, the automatic train control equipment on board the vehicle can calculate the exact point at which the brakes should be applied.

Abstract: A tool holder for a drill capable of performing only rotary drilling or the combination of rotary and percussive drilling includes a tubular retainer member in which the shank of a tool can be inserted. Locking members mounted in the retainer member fit into recesses in the tool shank for holding it in the retainer member. During percussive drilling the locking members are axially displaceable in the recesses and the tool experiences a certain amount of axial play, however, when only rotary drilling is performed the locking members are held against axial displacement by stops so that the tool does not have any axial play. One stop forms a part of the retainer member and another stop is part of a member slidably displaceable relative to the retainer member.

Abstract: A clamping head is equipped with angular spreading bodies which engage a winding core. Impingement of the winding core end face on a stop moves the spreading bodies longitudinally on a bevel of the clamping head core against spring force, thereby spreading the spreading bodies so as to engage the inside circumference of the winding core. To that end, the clamping head features a sleeve-shaped part which centers the winding core and is provided with longitudinally extending slots for the angular spreading bodies. A shank of each spreading body, extends radially outward, forms at least indirectly the stop for the winding core end face. Longitudinally movable in the slot, the other shank of the spreading body has a projection which protrudes radially inward and interacts with the bevel of the clamping head core so as to cause the shank to move beyond the peripheral surface of the sleeve-shaped part as the projection runs onto the bevel. The clamping head secures the winding core in both nonpositive and form-fitting fashion in that the spreading body shanks dig into the winding core. It is distinguished by a design from components which are relatively simple to manufacture and of which the spreading bodies exposed to wear can be replaced easily.

Abstract: Ultrasound is used to determine the degree of adherence between an explosive (4) and a delimiting surface of a delimiting wall (2, 3). The measurements are carried out in two different runs, on the one hand in the form of a preparatory measurement run in which the explosive has not yet been applied against the delimiting surface and, on the other hand, in the form of a main measurement run in which the explosive has been applied. In the measurement run without explosive, the delimiting surface may if appropriate have been provided with a lacquer layer (5) designed to increase the adherence of the explosive. In both measurement runs, two different measurement series are carried out. The ultrasound is directed towards either the inner surface of the delimiting wall or its outer surface. Reflected ultrasonic signals are received and recorded. Ratios between related inner surface echoes and outer surface echoes are calculated, and the difference between the ratios for the preparatory measurement run and the main measurement run represents a very good measurement of the degree of adherence.
