  • Aircraft with counterrotating members
    Patent number: 4386748
    Abstract: A rotationally symmetrical supporting member provides lift in response to movement of air over its upper surface, and such air movement is produced by the impeller of a coaxially arranged drive unit, the base of which is connected to the supporting member so that counter torque from the drive unit imparts rotational movement to the supporting member. A carrier which may hold a load or supporting steering flaps is rotatably mounted in relation to the supporting member and to the driving unit.

  • Dental apparatus for preventing loss of precious metal particles
    Patent number: 4385891
    Abstract: Particles of precious metal are recovered from a mixture drawn from the mouth of a dental patient. An enclosure is interiorly divided by a perforated baffle into an upper chamber and a lower chamber. The mixture is introduced into the lower chamber by an inlet conduit which has a substantially smaller cross section than the lower chamber so that a reduced velocity in the lower chamber will permit gravitational settlement of the particles. Residual fluids flow upwardly through the perforated baffle at a relatively low velocity, and they are removed through an outlet conduit which extends into the upper chamber and is connected to a vacuum source.

  • A.C. Electricity power supply system and methods of and apparatus for load control thereon
    Patent number: 4385241
    Abstract: In an a.c. electricity power supply system, to guard against a "blackout", that is to say a cumulative supply failure caused by a fault leading to generating stations being overloaded and having to cease supplying a network, consumers are each provided with means responsive to the supply frequency and operative to reduce or cut out the consumer's load when the supply frequency falls below a predetermined value, which may be different for different consumers.

  • Location of leaks in oil-filled cables
    Patent number: 4384475
    Abstract: To locate a leak in a length of pressure-assisted oil-filled electric power cable, the static fluid pressure is measured at the two ends of the length and the flow into or out of the cable is measured at one end for at least two different pressure supply conditions giving different flow rates while maintaining zero flow rate at the other end of the cable. The measurements are then repeated with zero measured flow rate at said other end. From these measurements, the relationship between flow rate at each end of the cable and the pressure drop between the ends due to flow can be determined and this enables the position of the leak to be calculated. Apparatus for making the necessary measurements is described.

  • Loading device for a machine tool, particularly for machining panels of sheet metal or other materials
    Patent number: 4382395
    Abstract: Automatic loading device for automatically positioning of panels of sheet metal or the like and to transfer the panels to a feeding device of a machine tool, preferably a cutting press. The cutting press cuts a plurality of blanks out of the panel along a given pattern which is stored in a program. The program is controlling the cutting press and the feed device in synchronism in order to provide the blanks, e.g. lids for cans within minimum production time. The time when the loading device is working overlaps the production time for the preceeding panel, i.e. the aligning of the panel in the loading device took place when the preceeding panel is cut. As soon as the feeding device returns to the zero position the loading device transfers the next panel to the feeding device, the panel maintaining its precise aligned position. The feeding device starts to a new feed cycle.
