  • Patent number: 4721055
    Abstract: A remotely operated submersible vehicle (21), wherein the vehicle includes flotation cells (62) to provide positive buoyancy, and the vehicle is connected to a disposable clump weight (22) of sufficient weight to overcome the positive buoyancy. The connection between the clump weight and the vehicle is by way of a cable (25) which can be wound onto and off from a drum winch (45) within the vehicle to control its height off the seabed (23). The trim of the vehicle is maintained by adjusting the horizontal position of a cable guide (43) through which the clump weight cable (22) passes, the cable guide (43) being moved longitudinally and transversed by hydraulic cylinders (47). Control signals to control and monitor the operation vehicle are provided via an umbilical cable (29) extending from a ship (76) or platform on the surface.

  • Patent number: 4712524
    Abstract: A method of delivering fuel to an internal combustion engine comprising delivering individual metered quantities of fuel into a conduit, and propelling each individual metered quantity of fuel along the conduit by an individual gas pulse. During the time interval between the respective gas pulses that deliver the metered quantities of fuel there is established a secondary gas flow in the conduit so as to limit variations in the quantity of fuel retained in the conduit as the metered quantity of fuel varies with engine fuel demand.

  • Patent number: 4711499
    Abstract: The trailer bed plate (3) is tipped by the towing vehicle moving backwards. The tow bar (1) is hinged to a sliding hinge (2) disposed on the underside of the bed plate, and connected via at least one connecting rod (4) to wheel-supporting frame (5) which is hinged to the rear of the bed plate at (11). When the sliding hinge is released to slide rearwardly, the rod-frame-bed triangle changes shape at the same time as the trailer tips. The trailer may then be locked in this position and tilted back about the wheels so that its bed plate occupies a higher horizontal plane than that occupied in the running position. The trailer then constitutes a table, or work bench.

  • Patent number: 4708878
    Abstract: A method for the temperature control of a liquid and an apparatus to effect such a method wherein the heating of the liquid is carried out by irradiation with acoustic ultrasonic waves. Temperature measurement is effected by a probe immersed in the liquid or by contact-free measurement of infra-red radiation from the liquid. Temperature control is effected by comparison of the measured temperature with a predetermined desired temperature. Since the acoustic ultrasonic heating is thermally inertialess, extreme accuracy of temperature control is possible.
