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.

According to the invention, more than 50% of the pulp is chemically modified thermomechanical pulp, so called CTMP. The impregnating substance is preferably paraffin.
Abstract: A paint for outdoor surfaces and surfaces in wet rooms, especially for concrete walls exposed to strong weathering, contains pigment, binder of which a part is (meth)acrylic polymers and/or copolymers, volatile solvent(s), fillers and optionally known additives and it is characterized by (a) having a pigment-volume concentration of 47 to 65%, preferbly 55 to 60%, (b) containing diatom shells as part of the filler, and (c) containing one or more oligomieric alkyl-alkoxy-organosiloxanes as part of the continuous binder phase. There is obtained on one hand a high degree of imperviousness to water in the liquid form and on the other hand a high degree of diffusion of aqueous vapor.
Abstract: Rod elements with variable section, straight and discontinuous allow erection of flat and spatial structures. There are also provided flat panels with turned back edges and surface lining panels which can be associated with said flat panels as well as roofing panels which can be partially overlapped. Angle elements with L-section allow joining of several structures in miter, T and cross joints.

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.

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.
Abstract: A display system according to the present invention is provided with a projective display unit for projecting a display image of a display device which displays various data, onto a front glass of the vehicle and forming a virtual image of the display image in front of the front glass, and a position adjusting means for adjusting the position of the virtual image formed in front of the front glass by shifting a projective optical axis of the display image extending to the front glass, whereby the whole surface of the front glass in front of the driver can be utilized as a display image projection surface and hence the virtual image of the display image can be formed in a desired position aligned with the line of vision of the driver without obstructing the front sight of the driver.
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.
Abstract: A nut in combination with a deformable plastic plug is provided so as to produce a torsional reistance when the nut is screwed onto a similar male thread such as a bolt. The plug comprises an inner core wedge and an outer sleeve which will expand upon insertion of the core. The sleeve is placed into the nut, leaving at least one complete turn of the thread free, and the core is wedged into the sleeve forcing it to deform into the thread.
