  • Patent number: 4351384
    Abstract: The invention relates to the application of coolant onto the surface of an electromagnetic D.C. cast ingot or billet where two coolant streams are directed to the solidified or partially solidified metal so that the two streams intersect a short distance away from the metal surface. By controlling the velocity and/or volume of one or both coolant streams, the point of impact on the metal surface can be brought closer to the discharge end of the inductor and thereby increase cooling rates. In this manner the excursions of molten metal which form the icicle-like appendages on EM cast ingot or billet can be effectively eliminated. When the end of the ingot or billet passes the area of coolant impact and the risk of such excursions is slight, the point of coolant impact can be lowered to a more conventional level for the remainder of the cast.

  • Patent number: 4351401
    Abstract: The invention relates to the design of earth bore-hole drill bits embodying shaped preformed cutters containing hard abrasive materials, such as diamonds, the cutters being mounted in companion preformed sockets in the hard metal bit matrix. The extent of penetration of the preformed cutters into the formation being drilled is controlled by providing surface set diamonds embedded in the matrix at or adjacent to its gage portion, the surface set diamonds projecting from the matrix to a much lesser extent than the preformed cutters. As a result, the surface set diamonds can penetrate into the formation only to the extent determined by engagement of the adjacent face of the matrix with the formation. Although the preformed cutters project from the matrix to a greater distance than the surface set diamonds, their extent of penetration into the formation is no greater than that of the surface set diamonds.

    Abstract: An articulated vehicle including a front member having at least two axles, the forwardmost one of which is steerable, and a rear member, connected to the front member by a pivotal joint, having at least one axle and an engine for driving that axle. A first transducer produces a signal representative of the angle between the steerable axle and another axle of the front member, and a second transducer produces a signal representative of the buckling angle between the vehicle members. A comparator receives the transducer signals and produces a signal in the event that the actual buckling angle is less or greater than a theoretical buckling angle, the latter being determined by the signal from the first transducer. A device, such as a piston and cylinder device, responds to the comparator signal by producing a torque about the pivotal joint to increase or decrease, as the case may be, the actual buckling angle so that it approaches the theoretical buckling angle.

  • Patent number: 4351413
    Abstract: A landing net assembly (10) provides a controlled deceleration landing device for pole vaulters, high jumpers and the like in such a way that the impact of a free-falling body and the rate of displacement of the landing net is dampened in a controlled manner. Each of a plurality of damping devices includes a supporting post (12, 14) which contains a fluid (72) and float (76) submerged in the fluid (72), the float (76) being connected by tendons or cords (82) to the landing net (18) so that when the (18) net is displaced the float (76) is displaced within the fluid (72). In this manner, the viscous drag force of each float as it moves through the fluid and the buoyant force of the float in the fluid dissipate the initial impact of the free-falling body and damp the rate of displacement of the net.

  • Patent number: 4351416
    Abstract: An elevator control device which selectively employs an operational mode in which the cage of the elevator is run at a maximum rated speed or an operational mode in which the cage is run at a speed lower than the rated speed as determined by distance codes read out from a memory. The cage is accelerated in accordance with an acceleration signal the value of which is determined by the total distance between the start and stop floors. A deceleration instruction signal is produced in accordance with the difference between the acceleration instruction signal and the distance to the floor at which the cage is to be stopped. The acceleration instruction signal is compared with the deceleration instruction signal and a decision is made as to which is utilized as a speed instruction signal to a motor operating the elevator cage in accordance with which is the larger.

  • Patent number: 4351418
    Abstract: A brake compensator for a vehicle using a resilient device or resilient elastomeric material which is connected to the cable or the cable sheath of a cable-controlled brake, and is extended or compressed in response to a force applied thereon when a brake is applied. In one embodiment, the resilient device is disposed between the sheath and the frame of a vehicle, and is arranged so that the control cable passes directly through the compensator and to a brake caliper. In a further embodiment, the brake compensator may be disposed between the sections of sheath around a continuous brake cable. This arrangement avoids the need for an assembly to mount the compensator to the vehicle frame. Apparatus is shown for pre-loading the resilient device and thereby advantageously adjusting for different product and rider characteristics. Additionally, structure may be provided for limiting the maximum compression, beyond which the cable and sheath operate in a conventional manner.
