Abstract: A sputtering apparatus includes a rotatable array plate and a magnetic array including a group of permanent magnets arranged around the plate periphery in one or more quadrants. Each magnet is perpendicular to the plate, having a pole of a first polarity facing toward the target. A bar permanent magnet is affixed to the plate within the same quadrant of a group of magnets and is located between a center axis of rotation and the magnet group. The bar permanent magnet is perpendicular to the plate, having a pole of a second polarity facing toward the target. The magnets create a closed-loop static magnetic field that is substantially triangular in shape, concentrated in the quadrant, and offset from the center axis of rotation. The magnets in one quadrant may be replicated to fill up to four quadrants, and additional bar magnets are arranged to create a rotating magnetic field at the target that patterns the plasma to a maximum plasma density in the shape of a kidney.

Abstract: This invention relates to processes for modifying the flow characteristics of slurries, particularly mineral slurries such as red mud from the Bayer process, using water-soluble polymeric emulsions to increase the slurries' angle of repose.

Abstract: A safety vehicle incorporating an impact member, a collision sensor and a safety device. When the vehicle collides with a typical pedestrian, he is struck by the impact member, which is so placed that it tends to make him fall onto a surface of the vehicle, e.g. the bonnet. The safety device, responding to the sensor, then moves from a stowed position to an operating position in which it restrains him from falling off the surface again. The stowed location of the device and its path of movement to its operating position are chosen so that it does not impede, but may actually assist, the movement of the pedestrian onto the bonnet.

Abstract: Apparatus for timing the occurrence of a variety of control signals by using a storage device forming a pair of registers at each of a plurality of addressable locations and storing in one register a constant value while its corresponding register serves as an accumulator. A repetitive sequence of clock signals is continuously generated and each signal in a sequence is peculiar to a set of one or more addresses and, with other preconditions is operable to effect a comparison between the stored constant and accumulated value at that address. If the accumulated value is not equal to the constant, the accumulated value is incremented by one and both values are stored in their respective registers at their original address; if the two compared values are equal, a control signal is produced and the constant is stored but the corresponding accumulator register is reset to zero.
