Abstract: A decorative wheel cover apparatus is disclosed for relatively inexpensively simulating the appearance of a more expensive custom wheel. A wheel cover member, having a contoured body and circular inner and outer rims which accurately simulates the appearance of a custom wheel is removably secured to an ordinary automotive wheel by a unique retention system. The retention system includes a first portion disposed along the back of the wheel cover member, and a second portion preferably adhesively bonded to the wheel directly behind the first portion, with the first and second portions being suited for releasable engagement with one another. Preferably, the first and second portions of the retention system constitute mating rings, the first ring being secured to the outer rim of the wheel cover member and having a plurality of lugs extending therefrom, and the second ring having a plurality of receptacles or slots for receiving and releasably retaining the lugs. A method of installation is included.

Abstract: An amusement shooting game for play by a plurality of players (30, 40) wherein players (30, 40) shoot at each other while avoiding being shot at is provided. The players' (30, 40) equipment includes a vest module (46) and helmet (44) for generating and transmitting a coded signal uniquely identifying each player (30, 40). Each player further utilizes a gun (50) for receiving the transmitted coded signals transmitted by players (30, 40). A processing unit (74) is responsive to the gun (50) for detecting a transmitted coded signal. Data processing devices (126, 110, 114) are utilized for counting and displaying the number of detected coded signals to provide a score for each player representing the number of players (30, 40) he has shot during the play of the game.

Abstract: In a continuous balling process, which may be the formation of green balls from iron ore, water and a binder in a balling drum as a stage in the pelletizing of iron ore, which includes a balling circuit in which undersized balls are recycled directly together with further raw material, the phenomenon known as surging is reduced by a method which involves including in the process a stage modifying the fundamental direct relationship between discharged undersize balls and those recharged, this unmodified direct relationship being the recurrence of the discharged balls identically as recharged balls after a constant time interval.

Abstract: A process for forming balls from mineral ores, particularly iron ore, in which water is added to the ore and the balls are produced in a balling drum. The surface wetness of the balls so produced is determined by apparatus which measures the intensity of light reflected from the balls in a selected direction, and the output from the measuring apparatus is used to control the addition of water to the material fed to balling drum.

Abstract: A vehicle (e.g. aircraft) head-up display system having the capability of displaying, superimposed on an observer's view of the scene outside the vehicle, symbols representing information required by an observer in the vehicle, together with a pictorial representation of the vehicle environment produced by a signal source incorporating an imaging sensor. The signal source produces an output signal of raster scan format (e.g. a television type line-by-line scan format) and output signals of the same format representing the required symbols are developed by a storage/read out arrangement which stores the symbols in response to stroke writing mode signals and reads out the stored symbols in the same raster scan format as is employed by the signal source, the raster scan outputs of the storage/read out arrangement and the signal source being combined for application to the display unit of the system.
