Abstract: An underground utility line flagger and marker having an elongated main body having an upper end and a lower-end ground penetrator, a forwardly projecting handle at the upper end at an acute angle to the main body, the ground penetrator having a marker flagstaff-engagement recess at the bottom thereof, and a foot-driven projection on the main body whereby the staff of a marker flag lying on the ground can be inserted into the ground with the flag upright by using the handle to place the engagement recess on the flagstaff and stepping on the peg.

Abstract: A depression gun pod for detachable connection to an aircraft stores suspension rack, the pod having a gun and having a gun mount providing for depression of the gun in elevation and for limited azimuth movement; the mount utilizing a plurality of planar frame-like members which are disposed in a compact configuration within the pod when the gun is in a forward firing position and which rigidly support the gun as it moves in depression and azimuth.

Abstract: A sabot fragment diverter deflects selected sabot fragments discarded by ot type ammunition in a directionally controlled manner to prevent direct fragment impact with the firing platform or impact of a deflected fragment with the projectile from which it is discarded. A fragment diverter cone which includes a deflecting surface, a fragment cutter and a barrier dam is connected to the muzzle end of a gun system by an extender cage and a mounting section.

Abstract: A device for determining the velocity, trajectory and attitude of a projele. Light beams from two perpendicular linear arrays of light emitters are incident upon corresponding linear photodetector arrays. Each light beam in the linear arrays includes an individualized characteristic to permit unique identification of each beam. Trajectory and velocity parameters are determined by identifying which detectors have an interrupted light beam and from the time interval between actuation of the arrays.

Abstract: A carpet cleaning machine wherein cleaning fluid is continuously dispensed to an in-place carpet from manually manipulatable tools and wherein dirty fluid is continuously picked up from the carpet and conveyed to a dirty fluid collecting chamber. The machine is characterized by an automatic discharge means for the dirty fluid collecting chamber whereby dirty fluid is automatically cycled out of the collecting chamber and delivered to a disposal location as required. The machine is further characterized by an automatic cleaning fluid supply system.

Abstract: A carpet cleaning machine of the portable type that is characterized by a compact frame arrangement for supporting dispensing and pick-up systems for liquid type carpet cleaners. The cleaning liquid and dirty liquid are simultaneously applied to and picked up from a carpet by means of a manually operated carpet cleaning tool. The machine is further characterized by auxiliary dirty fluid collecting means mounted on a separate wheeled auxiliary frame. The auxiliary fluid collecting means is disconnectably located in the flow of dirty fluid from the carpet cleaning tool to a main collecting means on the machine with said auxiliary collecting means being adapted to be removed from emptying without preventing continuation of the carpet cleaning operation.

Abstract: A carpet cleaning machine wherein cleaning fluid is continuously dispensed to an in-place carpet from manually manipulatble tools and wherein dirty fluid is continuously picked up from the carpet and conveyed to a dirty fluid collecting means. The machine is characterized by a plurality of individually operated tools connected to a common machine frame and common operating components mounted therein thereby providing for the simultaneous work efforts of a plurality of tool operators.
