Abstract: A fire escape window system has a fixed outer, peripheral frame set permanently into a window opening of a wall. An inner frame carrying sash units, screens, storm glass, and the like is mounted in the outer frame on a hinge axis. The inner frame pivots from a position weather-sealed across the outer frame to an open position where the opening in the outer frame is unobstructed for emergency personal egress. A latch retains the inner frame in a closed, sealed position but is quickly releasable for swinging of the inner frame to the open position. A spring may be used to bias the inner frame to move automatically to the open position upon release of the latch. A safety alarm signals upon opening of the inner frame. The latch may be electrically operated and, if so, it may be connected for opening the inner frame selectively in conjunction with a smoke or other fire detector which is activated by an emergency condition.

Abstract: An automatic device for gently recovering parts upon completion of machining operations as in an automatic lathe. Automatic lathes and other cutting machines generally drop finished parts from the machining area in the absence of custom-designed recovery devices, exposing the parts to damage by falling onto hard surfaces such as other completed parts. The present invention is useful without custom adaptation to a variety of automatic cutting machines. A cushioned shovel extends from a double-acting pneumatic or hydraulic piston beneath the part as its cutting is completed and before the part is dropped from the cutting machine. The shovel retracts and turns on the piston's axis to deposit the part onto a conveyor located away from the cutting machine. Fluid controls govern motion of the piston according to the position of a cam driven by or controlling the operation of the cutting machine.

Abstract: A water sprinkler is described for developing predetermined but variable patterns of water coverage. The sprinkler includes a plurality of pattern-defining apertures which are contoured in accordance with desired patterns of water coverage to pass varying but predetermined amounts of water as a sprinkler nozzle rotates. A sampling aperture progressively samples the outputs of selected pattern-defining apertures in synchronism with the rotation of the sprinkler nozzle so as to conform the water output of the nozzle to that of the desired pattern of water coverage.
