Abstract: A training aid of the simulator type for use in teaching the techniques of adjusting the cylinders of a multi-color rotary web printing press to achieve acceptable registration between the successive impressions forming a printed color page. Four superimposed positive colored film transparencies mounted on a light box provide facsimiles of the red, yellow, blue and black images successively printed on a web; and all but the black transparency are carried separately on adjustable frames which are movable to effectively simulate the endwise (button-to-gear), the circumferential and the cocking adjustments of the plate cylinders of a rotary press. Endwise and circumferential simulating movements are by electric motors each of which is controlled for forward and reverse drive by a manual switch that is identical with the switch on a press cylinder adjustment control panel, and the manual cocking control precisely simulates that for a press cylinder.

Additionally, the circuit means includes various alternate forms of control dependent upon pressure in a part of the system or on speed of a mechanism utilizing the pumped fluid to establish conditions wherein fluid delivered by the system is at either a desired flow rate or within a range of flow rates at different pressures.

Abstract: A fuel injection pump has a barrel with a central bore communicating through axially staggered fuel inlet and outlet ports with an outer peripheral recess in the barrel which, in cooperation with a fuel pump housing, forms an annular fuel receiving cavity about the pump barrel. A relatively large fuel reservoir in the housing communicates with the annular cavity through fuel inlet and outlet conduits in the housing, the outlet conduit being aligned with the outlet port in the pump barrel. A plunger having a scroll surface at one end is rotatably and reciprocably received in the pump barrel bore, and the scroll surface is selectively registrable with the fuel ports. A pulse shield of hardened material is disposed within the fuel reservoir in alignment with the fuel outlet conduit to deflect fuel from the outlet conduit into the main portion of the reservoir and to prevent erosion of the housing surfaces.
