Abstract: An apparatus for modifying an exhaust stream of a diesel engine is provided. The apparatus includes a muffler arrangement having an exhaust inlet and an exhaust outlet in construct and arrange for sound attenuation therein. The apparatus also includes a catalytic converter arrangement positioned within the muffler arrangement between the exhaust inlet and exhaust outlet. During operation, the exhaust flow is directed both through the muffler arrangement and the catalytic converter arrangement, to advantage.

Abstract: A negative film supplying device for successively supplying a plurality of negative films to a printing device including: a guide path connected to a negative film guide path of the printing device; a negative film holding member for holding superposed negative films, including guide portions and a base portion interposed between the guide portions, both side portions of the negative films being interposed between the guide portions, and as opposing surfaces of the guide portions move away from the base portion, the opposing surfaces are inclined in directions of approaching each other, and a length of the base portion between said guide portions is smaller than a width of the negative film so that the negative films are curved into convex shapes in the negative film holding member; moving means for moving the negative film holding member by rotating the negative film holding member between a guiding position, at which the base portion of the negative film holding member is disposed on the guide path, and a w

Abstract: A photographic data recording mechanism in a camera includes a data illumination lamp, a first timing circuit actuated in response to the camera shutter release member for energizing the lamp for a set time interval and a second timing circuit also actuated in response to the shutter release member for applying a control signal subsequent to the lamp energizing time interval to a control circuit of shutter releasing electromagnet to release the shutter. The second timing circuit is adjustable to vary the time of application of the control signal and in an alternative structure the lamp energizing circuit may be disabled and the control signal applied is immediate response to the actuation of the release member. A single electromagnet may function to sequentially release the leading or trailing shutter members or separate electromagnets may be employed.
