摘要： Apparatus for treating a web with treatment fluid comprises a two part housing defining a recess for receiving the web and a fluid distribution system for supplying treatment fluid to the recess. The fluid distribution system comprises a series of passages connected in a whiffletree configuration for dividing and subdividing the treatment fluid to supply treatment fluid to the recess at a plurality of locations across the recess to uniformly treat the web with the treatment fluid. In another embodiment the processor comprises a pair of plates defining a recess for receiving a web. The plates have at least one pair of elongated liquid injection openings extending transversely of the recess on opposite sides of the web respectively in juxtaposed relationship for injecting liquid into the recess. The plates further include at least one pair of elongated evacuation openings extending transversely of the recess on opposite sides of the web respectively in juxtaposed relationship for evacuating liquid from the recess. A whiffletree liquid distribution system is associated with each of the openings to supply liquid to the injection openings and to evacuate liquid from the evacuation openings.

摘要： Apparatus for drying a web comprises a pair of spaced parallel plates defining a channel there between of predetermined thickness and length for receiving the web. The plates are provided with juxtaposed elongated openings respectively for injecting drying air into the channel on opposite sides of the web. Air under pressure is supplied to the openings to establish a high velocity laminar flow of air from the openings in opposite directions along the surface of the web. Air is evacuated from the channel on opposite sides of the web at a predetermined distance from said openings to maintain the heat transfer rate in the air higher than the heat transfer rate in the web.

摘要： Apparatus for treating a web with a fluid comprises means defining an elongated channel for receiving the web. The fluid is injected into the channel on opposite sides of the web at one or more injection sites. Fluid is evacuated from the channel on opposite sides of the web at one or more evacuation sites. Each injection site is located between two evacuation sites and spaced therefrom such that fluid will flow in opposite directions from the injection site to the adjacent evacuation sites with laminar flow and be evacuated from the channel when the boundary layer of the fluid reaches a predetermined thickness.

摘要： An autofocus camera includes an electronic flash and a piezoelectric focus motor that are both powered by a moderately high voltage power supply. The camera includes an automatic focus detector that senses a scene and produces a focus signal representing the required focus adjustment for the scene. A focus motor drive circuit responsive to the focus signal supplies a controlled amount of power from the power supply to the piezoelectric focus motor to drive a movable lens element to effect the required focus adjustment.

摘要： A control apparatus is disclosed for discriminating between light emitted from sources having respectively different flicker ratios (the ratio of the brightest and the dimmest intensities during a given time period). A photocell produces a voltage having a DC component proportional to the log of the average intensity of incident light and an AC component proportional to the log of the flicker ratio. After the DC component is removed, the AC component is amplified and may be applied to a filter-moving control means to cause appropriate color-correcting filters to be interposed between the scene and photosensitive material, as for instance in a camera. Alternatively, the AC component may control a marking mechanism to encode the film with a mark readable during the subsequent printing process.

摘要： A web treatment apparatus comprises a means defining a channel through which the web is transported. Treatment fluid is injected into the channel on opposite sides of the web at spaced injection sites and evacuated from the channel on opposite sides of the web at spaced evacuation sites. The injection sites and evacuation sites alternate so that injected fluid is evacuated from adjacent evacuation sites. The streams of evacuated fluid are combined such that streams varying in flow path length and chemical depletion are sequentially mixed together in an ordered sequence prior to reinjection into the chemicals. In one embodiment means are also provided for sequentially dividing the fluid flow from a recirculation pump into fluid streams that are supplied to the injection sites.
