  • Patent number: 4458137
    Abstract: An air data sensor device, such as a pitot, total air temperature sensor, etc., includes an elongated probe having a sensor therein for sensing air flow parameters and a strut for positioning the probe in a desired position on an air vehicle. To avoid ice build-up on the device causing erroneous sensing of air flow parameters a substantially constant wattage electric resistive heater is provided in the probe for deicing. A PTC (positive temperature coefficient) resistive heater is disposed in the support at a location thermally isolated from the probe heater but in thermally conductive relationship to the external surface of the support. The PTC heater is connected in series with the probe heater and continuously varies heater power in response to the rate of heat dissipation at the external surface of the sensor device thereby preventing burn-out of the probe heater and erosion of the probe.

  • Patent number: 4456355
    Abstract: A processor for processing undeveloped photographic film discs mounted on a spindle assembly has a conveyor to intermittently convey the spindle assembly from a first end to a second end of the processor along a generally horizontal conveyor path. The spindle assembly is conveyed to a plurality of processing stations along the conveyor path, with each processing station having a processing tank. During processing, the processing tanks move between an upward process position and a downward dump and transport position. A fluid dispenser at each processing station dispenses processing fluid to the processing tank at that processing station when a spindle assembly is positioned at that processing station. A spindle sensor at the first end of the processor provides a signal indicative of the presence of the spindle assembly in the processor. The operations of the conveyor, processing tank movement and fluid dispensers are controlled by a control apparatus as a function of the spindle sensor signal.

  • Patent number: 4455077
    Abstract: A processor for processing undeveloped photographic film discs mounted on a spindle assembly has a conveyor to intermittently convey the spindle assembly along a generally horizontal conveyor path. The spindle assembly is conveyed to a plurality of processing stations on the conveyor path, with each processing station having a processing tank. During processing, the processing tanks pivot between an upward process position and a downward dump/transport position. In their upward process position, selected processing tanks are filled with processing fluids. When the spindle assembly is positioned at one of the selected processing tanks and that tank is in its upward process position and filled with processing fluid, portions of the film discs on the spindle assembly are contacted by the procesing fluid. The spindle and discs are then rotated to uniformly contact the photographic images on the film discs with the processing solution.

  • Patent number: 4441273
    Abstract: A resilient ferrule cover for joining tapered tubular sections of a fishing rod wherein the ferrule cover is slid over a male ferrule portion with one end of the ferrule cover abutting a female ferrule while covering an exposed portion of the male ferrule and the other end of the ferrule cover abuts a chamfered transition between the male ferrule and its supporting rod segment. After the ferrule is repeatedly assembled, wear of the parts increases, and the ferrule cover, since it is flexible, rides up over the portion of the rod to which the male ferrule is attached, assuring a continued firm ferrule junction while covering the exposed ferrule portion.

  • Patent number: 4436008
    Abstract: A photographic film cutter for cutting film segments from a web of photographic film includes a knife located along a web advancement path, a splice sensor located upstream from the knife, and a notch sensor located between the knife and the splice sensor. A stepper motor moves the web along the path in fixed length steps. A step counter counts the steps to determine the length that the web has advanced since the web was cut by the knife. When a splice is detected by the splice sensor, a maximum feed switch determines, based upon the count of the step counter, whether the distance from a leading cut edge to the splice sensor is greater than or equal to a predetermined maximum distance. If the length is less than the maximum, the web is advanced until a portion of the web adjacent the splice is positioned at the knife, and the web is cut. If the length from the cut edge to the splice is greater than the predetermined maximum length, an additional cut is made.
