Abstract: During repeated cycling of alkaline manganese dioxide cells, it is critical to ensure that adequate barrier protection is formed and maintained between the anode and cathode of the cell to prevent shorts from occurring between the cathode and the anode. However, the potential also exists for anodic zinc to migrate via the absorbent separator and create a short path to the cathode. To prevent this, cells can be fabricated whereby a separator barrier is placed into the cells, a hot melt sealant is metered into the cell so that the sealant flows under the separator barrier, the separator barrier is pushed down and seated into the hot melt. The end result is a separator barrier which is sealed at the bottom of the cell and at both sides of the separator barrier and virtually eliminates shorts from developing between the electrodes.

Abstract: A method and apparatus for heating or cooling a product which includes a plurality of tapered ducts in a cabinet above and below a turntable to form streams which are directed toward the product. Spent air is drawn through intake openings in return ducts in the cabinet. Temperature controlled gas is delivered at an angle through an array of openings adjacent opposite edges of an opening through which a product is loaded on the turntable in a loading zone to cause most of the heated air to be drawn to return duct openings and to maintain internal pressure in the baking zone in the cabinet to prevent ingress and egress of air through the loading opening. Orifices are formed in a circular array of rings such that the sum of the areas of orifices in each ring spaced from the axis about which the turntable rotates is substantially equal.

Abstract: An orifice fitting for measuring the flow of gas through a pipeline in which the orifice fitting has a body including a pair of opposing body plates that define a body chamber.          Passing through both body plates is an aligned flow passage for attachment to a gas pipeline.   One of the body plates includes an access opening that is selectively covered and sealed by a hatch.   A carrier having a carrier chamber is movably positioned within the body chamber so that the carrier chamber can be selectively aligned with the flow passage or the access opening.  Removably positioned within the carrier chamber  is  an  orifice  disk  having  an  orifice  of  a predetermined size through which gas can flow when the carrier chamber is aligned with the flow passage.  The carrier chamber is sealed from the body chamber by seal rings positioned on opposing sides of the carrier and biased against the body plates.  When the carrier chamber is aligned with the access opening,  an  annular  injection groove positioned  on each sealing ring communicates with respective injection passages extending through the  body plates,  thereby permitting  a sealant to be injected into the injection groove for emergency sealing of the carrier chamber.  The orifice fitting further includes a valve assembly extending through one of body plates and communicating with the carrier chamber.  Extending from the valve assembly is a venting passage that permits the gas from the carrier chamber to be vented to the atmosphere at a distance from the valve assembly.

Abstract: A three dimensional imaging radar system and method for generating and processing radar information to produce a three dimensional image of objects viewed by the system. The system is designed to create three dimensional images of physical objects at relatively short range, up to a distance of about 1000 feet. The radar system comprises a servo controlled antenna system, wherein the servo system provides azimuth and elevation pointing angle output signals. Two radar transmitters provide radar signals in two different radar bands that are selectively transmitted by the antenna system as a radar beam. A radar receiver preprocesses radar return signals reflected from targets. A digital signal processor is provided that processes the radar return signals from targets and which embodies system improvements comprising a Fouriertransform processor, a coherent integrator that provides low pass and high pass filter-ing to reduce noise, a detector comprising a digital Pythagorean processor that converts the radar return signals into amplitude values for each range bin, a noncoherent integra-tor, and an adaptive threshold comparator. A buffer memory is is provided that has a predetermined number of range cells that store the amplitude of the radar return signal at each range. A digital scan converter comprising a three dimensional coordinate converter converts the azimuth and elevation pointing angle signals into x, y and z addresses of radar signals that are stored in the buffer memory. A computer selectively controls the transmission of the radar signals each radar system, adaptively controls the movement of the antenna system using the servo system, and processes the x, y and z addresses of radar signals stored in the buffer memory to produce a three dimensional image for display on a monitor. A digital sweep linearizer is provided which produces a highly accurate linear sweep signal that drives a voltage tuned oscillator. The coher-ent integrator provides "noise reducing" low pass or high pass filtering of the signals prior to detection. The bandpass of the filters in the coherent integrator is controlled by the digital signal processor.

Abstract: An apparatus to form a part of an agricultural planting implement is provided to simplify and enhance its function.          There are tanks provided for supplying material such as seed and fertilizer to be planted.  The seed and fertilizer are elevated from the tanks by a separate flexible positive feeding conveyor to two or more respective chambers where a single wheel or cylinder in each chamber meters the material conveyed to the chamber.  The metered material then enters several guide tubes where it is gravity fed to a furrow made in the ground by the implement.  Each of the chambers includes an expandable portion to indicate whether or not they are functioning properly.  When an implement with folding side wings are used an air assist and/or a shaking clamp may be applied to the gravity fed guide tubes to ensure proper placement of the materials.

Abstract: A method of arbitrary image resolution conversion takes an original print ready image at a first resolution and orientation and simulates printing of that image by creating a representation of a page at a particular resolution and orientation using a suitable spot model for the reconstruction function. The image is then filtered with a low pass filter and sampled with an aperture that corresponds to the desired output. The image data, which may be definable at several bits per pixel, is then made print-ready by reducing the number of bits defining each pixel to a valid output state. The reduction step is accomplished through error diffusion methods that maintain the local area gray density level. The filtering step reduces moire in the converted image.
