Abstract: New methods and new katharometer apparatus for the measurement of thermal conductivity of gases are provided. The apparatus employs a single katharometer element (10), that is maintained at a constant operating temperature. If the element (10) temperature changes, changing its resistance, owing to passage of a gas with a different thermal characteristic, an amplifier (32) changes the power supplied to the katharometer element (10) to restore it to the predetermined temperature, the amplifier (32) output being a measure of the gas thermal conductivity. Operation of the apparatus is therefore independent of the resistance/temperature characteristic of the element (10) and is relatively insensitive to ambient temperature changes. Preferably a thermistor is employed as the katharometer element (10). Various operating circuits for the katharometer are disclosed. The invention also provides new operating methods for katharometers to reduce the sensitivity of measurement to thermal leakage and temperture changes to the katharometer body, and to permit the comparison of voltages across a series connected katharometer element (10) and a resistor (18) at a common reference point.

Abstract: A mold for hollow injection molding has an inlet (10) for admitting a fluid (930) into the molten resin when injected to form an interior hollow in the molded product. The inlet is opened and closed by retraction and advancement of a movable pin (121) having at least a portion to fill the inlet (10) and close it. When the inlet is closed, while the resin is being injected, the pin (121) has a portion which projects out of the inlet (10) into the space (2) where the resin is injected. When the inlet is opened, the retraction of the pin (121) leaves a short passageway in the injected resin leading from the fluid inlet (10) for flow thereinto of the hollow-forming fluid. Preferably, the pin is stepped with an inlet-closing large rear portion and a smaller projecting forward portion which is located in and has an annular clearance with the inlet when it is open. The pin may be detachably connected to a movable plunger (12), operated by fluid (50) or spring pressure, to enable replacement by pins of different lengths, sizes, etc.

Abstract: An encryption system and method based on the mathematics of Chaos theory, which provides protection of data from unauthorized modification and use during its storage and transmission. At its core are nonlinear equations which exhibits random, noise-like properties, given certain parameter values. When iterated, a periodic sequence is produced with an extremely long cycle length. A domain transformation process is then used to convert the floating-point iterates into binary form for summation with the digital data to be protected. The result is an encrypted message that cannot be modified, replaced, or understood by anyone other than the intended party. The use of Chaos theory in combination with the domain transformation process results in an easily implemented cryptographic system with extremely robust cryptographic properties. The concepts of the present invention also lend themselves well to either hardware or software implementations. The cryptographic system of the present invention may be employed to encrypt and decrypt sensitive information, to authenticate data and video links, or similar applications. It can also be used to provide a simple hash function for the secure storage of passwords in a computer system. Its simplicity, requiring only floating-point operations at its core, allows a lower cost and higher performance product with cryptographic security equivalent to conventional cryptographic systems.

Abstract: A method is described for enabling leak detection of an underground storage tank surrounded by a water table. The method begins by sealing a test probe in the tank, the test probe having an elongated substantially hollow core with first and second ends, a housing for receiving the second end of the hollow tube and being vented to the fluid product, a low temperature coefficient medium supported in the substantially hollow core of the elongated tube, and a liquid seal supported in the housing between the medium and the fluid product. The method continues by then establishing and maintaining a pressure equilibrium between the hollow core of the test probe and the head space. An inert gas such as nitrogen is then introduced into the head space to overpressurize the head space by an amount sufficient to reestablish a leak at any break in the storage tank despite presence of the water table surrounding the storage tank. Once the tank contents are stabilized, the precision leak test is performed.

Abstract: In a solid image pickup device wherein a plurality of microlenses (28) are provided on a substrate (12) having light receiving portions (16), in opposition to the light receiving portions (16) so that incident light can converge onto the light receiving portions (16), the microlenses (28) are covered with a transparent resin layer (44) having a refractive index smaller than that of the microlenses (28). Therefore, the solid image pickup device (60), even when packaged in a molded body (72) made of a resin having a refractive index similar to that of the microlenses, can offer a good sensitivity because the microlenses (28) can effectively operate as condenser lenses due to the resin layer (44) between the molded body (72) and the microlenses (28).
