Title: Coating compositions comprising a blend of an ethylene vinyl acetate and a fatty acid and emulsions
Inventor: BROWN NICHOLAS
IPC: C09K23/00
Filed: 1989-10-20
Granted: 1999-11-02
Abstract: Coating compositions based on ethylene vinyl actetate polymers have improved compatibility with solvents (especially with aliphatic hydrocarbon solvents) hydrocarbon oils, and mineral waxes by blending the EVA with a fatty acid and heating at or above the melting point of the EVA. Furthermore the resultant blends are much more easily emulsified in the presence of cations than blends which have not been processed with the fatty acids. Typically the starting material for the improved product of this invention is a composition comprising a blend of an EVA polymer and a fatty acid which is miscible in all proportions with mineral spirits at 25°C or forms a solution at a level 5% of fatty acid in mineral spirits, such as coconut or palm fatty acids. Also disclosed is that the addition of a salt of an amine acetic acid in sufficient quantity to an acidified salt of zirconium (for example EDTA and zirconium acetate) forms a novel emulsifying agent, and this emulsifying system is used advantageously with the described EVA/fatty acid blends.

Title: Color balanced image detector system
Inventor: SMYTH WILLIAM K
IPC: H04N1/46
Filed: 1990-02-05
Granted: 1999-12-14
Abstract: An imaging system for producing multicolor images of a scanned subject includes a plurality of detector assemblies. Each of the detector assemblies is sensitive to a specific color. Typically, red, green, and blue detector assemblies are employed for converting images in the primary colors to the desired output image. Each detector assembly includes multiple rows of CCD detector elements positioned in registration with each other for a two-dimensional array of the detectors. Pixels of the subject are viewed repetitively by the successive detectors of the column to provide for an integrated detector signal.      The number of detector elements in each column is varied in accordance with the color sensed by each assembly to provide for greater integration of low-intensity portions of the spectrum. This compensates the output image for variations in filter attenuation, lamp illumination, and CCD sensitivity as a function of light wavelength. The mode of compensation preserves a high signal-to-noise ratio.

Title: Determining propositional logic theorems by applying values and rules to triplets that are generated from a boolean formula
Inventor: STALMARCK GUNNAR MARTIN NATANA
IPC: G06F17/21
Filed: 1990-06-12
Granted: 1998-05-05
Abstract: The invention relates to a method and apparatus for theorem checking with the intention in so-called tautology checks of establishing whether or not all possible attributions of the truth values (0 and 1) to variables in a boolean formula render the formula true.  The problem of known techniques is that checking of the truth content is effected against all variables in an original formula, which requires many calculations to be made and which is highly time-consuming. According to the invention, an original formula is divided into part-expressions, so-called triplets, each corresponding to a part-formula of the original formula, whereafter logic 0:s and 1:s are instantiated (allotted) to variables in the triplets for the purpose of checking the truth content.  The check is thus made against triplets instead of against all variables in the original formula, therewith greatly reducing the number of calculations necessary and providing a considerable saving in time. Apparatus for carrying out the method includes a sequence unit for controlling the calculation sequency, a generator G for generating sequences of ordered variables, a permanent unit P for storing triplets, a plurality of arithmetical units, evaluators (E), and an analyzer A operative to analyze the result obtain from all calculations

Title: Sampling rate converter for signals having a non-integer sampling ratio
Inventor: FUJITA TADAO
IPC: H04N9/79
Filed: 1991-02-19
Granted: 2000-08-08
Abstract: In a sampling rate converter which converts a sampling frequency of digital signals sampled at a first sampling frequency into a second sampling frequency, output clocks corresponding to the second sampling frequency are counted in a cyclic fashion from an initial value to a maximum value based on periodicity of the first and second sampling frequencies. Coefficient addresses are generated in accordance to the resulting count value and a coefficient correction value in accordance with a number of counts of the maximum value and the periodicity of the first and second sampling frequencies, the number of the maximum value which is a number of times of counting to the maximum value. The sampling frequency of digital signals sampled at the first sampling frequency is thus converted into the second sampling frequency with a simple construction of counting to the maximum value in accordance to the periodicity of the sampling frequencies.

Title: Thermal inter-cooler
Inventor: NIVENS JERRY W
IPC: F25B41/42
Filed: 1990-01-23
Granted: 1998-08-11
Abstract: A non-restrictive, constant pressure refrigerant recycling and cooling unit (2) that interrupts the normal refrigerant cycle to permit a lower temperature liquid to enter the expansion device (5), and thus provide a lower temperature, and therefore a lower pressure gas for delivery to the inlet side (8) of the compressor (9), which acts to reduce the energy requirement and cost to operate the compressor. This reduction in pressure and temperature also results in lower operating costs and lower maintenance costs and utilizes less refrigerant quantity requirements. A key factor in attaining the above advantages is the construction of the thermal inter-cooler that is so made that no restrictions are specifically inserted in the inter-cooler system, and that direct physical contact exists between the metal compressor inlet suction line (22) and the metal (Cu) refrigerant hot line (24) for optimum heat transfer, and pressure reduction throughout the system.
