Patent EP-0321299-A2 (EP)
Inventor: CODY IAN ALFRED
IPC: B01J23/40
Filed: 1988-12-16
Abstract: An improved wax isomerization catalyst is described which is a hydrogenation metal on halogenated refractory metal oxide support catalyst characterized in that the catalyst is prepared by depositing the hydrogenation metal on the refractory metal oxide support followed by fluoriding using a low pH fluorine source such as aqueous HF. Thereafter the catalyst is crushed to expose inner surfaces, the crushed catalyst being sieved to remove fines, the catalyst charge having an average particle diameter of 1/32 inch (0.79375 mm) and smaller, preferably between 1/64 to 1/32" (0.3969 to 0.7938 mm). Alternatively, the catalyst is made by depositing a hydrogenation metal on a refractory metal support, crushing the material to a particle size of 1/32 inch (0.79375 mm) and smaller across the largest cross-­sectional dimension and fluoriding said material using acidic fluorine source such as HF. Following sizing the sized catalyst is activated by heating in a hydrogen atmosphere. 
     Isomerization using this "sized" catalyst is marked by the production of an isomerized dewaxed oil product having unexpectedly high VI and superior levels of selective conversion of wax to liquid isomerized product.

Abstract: In the manufacture of optical devices such as, e.g., optical communications assemblies and optical gyroscopes, low-loss substrate-supported optical waveguides are desired. Such waveguides can be obtained by patterning a layer of deposited waveguide material and, in the interest of minimizing loss as may be due to processing-induced surface roughness, waveguides as patterned preferably undergo a heat treatment which results in surface smoothing and in rounding of the waveguides cross section. Furthermore, in the interest of avoiding re-entrant corners between substrate and waveguide, a wetting layer may be applied to the waveguide prior to heat treatment.

Abstract: A control system and methodology used for defining and executing parametric test sequences using automated test equipment for semiconductor wafer testing. The control system is divided into components which separate fixed, reusable information from information which is specific to particular tests. One component (20) contains reference data which describes the configuration of the wafer (15) being tested as well as specifications for the tests to be carried out. Another component (22) contains a set of measurement algorithms that describe individual tests to be performed on generic types of devices (32) or parametric test structures. Execution of a test is carried out by a general test program (24) which retrieves stored reference and test definition information and supplies it to the measurement algorithms to enable them to perform measurements on specific devices in the user specified sequence.

Abstract: An optical transducer system for use with an optical transducer of the kind which produces a wavelength multiplexed optical output signal comprises a broadband optical source, and a tunable filter in the form of a Fabry-Perot interferometer connected to receive a broadband optical signal from the source. The interferometer is repeatedly swept through its pass band by a control signal of triangular or sawtooth waveform, producing a swept wavelength optical signal for application to the transducer. In one embodiment, the optical output signal from the transducer is compared with the output signal from the interferometer to decode it, while in another embodiment, a control loop maintains the output amplitude (intensity) of the broadband source substantially constant over the range of wavelengths used by the transducer, enabling a reference channel provided in the transducer to be used for decoding purposes.

Abstract: A photoimageable composition of the negative acting type which includes a binder polymer which contains carboxyl groups is provided with a metal chelate in which the coordination number of the metal is 2 or higher. When the photoimageable composition is coated as a layer on a dry film, the metal chelate reacts with the carboxyl groups of the polymer, releasing a metal ion which bridges carboxyl groups of two or more polymer molecules. This bridging reduces cold flow of the photoimageable composition layer of the dry film.
