Abstract: TEXTURED VENETIAN BLIND AND METHOD OF MAKING THE SAME A polyvinyl chloride venetian blind is provided which has a number of corrugated, translucent slats. The slats have short, preferably chopped staple fibers in their composition, which fibers are of any suitable colored or uncolored, natural or synthetic material, preferably cotton, wool, flax, and nylon, or mixtures thereof, in sufficient amount uniformly distributed throughout the body and surface thereof so that they give the slats a permanent sand or granite textured appearance and preferably feel, whereby the venetian blind has more natural and aesthetic appeal. The slats are formed by an extrusion process utilizing a mixture of polyvinyl chloride, titanium dioxide, plasticizer, tribasic lead sulfate, stearic acid, and the staple fibers which have an average length of less than about 2mm. and preferably are chopped to give them sharp ends. If desired, the surfaces of the slats can be smooth or polished.

Patent CA-2085375-A1 (CA)
Inventor: FREDETTE MAURICE C J
IPC: C01D5/02
Filed: 1991-06-20
Abstract: Chlorine dioxide is produced at high efficiency by reduction of sodium chlorate with methanol in an aqueous acid reaction medium at a total acid normality below 7 with the reaction medium being at its boiling point while a subatmospheric pressure is applied thereto and having a chlorate concentration of at least about 2.0 molar. By employing such conditions, the tendency is eliminated for the reaction to be subject to white-outs in the absence of added chloride ion. In this way, the chlorine content of product aqueous chlorine dioxide solution arising from this source is eliminated.

IPC: C12N15/09
Filed: 1991-07-01
Abstract: Nucleic acid sequences and DNA vectors useful for the production of CD4 chimeric proteins, as well as other heterologous proteins, in Streptomyces are disclosed. The nucleic acid sequences of the invention comprise the coding sequence for the signal peptide of the Streptomyces longisporus tyrosine inhibitor (LTI) gene operatively linked with a propeptide sequence consisting essentially of an amino acid sequence coding for from one to about 6 amino acids, the sequence of said amino acids selected to result in the formation in Streptomyces of a protein product having a homogeneous amino terminus after processing to remove said signal peptide formed on the protein product during synthesis of the protein product. In an alternative embodiment of the invention, the propeptide is omitted and the LTI signal peptide is operatively linked with a nucleic acid sequence coding for a heterologous protein which has been modified to code for the sequence lys-ala-at the 3' end. The invention also provides cells transformed with the nucleic acid sequences or vectors of the invention, and methods of using the nucleic acid sequences and vectors of the invention to produce heterologous proteins in Streptomyces.

Title: Anti-web adhering contour surface for a photographic processing apparatus
Inventor: BARTELL ROGER E
IPC: G03D3/13
Filed: 1993-02-09
Abstract: Textured surfaces on respective walls of racks and tanks of photographic processing apparatus reduce the frictional forces between the photosensitive material leading edge surfaces and the walls of the racks and tanks. The processing solution flows through fissures in the textured surfaces, thereby providing a solution bearing layer between the photosensitive material and the textured surfaces. This allows a greater photosensitive material leading edge impact angle with the textured walls which allows the photosensitive material to change direction unimpeded.

Abstract: Abstract of the Disclosure Electric motor stators can have coils wound on their poles which coils have more turns than the poles could normally support by augmenting the pole with additional structures to support the added coil turns.  The additional structures can be only temporarily associated with the stator, e.g., by adding them to the winding shrouds which are customarily applied to the stator during winding.  Alternatively these additional structures can be permanent but non-magnetic portion of the stator, e.g., by adding them to the terminal board members of the stator.

Title: Production method for corn with enhanced quality grain traits
Inventor: BERGQUIST RICHARD R
IPC: A01H1/02
Filed: 1991-10-11
Abstract: A novel method of producing corn grain with enhanced quality traits including high oil content has been developed. Through pollination of male-sterile hybrid corn plants by nonisogenic corn plants possessing genes which control the expression of enhanced quality grain traits, grain is obtained possessing such traits much higher than would be expected for self- or cross-pollination. This method can be practiced by farmers using currently accepted farming practices to directly obtain high yields of high-oil corn grain, high-protein corn grain, and other valuable grain for animal feed and other products.

Title: Formation of microstructures using a preformed photoresist sheet
Inventor: GUCKEL HENRY
IPC: H01L21/027
Filed: 1993-11-12
Abstract: In the formation of microstructures, a preformed sheet of photoresist, such as polymethylmethacrylate (PMMA), which is strain free, may be milled down before or after adherence to a substrate to a desired thickness. The photoresist is patterned by exposure through a mask to radiation, such as X-rays, and developed using a developer to remove the photoresist material which has been rendered susceptible to the developer. Micrometal structures may be formed by electroplating metal into the areas from which the photoresist has been removed. The photoresist itself may form useful microstructures, and can be removed from the substrate by utilizing a release layer between the substrate and the preformed sheet which can be removed by a remover which does not affect the photoresist. Multiple layers of patterned photoresist can be built up to allow complex three dimensional microstructures to be formed.

Title: A solid fuel ramjet engine for, e.g., a spin-stabilized projectile
Inventor: GUNNERS NILS-ERIK
IPC: F02K7/10
Filed: 1992-06-15
Abstract: With the intention of achieving more stable combustion conditions in solid-fuel ramjets, and particularly in the case of ramjets with spinning application, it is proposed that the inner surface of the ramjet fuel element (8) is provided with raised surfaces, or lands (14), preferably formed from the fuel element material.  In one preferred embodiment, the lands (14) are straight and extend parallel with the longitudinal axis of the fuel element and have the same length as the fuel element. The tangential component of the rotating gasflow generated by rotation, forces the peripheral part of the gasflow to pass over these raised surfaces (14), thereby generating standing, stabilizing vortices downstream of the raised surfaces.
