Title: Production of methanol
Inventor: VAN VUUREN DAVID S
IPC: C07C29/86
Filed: 1990-11-30
Abstract: ABSTRACT OF THE DISCLOSURE A process for producing methanol comprises reacting hydrogen with carbon monoxide and/or carbon dioxide to form a methanol containing product. This product is contacted with a liquid organic absorbent having between 3 and 16 carbon atoms and which is chemically inert with respect to the product, thereby to absorb methanol into the absorbent. Methanol is recovered from the methanol-rich absorbent. The mass proportion of absorbent to methanol recovered is less than 10 mass units absorbent for each mass unit of methanol.
Patent CA-2031780-A1 (CA)
Inventor: SALOOM THOMAS J
IPC: B29C48/07
Filed: 1990-12-07
Abstract: A new and useful process for producing a plastic article (e.g., vinyl siding) with an accent color pattern incorporated therein, and a specially formed accent color pellet which is useful in such a process. The process contemplates extruding a plastic product from a base compound formed of powder sized particles and specially formed accent color pellets. The accent color pellets are alloyed masses of resins and pigment which are larger than the powder particles of the base compound, and have a higher deflection temperature than the base compound. The alloyed pellets are designed with controlled heat deflection characteristics. During the extrusion process, the accent color pellets begin to soften and disperse later than the base compound, and cause restricted dispersion of the accent color into the base compound, thereby producing accent color streaks in the resulting extrudate. The process is particularly suited for producing a simulated woodgrain or streaking effect in plastic (e.g., vinyl) siding.

Title: Steel post shore, or prop, for supporting of formwork in constructing buildings
Inventor: LAMBERTUS DE LEEUW PETRUS J
IPC: E04G11/48
Filed: 1991-03-25
Abstract: For supporting of formwork in constructing buildings, use is made of steel post shores (props) having a pin with recessed areas thereon. When the prop has to be brought from the loaded to the unloaded position, such pin is changed of position in the prop so as to allow the inner tube to be lowered within the outer tube of the prop. The invention provides a new pin-design such that after assembling the prop it can be clearly seen wether the pin finds itself in the correct position or not. For that purpose, use is made of a pin having a recess and a flattened portion; by axial displacement of ache pin this portion rests on a ring or on an inner tube under changing its angular position, which is well visible for the user.      Alternativily a cylindrical pin may have two cams resting on a ring; by axially displacing this pin it will rotate over 90° and the inner tube will be lowered in the outer tube, which position is clearly visible for the user.

The screen has an outer fluid permeable wall 4, an inner permeable wall 5 and an annular layer of pre-packed particulate material 6 therebetween.  Fluid can flow radially inwardly through the screen into the annual space 7 between the screen inner wall and the washpipe outer wall.  Washpipe sections are coupled by a subsection of pipe 8.  The ends of the coupling are joined to respective ends of sections of washpipe by conventional means.  Screen sections are joined together by a stinger. Conventional joining means may be used.  The stinger has a portion of its length necked down, and this portion has a polished sealing surface 9 which can provide a contact seal to a pair of appropriately sized pipe rams (not shown). Internally of the stinger, at the same level as the external sealing surface, there is an internal polished sealing surface.  An annular seal 10 carried on a sub-unit 8 forms a contact seal on this internal sealing surface.  Thus, fluid from the annular space 7 cannot pass by the seal 10.  A method for deployment of a BHA as described above is disclosed.  m e BHA may be deployed in an oil/gas well under pressure.

Patent CA-2051416-A1 (CA)
Title: Ring laser
Inventor: HANNA DAVID C
IPC: H01S3/083
Filed: 1990-04-11
Abstract: A ring laser (10) incorporates a laser rod (R) with end faces (R1, R2). The first face (R1) is coated for high reflectivity at the laser wavelength and the second (R2) for high transmission at this wavelength. The first face (R1) provides one cavity end mirror, and a concave mirror (M1) spaced apart from the rod (R) provides the other. A rhombic prism (P) between the rod (R) and mirror (M1) defines differing (figure of eight) forward and return paths (14 to 17, 18 to 21) for cavity radiation passing from one end mirror (R1 or M1) to the other and returning. The prism (P) presents Brewster's angle refracting surfaces. The second rod face (R2) is tilted to produce an optical path in two planes. A magnetic field (B) along the rod axis (Ra) produces Faraday rotation of polarization. This counteracts rotation arising from non-coplanar optics for one direction of propagation around the laser cavity (10) but not the other. This produces unidirectional laser action.
