Patent CA-2074655-A1 (CA)
Inventor: LEFEBVRE NOELLA
IPC: A61G19/00
Filed: 1992-07-24
Abstract: A manual instrument enables the user to deposit a funerary urn on the bottom of a hole dug into the soil.  It comprises an elongate member having an upper end provided with a handle.   A plate is hingedly mounted, about a first axis, on the lower end of the elongate member between an horizontal position in which the urn can be placed on the top surface of the plate and a generally vertical position in which the urn is released.  A rod has an upper end close to the handle of the elongate member and a lower end pivotally connected, about a second axis spaced apart from the first axis, to the free end of an arm secured to the plate.  To pivot the plate from the horizontal to the vertical position, the user has only to pull the upper end of the rod upwardly.  In operation, the plate is moved to the horizontal position, the urn is placed on the top surface of the plate, the elongate member is manipulated through the handle to displace the urn to the bottom of the hole, and the upper end of the rod is pulled upwardly to pivot the plate from the horizontal to the vertical position in order to release the urn and deposit it on the hole's bottom.

Title: Bridge Construction
Inventor: TERON WILLIAM
IPC: E01D21/00
Filed: 1992-09-21
Abstract: A method of constructing a bridge using a two step composite construction process. In the first step, the region to be spanned is bridged with precast prestressed concrete elements that are designed as beams and complete permanent formwork to carry the dead load of the bridge, to provide a high density concrete protective shell giving a greater degree of protection against deterioration from the elements and to provide a very high quality of finish and architectural design, to provide a complete working platform for construction, and to eliminate the need for temporary scaffolding and formwork. In the second step, additional poured in place concrete is cast into the spaces created by the precast elements and serves as beams, post-tensioned to carry the live loads of the bridge. A bridge is thus created comprised of precast elongated elements supported on abutments at the sides of the spanned region, reinforced concrete beams contained by and between the adjacent elements, and a deck supported by the beams and elongated elements.

Title: Process for low-pollutant combustion in a power station boiler
Inventor: HAUMANN JUERGEN
IPC: F23C7/00
Filed: 1992-10-26
Abstract: ABSTRACT OF THE DISCLOSURE       In a process for low-pollutant combustion in a power  station boiler  (22)  for steam generation,  at least one precombustion chamber (24) acts at the boiler itself, which precombustion chamber is operated with at least  one  burner  (25a-c).  At  least  a part  of  the primary  air  (26)  initially  flows  through  a  heat exchanger (24c), in which a caloric treatment of this air takes place to give combustion air  (26a).  This combustion air (26a) then flows into the burner (25a-c), where a mixing, and subsequent combustion with fuel (12) or with another mixture takes place. A further air stream as secondary air (27) is injected directly into the  precombustion  chamber  (24),  this  taking  place directly before the actual join of the precombustion chamber  (24)  to the boiler  (22).  Downstream of the precombustion chamber (24), a tertiary air stream (29) is fed into the boiler (22). Using this configuration, a process with double air staging is proposed,  the boiler (22) being operated with air deficiency. As a result  of  this  substoichiometric  operation  of  the boiler (22), nitrogen-containing fuel compounds can be reduced.            (Figure 1)

Title: Process for producing protein
Inventor: HASHIMOTO TAMOTSU
IPC: C12N1/21
Filed: 1991-05-10
Abstract: abstract A gene coding for a protein BBRP42 which is secreted at the initial stage of cultivation is cloned from the gene library of Bacillus brevis, then an expression unit vector containing a DNA coding for the signal peptide and a DNA coding for translation regulating signals is constructed. The process of cultivation of the host cell having a recombinant plasmid which is linked with the foreign gene at the downstream of the region coding for the signal peptide of this expression vector successfully leads to the secretion of the foreign genetic products from the host cell at the initial stage of cultivation where the proteolytic enzymes have not been secreted too much, and leads to efficient production of the foreign genetic products.

Input entering means (manually, magnetically, mechanically, electronically and the like) such imaged readable means and/ or pre-imaged data for identifying selected faces of selected markers for determined area placement on a certain publication vessel (50), regulating/controlling by identifying through such entering step the input/output directing the user to apply each marker member to a selected placement for the system.  The computer (42) data, markers (10) and publications (50) to  the system have a determined/ pre-determined associative relationship to each other.  Optionally machine means reading selected faces of selected markers for the system to determine information means contents therein the respective publication to which each marker member correspondingly represents thereon.  Imaging and/or reading information means before, during or after the markers are adheringly mounted to their respective publication vessel for which each marker is produced.

Inventor: REAGEN WILLIAM K
IPC: C08F4/46
Filed: 1993-01-19
Abstract: Improvements or modifications of earlier process for preparing chromium-containing compounds, such as, for example, chromium pyrrolides, by forming a mixture of a chromium salt, a metal amide, particularly a pyrrolide, and an electron pair donor solvent, such as, for example, an ether, and reaction with an unsaturated hydrocarbon are disclosed, including use of pyrrole or derivatives thereof as the pyrrolide and an aliphatic as the unsaturated hydrocarbon. A new process for preparing a catalyst system comprises combining a metal source, a pyrrole-containing compound and a metal alkyl without a preliminary reaction step between the metal source and the pyrrole-containing compound in the presence of an electron donor solvent. These catalyst systems and chromium-containing compounds either unsupported or supported on an inorganic oxide support, if desired functioning as a cocatalyst in combination with another polymerization catalyst, such as containing chromium or titanium, can be used to trimerize, oligomerize, and/or polymerize olefins.

IPC: D21C9/08
Filed: 1991-07-30
Abstract: The deposition of pitch on the machinery used in pulping and papermaking processes and in the final paper produced in the papermaking process is prevented by adding an effective amount of a water-soluble organotitanium compound to the aqueous system of a pulping and/or papermaking process to prevent the deposition of the pitch on the machinery and in the final paper. The addition of an effective amount of a water-soluble organotitanium compound to the aqueous system of pulping and papermaking processes also removes pitch deposits from the machinery used in the pulping and papermaking processes.

Abstract: A cable of this invention includes a core comprising a plurality of coated optical fibers and a filling composition of matter which is disposed about the fibers. Typically, the fibers and the filling material are disposed within a tubular member which is disposed within a sheath system. The sheath system includes longitudinally extending strength members and a plastic jacket. The filling composition which fills interstices in the core is one which includes an oil constituent which is a relatively high molecular weight aliphatic hydrocarbon. The aliphatic hydrocarbon is a synthetic oil such as polyalphaolefin or mineral oil. A relatively large percent by weight of an antioxidant system is used to prevent thermal oxidative degradation of the filling material as well as of materials in contact with the filling material. Advantageously, for stabilization and metal deactivation, the composition includes zinc dialkyldithiophosphate or diaryldithiophosphate. A styrene-ethylene propylene copolymer is also included in order to reduce oil separation of the filling material. A fumed silica is used to impart gel properties to the material.
