Filed: 1991-02-18
Abstract: ABSTRACT OF THE DISCLOSURE     A structure for connecting a screw shaft and a drive cable in a shoulder belt positional adjustment device of a seatbelt, comprises a first joint coupled to one or connecting end of the screw shaft, and a second joint coupled to one or connecting end of the drive cable.  The connecting end of each of the screw shaft and the drive cable is noncircular in section.  The first joint includes a cylindrical rotatable member and a cylindrical holder into which the rotatable member is inserted for rotation about its own axis. The rotatable member has  a bore to receive the connecting end of the screw shaft.  The second joint includes a cylindrical coupling member having an inner hole of a noncicular section, a cylindrical holder having a coupling member holding bore into which the coupling member is inserted for rotation about its own axis, a stopper extending radially from the inner periphery of the holder between the coupling member holding bore and a recess to prevent release of the coupling member from the holder, and a spring disposed within the coupling member holding bore to urge the coupling member against the stopper.     The connecting end of the drive cable is inserted into the inner hole of the coupling member of the second joint.  The coupling member and the rotatable member are enagaged with each other.  One of the holder of the first joint and the holder of the second joint has an engaging element which entends in a direction toward the other holder.  The other holder has a receiving element with which the engaging element is engaged to prevent the first and second joints from being separated from each other.

IPC: G06V10/422

Abstract: A body of data is operated upon hierarchically in such a way that, at one or more levels of the hierarchy, the number of aggregative data items produced is not substantially less than the number produced at the preceding level. The body of data can be an image, so that each aggregative data item indicates an attribute of a distinct image region. Such attributes include presence of a single connected component or properties of a component such as width, orientation and curvature. A class of abstract computation structures, called exhaustive hierarchical structures, is introduced in which such dense or exhaustive hierarchical aggregative data analysis processes can be embedded. The embedding of exhaustive hierarchical analysis in a computation structure of this class is analogous, and in some implementations similar in processing efficiency, to the embedding of conventional hierarchical aggregative data analysis processes in tree structures. The exhaustive hierarchical embedding introduced analyzes extensively overlapping regions in a manner that places minimum demands on the number of communication links, memory resources, and computing power of the individual processing units. Specifically, the embedding scheme is a general scheme for mapping locations in an array into nodes at two adjacent levels of a binary exhaustive hierarchical structure. The scheme establishes positional relations in the array that correspond to parent-child relations at a given level in the exhaustive hierarchical computing structure; these positional relations are uniform power-of-two offsets in each array dimension at a given hierarchical level. Consequently, this exhaustive hierarchical analysis can be implemented efficiently using conventional communication techniques, including hypercube and grid techniques, on a massively parallel processor. To minimize memory requirements, hierarchical results at each location can be encoded across all levels.

Title: Back pressure regulating valve for ultra high pressures
Inventor: ESLINGER DAVID M
IPC: G05D16/10
Filed: 1991-09-13
Abstract: Abstract of the Disclosure A back pressure regulating valve for ultra high pressures.          The valve is designed for use in throttling ultra high pressure pumps, such as those used in fluid jetting systems.  The valve has an elongated tapered poppet which fits in an elongated tapered seat such that an elongated, annular tapered flow path is defined therebetween. The flow path preferably has a length greater than a diameter of the poppet, such as approximately ten times the maximum diameter.  Also in the preferred embodiment, a minimum annular tapered flow path is defined between the seat and poppet even when the poppet is in an unactuated position.          Biasing is provided by a gas filled pressure chamber acting on an actuator piston.  The piston at least partially defines a damping chamber, and an orifice is provided between the damping chamber and the pressure chamber so that movement of the piston is damped as it is moved in a direction tending to reduce the volume of the pressure chamber.
Patent CA-2052118-A1 (CA)
Inventor: SMITH DANIEL R
IPC: F02M35/022
Filed: 1991-09-24
Abstract: An engine air precleaner which is efficient at both low and high engine speeds as described.  The precleaner has two air flow designs incorporated within it:  one for a lower velocity of air flow and one for a high velocity of air flow.  The dual air flow design is accomplished by an outer tubular sleeve member and an inner tubular sleeve member attached to an engine air intake stack.  At low engine speeds, the air flow passes into the precleaner and through the inner tubular sleeve, causing the contaminant removal system to efficiently remove contaminants from the air.  When the engine speed is increased, a valve opens allowing air to flow through tubular sleeve.  Therefore, the  contaminant  removal system will operate substantially the same speed whether the engine is running at a lower or higher throttle.

Abstract: ABSTRACT OF THE DISCLOSURE A series of premix burners (B, C) of different sizes  are  arranged  at  the  inlet  flow  end  of  a combustion chamber (A), preferably of the form of an annular combustion chamber.   The large premix burners (B),  which  are  the main burners  of  the  combustion chamber, and the small premix burners (C), which are the pilot burners of the combustion chamber,  emerge into a front wall (10) of the combustion chamber, these premix  burners  (B,  C)  being  arranged  alternately relative to one another and at a constant distance apart.   Whereas the main burners (B) emerge directly into the front wall (10) to the combustion space, the pilot  burners  (C)  have,  downstream of  their burner length, a precombustion chamber (C1) extending as far as the front wall  (10).   Both the evaporation of a liquid fuel and the burn-out of liquid or gaseous fuels in  the  low part-load  range  of  the machine  can be decisively improved in this precombustion chamber (C1).

Title: Selectively transmissive polysulfonic hollow fiber membrane and method of manufacture thereof
Inventor: KOBAYASHI TAKUICHI
IPC: D01F6/76
Filed: 1992-03-27
Abstract: A hollow polysulfonic fiber intended for a selectively transmissive membrane contains a hydrophilic polymer which is cross-linked into a water-insoluble form (for example polyvinylpyrrolidone) and is used in the form of a hydrogel containing water. A method for the production of a membrane module consists in spinning a hollow fiber by the use of a spinning solution containing a polysulfonic resin and a hydrophilic polymer, wetting the fiber above the saturated moisture content, and then, with the wet condition maintained, subjecting the fiber to the processes of module molding and radiation induced cross-linking, these processes being performed in either order. The method provides a selectively transmissive hollow polysulfone fiber membrane which displays less elution into water and a sharp molecular weight fractionation, so as to be usable safely in the fields of medicine and foodstuffs.
