Patent CA-2180189-A1 (CA)
Title: Variable length coded data transmission device
Inventor: ADACHI SATORU
IPC: H04N7/52
Filed: 1996-06-28
Abstract: If a variable length code is caused to have a pseudo fixed length and transmitted in that condition, possible adverse effects due to out-of-synchronization attributable to code errors can be prevented, but it becomes difficult to enjoy this advantage in case an object to be fixed in length includes a block or blocks of variable length codes whose bit length is remarkably long. An object of the present invention is to obviate such a disadvantage as just mentioned. That is, for the transmission of variable length coded data blocks, a threshold arithmetic calculation circuit (9) obtains a threshold from an average of the bit lengths of the variable length coded data blocks for each group of such block., and the judgment circuit (10) makes a judgment as to whether or not those variable length coded data blocks have bit lengths exceeding the threshold of the block group to which such data blocksbelong. Then, a block divider circuit 11 divides the variable length coded data blocks having bit lengths exceeding the threshold into blocks having small bit lengths. Each block thus obtained is fixedly equalized in bit length to an average length level and in that condition.

Title: Pot-shaped permanent filter cartridge
Inventor: SCHAMBERG STEFAN
IPC: A47J31/06
Filed: 1995-03-02
Abstract: The invention is directed to a cup-shaped permanent filter element (25) for a domestic espresso maker, which receives the espresso grounds in a brewing chamber (28). The cup-shaped permanent filter element (25) has at its bottom a sieve-type filter base plate (1) provided with filter perforations (4), and is insertable into a filter basket holder (15) from which the espresso beverage is allowed to be discharged through the filter perforations (4). The cup-shaped permanent filter element (25) includes a supporting plate (2) mounted downstream of the filter base plate (1) as seen when looking in the direction of flow (A) of the espresso beverage, the supporting plate combining with the filter base plate (1) to form a pressure chamber (8) for the purpose of improving the production of crema. The espresso beverage is required to flow through the pressure chamber (8) before it is allowed to exit on the filter basket holder (15), with the generation of pressure in the pressure chamber (8) being effected by a means (11) mounted on the pressure chamber outlet and operating to increase the flow resistance. The pressure chamber (8) and the permanent filter element (25) are firmly connected with each other mechanically. The means (11) for the generation of pressure is comprised of one or several apertures whose overall cross-section is sufficiently small relative to the overall cross-section of the filter perforations (4) in the filter base plate (1) of the permanent filter element (25) to produce a pressure drop in the aperture(s) (11) sufficient for the production of crema. This results in a one-piece construction of the permanent filter element (25) which affords ease of handling and with which good crema results are obtained.

Title: Performance monitor for electric vehicle
Inventor: IMPULLITTI JOSEPH F
IPC: G01R19/00
Filed: 1995-12-07
Abstract: A system and method for monitoring usage of current immediately available from the traction batteries of an electric vehicle includes a means for generating a signal representative of the current being drawn from the batteries; a means for generating a signal representative of the maximum current available from the batteries for immediate use; and a means responsive to the drawn-current signal and the maximum-available-current signal for generating a usage signal representing the ratio of drawn current to maximum-available current.  A display, such as an analog meter responsive to the usage signal and calibrated from zero-percent to one-hundred-percent available current usage, displays the transitory current usage as a percentage of maximum-available current.  Where the batteries supply current to both the vehicle's traction motors and noncritical electrical components, a relay responsive to the usage signal sheds the noncritical component's load from the batteries when current usage rises above a given level.

Inventor: NAGL GARY J
IPC: C01B17/05
Filed: 1995-09-18
Abstract: A liquid separator system for separating molten sulfur from liquid redox solution or reslurry water. The system includes a vessel with a top part and a bottom part. The vessel has a larger diameter at the top part than at the bottom part, and the cross section of the vessel downwardly decreases from the top part to the bottom part of the vessel. The system also includes an inlet for introducing a redox solution or reslurry water and molten sulfur, which is denser than redox solution or reslurry water, into the vessel. An outlet near the bottom part of the vessel allows a flow of the molten sulfur from the vessel. An interface control structure senses an interface level between the redox solution or reslurry water and the molten sulfur, and the interface control structure controls the flow of molten sulfur from the outlet. The interface control structure is adjusted to optimally alter the vertical height of the interface level within the vessel so that the residence time of the molten sulfur in the vessel does not decrease as the sulfur production throughput decreases, and so that the interface area of the molten sulfur and the redox solution is reduced as the sulfur throughput decreases.

Title: Exfoliated layered materials and nanocomposites comprising said exfoliated layered materials having water-insoluble oligomers or polymers adhered thereto
Inventor: SERRANO FERNANDO
IPC: C01B33/44
Filed: 1997-07-28
Abstract: A phyllosilicate material is exfoliated by admixture of the phyllosilicate with water, and a solvent for a water-insoluble oligomer or polymer that is sorbed or electrostatically bonded to the inner surfaces of the phyllosilicate platelets after exfoliation of the phyllosilicate. Intercalation and exfoliation can be achieved via contact of the phyllosilicate with an organic solvent and water to electrostatically bond one or more polar moieties from the organic solvent to a metal cation on the platelet inner surfaces, so that after evaporation of the water used for intercalation of the organic solvent between phyllosilicate platelets, the platelets do not then collapse together, but remain exfoliated. After exfoliation of the phyllosilicate, the exfoliated platelets are contacted with a polymer/carrier composition that includes a water-insoluble polymer or water-insoluble oligomer, and a solvent for the water-insoluble polymer or oligomer. After exfoliating the phyllosilicate and prior to polymer contact, the individual phyllosilicate platelets are contacted with the polymer/carrier composition to sorb the water-insoluble polymer or water-insoluble oligomer onto one or both surfaces of the exfoliated phyllosilicate platelets and drive off the adhered solvent.

Abstract: A method and apparatus for creating multiple branch wells from a parent well is disclosed. According to a first embodiment of the invention a multiple branching sub is provided for placement at a branching node of a well. Such sub includes a branching chamber and a plurality of branching outlet members. The outlet members, during construction of the branching sub, have previously been distorted into oblong shapes so that all of the branching outlet members fit within an imaginary cylinder which is coaxial with and substantially the same radius as the branching chamber. According to one embodiment, the distorted outlet members are characterized by an outer convex shape. In another embodiment, the distorted outlet members are characterized by an outer concave shape when in a retracted state. After deployment of the branching sub via a parent casing in the well, a forming tool is lowered to the interior of the sub. The outlet members are extended outwardly by the forming tool and simultaneously formed into substantially round tubes.  Next, each outlet member is plugged with cement, after which each branch well is drilled through a respective outlet member. If desired, each branch may be lined with casing and sealed to a branching outlet by means of a casing hanger. A manifold placed in the branching chamber controls the production of each branch well to the parent well. According to a second embodiment of the invention, a pressure resistant branching sub is provided which may be installed in series with a casing string, and the associated equipment used for the installation operation and intervention of a well. The branching sub includes a main pipe and a lateral outlet.
