Patent CA-2263453-A1 (CA)
Inventor: UNGAR LYLE
IPC: H03M7/40
Filed: 1997-08-04
Abstract: The adaptive compression technique improves the Lempel-Ziv (LZ) technique because it reduces the required storage space (18) and transmission time with transferring data (22). Pre-filled compression dictionaries (48) are utilized to resolve prior problems with the Lempel-Ziv technique where compression software starts with an empty compression dictionary and little compression is attained until dictionary has been filled with sequences common in the data being compared. The compression dictionary (48) is pre-filled with letter sequences, words and/or phrases that are commonly found in the compressed area. They may be used in the pre-filled dictionary where they are determined by sampling text data from the same text genre. Initially, multiple pre-filled dictionaries (52) may be utilized by the software, where the most appropriate dictionary for maximum compression is identified and used to compress current data. These modifications are made to any of the known Lempel-Ziv compression techniques based on the variants detailed in 1977 and 1978 articles by Ziv and Lempel.

Title: Armor stop for metal clad cable connector
Inventor: MARIK GREGORY C
IPC: H01R9/05
Filed: 1999-03-25
Abstract: An armor stop which is removably insertable into a range taking electrical connector defining an elongate cable passageway having opposed first and second openings for terminating first-sized electrical cables of a first range of diameters in abutting engagement therein. The armor stop includes an elongate arcuate armor stop wall having opposed inner and outer surfaces. The inner surface defines a conductor receiving passageway for receiving one or more conductors of a second-sized cable having a diameter smaller than the first- sized cable. The armor stop wall includes a first end insertable into the cable passageway and has a thickness defined between the inner and outer surfaces which prevents the second-sized cables from being inserted into the conductor receiving passageway. The armor stop wall is circumferentially discontinuous about the cable received in the cable passageway so as to allow the one or more conductors received therein to pass therethrough.

Title: Method and packaging utilizing calcium cyanamide for soil treatment
Inventor: HARTMANN RICHARD O W
IPC: C05C7/00
Filed: 1997-10-20
Abstract: Processes and structures for using calcium cyanamide fertilizer in a manner to greatly enhance its most effective oil treatment form prior to its application. Dry, dusty granules and fines of calcium cyanamide are placed directly into tanks of liquid for transformation or within biodegradable bags through which water can freely flow. The bags are submerged in a tank of water. The insoluble calcium oxide and carbon components thereof remain as solid residuals within the bags. Hydrolysis occurs and the solution is biocidal and ready for immediate application. The solution can be sprayed or irrigated onto a targeted soil area with conventional dispersal equipment. The remaining non-dissolved material in the bags can be dispersed on and into the plant crop soil. Additives of other fertilizers into the above solution can be used to enhance effectiveness. When the calcium cyanamide is placed directly into the liquid, the mixture will become slurry-like.

Title: Method for the low-waste manufacture of diskoid moulded bodies containing active ingredients, and transdermal therapeutic systems containing same
Inventor: BRACHT STEFAN
IPC: A61J3/06
Filed: 1997-10-25
Abstract: The invention relates to laminate bodies or disks containing active ingredients, which are especially suitable as active ingredient reservoirs for transdermal therapeutic systems and are obtained on the basis of an oblong moulded shape whose outer surface area corresponds to the contours of the laminate bodies to be manufactured and whose cross-sectional structure corresponds to the structure of the laminate bodies, by slicing off sections at right angle to the lengthways direction of the oblong moulded body. In the simplest case, the moulded body consists of a homogeneous mass of active ingredient and has the form of a full cylinder, which is sliced perpendicular to its axis at equal intervals in such a way as to obtain identical, round, single-compartment disks. The moulded body may, however, present any other external form and internal structure; notably it may consist of a consolidated bundle of strands containing different active ingredients or active ingredient concentrations, which when divided yield disks having several compartments at one level. The "active ingredients" include not only therapeutic drugs and their precursors and activators but also any type of reagent, additive, test substance, etc.

Filed: 1998-03-23
Abstract: The invention relates to a laser-assisted measuring system for three-dimensional objects and complex surfaces. In accordance with the invention, three-dimensional objects are preferably interior areas of buildings or geological hollows with complex surfaces. The invention makes a considerable contribution to the rationalisation and improvement of precision in measuring operations of this kind. In the known pulse operation time method, the distance is measured by a laser pulse from the transmitter to the measuring point and back. A measurement fan is generated on emission of laser pulses. In accordance with the invention, the measurement tan (11) must be turned 360° step by step at a constant speed, in order to cover a three-dimensional area. In a wall, up to 200,000 measuring points can be obtained. An appropriate evaluation of the measurement data takes place so chat a 3 D wire model can be constructed.

Patent CA-2290091-A1 (CA)
Title: Vapor-liquid contact tray with two-stage downcomer
Inventor: YEOMAN NEIL
IPC: B01D3/32
Filed: 1998-05-12
Abstract: A vapor-liquid contact tray (16) is provided with an upstream downcomer (46) and a downstream downcomer (48) which form a two-stage downcomer. The discharge outlet of the upstream downcomer (46) feeds liquid into the downstream downcomer (48) to help seal the discharge outlet (58) of the downstream downcomer (48) against vapor entry at lower liquid flow rates and to allow positioning of the discharge outlet (58) above the height of the weir on the underlying tray (16). Because the upstream downcomer (46) does not discharge liquid directly onto the underlying tray deck (40), the area of the tray deck (40) underlying the upstream downcomer (46) can contain vapor flow apertures (68) to increase the active area and mass transfer efficiency of the tray (16).

Patent CA-2295109-A1 (CA)
Title: Manifold array processor
Inventor: PECHANEK GERALD G
IPC: G06F15/80
Filed: 1998-06-24
Abstract: An array processor includes processing elements arranged in clusters which are, in turn, combined in a rectangular array. Each cluster is formed of processing elements which preferably communicate with the processing elements of at least two other clusters. Additionally each inter-cluster communication path is mutually exclusive, that is, each path carries either north and west, south and east, north and east, or south and west communications. Due to the mutual exclusivity of the data paths, communications between the processing elements of each cluster may be combined in a single inter-cluster path. That is, communications from a cluster which communicates to the north and east with another cluster may be combined in one path, thus eliminating half the wiring required for the path. Additionally, the length of the longest communication path is not directly determined by the overall dimension of the array, as it is in conventional torus arrays. Rather, the longest communications path is limited only by the inter-cluster spacing. In one implementation, transpose elements of an N x N torus are combined in clusters and communicate with one another through intra-cluster communications paths. Since transpose elements have direct connections to one another, transpose operation latency is eliminated in this approach. Additionally, each PE may have a single transmit port and a single receive port. As a result, the individual PEs are decoupled from the topology of the array.
