Title: A method to provide a software package and a provider station and a user station realising the method and a basis software package
Inventor: PEETERS JOHAN
IPC: G06F9/445
Filed: 1998-03-10
Abstract: The method is used to provide a software package for installation in a user station (US) without revealing the contents of the software package. The method includes the steps of encoding a readable source version (PACK.SOURCE) of the software package following a predefined encoding algorithm thereby generating an encoded software package (PACK.ENC) and delivering the encoded software package (PACK.ENC) from a provider station (PS) to the user station. In order to install the encoded software package (PACK.ENC) at the user station (US) the method further includes the step of providing, either together with the encoded software package (PACK.ENC) or separately, a basis software package (BASIS) for combined decoding and compiling of the encoded software package (PACK.ENC). The basis software package (BASIS) includes software to perform the combined decoding and compiling thereby generating a compiled software package (PACK.COMP).

Patent CA-2230042-A1 (CA)
Inventor: MACCARIO FLORIANO A
IPC: F16L1/11
Filed: 1998-02-19
Abstract: A method of achieving improved delectability of pipe, duct or conduit buried below the surface of the earth involves providing the pipe, duct or conduit with a plurality of very small high energy permanent magnetic elements spaced apart along the length thereof.  Preferably the elements will be positioned within a groove, or grooves, formed in the external surface of the pipe, duct or conduit, and they will be covered by a protective tape to avoid inadvertent mechanical removal and to avoid contamination once the pipe, duct or conduit has been buried. For plastic pipe there should be a projection extending inwardly of the interior of the pipe adjacent the groove so as to ensure that the wall thickness of the pipe is maintained.  A pipe carrying a single longitudinally extending groove should be positioned in the ground with the groove uppermost for maximum flow of gaseous material within the pipe. If the pipe is provided with a pair of diametrically opposed grooves then the pipe should be buried with the grooves generally parallel to the surface of the ground. A pipe, duct or conduit provided with the magnetic elements of the present invention, which can measure in the order of 1.2 mm thick, 6.5 mm wide, and 10 cm long, is easily detectable by a standard gradiometer at a depth of 1.2 m.

Title: Coriolis effect mass flowmeter using a single rotor having a flexible sensing element
Inventor: VAN CLEVE CRAIG BRAINERD
IPC: G01F1/82
Filed: 1996-11-12
Abstract: A Coriolis flowmeter having a rotor assembly positioned within a housing and having center axis of rotation. The rotor asssembly has a plurality of flow channels, each of which extends from the outer periphery of said rotor assembly to a center recess of said rotor assembly. An inlet extends material through the flow channels to an outlet of the flowmeter. The rotor assembly rotates about the center axis of rotation as the material passes through the flow channels. Coriolis forces generated by the material flowing and the concurrent rotation of the rotor assembly cause a flexure element comprising a part of the rotor assembly to assume an arcuate offset. Strain gauges or sensing coils and magnets generate output signals indicative of the magnitude of the angular offset and the mass flow rate of the flowing material. A motor connected to the rotor assembly can rotate the rotor assembly at an increased velocity to operate the flowmeter as a pump that generates output signals indicative of the pump throughput.
