Title: Removing Waste Ink from Capping Station
Inventor: DIETL STEVEN J
IPC: B41J2/165
Filed: 1994-06-06
Abstract: A process and apparatus for removing waste ink from a capping station on a low cost integral capping, priming and wiping station for a thermal ink jet printer. In particular, the prime operation is repeated so that the scanning carriage (containing the ink jet printhead) travels past the capping position which breaks the vacuum seal and causes waste ink in the cap volume to be released into the pump chamber, thus cleaning the cap volume of excess ink. The additional prime cycle does not remove ink from printhead orifices because the scanning carriage travels away from the capping position as vacuum is applied.
Patent CA-2125239-A1 (CA)
Title: Network service provisioning
Inventor: BORG KENNETH A
IPC: H04M3/42
Filed: 1994-06-06
Abstract: A network service provision system and method for advanced intelligent networks uses a hierarchy of three structures: service building blocks, features, and services. Services are defined in terms of features. Features are defined in terms of building blocks. The building blocks are simple software defined procedures requiring a set of parameters. The features are decision graphs built from building blocks using data. Services are then built using a subscriber profile from combinations of service building blocks and feature decision graphs together with the subscriber profile and support data. As new services can be defined using data, loading new services can be accomplished in service control points without interrupting services already active.

Patent CA-2128060-A1 (CA)
Title: Pipe Coupling
Inventor: BLOSE THOMAS L
IPC: F16L15/04
Filed: 1994-07-14
Abstract: A pipe  coupling or connection comprises  a  female coupling component and a mating male coupling component.  Each component is matingly threaded for coupling engagement, and each is provided with an adjacent frusto-conical sealing surface.  The sealing surface is provided with a controlled surface roughness, viz. very shallow fine surface variations, preferably formed as microgrooves at a pitch small relative to the pitch of the threads.  The slope of the frusto-conical surface of the sealing surface of the male component is slightly mismatched with that of the sealing surface of the female component to simulate the bearing force vs. axial distance characteristic of shrunk-fit circular cylindrical sealing surfaces.  The mismatch enables the sealing pressure to be above a design minimum throughout the entire sealing area yet higher at each end of the sealing area.          As the coupling is assembled, thread interference in the vicinity of  the sealing surface lags the occurrence of  interference between the sealing surfaces.  Load threads are provided with negatively inclined load flank faces.   The slope of the load thread pitch line of the male element is slightly steeper than the slope of the load thread pitch line of the female element.          Load thread interference values and tolerances are selected to enable the shrunk-fit cylindrical sealing surface simulation to be met over the range of tolerances provided.  The envelope of the range of curves of interference vs.  distance along the effective pin sealing surface area has a positive slope.  The effective sealing area is at least about one-third and preferably at least about half of the available sealing area.

IPC: H04W36/08
Filed: 1994-07-14
Abstract: ABSTRACT OF THE DISCLOSURE:           In a TDMA mobile communication network in which a mobile station (11) moves across radio zones at an initial state (1), a current channel through a first station (BASE A) of base stations is switched at the mobile station to a fresh channel through a second station (BASE B) during progress of communication between the mobile station and a mobile exchange station (41) by using two time slots in each TDMA frame for up and down communication signals, respectively, at an earlier state (5).  At a later state (6), only one of the two time slots is used for the up and the down communication signals.  Channel switching is possible between two mobile stations through the exchange station and at the exchange station rather than at the mobile station.

Patent CA-2138919-A1 (CA)
Inventor: MIYAUCHI HIROSHI
IPC: H04L9/10
Filed: 1994-12-22
Abstract: Electronic signature apparatus and method provide an electronic signature that can be created only by a signer, but cannot be used for other than the signature object document to be processed, and that can be verified and authenicated as an image. Since the verified result is an image, such as a print of a seal and a signature, the verifier can easily verify the validity of the image. In addition, since a signature image and a signature object document may separately be processed, combined, and decomposited upon decryption, they can effectively be used for a printed signature.

Title: Olefin metathesis
Inventor: KELLY JAMES
IPC: C07C11/08
Filed: 1995-07-05
Abstract: The present invention is a process for the production of a mixed C4 olefinic stream comprising primarily isobutene and butene-1, and propylene, said process comprising subjecting a mixed olefin feedstock comprising C5 olefins and ethylene to metathesis in the presence of a catalyst at a temperature in the range from about -20°C to 200°C and subjecting the resulting metathesis product to fractionation to recover the mixed C4 stream and propylene resulting therefrom. The production of MTBE or tertiary butyl alcohol or iso-butene sulphate from this C4 stream gives rise to substantially pure butene-1 as a by-product.
