Title: Crane for raising longitudinal bodies, foundation for such a crane and method for raising of longitudinal bodies by means of such a crane
Inventor: OLESEN JOHN THOMAS
IPC: F03D1/00
Filed: 1995-08-15
Abstract: A crane adapted for the erection of elongated bodies, preferably wind turbines, is attached to the same foundation which is used for the wind turbine. The crane comprises a jib which may be displaced forwards and backwards. The cap and the blades of the wind turbine are thereby hoisted to the top of the wind turbine tower once this has been erected. The crane is mounted on the same foundation which serves as foundation for the wind turbine once that has been erected. Bearing pedestals for seating the jib and anchoring straps for the attachment of double acting lifting and lowering devices are connected to the foundation, this foundation being additionally provided with an anchoring base for the wind turbine tower. The crane is of particular advantage for the erection of wind turbines in regions where it is difficult and costly to bring in a mobile crane for the erection of tall wind turbines or in case it is difficult to use a stationary crane in view of the anchoring and the support required for such cranes. Floating or wheeled mobile cranes need a large counterweight while stationary cranes according to the prior art require a solid anchoring at a great distance from the wind turbine foundation and put great demands to the steadiness of the support.

Title: Method and computer program product for interconnecting software drivers in kernel mode
Inventor: O'ROURKE THOMAS J
IPC: G06F9/46
Filed: 1997-06-19
Abstract: A method and computer program product are presented that overcome the inefficiencies in user mode processing of multimedia data by allowing an application running as a user mode process simply to start and connect multiple blocks of kernel mode functionality in the form of drivers or filters (separate logical blocks of driver executable code). Once the kernel mode filters are set up and connected, the user mode application need not be active until notified by the filters. Such notification may occur at the end of processing or at any relevant event chosen by the application as part of the filter initiation and set up. Furthermore, a user mode application may query a kernel mode filter or driver of its capabilities and requirements so that it may properly make the connections between the different filters chained together to process a stream of data and request appropriate notifications. These connection may represent actual driver to driver data exchange, or remote connections. In one exemplary embodiment, property, method, and event sets define compliant filters and native operating system I/O constructs such as file objects are used to define the instances of connection "pins" that are interconnected by the third party user mode application.

Inventor: JONES RAYMOND H
IPC: C08G59/20
Filed: 1996-02-06
Abstract: The epoxidation of alkyds containing anhydrides or diacids with cycloaliphatic unsaturation results in epoxy resins which cure rapidly in UV light to produce uniform films without the use of flow modifiers. The fatty acid portion of the alkyd functions as an internal plasticizer. Crosslinking occurs through oxirane rings in both the anhydride and fatty acid moieties of the alkyd to produce hard, but not brittle films. Excellent water resistance is obtained without thermal post curing.
Patent CA-2211137-A1 (CA)
Title: Transmission of voice-frequency signals in a mobile telephone system
Inventor: VIRTANEN ANU
IPC: H04B7/26
Filed: 1996-04-02
Abstract: According to the invention, when detecting the same DTMF signal at the transmitting end, successive DTMF frames relating to this signal are established. These frames are modified SID frames, and individual linking information (Order, Start, Duration) is added to each frame in addition to DTMF signal frequency pair information. This linking information indicates the duration of the DTMF signal from the first detection time period of the first modified SID frame to the frame concerned, including said frame. The individual linking information thus interlinks successive DTMF frames (frames 1- 4) relating to the same DTMF signal. At the receiving end, in receiving DTMF frames, it is calculated at each error-free frame how long the DTMF  signal has been received or should have been received. Only when the individual linking information of a received frame indicates that the duration of the DTMF signal is longer than the threshold value, for instance 40 ms, the DTMF signal indicated by the frequency pair information of the received frames is generated to a subscriber station. During the waiting period, background noise is generated.

Title: Method and structure for controlling the energizing of an ink jet printhead in a value dispensing device such as a postage meter
Inventor: MOH SUNGWON R
IPC: B41J2/045
Filed: 1997-08-05
Abstract: A method for controlling energizing of an ink jet printhead includes the steps of generating encoder pulses to a motor to activate the motor to move the printhead at a desired speed over a recording medium; generating and sending fire pulses at a fire pulse frequency from an ASIC to an ink jet printhead driver chip to selectively energize ink jet printhead nozzles to eject drops of ink onto the recording medium based on a predetermine relationship between an expected encoder pulse frequency and the fire pulse frequency; compensating for variations in the speed of the ink jet printhead movement caused by variations in the encoder pulse frequency by using the ASIC for continuously comparing the encoder pulse frequency to the fire pulse frequency and for adjusting the fire pulse frequency based upon the variations to the encoder pulse frequency to maintain the predetermined relationship thereby synchronizing the ink jet printhead movement with the energizing of the printhead nozzles.
