Patent CA-2476749-A1 (CA)
Title: Aircraft
Inventor: WOBBEN ALOYS
IPC: B66F19/00
Filed: 2003-03-05
Abstract: The present invention concerns an aircraft having a plurality of lifting and thrust rotors, with an electric motor and an inverter for each motor.   In order to provide an aircraft having a greater payload, connecting bars are provided between the motors. In that respect the invention is based on the realisation that, if such connecting bars are arranged in the manner of a latticework, they can provide a light but nonetheless stable structure for the aircraft, and that structure can carry correspondingly greater loads.

Title: Supplemental restraint for auto-rack railroad car restraint system
Inventor: PEACH WALTER J
IPC: B60P3/077
Filed: 2004-08-17
Abstract: A supplemental restraint for a primary vehicle restraint system for an auto-rack railroad car which reduces or eliminates movement of the vehicle in the auto-rack railroad car. The supplemental restraint is adapted to be positioned on a grating between the tire of the vehicle and the primary restraint. One embodiment of the supplemental restraint includes a body and an expander connected to the body. After the primary restraint is locked in place on the grating, the expander of the supplemental restraint is expanded. The expansion causes a more secure engagement between the tire and the primary restraint. This causes a high level of engagement between the tire and the primary restraint system indirectly through the supplemental restraint. The supplemental restraint also maintains a higher contact area on the tire regardless of the position of the primary restraint.

Title: Entering text into an electronic communications device
Inventor: ZHANG DANIEL YALIN
IPC: G06F3/041
Filed: 2003-03-05
Abstract: In a method of entering text into an electronic communications device by mea ns of a keypad having a number of keys, each key representing a plural~ity of letters and/or phonetic symbols, entered text is displayed on a display on t he device. Possible phonetic syllables corresponding to an activated key sequen ce are generated. These are compared with a stored vocabulary comprising syllables and corresponding characters occurring in a given lan~guage. Those stored syllables and corresponding characters that match the possible syllables are pre-selected; and a number of these are presented in a separat e first graphical object (11) arranged predominantly on the display. Character s corresponding to one of the syllables in the first object are simul~taneousl y presented in a second graphical object (21). Thus there is pro~vided a way o f entering text with characters having a phonetic representation by means of keys representing a plurality of letters or phonetic symbols, which is easie r to use even in the case where a phonetic syllable corre~sponds to several characters.

Title: Packer retriever
Inventor: STREATER JAMES R
IPC: E21B29/00
Filed: 2003-05-06
Abstract: A packer retriever (100) having a grapple body (127) rotatably and slideably coupled to a mandrel (102) directly attached to a milling tool (140) can engage a packer (or extension thereof) (142) having a substantially smooth I.D. in a wellbore while the packer is milled. The mandrel rotates in a central opening through the grapple body (127). The grapple body does not rotate when released from teeth(134) of a nut(112) on the mandrel and can remain engaged to the packer ( or the extension) as milling proceeds. The mandrel includes a specially designed shoulder(116) and the grapple body includes a specially designed bearing (108), both casehardened, which allow the mandrel to rotate constantly while reducing die effects of wear. The packer retriever remains in the engaged position to prevent the packer from falling if it breaks loose while milling. The packer retriever can transfer torque to the packer and can be engaged and released multiple times.
