Title: Gondola car structure
Inventor: FORBES JAMES W
IPC: B61D9/00
Filed: 2008-07-22
Abstract: A gondola car has a body for lading carried on an underframe. The underfra me includes a center sill and cross-bearers. The car has deep side beams having top chords, side sills, and side sheets. The lower portion of the car includes tubs that seat between the cross- bearers. The car may have an internal volume of more than 8000 cu. ft. The c ar may have rotary dump claw sockets. The car has opposed internal and external stiffene rs aligned at the longitudinal stations of the cross-bearers. The internal stiffeners may be triangular cantilevers extending upwardly inside the side sheets. The side sheet lies intermediate the stiffeners and their flanges. The top chords may be wider in cross-section than the side sills. The side sills may define torque tubes that co-operate with the sidewall stiffeners and the top chords to resist lateral deflection.

Patent CA-2639059-A1 (CA)
Inventor: YOUSSEF YOUNES
IPC: F16L25/08
Filed: 2008-08-22
Abstract: An axially tensioned pipe joint for joining two pipes is disclosed. The pipe joint comprises a first PVC pipe having an outer surface. The pipe joint also comprises a second PVC pipe having a bell end which fits onto the spigot end. The bell end has a plurality of angularly-spaced-apart holes extending radially through the bell end. A set of radial fasteners can be inserted into the holes so as to engage the outer surface of the spigot end to prevent relative axial movement of the first pipe with respect to the second pipe. The radial fasteners have a surface containing a hard material which is harder than the material of the second pipe and roughen the holes during insertion thereby creating a friction fit resisting removal of the radial fasteners. The pipe joint can be used for horizontal direction drilling.

Title: System and method for producing a tangible object
Inventor: BOOT RONALDUS JACOBUS JOHANNES
IPC: B29C67/00
Filed: 2007-07-06
Abstract: A system for producing a tangible object. The system has a space which can be filled with a fluid. A reference platform at least partially defines at least one side of the space. The system further has a phase-transformer which can form a layer of the object by selectively transforming the fluid into a solid in a predetermined area of the space.

Patent CA-2659642-A1 (CA)
Title: Non-viewable service identification for an interactive program guide
Inventor: GUMMADI SRINIVAS
IPC: H04N5/445
Filed: 2007-07-30
Abstract: The present invention is directed towards enabling systems and methods for providing an identifier that displays which channels are not viewable according to a services package authorization. More specifically, a digital host communications terminal (DHCT) receives a package authorization and stores the authorization in memory. Upon display of an interactive program guide (IPG), a processor retrieves the authorization from memory and updates the IPG. The IPG then identifies which channels are not authorized, and subsequently not viewable, by placing an identifier next to each non-authorized, or non-viewable, channel. In this manner, the subscriber knows which channels are not viewable by the IPG as opposed to selecting a non-authorized channel and receiving a message displayed indicating the selected channel is not viewable.

Abstract: A removable protective cover for a hockey skate boot, the cover having a hard but flexible protective shell with an open bottom and heel, and heel-cupping sidewall portions that flex apart diagonally to apply the cover to the boot and to grip portions of the boot heel under tension when released. The shell floats above the surface of the boot on spaced pads secured to the underside of the shell, the pads protecting side- foot, ankle, and instep portions of the foot, while still allowing the boot-laces to be adjusted while the protective cover is installed on the boot. The shell is preferably slotted on the instep to improve flexibility. The initial tensioned fit of the cover on the boot frees the user's hands from having to stabilize the cover while adjusting supplemental fasteners such as straps.

Filed: 2007-11-13
Abstract: An improved compression scheme for compressing an ECDSA signature is provided. The scheme substitutes the integer s in a signature (r, s) by a smaller value c. The value c is derived from s and another value d, d being small enough such that c is smaller than s. The compressed signature (r, c) is verified by computing a value using r and e, e being a hash of a message m, and using this value with a value R recovered from r to derive the value d. The value s can then be recovered and the full signature then recovered and verified.
