Patent CA-2149447-A1 (CA)
Title: Donahue jiffy roller dumper and extend-a-box
Inventor: DONAHUE DAVID A
IPC: B60P1/52
Filed: 1995-05-16
Abstract: Running gear consisting of a track and carriage is installed on the bed of a pick-up truck or on a flat bed trailer in such a manner as to allow a hopper or cargo box to be attached to it. The hopper rides on the carriage assembly which runs along two parallel channel rails attached to the truck bed. The hopper and its cargo are pulled out manually until a point of equilibrium is reached. As the hopper and load are pulled out past the point of equilibrium, a break in the top of the channel rails allows the rear axle on the carriage to rise up out of the track, and because the carriage and hopper are now over balanced, the hopper tilts up thereby dumping the load behind the truck. The carriage may also be used as a truck bed extender by removing the hopper from the carriage assembly and extending the carriage to its maximum position and locking it in place. This would then support loads longer than the length of the bed of the truck.

IPC: H04L9/00
Filed: 1994-03-28
Abstract: Methods and apparatus for encoding compressed data streams efficiently, and methods and apparatus for decoding the encrypted data streams are disclosed. In an encoder (10'), an incoming data stream is fed to a Huffman coding block (10) that performs data compression. The output codewords are fed to a forward error correction block (30). The data blocks are fed to an error insertion block (32), which inserts a one-bit error in each data block. The parity data is fed to a first encryption block (34) that produces encrypted parity data. The output of the error insertion block (32), the encrypted parity data, and a synchronization word output by a sync generator (50) are fed to a multiplexer (48). A seed generator block (36) generates random numbers for use by the first encryption block (34) as seeds for encryption the parity data. A multisession key register (40) stores a multisession key employed as a seed in a second encryption block (38) to encrypt the random number seed. A secret serial number (SSN) read from a database (46) and stored in an SSN register (44) is employed by a third encryption block (42) as a seed for encrypting the multisession key. A decoder (14') receives the multiplex data and recovers the original data.

Patent CA-2168245-A1 (CA)
Title: Polynucleotide decoys that inhibit mhc-ii expression and uses thereof
Inventor: HUNT C ANTHONY
IPC: A61K35/12
Filed: 1994-07-29
Abstract: The invention is directed to a newly discovered class of polynucleotide decoys that is capable of competitively inhibiting the binding of transcription factors to the X-box sequence. This binding is necessary for the expression of MHC-II genes. The invention is also directed to methods of preparing these polynucleotide decoys, and methods of use thereof. In particular, we have identified a class of polynucleotide decoys that mimic the X-Box of MHC-II and competitively bind the MHC-II transcription factor RF-X, resulting in the modulation of MHC-II antigen expression. Thus, the invention can be used to inhibit the expression of HLA molecules on the surface of donor cells or organs, in order to render them invisible to the host's immune system, or in methods of treating an individual with an autoimmune disease characterized by dysfunctional expression of an MHC class II antigen. Further, because of the role of RF-X in the expression of several viral proteins, the polynucleotide decoys of the invention can be used in methods of treating an individual infected with hepatitis B virus, or cytomegalovirus.
Patent CA-2169399-A1 (CA)
Title: Analytical halftone dot construction for a hyperacuity printer
Inventor: CURRY DOUGLAS N
IPC: B41J2/44
Filed: 1996-02-13
Abstract: A printing device (10) is commanded to print a reference set of intensity values from almost white or highlight regions through almost dark or shadow regions. A measuring device (12) measures the actual outputted printer intensity levels from the printing device (10). An interpolator (14) interpolates the printer intensity levels into a best fit smooth curve plotted against the reference set of intensity levels which produces a non-linear function. A mapping means and converter (24a, 24b) calculate a set of fractional intensity values and densities which produce a linear function when mapped with the printer intensity levels. A dot area parameter calculator (28) calculates a set of dot parameters defining a configuration of a halftone dot required to fill an area within the halftone cell corresponding to each intensity level. For each position of each halftone cell, a measurement processor (30) determines a distance between a current scan position (a,b) and a nearest edge defined by the dot parameters. A gray value calculator (50) calculates a gray value for the current scan position based on the distance and angle to the nearest edge of the dot. The halftone dot is completed when a gray value is calculated for each position within the halftone cell. The gray values are stored in a look-up table (26). When a new image is to be printed, the intensity values are input (54) and the scan position is indexed (52) through all available scan positions to generate corresponding addresses in the look-up table (26), causing the corresponding gray values to be output serially in order for use by a laser diode controller (56) of a laser printer or analogous controllers in other types of printers.

Title: Helicopter integrated fire and flight control having a pre-launch and post-launch maneuver director
Inventor: FOWLER DONALD W
IPC: F41G9/00
Filed: 1994-12-02
Abstract: An integrated fire and flight control (IFFC) system determines a ballistic firing solution based on the position of targets relative to a helicopter and also based on the type of weapons to be fired. An elevation command is determined based on the required change in helicopter attitude to achieve the ballistic firing solutin that, combined with the estimated time required to perform the aim and release of weapons, provides an estimate of deceleration and velocity loss that will occur. A forward acceleration and velocity profile is determined based on the desire to make a symmetrical maneuver sequence involving a nose down acceleration to achieve the acceleration and velocity profile that will be canceled by the subsequent deceleration and velocity loss during the pitch up maneuver to the ballistic firing solution. The forward acceleration and velocity profile is used to provide a pilot with a forward acceleration command that directs the pilot to fly a nose down attitude until the required forward acceleration and velocity profile is achieved. Alternatively, the acceleration profile is coupled to a flight control wherein a pre-launch maneuver feedforward command signal is summed with a side arm controller control command signal as the primary input to a rotor mixing function and a pre-launch commanded rate signal is summed with a side arm controller commanded rate signal to provide the primary input to an automatic flight control system, to thereby automatically control the aircraft to assume an attitude necessary to achieve the desired forward acceleration and velocity profile. A terminal phase maneuver is calculated to thereby return the aircraft to the previous attitude, velocity hold, hover hold or position hold condition prior to commencement of the pre-launch maneuver.

Abstract: "On the World Wide Web, the Hyper-Text Markup Language (HTML) is used to create HTML documents.  Special text items called Tags are included in an HTML document, by writers, to specify the format of the HTML document.  Client computers retieve HTML documents from centralized Server computers that in turn retieve the HTML Documents from their data store.  Once the client has retrieved a document, a software program running on the Client is responsible for parsing the tags and presenting the formatted document to the user. In this invention, a new protocol called Server Tags is defined as an extension to the HTML language.  Server Tags are special text items place in an HTML Document, by writers, that are parsed by the software programs running on the Server prior to returning the document to the requesting client.   Server Tags instruct these programs to perform text pre-formatting.  Because  Server Tags are processed by the software programs running on the Server, they provide a standard mechanism for writers to include information in the HTML document which is only known to the Server."

Title: Process for applying low-cement castable refractory material
Inventor: ALLISON ERIC L
IPC: C04B40/00
Filed: 1995-07-07
Abstract: A method for placing a thixotropic low-cement castable refractory material without the necessity for forms. A low-cement castable material is mixed with a measured amount of water, then is pumped hydraulically through a hose (13) to a nozzle assembly (14). Compressed air and a cement setting agent are added to the mixture at the nozzle (14). The addition of the setting agent at the nozzle (14) overcomes the thixotropic nature of the low-cement castable, so that it will immediately "set" in position when sprayed onto a surface, including vertical and overhead surfaces.
