IPC: C25C3/08
Filed: 1993-06-11
Abstract: A carbon containing paste for use in particular as components of electrolytic cells as such or compacted to form anodes, cathodes and cell linings of cells for the electrolysis of alumina for the production of aluminium, consists of a compact mixture of one or more particulate carbonaceous material(s) with a non-carbonaceous non-polluting binder and optionally with one or more fillers, especially alumina and aluminium, the binder being a suspension of one or more colloids such as colloidal silica, alumina, yttria, ceria, thoria, zirconia, magnesia, lithia or being derived from one or more colloid precursors or colloid reagents optionally with one or more chelating agents. Cell components are produced by forming the paste to a desired shape and size, for instance in a mold, an injection die or in a cell bottom, compacting and drying before use, or the paste can be used as such like in a Soderberg type anode, or for bonding together carbon blocks like a ramming paste.

Patent CA-2143490-A1 (CA)
Inventor: BAKER DAVID C
IPC: H04N5/44
Filed: 1995-02-27
Abstract: Bytes of different types of digital information, including standard interframe video (SIF), graphics, television and audio are transferred between a controller, storage memory and shift registers (e.g. FIFO's) individually associated with the different information types. For a VRAM memory, information is transferred in parallel, controlled by tag bus information, from the controller to the memory and then serially to the FIFO's, all at a frequency higher than a clock frequency in a monitor raster scan. The tag bus information is decoded and introduced to an additional FIFO. A state machine processes such additional FIFO information and transfers the digital information to the different FIFO's at times controlled in each line by such additional FIFO- e.g. particular times in each line for the SIF and graphics and thereafter, for television and audio, at times unrelated to any times in such line. The graphics transfer is timed to substantially fill, but not overflow, in such line the limited capacity of the associated FIFO. Their limited capacities cause the television and audio FIFO's to stop receiving bytes when filled to particular limits. For a DRAM memory, information is transferred, dependent upon the tag bus information, in parallel between the controller, memory and FIFO's at the clock frequency. In a "Rambus" system, a bus common with the controller, memory and FIFO's provides control and timing bytes. The information in successive bytes transferred through the common bus to the controller, memory and FIFO's dependent upon such timing and control information in such bytes.

Title: Device for the equalization of data flow
Inventor: HUG WERNER
IPC: H04L12/54
Filed: 1995-06-07
Abstract: In networks with switched broad-band communication, agreements exist between customer and network operator with regard to permissible data flows, which are maintained by a usage parameter control. To attempt to utilize the capacity of the network as much as possible, the network operator offers a service of utilizing the available bit rate frequency. This service requires a separate treatment of the respective data, to maintain the priorities and avoid overloading of the switching unit. The device for equalizing the data flow contains a switchingnetwork (22) which is located upstream of the switching unit (10), and reroutes the data flow that utilizes the available bit rate frequency service, to a server (23). This server preferably comprises an addressable buffer memory which is common to all rerouted connections, so that an equalization to the switching unit (10) takes place through all physical connections (1), and the buffered data can still be read in an orderly manner, in accordance with selected criteria.

Title: Sure-step i
Inventor: BARON STEVEN RICHARD
IPC: G09F15/00
Filed: 1995-12-01
Abstract: A welded steel structure used in conjunction with corrugated plastic for an upright sign display. It consists of a square, steel, longitudinal tube into which is inserted a fork-shaped wire structure. The centre of the fork-shape is welded to a flat rectangular piece of steel which is in turn welded to the fork-shaped wire. This flat rectangular piece is what is inserted into the longitudinal tube. At the base of the longitudinal square tube, a metal bar is welded to create a step. To the bottom of the step a triangular shaped spike with a flange is welded. The fork configuration is inserted into the flutes found in the corrugated plastic and the spike is pushed into the ground by the installer's foot. This fork structure allows the sign to be posted in a stable manner, providing flexibility against force, such as strong winds. The longitudinal tube is of a strong steel and is the main support for the apparatus. The fork-shaped wire is of a thickness consistent with the cores of commercially manufactured corrugated plastic. The entire apparatus is powder coated to provide a rust-proofed structure which is aesthetically pleasing. This invention results in a two piece apparatus requiring no tools for its application and eliminates the need for hardware, i.e., nuts and bolts, used in other sign systems. Because the wire is powder coated, it is resistant to rust and may therefore be used repeatedly.
