Title: Method of producing a slideway-type guide
Inventor: STEHLE HANS P
IPC: B27B17/02
Filed: 1994-01-14
Abstract: A B S T R A C T      This method serves for the production of a slideway-type guide for driven chains, eg cutting-chains. A running surface made of wear-resistant hard alloy is applied to the slideway of the guide. A blank in bar form with a dentritic structure, made from said alloy, is produced to form the running surface, a suction casting process being used in particular for this purpose. The blank is treated with high pressure at a high temperature. This method is known as hot isostatic pressing. This is followed by an annealing process over a number of hours, at the end of which the structure of the alloy is so altered that the previously acicular and to-some-extent skeletally-joined carbides are dispersed and converted to rounded, to some extent spheroidal bodies which are densely and evenly distributed throughout the alloy. The alloy thereby becomes highly wear-resistant. The bars are then shaped so as to fit onto the slideway, and are bonded rigidly thereto.

Patent CA-2117846-A1 (CA)
Inventor: REITER ALLEN
IPC: G06F12/00
Filed: 1994-10-11
Abstract: A computer method and storage structure for storing and accessing multidimensional data is provided. A tree manager provided by the present invention stores data such as pointers, variable length data records, other B-trees, and directories, in a Multidimensional B-tree (MDB-tree). An MDB-tree has an imbedded "parent-child" structure which allows subtrees to be stored within nodes. The subtrees contain subnodes, which, in turn, may contain subtrees. The nodes are indexed by a primary key value while the subnodes in a subtree are indexed by secondary key values. Nodes of a MDB-tree contain a key value table, a subnode table, and a data area. When the tree manager attempts to store a unit of data on a page and the unit of data is too large for the page, the tree manager attempts to split a node currently stored on the page (or the unit of data being inserted) into a subnode and a subtree. The subtree is then stored on a new page. If the unit of data cannot be split into a subnode and a subtree, then one or more of the node currently stored on the page are moved to a new page.

Patent CA-2136499-A1 (CA)
Title: Conditioning roller assembly
Inventor: TALBOT FRANCOIS
IPC: A01D82/00
Filed: 1994-11-23
Abstract: A chain drive system is provided for communicating rotation from the bottom roller of a hay conditioner to the top roller of the hay conditioner. The top and bottom rollers include longitudinally extending flutes which intermesh as the rollers rotate. The top roller is mounted for movement at each end upwardly away from the bottom roller to accommodate increased quantities of crop or obstacles. The chain drive maintains angular synchronism between the rollers despite movement of the top roller away from the bottom roller. This is achieved using a single chain wrapped around a drive sprocket on the bottom roller and around two idlers arranged at the apexes of a triangle. The driven sprocket on the top roller is located within the triangle so that the chain wraps around the drive roller into the triangle, around the driven roller and back to the idler at the apex. The top roller is mounted for pivotal movement about an axis midway between the idler sprocket and the drive sprocket and located just outside a line joining the axes of those sprockets. This location of the pivot point and the proper selection of the length of the pivot arm maintains the chain path constant despite the movement of the roller and maintains the required angular synchronism.

IPC: B09B3/00
Filed: 1993-03-10
Abstract: Baffles can form a chimney-effect separating the vapor space near the center of the bath. Flow through the chimney is aided by thermal convection and, optionally, by a differential pressure between the portions of the bath on either side of the baf-fle-chimney arrangement.  Feed is added to the feed zone and oxygen is added to the oxidation zone, emitting H2 from the feed zone and CO from the oxidation zone. Products can be mixed as syngas feed for Fischer-Tropsch synthesis. Additionally, the Boudouard endothermic reaction (CO2 + C -> 2CO) can be used to control temperatures by injecting CO2 in place of oxygen. A plural zone plant and process for converting a hydrocarbon feed (e.g. coal, automobile tires, hazardous organic wastes, such as polyhalogenated organics, organic polymers, garbage, and other hydrocarbons) to synthesis gas comprising carbon monoxide and hydrogen is disclosed.  The feed is contacted with a molten bath, which can comprise iron in an oxy-gen deficient zone at one pressure and reacted with water, and/or an oxygen source, in at least one other zone having higher temperature and pressure than the first zone.

Title: Computer Failure Recovery and Alert System
Inventor: BURCKHARTT DAVID M
IPC: G06F11/00
Filed: 1993-09-24
Abstract: A computer system includes a timer which times out if the operating system does not periodically reset the timer.  When the system fails and no longer resets the timer, the timer times out, and the computer is reset. The system performs its power on program and checks the memory array for bad memory blocks, which are mapped out of the memory.  Next, the system alerts the operator of the failure using a pager.  The system then reboots itself from a hard drive having two separate bootable partitions, one for the operating system in the first partition, and one for a diagnostics program in the second partition, so that an operator may diagnose and remedy the problem.  The operator may set an indication of which partition to use for booting. The system further provides for remote access so that the operator may interact with the diagnostics program from a remote location.
