Title: Implement attachment means for mechanical diggers
Inventor: NORGREN RUNE
IPC: E02F3/36
Filed: 1991-09-27
Abstract: Abstract An implement attachment means for fitting to a digging machine, particularly a deep digging machine includes, in a known manner, a working yoke (2) which is pivot-ally mounted on the implement-carrying arm (1) of the machine and which can be rotated in a plane lying in the implement-carrying arm (1) by means of a working piston-cylinder device (3).  The implement attachment means includes a first link (4) and a second link (5) which is spaced from the first link.  The first link has the form of a pivot which is moveable at least in two substantially perpendicular directions (7 and 8) and is connected to the implement-carrying arm (1), and the second link has the form of a working arm (12) and a reciprocatingly moveable force generator (13).  The working arm (12) and the force generator (13) lie in a plane which is substantially perpendicular to the rotational plane of the working yoke (2) and are pivot-ally connected to the working yoke (2).            (Figure 1).

Title: Overlapped serialization
Inventor: COMFORT STEVEN T
IPC: G06F9/38
Filed: 1991-11-29
Abstract: OVERLAPPED SERIALIZATION               ABSTRACT       A system and method whereby a central processor can continue operation beyond a serialization point before the architecture  defines that  it  is  permissible  to  do  so. According  to  the  system  and  method,  it  is  ascertained whether  correct  results  are  being  achieved  after  the serializing  point.   If  some  doubt  develops  about  the correctness of the results, the processor is returned to its status  at the  serialization point  and  the processing is repeated.   In  one  embodiment,  correctness  of  results  is determined by way of a monitoring mechanism which depends on the fact that the interactions between CPUs are confined to references to storage.  The operations which are performed prior to the time that the architecture allows  them, are restricted  to  ones  which  depend  on  fetches  made  from storage.   The  needed  assurance  of  correct  operation  is gained  by  monitoring  the  storage  locations  from  which fetches are made on behalf of instructions which logically follow the serializing operation, but which are made prior to the time that fetching is allowed to resume.   If those storage locations are not changed during the time between when the first such fetch is actually made from one of them, and the time that fetching is allowed to resume, then the results of the processing which was done by the CPU (based on those fetches) must be exactly the same as if all of the fetches  and all  of the processing was done  in a  single instant at the moment that the fetches became allowed.
Patent CA-2057379-A1 (CA)
Title: Stage scale
Inventor: ARNOLD MILTON E
IPC: G01B3/04
Filed: 1991-12-11
Abstract: Abstract A scale rule for use specifically, but not exclusively, with stage plans, lighting plots, and other such drawings or diagrams where dimensions are referenced from a central zero point and increase to both the right and left of this point. Measurement by this method insures that, regardless of the peripheral dimensions of the performance space, once the center line of the stage has been located measurements from the plan can be easily and consistently transferred. For example, a certain scenic element is three meters toward stage left from the center line or a certain lighting fixture is five meters toward stage right from the center line. To facilitate this type of measurement this scale has the zero point in the center of the rule and increasing increments along the scale to both the right and left of this point.

Title: Reactive distillation process and apparatus for the implementation thereof
Inventor: ASSELINEAU LIONEL
IPC: B01D3/00
Filed: 1992-12-16
Abstract: A reactive distillation process is described, making it possible, in the same vessel, to carry out a catalytic reaction and to isolate the required product by distillation, in which the liquid phase containing the reactants passes from the top downwards through at least one catalyst bed without the vapour phase of the distillation passing through the said catalyst beds. These operating characteristics are in practice obtained in a reactive distillation zone (C) which comprises an alternation of distillation cells (D) comprising one or a number of trays (5) and of reaction cells (R) containing the catalyst beds and designed so that the liquid phase flowing off a distillation tray (5) flows over a spillway (7) via a down column (6) to reach the catalyst bed (8) at its bottom and to pass through it as an upward stream before pouring by overspill onto a distillation tray (5) of the following distillation cell (D), so that the distillation vapour which travels from the bottom upwards through the distillation trays (5) does not pass through the said reaction cells (R). Each reaction cell (R) is physically separated from the adjacent distillation cell(s) (D). The process and the apparatus which are described can be applied particularly to the reactions of synthesis of tertiary alkyl ethers by addition of aliphatic monoalcohols (methanol, ethanol) to isoolefins (isobutene, isopentene). <IMAGE>

Abstract: The hierarchical distributed knowledge based system functions in a machine initiated maintenance environment to provide efficient and timely maintenance of customer equipment (40-42). The hierarchical, distributed knowledge based system provides the failure evaluation function through the use of an expert or knowledge based system (11) that is installed in the customer equipment (40).  This knowledge based system (11) identifies the occurrence of a failure within the customer equipment (40) and functions using its rules, hypotheses and collected data to isolate the source of the error in the customer equipment (40) and, whenever possible, ''fence'' or isolate the failed field replaceable unit that has caused the error. A significant additional attribute of this system is the provision of at least one more level (1, 30) of knowledged based system to provide a more global failure evaluation capability.
