Patent CA-2081476-A1 (CA)
Title: Symbol table for intermediate compiler language
Inventor: FAIMAN ROBERT N JR
IPC: G06F9/45
Filed: 1992-02-18
Abstract: A compiler framework uses a generic "shell" or control and sequencing mechanism, and a generic back end (where the code generator is target-specific). The generic back end includes the functions of optimization, register and memory allocation, and code generation. The shell may be executed on various host computers, and the code generation function of the back end may be targeted for any of a number of computer architectures. A front end is tailored for each different source language, such as Cobol, Fortran, Pascal, C, C++, Ada, etc. The front end scans and parses the source code modules, and generates from them an intermediate language ("IL") representation of the programs expressed in the source code.  This IL is constructed to represent any of the source code languages in a universal manner, so the interface between the front end and back end is of a standard format, and need not be rewritten for each language-specific front end. The IL representation generated by the front end is based upon a tuple as the elemental unit, where each tuple represents a single operation to be performed, such as a load, a store, an add, a label, a branch, etc. A data structure is created by the front end for each tuple, with fields for various necessary information. One feature of the invention is a mechanism for representating effects and dependencies in the interface between front end and back end; a tuple has an effect if it writes to memory, and has a dependency if it reads from a location which some other node may write to. A mechanism independent of source language is provided for describing the effects of program execution. Another feature is the use in the optimization part of the compiler of a method for analyzing induction variables, where the improvement is to use the side effects sets used to construct IDEF sets. Another feature is a mechanism for "folding constants" (referred to as K-folding or a KFOLD routine), included as one of the optimizations. A further feature is the type definition mechanism, referred to as the TD module, which provides mechanisms used by the front end and the compiler of the back end in constructing program type information to be incorporated in an object module for use by a linker or debugger. Another feature is a method for doing code generation using code templates in a multipass manner.
Patent CA-2082118-A1 (CA)
Inventor: LIEN YEONG-CHANG
IPC: G06F13/36
Filed: 1992-11-04
Abstract: A computer system is provided which allows adapters to  be  inserted  or  removed  while  keeping  the  system operational, and which can automatically reconfigure the system according to such insertion or removal. When  an  adapter  is  inserted,  an  adapter  detection mechanism informs a resource manager of the insertion of the adapter with an interrupt or the like. The resource manager electrically and mechanically connects the adapter immediately after its insertion, and reads the attribute information of the adapter  from a memory on the adapter  to perform  the necessary setup, inclusion of the device driver necessary for the system, and assignment of memory and the like, thus enabling the adapter.  When a user wants to remove an adapter, he or she issues an adapter removal request from an adapter removal  button,  or  from  a  program  to  the  resource manager.   This  request is transmitted to the resource manager, which checks the running state of the adapter, and,  if  it  can  be  removed,  electrically  and  then mechanically disconnects it so that it can be removed. The user of the computer system removes the adapter after it is disconnected.

Title: Rotating plug
Inventor: MCQUOID SEAN W
IPC: H01R39/08
Filed: 1993-09-13
Abstract: Abstract This device is a rotating plug. Since all sockets seem to be oriented the same way, i.e. the ground plugs on a set of sockets are always on the top or on the bottom of the socket, the rotating plug allows for plugs to be oriented in such a manner that the wires of the plugs in a set of sockets do not interfere with each other.      The condition described above is prevalent in nearly all existing sockets. The rotating plug allows for ease of use with the new "L" shaped plugs of both grounded and non-grounded types. Existing "l" shaped plugs will not be affected. The plug is rotated by simply pushing down on the upper section and rotating the lower section clockwise or counterclockwise to the desired configuration. When the pressure is released, the plug is then set so that the cord is in the new and satisfactory position.

Title: Forming belt for three-dimensional forming applications
Inventor: PARTRIDGE MARY E
IPC: D21F9/00
Filed: 1994-03-25
Abstract: ABSTRACT            A method and apparatus for forming a layer structure, such as an airlaid fibrous web, include a supplying mechanism for providing a stream of particulate material, such as fibers.  Also included is a substantially endless, foraminous forming belt which has an appointed outward surface and a minimum thickness of at least about 3/16 inch. A selected contour is formed into the outward surface of the belt at selected locations, and the contour is distributed along a lengthwise machine-direction of the forming belt.  The forming belt is configured to flex along a thickness direction thereof, and to recoverably bend and substantially straighten when traveling along a selected belt path circuit.  A conveying mechanism moves the forming belt past the supplying mechanism along a forming path section of the belt circuit which is substantially straight, and moves the forming belt along a return path section of the belt circuit which includes curved portions therein.  A vacuum mechanism draws a flow of air through the thickness of the forming belt to lay the particulate material onto the forming belt to form a layer structure, such as a web, having a top surface and a belt-side surface thereon.  The web is thereby produced with a selected non-uniform thickness contour which is formed along the belt-side surface of the fibrous web.  A driving mechanism moves the forming belt along the machine-direction at a selected speed, and a transporting mechanism removes the contoured web from the forming belt.
