Title: Multi-purpose public facsimile transmission terminal
Inventor: MASSEY JOHN C
IPC: H04N1/00
Filed: 1991-10-18
Abstract: MULTI-PURPOSE PUBLIC FACSIMILE TRANSMISSION TERMINAL                 Abstract of the Disclosure A multi-purpose public facsimile transmission terminal otherwise known as a public fax terminal, employs a stand alone kiosk with  a  touch  activated  computer  display  color monitor presentation, advising the user of the operational steps to take in the use of the machine.  The user initiates operation by inserting a credit card in a card reader and following the instructions presented on the monitor.  A scanner mounted in the kiosk reads a document to be faxed and stores the image in the memory of a computer.  Faxed transmissions are received and sent over telephone lines by a fax modem in the computer.  Copies of faxed documents are provided by a plain paper laser printer, which also has the capability of providing copies of any scanned documents or any documents in the computer memory.   The computer memory presents video advertisements and has stored business and message forms which  can  be  retrieved  and used  as  desired.    An  interface connection open to the exterior of the terminal connects to a computer such as a laptop computer,  provided by the user to download and fax information in the memory of the laptop computer. The terminal may also be used to retrieve documents from a remote data base system.

Title: Bi-fold screen door
Inventor: WALLACE KEN
IPC: E06B3/48
Filed: 1991-10-31
Abstract: ABSTRACT OF THE DISCLOSURE           In order to achieve these and other objects of the invention, the present invention provides an improved bi-fold screen door which includes a pair of elongated panels having central rectangular mesh screen portions.  The door panels are connected by a vertically extending central piano-type hinge.  A longitudinal edge of one of the panels is secured by a hinge in a vertically extending notch formed in a door jam.  A free longitudinal edge of the opposite door panel is received in a juxtaposed notch in the door jam, when the door is in a closed position.  The door is intended for use in conjunction with a solid door having opposite vertical edges receivable in a second pair of juxtaposed notches formed in the door jam.  The bi-fold screen door includes a pair of laterally spaced, vertically aligned door handles on an interior surf ace of one of the door panels, and a single door handle formed on an exterior surface of the door panel.  In use, the bi-fold screen door is mounted on the inside of a door jam and opens inward, folding back against an adjacent wall, occupying substantially less space in an open position than a conventional full width screen door.

Patent CA-2061287-A1 (CA)
Inventor: TSUCHIYA HIROMITSU
IPC: F02P9/00
Filed: 1992-02-17
Abstract: Only one pre-gap is arranged between the ignition coil and the distributor so that it is connected in series with each of the ignition plugs in the engine.  A relay device is connected in parallel with the pre-gap.          The relay device is normally closed to supply a high voltage from the ignition coil to the distributor, bypassing the pre-gap.  Only when sensor signals indicate that the air-fuel combustion state is bad, the relay device is opened to cause the high voltage from the ignition coil to be applied to the pre-gap before being supplied to the distributor.  This construction permits the single pre-gap to serve all the cylinders in the engine and prolongs the working life of the pre-gap.

Patent CA-2081475-A1 (CA)
Inventor: FAIMAN ROBERT N JR
IPC: G06F9/45
Filed: 1992-02-18
Abstract: Une structure de compilateur utilise un système expert générique ou un mécanisme générique de commande et de séquencement, ainsi qu'un dorsal générique (le générateur de code étant spécialisé). Le dorsal générique comprend les fonctions suivantes : optimisation, affectation de registre et de mémoire, et génération de code. Le système expert générique peut tourner sur divers ordinateurs hôtes et la fonction de génération de code du dorsal peut être adaptée à diverses architectures d'ordinateur. Un frontal est adapté pour chaque source de langage différente, p. ex. Cobol, Fortran, Pascal, C, C+ +, Ada. Le frontal balaye et analyse les modules de code source et en tire une représentation en langage intermédiaire (LI) des programmes exprimés dans le code source. Ce LI est construit de façon à représenter sous une forme universelle n'importe quel des langages source, de sorte que l'interface entre le frontal et le dorsal soit en format standard et n'ait pas à être ré-écrite pour chaque frontal utilisant un langage particulier. La représentation en LI générée par le frontal a pour unité élémentaire le tuple, chaque tuple représentant une opération simple à exécuter, p. ex. charge, mémorisation, addition, étiquetage, branchement. Le frontal crée une structure de données pour chaque tuple, avec des champs pour les diverses informations nécessaires. L'invention comporte un mécanisme pour représenter des effets et des dépendances dans l'interface frontal-dorsal; un tuple a un effet s'il écrit en mémoire, et il a une dépendance s'il lit à un emplacement où un autre noeud peut écrire. Un mécanisme de langage source permet de décrire les effets de l'exécution de programmes. En outre, la partie optimisation du compilateur utilise une méthode d'analyse de variables d'induction, dont l'amélioration consiste à exploiter les ensembles d'effets secondaires utilisés pour construire des ensembles IDEF. L'invention comporte également un mécanisme de « réduction à des constantes » (appelé réduction-K ou routine KFOLD), compris dans une des optimisations. Elle comprend aussi un mécanisme de définition de type, appelé module TD, qui fournit les mécanismes utilisés par le frontal et compilateur du dorsal afin de construire de l'information de type programme à incorporer dans un module objet pour l'usage d'un relieur ou d'un débogueur. L'invention comprend aussi une méthode de génération de code au moyen de modèles de code en plusieurs passages.
