Patent CA-2036873-A1 (CA)
Inventor: FERLAND LAURIER
IPC: A01G23/089
Filed: 1991-02-21
Abstract: Dans l'utilisation mécanisée de la coupe d'arbres en forêt, plusieurs méthodes ont été utilisées depuis nombre d'années. L'invention ci-jointe va permettre de révolutionner l'abattage d'arbres en foret tout en préservant tout dommage à la repousse. L'utilisation des têtes de bucheuse plus légères et plus petites va maintenant être possible grâce à cette invention de lames de scie mobiles. En étant plus petites, les nouvelles cisailles vont pouvoir être fabriquées de matériaux plus légers et vont aussi permettre l'utilisation de machinerie plus petite et moins côuteuse. La tête à scie ronde utilisée depuis quelques années nous a prouvé que sa manipulation endommage l'environnement (la repousse) et justifie grandement l'implantation d'une nouvelle invention. Par ce nouveau genre de scie (modèle à lame avec dents interchangables) la coupe en forêt va ressembler aux coupes des années antérieures avec un mécanisme d'avant-garde. Les coupes à blanc connues aujourd'hui sont en voie de disparition. On favorise de plus en plus la coupe SELECTIVE et pour accéder à cette demande, la SOLUTION est la cisaille à lames de scie mobiles avec dents, le tout installé sur de la machinerie plus VERSATILE.

Title: Electromechanical bidirectional rotation device
Inventor: SHAH REZA H
IPC: F16K31/04
Filed: 1991-04-05
Abstract: ABSTRACT OF THE DISCLOSURE    The bidirectional rotation device comprises a direct current motor connected in series with a capacitor and a reversible switching means. When a direct current voltage is applied to the series-connected combination of direct current motor and capacitor through the switching means in one posi-tion, the charged capacitor causes the motor to rotate in one direction for a short period of time; and when the voltage is again applied to the combination in the reversed polarities, the reversely charged capacitor will cause the motor to rotate in the reverse direction.

Title: Self-diagnosis and repair system for image forming apparatus
Inventor: TOMIYAMA TETSUO
IPC: G03G15/16
Filed: 1991-09-20
Abstract: ABSTRACT OF THE DISCLOSURE         This system according to the invention has plurality of sensors 1a, 1b and 1c, a system control circuit 10 and plurality of actuators 6a, 6b and 6c.  In response to an application of state data from the sensors 1a, 1b or 1c, the state data is compared with characteristic data in the system control circuit 10.          Consequently, it is judged that a fault is caused depending on whether the state data is relatively lower or higher.         If a fault is caused, inference of the fault caused is drawn on the basis of a comparison between qualitative data and fault diagnosis knowledge which are stored in the system control circuit 10.  Then, it is judged which of elements of a image forming apparatus is abnormal.  Accordingly, actuator operating signal is outputted as the results of the judgement.
Patent CA-2055031-A1 (CA)
Inventor: MOCHIZUKI DAVID A
IPC: E21B7/00
Filed: 1991-11-06
Abstract: A portable drilling apparatus designed to be used in environmentally severe locations, such as the Arctic, includes provisions for heating various portions thereof, including a pipe shelter.  The pipe shelter is used to store, warm, and clean the drill pipe and/or casing prior to insertion in the well.  Thus, to provide access for loading the drill pipe and/or casing into the pipe shelter, a significantly large opening must be provided.  The large opening necessarily results in significant infiltration of arctic air and loss of heated air, thereby increasing the difficulty of maintaining the pipe shelter at a comfortable working temperature.          Accordingly, a high-speed spool or window-shade style door is employed to seal the opening against large scale transfers of heated and cold air.  Further, an indirect fired air-heater having a capacity sufficient to maintain a positive pressure in the pipe shelter is also used.  The positive pressure within the pipe shelter causes warm air to exit rapidly when the door is opened, and thereby reduces the inflow of arctic air.  Accordingly, the combination of the high-speed door and positive pressure environment within the pipe shelter combine to provide a relatively stable and comfortable temperature environment.

Abstract: ABSTRACT      The present invention relates to a process for the production of kryton and xenon by using an oxygen-free vapor stream to strip a liquid stream containing oxygen, krypton, methane, and xenon of methane and oxygen.  This is accomplished by properly controlling the liquid to vapor flow ratio in the distillation column so that such ratio is less than 0.15.  A suitable reflux liquid is used to decrease the loss of krypton and xenon in the methane and oxygen laden vapor stream leaving the distillation system.

Title: Determining and marking apparatus and method for use in optometry and ophthalmology
Inventor: MARSHALL FORREST A
IPC: G02C13/00
Filed: 1991-01-18
Abstract: An apparatus and method for subjectively determining the proper positioning of progressive power or other corrective lenses are disclosed. The apparatus includes a target such as a small fiber optic or other light source and one or more marking rods which may be activated by the patient. While wearing pre-fitted frames and fixating on a remote target, the patient places the light source against or immediately adjacent the exterior surface of the simulated or other lens within either of the frames and positions the light so that it is centered in his or her line of sight. Once the light is centered the patient activates the marking rod which contacts, and marks, the exterior surface of the lens. Because the light source and marking rod or rods are designed to obstruct very little of the patient's vision, his or her peripheral vision remains intact during the process, thereby allowing binocular fusion to occur and avoiding introduction of phoria errors into the positioning process.
Patent CA-2073966-A1 (CA)
Inventor: QUIGG FRED L
IPC: H01L29/78
Filed: 1991-01-22
Abstract: In one embodiment, a vertical MOSFET is formed having a lower gate portion (124) overlying the channel region of the MOSFET and separated from the channel region by a thin gate oxide layer (90).  An upper gate portion (120) is formed overlying the drain of the MOSFET and separated from the drain by a relatively thick oxide layer (86). In this particular embodiment, since the dielectric thickness between the upper gate portion (120) and the drain (82) is relatively large, the MOSFET exhibits a lower gate-drain capacitance (CGD) value, while the threshold voltage of the MOSFET  remains relatively unchanged. The upper gate portion (120) may be electrically connected to the lower gate portion (124) or may be electrically isolated from the lower gate portion (124). A preferred method of forming the resulting MOSFET having this lowered CGD allows the source (92) and body regions (88) to be precisely aligned with the drain edge of the lower gate portion (124).
