Patent CA-2205236-A1 (CA)
Inventor: FUKANO YUJI
IPC: F02N11/08
Filed: 1995-11-16
Abstract: L'invention concerne un dispositif destiné à améliorer la sécurité et la fiabilité d'un dispositif de démarrage et d'arrêt de moteur à distance pour engins de construction. Un signal de démarrage destiné à démarrer un moteur est envoyé à un engin de construction par un moyen de transmission séparé dudit engin. Le signal de démarrage est reçu par un moyen de réception prévu sur l'engin de construction. Lorsque le signal de démarrage est reçu par le moyen de réception, un dispositif de démarrage de moteur est activé pour démarrer un moteur, à condition qu'un levier de manoeuvre pour engin de terrassement au point mort soit détecté par le moyen de détection de point mort. Ainsi, le risque que l'engin de construction se mette en marche sans surveillance humaine est supprimé et la sécurité améliorée. De plus, si le moteur ayant fonctionné est détecté par le moyen de détection de fonctionnement après qu'un dispositif de démarrage de moteur ait été activé par le moyen de démarrage de moteur, le moteur tourne pendant un certain laps de temps après la détection. Ainsi, le préchauffage du moteur s'effectue pendant une période prédéterminée à partir d'un certain moment où le moteur fonctionne réellement, ce qui permet d'améliorer la fiabilité en cas de fonctionnement sans surveillance.

Title: Unstructured supplementary service data from a home location register to an external node
Inventor: ASTR M BO
IPC: H04M3/42
Filed: 1995-12-15
Abstract: A system and method is provided for controlling the signalling between the subscriber of a mobile station and an external service node such as a message center. The control of the signalling is carried out by using unstructured supplementary service data (USSD) which is analyzed by a USSD handler of a home location register which invokes a transparent transfer to external service node (TTEN) application when the USSD does not correspond to a service defined within the home location register. The TTEN application establishes a dialog with the subscriber of the mobile station and the desired external service node by using USSD. This allows the subscriber of the mobile station to access all message services by sending one service code.      Also, the operator is not busy while accessing the services and any incoming calls may be answered while accessing the services.

IPC: H01L21/683
Filed: 1997-11-26
Abstract: A holder (102) made from an HF-resistant material includes annular suction pads (105, 108).  The suction pad (105) is used to hold a small silicon substrate by suction, and the suction pad (108) is used to hold a large silicon substrate by suction.  This makes silicon substrates with various sizes processable.  A silicon substrate is held by suction by reducing a pressure in a space in a groove of the suction pad by a pump (120).  An opening (103) is formed in the holder (102) so that the both surfaces of the silicon substrate are brought into contact with an HF solution (115).  The silicon substrate is anodized by applying a DC voltage by using a platinum electrode (109a) as a negative electrode and a platinum electrode (109b) as a positive electrode, and thereby a substrate having a porous layer is produced.

Title: Conductive metal porous sheet production
Inventor: GRIESSER JOHN R
IPC: H01M4/66
Filed: 1996-07-11
Abstract: A porous product, typically a metal foam sheet, is produced as a tailored, engineered product. The porous product can have enhancec strength, as well as more desirable electrical and mechanical properties. The product which first exists typically as a flexible, generally polymeric foam sheet in strip (12) form, which strip (12) is produced in the longitudinal direction, is stretched in a direction other than its direction of production. The porous product can have pores which would be anisotropic in form in usual production, which are stretched to at least substantially isotropic form. The product can even be tailored to have pores which are anisotropic in the direction of the stretch. Thus, an engineered product can be produced which, for example, as an opencell metal foam prepared from a polymeric foam, can have conductivity, both thermal and electrical, as well as strength and ductibility, tailored for greater uniformity and performance.

Title: Radial-flow distributor for wide uniform nonturbulent non-dribbling pouring of molten metal into a continuous metal-casting machine--methods and apparatus
Inventor: KAGAN VALERY G
IPC: B22D11/06
Filed: 1998-05-27
Abstract: A radial-flow, wide-pouring molten-metal distributor comprising a curved or arcuate overflow weir which is normally horizontal on its top and which is concave on its upstream side as viewed from above. Over this arc-shaped overflow weir flows molten metal to be continuously cast in an open pool. An impetus is thereby imparted to the molten metal along diverging radial lines. The flow so impelled continues radially onto a horizontal apron. The flow spreads fanwise to the desired width which may be as much as six times the width of the weir. Thence, the metal cascades or flows uniformly into the casting apparatus. The overflow weir is preferably supplemented by a skimmer mounted above it in substantially uniform spaced aligned relationship, thereby completing a slot beneath the skimmer through which the molten metal flows. When employed for the casting of wide, thin product, the invention results in a far more uniform and gentle distribution of metal than heretofore available. Dribbling and "beards" are eliminated. Swirls and porosity are reduced. The temperature profile across the section being cast is rendered more uniform, thereby permitting a lower temperature of the supply of molten metal entering this novel distributor.

IPC: B66F9/20
Filed: 1998-07-20
Abstract: A control  system for  an electric  lift  truck that controls a traction motor and a hydraulic pump motor is disclosed.   The speed of rotation of both motors is controlled by a pulse width modulated current supplied from  a  battery  source  by  the  controller  in  direct response  to  a  demand  communicated  to  the  controller through an interface manipulated by an operator.  A pump driven by the pump motor supplies pressurized hydraulic fluid to a lift mechanism and a power assisted steering unit.  A joystick with function switches mounted thereto is provided so that the operator steers with one hand while controlling truck propulsion and all functions of the  lift mechanism with  the other  hand.    The  direct control  of  the  pump  motor  speed  enables  a  fully proportional  control  of  the  hydraulic  system.    The control  system  is  a  compact  structure  that  requires minimal  cabling and ensures  that  the hydraulic  system operates with energy efficiency and minimal wear.

Title: Method for increasing yield of liquid products in a delayed coking process
Inventor: ROTH JIM R
IPC: C10B57/12
Filed: 1997-02-07
Abstract: In a delayed coking process the temperature of the liquid in the coke drum (4) is increased by the addition of a heated non-coking hydrocarbon diluent. The heated non-coking diluent can be added to either a delayed coker furnace effluent prior to entering the coke drum (4), directly into the coke drum (4), or both. The resulting increase in coke drum temperature results in increased liquid yields and decrease in coke yields.
