Patent CA-2363998-A1 (CA)
Inventor: SCHMUCKER ERWIN
IPC: B28B7/30
Filed: 2001-11-28
Abstract: The side walls of a mold have recesses in each of which is mounted a mold core for forming depressions on the outer side of a concrete block which is to be produced in this mold. The mold cores are pivotally supported around a horizontal axis which is parallel to the mold walls on the outer side of the mold. A sloping cam slot on each mold core is used to pivot the mold cores into the mold cavity defined by the mold walls and then back into the recess. The inner edges of a recess closely fit the mold core and function as strippers which self-clean all surfaces of the mold core which have come into contact with the concrete when the mold core is pivoted back into its recess. As a result, time intervals far cleaning the mold cores are greatly lengthened and a clean and smooth surface of the finished concrete black is insured.

Patent CA-2364931-A1 (CA)
Title: Bolted joint for rotor disks and method of reducing thermal gradients therein
Inventor: PEPI JASON FRANCIS
IPC: F16B5/02
Filed: 2001-12-13
Abstract: Bolt hole stress in rotor disks having bolted joints is reduced by passing relatively hot secondary flow path air (such as compressor discharge air) through each bolt hole (70) to heat the disk (40) from inside the bolt hole (70). In doing so, the temperature distribution in the area of the bolt hole (70) is made more uniform and the stress is dramatically reduced. The bolted joint (52) includes a bolt hole (70) formed in a first rotor disk (40) and a bolt (66) disposed in the bolt hole (70) such that a channel (84) is defined between the bolt (66) and the bolt hole (70). A first nut (74) or abutment is attached to a first end of the bolt (66), and a second nut (76) or abutment is attached to a second end of the bolt (66). A first passage (86) associated with the first abutment (74) provides fluid communication with the channel (84), and a second passage (88) associated with the second abutment (76) provides fluid communication with the channel (84), thereby allowing the relatively hot fluid to pass through the channel (84) during engine operation.

Abstract: An operating mechanism for an autorecloser provides an improved form of mechanical interlock between the circuit breaker element (3) of an autorecloser and a disconnector (2) in electrical series with it. A shaft (8 2) transmits linear motion between the circuit breaker's moveable contact and t he profile of a bell crank (50), the bell crank being attached to a link (70) f or manual rotation of the bell crank and also to a link (60) for moving a moveable contact (20) of the disconnector between CLOSED and OPEN positions.  The geometry of the bell crank profile and linkages is such that when the be ll crank is rotated clockwise through an angle X from a starting position in which the moveable contacts of both the circuit breaker and the disconnector  are in the CLOSED position, the moveable contact of the circuit breaker is moved to an OPEN position while the moveable contact (20) of the disconnecto r is maintained CLOSED. During further clockwise rotation of the bell crank (5 0) through a further set angle Z to a predetermined limit of movement of the be ll crank, the moveable contact (20) of the disconnector is moved to an OPEN position while the moveable contact of the circuit breaker is maintained in the OPEN position by a sector of the bell crank profile (59) which is of constant radius R2. When the bell crank (50) is rotated back to its starting  position, the moveable contact (20) of the disconnector is moved back to its  CLOSED position before the moveable contact of the circuit breaker is moved back to its CLOSED position.

Abstract: A method for synchronizing nodes in a network is described that utilizes an interactive convergence technique. The technique utilizes communications protocol IEEE 1394 to broadcast each node's clock value to the other nodes i n the network in step 301. Each node applies a voting algorithm to the set of broadcasted clock values to determine a voted clock value in step 303 and ea ch node's clock is set to that voted clock value in step 305. When a node's clo ck value is close in value to another node, those nodes are considered to be synchronized in step 302. The set of clock values to be used to determine th e voted clock value consists of those nodes that are synchronized. The techniq ue is implemented on hardware separate from the node's hardware and can be implemented on a field programmable gate array.

Abstract: L'invention concerne un système de réflecteurs et une base de luminaire fluorescente parabolique permettant de concentrer et de guider la lumière. Ce système est conçu de manière à améliorer sa production de lumière et la réduction parallèle des coûts de construction. Sur la base de support (1) des composants électriques du luminaire, deux des quatre parois latérales sont composées d'accessoires de plastique séparés (6) assemblés grâce à un enclenchement facile et rapide sur le corps principal (5) de la base en feuille ferreuse (1). Les parois latérales de plastique (6) de la base (1) possèdent des cavités spécifiques et des projections (11, 12) afin de maintenir une grille de réflecteurs paraboliques (2, 3) séparable et qui comporte deux parties séparées. Une partie est constituée par les composants paraboliques principaux (2) de direction de la lumière, qui sont placés sous les lampes fluorescentes (4) alors que l'autre partie est la grille supérieure en croix (3), que l'on peut retirer du luminaire sans toucher aux composants paraboliques principaux (2). Ainsi, ces derniers (2) n'ont pas besoin de présenter des ouvertures le long des lampes (4). En conséquence, leur forme parabolique continue améliore grandement la production de lumière du luminaire parabolique.

Abstract: A method for maintaining IPCP address negotiations in a wireless communication network is presented. The method includes a communication device receiving a message requesting an IP address, such as a Config-Request message, from a terminal device, which is coupled to the communication device. The communication device then generates a message requesting an IP address, such as a Config-Request message, and forwards it to a peer (IWF) within the network. The communication device then determines whether it has received an assigned IP address from the IWF in response to the IP address request message. In response to determining that the communication device has not received the assigned IP address from the IWF, the communication device transmits a message with an arbitrary IP address, such as a Configure-Nak message, to the terminal device. The arbitrary IP address contained within the message will be rejected by the communication device, upon receipt of future Configure-Requests containing the arbitrary address. This triggers the terminal device to keep transmitting additional IP address request messages until the communication device has received the assigned IP address.
