Patent CA-2174636-A1 (CA)
Title: Temperature-controlled laser sintering
Inventor: BENDA JOHN A
IPC: B29C67/00
Filed: 1994-10-20
Abstract: A temperature-controlled laser sintering sys-tem includes a laser beam (12) which is focussed onto a sintering bed (38) by a focussing mirror (26) and a set of scanning mirrors (32, 34). Thermal radiation (114) emitted from the sintering bed (38) are imaged to the scanning mirrors and to a dichroic beamsplitter (110) which reflects such radiation but passes the wavelength of the laser beam (12). The radiation (118) is focussed onto an optical detector (126) which provides a signal on a line (128) to a power control circuit (104). The power control cir-cuit (104) controls a modulator (100) which mod-ulates the power of the laser beam (112) so as to maintain the thermal radiation omission (114) (and thus the temperature at the sintering location) at a substantially constant level.

Abstract: Appareil et procédé de détection d'une collision oblique, d'une collision centrale avec un obstacle tel qu'un poteau ou analogue, ou d'une collision frontale sur toute la partie avant du véhicule, au moyen de signaux d'accélération correspondant aux sens longitudinal, transversal et vertical du véhicule. Le signal d'accélération détecté par un capteur d'accélération est filtré (S2) puis transféré à une unité (S6) de détection de collisions. Cette unité (S6) de détection de collisions détecte une collision dangereuse et produit un signal de réinitialisation. Le signal d'accélération détecté par le capteur d'accélération subit une intégration (S5). La détection de l'un des trois types de collision se fait par comparaison du signal d'accélération intégré avec chaque valeur prédéterminée. Une collision frontale à basse vitesse sur toute la partie avant du véhicule et une collision centrale à haute vitesse avec un obstacle tel qu'un poteau peuvent être détectées sans difficultés à partir des accélérations du véhicule dans les trois sens, et par comparaison de ces accélérations avec les valeurs de référence prédéterminées.

Title: Process for applying a metallic adhesion layer for ceramic thermal barrier coatings to metallic components
Inventor: FRIED REINHARD
IPC: C23C4/02
Filed: 1996-10-23
Abstract: In a process for applying a metallic adhesion layer for thermally sprayed ceramic thermal barrier coatings (6) to metallic components (1), the surface which is to be coated being cleaned in a first process step, so that the metallic surface is free of grease and oxide, a binder (3) is applied to the metallic surface of the base material (2) in a second process step. Metallic adhesive powder (4) is applied uniformly to the binder (3) in a third process step and solder powder (5), which has a smaller particle size than the adhesive powder (4), is applied uniformly to the binder (3) in a fourth process step. After drying the binder (3), a heat treatment is carried out for the purpose of soldering. The adhesion layers produced in this way are rough and provide a considerable positive lock for the ceramic thermal barrier coatings (6) which are to be sprayed thereon.

Title: A system for securing the flow of and selectively modifying packets in a computer network
Inventor: SHWED GIL
IPC: H04L12/66
Filed: 1996-06-16
Abstract: The present invention discloses a novel system for controlling the inbound and outbound data packet flow in a computer network. By controlling the packet flow in a computer network, private networks can be secured from outside attacks in addition to controlling the flow of packets from within the private network to the outside world. A user generates a rule base which is then converted into a set of filter language instruction. Each rule in the rule base includes a source, destination, service, whether to accept or reject the packet and whether to log the event. The set of filter language instructions are installed and executed on inspection engines which are placed on computers acting as firewalls. The firewalls are positioned in the computer network such that all traffic to and from the network to be protected is forced to pass through the firewall. Thus, packets are filtered as they flow into and out of the network in accordance with the rules comprising the rule base. The inspection engine acts as a virtual packet filtering machine which determines on a packet by packet basis whether to reject or accept a packet. If a packet is rejected, it is dropped. If it is accepted, the packet may then be modified. Modification may include encryption, decryption, signature generation, signature verification or address translation. All modifications are performed in accordance with the contents of the rule base. The present invention provides additional security to a computer network by encrypting communications between two firewalls between a client and a firewall. This permits the use of insecure public networks in constructing a WAN that includes both private and public network segments, thus forming a virtual private network.
