Patent CA-2228657-A1 (CA)
Inventor: VAN SCHYNDEL ANDRE JOHN
IPC: H04M1/03
Filed: 1996-01-10
Abstract: L'invention concerne une configuration de montage pour microphone de combiné classique ou suspendu autour du cou et autre, ayant une extrémité d'émission et une extrémité de réception. L'extrémité d'émission comporte une cavité de forme régulière prévue pour une capsule de microphone à vitesse de rang supérieur, avec deux ou plus de deux pôles. La capsule est fixée symétrique de sorte que son centre géométrique corresponde sensiblement au centre géométrique de la cavité. La taille de la section transversale de la capsule est inférieure ou égale à la profondeur de la cavité. Ainsi, la capsule est encastrée dans la cavité, elle-même recouverte d'un écran transparent du point de vue acoustique. Un espace est ménagé entre les pôles du microphone et les faces de la cavité pour donner l'impression que le microphone est en espace libre.

Title: Drive source for fire fighting apparatus
Inventor: SUNDHOLM GOERAN
IPC: A62C35/02
Filed: 1998-03-11
Abstract: The invention relates to a drive source for a fire fighting apparatus comprising spray heads, the drive source comprising a hydraulic accumulator, which comprises a container with extinguishing liquid and a pressure gas source for driving the extinguishing liquid out of the container via a channel to the spray heads. To prevent icing of extinguishing liquid in the container and to make the droplet size small, the drive source is characterized in that the container comprises in its lower part an outlet for conducting extinguishing liquid via the channel out to the spray heads of the fire fighting apparatus, and the container is connected to a liquid container having a rising tube in such a way that the rising tube is arranged to conduct extinguishing liquid to a place in the channel, whereby the resistance to a liquid flow via the rising tube has been made stronger than the resistance of the channel to the liquid flow, and that the liquid container is connected via a conduit to the pressure gas source in order to obtain gas pressure from the pressure gas source, whereby a nonreturn valve is arranged in the conduit to prevent liquid from flowing from the liquid container to the pressure gas source.

Title: Protected programmable memory cartridge and computer system using same
Inventor: COMBS JAMES LEE
IPC: G06F13/00
Filed: 1994-08-26
Abstract: A computer system for high-performance video and audio manipulations comprising a locked memory cartridge and an audio/video/compact disk (CD) drive controller/coprocessor. The computer system has a central processing unit (CPU) with at least one bus associated therewith, with the bus having at least one bus line. The cartridge comprises a readable memory, a memory control circuit, a lock control circuit, and a connector all in circuit communication with each other. The connector allows the memory, the memory control circuit, and the lock control circuit to be pluggably connected in circuit communication with the CPU. The memory control circuit scrambles some of the bus lines, thereby scrambling the data in the memory on reset, and unscrambles the bus lines responsive to inputs from the lock control circuit. The lock control circuit monitors the bus, waiting for a proper combination of bus values to be asserted onto the bus, at which time the lock control circuit causes the memory control circuit to unscramble the bus lines. The audio/video/CD drive controller/coprocessor comprises a CPU interface, a CPU cache, a memory controller, a memory bus arbitrator, a DRAM refresher, a video controller, a CD drive controller, a digital signal processor (DSP) sound coprocessor, and a "blitter" graphics coprocessor in an integrated package.

Patent CA-2237264-A1 (CA)
Title: Receiver based congestion control
Inventor: SEDDIGH NABIL
IPC: H04Q11/04
Filed: 1998-05-08
Abstract: In a packet network, on receiving a packet a receiving host determines if the packet has been marked by any of the nodes through which it passed, to indicate congestion at that node, e.g. by checking the CE bit in an IP header. A packet flow control parameter is generated at the receiving side, and sent to the source using an Internet Protocol, as part of the packet acknowledgment, to control the flow of packets from the source, according to the packet flow control parameter. This can reduce control loop delays caused by waiting at the source for a number of acknowledgments to arrive before the congestion level can be calculated. Conditions at the receiver which may be different to those at the source can now be taken into account in the flow control.

Abstract: L'invention porte sur un appareil et sur le procédé de moulage d'un article conchiforme dans un moule permettant de mouler au-dessus de la plaque de moulage et donc "hors du moule". L'appareil comporte un élément de moulage souple placé dans la cavité d'un moule pour repousser le matériau liquide de moulage de la cavité dans l'espace compris entre la surface de moulage de la cavité du moule et l'élément de moulage. Autour de chacun des éléments de moulage se trouve un moyen de confinement en contact avec la surface supérieure de la plaque de moulage au niveau du bord de la cavité du moule pour maintenir le matériau entraîné au dessus de la plaque de moulage. Il est prévu un canal associé au moyen de confinement, à l'élément de moulage ou la plaque portant l'élément de moulage, dans lequel le matériau liquide de moulage s'élevant au dessus du niveau du sommet de la plaque de moulage pénètre et puis se trouve contenu par le moyen de confinement. Après solidification du matériau liquide de moulage, on obtient un article moulé conchiforme dans lequel une partie ou la totalité du bord supérieur est moulée au dessus du niveau de la plaque de moulage. L'invention porte également sur les articles obtenus au moyen de cet appareil et sur le procédé objet de l'invention.
