Title: Procede et dispositif pour detecter et interpreter  un signal de detresse
Inventor: ROGARD ROGER
IPC: H04B1/034
Filed: 1980-02-05
Granted: 1982-09-07
Abstract: Les signaux de détresse sont transmis de façon répétée en séquences successives composées chacune d'un intervalle de détection pendant lequel est transmis un signal d'alarme et d'un intervalle de transmission de message pendant lequel est transmis le message de détresse proprement dit indiquant notamment l'identité du bateau en détresse, sa position et le type de détresse. Pendant l'intervalle de détection, le signal transmis est constitué d'une porteuse modulée en phase par une sous-porteuse, la fréquence de celle-ci étant un multiple de la vitesse de transmission de l'information.  Pendant l'intervalle de transmission de message, l'information est superposée à la sous-porteuse par modulation binaire de phase.  La présence d'un signal d'alarme pendant chaque intervalle de détection est détectée dans un récepteur d'alarme surveillant la bande de fréquences de réception simultanément dans plusieurs canaux de largeurs de bandes étroites distinctes afin de produire un signal de commande qui indique la présence d'un signal de détresse dans un canal quelconque.  En réponse à ce signal de commande, le signal de message reçu pendant l'intervalle de transmission de message subséquent est contrôlé de façon précise, puis démodulé et interprété de façon cohérente dans un récepteur de message afin de restituer le message de détresse.

Abstract: ABSTRACT OF THE DISCLOSURE         A game is disclosed which includes a generally planar playing surface, a top and a top spinning means for spinning the top and directing the spinning top onto the middle of the playing surface.  The game includes a pair of oppositely disposed siderails which define a playing field on the playing surface.  The siderails include edge portions which deverge from each other from a midfield position to the opposite ends of the playing surface, with the siderails being configured for impact with the spinning top to change the direction of movement of the spinning top.  A goal area is provided adjacent each end of the playing surface for receiving the spin-ning top during game play, and manually operable blocking means the playing surface and each goal area are provided for enabling a player to redirect the spinning top towards the opposite end of the playing surface.

Abstract: ABSTRACT OF THE DISCLOSURE        A cartridge extractor, comprising a resilient ring segment 21 formed with a claw 30, is mounted without a rivet in a recess 15 in the face of a firearm bolt 22.  The bolt recess is formed with an arcuate clearance cut 31 and with radius cuts 27, 28 at either end of the clearance cut.  The extractor ring has its free ends bent to form detent arms 23, 24, which seat in the radius cuts to support the claw in position to engage a cartridge case 29 as it enters the recess.  This entry deflects the ring into the clearance cut.  When the claw seats in the base of the cartridge, the ring is repositioned by the detent arms sliding back into the radius cuts.  A pin 35, or other means 38, 43, or 48 may be added to prevent relative rotation of the extractor ring, without interfering with its normal deflection.

Abstract: "ICE  PROTECTED  RUDDER"                            ABSTRACT            A major restraint attending the navigation of ships in ice arises from the vulnerability to ice damage of appendages vital to navigation such as propeller(s) and rudder(s). This invention protects such vital appendages from unrestrained contact with ice and limits the size of such ice pieces as may contact them to proportions which can be comminuted by the propeller and will not submit the appendages to catastrophic damage such as might hazard the ship.

Abstract: Abstract of the Disclosure An optical waveguide filament comprising a cladding layer, a core and a barrier layer disposed between the core and cladding.  The barrier layer comprises silica doped with B2O3, P2O5 and GeO2.  The core consists of an inner region and an outer region, the boundary between which is referred to as the core break-point.  In the outer region of the core, the concentration of B2O3 de-creases linearly from its barrier layer level to zero at the core break-point, the P2O5 increases at a rapid rate from the barrier layer level to a first concentration level at the core break-point and the GeO2 remains at a constant value between zero and the barrier level.  In the outer region of the. core, the GeO2 increases from some level up to the barrier layer level to a greater value at the filament axis in a power law fashion.  The P2O5 also increases in a power law fashion from the value thereof at the core break-point to a higher value at the filament axis, the increase in concentration of P2O5 in the outer  core region increasing at a rate greater than the concentration of P2O5 would increase if the power law P2O5 gradient extended into the outer core region.

Abstract: ABSTRACT In the formation of a metal or metal compound coating on a face of a heated glass substrate during its forward displacement along a tunnel by contacting the substrate at a coating station in the tunnel with at least one stream of droplets comprising one or more substances from which the coating is formed, and simultaneously exerting suction forces in exhaust ducting to draw environ-mental gases away from that station, the coating may some-times be spoiled by side reactions or by the spurious deposition of substances from the atmosphere within the tunnel. To help reduce this spoiling, the exhaust ducting comprises at least one exhaust duct whose entrance is located in the tunnel forwardly or rearwardly of the coating station and which forms or is associated with a barrier wall located so as to prevent gases from passing over the duct, towards and into contact with the droplet stream(s).
