Patent BE-902384-A (BE)
Title: Distress beacon - e.g. for crashed aircraft has automatically inflatable balloon to lift it clear of craft in case of fire
IPC: G08B5/00
Filed: 1985-05-09
Abstract: The balloon remains fixed to the craft by being connected to it by an axial cable. The balloon carries a signal emitter and the cable connector is a conductor so that the emitter can be supplied. The ballon can also have its own current supply e.g. solar collectors, and the signal given out by the emitter can be radio, sound or light waves. - At rest the balloon is held in a covered envelope which also contains the emitter, the cable and a compressed air supply.

Abstract: ABSTRACT Disclosed is a reagent used for serological detection of gonorrheal antibodies in human blood serum or synovial fluid.  The reagent comprises latex particles having absorbed on their surfaces an inert protein, such as bovine serum albumin, and a heat labile antigen derived from Neisseria gonorrhoeae bacteria exhibiting T1 colonial morphology.  The reagent may be employed in several forms, for example, as a liquid suspension of the latex particles, or in the form of a dried deposit of the latex particles.  Regard-less of the form employed, the reagent is particularly useful as a routine screening test in hospitals and prenatal clinics to detect gonococcal infect-ion in women and also in cases of complicated gonorrhea, e.g., gonorrheal arthritis where infection is not conveniently detectable by present means.  If desired, diagnosis made by the test of the invention can be subsequently con-firmed by conventional more expensive and time consuming means, if this is thought to be desirable.

Abstract: METHOD FOR PRODUCING A COAT OF POLYMER      MATERIAL ON METAL PIPES         ABSTRACT     A layer of polymer material is applied to the surface of metal pipe and exposed to a temperature sufficient to bring abou/t the fusing of the layer applied directly on the surface of pipe, this exposure of the layer of polymer material being accomplished in a closed space heat-insulated from the sur-rounding atmosphere. The temperature in said space at the in-stant of introducing therein the tube heated to a temperature c responding to the temperature of polymerization of the polymer material used is maintained above 20°C but not over the tempe-rature of polymerization of the material used. The metal pipe with the fused layer of polymer material is kept in said space for a period sufficient for the polymerization of the layer of polymer material applied and the formation of hard polymer coating on the surface to take place.      Thanks to the present invention it is possible to apply a coat in polymer material to metal pipes using less power than theretofore and obtain coatings providing reliable protec-tion of metal pipes against corrosion.

Abstract: ABSTRACT OF THE DISCLOSURE          A housing enclosing an electrical connector has a cappable open end through which the connector is received and a closed end having a passage that is sealably mounted in al-ignment with a through opening in a pressure hull.  The connector is isolated from a marine environment by a dielectric liquid that fills the housing and immerses the connector.  An end cap closes the open end of the housing to prevent loss and contamination of the liquid and includes a sealable opening through which a first member of the connector is admitted and locked to the housing.          A feed-through portion of the connector mates with the cable end portion and is sealably fitted within the passage to provide an electrical connection through the hull.  In an embodiment for in-line cable connections, the closed end carries a second member of the connector, corresponding to the first member, which is locked and sealed in the passage.  A bleed hole in the housing communicates the environment to the liquid which pressurizes the housing and seals the connector to prevent corrosion.  The bleed hole also operates to relieve pressure within the housing caused by expansion and contraction of the liquid due to environ-mental temperature changes.

Abstract: ABSTRACT OF THE DISCLOSURE            This invention relates to a device for crimping conductors into the contact members of a contact strip.  Known devices of this type are designed so that one full operational cycle follows another in a predetermined constant sequence.  The problem encountered with this design is that the time available to the operator for inserting the conductor into the terminal section of the contact member is fixed by the design of the device and is usually very short.  A new operator would thus have difficulty in learning, as well as an experienced operator at the beginning of each week period.  If the time allowed to the operator for inserting the conductor is set to the maximum time required, the device is not used efficiently.  Furthermore, in known devices, the motion of the device cannot be stopped once a working cycle has been initiated.  The present invention provides a crimping device which is free of the shortcomings outlined above.  According to the invention there is provided a motor driven means for two crimp-ing jaws movable relative to each other, and feeding means for step-wise advancing the contact strip in increments corresponding to the distance between the contacts to feed one contact to the crimping jaws in each operational cycle.  An actuating device, which can be controllably manipulated by the operator, actuates the feeding means advancing the contact strip and, in a second position, effects the crimping operation and the return of the feeding means to the initial position.
