Inventor: RICK ROBERT
IPC: B29C45/32
Filed: 2003-11-12
Abstract: Selon cette invention, une buse englobante (10) est constituée de deux pièces (22,24) qui, assemblées, forment un logement (20) traversé d'un passage (30), un siège de soupape conique (50) entourant le passage et un élément de soupape (60) possédant une tête de soupape conique (62) venant dans le passage de façon à s'engager dans le siège de soupape. Les deux pièces (64,66) sont séparables axialement au niveau d'une interface (68) entre le siège et la tête. L'ouverture du robinet se fait par l'assemblage et le déplacement en bloc des deux pièces dans un même sens par rapport au logement, s'éloignant axialement du siège de soupape. De façon similaire, les éléments de soupape sont ramenés simultanément de façon à être mis en contact avec le siège de soupape avant la séparation de la buse englobante. En conséquence, à la différence du modèle de soupape à clapet, l'interface entre les deux pièces de la tête de soupape n'est pas exposée à une résine fondue et la résine fondue n'est pas piégée entre les deux pièces, laissant une marque à l'ouverture.

IPC: B01J20/20
Filed: 1990-05-01
Abstract: ABSTRACT OF THE DISCLOSURE           Activated carbon is used in gas-mask canisters for filtering air to remove toxic vapours.  For military use, the charcoal is impregnated with inorganic salts or organic compounds for improving the chemical activity of the charcoal with respect to toxic vapours having low boiling points and small molecular sizes, e.g. cyanogen chloride.  One such compound, namely triethylenediamine (TEDA) has been added to charcoal by sublimation at atmospheric pressure.  A more effective method of impregnating charcoal with TEDA utilizes reduced pressure 0.13 to 13 Pa, preferably 1.3 Pa as a driving force to facilitate vaporization of the TEDA by sublimation.          The activated carbon to be impregnated is dried at 110°C to 160°C for three hours and transferred to a vacuum desiccator.          The required amount of the amine, namely 1.57 to 12.57%, preferably 4.7% is placed in the container on top of the activated carbon and the container is evacuated to a pressure of about 1.3 Pa and heated at 40°C for two to three days until the amine compound is no longer visible on the carbon.  The resulting TEDA impregnated carbon provides improved protection against toxic gases compared to the precursor charcoal.

Abstract: ABSTRACT    In a ground fault detector for long distance sub-scriber lines accommodated in a small capacity digital electronic exchange, a DC/DC converter for power supply is stopped during detection of ground fault.  Upon reception of the stop signal, the DC/DC converter con-verts the power supply voltage for the subscribers to a voltage as the system power supply of the exchange, namely to a low voltage before voltage conversion of the DC/DC converter.  The battery feed circuit can maintain the alarm condition, even if a current flows continuously to the battery feed resistor due to a ground fault, until the ground fault is re recovered by the maintenance person without breaking the resistor.

Abstract: In a key telephone system connectable  to both ISDN and  PSTN,  for  the  purpose  of  compensation  of  a difference in speech signal level between ISDN and PSTN, digital pads are incorporated in an ISDN interface unit mounted on a key service unit of this system.   In the digital  pads,  original  PCM-code  speech  signals received/transmitted from/to the ISDN line are converted into PCM-code speech  signal with a  compensated speech signal level obtained by adding a selected gain to the original speech signal level.   Since the difference in the speech signal  level between ISDN and PSTN differs according  to  the  conditions,  an  appropriate  gain  is selected from a plurality of previously prepared gains. That is, the relationship between telephone numbers and information signals indicative of the selected gain is registered  in  the  key service  unit.   Therefore,  when conversation  is made  to  a  subscriber  whose  telephone number  has  been  registered  through  the  ISDN, a  gain registered  in  correspondence  to  the  subscriber's telephone number can be selected automatically.

Abstract: A microwave oven with an invertor control power source produces a microwave by the use of a magnetron in combination with high frequency power generated by an invertor control power source.   Heat sensitive ferrite beads provided on a lead wire for transmitting the high frequency power to the magnetron changes the inductance of the wire from a high level to a low level at around a threshold temperature,  which is lower than the working equilibrium temperature of the magnetron.  As a result, the cathode  filament  current  remains  within the  allowable range, and moding of the magnetron is prevented.  Thus the lifetime of the magnetron is lengthened.

Abstract: A crimpless coaxial cable connector is provided which can be secured to a cable simply by pushing the cable into the connector and subsequently pulling it back. The body of the connector has a bushing mounted within it near the cable receiving end having a diameter to closely receive the cable.   The body of the connector also has within it an annular mandrel having a bore to receive the stripped core of the cable, and having a sleeve adapted to engage the cable beneath the jacket by pushing the cable and the mandrel together.  This stretches the jacket of the cable to a diameter greater than the internal diameter of the bushing.  The mandrel is movable from a position in which the sleeve is not surrounded by the bushing in which the sleeve may be engaged to the cable, to a position in which the sleeve is at least partially within the bushing in  which  the  jacket  is  frictionally  engaged  by  the bushing, by pulling the cable away from the connector after  it  has  been  pushed  onto  the  mandrel  sleeve. Preferably, the mandrel is displaced to further tighten the frictional engagement of the jacket by the bushing by screwing the connector onto a threaded coupling unit.
