Abstract: An analyzer (10) for detecting a selected chemical (such as oxygen) in a process fluid includes a plurality of electrodes (12, 14, 22) that are separated from the fluid by a membrane (18) that is permeable to the selected chemical, each of the electrodes (12 14) when energized producing a signal in response to the selected chemical in the fluid. The selected chemical level in the process fluid is determined based on the signal produced by a first one of the electrodes (12) and the determined level is used with the signal produced by a second one of the electrodes (14) to detect whether the membrane (18) has become faulty (e.g., fouled by ma-terials in the process fluid).

Abstract: A packet transmission method and apparatus prevents the holding of unavailable links daring packet transmission.      An embodiment of the present invention assumes the case of a packet transmission between a transmitting terminal and a receiving terminal over a path which includes seven links and six switches. The third and fifth switches provide first and second intermediate burst servers which have a buffer for temporarily holding a message packet and a function of the packet transmission. The function comprises requesting a link reservation, transmitting a message packet, storing a received-message packet, and releasing reserved links upon completing the transmission of the message packet. When the transmitting terminal transmits a message packet, a first end burst server starts the packet transmission including the link reservation to the first intermediate burst server, and when the packet transmission is completed, reserved links between those burst servers are released. The same packet transmission is repeated consecutively to each burst server up to the receiving terminal, if the link reservations are not blocked. If a link reservation is blocked, the packet transmission is held at the latest burst server, and either another link reservation of the same bandwidth is used or the transmission is converted to use another available bandwidth.

Abstract: A mass analyzer system uses a dual mode electron multiplier detector which outputs both a pulse count and an analog signal. Depending on the ion flux intensity, the signals define a pulse count only region in which the pulse count only signal is valid, an overlap region in which both the pulse count and analog signals are valid, an analog signal only region in which only the analog signal is valid, and a neither analog nor pulse region in which neither signal is valid. The system produces a separate flag for each region. When a mass spectrum is scanned, for each dwell the pulse count and analog data are recorded together with their associated flag and are placed in memory. The signals, with the flags, can then be used to produce a mass spectrum using the pulse count only signal, the analog only signal, or both. In addition numeric displays can be produced for each peak or a variety of peaks, using the pulse count only signal, the analog signal, or both, together with a display of the flag or flags which have been set at the peak being displayed.

Abstract: A conveyor chain manufactured from plastic, which is adapted to move at higher speeds than has been conventional heretofore and which is consequently particularly suitable to be used in a conveying system together with a conveyor mat to take over products from this mat or feed them to it.  The chain has as a specific property that the front edge and the rear edge of the bearing surface of the chain link are of curved, preferably elliptically-shaped, design in the plane of the bearing surface, that the single hinge eye at the rear edge of the bearing surface has an upper surface which extends in the same plane as the bearing surface and which engages through a convexly shaped end in a correspondingly shaped recess in the bearing surface of the adjacent link coupled thereto through the hinge pin. By these measures the transition of products to and from the chain proceeds extremely smoothly at high speeds too.

Title: Outdoor structure such as gate post, gate wing or fence and method for constructing this
Inventor: SUGIYAMA SHIGEYUKI
IPC: E04H17/14
Filed: 1995-12-29
Granted: 2001-08-21
Abstract: The invention aims to make outdoor structure such as gate post suitable for mass production by achieving weight reduction of such structure so that the structure can be manually  transported,  installed,  on  one  hand,  and  by facilitating adhesive fixation of artificial stones,  on the other hand.      Artificial stones 10 are molded in a predetermined number  of  different  shapes and  a  substrate  20  is expansion-molded  from  foam  plastics.  Artificial  stone receiving  recesses  22  are  molded  integrally  with  the substrate  20 so  as  to  be  paired  with  the  respective artificial  stones  10.  The  artificial  stones  10  are adhesively  inserted  into  the  corresponding  receiving recesses  22  so  that  such  insertion  may  serve  as provisional  fixation  means  to  prevent  the  artificial stones 10 from scaling off or falling off before setting of  adhesive  agent.  A  protruding  rib  21  bordering  and defining    the  respective  artificial  stone  receiving recesses 22 serves also as a joint base adapted to support the overlying joint mortary 23. In this manner, adhesive fixation of the artificial stones 10 is facilitated,  on one  hand,  and weight  reduction of  the  gate post  A us achieved by employing foam plastics as material for the substrate 20, by making the protruding rib 21 serving also as the joint base supporting the overlying joint mortar 23 and consequently by saving an amount of the joint mortar 23 to be used.

Abstract: A shelf for housing printed circuit boards in which a back plane has an extension in the form of a back plane extender printed circuit board electrically connected to the back plane and extending forwards from the back plane at one side of the shelf.  In a location forwardly of the back plane, the extender printed circuit board carries a connector structure which extends outwards from the extender printed circuit board and has connectors outwards from the extender printed circuit board.  These connectors are accessible either from the front or rear of the shelf dependent upon connector orientation.  This structure avoids the need for connectors on the rear face of the back plane thus allowing for the back plane to be located further to the rear and permitting increase in size in circuit boards to be mounted within the shelf.  The connector structure is preferably detachable so as to permit its replacement with a different design of connector structure.  The connector structure may include its own printed circuit board which when changed for a board of different design may change the operation of the total circuit board arrangement including the back plane.

Abstract: A method and a device are provided for disposing of an aqueous solution than contains an organic acid and an iron complex and occurs particularly in the decontamination of radioactively contaminated surfaces of components. It is contemplated that the iron complex in the solution is reduced by irradiation with UV light. A dissolved iron salt and carbon dioxide, which is given off, are formed in the process. A oxidant is then added to the solution that contains the dissolved iron salt and the organic acid. This produces water, and the iron complex foams once again. Some of the dissolved iron salt is removed from the solution by means of a cation exchanger. The solution containing the iron complex is irradiated again with UV light. A cycle process ensues, which continues until all the organic acid is consumed.

Abstract: Paint flow control interface circuitry for passing electrical signals across a paint booth barrier including a feedback signal indicating a paint flow parameter from a parameter transducer within the paint booth, includes passive resistive intrinsically safe barrier circuit elements coupled with buffer circuitry for minimizing the voltage drop across the interface circuitry. Light filtering of the buffer circuitry output signal with minimum filter lag yields an accurate indication of the paint flow parameter with high signal to noise ratio and minimum signal lag, for application in closed-loop paint flow control. Additional transducer voltage supply signal feedback provides for closed-loop voltage supply control across the interface circuit.
