IPC: H04W84/04
Filed: 1992-04-21
Abstract: Un système de radiotéléphonie cellulaire AMRC (FIG. 2) a des systèmes de commutation (201) synchronisés avec les signaux de synchronisation (600) du réseau téléphonique public (100), et des radiotéléphones (203) et des stations cellulaires de base (202) synchronisés avec une horloge différente (1000). Les temps de transmission entre les stations cellulaires de base et le réseau téléphonique varient. Les systèmes de commutation comprennent des interfaces numériques (264) avec le réseau téléphonique, dont les connexions au réseau téléphonique sont synchronisées avec le réseau téléphonique et dont les connexions avec les cellules sont nominalement synchronisées avec le réseau téléphonique, mais dont le processeur (602) fonctionne, pour chaque appel, à l'intérieur de fenêtres prédéfinies (1302, 1402) de rapports de phase avec l'exploitation de la cellule qui traite l'appel, et règle occasionnellement (FIG. 13-16) ses rapports de phase avec l'exploitation du réseau téléphonique pour réaliser et maintenir son fonctionnement à l'intérieur des fenêtres prédéfinies. Les transmissions avec commutation de paquets (350) entre les cellules et les systèmes de commutation absorbent les variations de rapports de phase et les réglages de synchronisation dans les intervalles interpaquets. Les transmissions numériques avec commutation de circuits entre les systèmes de commutation et le réseau téléphonique absorbent les réglages de synchronisation de glissements (insertion ou suppression de bits), produits par vocodeur (604), dans le flux binaire du trafic de communications.

Title: Device for automatically clamping on the pole of a shaft trolley, a grasped element to which a shaft is suspended
Inventor: LEBRE CHARLES J P
IPC: F16B7/04
Filed: 1992-07-24
Abstract: The upper and lower jaws are joined to a double yoke surrounding the pole.  An auxiliary yoke imprisoning a clamping plate is slidingly mounted on the pole above the double yoke and is connected to the latter by means of a compression spring.  On the yoke, a connecting rod is slidingly mounted and joined at its intermediate portion to a thrust lever having one extremity joined to the auxiliary yoke and engaging the clamping plate.   The weight of the shaft transmitted by the jaws to the double yoke automatically pushes the lever onto the plate and thus immediately immobilizes it by clamping the device along  the pole.    Activation  of  the  spring  controls clamping of the plate in the absence of any load, whereas a push applied along a predetermined direction on the handle of the lever annuls the action of the spring and allows the device to slide freely.   The invention is applicable to trolleys ensuring suspension of shafts for their handling operations.

Title: Method of generating process heat
Inventor: KELLER JAKOB
IPC: F23D3/02
Filed: 1992-11-18
Abstract: ABSTRACT OF THE DISCLOSURE    In a method of generating process heat, a process medium is heated in two stages to its final temperature in   a   process   heat   generator   (100).      Under-stoichiometric combustion is undertaken in the first stage as pre-combustion zone  (107)  which is located downstream of a burner device  (101).   Downstream of this pre-combustion zone  (107), the combustion gases pass through a cooling phase which takes place by means of a heat exchanger (108).  Further downstream of the heat exchanger (108), there is a reheat zone (110) and air  (109)  fed  into  this  region  is  supplemented by cooled exhaust gas (112).  This exhaust gas (112) can be introduced before the air (109) supplied or together with the latter in the region of the reheat zone (110). A further heat exchanger (111) is located downstream of the reheat zone (110).  Because the exhaust gases (115) are  branched  off  after  the  further  heat  exchanger (111), the latter has an effect on the combustion tem-perature in the reheat zone (110).  In order to avoid thermal overloading of the combustion chamber walls in the pre-combustion zone  (107), the air supply  (106) takes place in a counter-flow convective heat exchanger (105)  which preheats the air  (106)  supplied to the combustion air (15) and, on the other hand, cools the combustion chamber walls.   The first heat exchanger (108)  extracts only a part of the heat which should have been extracted to achieve the optimum temperature range,  to minimize the NOx emissions,  in the reheat zone  (110).    This  is  possible  because  the  latter combustion zone is fed with cooled exhaust gas.   In this way, it becomes possible to reduce the relative heat extraction in the pre-combustion zone (107) by any required amount and this improves the economy of the installation.

Title: Interference microscope
Inventor: DABBS TIMOTHY PETER
IPC: G02B21/00
Filed: 1991-08-30
Abstract: Methods and microscopes for measuring the difference(s) between at least two energy path lengths are disclosed. According to one embodiment a confocal interference microscope (100) may be employed to build up an interferogram of surface (123) of object (124) as follows. A portion of the light beam from coherent laser diode (101) is coherently guided to exit (115) and focussed into a diffraction limited spot (125) intersecting surface (123) by high quality lens (122). A portion of the scattered signal light resulting from spot (125) is collected by lens (122) and confocally injected back into exit (115) to be guided back to coupler (108). A  second portion of the light beam from diode (101) is coherently guided to end (121) from whence it emerges collimated. This collimated beam termed the reference beam is partially reflected by mirror (126) through end (121) and is guided back to coupler (102) where it interferes with the signal beam. The result of the interference is detected by detector (127) and fed to computer (128). A  portion of the signal light injected into fibre exit (115) is guided to detector (145) which detects the intensity level. This intensity level is fed to computer (128) and used to control scanner (130) so as to maintain the focus of spot (125) on surface (123).  A portion of the reference beam reflected by mirror (126) is injected into single mode fibre (135) and guided coherently to coupler (138) where it interferes with illuminating light guided coherently from laser diode (101) and hence detected by detector (142). The resulting signal is fed to computer (128). While scanner (130) is moving the exits computer (128) keeps track of their position by monitoring the interference signal from detector (142).
