Abstract: Abrégé Dispositif de réduction de la gigue due aux sauts de pointeurs dans un réseau de télécommunications numériques. Le dispositif comprend un circuit d'insertion pour insérer, au voisinage de chaque saut de phase du à un saut de pointeur, une pluralité de sauts de phase de lissage, selon un motif de lissage déterministe, pour éliminer, après passage dans un désynchroniseur conventionnel, les effets de la quantification des sauts de phase. Il est également prévu, dans le cas où chaque saut de phase dû à un saut de pointeur comprend une pluralité de bits, un circuit de commande pour décomposer ce saut en une pluralité de sauts élémentaires et commander l'insertion de ces sauts de façon adaptée a la fréquence d'apparition des sauts de pointeur.

Title: Process based on circulating fluidized bed technique for cooling gases, and a circulating fluidized bed cooler used in the process
Inventor: RUOTTU SEPPO
IPC: B01J8/44
Filed: 1991-12-30
Abstract: Abstract The invention relates to a process for cooling gases using a circulating fluidized bed technique, wherein gas  is conveyed through a fluidized bed formed by circulating fluidized bed material so that part of the  circulating  fluidized  bed  material  is  driven along with the gas flow and whereby the circulating fluidized bed material entrained in the gas flow is separated  from the gas  flow and returned into the fluidized  bed,  and  wherein  at  least  part  of  the cooling  is  carried  out by cooling the  circulating fluidized bed material  stream to be  returned.  The process is characterized in that  substantially the entire cooling is realized by cooling the circulating fluidized bed material  stream to be returned in a heat exchanger (10) separate from the gas flow duct, in which  event  the  cooling  of  the  gas  stream  is effected by means of the circulating fluidized bed material  stream returned to the  fluidized bed  and having a temperature lower than that of the fluidized bed.

Patent CA-2062821-A1 (CA)
Inventor: BOROS FERENC
IPC: H01R25/14
Filed: 1991-04-17
Abstract: The contact properties of plug elements deteriorate even with slight twists.  By using elastic intermediate, current-transmitting elements, a relative insensitivity to twists is obtained.  In order to reliably secure the intermediate elements to bearing or current-carrying-off elements, however high costs are incurred. In order to eliminate the disadvantages of the state of the art and to obtain good contact properties with a reliable fastening, the contact bars are imbedded in a plug shell in such a way that they are located in window-like openings and engage slots by their edges. The current is led by contact tabs that protrude from the plug shell. The plug shell in composed of two identical halves which may be interconnected by interlocking and by adherence without any additional fastening elements. With these plug elements, a reliable contact of busbars is easily obtained and it becomes possible to supply with load current plug-in racks of distribution boards with plug-in racks and reduced plugging forces.     Besides other advantages, this plug element is rugged and easy to mount.
Patent CA-2063922-A1 (CA)
Title: Selective transmission of encoded voice information representing silence
Inventor: WILSON ALAN L
IPC: H03G3/34
Filed: 1992-03-25
Abstract: Discrete packets (306) containing encoded voice information are transmitted within frames (301 and 302) in a repetitive manner until all voice information has been sent. Following transmission of all packets containing such voice information, at least a predetermined number of additional packets (401) are then transmitted, which additional packets represent silence. Following this, a disconnect signal (304) is transmitted. So configured, loss of the disconnect signal due to fading or other communication pathway disturbances will not necessarily lead to audibilization of undesired sounds, as the decoding protocol at the receiver (200) provides for reprocessing of recently received packet information in the absence of newly available reliable information. Hence, the silence information is continually reprocessed until either reliable information is again available or a time out sequence concludes.

Abstract: Docket 7435 TORQUE LIMITING CLUTCH     Abstract of the Disclosure A hub member receives a tapered collet for gripping a drive shaft such as a shaft projecting from an electric motor.  The hub member extends into a surrounding cylindrical housing which is secured to rotate with the hub member and carries a set of generally square clutch plates.   An annular drive member is supported for relative rotation by the hub member and has an inner portion projecting into the housing to support a set of annular clutch disks which  interfit between the clutch plates.   The housing encloses oil which circulates between the clutch plates and disks, and a set of rotary seals confine the oil within the housing while providing for rotation of the drive member relative to the hub member and housing.  The drive member has external teeth for driving a load through an endless belt or gears, and the housing encloses a set of compression springs which normally urge the stack of clutch plates and disks together for transmitting a selectable maximum torque from the drive shaft to the drive member through the hub member and housing.

Title: Grease gun auto-pull follower apparatus
Inventor: HUSMAN DAVID N
IPC: B05C17/005
Filed: 1992-08-07
Abstract: Abstract of the Disclosure An auto-pull follower is provided for use in a grease gun of the type having a grease reservoir with a piston mounted for reciprocating movement in the reser-voir.  The piston is moved in a first direction through the reservoir interior to enable loading grease into the interior or to permit insertion of a grease containing cartridge or collapsible container into the interior, and the piston is moved by a piston spring in the opposite direction through the reservoir to dispense loaded grease from the reservoir interior or from the grease cartridge or collapsible container contained in the interior.  The reciprocating piston is provided with a novel auto-pull mechanism comprising a spring biased spool mounted for rotation on the piston, and a flexible cord or chain extending from the spool and out of the reservoir through a hole in a rearward end wall of the reservoir.  Pulling the end of the cord outside the reservoir causes the spool to rotate against the bias of the spool spring and causes a length of cord to be unwound from the spool. After unwinding the length of cord from the spool, con-tinued pulling of the cord from the reservoir end wall causes the piston to move against the bias of the piston spring in a direction towards the reservoir end wall. The movement of the piston toward the end wall increases the interior volume of the reservoir and enables the loading of grease into the reservoir interior.  Releasing the cord causes the spring bias of the spool to auto-matically retract the length of cord pulled from the reservoir interior back into the reservoir interior and rewinds the length of the cord back on the spool.
