Patent EP-0516701-A1 (EP)
Title: Video telephone system.
Inventor: BUSH DANIEL R
IPC: H04N21/61
Filed: 1991-02-14
Abstract: Apparatus and method are provided for the simultaneous transmission of video information and audio information in substantially real time over an ordinary voice grade telephone line having limited bandwidth in the range of about 300-3400 Hz. Because of the limited bandwidth of the ordinary telephone line, the video and audio information are compressed before transmission thereof. Each of the video information and audio information is separately compressed, mixed together and then further compressed. After the further compression, a composite signal, which includes the mixture of video and audio information, is asynchronously transmitted over the same bandwidth of the ordinary telephone line. Upon reception, the compressed information is expanded and separate video information and audio information are reproduced for viewing and hearing by the receiving party. To reduce the size of the apparatus, application specific integrated circuits (ASICs) are employed. A state machine controller apparatus is integrated with the ASIC technology to control the transfer and storing of video information and audio information and also to control the operation of the various compression and expansion stages associated with the transmitting and receiving channels.

Title: Machinability improving supplementary powder and iron or steel powder containing such supplementary powder.
Inventor: ENGDAHL PER
IPC: B22F1/00
Filed: 1991-03-18
Abstract: A machinability improving and/or wear-resistance improving supplementary powder for an iron- or steel-based powder for use in powder-metallurgical production of blanks consists of MnS and Te or a Te-compound and/or Se or an Se-compound. For the supplementary powder, an iron or steel powder containing the same and a blank which is powder-metallurgically produced from the iron or steel powder, the weight ratio between MnS and Te should be in the range of 10-2000, the weight ratio between MnS and Se should be in the range of 10-1000, and, when both Te and Se are used, the limiting values of this range should be doubled.

Abstract: Traversée (2) pour fibre optique dans laquelle une fibre (6) de maintien de polarisation (PM) est scellée dans une gaine métallique (14) au moyen d'un scellement (20) en verre. Le scellement (20) applique des contraintes asymétriques à la fibre (6) orientée de façon que ces contraintes renforcent ses propriétés de maintien de polarisation. Ce dispositif réduit les tolérances de fabrication nécessaires pour éviter de détruire les propriétés de maintien de polarisation d'une fibre associée à des scellements produisant une contrainte symétrique. Il s'applique aux boîtiers de composants opto-électroniques. L'invention se rapporte également à une double traversée pour fibre optique.

Abstract: A rinse nozzle for an aircraft waste tank includes a tubular member mountable at one end in an opening in the waste tank for receiving cleaning solution through said one end to the interior of the tubular member. The other end of the tubular member extends into the tank and is closed to prevent the exit of cleaning solution out that end. The tubular member has a midsection (32) with a reduced radius and a plurality of first openings (36) circumferentially spaced apart around the midsection. Ann annular collar (40) is rotatably disposed about the midsection of the tubular member and includes a plurality of second openings (64) disposed thereabout, at least some of which extend outwardly and rearwardly of the direction of rotation of the annular collar to thereby cause the collar to rotate as cleaning solution flows from the tubular member out the first openings against the collar and then out the second openings. A retainer ring (52) is positioned about the tubular member below the midsection to support and hold the collar on the tubular member about the midsection.

Abstract: The invention is related to hot plugging of an electrical circuit (1) into a separate non-quiesced signal net (6) in an active system (7), such as a digital or analog bus. The inventive solution proposes the addition of a preconditioning network (4) to precondition the electrical circuit (1) to be hot plugged by partially precharging the parasitic input capacitances (C c , C e , C m ) of the electrical circuit (1) before hot plugging. The precharging of the parasitic input capacitances serves to minimize transient effects on the active system (7).

Abstract: The invention relates to a storage device which is connected on the entry side and exit side to the transport system of the winding machine and which has a cop-attachment position. 
<??>The object of the invention is to develop a storage device of this type in such a way that, whilst requiring only a small amount of space, it has a high storage capacity and the cop attachment is possible under ergonomically advantageous conditions for the attendant. 
<??>This object is achieved, according to the invention, in that the storage device possesses a plurality of mutually independent storage zones (9 to 14) receiving in assorted manner caddies (1) with bobbins (4) and empty caddies (1), the storage zones (9 to 14) being connected on the entry side and exit side to respective common transport zones (8, 77). Switching means (79 to 84, 16 to 21) for the controlled entry and exit of the caddies (1) are arranged on the storage zones. A storage control device (74) can select the storage zones (9-14) on the entry side and exit side. The transport zone (8) connected on the exit side leads to the bobbin delivery path (5) of the winding machine. The cop-attachment position (43) is advantageously arranged on the zone (8') from the common transport zone (8) connected on the exit side to the bobbin delivery path (5).

Abstract: A process for forming an easy-opening arrangement for gable-top cartons is described. A tape is applied to the inside of the pouring spout in order to stiffen the panels, while reducing the force required to separate the thermoplastic seal. The tape is bonded to the thermoplastic surface layer of the carton by an adhesive. During the hot air heating of the carton top prior to sealing, the area where the tape is located is not exposed to the hot air. During closing of the sealing jaws, surfaces on the opposed faces of the sealing jaw urge the adhesive into the space above the edge of the pouring spout to form an impermeable seal. The location of the tape on the carton blank and the apparatus for heating and sealing the carton are also described.
