Abstract: The present invention relates to a photostable cosmetic or pharmaceutical light screening composition containing a dibenzoylmethane UV-A screening agent and a p-methoxycinnamate UV-B screening agent, one of said agents being incorporated into a polymer latex; and, optionally, other conventional UV-A and UV-B screening agents. Additionally, the present invention relates to a method of photostabilizing dibenzoyl-methane UV-A screening agents and p-methoxycinnamate UV-B screening agents when used together, by incorporating one of these agents into a polymer latex.

Abstract: A system and process for controlling the flow of packets carried by asynchronous time multiplex (EPACi) channels. The packets from one communication link are identified by their label and the identity of the multiplex channels which carries them. The process is comprised of allocating for each communication a predetermined clock rate and a predetermined threshold value, measuring the difference between the number of packets entering belonging to the communication and the number of pulses generated by the clock, lower bounding this difference, and, if the difference reaches a predetermined threshold, triggering a signal (DEP) which causes the detection of packets belonging to the communication in question as long as the difference is not less than the predetermined threshold.

Abstract: A system for switching information packets assigned with two levels of semantic priorities between entering time muliplex lines and outgoing time multiplex lines, the read address of a packet in a buffer memory of a switch being stored in a queueing file associated with an outgoing port intended to transmit the packet. The read address is accompanied by a bit which defines the priority level of the packet. Each queueing file is comprised of two zones in series between the input and the output. Means is included for writing in the first zone only when the second zone is full, the first zone is accessible only to high priority level packets between the reading of files. The rear addresses of low priority level packets, which were stored earlier than the read address of high priority level packet the oldest still being present in the file, is overwritten in equal number, at a maximum, to the number of read addresses stored in the first zone.

Abstract: Each entering and outgoing hybrid time multiplexed signal is made up of frames with fixed length time intervals each carrying a block of words that form either a packet or a channel, except the first time interval of each frame which contains a frame synchronization block. The multiplexed signal is applied to a packet time switch using a paragonal conversion, as in the switch described in European patent document EP No. 113 639. The switch is comprised of input and output rotation matrices, a packet buffer memory, and a channel buffer memory, a packet/channel discrimination memory, a packet label translation memory, a set of memory files for the addresses of the packets in the packet buffer memory, a read control memory for reading in the channel buffer memory, a time base and a control unit capable of changing the contents of the translation memory of the discrimination memory and of the read control memory in terms of the traffic to carry.
