Title: Mecanisme de levee variable de soupapes pour moteur a combustion interne
Inventor: RILEY MICHAEL B
IPC: F02D13/02
Filed: 1995-11-20
Abstract: Il est possible de faire varier la levée de soupapes et un temps d'ouverture en déplaçant le pivot (3) d'un culbuteur ou d'un doigt suiveur (2) tout en modifiant l'ouverture de la soupape et cela pendant que le moteur fonctionne.

Title: Atm virtual path switching node
Inventor: WATANABE HIROMITSU
IPC: H04L12/70
Filed: 1997-08-18
Abstract: In an ATM virtual path switching node, upon being notified of a current virtual path by a virtual path monitoring unit, a link fault determination unit compares the number of faulty current virtual paths with a predetermined threshold value. When the number of faulty current virtual paths is equal to or larger than the threshold value, a link fault is determined, and a message communication unit transmits/receives a link fault notification signal to/from another ATM virtual path switching node. When the number of faulty current virtual paths is smaller than the threshold value, a current virtual path fault is determined, and the message communication unit transmits/receives a virtual path fault notification signal to/from another ATM virtual path switching node. The message communication unit transmits a switching control signal for designating switching from the current virtual path to a stand-by virtual path. A current virtual path information management unit manages correspondence between the current virtual path having, as one switching terminal, a self ATM virtual path switching node and a plurality of links in an ATM network.

Patent CA-2217529-A1 (CA)
Title: Processor device for terminating and creating synchronous transport signals
Inventor: HANSON GRAY D
IPC: H04Q11/04
Filed: 1996-03-19
Abstract: In the inbound direction, a tributary processor (32) includes an SPE encoder/decoder for extracting a synchronous payload envelope (SPE) from an STS-1P signal. A path terminator (62) may extract DS3 signals or a matrix payload envelope (MPE) from the STS-1P SPE. A DS1/DS3 extractor (68) generates DS1 signals from either the DS3 or MPE signals. An MPE mapper (70) creates MPE signals from the DS1 signals. A wideband stage interface (74) converts the MPE signals into matrix transport format (MTF) signals for cross-connection in a wideband center stage matrix (22). In the outbound direction, the wideband stage interface (74) receives MTF signals from the wideband center stage matrix (22) and generates MPE signals therefrom. The MPE signals are sent through the MPE mapper (70) in order to extract DS1 signals. The DS1 signals are converted to DS3 signals or another MPE mapping by the DS1/DS3 extractor (68). The path terminator receives DS3 or MPE signals for conversion into an STS-1P SPE. The SPE encoder/decoder creates the STS-1P signals from the STS-1P SPE for transmission to the appropriate interfaced subsystem or network.

Title: Multi-phase light screening agent, process for its production and for its application to the skin
Inventor: ZASTROW LEONHARD
IPC: A61K8/46
Filed: 1996-06-07
Abstract: The invention relates to a multi-phase light screening agent. The aim of the invention is to provide an improvement in the light screening properties by a special arrangement of prior art light screening agents and prevent direct contact between chemical filters and the skin. The light screening agent consists of at least two separate and essentially liquid phases, where the u/v filters are in at least two separate phases and the phases spontaneously separate after a brief and gentle mixing process while the u/v filters remain in the phase in which they where originally contained. The light screening factor is increased by a multiple by the multi-layer arrangement of the invention. It can be applied to the skin via a dispenser in which the liquid phases are separate and mixed before use.

Filed: 1998-06-09
Abstract: A credit status checking system capable of examining credit status of a customer immediately and easily, by utilizing a telephone number recorded regarding the customer through a computer system performing the examining procedure automatically is disclosed. A telephone number examining apparatus connected with ISDN as a subscriber terminal processes circuit-switched call control procedures defined in the ITU-T recommendation Q.931 as a calling terminal. A database manager searches a customer file corresponding to a customer ID input by a customer through an automated transaction machine, retrieves a telephone number contained in the customer file,and transmits the number to the telephone number examining apparatus. The telephone number examining apparatus sends a SETUP message including an unrestricted or a restricted digital information in a bearer capability information element to the network where the telephone number received from the database manager defined as a called party number. When the network does not receive the SETUP message sent and transfers a DISCONNECT message, the examining apparatus performs a clear sequence immediately and obtains a cause in an information element of the DISCONNECT message from the network. When the cause indicates one of the predetermined set of causes, e.g., "Unallocated (Unassigned) number", the examining apparatus determines the number null, and notifies of the credit information manager that the telephone number is null.

IPC: A47L9/12
Filed: 1998-08-04
Abstract: A detection means for filter means in vacuum cleaners, into which in addition to a vacuum cleaner bag at least one additional filter is able to be inserted. It comprises a sensor means responsive to the filter means inserted into said vacuum cleaner and switch means controlled by said sensor means for preventing switching of the vacuum cleaner motor if said filter means is not correctly recognized. The at least one electronic sensor means responsive to a detectable element in or on at least one additional filter by means of electromagnetic waves is connected with the switching means via an evaluating or processing means, adapted to check the correct position and design of the at least one detectable element. This renders possible not only the checking of the presence of an additional filter in the vacuum cleaner but furthermore its right placement and the right design for the respective vacuum cleaner so that impairment of and damage to the vacuum cleaner due to fitting the wrong additional filter may be avoided.
