Inventor: COURTOIS PIERRE-JACQUES FRANCO
IPC: H04L12/56
Filed: 1988-10-06
Abstract: A controlled CSMA packet switching system of a non-persistent carrier type in which in the event of a channel being sensed busy, a new sensing point is scheduled at random in a dynamically determined time interval TS n  where     where TS u  is the scheduling time interval that maximises the expected throughput when all the stations compete for the channel access, TS 1  is the scheduling time interval that maximises the expected throughput when two stations compete for the channel access, TS n . 1  is a scheduling time interval determined in a preceding (n-1)th observation interval, G n-1  is the average offered load in the (n-1)th observation interval, and Go is a nominal average offered load. 
     I An estimation of the average offered load G n-1  is derived from an estimation of the average idle period length in the (n-1) observation interval. Three strategies for obtaining such an estimation when a station participates to at least one transmission in the observation interval are disclosed.

Abstract: Apparatus for producing an injection moulding of plastics material comprises means (18) for introducing a supply of plastics material (19) through one or more openings (43) in a mould space (13), and means (26, 34) for introducing a pressurised gas through a separate opening (44) in the mould space into the plastics material filling the mould space whereby the gas creates a gas containing cavity (25) in the plastics material and for thereafter relieving the gas pressure within the gas containing cavity before the mould is opened. The gas supply/pressure relieving means comprise at said separate opening (44) a valve port (42) opening directly into the mould space, a valve member (26) for opening and closing the valve port, and means (34) to supply pressurised gas to the mould space. The gas supply means are arranged to supply gas through the valve member (26) whilst the valve member is in a valve port closed position to create the cavity and after a moulding operation has been finished, the supply of pressurised gas can be terminated and pressurised gas in the cavity in the moulding can be vented to the atmosphere due to movement of the valve member to a valve port open position.

Abstract: In a database management system that operates according to the Structured Query Language standard, a query containing a reference to a view is processed by dynamically materializing the view through execution of the view definition. Once the view is materialized, it is treated as any other base table. To enable a query optimization plan to refer to the materialized view, a view node is introduced into the execution plan. The view node includes a subquery that results in the creation of the virtual table defined by the view. This created table is temporarily stored in a memory. The query optimizer can treat view nodes in the same manner as stored base tables, and thereby overcomes restrictions that were placed upon views by previous view decomposition approaches.

Abstract: A locking mechanism (10) for demountably securing a solenoid valve assembly (14) within a receptacle (13) in a wall (11) of a transmission housing (12) is disclosed. A retention means (35) is provided on a housing (22) of the solenoid valve assembly (14) which co-operatively interacts with various blocking faces (31,32,33) on a pillar means (25) present on the transmission housing (12) and located adjacent to the receptacle (13). A stop lug (45A), an engaging surface (43A) and a latching dog (55A) are each present on the retention means (35). First (31A), second (32A) and third (33A) blocking faces are present on the pillar means (25). Engagement of the stop lug (45A) with the first blocking face (31A) limits the angular range through which the solenoid valve assembly (14) may be rotated within the receptacle (13). When the stop lug (45A) engages the first blocking face (31A), the engaging surface (43A) is disposed in opposition to the second blocking face (32A) to preclude withdrawal of the solenoid valve assembly (14) from the receptacle (13). Engagement of the latching dog (55A) with the third blocking face (33A) normally precludes retro-rotation of the solenoid valve assembly (14) within the receptacle (13). Biasing means (50A) permits selective displacement of at least the latching dog (55A) out of engagement with the pillar means (25) to permit selective rotation, and retro-rotation, of the solenoid valve assembly (14) within the receptacle (13) to operate the locking mechanism (10).
