Patent EP-0682436-A2 (EP)
Inventor: BOWEN DONALD JOHN
IPC: H04R1/40
Filed: 1995-04-26
Abstract: A voice-actuated switching system connects one or more microphones to an audio line in accordance with the output signal levels from each of the microphones. To reduce the effects of degradation of speech signals due to reverberation and noise pickup, the switching system uses directional microphones housed in a circular enclosure and arranged in a conference array configuration with response patterns aimed outwardly from the center of the enclosure. The switching system also uses a voting algorithm to select for activation the appropriate microphones indicative of the position of one or more people speaking and a variable weighting factor for gradually turning on or off the signal from each activated microphone that is coupled to the audio line. Typically one microphone will be selected to monitor a person speaking. Since its response pattern is normally pointed in the direction of the person speaking, it is less sensitive to speaker echo due to reverberation. If two people are simultaneously speaking on opposite sides of the array of directional microphones, however, two generally opposed microphones are selected, and the amount of reverberation increases only slightly over the amount of reverberation that would be present if just a single microphone were employed.

Abstract: An improved method for testing a large memory array of a digital computer system during system initialization or reset. First, the memory test method checks the whole memory array for addressing faults, and then a first portion of the memory array for both address line and data failures. While operational firmware is loaded into and begins to execute from the tested first portion, the remaining address locations of the array are tested in a background task. Beginning at the last address of the first portion, sequential portions of memory array are tested and released to the functional code as they have been tested.

Title: Catalyst regeneration
Inventor: VERCAUTEREN RONNY LEONTINA MAR
IPC: B01J38/48
Filed: 1995-10-30
Abstract: The present invention relates to the regeneration of a supported molybdenum 
catalyst which has been used for the epimerisation of a saccharide. The 
preferred epimerisation is the conversion of glucose to mannose. The catalyst is 
regenerated by using an oxidising agent such as a peroxide. The regeneration 
step can be repeated several times. A further extension of the useful lifetime of 
the catalyst is obtained by including one or more washing steps.

Abstract: The stacking board is designed as a stackable pallet (1) which exhibits on its underside, on opposite side borders (1a, 1b), in each case two hollow feet (2) and two hollow latching protuberances (4,5) with a smaller engagement depth than that of the feet. The feet on each longitudinal border of the pallet are located opposite the hollow latching protuberances on the other longitudinal border. When a number of pallets are stacked upon one another, depending on the orientation of the pallets, either a tightly packed storage stack is produced where the feet of the top pallet are sunk into the hollow feet of the lower pallet, or a working, spaced apart stack is produced where the feet of one pallet engage into the hollow latching protuberances of the pallet below.

Abstract: The system to be patented is a device suitable to eject the emergency parachute (m) of paragliders, hang-gliders, and other types of aerodyne and aerostat towards a predetermined direction, at such a speed as to ensure its quick opening. 
     It consists of a plate which is to be located between parachute and pilot (or aircraft). By opening a quick discharge throttle (l) the gas compresed into a small bottle (a) swells immediately a flexible component (f) and gives a powerful thrust to the parachute (m), which stretches out into the air. The parachute bag (n) is released thanks to the separation of fixed and movable components of the system. 
     Movable parts come to a halt when held up by the maximum lengthening of the flexible component (f). The device is meant to reduce weights and dimensions as much as possible, while providing high power. Manual ejection of the emergency parachute is a possible alternative.

Abstract: A scroll type fluid displacement apparatus includes a first and a second scroll, each having an end plate and a spiral wrap extending from one side of the end plate. The spiral wraps interfit at an angular and radial offset to make a plurality of line contacts which define a pair of fluid pockets. A driving mechanism is operatively connected to the first scroll to orbit the first scroll relative to the second scroll while preventing rotation of second scroll to thereby change the volume of fluid pockets. Sealing elements are disposed in the axial end of the spiral wraps for sealing a central portion of fluid pocket defined by the spiral wraps. Thus, the axial sealing of fluid pocket formed between the orbiting and fixed scroll is more secured in all process from the suction to the discharge stage. Further, the volumetric efficiency of the compressor increases.
