Title: Process for producing granules
Inventor: NIJSTEN PIETER J B
IPC: C05G5/30
Filed: 1997-04-14
Abstract: A process for producing granules from a liquid composition which includes the steps of applying the liquid composition onto solid particles of the same composition circulating in the granulation zone of a granulator, thereby causing particles to grow, discharging a stream of grown particles from the granulation zone, cooling this stream in a cooler, and dividing the stream exiting the cooler, in a size-sorting apparatus, into three streams of grown particles based on size. The stream of desired-sized particles is withdrawn for future use or processing, the stream of undersized particles is returned to the granulation zone and the stream of oversized particles is sent to a size-reducing apparatus for crushing, with the resulting crushed particles recycled back to the cooler located downstream of the granulator and upstream of the size-sorting apparatus.

Patent CA-2236068-A1 (CA)
Title: Lamp stability diagnostic system
Inventor: CREIGHTON MICHAEL A
IPC: G01J1/00
Filed: 1998-04-28
Abstract: Two detectors are effectively positioned at a predetermined lateral position in a rectangular illumination field at a wafer plane. The ratio of the signals from the two detectors is calculated. This ratio is indicative of the quality of the illumination field and any lamp instability which may effect the illumination field, and therefore image quality. In a photolithographic device, a short arc mercury xenon lamp provides illumination for projecting the image of a reticle onto a photosensitive resist covered substrate or wafer. The desired illumination intensity profile is sensitive to lamp instability.          This instability may alter the desired illumination intensity profile which may adversely effect image quality, and therefore the resulting product. The ratio of the signals received from predetermined locations laterally along the illumination intensity profile improves the detection of unstable lamps.          The detectors are positioned at locations of relatively steep slope in the illumination intensity profile thereby increases sensitivity.

Abstract: Lit pneumatique (10) constitué d'un matelas à air multi-zone (20) et d'une pluralité de vannes normalement fermées (35-38) qui maintiennent les pressions dans chacune des zones (25-28) lorsque la pompe à air n'est plus actionnée. Lorsque la pompe à air est actionnée, la pression dans les zones est réglée à certaines valeurs de pression prédéterminées, idéales pour l'utilisateur. En cas d'écart par rapport à la pression idéale, un régisseur programmé (42) calcule les temps de gonflage et de dégonflage pour les zones concernées qui seraient nécessaires pour porter les zones aux pressions voulues par gonflage ou dégonflage. Pour le calcul automatique des pressions idéales, on gonfle les zones aux pressions initiales puis on les rend étanches. Ensuite, un utilisateur s'étend sur le lit et on mesure les pressions. A partir des pressions mesurées, on calcule des valeurs de pression idéales qui soutiendront l'utilisateur de façon idéale, par exemple en le maintenant dans une posture de sommeil parfaite avec une pression minimum dans les zones. Les postures autres que la posture étendue, par exemple observées lorsque l'utilisateur se relève ou s'assoit sur le bord du lit, sont détectées par l'analyse des pressions dans les zones ou d'informations provenant d'autres sources, en vue de fixer des pressions particulièrement adaptées à ces postures.
