Title: Reversible angle grinder with arbour lock
Inventor: TURLEY EDWARD M
IPC: B24B23/02
Filed: 1997-08-26
Abstract: An angle grinder with a reversible drive mechanism includes a hollow arbour with a bottom flange and a polygonal coupling piece which is keyed into a corresponding polygonal recess in the bottom of the arbour.

Title: Multiformat scan conversion
Inventor: DEAN JOHN E
IPC: H04N5/44
Filed: 1997-03-13
Abstract: A circuit that is easily configured to convert from a progressive scan image, e.g., at a resolution of 1280 x 720, to an interlaced image scan, e.g., at an interlaced resolution of 1920 x 1080 (1920 x 540 per field), or vice-versa.  One arrangement of the circuit employs multiplexers so that the two conversion modes share the available hardware. The circuit is only marginally more complex than a circuit that can only do the conversion in one direction. The quality of the progressive-to-interlace conversion is acceptable for high-end interlaced display systems and the quality of the interlace-to-progressive conversion is at least high enough for "mid-range" progressive display systems.

Abstract: Apparatus for detecting the level of liquid metal within a mould and the depth of mould powder on the surface of the liquid metal, includes an array of radiation detectors positioned to one side of the mould and extending to positions above and below the expected height of liquid metal and the expected depth of mould powder within the mould. A source of radiation photons is positioned on the mould side opposite to that on which the detector array is positioned, and means are provided for counting the number of incident photons received by each radiation detector or neighbouring detectors in unit time. The number of incident photons received provides a measure of the height of liquid metal and the depth of mould powder within the mould. Signals representative of the measures of liquid metal height and/or mould powder depth may be employed as control signals for controlling automatically or periodically the liquid metal height and/or mould powder depth.
Patent CA-2226495-A1 (CA)
Inventor: HALL RALPH STEPHEN
IPC: H04N5/365
Filed: 1996-07-29
Abstract: L'invention concerne un système de détection thermique (10) composé d'un ensemble de détecteurs optiques (14) et produisant une réaction aux rayonnements dépendante desdits détecteurs. En variant les caractéristiques de chaque détecteur, on produit un bruit à définition fixe qui dégrade l'image ou entraîne une autre réaction. Un miroir commutable (M1) peut, sur une position donnée (Pcal), diriger un rayonnement infrarouge d'une diode électroluminescente (20) sur l'ensemble de détecteurs (14). La diode (20) est à la fois un émetteur de lumière négatif et positif; le flux émis est un courant contrôlé de façon à être équivalent au rayonnement d'un corps noir dans une gamme de températures aussi bien inférieures que supérieures à la température ambiante. On déduit pour chaque détecteur des rapports d'étalonnage comprenant des fonctions de transfert qui établissent un rapport entre l'intensité incidente et la réponse signal. Dans une autre forme de réalisation, le miroir (M1) peut être placé dans une position d'observation (Pobs) et les rayonnements infrarouges provenant d'une scène éloignée atteignent l'ensemble de détecteurs (14). Les signaux de détection qui en résultent sont convertis en flux corrigés à l'aide de rapports d'étalonnage individuels qui ont été préalablement déduits et on obtient ainsi une image ou une réponse dont le bruit à définition fixe est réduit.

Title: A process and apparatus for obtaining paraffins or paraffin fractions
Inventor: ENGSTLER HERBERT
IPC: B01D9/00
Filed: 1998-06-30
Abstract: A process for fractional crystallisation of paraffin from mineral oil based and synthetic crude paraffin, wherein crude paraffin having a high oil content is crystallised in a crystalliser equipped with perforated metal sheets (31) extending in a zigzag in the spaces between the heat exchanger surfaces (39).  The paraffin-containing melt is only solidified to an extent such that the fractions and oils for discharge remain liquid and are run off without total solidification of the melt.  The perforated sheets (31) support the layers of crystals (43) and during sweating the paraffin is detached in strips from the heat exchanger surface (39) and is adapted to rest on the sloping perforated sheets (31).  The inclination of the perforated sheets (31) guides and moves the paraffin strips (53), so that the paraffin strips remain in contact with the heat exchanger surfaces (39) while being pressed by their own weight along the inclined surface (30) towards the heat exchanger surfaces (39).
