Title: Method of forming sulphur
Inventor: WATSON RICHARD WILLIAM
IPC: B01D53/04
Filed: 1995-09-14
Abstract: In the formation of sulphur from a hydrogen sulphide containing gas stream by the Claus process, a first gas stream comprising hydrogen sulphide is fed to a burner 4 that firs into a furnace 2.  A second gas stream comprising oxygen or oxygen-enriched air is supplied from a plant 6 to the burner 4.  A third gas stream comprising at least 70% by volume of carbon dioxide is also fed to the burner 4.  The mole ratio of oxygen to nitrogen (if present) in the gas supplied to the burner 4 and hence the furnace 2 is at least 8 to 1.  Relatively high flows of hydrogen sulphide into the furnace 2 are thereby made possible.

IPC: A62B18/08
Filed: 1995-09-27
Abstract: A mask and harness system for use in providing breathing oxygen and protection from pollutants for the eyes and respiratory system as might be encountered in high altitude aviation environments. In one preferred embodiment, the mask system has a face seal, a soft flexible lens, a pneumatically-actuated harness, and a regulator with microphone to control the f low of oxygen and to facilitate communications in aircraft flight decks and other aircraft compartments. The system is designed for required five-second donning with one hand and because of the flexible lens, is capable of storage in the relatively preferred on crowded flight decks. It is connected to an oxygen source and, optionally, with aircraft communications. The regulator controls the flow rate of oxygen to the wearer based on altitude and physiological requirements. The regulator includes a valve for purging the condensation-prone moist gases from the lens area and provides positive pressure in the mask.      A second preferred embodiment molds the lens and mask seal of a single material having sufficient optical quality and flexibility to accomplish both purposes.

Inventor: REKUNYK HORACE
IPC: G01M3/38
Filed: 1995-11-29
Abstract: Method and apparatus for determining the presence and identify of predetermined gases in the atmosphere such as would be found if an oil and gas pipeline was subject to leakage.  An infrared transmitter and an infrared receiver are each mounted on an airborne platform such as a fixed or rotary wing aircraft.  As the airborne platform follows its flying program, the presence of gases is determined by the infrared transmitter and receiver and a data acquisition module mounted and operable therewith.  The geographic position of the airborne platform is determined by a global positioning system so that the location of the predetermined gases in the atmosphere is known.

Title: Twin-roll type continuous casting method and device
Inventor: MATSUMURA YOSHIKAZU
IPC: B21B1/46
Filed: 1995-04-03
Abstract: This invention provides a twin-roll continuous casting method, and an apparatus therefor, which can produce a thin sheet having excellent mechanical strength by finely and homogeneously reducing the crystal grain size, having reduced variance of materials and having excellent surface roughness devoid of skin roughness, and which can reduce the cost of equipment.      A casting C obtained by solidification by using a pair of water cooling casting rolls 2a, 2b is subjected to temperature adjustment to a temperature zone in which an austenite structure exists in its matrix. Thereafter, the casting is rolled by an in-line rolling mill 5 at a temperature ranging from 850°C to less than 1,350°C after solidification and at a reduction ratio of 5 to 50%. In this way, overall variance of elongation of the steel material is kept within 5% in terms of the standard deviation.

Patent CA-2166943-A1 (CA)
Inventor: CHAMPION MARK R
IPC: F24B1/189
Filed: 1996-01-10
Abstract: A fireplace with a cooling air passageway within the fireplace housing that maintains the forward portion of the housing top wall cool during operation.  The fireplace includes a combustion chamber, a flue, and an outer housing that encloses the combustion chamber.  Plenums formed between the walls of the outer housing and the combustion chamber walls are used to circulate room air to keep the housing cool.  Disposed within a forward portion of the upper plenum above the combustion chamber is a passageway constricting baffle.  The baffle constricts the cross-sectional area of the upper plenum through which the cooling air flows and forces the cooling air flow upwardly against the underside of the housing outer top wall, thereby cooling this portion of the housing which typically is difficult to keep cool.  The fireplace also includes a baffle which directs cooling air outlet from the upper plenum to a venturi passageway in communication with the flue.  The baffle and passageway cooperate to induce a draft of cooling air through the upper plenum when access doors to the combustion chamber are either open or closed.

Title: Fibres a deux constituants et filtres pour la fumee de tabac formes avec ces fibres
Inventor: BERGER RICHARD M
IPC: A24D3/10
Filed: 1994-11-23
Abstract: Fibres (10) à deux constituants enveloppe-partie centrale comprenant une partie centrale (14) réalisée dans une matière thermoplastique peu coûteuse, très résistante, du polypropylène de préférence, qui est entièrement recouverte d'une enveloppe (12) constituée de préférence d'acétate de cellulose plastifié, d'un copolymère d'éthylène-acétate de vinyle, d'un alcool polyvinylique ou d'un copolymère d'éthylène-alcool vinylique. On produit ces fibres et, de préférence, on les fait fondre jusqu'à un diamètre moyen inférieur ou égal à 10 microns, puis on les façonne sous forme de filtres pour la fumée de tabac. Les filtres résultants conservent les propriétés gustatives désirables et les capacités de traitement des éléments classiques de filtre à l'acétate cellulosique mais sont sensiblement moins onéreux. Etant donné que la matière de la partie centrale est non absorbante, il faut utiliser moins de plastifiant ou d'additif pour obtenir des propriétés comparables, et une bande, un stratifil (34) ou un filtre réalisé avec ces matières possède une plus longue durée de conservation. On peut former des fibres très fines ayant des sections transversales variables qui produisent une aire de surface plus importante et nécessitent moins d'air pour les procédés de fusion et de fabrication. Avec des enveloppes formées d'acool polyvinylique ou d'un copolymère d'éthylène-alcool vinylique, l'élément de filtre se décompose facilement lorsqu'il est soumis à des conditions environnementales, ne laissant comme restes qu'une multiplicité de fibres très fines, sensiblement invisibles.
