Abstract: A direct injection fuel system is shown for injecting hydrogen fuel into a gas turbine combustor. The fuel injection system includes a plurality of fuel injector blocks. Each fuel injector block includes a fuel admission duct having an inlet for receiving hydrogen fuel from a fuel supply, an outlet for delivering hydrogen fuel into the combustor and a central axis extending from said inlet to said outlet. Each fuel injector block also includes an air admission duct located around the periphery of the fuel admission duct, having an inlet for receiving air from a diffuser and an outlet for delivering air into the combustor for mixing with the hydrogen fuel.

Abstract: An apparatus for imparting an organoleptic quality to a recipient product using a sensate substance obtained from a donor product, the apparatus comprising a donor product storage chamber; and a recipient product storage chamber, the apparatus being arranged to allow a fluid to circulate repeatedly between the donor product storage chamber and the recipient product storage chamber so that at least one sensate substance obtained from the donor product is conveyed from the donor product storage chamber into the recipient product storage chamber and into contact with the recipient product.

Abstract: An method for imparting an organoleptic quality to a tobacco industry product using a sensate substance obtained from a donor product, the method comprising repeatedly circulating a fluid in a closed loop through a donor product storage chamber containing a donor product and a recipient product storage chamber containing a batch of tobacco industry product so that at least one sensate substance obtained from the donor product is conveyed from the donor product storage chamber into the recipient product storage chamber and into contact with the tobacco industry product to impart an organoleptic quality thereto.

Abstract: A method and apparatus for impregnating tobacco industry products with sensate constituents of botanicals by storing the tobacco industry products and the botanicals separately and applying heat and/or pressure to the apparatus to obtain a modified taste and aroma profile, are disclosed.

Abstract: The invention is an apparatus for smoothing and leveling a hardenable paving material on an inclined surface. The apparatus can be detachably mounted onto a vehicle. The apparatus includes a base and at least one screed bar that extends outwardly from the base. The screed bar is capable of being angularly adjustable with respect to the base. The angle between the screed bar and the base can be adjusted so that the screed bar can be positioned in a substantially parallel relationship with a surface that is to be paved. The apparatus can be moved parallel to the surface to be paved so that the screed bar traverses across and levels hardenable material that has been deposited on the inclined surface. Upon completion of paving operations, the apparatus can be detached from the vehicle. In one embodiment, the apparatus can be mounted on a fork lift.
