Title: A catalytic system and its use
Inventor: FALK K A JERKER
IPC: B01D53/86
Filed: 1994-05-11
Granted: 1999-11-16
Abstract: A gas-cleaning catalytic unit for use in cleaning exhaust gases from small internal combustion engines, comprises an open mesh knitted or woven fabric (10) produced from heat-resistant metal wire and shaped to a pack of predetermined form having a plurality of adjacent metal fabric layers, and a casing which surrounds the pack and forms gas throughflow passages. The unit is characterized in that at least half of the layers in the metal fabric pack are comprised of metal fabric (10) which is corrugated generally continuously in at least two directions along lines (14; 15) which define an angle (.beta.) therebetween; and in that the corrugated metal fabric (10) is so arranged in the pack that the apex of said angle will point in a direction transversely to the direction of the throughflow passages.

Title: Method and equipment for producing foam bitumen
Inventor: SALMINEN NESTOR MIKAEL
IPC: B01F3/08
Filed: 1995-02-15
Granted: 2005-12-06
Abstract: The invention relates to a method and equipment for producing foam bitumen. Water is mixed to hot bitumen under a pressure which is lower than the prevailing absolute pressure, and after this the pressure is allowed to rise and the flow rate to drop. The mixing of water and bitumen occurs in a foaming reactor (17), which is connected via a pipeline (6, 8, 9, 10) to a spray bar (1), which also acts as a heat exchanger, and the changes in the flow caused by an inclination in the spray bar are compensated by means of pipes (6) and valves (7). The entire equipments is thermally insulated, and a part of it may be provided with electric heating to prevent the bitumen from solidifying. It is possible to circulate hot bitumen in the equipment by opening a valve (12), whereby the entire equipment is brought to an operating temperature.

Abstract: A system for preventing scratches, dents and die marks on sheet metal parts (10) during bending and forming operations. The system holds a supply of protective material (18), such as plastic film, canvas or sailcloth, on a roll or other convenient form and applies the protective material (18) across the die (14) and/or the punch (12) of a press brake (16) or other sheet metal bending or forming equipment. The system is configurable to cover a die (14) or punch (12) of practically any size from a few inches to several feet. The system is programmable to advance the protective material (18) a preset amount after a given number of cycles of the equipment. Different configurations of the system are described which advance the protective material (18) longitudinally along the punch (12) or die (14) or transversely across the punch (12) or die (14) of the press brake (16).

Abstract: Le moteur à explosion avec des pistons rotatifs a dans son boîtier plusieurs  cavités hébergeant chacune un piston rotatif d'une forme spéciale. Des doubles-manivelles chacu ne ayant la longueur variable relient entre eux les pistons rotatifs deux par deux. Le couple moteur cumulé de tous les pistons rotatifs est transmis à l'arbre moteur par l'intermédiaire d'une manivelle de longueur variable dont il est relié.  Chaque piston rotatif tourne librement dans sa cavité en combinant le mouvement de glissement avec le mouvement de roulement ainsi que, comme résultat, à chaque rotation complète du piston rotatif l'arbre moteur exécute trois rotations complètes en sens inverse sans l'utilisation de pignons ou d'autres mécanismes. Ce moteur a un petit gabarit par rapport à d'autres moteurs de même capacité, un petit nombre de pièces en mouvement, un bon rendement de conversion de l'énergie et un bon équilibrage. Il offre la possibilité d'avoir beaucoup de ses pièces fabriqué es en matériaux céramiques ou métal et céramiques.

Title: Method of assigning promotional messages to electronic price labels
Inventor: GOODWIN JOHN C III
IPC: G06Q30/02
Filed: 1997-05-23
Granted: 2000-06-20
Abstract: A method of displaying a promotional message by an electronic price label (EPL) which stores promotional messages and corresponding promotional indicators in a memory within the EPL.  Once the promotional messages are stored within the memory of the EPL, the promotional messages no longer need to be sent by a controlling computer each time a promotional message must be displayed by the EPL.  The controlling computer transmits a promotional indicator to the EPL.  The EPL compares the promotional indicator in the message with the promotional indicators stored within the memory.  The EPL displays a promotional message associated with one of the promotional indicators within the memory if the promotional indicator in the memory and the promotional indicator in the message are equal.

Title: Immunity against pasteurella haemolytica leukotoxin
Inventor: PRIDEAUX CHRISTOPHER THOMAS
IPC: C12N15/74
Filed: 1996-11-01
Granted: 2010-06-29
Abstract: Bovine respiratory disease (BRD) complex, shipping fever, or pneumomic pasteurellosis, is a multifactorial disease whereby a combination of viral infection, adverse environment and poor immune status may combine to predispose animals to bacterial infections. The exotoxin, or leukotoxin (Lkt), may contribute to pathogenesis by impairing the primary lung defenses and subsequent immune responses or by causing inflammations as a result of leukocyte lysis. The present invention provides a modified microorganism which produces an Lkt toxin, wherein said Lkt toxin is partially or fully inactivated. In a further embodiment of the present invention, there is provided a modified microorganism wherein an Lkt toxin operon including an Lkt structural gene and/or a post translational activator of the organism is partially or fully inactivated. The present applicants have found that a precursor of Lkt toxin has reduced toxic activity. Surprisingly, the Lkt toxin precursor is capable of inducing an immune response in an animal that offers cross protection against heterologous challenge with a microorganism which produces the Lkt toxin. A microorganism which naturally produces an Lkt toxin may be engineered to produce an inactive Lkt toxin precursor by eliminating the post-translational activator of the precursor product. Accordingly, in a preferred embodiment the microorganism is unable to produce a post-translational activator of the Lkt toxin precursor or produces an inactivated post-translational activator of the Lkt toxin precursor. The post-translational activator may be a product of the Lkt C gene.

Filed: 1997-08-12
Granted: 2006-09-05
Abstract: A needleless injector for injecting medication through the skin of a patient includes a vial which holds a volume of liquid medication. The vial includes a vial piston which moves to force the liquid medication out of the vial. A power mechanism applies force to the vial piston. The power mechanism includes a power piston which has a plurality of ratchets. A spring is positioned to apply force to the power piston. A trigger engages the ratchets on the power piston to hold the power piston in place against the force applied by the spring. The trigger selectively releases the power piston so that the power piston moves in response to the force applied by the spring. The power piston applies the force to the vial piston to cause the vial piston to force the liquid medication out of the vial. A cocking mechanism applies force to the power piston to move the power piston against the force of the spring to engage the ratchets. A travel adjustment mechanism is moveable to position the spring within the power mechanism to control the movement of the power piston and to thereby control the volume of liquid ejected from the vial.
