Abstract: Computer-implemented methods and computer systems for an electronic transaction platform that enables the buying and/or selling of securities by users. The methods and systems relate to controlling communication of information during an electronic communication session for trading a financial instrument between an initiating user and one or more invitee users with the assistance of a dealer user or other intermediate entity. When a dealer with whom the initiating user has a relationship does not have a relationship with invitee users that may desire to trade for the security, a second dealer can be included in the electronic communication session, where the second dealer has a relationship with such invitee users. Various levels of participation are available for each user and correspond to what information each user is provided during the electronic communication session.

Abstract: In this invention, air leakage controls, method of controlling air leakage, and system for controlling air leakage in an industrial tunnel oven for use in an industrial tunnel oven and process for heating products conveyed along the tunnel oven.

Abstract: Before being processed in a pneumatic separator or classifier (13), a stream of cut tobacco, travelling to the separator on a conveyor (12), is passed through an opener (11) to open up tangled masses of tobacco that cannot be handled by the separator. The opener comprises carded rollers (1, 2, 3 and 4) having sequentially increasing peripheral velocities. Rollers (1,2 and 4) rotate in the same direction as each other, away from the conveyor, so that tobacco passes over the top of each roller, whereas roller (3) rotates in the opposite direction. The carding pins on rollers (1, 2 and 4) are inclined 5.degree. to the normal, in the direction of rotation. The pins on roller (3) are inclined at 30.degree., also in the direction of rotation, so as to trap the tobacco as it is moved around underside of the roller.

Abstract: An apparatus for providing a water vapor-air mixture for treating a hygroscopic material having a mixing chamber, supply for providing air to the mixing chamber at a temperature in the range of 0.degree. C. to 80.degree. C. and at a pressure in the range of 1 to 3 bar, supply for providing steam to the mixing chamber at a temperature in the range of 100.degree. C. to 25.degree. C. and at a pressure in the range of 1 to 10 bar, the mixing chamber having an outlet in connection with a treatment chamber to provide the treatment chamber with a water vapor-air mixture at a temperature below 200.degree. C. and at a pressure in the range of 1 to 5 bar.
