Title: Traffic control in a communication system
Inventor: GINZBOORG PHILIP
IPC: H04Q3/00
Filed: 1996-11-08
Abstract: The invention relates to a method for traffic control in a communication system transferring traffic units. The method comprises the steps of (a) maintaining a continuously changing quantity determining whether an individual traffic unit can be forwarded, (b) changing the value of said quantity so that a traffic density lower than a specific predetermined value changes the value of the quantity in a first direction but no more than up to a predetermined first limit, and a traffic density higher than said predetermined value changes the value in a second direction, and (c) beginning rejection of traffic units as the value of the quantity in said second direction reaches a specific predetermined second limit. In order to save the network bandwidth the value of the quantity is also changed at rejected traffic units in said second direction, but no more than up to a specific predetermined third limit (-D, H), and when the value of the quantity is between the second and the third limit, it must again alter in said first direction up to at least said second limit before traffic units are accepted.

Inventor: TOUBORG JORN
IPC: C04B7/45
Filed: 1996-12-17
Abstract: A method for the continuous treatment of particulate material, such as cement raw meal, in an apparatus comprising a stationary reactor (6) configured as a conical spouted bed, to which the material is fed and treated in a suspended bed by means of gas which, via a centrally arranged gas inlet (21), is injected at the bottom of the reactor (6) and flows upwards through the reactor (6), and wherefrom the material is discharged via an opening (21) at the bottom of the reactor (6). The dimensions, operating parameters of the reactor (6, 21) or the volumes of the connected apparatuses (8a) are selected and regulated in such a way that during operation the bed pulsates up and down in the reactor (6) at such an amplitude that a quantity of the bed material which corresponds to the quantity of fresh feed material, when the bed is situated in its lowermost position, is brought into a zone (22) in which the gas flow velocity is lower than the minimum velocity required for suspending the bed particles, and thereby drops through the gas flow out of the reactor (6).

Title: Apparatus and method for heating foodstuffs
Inventor: WOOLLEY TOMMY R
IPC: A23L5/10
Filed: 1998-06-17
Abstract: A method for heating foodstuffs, particularly mixtures made up of small pieces of meat, comprises pressurizing the uncooked mixture to force the mixture through a flow resistance device (22) at a heating velocity. Sufficient force is applied to the uncooked mixture to produce frictional resistance heating in the uncooked mixture as the mixture travels through the flow resistance device (22). The frictional resistance heats the uncooked mixture from an initial temperature to a final temperature which may be above a cooking temperature. This final temperature converts the uncooked mixture to a desired processed mixture. The invention may also include forming the processed mixture into a desired shape and cooling the processed mixture to a setting temperature. A variable resistance device (40) may be included in the flow resistance device (22) and used to control the level of heating in the foodstuffs.

Title: Loading device for a plate press
Inventor: BOHN HANS
IPC: B27N3/22
Filed: 1997-11-11
Abstract: A loading device for a plate press, comprising two loading supports (3A, 3B) which can be displaced perpendicular to the direction of conveyance. Each loading support (3A, 3B) has at least one holding device with a conveyor belt (4) in the direction of travel. The workpiece (8) which is to be processed is placed on the upper trunk of the conveyor belt which is also used to deposit the workpiece (9) in or on the press. The conveyor belt (4) is moved in such a way that the relative speed of the upper trunk in relation to the on-lying workpiece (8) is equal to 0 for all states of movement of the assigned loading supports (3A, 3B) . As a result no relative friction occurs between the conveyor belt (4) and the on-lying workpieces (8). It is thus possible to place the workpiece (8) on the press in an extremely precise manner.

IPC: B08B3/12
Filed: 1997-04-04
Abstract: Ce procédé d'enlèvement de films, tels que des oxydes et des lubrifiants, à partir d'un substrat métallique (22), consiste à d'abord appliquer une contrainte mécanique ou thermique sur ces films de manière à rompre le film par rapport au substrat (22), puis à déplacer le substrat (22) dans une cellule d'électrolyse (30) présentant un ou plusieurs éléments d'électrode d'une polarité électrique, espacés du substrat (22) en mouvement, lequel constitue entre ces éléments un autre élément d'électrode présentant une polarité opposée, et à appliquer un signal électrique sur les électrodes, lequel circule en direction du substrat métallique (22), provoquant une gravure ou des piqûres dans la surface de celui-ci. Après le passage du substrat (22) dans la cellule d'électrolyse, on le plonge dans un fluide de cavitation, et on produit de l'énergie, soit sonique, soit ultrasonique, que l'on dirige sur le substrat (22) en mouvement, de manière à ce que des bulles de cavitation se forment sous le film, dans les zones piquées du substrat (22). Lorsque ces bulles se dilatent puis éclatent, l'onde de choc résultant de cette de cavitation et l'action du microgicleur produisent un effet de soulèvement sur le film par rapport au substrat (22).
