Title: Coating wet web of paper or cardboard
Inventor: HES HARALD
IPC: D21F9/00
Filed: 1998-05-27
Abstract: The coating (4) is applied to the side of the web which is not covered by the fourdrinier.  To apply a liquid or paste coating to a running web of paper or cardboard, in a hybrid paper formation system, a wet web (3) is formed by the delivery of pulp from a stock inlet (1) to an initial fourdrinier (10). After the initial water extraction stage by the first fourdrinier, the coating (4) is applied to the side of the web which is not covered by the fourdrinier. A second fourdrinier (2) is brought to the coated side of the web, and water is extracted from the wet web between two fourdriniers. The first fourdrinier is detached from the web, for the coating medium to be applied to the other side of the web, and a further fourdrinier is brought to the second coated side for further water extraction. The coating is sprayed on to at least one side of the web, or it is applied to at least one side of the web by a film applicator or extruder. The coating is in different compositions for each side of the web. The web is supported while the coating is applied. The coating, on at least one side of the web, is an application dye with or without a filling material, or it is a pigment slurry.  An Independent claim is also included for a paper making machine, for the production of paper or cardboard, with an initial fourdrinier to take the wet pulp feed and form a wet web. A second fourdrinier is applied to the web, for the water to be extracted from it between the two fourdriniers after a coating has been applied to the exposed side of the web.  Preferred Features: After the first fourdrinier has been withdrawn, an applicator (5) coats the other side of the web, followed by a further fourdrinier brought against the second coated web surface, in a fourdrinier loop with water extraction units. At least one applicator is a spray, a film applicator or an extruder. A web support, with a suction box (7), is at least at one coating application station. Surplus coating material is removed after at least one application station. The coating is an application dye or a pigment slurry.

IPC: F16G13/16
Filed: 1998-08-28
Abstract: The invention relates to an energy guiding chain for guiding hoses, cables or the like comprising a number of chain links which are connected to one another in an articulated manner. Said links are formed by plates which are parallel to one another and by cross-elements which connect said plates. The energy guiding chain can move such that it forms an upper strand, a lower strand, and a diverting area which connects these strands, whereby the upper strand lies on top of the lower strand. The aim of the invention is to produce an energy guiding chain in which the upper strand can move using a low exertion of force and with a low level of friction while lying on the lower strand and which is constructed in the simplest possible manner. To this end, the invention provides that slide rollers (15) are provided on at least some chain links of the upper strand (28) and/or of the lower strand (29). Said slide rollers are arranged such that they can roll on the running surfaces (19) provided on the chain links of the opposite strand when the energy guiding chain (27) is moving.

Title: Thrust and propulsion production and producer works off subsonic subcritical fluid input for acceleration and heat input for ensuing deceleration and temperature increase for thrust output
Inventor: FEILER CHRISTOPH
IPC: F02K1/78
Filed: 1999-04-29
Abstract: The working fluid for subsonic or subcritical speed is first accelerated as it enters the device and is at the same time cooled down by using compressible fluids. The heat volume is then added to the fluid in the following channel of fixed or slightly diverging section (3) so the incoming fluid is slowed down in sector (3) and its pressure increases as also its temperature when using the compressible fluid. The heat is then removed by suitable exchange surface to give the thrust afforded by the heat accelerated flow of the incoming fluid now issuing over an area equal, smaller or larger than its entry surface area. The fluid can also give off heat again using suitable exchange surfaces. Incoming fluid can be gaseous or liquid e.g. water or coolants, in which case the fluid should be expanded to below saturation point where cavitation produces steam which in turn is accelerated in the converging section with expansion and cooling, until re-heated by the added heat volume. The incoming fluid is then decelerated (3) and to minimize condensation all materials should be proof against cavitation.
