Title: Compressed-air system with detachable compressor clutch for vehicle compressed air braking system
Inventor: KNAUST HOLGER
IPC: F04B49/02
Filed: 1997-04-08
Abstract: The system has a compressor which is driven via a detachable clutch and charges an air-bottle. The clutch is pneumatically operated by a governor, being detached on reaching working pressure in the bottle. The governor housing has an inlet union (2) supplied with the bottle pressure, also an outlet union (3) with venting equipment. The venting equipment for the governor outlet pressure has a retaining valve (35a) preventing discharge of the outlet pressure to atmosphere when a pressure slightly above atmospheric is reached. It can be arranged to stop discharge when excess pressure is roughly 1 bar. When outlet union pressure falls, the retaining valve can be arranged to supply compressed-air from the bottle until the desired pressure is reached.

Patent DE-19730502-A1 (DE)
Inventor: ROHDE WOLFGANG
IPC: C12N15/80
Filed: 1997-07-16
Abstract: The invention relates to the characterization and use of powerful viral promoters for expressing genes in bacteria and fungi, especially yeasts. The invention is based on a surprising discovery, namely that CFDV-DNA (DNA of the coconut foliar decay virus) and fragments of CFDV-DNA contain a region active as promoter even in bacteria and fungi, especially yeasts, although they originate from a virus which infects monocotyledonous plants. The activity of these promoters in E. coli is markedly greater than that of the CaMV 35S promoter which is also active in bacteria.

Title: Continuous production of flat foamed panels with fewer irregularities
IPC: B29C44/46
Filed: 1997-09-20
Abstract: In a continuous process for manufacturing flat foamed panels, especially panels with facing layers, a liquid reactive mixture is dispensed continuously onto a conveyor (3) in a transverse direction and then air jets directed over the entire width of the foaming strip (8) deform the foaming surface of the latter.  A recovery of the foam then occurs and inhomogeneity caused by air voids is eliminated giving a smooth flat surface before the foaming strip(8) enters a double belt press(10) from which the final product is removed. Plant for the process comprises a dispenser (1) for the reactive mixture (2), a conveyor (3) with a feed zone (4) for the mixture (2), a blowing device (11) for directing air jets onto the reacting material strip (8) on the conveyor (3) and a double belt press (10) for pressing the foamed panel.  The dispenser (1) has nozzles arranged behind each other in the conveying direction (f) and moves across the conveyer (3) when dispensing the mixture (2).  The blowing device (11) has air nozzles arranged transverse to the conveying direction so that air jets can impinge on the entire width of the foaming strip (8).

Filed: 1998-06-12
Abstract: The fiber feed system to a carding machine, to form a flocked fiber web, has a rotary bearing mounting for each feed trough (7), at common mountings (25) across the width of the machine. The feed troughs (7) and the feed rollers (6) are mounted independently of each other, but in relation to each other. The common trough mounting (25) is a longitudinal beam, with its ends fitted to the side walls of the machine frame. The mountings at the beam can be adjusted for position. The mounting beam (25) is a square or rectangular hollow steel profile, resistant to bending with the moments of inertia at the carriers generally equal in the vertical direction and with similar resistance moments. The carrier (25) is outside the reserve and filling shafts (2,9). Each feed trough (7) is under tension from a spring or a pneumatic unit, all supported at the carrier (25) by holders at one end of the springs, and the feed troughs (7) at the other end of the springs. The feed troughs (7) are on rotating mountings at one side, close to the carrier (25).  Each trough is placed at a holder for the spring on the carrier (25), near the corners of the carrier (25). The press forces are generally the same between the feed troughs (7) and the feed roller (6). At least one limit stop defines the rotating path of the trough (7), mounted opposite the carrier (25). The feed troughs (7) have a wear-resistant surface where in contact with the fiber materials, with a plate or surface plating. The plate is bonded to the trough by an adhesive. The fiber materials pass from the feed station (6,7) into a filling shaft (9) for the carding machine, where the material is pulled into the filling shaft (9) from the reserve shaft (2) through an opening roller (8) which can act as the breast roller (15) of the carding machine followed by a further breast roller. The feed roller (6), reserve and filling shafts (2,9) are mounted to the machine frame. Each feed trough (7) has a monitor to register the fiber density, linked to a control to adjust the distribution of the fiber material across the shaft (2,9) width of 2.5 m and more.
