Patent DE-19651559-A1 (DE)
Title: Adaptive control for automobile IC engine relative to emissions control system output variations
Inventor: TROMBLEY DOUGLAS EDWARD
IPC: F01N11/00
Filed: 1996-12-11
Abstract: The engine management system monitors the performance of the engine against set parameters and measures the differences between the expected settings and the actual measured settings; this provides a measure of the state of the catalytic converter, when compared with reference values. The engine management control can then be adjusted to take account of the deterioration of the catalytic converter. Engine parameters which are monitored include the ignition timing setting, the engine speed at set throttle settings and the heating system for the catalytic converter ( for cold starting). The control system can estimate the temperature of the catalytic converter and adjust same to maintain the effectiveness of the converter.
Patent DE-19706374-A1 (DE)
Title: Agglomeration of scrap plastics, especially wet film off cuts
Inventor: PALLMANN WILHELM
IPC: B29B17/00
Filed: 1997-02-19
Abstract: In a process for continuous processing of preshredded, wet thermoplastic scrap, especially film off-cuts, to form a homogenous agglomerate the plastic is  compressed to remove most water and in a subsequent decompression stage heat from the following plasticisation and pressurisation at the agglomerator (1) evaporates the remaining moisture. The steam created flows back through the loosened-up off-cuts in front of the agglomerator (1) and is drawn off. Process equipment comprises a feed unit (2) with a diffusion screw (26) at the free end entering a disc-shaped annular chamber in which the film offcuts are plasticised by frictional heat and agglomerated under pressure. The diffusion screw (26) has an outer cover (36) with perforations through which the steam escapes. Steam is prevented from returning to the conveyer screw part of the feed unit (2) by a vapour barrier between the diffusion screw (26) and the input side (25) of the feed unit. Preferably the feed unit (2) comprises a compressing screw (25) prior to the diffusion screw (26). The diffusion screw (26) forms an enlarging cone in the conveying direction, has a screw spiral (38) with perforations and has a screw pitch increasing in the conveying direction. A restrictor ring (35) between the input side (25) of the feed unit (2) and the diffusion screw (26) creates a restriction in the compressed material to form a vapour barrier. Conveying elements, e.g. paddles or notches, of the diffusion screw (26) effect a loosening-up of the previously compressed plastic material behind the barrier ring (35). Perforations in the diffusion screw cover (36) enlarge in the outward direction. The diffusion screw (26) is surrounded by a hermetically sealed housing (42) with cooling water injection nozzles (43) to condense the steam and has an outlet (44) connected to a suction pump (45). A common drive system (4) powers both the agglomerator (1) and the feed unit (2).
Patent DE-19708680-A1 (DE)
Title: Ingredient-moisture-measuring equipment for building-material mixture
Inventor: BITTMANN PETER
IPC: G01N33/38
Filed: 1997-02-21
Abstract: The inherent moisture of material flowing out of a storage hopper is measured using an inclined guide plate, incorporated in which is incorporated measuring equipment calibrated to suit the material. The plate(5) is equipped to influence the material flow, and can be immediately adjacent, to the hopper(2). At the discharge end it can have a ram-operated baffle plate moved above the guide-plate, causing the material to accumulate along the latter. On completion of measurement this is lowered, allowing the accumulated material to flow away. Alternatively there can be a transverse barrier on the plate forming an obstruction.

Title: Drilling fixture for plastics pipes under medium pressure
Inventor: SCHAFSTEIN JUERGEN
IPC: F16L47/34
Filed: 1997-03-26
Abstract: A branch connection (12) extends from the drilling connection (11) and may take away material after drilling. A cutting bush (20) in the drilling connection is capable of both rotary and axial movement. The cutting bush produces a valve sealing point with the pipe connection when it is in its pushed-out position, thereby cutting off a medium flow to the branch connection. For formation of the valve sealing point, the cutting bush supports a valve sealing ring which is movable in conjunction with the rotary and axial movement. The drill connection in an end zone (34) of the casing (30) has a hollow cylindrical end section comprising an area (34) of the casing (30), over which a plastics skin is drawn.

Title: Data transmission monitoring method for car ECU and injector pump control unit
Inventor: FISCHER WERNER
IPC: F02D41/22
Filed: 1997-07-05
Abstract: The monitoring method involves sending data from one unit to the second unit, and the second unit sending at least part of the data back to the first unit, which then compares the two. It recognises an error if the data differ, and in the second unit, the data are coded before transmission. The method is for an engine control apparatus for the first control unit that processes specific engine data, and a pump control apparatus for the second control unit, which processes specific pump data. For the data, the procedure concerns signals that determine the fuel injection into an IC engine.

Patent DE-19804184-A1 (DE)
Inventor: KRAMER CARL PROF DR ING
IPC: C21D9/63
Filed: 1998-02-03
Abstract: The invention relates to a device for guiding bands in a suspended manner and for stabilizing bands, preferably wide metal bands, for the purpose of heat treating the same. In the device, the band is blown on both sides with the aid of suspended nozzle sections, and two respective radial ventilators with 360 DEG  spiral casings are arranged on the side walls of the device in the vicinity of both sides of the band. The intake openings of the radial ventilators point toward the middle of the device. The axes of the radial ventilators are vertical in relation to the side walls, and the radial ventilators are arranged in such a way that they deliver air into air delivery channels (6) from the length of at least one hydraulic diameter in a manner parallel to the longitudinal direction of the device, that is, in a direction of movement of the band. The air delivery channels (6) are adjacent to the upper casing (8) or the lower casing of the device via a side wall. Elbows are respectively connected to the air delivery channels (6). The volume stream delivered from said elbows by the radial ventilator enters a collecting receptacle which extends as at least one piece over the entire length of the device and which is provided with the nozzle section on the side facing the band, said nozzle field being approximately equal in width to that of the collecting receptacle. The gas stream blown on the band predominantly flows away and up to the longitudinal sides of the device and enters from the sides of the device into the suction area between the radial ventilators above and below the band (1).

The valves (26) and respective wheels are arranged in groups of several wheels each, with the switching valves (26) allocated to the pressure control valves or valve groups, each of which contains its allotted fluid pressure control valves (21). Current supply relays allotted to control valves or their groups (21) switch the valves and switching valves (26) parallel to a current supply source. Fault sensors (50) detect faults throughout and a fault controller (51) on detecting valve or group faults so controls the respective relay that only one control valve in the faulty group etc connects the corresponding wheel to the main cylinder.
