Title: Motor vehicle active safety chassis
IPC: F16F9/20
Filed: 1988-05-24
Abstract: In existing safety systems for motor vehicle chassis the longitudinal force component of adhesion is controlled; excellent traction and to a certain extent also directional stability can be achieved. If the cornering forces are exceeded, cleanly rolling wheels can no longer be influenced and a self-steering process is no longer feasible. The motor vehicle active safety chassis with its electronically controlled special spring damper system is capable of controlling the lateral force component of the adhesion, that is for a constant lateral force the slip angle can be automatically adjusted on both axles for the purpose of a direction-stabilising steering process. The steering process is performed by a rapid adjustment of the transverse spring rigidity of the axles, purposely resulting in oversteering or understeering. Added to this is the fact that even cleanly rolling wheels still in the marginal range can be influenced, and this system can advantageously be combined with other systems (control of the longitudinal force component of adhesion). Fig.1 shows how the control of the transverse spring rigidity of the axles can be adjusted. Sensors(1) inform the computer (2) of the lateral force situation on the wheels, and the special spring damper elements (3) of one axle are combined with one another, as required, so that, in addition to the vehicle suspension they also...the function of a compensating spring (4) (reduction in the transverse spring rigidity) or that of a stabiliser (5)...

Title: Swash plate compressor
Inventor: MAURER THOMAS DIPL ING
IPC: F04B49/06
Filed: 1988-07-21
Abstract: For varying the delivery rate of a swash plate compressor, the differential pressure between the swash plate chamber (17) and the refrigerant suction chamber (21) and hence the piston stroke determining the delivery rate are controllable by means of two valve devices which connect the refrigerant output chamber (22), which is under a high pressure, on the one hand and the refrigerant suction chamber (21) on the other hand to the swash plate chamber (17) or isolate these from the latter. To achieve a high control quality, the valve devices are designed as 2/2-way solenoid valves (38, 39) which are activated by a controller (42). The piston stroke is fed as control variable to the controller (42). This variable is detected by means of a Hall generator (45) directly on a piston (23) or indirectly by means of a Hall generator (45') via the measurement of the pivoting angle of the swash plate (28) (Figure 1). <IMAGE>

Title: Process for producing a tubular article
Inventor: IMGRAM FRIEDRICH
IPC: B29C48/03
Filed: 1988-08-03
Abstract: The invention relates to a process for producing a tubular article and bracing with a further tubular article. In this process, a thermoplastic in the form of a powder or granules with the addition of chemical crosslinking agents and also additives and auxiliaries is subjected to a high pressure in a pressure chamber, causing the temperature of the mixture to increase to about 110@C. After this, the mixture is passed through channels of an extruding device and, while still inside the extruding device, is heated to crosslinking temperature and the extruded hollow strand is drawn continuously through a die in the same working step. As a result, a stretching of the hollow body by more than 10 % - preferably 20 % - is achieved and it is cooled in the stretched form, and consequently fixed in this form. The hollow strand thus obtained is introduced into at least one further tubular article over a length which is predetermined and to be braced, is cut to length and is heated over the length to be braced to above the crystalline melting point, whereupon the heated length of the tube attempts to revert to the form fixed in the extruder and presses against the drawn-over tubular article, and thus enters into a braced mechanical connection.

Title: Pressure-control device for regulating units, in particular in motor vehicles
Inventor: ZILLGITT ULRICH DIPL ING
IPC: G05D16/10
Filed: 1989-01-25
Abstract: Pressure-control device for controlling a control pressure for regulating units, in particular in motor vehicles. The position of a valve member (6) arranged in a housing (1) and thus the control pressure in a control-pressure chamber (12) are determined by the preloading of a control spring (16) arranged transversely to the adjusting axis (2) of the valve member (6) and acting on the valve member (6). When an adjusting element (18) is rotated, the control spring (16) is carried along by this adjusting element (18) and runs up or down with one of its supports on a first ramp (21), as a result of which it is changed in its preloading. In addition, another support of the control spring (16) runs at the adjusting element (18) on a second ramp (32) arranged between the adjusting element (18) and the housing (1) on a tightening element (26). A pronounced change in the preloading of the control spring (16) is thereby obtained at the start of the actuation of the adjusting element (18) and thus a rapid response of the valve member (6) to an actuation of the adjusting element (18) is obtained. <IMAGE>

Title: Plasticising screw and mixing device for the direct processing and colouring of mixtures of reclaimed plastic and of primary plastics materials on injection-moulding machines
Inventor: STRITZ HANNELORE
IPC: B29C48/67
Filed: 1989-03-29
Abstract: The invention relates to a plasticising screw and a mixing device for plastics processing with the plasticising unit being of normal length, having a feed zone, a compression zone and a metering zone, the mixing device comprising a shearing element and a mixing part being arranged in the metering zone. According to the invention, the metering zone is shortened by at least 2D. Arranged in this region before the screw tip is the mixing device, which comprises a plurality of shearing rings and mixing parts which alternate and can be interchanged with one another as desired. Each mixing part is made up of two mixing discs, which have axially directed clearances distributed around the circumference. Between the clearances there are webs, which are inclined in the axial direction. The mixing discs are arranged in pairs axially with respect to each other in such a way that at the circumference they form a triangular annular channel with respect to the plasticising cylinder. Radially, they are offset in such a way that a clearance lies opposite each web. The core diameters of the mixing discs and of the shearing rings correspond to the core diameter of the plasticising screw in the metering zone and the outside diameter of the mixing discs corresponds to the nominal diameter of the plasticising screw. The design and arrangement of shearing rings and mixing parts ensures for the first time the direct processing and colouring of mixtures of reclaimed plastic and of primary plastics materials on injection-moulding machines with the plasticising unit being of normal length.
