Patent DE-3715442-A1 (DE)
Title: Twin-chamber container
Inventor: HAMMER HELMUT
IPC: B65D81/32
Filed: 1987-05-08
Abstract: Twin-chamber containers for foods, in particular yoghourt and a cereal preparation, are known, in which the cereal preparation located in a small chamber can be tipped, by pivoting the small chamber about a web, into a large chamber in which the yoghourt is situated. It is disadvantageous in the known container that, on the one hand, a great effort is required for pivoting the small chamber and that, on the other hand, the web breaks apart. In order to facilitate the handling and, in particular, the tipping of the contents of the small chamber (3) into the large chamber (2) of the twin-chamber container (1), the line of weakness (6) formed in the web (5) and acting as a hinge is designed to have essentially the same length as the side (7) of the small chamber (3). The twin-chamber container is used for yoghourts and other dairy foods to which a cereal mixture or the like is to be added prior to consumption. <IMAGE>

Patent DE-3731073-A1 (DE)
Title: Linear drive
Inventor: BRAUSFELD WALTER DIPL ING
IPC: F15B15/02
Filed: 1987-09-16
Abstract: In a known linear drive, the pulleys of a looping transmission connected between a drive device and a driver are provided on a rail which runs parallel to the longitudinal axis of the drive device and is in turn fastened to an extension arm arranged on the drive device in such a way as to run transversely to the longitudinal axis of the latter. In such an arrangement of the looping transmission it can be of disadvantage that transverse forces are exerted on the drive part of the drive device. The invention therefore proposes a solution in which forces occur which act on the drive part merely in the direction of the longitudinal axis of the drive part. The invention proposes to arrange the pulleys (28, 30) on the drive part in the area of the line of movement of the drive part (15, 14, 27) and to provide one additional pulley (20, 2) each in the area of the end faces of the drive device facing one another, over which additional pulley (20, 2) the tension element (8) of the looping transmission is run. <IMAGE>

Title: Method for controlling the composition of the exhaust gas of an internal combustion engine
Inventor: HENNING MANFRED
IPC: F02D41/14
Filed: 1988-01-27
Abstract: Known control methods and devices have the disadvantage that due to the specific characteristics of capacitors the integrator gradients of a control unit having at least integral control action are fixed. Continual optimising of the integrator gradient is thereby impossible. The invention therefore proposes that the gradient value for the integral component be set to a constant value, that the integral component be stopped at a predetermined frequency and restarted, that the duty factor between control time and stop time be fixed as a function of characteristic operating variables drawn from performance characteristic memories. The invention has applications in an internal combustion engine with fuel metering system and an oxygen probe ( lambda -probe) arranged in an exhaust duct.

Patent DE-3814580-A1 (DE)
Inventor: SCHULZE ECKEHART
IPC: B21D28/24
Filed: 1988-04-29
Abstract: In a hydraulic control device for the drive control of a double-acting hydraulic cylinder with a relatively large driving face and a relatively small counterface on its driving piston, a direction- and- motion-control valve is provided in the form of a follow-up control valve which operates with electrically controllable desired position value stipulation and mechanical actual position value feedback. The pressure supply unit provides two supply pressures PN and PH of different magnitude. A pressure-controlled pressure changeover valve is provided which switches over to high supply pressure as required if the load increases. Also provided is a face changeover valve, likewise pressure-controlled, which, after the pressure changeover valve has switched over to higher supply pressure, switches over from differential operation of the hydraulic cylinder to pressurisation on one side of its piston, on the larger piston face of the latter, or, if the requirement for propulsive force has decreased again, after the pressure changeover valve has for this reason switched back to lower supply pressure, for its part switches back to differential operation of the hydraulic cylinder.
