Title: Manufacturing method for manufacturing cylindrical heat exchanger manifolds
Inventor: INOUE SEIJI
IPC: F25B43/00
Filed: 1998-04-08
Abstract: Fluid is passed through the horizontal tubes of a refrigerator condenser and vertical manifolds at one or both ends which are formed from flat sheet as cylinders with end caps and tubes for connection to the horizontal passages. The condenser (1) has a multitude of horizontal passages (5), with fins (6), the ends of which (8) terminate in vertical manifolds (9), containing blocking plates (18,19) which direct the flow of refrigerant through the horizontal tubes in series. To complete the flow path an additional manifold (32) is provided to join the inlet and outlet ports (23,23). This cylindrical construction is manufactured by rolling one or two flat plates (29), joining with flanges (31) and closing with end caps (33,34). Connection tubes (35,36) are provided for joining to the heat exchanger ports (23,24).
Patent DE-19816674-A1 (DE)

Patent DE-19819445-A1 (DE)
Inventor: WASCHATZ UWE
IPC: F02D41/24
Filed: 1998-04-30
Abstract: The invention relates to a method for determining characteristic mapping data or for determining one or more parameters for one or more mathematical functions provided for controlling an internal combustion engine. The idea is that each measured value necessary for the engine control characteristic map is no longer individually detected and received by setting the corresponding influence factors on the engine which is located on the drive test stand. Rather, the remaining values are determined from a considerably smaller number of received measured values by means of numeric, especially statistical evaluation and calculation methods. As a result, the number of necessary measured values are significantly reduced thus resulting in a significant reduction of the necessary test stand measuring time. The invention also relates to an method and to an electronic engine control device for controlling an internal combustion engine. The basic idea is that each individual characteristic map value is no longer stored in the engine control device, rather merely the parameters of mathematical functions are filed. Using the parameters, said mathematical functions describe the dependency of different target variables on different influence factors. By merely filing the parameters of mathematical functions, the required storage capacity of the engine control device is significantly economized.

Title: Motor vehicle rear door stop for swivel limitation
Inventor: BLOCK JUERGEN
IPC: E05F5/06
Filed: 1998-05-30
Abstract: One of the door stops (5) is allocated a drive which responds to the door movement to move the stop (5) correspondingly.

Title: Procedure for detecting obstacles used with electric window-lifting device
Inventor: MIURA YUKIO
IPC: H02H7/085
Filed: 1998-08-27
Abstract: A procedure for detecting obstacles used in connection with an electric window-lifting device comprises: a motor (4) which is activated to open and close a window with the help of a window drive mechanism; a motor driver unit (3) which drives the motor; a pulse generator (5) which generates pulses corresponding to the revolutions of the motor; a micro-control unit (3) which takes care of the whole drive control; and an operating switch (1) which is operated by hand to induce the opening and closing of the window.  The micro-control unit is caused to determine parameter values which are representative for the load working on the window if it is either opened or closed; the micro-control unit compares the determined parameter values with a specified reference mean value; the micro-control unit is caused to establish the presence of an obstacle in the window movement if one of the determined parameter values deviates from the reference mean value by at least a specified amount; and the micro-control unit is caused to stop or reverse the rotation of the motor via the motor driver unit if an obstacle is detected. The whole movement cycle of the window is divided into several movement zones of which each zone is assigned a reference mean value which beforehand is set up as a mean value of the parameter values representing the load working on the window while the window moves across the respective zone without meeting any obstacle.

Title: Determination of water addition to sausage meat in the mincer uses computer evaluation
Inventor: ARNDT BURKHARD
IPC: A22C11/02
Filed: 1998-11-28
Abstract: The amount of water to be added will be calculated in a computer and is a factor of the force applied to an immersed sensor (the viscosity) modified by measurements of temperature, sharpness of the mincer blade and mincing time. The viscosity measurement is correlated by measurements of electrical conductivity, power absorbed by the mincer etc. Initially only meat and its components are minced. In the measurement phase the temperature is kept steady in a bowl supplied with cold water running through its double wall. The criterion for the water addition will then be the rate of change of viscosity. This water could be mixed with ice to cool the mixture. Any additional ingredients are then added to complete the process.
