Title: Exhaust system for an internal combustion engine with two banks of cylinders
Inventor: PISCHKE REINER DIPL ING
IPC: F01N13/04
Filed: 1987-07-02
Abstract: In an exhaust system for an internal combustion engine 1 with two banks of cylinders and with lambda closed-control of the fuel/air ratio by means of a lambda sensor arranged in the exhaust gas, the exhaust gases from one bank of cylinders and those from the second bank of cylinders are passed into a mixing chamber 12' through exhaust manifolds 10' and 11' respectively, from which there emanate two exhaust pipes, in each of which is arranged an exhaust catalyst. In order to achieve intensive mixing of the two exhaust flows in the mixing chamber 12', the manifolds 10' and 11' are inserted into the mixing chamber 12' and their outlets 20, 21 are offset in such a way that the exhaust-gas flows emerging from them partially intersect and partially flow past one another. <IMAGE>

Title: Bottle with separable bottom as a plastic container for all consistent emulsions (pastes, creams, shampoos, jellies, etc.)
Inventor: FLAIG GERHARD
IPC: B65D17/40
Filed: 1987-08-22
Abstract: The invention relates solely to plastic containers in a bottle shape which are used for accommodating consistent emulsions. This type of bottle is characterised in that there is formed, in the lower half, a tear-off strip which runs all around and is provided with a small tab. By means of this tear-off strip (see Figure 3), a lower part (bottom) of the plastic bottle can be separated without difficulty. This is carried out when the contents of conventional plastic bottles cannot be used up completely through the usually small openings on the lid or closure. In conventional plastic bottles, it is therefore unavoidable to leave a certain residue of the contents unused. The intention of this invention is to be able to use the contents of the bottle completely. According to the invention, this object is achieved in that the bottom of this plastic bottle is separated in the lower part by means of the tear-off strip described, provided with a small tab. The residual supply is thus made easily accessible to the user. The result is that the contents of the bottle can be used up completely. <IMAGE>

Title: Device for the suppression of longitudinal vibrations on a vehicle with shift transmission
Inventor: KADEN JOACHIM
IPC: B60K23/02
Filed: 1987-09-25
Abstract: In a vehicle with shift transmission which has a clutch hydraulically operable by means of a master cylinder and a slave cylinder, it is proposed, in order to prevent the excitation of disturbing longitudinal vibrations of the vehicle in the event of abrupt torque variations of the engine of the motor vehicle, that the clutch at times be released when the rate at which the driver operates the accelerator pedal is too great. This operating rate is monitored by means of an accelerator pedal position sensor. If a threshold value for the rate of operation is exceeded, pressure, controlled by a valve, is introduced into the output pressure chamber of the master cylinder and/or into the drive pressure chamber of the slave cylinder, the piston of which acts on the clutch release fork. As a result, a slip is obtained in the drive train of the vehicle, which prevents the excitation of vibrations. This slip is kept within a limited range of values from 80 min<-1> to 240 min<-1>. After a period Tr the clutch is firmly engaged.

Title: Magnetoresistive element made from ferromagnetic material, and method for producing it
Inventor: SHIBASAKI ICHIRO
IPC: H01L43/12
Filed: 1988-01-07
Abstract: Magnetoresistive elements made from ferromagnetic material of high sensitivity and outstanding reliability are described. The sensitivity of these elements can be improved by maintaining the film resistance of the supply conductor parts (102) at a low value. It is possible to prevent the occurrence of an offset voltage due to an alignment discrepancy by arranging that the width of the supply conductor parts (102, 120) is larger at the points of connection with magnetically sensitive parts (101, 110) than the width of the magnetically sensitive parts, and that the points of connection are arranged in such a way that they are in a geometrically symmetrical relationship. This configuration permits the magnetically sensitive parts (101) to be connected to the supply conductor parts (102) in a self-aligning way. <IMAGE>

Patent DE-3812471-A1 (DE)
Title: Foundry core for a crankcase
Inventor: SIXT KARL
IPC: F02F7/00
Filed: 1988-04-14
Abstract: The chaplets of a water-jacketed core for a crankcase of an internal combustion engine simultaneously form the water transfer means between the water jacket and the cylinder head. It is thus possible to dispense with the core holes hitherto required in the outer wall of the crankcase. The water-jacketed core is divided in the plane of symmetry, which extends in the longitudinal direction in the crankcase. Significant drafts (mould tapers) of the water-jacketed core with their decisive effect on the shape of the crankcase, are thus not required. It is thus possible for the dividing walls of the crankcase which bound the water jacket to be designed with a constant thickness.

Title: Process and arrangement for flow metering by means of ultrasonic waves
Inventor: STEINACHER MICHAEL
IPC: G01F1/66
Filed: 1988-12-23
Abstract: For flow metering by means of ultrasonic waves, two ultrasonic transducers are arranged at a distance from each other on a measuring tube, one of which operates as a transmitting transducer and the other as a receiving transducer. To determine the flow, the phase shift between the transmitted signal and the received signal is measured in a digital manner by counting, in the measuring time intervals corresponding to the phase shift, the respective periods of a signal at a counting frequency which is significantly higher than the frequency of the transmitted signal. The starting phase, which is exhibited by the counting frequency signal at the beginning of each counting process with respect to the measuring time interval, is changed from measuring time interval to measuring time interval in one measuring cycle comprising a plurality of successive measuring time intervals, and the count values obtained in the course of the measuring cycle are evaluated for forming a measured value with an increased measuring resolution.
