Title: Hydraulic power brake system with emergency brake cylinder
Inventor: WINNER HERMANN DIPL PHYS DR
IPC: B60T13/68
Filed: 1993-07-03
Abstract: The invention proceeds from a power brake system with a power source and at least one valve, controllable as a function of the operation of a brake pedal, for the performance of power braking using a travel simulator for extending the brake pedal travel during power braking and using an emergency brake pressure source, the latter having two displaceable pistons and two chambers adjoining them with connections. For a low-cost design affording space savings, only one of the chambers is connected to the power brake system. Instead of a usual return spring, a simulator spring (32) is incorporated into the other chamber, so that the said chamber (42) forms a simulator chamber. Consequently, a series-production brake master cylinder, for example, can be used for the low-cost integration of a single-circuit emergency brake cylinder with a travel simulator. The power brake system according to the invention with its travel simulator and the emergency brake cylinder can be used, in particular, for motor vehicles. <IMAGE>

Title: Air-fuel ratio control system for IC engine - Has sensors upstream and downstream of exhaust catalyser to evaluate air-fuel ratio with injectors controlled accordingly
Inventor: YAMASHITA YUKIHIRO
IPC: F02D41/14
Filed: 1993-07-05
Abstract: A control system for the air-fuel ratio of an IC engine has a sensor upstream (26) of the exhaust catalyser (13) to evaluate this ratio in the exhaust gases and a unit which detects the deviation of the measured ratio from a theoretical value. This deviation is used to adjust the fuel flow in the injectors (13). The deviation is estimated from the amount of certain components absorbed in the catalyser. There is another sensor (27) downstream of the catalyser (13) to measure the ratio after the gases have passed through the catalyser and a "learning" unit to derive the stoichiometric value. One stage in the process is to check whether the absorbed components in the catalyser (13) exceed thresholds for rich or lean mixtures. ADVANTAGE- Less pollution of environment by toxic exhaust emissions.

Patent DE-4324469-A1 (DE)
Title: Method and devices for the detection and interpretation of leaks
Inventor: RAMMNER BERNHARD
IPC: G01M3/24
Filed: 1993-07-18
Abstract: Supplementing other methods for determining a leak according to location and extent, the measurement of noise of a gas or liquid jet is now used here. This jet from the inside of the tube is focused in terms of direction, it moves, scans the walls and, on passing defect locations, allows distinct noise changes to be evaluated. In principle, electrically conductive and nonconductive tubes can be investigated. Operations have to be carried out inside a sealed-off tube section in the dry condition. In the case of the use, for example, of air, the jet can be provided by feeding from the outside via a (long) hose, or else at the examination location using a blower motor. If the directed jet is realised by means of a small pipe rotating transversely with respect to the axis, the entire tube cover can be included in the examination with extensive coverage by means of additional movement in the axial direction. To increase the speed of investigation, a plurality of nozzles can operate simultaneously. Furthermore, apart from determining the distance of the leak counting in the axis direction, it is further possible to determine that of the azimuth, if the position of a gravitation sensor relative to the nozzles is additionally registered.

Patent DE-4413452-A1 (DE)
Title: Antilock system for a motor vehicle
Inventor: OKAZAKI HARUKI
IPC: B60T8/172
Filed: 1994-04-18
Abstract: The antilock system improves the accuracy of the determination of a coefficient of ground friction, in that it takes account of the number of wheels locked in executing the antilock control. The antilock system determines the vehicle speed Vr from the previous vehicle speed Vr, when four wheels are locked, and from the wheel speed of the unlocked wheel when three wheels are locked. The status of the ground friction is determined on the basis of the rate of change DVr of the vehicle speed Vr. If it is determined from the ground friction status that the coefficient of ground friction  mu is low and the mark F2 is set to 1 to indicate that two wheels are locked, the value Mu for the ground friction status is set to Mu = 1. If, on the other hand, two wheels are not locked, the value Mu for the ground friction status is set to Mu = 1, provided that the previous value for the ground friction status is set to Mu = 1. If it is determined from the ground friction status that the coefficient of ground friction  mu  is high and two wheels are not locked, the value Mu for the ground friction status is then set to Mu = 3, and if two wheels are locked the value Mu for the ground friction status is set to Mu = 3, provided that the previous value for the ground friction status is set to Mu = 3.
