Title: Method for the formation of insulating bodies for exhaust silencers and the product obtained by the method
Inventor: PELLIZZARI ALDO
IPC: F01N13/18
Filed: 1985-10-15
Abstract: An insulating body for vehicle exhaust silencers comprises a winding of a mineral wool layer and a braiding fixed inside the winding. According to the new method the body is formed in that a band of a resinous mineral wool layer is first wound around a tube (or a core), the inside diameter of which is essentially equal to the outside diameter of the braiding; this is followed by heating in order to bond the mineral wool layer. The tube is then withdrawn and a prepared braiding, which for support is provided with a metal spiral, is introduced into the receiver thus obtained. Finally the braiding is fixed to the mineral wool winding by means of adhesive. In this way an insulating body is obtained with braiding over the entire passage length.

Title: Oscillating pump having a sensor cell with oscillating magnets which conform with pulses
Inventor: HOELTER HEINZ DIPL ING
IPC: G01N27/12
Filed: 1986-05-13
Abstract: The subject matter of the main application P 3604340.0 is a sensor which has forced ventilation, the air masses in front of the sensor surface being caused to oscillate by an oscillating pump. These oscillating pumps are subject to natural wear. In order to minimise this wear, the invention proposes that the oscillating pump be driven via a pulse-excited magnet, the DC armature being supported in a floating manner between tension springs and compression springs. Very economical DC plunger-type magnet armatures can thus be used, the oscillating movement taking place without any mechanically abutting boundary as a result of the floating, overhung suspension, and thus making it possible to operate with little wear.

Title: Fuel injection system
Inventor: KROEMER GUENTER DIPL ING
IPC: F02M69/22
Filed: 1986-05-23
Abstract: A fuel injection system with continuous intake pipe injection has an air flow measuring element 4 arranged in the intake pipe 1, which element acts on the control piston 7 of a fuel metering valve 6 in order to meter a quantity of fuel proportional to the air quantity flowing through. The metering element 4 is swivelled against a return force, which is generated by the fuel pressure in the chamber 24 acting on the control piston 7. An electric pump 16, which by way of an accumulator 35 delivers fuel into a fuel line 18, from which a control pressure line 21, connected to the chamber 24, branches off by way of a throttle 22, serves for the fuel supply. By varying the pressure in the control pressure line 21 the return force and hence the fuel-air ratio can be adjusted as a function of operating parameters, for example by means of a warm-air regulator 26 between the control pressure line 21 and a return line 28 leading to the fuel tank 17, in which latter line a pressure maintaining valve 27, acted upon by the fuel pressure, is arranged. In order to ensure restarting, especially when the internal combustion engine is still warm, an additional accumulator 36 is provided between the control pressure line 21 and the return line 28, which accumulator is briefly filled with fuel after starting, as a result of which the pressure in the control pressure line 21 and hence in the chamber 24 briefly falls, which ... a stronger deflection of the air flow measuring element 4 and a ...

Title: Method and circuit arrangement for converting analog signals into binary signals
Inventor: STRAND STEINAR
IPC: G11B20/10
Filed: 1987-05-27
Abstract: In a conversion of analog signals (A, B) into binary signals (D), additional zero crossings of the differentiated analog signals (C) can occur in a differentiation of the analog signals (A, B) which produce unwanted additional binary signals (D). To avoid the additional zero crossings and to increase the noise immunity, the analog signals (A, B) are integrated and inverted and added to the differentiated analog signals (C). Whenever the analog signals conditioned in this manner have zero crossings, the binary signals (D) are generated from them. The method and the circuit arrangement are particularly advantageous if read signals are provided as analog signals which are generated by a magnetic read head when reading data recorded on a magnetic recording carrier. <IMAGE>
Patent DE-3726798-A1 (DE)
Title: Brake system with slip control
Inventor: REINARTZ HANS-DIETER
IPC: B60T8/40
Filed: 1987-08-12
Abstract: A hydraulic brake system is demonstrated, in which, at the start of slip control, the pumps (18) feed pressure medium into the master cylinder chambers (6, 7). The pumping pressure of the pump (18) is determined by pressure limiting valves (20, 21), which are acted upon by a control force as a function of the displacement travel of the float piston (5). The spring system (22) is designed so that, as from a certain displacement travel, the switch point of the pressure limiting valves is greater than the master cylinder pressure attained at the commencement of brake slip control. In this way, it is ensured that, in the case of small displacement travels, the pistons (4, 5) remain approximately in their position at the onset of slip control, whereas in the case of large displacement travels, the pistons (5, 6), at the onset of slip control, are returned into a position which does not correspond to the basic position but which guarantees an adequate reserve volume for emergency braking. <IMAGE>
