Title: Seals for fuel injection pumps for internal combustion engines
Inventor: BRUNEL ANDRE
IPC: F16J15/00
Filed: 1988-12-14
Abstract: In a fuel injection pump which is to be sealed off from the outside by a shaft seal, there is a risk that the seal will be subjected to heavy stress by leakage flows because of the high internal pressure in the chamber, and will hence wear rapidly. The leakage flow is reduced by an element 6 which surrounds the drive shaft 2 in the manner of a sliding bearing and is both axially and radially displaceable against surrounding housing parts, as well as by a relief line 12, which connects the relief chamber 8 to the suction side 13 of the feed pump 4 and draws off the leakage flow by the vacuum, prevailing at this location. This solution is particularly suitable for designs in which, for reasons of cost, a roller bearing 3 is provided in place of a sliding bearing for guiding the drive shaft 2. <IMAGE>

Title: Signal transit time measurement through a fluid
Inventor: GILL MICHAEL JOHN
IPC: G01F1/66
Filed: 1989-10-31
Abstract: A measurement system for measuring the time for a signal to pass between two transducers TDR1,2 to allow fluid speed or flow to be determined in a gas meter for example. Each transducer can transmit or receive signals. The system is controlled by a microcontroller 31 and a signal with a phase change acts as a marker which is transmitted from transmitter 21 via matching stage 22,23 from one transducer and is received by the other. On receipt via the matching stage and amplifier 24 it is sampled by capacitor array 25 and detected in detector 29. Amplitude information from array 25 is made available to the microcontroller to compute time of signal travel and hence flow rates.

Title: Plural rotor/stator arrangement driving double fans
Inventor: REINHARDT WILHELM
IPC: H02K7/14
Filed: 1992-05-07
Abstract: The invention relates to a drive unit for a double fan consisting of two external rotor motors (1, 2) arranged alongside each other on a common motor shaft (3), wherein the external rotor motors (1, 2) are arranged with respect to each other in such a way that the poles of the stators (12) of the two motors (1, 2) and the poles of the rotors (7) of the two motors lie in mirror image symmetry with respect to each other with reference to a dividing plane X-X running between the two external rotor motors (1, 2) at right angles to the motor shaft (3). The motors run in synchronism and have a smaller external diameter than would be the case for a single motor so that air intake is improved and the shorter winding lengths make the motors easier to wind. Heat extraction from the bearings is facilitated so that the bearings run cooler with longer service life. <IMAGE>
