Patent GB-2205131-A (GB)
Title: Rotary compressor bearing arrangement
Inventor: SCHNELL DIPL-ING MANFRED
IPC: F01C21/10
Filed: 1988-05-25
Abstract: A multi-cell compressor has an housing (2) defining a borehole therein with a rotor (4) eccentrically mounted therein. Shafts (16, 17) extending from the rotor are supported in bearings (18, 19) mounted in covers (14, 15) at either end of the borehole. The designed geometry of the housing is distorted such that the rotational axes of the bearings (18, 19) are inclined to one another and define an enclosed angle therebetween which faces towards the pressure side of the compressor. The effect of this distortion is that when the compressor is at its operating temperature, differential expansion of the housing between the low and high pressure sides reduces the inclination between the bearing axes. <IMAGE>

Title: Passive accoustic range finding method
Inventor: RIVET MICHEL
IPC: G01S3/808
Filed: 1988-08-26
Abstract: An acoustic range finding system has three aligned sensors (A, B, C) and operates by correlating the signals received by these sensors and uses two additional sensors (A1, C1) the signals of which are correlated with those of a central sensor (B). The comparison between these correlations permits to eliminate the ambiguities produced when acoustic pulses in a narrow frequency range are received, which in particular permits one to determine the position of naval vessels and weapons by means of their own sonar transmissions. <IMAGE>
