Title: Dual signal receiving system
IPC: G01S3/48
Filed: 1966-05-20
Abstract: 1,121,289. Radio direction finding. COMPAGNIE FRANCAISE THOMAS-HOUSTONHOTCHKISS BRANDT. 20 May, 1966 [21 May, 1965], No. 22644/66. Heading H4D. A radio direction finding interferometer system is adapted to determine the direction α, Fig. 1, of a source S radiating signals which are received at antennµ 1 and 2 with a frequency nominally constant at f but actually subject to an erratic frequency shift (e.g. doppler shift, or transmitter drift). A phase difference / # = /# 1  / # 2  exists between these two received signals proportional to α, and the system described eliminates the frequency shift before measuring /#. A differential heterodyne stage 8 produces a first signal of frequency f-f 1  and zero, / # phase, and a second signal of frequency f-f 1 -2#f and zero phase. Then first and second signals are respectively mixed in mixer 5 and 6 with the signals (f+#) / # 1  and (f+ #) / # 2  received by antennµ 1 and 2, to give respective signals (f 1 +#)  /# 1  and (f 1 +#- 2#f) /# 2  retaining the original phase relationship but differing in frequency by a small amount 2#f. These two signals are combined in adder 10 and the resultant composite signal is amplified at 12. The signal (f 1 +#) / # 1  is fed to a frequency spread eliminator 16 which is also fed with a signal f 2 / #. By means of an automatic frequency control system (see Fig. 3 and Specification 1,121,290) the frequency spread eliminator produces a signal (f 1  +f 2  + #) # 1  + #. The frequency is seen to contain the shift term #, such that when this signal is mixed in mixer 14 with the output of amplifier 12, the output, contains components f 2 /# and (#2 - 2#f) / #+#, not subject to the random frequency shift and allowing the use of narrow band filter in later stages with the resulting increase in accuracy. The two components are fed to a demodulator 20 which produces a signal #f/ #/2 or 2#f/ # which is fed in turn to a phase comparator 24 which produces an indication K# of the angle # and thus of the direction angle α.

Filed: 1973-05-15
Abstract: 1372168 Rotary positive-displacement machines NISSAN MOTOR CO Ltd 15 May 1973 22953/73 Heading F 1F An apex seal 22 for a rotary internal combustion engine comprises a central element 34 with undercut inclined end-faces 40, 42 on which sealingly slide inclined faces 46, 48 of end elements 36, 38. The top surface 44 of the central element is "offset" relative to the top surfaces 50, 52 of the end elements with the axis of curvature O of surface 44 and the common axis of curvature O' of surfaces 50, 52 being spaced equidistantly from, and on opposite sides of, the longitudinal bisecting plane of the apex groove. At TDC, one apex seal is in the hottest zone L and the other in a cooler zone T. In the cooler zone T the bisecting plane trails behind the normal, Fig.6, with the result that the end elements 36, 38 are relatively withdrawn radially into the groove with respect to the central element 34. However, in the hotter zone L, where the width between the end-wall faces is greater  than at zone T, the bisecting plane leads the normal and the central element is now more withdrawn into the groove than the end elements which means that a greater length l of the sealing surface engages the housing wall, Fig.9, to compensate for the greater width between the end-faces.
