Patent EP-0486164-A1 (EP)
Inventor: HODGE STEVE
IPC: F04C2/00
Filed: 1991-10-22
Abstract: A gerotor pump comprises the usual lobed annulus 30 containing the lobed rotor (not shown in Figure 2) which is journalled on cylindrical boss 36. The boss is free to turn on the eccentric pin 38 between positions controlled by limit pin 42 encountering end abutments. This enables the pump to automatically adjust to the variable direction of drive of the annulus - in this case via coupling 32 - so as to be unidirectional in fluid output via flow passages 16 18.

Abstract: A frequency stabilized optical signal source is provided. A laser (10) produces an optical carrier at a wavelength λ. Feedback is provided to adjust the wavelength λ. In order to provide the feedback, a portion of the optical carrier is modulated by a periodic reference signal (wrf). An optical fiber (16) with an in-fiber resonator (18) is coupled to receive the modulated optical carrier. The resonator effects a phase and/or amplitude change between the modulated optical carrier and a sideband thereof at a resonant frequency of the resonator. The phase or amplitude change is detected and used to adjust the laser wavelength. In a preferred embodiment, a moire grating having a single resonant frequency is used as the in-fiber resonator. The feedback scheme can lock either to the carrier frequency itself, or to a selected sideband of the modulated optical carrier.
