IPC: G01C17/28
Filed: 1978-10-30
Abstract: A gyroscopic device of the type having a short-circuited rotor winding or conductor (10) so shaped so as to produce axial and radial flux components when rotated in the earth's magnetic field is coupled to a coaxial sensing coil (15) coaxial which gyroscopically stabilized thereby, signals induced in the sensing coil due to the axial flux component of the rotor is used to derive magnetic heading information and there is provided at least one further coil (41) on the supporting body and inductively linked to the sensing coil and rotor such that when the sensing coil is gyroscopically stabilized by the rotor, the coil supported on the supporting body in relation to the gyroscopically stabilized sensing coil is such that any changes in angular orientation of the supporting body relative to the gyroscopically stabilized sensing coil introduces changes in the signal voltages induced in the coils. The further coil on the supporting body may be excited with one or more excitation signals of a frequency different than the angular speed of the rotor (10) and constituted by pairs of orthogonally related coils on all three axes, namely, the roll (41, 42), pitch (43, 44) and yaw (45, 46) axes. The coil located on the yaw axis is coaxial with the gyroscopically stabilized sensing coil in the rest position and is used for eliminating ambiguities. <IMAGE>

Title: Servo-system
Inventor: WU LIN FRANK
IPC: G05B19/39
Filed: 1980-03-20
Abstract: In one embodiment (Fig. 2) of a dual-mode servo-system a movable member is driven by control signals derived from actual velocity feedback signals during coarse mode operation. At the beginning of fine mode operation the actual velocity signal is sampled and an RC circuit generates a synthetic velocity signal used to control motion of the member during final deceleration, along with an actual position feedback signal, the synthetic velocity signal having a decreasing magnitude tailored to a particular application. At a predetermined maximum time period, after detent of the member, a time out circuit re-inserts the actual velocity feedback signal. In an alternative embodiment (Fig. 5) control signals for the driven member are derived from the actual motor current by integrating the motor current, the integrated current signals being used to control motion of the member during coarse mode operation only. During fine mode operation, the member is controlled by an actual position feedback signal and an actual velocity signal derived from the position signal. The invention may be applied to carriage motion or a daisy wheel in a printer.

Patent GB-2074248-A (GB)
Title: Rotary positive-displacement pumps
IPC: F04C25/02
Filed: 1981-04-16
Abstract: A rotary vacuum pump is proposed, having a rotor with vanes which rotates eccentrically within a housing bore. Each vane is coupled with a body which is ineffective at relatively low pump rpm; however, at higher rpm, the body engages the vane in such a manner that it removes the vane from its track within the housing bore. In this manner, an rpm-dependent shutoff device is created for the pump. In cooperation with the furnishing of underpressure as an auxiliary pressure in motor vehicles, the pump is used to supplement the underpressure which prevails when the internal combustion engine is at low, idling rpm; this prevailing underpressure is at a very low pressure level, and so when it is thus supplemented there is sufficient auxiliary vacuum force available over the entire rpm range.
