Abstract: An inclination sensor is disclosed which includes a capsule 15 containing a conductive liquid 17 which forms a liquid pendulum and having first and second resistive tracks 11, 13. In a first measuring configuration the terminals A, B of track 11 are connected to positive and negative voltages respectively and the terminals C, D of resistive track 13 are connected together, to form a sensing electrode. The voltage at terminal B is then adjusted so that the voltage at common electrode C, D, sensed through the conductive liquid 17 is adjusted to be zero. The ratio of voltages at terminals A and B is then related to the position of the conductive liquid 17 relative to the resistive track 11 and thus of the inclination of the capsule relative to horizontal. In an alternative measuring configuration, the roles of the resistive tracks 11, 13 are reversed, to allow the sensor to measure angles in a different angular range.

Abstract: An adjustable non-return ball valve for connection in a pipeline includes an elongate unobstructed main housing (14) arranged (16, 18) to be connected at each end to flow pipes (10, 12). There is an auxiliary housing (20) located intermediate the ends of the main housing (14) which has a longitudinal axis obtuse to the longitudinal axis of the main housing (14). There is a removable circular valve seat (38) extending across the main housing (14) at an obtuse angle relative thereto. The main housing (14) is formed in two sections (14a, 14b) which are joined together at the plane of the valve seat (38). A ball (24) is positioned to close upon the valve seat (38) and is loosely entrapped in the auxiliary housing (20) to allow flow in only one direction through the main housing (14), in which event, and in use, the ball (24) automatically rides up in the auxiliary housing (20) and away from the valve seat (38). The ball (24) and the auxiliary housing (20) having diameters greater than the diameter of the main housing (14), thereby preventing the ball (24) from moving through the main housing (14). The junction of the auxiliary housing (20) and the main housing (14) forms a ramp (34) to assist in moving the ball (24) into the auxiliary housing (20) in response to flow through the main housing (14). There is an adjustable, mechanically operable closure device (30) for the valve which fits at an upper end of the auxiliary housing (20) and is arranged to urge and hold the ball (24) downwards toward the valve seat (38) to throttle or close off the valve according to the setting of the closure device (30).

Abstract: A system determines the movement of a track vehicle along the ground, the track vehicle having at least a first rotatable, endless track for supporting the vehicle on the ground, a drive for causing the movement of the vehicle, and a turning system for changing the direction of the movement of the vehicle. The system has a first traction-improvement device for mounting on the track vehicle.

A first speed sensor for mounting on the track vehicle in the vicinity of the small-surface portion on the opposite side of the first track senses the speed of movement of the track vehicle along the ground only in the direction of the rotation of the first track and provides a first information thereof, whereby the movement of the track vehicle may be deduced therefrom. Preferably the vehicle has two tracks, and the system has two such traction-improvement devices and speed sensors respectively for the two tracks.

Abstract: This device for an upright piano has a second escapement jack (14). This jack is fixed to the check (9). It can swing about a pivot (16). At one end (15) it extends towards the hammer shank (3) and in the other direction has an end (21). A trigger stop (22), in the form of a button, is fixed to a bar (23) above the second jack. After the first jack (2) has thrown the hammer towards the string (4), it leaves its point of support beneath the butt, through the action of the set-off button (8) on the escapement lever (7). If after striking the string the hammer falls back faster than the key (1) rises, the first jack does not move back under the butt (11). The shank of the hammer then falls onto the end (15) of the second jack. It is then possible, even if the key is allowed to rise only very slightly, to throw the hammer back again by means of the second jack, even if the first jack has not moved back under the butt. At its end of travel, the end (21) of the second jack, which rises with the check, meets the stop (22), and the end (15) rises sharply and lets the hammer reach the end of its travel under its own momentum. A spring (24) restores the second jack to position as soon as pressure on the key is relaxed. <IMAGE>

Granted: 1992-09-30
Abstract: The fume purification installation is useful for removing toxic material from fumes discharged from boilers, in particular from business and residential buildings. The installation consists of a closed loop system, in which the fumes are washed with a Ca(OH)2-lye. In the lye containing the absorbed pollutents sulphite ions are in particular oxidized during the return flow through the oxygen in the air in order to obtain sulfate ions. Calcium sulphate is precipitated, forming sludge in the regenerating part of the installation; from time to time this sludge must be removed. The Ca(OH)2 extracted is continuously replaced by a corresponding quantity of calcinated limestone. The system enables efficient fume purification and calls for only minimum maintenance. Since the sediment formed contains no toxic materials, it may be discharged without constituting a hazard to the environment.

Title: Process for driving computer-controlled final control elements and computer coupled to a final control element
IPC: F02D41/26
Filed: 1987-11-11
Granted: 1990-09-05
Abstract: In all processes used until now to drive a computer-controlled final control element in connection with a self-test of the computer, the final control element is at first maintained in a defined reference position and is only released to receive driving signals from the computer once the self-test has been completed. This results however in very long delays in the case of complex computer systems. According to the invention, the final control element is maintained in a fixed position only during a first part of the self-test, and is then driven by a temporary driving signal until the end of a second part of the self-test or until a failure is detected, whichever occurs first.

Title: Spacecraft with modulated thrust electrostatic ion thruster and associated method
IPC: F03H1/00
Filed: 1988-03-21
Granted: 1992-09-02
Abstract: An axial electrostatic ion thruster (10) for use on a dual-spin stabilized spacecraft (70) is disclosed. The thruster (10) is mounted on the spun portion (72) of the spacecraft (70) and continuously fired for an integral number of spin periods to provide north-south velocity and attitude control. To achieve zero attitude precession with a statically imbalanced despun platform (74) or an intentional attitude precession generally, the ion thrust is spin-synchronously varied between two non-zero levels to achieve a prescribed Fourier component amplitude and phase at the spin frequency. Modulation of the thrust is achieved with constant ion beam current by complementary modulation of the beam voltage, VB, and accel voltage, VA by varying the ion extraction system grid voltages. This varies the thrust while maintaining a constant total accelerating voltage VTOT = VB + |VA|.
