Title: Method and circuitry for controlling the consistency of fresh concrete in a fixed concrete mixing device
IPC: B28C7/02
Filed: 1987-09-03
Granted: 1991-01-02
Abstract: According to the method of the invention, the final power value which occurs at the end of the mixing process is forecast during the mixing process as early as the water inflow phase with a discrete Kalman filter, using a relationship between the mean power value of the mixing motor, which correlates with the consistency, and the quantity of water currently admixed. This forecast final power value is compared to a desired final power value, which is fixed as a device and formulation parameter, and the difference is used to determine the residual quantity of water required and hence for controlling the water valve. The circuitry consists essentially of an active-power measuring device (13), which is connected via a time-controlled electronic change-over switch (14) to a first-order Kalman filter (15) or via measuring-transducer units (16, 17) to a third-order Kalman filter (20) and a circuit (23) for determining the final value. The signal present at the output of the circuit (23) for determining the final value, which signal characterises the consistency, is compared to a device and formulation parameter, fixed in a read-only memory, (25) by means of a differential amplifier (24). An evaluation circuit (27) uses the difference to derive the water-valve control times of the mixing installation (5).

Abstract: A hand-brake assembly for a vehicle comprising: a hand-actuable lever (11) mounted on a body (10) for angular movement between rest and operative positions for applying tension to a brake cable (14); a releasable engagement device (20, 12') for releasable engagement between the lever and attachment means (15) for the cable, the device comprising an elongate member (12) defining a rack (12') and an angularly movable means defining a first pawl (20) releasably engageable with the rack; catch means comprising a second pawl (40) engageable with the said rack for holding the brake cable in the tensioned position; and releasable means (45, 43) for releasing the catch means to release the brake cable; the device being engaged as the lever moves towards the operative position and disengaged as the lever moves towards the rest position, and the catch means holding the brake cable independently of the angular position of the lever. The brake lever is thus conveniently out of the user's way even when the brake is applied. By using the same rack in the engagement device and the catch, a neat assembly may be provided.

Abstract: This invention relates to the field of abrasive flow machining, particularly to a process for abrading internal surfaces of fluid flow orifices (10), (11) by contacting those surfaces with a visco-elastic plastic abrasive medium under pressure. The completion of the abrasive treatment is determined by first determining a target flow resistance, followed by monitoring the dynamic flow resistance during machining, and stopping the abrasive treatment when the dynamic flow resistance equals the target flow resistance. Fluid flow through orifices (10), (11) particularly where flow rates are to be controlled or metered, is improved. An article possessing such a metered orifice is also claimed.
