Title: Electrical systems for road vehicles
IPC: B60R16/03
Filed: 1970-12-28
Abstract: An electrical system for a road vehicle includes a signal producing means which operates in a cycle to scan a number of switches in turn. If any switch is closed, a signal is supplied to a feed line, and this signal operates a load which is to be controlled by the switch which is closed. The load remains energized for a period of time longer than the scanning time of the signal producing means, and so as long as a switch remains closed, its load will remain energized, although only one feed line is necessary to conduct power to the load.

Title: Tamping apparatus on a refuse-collecting vehicle
IPC: B65F3/20
Filed: 1977-11-08
Abstract: The pushing-in apparatus on a refuse vehicle having a collecting box (2) and a filling trough (4) which is arranged behind the latter and has a curved and arched floor part (6), has a pivotable conveying slide (9) which raises the refuse (22), which has been collected in the filling trough, to the level of the floor (2a) of the collecting box. Here, the refuse is accepted by a pivotable pushing-in plate (19) and pushed into the collecting box (2). In order to prevent, when the conveying slide (9) is raised, the pushing of residual refuse (22a) in the filling trough (4) backwards onto the floor part (6b) by the conveying slide (9) when the latter makes its return movement, the conveying slide (9) has two parts. It has an inner wall part (8a) and an outer pivot plate (11) having a wall part (11a). The pivot plate (11) is pivoted backwards during the return movement of the conveying slide (9) so that it does not come into contact with the residual refuse (22a). Before commencement of the conveying stroke of the slide (9), the pivot plate (11) is then pivoted into the conveying position, so that it pushes the residual refuse (22a) upwards together with the refuse (22) which has just been poured in.

Abstract: A control is provided for a wire coating line which includes means for driving wire along a path at controllable speed while coating it with plastic extruded at a controlled rate and temperature, and cooling means are located at a controllable distance from the coating means to solidify the plastic. The controllable factors affect both the capacitance and diameter of the wire produced. The control allows the line to be run in accord with stored digital values for the matters to be controlled. Closed loop control is provided because the relevant factors of line operation are measured, the analogue measurements converted to digital values and compared with the stored values to produce a control signal which has the effect of reducing the differences between a desired and measured line condition as represented by the digital values compared. Closed loop control is also provided for control of the line to produce desired capacitance or diameter values in the coated wire. Whichever of capacitance or diameter is used as the basis for line control is measured and provided as a digital value to the control. This digital value is compared to a stored digital value representative of the desired capacitance or diameter. The results of the comparison is used to update the stored digital value for an operating condition of the line so that the parameter is altered to provide an operating condition which brings the capacitance or diameter closer to the desired value.

Patent ES-482203-A1 (ES)
Title: Method and apparatus for control of electrowinning of zinc
IPC: C25C1/16
Filed: 1979-07-04
Abstract: A method is disclosed for controlling a process for the recovery of zinc from zinc sulfate electrowinning solutions containing concentrations of impurities. The disclosed method includes the steps of establishing a test circuit comprising a test cell, a sample of electrowinning solution, a cathode, an anode and a reference electrode immersed in said sample, a variable voltage source and measuring means electrically connected to the electrodes. A potential is applied to the electrodes in the test cell to obtain a predetermined potential between the cathode and the reference electrode. The potential is decreased from the predetermined value at substantially zero current, the decreasing potential is measured, and the decreasing of the potential is terminated at a value corresponding to the point at which zinc starts to deposit on the cathode and the measured electrode current density increases rapidly from a value of substantially zero for further small decreases in potential. The activation over-potential is determined and is related to the concentration of impurities in the sample, whereupon the process for the recovery of zinc is adjusted to obtain optimum zinc recovery.
