Patent EP-0087936-A2 (EP)
Inventor: DUNCAN IAN JAMES
IPC: E01H1/05
Filed: 1983-02-25
Abstract: Brush control means for controlling the operative position of a rotary brush (2) or each such brush of a road or like sweeping machine comprises an electronic control (40) operated by a driver's controller (30) for controlling the operation of a valve (50) for in turn controlling the operation of a hydraulic ram (60) connected to the brush mounting (1) for angularly moving the latter laterally about its pivotal mounting (11) from the machine. A sensor such as a linear transducer (70) operated by the ram (60) is responsive to the operative position of the brush mounting (1) as selected by the control unit (40) for operating the valve (50) to hold the ram (60) against operation and hence the brush mounting (1) against outward lateral movement from the selected position. Yieldable continuous low pressure operation (58, 57) of the brush mounting (1) in the outward direction is preferably provided whereby the mounting (1) is able to yield inwardly on the brush (2) encountering an obstacle such as a kerb. The brush mounting (1) may be also protected by a fender (80) arranged to operate a sensor or switch (90 or 98) for effecting operation of the valve (50) through the control unit (40) for causing the ram (60) to move the mounting (1 ) in negotiating an obstacle. A further sensor (170) may similarly effect ram operation of the brush mounting (1) in response to operation of the steering gear (160, 180) of the machine.

Abstract: The invention relates to a method of producing white cement in which a reducing atmosphere is maintained over the entire length of a rotary kiln and precalcination takes place in a preheater supplied with heat exhaust gases from the kiln. Additional fuel is delivered to the preheater in such quantity that the CO contained in the kiln exhaust gases is burnt. As a result the essential reduction processes take place reliably in the rotary kiln without any problems occurring in the preheater as a result of a high CO content.

Title: EEG signal analysis system

IPC: A61B5/374
Filed: 1984-08-30
Abstract: An electroencephalograph (EEG) signal analyzer (10) allows the examination of the changes in EEG cerebral activity at various sites in response to an event (e.g. a stimulus or task). The analyzer (10) includes one or more signal processing modules (16) which periodically sample the EEG signal from each of the sites, convert the sampled signals to digital sample values, and store those values. Digitized waveforms based on the stored digital sample values and having a length equal to or greater than the period of the lowest frequency of interest are transformed from the time to the frequency domain. For each of a plurality of epochs, a frequency spectrum is produced having frequency content which has a content uniquely due to the digital sample values from that epoch. A weighted mean frequency value for each site during each epoch is derived from the corresponding frequency spectrum. Based upon the weighted mean frequency values, output signals are provided to a display (22) and a printer (24) to produce graphical representations of cerebral activity with time at the various sites in response to the event.
