Title: Process for the Production of Electrochemically Active Lead Dioxide
IPC: H01M4/56
Filed: 1979-06-06
Abstract: Electrochemically active lead dioxide is produced by forming an aqueous suspension of an oxidizable lead substrate, adjusting its pH to a value in the alkaline range between about 10 and 14, and then oxidising with gaseous ozone. The pH value is preferably held constant during the oxidation treatment, by adding alkali or by buffering, and the oxidation treatment is preferably carried out at an elevated temperature of about 70 to 80 DEG C. Finely divided or dissolved inoculating metals may be added to the suspension, when a corresponding inoculation is desired for the electrochemical use of the resulting lead dioxide. Finely divided inert substances, such as carbon, glass or plastics in powder or fibre form, may be added to the suspension, in order to make a lead dioxide which can be compressed to a mass of high strength for use in an accumulator or the like.

Title: Determining the energy expended in grinding
IPC: G01N33/10
Filed: 1979-07-24
Abstract: A method of automatically providing an indication of the milling energy required to grind a predetermined amount of a sample of material, e.g. a barley cultivar, in a grinding mill having grinding members rotatable within a grinding chamber comprises obtaining first and second electrical signals representative of the rotational speeds of the grinding members at two instants of time, a known period of time apart, in the grinding operation. The speed of the grinding members is measured by a photoelectric displacement encoder 8, 9, monitoring the passage of holes in a flywheel 6 driven with the grinding mill. The slowing down of the flywheel due to friction is first measured without a sample. Subsequently, the slowing down due to friction and energy for grinding is measured with a sample present. A microprocessor performs the required calculations. <IMAGE>

Patent GB-2071468-A (GB)
Title: Improvements in or relating to transversal equalisers
IPC: H04L25/06
Filed: 1980-09-04
Abstract: The presence of a d.c. offset in the input signal to an adaptive equaliser for a high speed modem must be removed before a valid signal enters the equaliser if the "coefficient up-date" algorithm for the equaliser is not to be confused. Normally the d.c. compensation is achieved using adjust-on-test resistors or potentiometers which provide for in life adjustments to compensate for ageing drift. The submission envisages the use of an additional adaptive equaliser tap-stage connected to a fixed voltage source V. This voltage is multiplied by the additional tap-stage multiplier M4 and summed with the outputs of the other tap-stages in the equalisers accumulator A. The error EK produced from the equaliser decision circuit D is correlated with the fixed voltage in the additional tap-stage correlator C4 the output of which controls the gain of the additional tap- stage multiplier thereby compensating for the original d.c. offset of the output of the equaliser accumulator. <IMAGE>
