Granted: 1989-11-14
Abstract: PHN 11 762 ABSTRACT: Device for indicating the charge status of a battery. For determining the charge status of a battery (4) when it is discharged by a load (XL) and/or when it is charged by a power-supply circuit (1) a value representing the nominal charging time and discharging time respectively and stored in first (10) and second adjusting means (11) respectively is applied to computing means (12). On the basis of clock pulses applied to the computing means (12) by the clock means (13) the computing means calculate the charge status of the battery by expressing the elapsed discharging or charging time as a faction of the adjusted discharging time and charging time respectively, which computed charge status is indicated by indicator means (14). During discharging and charging an actual charge status is detected by first (7) and second (6) detection means. In the case of a difference between the computed and the actual charge status correction means (15) correct the computed charge status and the value stored in the adjusting means (10, 11) is updated, so that during a subsequent discharging a charging cycle the computed charge status is better in conformity with the actual charge status.

Abstract: ABSTRACT            The invention relates to a method for cleaning exhaust gases weak in sulphur dioxide, or sulphur dioxide and hydrogen sulphide.  In order to remove the sulphur content of an exhaust gas, the exhaust gas is absorbed into a solution containing sulphide.  Thereafter into the solution is added an agent which causes any unstable compounds of sulphur and oxygen, such as thiosulphate and polythionates, which are formed in the scrubbing solution, to decompose into elemental sulphur and sulphate in the autoclave whereinto the scrubbing solution is fed.  The pH of the solution emerging from the autoclave is adjusted to stay within the range 2,0 - 2,9.

A plurality of gating mechanisms (90) individually coupled to the filter signals pass an output signal at a level above the perceptual level of the person when the filtered signal is above a predetermined level. The predetermined level is individually determined such that the output is past above the perceptual level only when the level of the filtered signal to which the gating means is coupled is likely to be among the larges of the filtered signals of all of the plurality of filters (88). Thus the multichannel signal processor (10) in auditory prosthesis (68) can have a combined stimulated signal which contains some, but not all, channels, namely those channels whose amplitude of signal is likely to rank among the highest compared to the amplitude of the remaining channels. In a preferred embodiment, such a channel dominant signal processor (10) will help preserve periodicities created by sharply tuned band pass filters (88).

Granted: 1992-05-26
Abstract: ABSTRACT OF THE DISCLOSURE The invention is a method for the on-line nondestructive determination of the internal bond strength of composite panel products. The method involves impinging an ultrasound pulse against the panel by R first transducer and receiving a transmitted pulse at a second transducer. The received signal strength, temperature and panel thickness are entered into an algorithm from which the internal bond may be calculated. Preferably the receiving transducer is located on the opposite side of the panel and displaced somewhat from the first transducer. The inclusion of temperature and panel thickness as independent variables greatly improves the accuracy over that available from uncorrected ultrasound testing.

Title: Vertical axis wind turbine
Inventor: DANSON DAVID P
IPC: F03D7/06
Filed: 1988-07-19
Granted: 1991-07-30
Abstract: ABSTRACT OF THE DISCLOSURE     A cross-wind, axis-type, wind turbine is provided herein, which includes four wind driven airfoil blades pivotally con-nected between upper and lower sets of support spokes supported on a rotating vertical column so that the blades are upwardly inclined towards the column axis to produce an accelerated down-wardly swirling air flow in the turbine interior.  The lower spokes are airfoil-shaped to draw wind into the turbine further to accelerate the air flow in the turbine for improved blade efficiency.  A feedback control arrangement, which is responsive to changes in wind speed or direction, adjusts the blade angles to the wind for optimum efficiency by virtue of a rack and pinion assembly connecting each blade to a center plate through con-necting rods extending radially through each upper spoke.  The center plate is mounted within the column on a control shaft that includes an offset portion that pivots during blade rotation about the column, or when rotated by a wind vane, to vary the radial positions of the plate and thereby the blades through the rack connections.  Alternatively, a pair of weights radially movable within the lower spokes by centrific force in response to variations in wind velocity can be connected to pivot the control shaft to adjust the blade angles.  Each blade includes a series of troughs formed equispaced to each other along the blade length that are respectively tapered towards the leading edge to cause wind entering the troughs to diverge and decelerate for maximum wind energy transfer to the blades.

All of the contactors in the various sets are arranged to have a fixed "at rest" position from which they move.  Under the influence of a control device         , the contactors individually and pivotally move through varying angles from their respective at rest positions to contact and fold the sheet.  The incremental angular displacement of each contactor is such that the leading edge of a sheet progressing from one contactor station to the next downstream station hill not be distorted.  Any group of contactors in contact with the sheet at and given time thoughout the cycle are disposed in a straight line to provide support for the folding portion along its entire length.  The sheet infeed set of contactors is such that each contactor         has the same at rest position - normally horizontal or 0°.
