Inventor: SEDLMEYER ROBERT
IPC: H04B1/66
Filed: 1992-07-10
Abstract: In order to require only a relatively small increase in data rate when the number of channels of multi-channel digitalised and bit rate reduced audio signals is increased, the psychoacoustic concealment by at least part of the remaining audio channels or the redundancy of individual audio channels is taken advantage of in each individual audio channel when reducing the bit rate of audio signals having more than two audio channels. Only those parts of the concerned audio channel are transmitted or stored which are not concealed by the audio signals of other audio channels or which are contained in the audio channels for stereophonic reproduction with all types of reproduction available for selection. In addition, the used parts are transmitted or stored with a resolution only big enough for the totality of all audio channels to keep concealed the quantization noise generated during quantization in all types of reproduction available for selection.

Title: Infrared continual gas analyser uses correction circuit - eliminates errors due to changes in gas concn. and temp. of ambient air
Inventor: MERKEL WOLFGANG DIPL ING
IPC: G01N21/3504
Filed: 1993-03-08
Abstract: An infrared gas analyser continually determines the concn. of a multiatomic non-elementary gas by means of an absorption cuvette which receives the gas for analysis, two interference filters, a radiation receiver to measure the absorbed radiation, while the gas under analysis is concentrated, and a radiation receiver to generate a reference signal. The novelty is that the receiver (7,8) signals pass through an amplifier (1,2), a rectifier (3,4) low-pass filters (5,6), are then passed through a circuit (10,11), where they are corrected by a signal indicating the condition of the radiator source (13) via an amplifier (9), such that the difference at the output of the differential cirucit (12) has a constant value when no gas concn. is present and when there is a variation in the temp. of the ambient air. The radiating source (13) is activated by an electrical timing circuit (14). The signal denoting the radiating power passes through a primary resistor (15). The corrector circuits (10,11) are multiplier or divider circuits. The corrector circuits (10,11) incorporate addressable readable memory. The infrared radiation from the source (13) must pass through one or more filters (16). USE/ADVANTAGE - The equipment continually determines the concn. of a multi-atomic non-elementary gas by means of infra-red analysis. Changes in gas concns. and ambient air temp. have no effect on the accuracy of measurements.

Title: Automatically registering waste-measurement and sampling device
IPC: G01N33/18
Filed: 1993-04-30
Abstract: The invention relates to an automatically registering waste-measurement and sampling device for determining the surface waste intensity with interval sampling of waste and sediment and the collection of total waste inclusive of sediment for a subsequent laboratory analysis. It consists of a collection duct equipped with a sensor, which duct feeds the waste to a distributor with two outlets. Via subsequent dumping meters, on the one hand the interval sampling is controlled and, on the other hand, the waste intensity is measured and the filling quantity is determined. The water/sediment mixture is fed via a distributor device to the sample containers and/or the collection containers. The total process for waste measurement and sampling is controlled and regulated with computer support and can thus be matched to the respective sequence of events. Solar cells are used as power source. By doing without valves, flap-valves and nozzles, high availability and low servicing and maintenance expenditure are produced.

Title: Composite anode for sec. batteries with non-aq. electrolytes - contains alkali metal alloy powder as active material, with oxygen-contg. carbon powder and ethylene@]-propylene] copolymer binder
Inventor: MIZUMOTO MAMORU
IPC: H01M4/1395
Filed: 1993-06-17
Abstract: A composite anode for sec. batteries with non-aq. electrlytes is claimed. The anode is based on powdered alkali metal alloy (I), carbon powder (II) and a binder (III), with the alkali metal as active anode material, and the electrolyte soln. is a soln. of electrolyte in organic solvent. The carbon (II) contains oxygen atoms, with oxygen content 0.1-5 wt%. Also claimed is a process for prodn. of the anode, by mixing binder (III) (an olefin copolymer) in aromatic solvent with (I) and (II), applying the mixt. to an electrode substrate and forming the coated substrate. Also claimed are sec. batteries with non-aq. electrolytes, contg. an anode as above together with a cathode. ADVANTAGE - The binder prevents particles of (I) from falling off the anode, and the presence of (II) in the spaces between the alloy particles moderates the effect of vol. changes caused by charging and discharging and helps to maintain electrical contact between alloy particles; (II) can also adsorb and desorb (I) and thus acts as a reservoir of (I) for the charge-discharge process. The overall effect is to delay inactivation and prevent collapse of the anode and thus prolong the service life of the battery.
