Abstract: A biodegradable latex web material suitable as a replacement for plastic in a wide variety of uses due to its good overall strength and its ratio of wet strength to dry strength. The material includes a web of cellulose fibers which, prior to treatment with a saturant, has a breaking length in the dry state ranging from 0.80 to 6.20 km. Optionally, the web can contain synthetic fibers to improve the tear strength of the material. In order to obtain tensile strengths which are comparable to plastics,the fibrous web is saturated with a latex composition which may be natural, synthetic or a combination of natural and synthetic polymers. In addition to latex, other additives may be incorporated into the saturant for special end use properties. The latexes used will have glass transition temperatures (Tg) of between -50°C and 20°C. If mixing natural and synthetic polymers together, the ratio of synthetic to natural polymers should be 2:1 to 4:1 by weight. The saturant compositions are applied to the base web at an add on from 16 to 80 dry parts saturant per 100 parts fiber by weight to form a latex web composite. The composite once formed should have an average strength of at least about 50 kg/cm² and a ratio of wet strength to dry strength ranging from 0.2 to 0.6.

Abstract: A method for decoding information contained in an analog waveform representative of a bar code symbol comprising the steps of identifying a decodable portion of an analog waveform; processing said decodable portion to obtain a plurality of waveform descriptors; and performing a high and low density decoding process to one or more of said plurality of waveform descriptors for decoding information contained in either a high or low density symbol respectively, is disclosed. The high density decoder used for decoding high density symbols utilizes extrema extents, i.e., areas of the peaks and valleys of the analog waveform which directly correlate to the size of the bars/spaces of a high density bar code. After locating the seed point of the waveform, each extrema extent is generated and thresholded at each peak/valley location to decide its size. The high density decoder is adaptive in that the thresholding extent value is updated as the solution grows away from the seed point. The low density decoder used for decoding low density symbols utilizes the widths of the peaks/valleys for decoding purposes and utilizes a histogramming and backtracking technique for removing noise levels from the analog waveform. Backtracking allows another decode attempt to be made if one is unsuccessful.

Abstract: A gas turbine operating on a recuperative gas turbine cycle includes a compressor (12) having liquid feed means for feeding water (22) into air compressed during compression and intercooling means (24, 26) for cooling compressed air between compression stages. A heat exchanger (28) provides for heating of compressed air by hot exhaust gases from the power generating turbine (32) of the gas turbine, before the compressed air is fed into a combustion chamber (40) where it is mixed with fuel and the fuel is combusted for generating pressure/heat energy for driving the power generating turbine. The intercooling of air compressed in the compressor together with air cooling as a result of water vaporization and simultaneous vapour loading of the air, and the employment of hot exhaust gases for heating compressed air, result in a gas turbine cycle that can provide a gas turbine having a high thermal efficiency.

Abstract: This invention relates to a method and apparatus for accessing customer meters (50) and for controlling devices (48) over a telephone line. A suppressed ringing connection is established over a customer line between a central office (21) and customer station equipment. The connection is between a data accessing device such as a meter reading controller and a customer premises device such as a meter interface unit (30). Signals are exchanged over the connection between these two units without alerting the customer via a ringing signal and without changing the supervisory state of the customer's station equipment from on-hook. The connection can also be used for controlling devices such as air conditioning units, in order, for example, to avoid overloads in a power distribution system. The voice switching network (23) of the central office is used for making the connection between the meter control unit and the meter interface unit. Advantageously, this arrangement can allow a large number of utility meters and controlling devices to be accessed remotely using existing telephone plant.

Abstract: The detector identifies and indicates a change in the temperature conditions occurring at any stage of a heating cycle by the crossing of an allowable temperature threshold, positive or negative, particularly during the storage of tinned foods. The detector is characterised in that it combines the following features:   (a) it consists of a closed jacket (4), transparent over at least one face, (b) the jacket contains an indicator (1), coloured in particular, chosen to have a melting point which is appropriately the same as the temperature threshold, (c) the jacket contains an absorbent medium in the form of a sheet (3) which can absorb the said coloured indicator if and when it changes to the liquid state, and which changes colour after being impregnated, in particular taking on the colour of the indicator, (d) the said jacket (4) contains or incorporates an opaque covering sheet (5), visible from the outside and superimposed on the visible face of the absorbent medium. The said covering sheet has open areas (6, 6') defining windows through which the absorbent medium can be seen from the outside, and areas obscuring the said medium. The colour change in the absorbent medium after the indicator has been absorbed therefore appears only in the said windows, and this conclusively reveals the change in the temperature cycle whatever the subsequent conditions.   <IMAGE>
