Abstract: A gas sensor, for detecting the presence of a gas in a gas mixture, comprises two pairs of electrodes (1, 3; 2, 4) mounted on a sensing element (5) either with the electrodes of each pair spaced apart by a different amount, or with the relationship between the electrodes of one pair and the active surface of the sensing element being different in the case of each set. In use, the ratio of the electrical resistances accross the two pairs of electrodes it measured, and the measured values of this ratio are compared with a calibration curve indicating how the ratio varies with concentration of the gas to be detected.

Title: Two-stroke engine oils
Inventor: MCMAHON JOHN
IPC: C10M111/04
Filed: 1994-08-10
Granted: 2003-11-04
Abstract: This invention relates to a two-stroke engine oil which comprises polybutene base oils which are either very low in or are substantially free of n-butenes in the polymer backbone. The absence of n-butenes in the polybutenes significantly reduces smoke emission in exhaust gases generated by the use of the engine oil. Polybutenes such as ULTRAVIS~ which are substantially free of chlorine and have a high degree of terminal unsaturation are particularly preferred.

Abstract: A flat trapezoidal container provides a generally frustoconical bag with a single cavity when at least partially filled with a pulverulent material such as soil which may have a live plant growing therein, or comestible goods such as popcornand other snacks which rely heavily upon spur-of-the-moment purchases by a cus-tomer who must first be visually attracted to the goods, thereafter be visually convinced of their freshness, and have the opportunity to smell and/or touch thegoods prior to purchasing them. The container may also be specifically dimensioned to snugly sheath a flower pot so as to leave therebeneath, a surplus of film in an empty transition zone which is concealable under the flower pot. The container is made from two flat panels of heat-sealable film, each shaped as a trapezium; or from a single web folded double. The lower portion of the container is ornamentally imprinted along a border extending beneath a generally lateral line above the longi-tudinal axis of the web, to identify the contents and simulate them in their optimum condition to enhance their marketability; and, with a marker in the upper portion, quantifies the volume of the goods contained, or provides instructions for their use. When the cavity is distended by being partially filled, the entire container, except for a transition zone, presents a smoothly arcuate surface of the frustum of a cone. The lower exterior portion is continuously printed with ornamental images of thecontents, or images evocative thereof, without an interruption in the printing, such as is present as an elongated blank rectangle in prior art bags. The transparentupper portion is free from an elongated portion of the printed image near the edges, as in prior art bags. A method is disclosed for forming the printed container which method requires discarding the material for one bag for each bag made by thermally sealing the equally, but oppositely angulated sides of the trapeziums, and the shorter of the remaining parallel sides.

Abstract: The substrate (10) is placed in an enclosure (12) and is heated so as to establish therein a temperature gradient such that the substrate has a higher temperature in portions that are remote from its exposed surfaces than at its exposed surfaces. A reaction gas constituting a precursor for the material to be infiltrated is admitted into the enclosure, with formation of the material being enhanced in those portions of the substrate that are at higher temperature.      At the beginning of the infiltration process, and at least during the major portion thereof, substrate heating is controlled in such a manner as to maintain the temperature of its exposed surfaces at a value that is no greater than the minimum temperature for the reaction gas to deposit the material that is to be infiltrated, while portions of the substrate that are remote from its exposed surfaces are at a temperature that is greater than the minimum temperature for deposition.

Title: Method and apparatus for coherent communication reception in a spread-spectrum communication system
Inventor: LING FUYUN
IPC: H04B1/707
Filed: 1995-07-31
Granted: 2000-06-06
Abstract: A method and apparatus is provided for facilitating coherent communication reception. A received reference symbol coded spread-spectrum communication signal is despread with a spreading code to derive a stream of reference samples (152) and a stream of data samples (158). The channel response is estimated by utilizing the stream of reference samples (152). An offset frequency detector (443) determines an offset to be applied to the received signal via a frequency locked loop (456), while a timing control (176) compensates for slow timing drift and fast fading based on power estimates derived from the stream of reference samples (152) and or the stream of data samples (158). A rate estimator determines the rate at which the information was encoded, and the rate information is used to optimize the timing control (176), frequency offset detector (443) and channel estimator (154). Thus an improved detection of estimated data symbols from the stream of received data samples (158) is provided.

Abstract: The endless band is provided with print marks (D) at equal distances, this distance (r) corresponding to the circumference of the largest pack goods item (P) to be banded, plus an overlap. A strip-shaped glue coat (L) for closing the band loops (5a) is applied transversely to the longitudinal direction of the band at a constant predetermined distance (s) in front of each print mark (D). During banding, after the looping of the pack goods (P) the band movement is stopped when a print mark (D) is read by a print mark reader. At standstill, a glue coat (L) is located directly at the closing mechanism. While the free band end is retained, the endless band is retracted until the band loop (5a) surrounds the pack goods (P) with a specific tension.      The closing of the band loop and the severance of the latter then take place. When the circumference of a pack goods item is smaller than that of the largest pack goods item, the excess length (2x) remaining in front of the following glue coat (L) after the band loop has been severed is also banded in as an inner overlap (2x) during the banding of the following pack goods item.
