Filed: 1993-04-14
Abstract: A method and apparatus for removing sulphur from a gas stream containing at least one sulphur compound, comprising cumbusting said gas stream with an oxygen containing gas in an incinerator (10) to convert the or each sulphur compound to at least one sulphur oxide. A gas stream is then withdrawn from the incinerator, which contains the or each sulphur oxide. The sulphur oxide containing gas stream is then directed to an ab-sorber (12) having an absorbent bed adapted to remove sulphur compounds. The absorbent bed is then contacted with a hydrog-en and/or hydrocarbon containing stream to regenerate said ab-sorbent bed by reducing the sulphur compounds absorbed in said absorbent bed to hydrogen sulphide and/or sulphur diox-ide, and thereby forming off gas stream containing hydrogen sulphide and/or sulphur dioxide. Finally, sulphur is recovered from said hydrogen sulphide and/or sulphur dioxide bearing stream. The sulphur can be recovered by a Claus sulphur rec-overy process (16). The hydrogen sulphide containing gas stream can be ammonia acid gas stream, thereby causing N2 to be formed in the incinerator. The N2 is not absorbed in the ab-sorbent bed.

Title: Method for simultaneous determination of thermal conductivity and kinematic viscosity
Inventor: HORI TOMOSHIGE
IPC: G01N25/18
Filed: 1994-03-24
Abstract: ABSTRACT OF THE DISCLOSURE      A heating sensor capable of generating heat and measuring its own temperature is placed in a fluid and a thermometric sensor is placed in the fluid and inside a temperature boundary layer formed around the heating sensor upon heat generation therefrom.   A temperature of the heating sensor and a temperature of the fluid are measured.   A relationship between thermal conduc-tivity of the fluid and a differential value between the temperature of the heating sensor and the tempera-ture of the fluid is used to determine the thermal conductivity of the fluid.  Then, the heating value of the heating sensor is adjustably increased so that the thermometric sensor is positioned outside the tempera-ture boundary layer.   A temperature of the heating sensor and the temperature of the fluid are measured.          The relationship between kinematic viscosity of the fluid and a differential value between the temperature of the heating sensor and the temperature of the fluid is used to determine the kinematic viscosity of the fluid.   Alternatively, a single heating sensor and a pair of the thermometric sensors are used, where one of the thermometric sensors is placed outside the tempera-ture boundary layer, and the other thermometric sensor is placed inside the temperature boundary layer, or a pair of the heating sensors is used with a single thermometric sensor placed outside the temperature boundary layer formed around one of the heating sensors and inside the temperature boundary layer formed around the other heating sensor.

Title: Refastenable adhesive fastening systems for disposable absorbent articles
Inventor: BLANEY TED LEE
IPC: A61F13/58
Filed: 1992-10-20
Abstract: Disposable absorbent articles such as baby diapers or adult incontinent briefs provided with a refastenable adhesive fastening system. The adhesive fastening system preferably comprises a pair of tape tabs each having an adhesive surface which during use is adhered to a landing member having an adherence surface which may comprise only the backsheet that has no reinforcement for strength against tearing or may comprise a reinforced backsheet. The invention improves bond security while at the same time making the fastening system more easy to remove without tearing by careful optimization of the properties of the adhesive, the tape tab, and the landing member. In particular, it has been found that the adhesive fastening system should have a Standard Shear Hang Time of greater than about 1000 minutes per square inch. The surface characteristics, toughness, and elasticity modulus of the landing member is optimized while the adhesive aggressiveness (quick-stick) of the adhesive is optimized with preferred low coating weights of the adhesive and low calculated caliper for the landing member so as to provide an adhesive fastening system that bonds easily, holds securely and is refastenable.

IPC: H04N7/00
Filed: 1994-01-06
Abstract: During recording of a TV signal on a VCR, data is accumulated representing time of occurrence and duration of events in the television signal, and is stored in memory (42). A time code generator (50) generates time codes which are written on the tape as it is recorded. After recording, the stored data is analyzed to classify the content of the TV signal and a playback map is constructed and stored in memory (64). During playback, the map is retrieved and stored timing data are compared with timing reference data read from the tape. The VCR is fast forwarded when the tape reaches the beginning of a portion of the video signal that has been classified for elimination during playback. The VCR is put in the "play" mode when me tape reaches the end of that portion of the video signal. Since the entire TV signal is recorded, all of the signal may be viewed, even if parts have been misclassified.
