Title: Method of recovering and/or obtaining a sulphur moiety
Inventor: SERRAND WILLIBALD
IPC: C01B17/04
Filed: 1992-06-19
Abstract: A method and an apparatus for recovering and/or obtaining a sulfur moiety are described. Waste gases (11) containing SOx and oxygen are contacted at elevated temperature with copper oxide supported on alumina (17 or 18) whereby the 50, is fixed as a copper sulfate compound and the resulting substantially SOx-free gases may be discharged to atmosphere (28). The supported copper sulfate compound is contacted with a reducing gas (e.g., a hydrocarbon gas and/or H2S (30, 79)) and thereby convened to re-usable copper oxide with the liberation of sulfur moiety (34) in at least one of the following forms: elemental sulfur, H2S or SO2. SO2 is reacted (60, 51) with H2S to produce elemental sulfur (43). Any 502 remaining (36, 39, 50) is reacted with H2S (62) in a Claus reactor (51, 60) and elemental sulfur is recovered (43). SO2-free gases (54) are recirculated (54) to mix with waste gases (11) or discharged to atmosphere (28). The waste gases (11) containing SOx and oxygen may be from a chemical and/or catalytic conversion step, e.g., the regenerator of a fluidised catalytic cracker. <IMAGE>

Title: Locating failed fuel elements
Inventor: LENNOX THOMAS ANDREW
IPC: G21C17/04
Filed: 1992-09-16
Abstract: In a method for locating sheathing failure of a fuel element in a nuclear reactor, long-lived fission products or tag gas released from the failed element subjected to local heating are detected. The fission products or tag gas are routed to the detector by an articulated sweep arm (17) which has a coolant flow restrictor and flow guide arrangement (25) at its end. The sweep arm is used to position the restrictor/guide above selected fuel sub- assemblies (5) in turn. The presence of the coolant flow restrictor causes a local increase in fuel temperature and hence induces release of the long-lived fission products or tag gas from the leaking element. Alternatively, the local increase in fuel temperature may be caused by partial withdrawal of one or more absorber rods from the core. <IMAGE>

Title: Spinning cycle control in a drum washing machine
Inventor: BLAUERT PETER
IPC: D06F33/40
Filed: 1993-09-03
Abstract: A method of operating a drum washing machine comprises driving the drum at a predetermined rotational speed (nU) which is below the resonance speed and when the laundry lies against the inner circumference of the drum, the imbalance of the laden drum being measured. Subsequently, the main spinning phase is carried out at a final speed which is above the resonance speed and is set, in dependence on the measured amount of imbalance, between two limit values (tSE1, tSE2). The spinning phase is also variable in respect of rate ( alpha ) of acceleration to the final speed and spinning duration (tSB to tSE). The setting of rate of acceleration and spinning duration can be carried out in dependence on laundry quantity and/or laundry kind making up the drum load. <IMAGE>

Title: Commodity metering apparatus
Inventor: PAXTON-WHITE MICHAEL
IPC: G01R11/24
Filed: 1993-09-24
Abstract: A consumer meter 2 is located at a consumer's premises and a fraud meter 4 is located remotely therefrom. Supplied energy is first metered by the remote fraud meter 4 and is then measured by the consumer meter 2. The fraud meter 4 requests from the consumer meter 2 an identity code and key which it uses to encrypt the value of the measured energy prior to transmitting it to the consumer meter at the request of the consumer meter. In this way the communications link being in digital form is immune to RF interference and possible tampering by the use of RF devices. The energy values stored in the consumer's meter 2 and the fraud meter 4 may be read directly from the meters or may be transmitted, for example, via mains signalling back to the energy supply for analysis. <IMAGE>

Abstract: Encapsulation molding equipment includes individual mold bases (12, Fig 3) each having an elongated shallow recess 26 which receives strip-like carriers 32 supporting semi-conductor chips and like objects for encapsulation, the carriers being retained, in turn, on bonding or support bars 30. Cavity inserts 29 having various numbers of cavities of different size and dimension individual to carriers having like numbers of chips of a range of size and dimension fit over the strips with each cavity on an insert surrounding the chip to be encapsulated. Gate and vent passages (52, 54: Fig 8A not shown) are formed on the surface of the insert spaced away from the support bar for supply of resin from a central resin receptacle. Gate passages in the cavity inserts are configured to provide a restriction at the edge of each mold cavity, thereby accelerating the flow of liquid resin, rapidly filling the cavities and avoiding the entrapment of gas bubbles. The inserts have mold vent passages which allow for rapid venting of displaced gases from the cavities. The mold is completed by an upper mold insert plate which closes the mold and effects a seal between the mold parts and provides for delivery of encapsulating resin to the cavities in the cavity inserts. Each support bar has a plurality of recesses, each of which receives a carrier strip and a cavity insert. <IMAGE>

Title: Light scattering smoke detector
Inventor: NAGASHIMA TETSUYA
IPC: G08B17/107
Filed: 1994-03-28
Abstract: A smoke detector has a plurality of labyrinth members (9) forming smoke inlet passages which block ingress of external light, a central smoke detecting chamber, a light emitter (12) and a light detector (13) disposed so that their optical axes intersect at the centre of the smoke detecting chamber, and a light shield (14) for preventing emitter light reaching the detector directly. The end (92) of a labyrinth member adjacent to the smoke detecting chamber is bent so that a side (93) lies parallel to a side (91) of an adjacent labyrinth member. Light from the emitter entering the passage (95) so formed between adjacent labyrinth members is repeatedly reflected away from the detecting chamber, therefore lowering the zero-point level output for light scattered by smoke and enhancing the reliability of the smoke detector. The outer end of the labyrinth member may be bent to increase light reflections and consequent attenuation.
