Abstract: A bypass for use in packaging apparatus in which an article is carried on a first conveyor and is transferred to a second conveyor during continuous motion of the conveyors. A transfer mechanism including a cam follower is engageable by a cam track underlying the first conveyor to actuate the transfer mechanism for effecting the transfer operation. A selective direction or bypass device engages the cam follower to guide it to either engagement with the cam track to either effect a transfer operation or to bypass the cam track so that the transfer operation is not effected. The bypass device includes a guide track that engages the cam follower that is amounted on a pivot pin on a frame member of the first conveyor adjacent to the upstream ends of the first conveyor and the cam track. The guide track is movable laterally with respect to the cam track and has a quarter circular profile so as to engage the cam follower as the cam follower travels about the conveyor sprocket. The guide track is automatically pivoted in response to a sensed condition on the first and second conveyor by a pneumatic cylinder operatively connected to the guide track.

Abstract: The invention relates to an antilock system for vehicles with an electronics unit (1) which regulates the brake pressure of a monitored wheel as a function of the wheel revolutions so that locking is prevented. The system is so connected that a separate revolutions sensor is assigned to each wheel and that both wheels on an axle are subjected to a pressure medium by way of a common regulating valve (8) controlled by the electronics unit (1). This arrangement corresponds to that of a select-low control. In order to shorten the extended braking distance occurring with a select low control on road surfaces with varying coefficient of friction on either side, the control is so designed that, when a delay signal (-b) occurs, the electronics unit (1) does not switch as usual to "Reduce pressure" but the control valve (8) is switched to the "Maintain pressure" position, at least until the occurrence of a slip signal ( lambda ).

Abstract: The invention in one aspect provides a method of testing drilling mud in use which comprises periodically sampling the circulating mud and analyzing its aqueous filtrate at the rig site by ion chromatography for selected positive and negative ions; one or more other parameters of the sampled mud and/or mud filtrate (eg pH, temperature) may also be measured; preferably the composition of the mud filtrate thus monitored is interpreted to indicate downhole interactions, with the composition of the mud supplied to the hole being adjusted to or towards the optimum as drilling proceeds. The invention also provides a method in which the solids of the periodically sampled mud are analysed at the rig site, eg for sorbed ions and/or for cation exchange capacity; the values so obtained are preferably combined with those for the mud filtrate analysis and used in the diagnosis of downhole conditions for adjustment of the composition of freshly supplied mud. The invention further provides a method of analysing drilled shale solids in drilling mud in use which comprises drying and separating these solids from the mud, extracting ions from the separated solids into solution, and analysing the resulting solution by ion chromatography for selected positive and negative ions; these operations are conducted at the rig site, and the resultant data, usually along with analyses of the circulating mud composition, are preferably used to indicate appropriate adjustment of the composition of the mud supply to or towards the optimum as drilling proceeds.

Abstract: The invention relates to a method and apparatus for controlling fuel supply to an internal combustion engine. Said control apparatus includes an A/F ratio feed-back control (309) with learning function. A difference between an A/F ratio detected by an oxygen sensor and the stoichometric value is obtained and divided into an A/F ratio correction coefficient and an A/F ratio deviation coefficient in accordance with predetermined gains. The former coefficient is stored in an area of a correction map (313) corresponding to operational conditions of the engine at that time and the latter coefficient is accumulated in an additional sotrage (315). Upon determination of an amount of fuel to be supplied, an A/F ratio correction coefficient is read out from the map (313) in response to teh operational conditions and added to the latter coefficient read out from the additional storage to form a correction value by said control apparatus, which is used in fuel supply amount correction (307) for correcting a preliminary fuel supply amount obtained in accordance with the operational conditions to determine a final fuel supply amount. With this, the quick determination of the final fuel supply amount according to the operational conditions of the engine can be performed.

Abstract: To reduce their nitrogen oxide content, flue gases from burners are catalytically treated with ammonia vapour, which is fed to the flue gases via a carrier air stream. If ammonia water is used instead of pure ammonia, the water fraction must also be evaporated. Solids, which are obtained as solid residues in evaporation can be dissolved in the ammonia water. In order to avoid the separation of a solid residue stream from the process, the ammonia water is partially evaporated, the vapour formed is swirled in a hot carrier air stream and the remaining liquid is distributed in the carrier air stream with a propellant. By this means the solid residues produced in the form of fine- grained aerosols are discharged without problems in the carrier air stream. <IMAGE>

Abstract: A first film disposed in a first direction on an integrated circuit chip and having uniformly spaced taps provides progressively increasing resistance values. A second film disposed on the chip in a direction opposite to the first direction at a position displaced in any direction from the first film may have a construction corresponding to that of the first film. First and second reference voltages may be respectively applied to the first and second ends of the first and second films. Particular taps on the first film may be connected to taps in corresponding positions on the second film with corresponding voltages. A plurality of differential comparators are provided, each with a signal input and a reference input. Each comparator reference input is connected to an individual one of the taps on the first film, but not necessarily to successive taps. The reference input connections to the taps may have a non-linear (e.g. a luminance) spacing in the first direction to provide a non-linear voltage (e.g. a luminance) relationship between such taps. For low voltages, however, the reference input connections to the taps may have a linear spacing in the first direction to provide a linear voltage relationship between such taps. An input voltage is applied to the signal input of all of the comparators. Binary signals representative of the input voltage are produced by the comparator in which the input voltage is substantially equal to the reference input voltage introduced to such comparator.
