摘要:
A system (1) for separating a fluid stream (2) comprising gas, a light liquid and a heavy liquid, the system comprising a separation vessel (5) that is arranged to define a downwardly extending separation space and comprises a downwardly sloping tube (8), the separation space having an inlet (10) for the fluid stream at a first height, an outlet (20) for heavy liquid at a second height below the first height, an outlet (30) for light liquid at a third height between the first and second heights, an outlet (70) for gas above all outlets for liquid, wherein a further outlet (51, 56) for light liquid is provided at a fourth height between the first and third heights, and wherein at least the outlet at the third height is provided with a control valve (33) that is operative to open and close in dependence of the type of liquid in the pipes at that level, and a method of separating a fluid stream comprising gas, a light liquid and a heavy liquid in such a system, wherein an indication of height of an interface between heavy and light liquid in the separation vessel is obtained and the control valve at the third outlet is operated in dependence on the height of the interface.

The invention relates to a method of improving the growth and the feed efficiency and of increasing the muscle/fat ratio of agricultural domestic animals, in particular bovine animals and sheep, by administering to the animals a composition which comprises as an active substance a compound of the general formula ##STR1## wherein: R.sub.1 is a phenylalkyl group the alkyl group of which comprises 1-3 carbon atoms and the phenyl group of which may be substituted with one or more substituents selected from the group consisting of hydroxy, methoxy, fluoro and methylsulphonylamino, or whereinR.sub.1 is a thienyl alkyl group or a tetrahydrofurylalkyl group the alkyl group of which comprises 1-3 carbon atoms; or whereinR.sub.1 is an optionally branched alkyl group having 1-8 carbon atoms which optionally is substituted with a C.sub.1 -C.sub.4 alkoxy group, a hydroxy group, a C.sub.1 -C.sub.4 alkoxycarbonyl group or a carboxy group; and whereinR.sub.2 and R.sub.3 are each independently methyl or ethyl; or an acid addition salt of the said compound.The invention further relates to a composition, in particular intended as a feed additive, which comprises such a phenylalkylamino derivative as an active substance.
摘要:
Certain nuclear substituted benzylidene amino oxyalkyl carboxylic acids esters, amides and salts thereof have been found to have a strong anti-inflammatory activity and a potent analgetic activity. In addition, some of the compounds have an activity against Rhino virus. An example is [(4-chlorobenzylideneamino)oxy] acetic acid.
摘要:
Method and apparatus for controlling one or more first compressors (12), through which a compressor feed stream (10) is passed. At least one throttling valve (32) is provided downstream of a compressor recycle line (22), which is provided around the or each first compressor (12) and includes an in-line first recycle valve (24). Sometimes, at least a fraction of the compressor feed stream (10) is selectively allowed to bypass the or each first compressor (12) and the at least one throttling valve, via a bypass line (60). At least one of the throttling valves (32) is automatically controlled using the measurement values of at least one pressure and at least one flow of the group consisting of: the pressure (P1) of the compressor feed stream (10), the flow (F1) of the compressor feed stream (10), the pressure (P2) of the first compressed stream (20) and the flow (F2) of the first compressed stream (20). A first compressor controlled this way may be used in a method of cooling an initial hydrocarbon stream (100).
摘要:
A new Anthurium plant particularly distinguished by having pale-pink colored spathes with pink-red towards the tip and edge of the spathes, spathes that slowly turn green with age, a compact and full plant habit, rich shoot formation, and a plant height of about 40.0 cm to 50.0 cm, is disclosed.

The intra-luminal ultrasonic instrument includes a catheter comprising a body, a flexible rotatable drive shaft within the body, an opalescent tip coupled to the flexible rotatable drive shaft having a distal end and a distal end portion adapted to be introduced into a lumen and a proximal portion, and a transducer mounted in the tip for rotation at a selected rpm, the catheter having a diameter no greater than 3 millimeters, the flexible rotatable drive shaft having a central longitudinal channel containing coaxial cable cooperative with conductors to connect the transducer to a source of energy for energizing the transducer to produce and supply sound waves, and the transducer having a top surface comprising a matching layer of a conductive polymer set upon a piezo plate.
摘要:
Novel substituted-alkylidene-aminooxyalkylcarboxylic acid esters of the formula I and their acid addition salts have a strong antiinflammatory and a potent analgetic activity and a low toxicity. The substances may be used for treating rheumatic affections. They may be synthetized and formulated into preparations by known methods.
摘要:
Two amino-ethyl methylthio substituted alkylenephenone oximes have been found to exhibit antidepressive activities. The two compounds are O-(2-amino-ethyl)-4'-methylthioacetophenone oxime and O-(2-amino-ethyl)-4'-methylthiohexanophenone oxime.
