Abstract: This invention relates to a novel type of textile reinforcement adapted to be used for making laminated complexes, of the type constituted by at least one layer of reinforcing yarns. The yarns are bonded together by adhesion with binding yarns, disposed transversely, in a small proportion with respect to the reinforcing yarns. Reinforcing yarns are spaced apart from one another so as to form stable and undeformable holes of definite shape. Additional binding yarns are disposed on either side of each of the strips of reinforcing yarns.

Abstract: Griseolic acid and dihydrodesoxygriseolic acid derivatives having an alkyl or aralkyl group as a substituent on the amino group at the 6-position are prepared by reacting the unsubstituted compound with a compound R<7>-X (where R<7> is alkyl or aralkyl and X is halogen or sulfonyloxy). The group first substitutes and quaternizes the 1-nitrogen atom. The compound is then subjected to an appropriate combination of temperature and pH to cause ring cleavage, rearrangement and ring closure involving the 6-amino group and this quaternized 1-nitrogen to give a 6-alkylamino or 6-aralkylamino derivative.

Abstract: An essentially self-contained mobile tube cleaning machine (10) which is remotely operable so that there is no need for operating personnel to be in close proximity to cleaning nozzles (160) or other high pressure lines during tube cleaning operations. As a consequence, significantly higher water pressures and significantly higher water flow rates can be utilized thereby not only accelerating the rate of cleaning but also the efficiency and the effectiveness of the cleaning operation. Through the provision of a nozzle head at the end of an ar­ticulatable boom (410), it is possible to adjust the loca­tion of the nozzle (160) through movement of the boom (410) in order to clean the face of a tube bundle, the shell side of a tube bundle and the interior of the tubes themselves.

Abstract: It is desirable to provide remote digital protection of distribution transformers. A protection system is disclosed which is able to detect increases in transient D.C. current flowing in the respective phases of a distribution cable (10) feeding a transformer and also to detect increases in other selected functions of supply parameters for identifying and quantifying a fault current flowing in the distribution cable (10). Increases in these other functions are analysed to identify whether the increases indicate a fault current. Any such fault current can then be quantified and the triggering of a circuit breaker (19) initiated to isolate the supply cable on identifying a fault current. The circuit breaker (19) is not triggered for any increases in the other functions for as long as there is a detected increase in D.C. current in any phase.

Abstract: When depositing a solder layer on relatively small metallic or metallized surfaces by dipping in liquid solder, there is often in many applications the problem of uniform wetting, as a result of which the solder coating becomes defective and therefore several coating operations are required. To improve the ease with which the surfaces can be wetted, the process proposes to additionally spray the surfaces to which flux is applied beforehand with a liquid, preferably water, just before they encounter the liquid solder. In an apparatus for depositing a solder layer on the metallic surfaces of an unassembled printed circuit board (1), in which apparatus the board (1) is pushed through a wave of solder, spraying devices (11, 13) are provided at the entry side (E) above and/or below the feed plane of the board (1), the operative area of which spraying devices (11, 13) extends over the entire width of the board (1). During the passage of the board (1), the liquid is applied to it just before penetrating the wave of solder. <IMAGE>

Abstract: The flow sensor, has an electrical frequency output proportional to flow, operates by bi-stable fluidic techniques acting upon an oscillator blade (24) being in proximity to a frequency transducer (28). The oscillator blade lies within a gap (22), the fluidic boundary layers (BL) discharging from which adhere to the oscillator blade, until a wedge shaped diverted (27) forces them away to join the main media stream. Both the momentary pressure drop across the diverter and the fluidic drag of the media leaving the diverter in one of its bi-stable positions, causes the blade to move to its alternate position, where the process is repeated, causing continuous oscillation. The flow sensor may be fixed to an insertion rod into a velocity profile conditioning unit, where the mean velocity occurs within the inserted flow sensor, where fluidic processing provides accurate representation of flow in large pipes.

Abstract: Fine particle coal is beneficiated in specially designed dense medium cyclones to improve particle acceleration and enhance separation efficiency. Raw coal feed is first sized to remove fine coal particles. The coarse fraction is then separated into clean coal, middlings, and refuse. Middlings are comminuted for beneficiation with the fine fraction. The fine fraction is deslimed in a countercurrent cyclone circuit and then separated as multiple fractions of different size specifications in dense medium cyclones. The dense medium contains ultra-fine magnetite particles of a narrow size distribution which aid separation and improves magnetite recovery. Magnetite is recovered from each separated fraction independently, with non-magnetic effluent water from one fraction diluting feed to a smaller-size fraction, and improving both overall coal and magnetite recovery. Magnetite recovery is in specially designed recovery units, based on particle size, with final separation in a rougher-cleaner-scavenger circuit of magnetic drum separators incorporating a high strength rare earth magnet.

Abstract: A novel three-step process for preparing 4-(3,4-dichlorophenyl)-4-phenylbutanoic acid is disclosed, which involves (1) reducing 4-(3,4-dichlorophenyl)-4-ketobutanoic acid to 4-(3,4-dichlorophenyl)-4-hydroxybutanoic acid; (2) then converting the intermediate hydroxy acid formed in the first step to 5-(3,4-dichlorophenyl)-dihydro-2(3H)-furanone, and (3) thereafter reacting the resulting gamma-butyrolactone compound with benzene in a Friedel-Crafts type reaction to form the desired final product. The latter compound is known to be useful as an intermediate leading to 4-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenone and ultimately, to cis-(1S)(4S)-N-methyl-4-(3,4-dichlorophenyl)-1,2,3,4-tetrah ydro-1-naphthaleneamine (sertraline), which is known to be a preferred anti-depressant agent in the field of medicinal chemistry.
