Abstract: Invented is an improved process for preparing aromatic ring-fused cyclopentane derivatives. Preferred compounds prepared by this invention are indane carboxylates and cyclopentano[b]pyridine derivatives. The most preferred compounds prepared by this inventino are (+)(1S,2R,3S)-3-[2-(2-hydroxyeth-1-yloxy)-4-methoxyphenyl]-1-(3,4-methylenedioxyphenyl)-5-(prop-1-yloxy)indane-2-carboxylic acid and pharmaceutically acceptable salts thereof and (+)(1S,2R,3S)-3-[(2-carboxymethoxy-4-methoxyphenyl)-1-(3,4-methylenedioxyphenyl)-5-(prop-1-yloxy)indane-2-carboxylic acid and pharmaceutically acceptable salts thereof. Also invented are novel intermediates useful in preparing these compounds.

Abstract: A structural member, e.g. a truss for erection of temporary structures, comprises a number of elongate elements disposed in spaced generally parallel relationship to one another with transversely extending elements therebetween, and an element extending longitudinally of the structural member has a formation extending lengthwise of it for engagement by an attachment member which is to be retained to the longitudinally extending element at any of a range of positions therealong. The attachment member may provide for connection of a safety element to the structural member, and be freely movable therealong in use.

Abstract: By sampling the initial result of a query to the database, thereby producing a sampled result which is substantially smaller than the initial result, the sampled result is easier to analyse statistically and is easier to transmit across a communications medium such as a network.

Abstract: A gas discharge tube for a gas laser includes a discharge chamber having a first end and a second end. A cathode is mounted near the first end in a cathode region of the discharge chamber and an anode is mounted near the second end. An electromagnet induces an axial magnetic field within the discharge region, and a pole piece is mounted on the end of the electromagnet adjacent the cathode region. By using a pole piece for attenuating the axial magnetic field in the cathode region, a significant reduction in 60-60 Hz modulation of the light beam is realized, as well as a reduction of sputtering in the throat region of the discharge tube, additionally, the cathode placement relative to the throat region may be optimized leading to an increase in plasma tube efficiency. In addition, a second pole piece is mounted on the end of the electromagnetic coil, adjacent the anode region, for attenuating the axial magnetic field inside the anode region after the discharge reaches the anode.
