Abstract: A retractable awning adapted to be mounted on a supporting surface and being movable between an extended position away from the supporting surface and a retracted position adjacent to the supporting surface includes a roll bar about which an awing sheet is selectively windable with the roll bar being rotatably disposed within an elongated tubular case. The case has an elongated bead projecting away therefrom adapted to be releasably retained in a mating groove provided in a mounting rail which is securable to the supporting surface. The case carrying the roll bar for the awning is, therefore, connected to the supporting surface by a tongue-in-groove connection. An auxiliary case is suspended from the main case and is adapted to releasably retain brace members which serve to retain the outer edge of the awning sheet in a position extended away from the supporting surface when the awning is in use.

Abstract: The invention contemplates an improved binocular telescope construction of the variety wherein a bridge provides articulated connection of the two telescope systems, so that by folding at least one of these articulated systems back against a side of the bridge, the instrument may be compacted when not in use. The invention is particularly concerned with provision of a single focusing drive for the focusing optical elements of both telescope systems, the drive being operative regardless of the extent of articulated expansion or contraction of the bridge-connected systems. The invention also features provision of such focusing by movement of optical elements contained within the overall telescope-housing length, so that such length does not change in the course of focusing. Various embodiments are described.

Abstract: The process allows essentially all of the nitrogen and P.sub.2 O.sub.5 values in the treated black ammonium polyphosphate liquid to be recovered in the form of valuable clarified product. In the process, a heel of black liquid fertilizer is first clarified by a prior-art procedure using flocculants. The improvement over the prior art picks up with the byproduct tops which is then diluted with the water of formulation required to dissolve additional amounts of ammonium polyphosphate melt. This diluted liquid is filtered, the filter cake containing upwards of 99 percent of the undesirable black carbonaceous material is discarded, and the clear filtrate, which contains essentially all of the nitrogen and P.sub.2 O.sub.5 originally in the tops, is then used in lieu of the prior-art water of formulation to dissolve additional ammonium polyphosphate melt to produce more black ammonium polyphosphate liquid.

Abstract: The device includes a rigid stay-bar which is bent so as to reproduce approximately the shape of the forward part of the boat, at least one of the ends of which is connected to a torsion-bar fixed onto the grating and arranged transversely with respect to the boat. The bent central portion of the stay-bar rests against a rigid bearing surface integral with the forward portion of the boat. The stay-bar ensures the holding in position of the forward portion of the boat due to the elastic force exerted by the torsion-bar, which opposes the forces exerted by the waves to lift the forward portion of the boat.
