Abstract: The present invention is directed to a method for making L-lactide from aqueous L-lactic acid. Aqueous lactic acid feed for present purposes comprehends an aqueous mixture of one or more of L1A, L2A, and L3A, optionally with LD being present. L-lactic acid is the preferred feed configuration for making L-lactide, and is to be understood even though the configuration symbol is not used throughout this application. Aqueous lactic acid feed is treated for removal of water therefrom until a degree of polymerization (DP) not substantially above about 2 is reached. The treatment then is ceased to produce a crude LD product. LD then is separated from the crude LD product. A preferred treatment involves heating the feed at elevated temperature to remove water. LD can be separated from the crude LD product by a variety of techniques to produce an LD-depleted product. This LD-depleted product, optionally augmented with additional aqueous lactic acid and/or water then can be readmitted to the process for making additional lactide. This cyclic or recycle process embodiment of the present invention enables very high lactide conversions to be realized.

Abstract: Implantable training appliance for a muscle, which is present for supporting the heart muscle, having a first chamber (3) which is filled with a gaseous and/or a liquid medium, has elastically deformable walls (4), and is surrounded by the muscle to be trained, and is connected to a second chamber (10, 11) which is connected to the first chamber and can exert a counterpressure on a medium flowing into the second chamber (10, 11). Through the periodic stimulation of the muscle surrounding the first chamber (3), to and fro flow of the medium between the two chambers is achieved by repeatedly compressing the first chamber (3). After sufficient muscle training the chambers are removed and the remaining hollow muscle is connected to the circulation system as a heart-supporting pump.

Abstract: A reclining modular seating section having a recliner assist apparatus for initiating reclining movement of the seating section and extending movement of a leg rest assembly thereof. The release assist apparatus includes an insert member (346) fixedly secured to a drive rod (324) of a recliner mechanism of the seating unit. A drive bracket (326) is fixedly secured to the insert member (346) and pivotally coupled to an L-shaped coupling bracket (328). The L-shaped coupling bracket (328) is in turn coupled to a biasing spring (330) which exerts a tensioning force to drive the drive bracket (326) and drive rod (324), to thereby cause the seating section to assume a reclined position with its leg rest member in an extended position when the drive bracket reaches an over center position. A release assist bracket (322) is disposed coaxially about the insert member (346) and has an end thereof coupled to a handle member (316) which is graspable by an occupant of the seating unit. By pulling on the handle member (316), the release assist bracket (322) urges the drive bracket (326) to an over center position, thereby enabling the biasing (330) spring to continue driving the drive rod (324) so as to extend a leg rest assembly and simultaneously recline a seatback portion of the seating unit. <IMAGE>

Abstract: A lampshade is manufactured by forming a sector-shaped blank (10) of heat deformable sheet material, into a hollow truncated cone having upper and lower peripheral edges. The overlapping edges (12) of the blank are fixed together. An apparatus includes an upper former (22) for engagement with the interior surface of the conical blank and a lower support (86), releasably supporting a stiffening ring (90) around its periphery, for example magnetically, so that the upper and lower marginal edge portions of the blank projects respectively beyond the upper former (22) and beyond the stiffening ring (90) supported by the support (86). Heating means (30,58) heat the marginal edge portions and upper (32) and lower (61) die members engage the heated and softened marginal edge portions to fold or roll the deformable sheet material respectively around the edge portion (25) of the upper former and around the stiffening ring (90) supported by the lower support (86) and thereafter hold the formed edge portions in place until the material has cooled. The edge portion of the material deformed around the stiffening ring (90) forms a pocket retaining it. The workpiece is removed from the apparatus after retracting the lower support (86) inwardly from the stiffening ring (90). A mounting bracket (14) is fitted, with its peripheral ring (16) being pushed into the cavity or pocket at the upper edge of the lampshade.

Abstract: A sprayable, trowelable epoxy polysiloxane based coating and flooring composition exhibiting excellent weatherability in sunlight and superior chemical, corrosion and impact resistance after curing is made up of: (a) a resin component which includes a non-aromatic epoxy resin having at least two 1,2-epoxy groups per molecule; a polysiloxane and an organooxysilane; (b) an difunctional aminosilane hardener component; (c) an organotin catalyst; and (d) an aggregate or pigment component. Organic solvents and flow modifying agents may be added to facilitate spray application. The resin component, hardener component, aggregate component and desired catalysts are combined in the presence of a sufficient amount of water to promote the hydrolysis of polysiloxane and/or organooxysilane and the polycondensation of the silanols produced by such hydrolysis. The aminosilane and epoxide resin react to form a cured linear epoxy polymer. The polysiloxane and/or organooxysilane undergo a hydrolysis reaction which produces silanol. The silanol undergoes polycondensation forming a linear epoxy-modified polysiloxane polymer.
