Abstract: A cardiac valve prosthesis (1) comrises an annular frame (2) through which blood can flow and a valve sleeve (11,12) of biological tissue with a plurality of valve flaps (14) which can be forced apart by the blood passing through the prosthesis (1) in one direction and which prevent the blood flow in the opposite direction, being brought into a mutually mating position under the pressure exerted by the blood itself. τheframe of the prosthesis includes a rigid or semi-rigid stent (2) constituted by a tubular body with a ring of apertures (5) and with first (2a) and second (2b) end edges which, in the implanted position of the prosthesis, are respectively upstream and downstream with respect to the direction of flow of the blood through the prosthesis. The tubular body also has integral axial appendages (4) each of which has respective apertures (6) adjacent its free edge. A covering of biocompatible textile (71, 72, 73) completely covers the rigid stent (2): the covering has associated suture stitches some (92, 93) of which extend through the apertures (5) of the said ring to attach the covering (7) to the stent (2) itself. The valve sleeve includes two sheets of biological tissue (11, 12) sutured (13) together and wound into a tube, the radially outermost one (11) having a shape which substantially reproduced the shape of the stent (2) of the frame and the radially innermost one (12) whereof, carrying the valve flaps (14), has a collar end portion (15) which can be turned outwardly of the frame (2, 7) at the first end edge (2a) of the stent (3) of the frame (2, 7). The valve sleeve is fixed to the frame by further suture stitches, some (10) of which extend through the apertures (16) in the ends of the appendages (4) of the frame stent. Other suture stitches (121) connect the end edge of the collar end portion (15) of the radially inner sheetto the covering of biocompatible textile.

Abstract: The biological activity of naturally occurring boswellic acids in specific plant extracts is enhanced by their peracetylation, preferably followed by silica gel treatment, or by peracetylation and mild oxidation to increase the ratio of 3-beta-acetyl-11-keto-beta-boswellic acid to beta-boswellic acid, 3-beta-acetyl-beta-boswellic acid and 11-keto-beta-boswellic acid. The enriched compositions compared to the commercial extracts have enhanced biological activity toward a variety of proliferative and/or inflammatory afflictions in mammalian hosts and demonstrate synergism with other phytochemicals.

Abstract: The invention is a two-stage echo canceller arrangement including a first echo cancelling stage (20) and a second echo cancelling stage (18). The first a. echo canceller adapts an input signal (x(k)) to synthesize a first estimate of an echo replica signal (@1(k)). A combiner (28) subtracts this first echo replica signal from the actual echo signal to generate a first echo cancelled signal (e1(k)). A control unit (30) monitors the change in value of the echo cancelled signal, and locks the adaptation process of the first echo canceller when the first echo cancelled signal is sufficiently less than the input signal, usually 6 dB of the input signal, to allow a near-end speech detector (23) included in the second stage to function correctly, ie to reduce the echo to a level below that at which it might be wrongly identified as near end speech. The second echo canceller, which is disposed after the first echo canceller, functions in a similar manner as the first echo canceller, and, unless inhibited by the detection of near end speech, continues to operate after the first echo canceller is locked until the echo cancelled signal produced by the second echo canceller is approximately equal to zero. <IMAGE>

Abstract: An exhaust duct is arranged vertically slidably on a vertical board saw so that it always follows the vertical movement of the sawing unit during horizontal cutting. The exhaust duct is formed by a U-shaped profile, in which an endless driven band is guided. A slot provided in the band is located in front of the saw blade (S) in every position of the sawing unit; the sawdust thrown off by the saw blade thus passes through the slot into the space enclosed by the band and is exhausted. A sealing element is fitted on the front band side just in front of the slot. The apparatus ensures a virtually 100% discharge of the chips and sawdust in the case of horizontal cutting, which is of great significance particularly in sale rooms and exhibition rooms, and contributes to humane conditions in the workshop.

Abstract: A calender wherein a permanently installed main roll cooperates with at least one exchangeable roll to provide a nip for the passage of a web of paper or the like. The end portions of the exchangeable roll are mounted in bearings which are insertable into and extractible from sockets provided in levers which are pivotably mounted in the frame of the calender. The calender has a transporting unit which is provided with grippers for the bearings and with motors which reciprocate the grippers to extract the bearings from their sockets after the levers are pivoted to positions in which the exchangeable roll is spaced apart from the main roll. The transporting unit thereupon transfers the exchangeable roll onto a mobile rack which can be transported to a station where the exchangeable roll is repaired. The same rack or a discrete second rack can deliver a refurbished exchangeable roll to the transporting unit for introduction of the bearings on the refurbished roll into the sockets on the levers in the frame of the calender before the levers are pivoted to move the refurbished roll into engagement with a running web or with the main roll. Locking devices are provided to releasably hold the bearings in their sockets, and additional locking devices are provided to releasably hold the bearings in sockets which are provided on the rack or racks. The transporting unit can constitute a robot whose grippers then constitute effectors and whose operation is automated to start a roll exchanging operation as soon as one or more sensors in the calender ascertain that the quality of the exchangeable roll is unsatisfactory for further treatment of running webs.

Abstract: In a jaw crusher, a pusher plate 3 is located between a stationary counterstop (4) (Fig. 1, not shown) on the frame and the pendulum (1) providing the crushing motion, and acting in the direction of movement of the crushing motion and, at the same time, serving as overload protection. Correct dimensioning of the pusher plates in existing jaw crushers is exceedingly difficult, with the consequence that pusher plates fail too often. With the aid of the present invention, the above- mentioned and other problems encountered in connection with pusher plates of prior art have been solved in that the pusher plate 3 consists of at least two flank plates 7 which are urged together by one or more members eg breaker bolts 5 placed under tensile load and bound to fail at a given load, and that at the point where the members are located the distance, in the cross section, between the outer margins of the flank plates 7 is largest. <IMAGE>
