Abstract: An electro-acoustic transducer of novel structure suitable for automatic assembly is made by arranging with its wall upwards a generally cup-shaped rear cover 20 having a cylindrical wall out-turned at its upper end and extending from the rim of a base divided along a chord 60 into a major segment 61 for receiving an electromagnetic driving unit 30, 34 and a terminal receiving minor segment 62 at a higher vertical level than the major segment 61. The major segment 61 has on its inner face fixing lands 40, 41 disposed symmetrically with respect to a diameter normal to said chord 60 offset away from the minor segment 62 and extending inwards from the side wall. Each fixing land 40, 41 is formed to define a fixing location 64 and having on its face presented to the minor segment an upstanding locator wall 66; 
<??>A yoke and coil sub-assembly lowered into the rear cover is defined by a cruciform yoke plate of magnetisable material having a magnet 50 at its centre with one pair of upturned opposite arms directed along the diameter normal to said chord 60 to said pair of arms defining pole pieces and carrying coils 30, 31 and with the other pair of upturned opposite arms 32, 33 parallel to the said chord 60 and formed with outturned fixing ears 52 that settle directly on said lands 40, 41 behind said locator walls 66 with through-holes 52 therein aligning with said fixing locations 64 of said lands; 
<??>Onto the yoke and coil sub-assembly is placed downwardly an armature 34 formed with depending bearing means that settle on the magnet 50 and permit the armature 34 to rock thereon and a pair of torsion arms extending towards the lands 40, 41 and terminating in fixing ears 35, 36 that settle behind the locator wall 66 on the fixing ears 51 of the coil sub-assembly with through-holes 52 aligning with said fixing locations 64 of said lands. The armature has secured thereto an upstanding connecting rod 34a; 
<??>The armature 34 is mechanically fixed from above the rear cover in tight contact with the yoke plate and the yoke plate is fixed in tight contact with the lands 40, 41 so that the armature is supported for vibration in said rear cover 20. Connector terminals 45 are introduced through said minor segment 62 and electrically connected to the coils. A dished diaphragm 23 is placed downwards onto the rear cover so that its rim 25 settles on the outturned end of the cylindrical wall and the connecting rod 34a projects through a throughhole in said diaphragm. Then the connecting rod 34a is adhered to the diaphragm 23; and a front cover 10 is assembled to the rear cover 20.

Abstract: Athletic shoe sole with cleats having exchangeble grip elements that are snap-locked to a mounting stud. The grip element can easily be inserted and removed again, without impairment of shoe sole stability or danger of damage thereto, by the provision of interactive engagement formations, comprised of a minimum of one raised area 16, 17, 26 and a complementary recessed area 19, 28, that have at least one inclined surface that produces a relative axial shifting between the gripping element and mounting stud when the gripping element is rotated about its longitudinal axis. Preferably, the raised areas 16, 17, 26 are arranged such that, in the snap-locked condition, they do not have operative contact with the recessed areas 19, 28, but can be brought into operative contact by rotating grip element 11 around its longitudinal axis x, and thereafter the grip element 11 can be pressed out over the catch point of the snap-lock device or snap-lock devices 8, 12 to release the grip element from the mounting stud.

Abstract: Process for the treatment of aqueous sweet juice containing a mixture of saccharides containing an aldehyde functional group, especially fructose, and saccharides containing a ketone functional group, especially glucose, with a view to separating and selecting the saccharides containing a ketone functional group. It consists (a) in making up a hydroorganic medium by mixing the sweet juice with a ketonic compound containing active methylene, a calcium-based catalyst and preferably ethanol, (b) in stirring the medium until the formation of furane-based polyol by condensation of the ketonic compound and the saccharides containing an aldehyde functional group, and (c) in allowing the furane-based polyol to precipitate and separating it off by a physical route from the liquid medium; the latter is completely freed from the saccharides containing an aldehyde functional group. The process of the invention makes it possible, in particular, to prepare pure fructose syrups.

Abstract: The invention provides a mold for the continuous casting of steel strip. The mold is arranged with a mold cavity having a longitudinal axis parallel to the casting direction. The width of the cavity in its upstream area is sufficient to provide at least the required minimum spacing between the pouring tube and the walls of the mold. The mold comprises side- and end-walls arranged respectively to define a cavity having three portions, the first being of substantially the same parallelepipedal cross-section as the strip being cast; the second being a flared area in the upper central area of the mold to accommoate a pouring tube, wherein the side-walls are tapered inwardly from the upper part of the mold to a lower point at which the cross-section of the mold approximates the size and shape of the strip being cast; and the third being a strand shell formation initialization zone in the flared area having walls extending in substantial alignment with the longitudinal axis of the mold from the surface level of the molten bath at which the strand shell starts to form, to a point where the strand shell is sufficiently thick to withstand tapering inwardly without wrinkling or rupturing.

Inventor: BRUCKNER RAIMUND
IPC: B22D41/14
Filed: 1989-07-31
Abstract: The present invention is drawn to a regulating device of a metallurgical vessel for regulating the flow of molten metal from the vessel. The device includes a fixed refractory part defining a first cylindrical peripheral surface of the device and a movable refractory part that is rotatable and/or slidable relative to the fixed refractory part and defines a second cylindrical peripheral surface sealingly engaged with the first cylindrical peripheral surface. An actuating device is connected to the movable refractory part for rotating and/or sliding the movable refractory part relative to the fixed refractory part. The cylindrical peripheral surfaces of the refractory parts are spaced apart from one another so as to define an annular gap therebetween. In order to ensure that during operation the refractory parts can be moved relative to one another by the actuating device while preventing the penetration of molten metal into the annular gap, each of the refractory parts has a coefficient of thermal expansion which, when the device is subjected to a high temperature corresponding to the melting temperature of a molten metal, causes a clearance fit to be established between the peripheral surfaces that is effective to prevent molten metal having a melting point at the same predetermined high temperature from penetrating between the peripheral sealing surfaces while allowing the movable refractory part to be moved relative to the fixed refractory part.

Inventor: AGRAWAL SUDHIR
IPC: C40B40/06
Filed: 1990-04-05
Abstract: A process of producing synthetic oligonucleotides on a small or large scale using H-phosphonate nucleoside monomers is described. The process can be used to synthesize oligonucleotides of any length, including oligodeoxyribonucleotides and oligoribonucleotides. The process results in a coupling efficiency of greater than 97% and consumes only two to three equivalents of monomer to activator per coupling reaction. In addition, the process does not require a separate capping step and capping reagent because the activating reagent serves a self-capping function thereby preventing elongation of failed sequences. The H-phosphonate linkages of the fully synthesized oligonucleotide can be oxidized with a variety of reagents to obtain either phosphate diester or other types of modified oligonucleotides.
