Title: Process for the preparation of esters of 4-(2,3-epoxypropoxy)phenylacetic acid and 4-(2-hydroxy-3-isopropylamino-propoxy)phenylacetic acid and/or atenolol in stereospecific form
Inventor: PHILLIPS GARETH THOMAS
IPC: C07C233/00
Filed: 1987-07-28
Abstract: S-(-)-atenolol (4-(2-hydroxy-3-isopropylaminopropoxy)phenyl acetamide) is obtained by a process including the step of stereo-specific epoxidation by an ester of 4-allyloxyphenylacetic acid using a micro-organism capable of stereo-selective epoxidation, e.g. Pseudomonas oleovorans, to produce the corresponding ester of 4-(2,3-epoxypropoxy)phenylacetic acid which is predominantly in S configuration. Pseudomonas oleovorans ATCC 29347 produces at least about 90% of the epoxypropoxy compound in S configuration. The resulting epoxypropoxy compound can be converted into atenolol, maintaining the high proportion of S configuration, by reacting the epoxypropoxy compound with isopropylamine and converting the ester group to an amide group by reaction with ammonia.

Title: Arrangement for the helical winding of smooth,non-sinuous tape on pipes of circular cross-section
Inventor: DENNER P
IPC: B21C37/26
Filed: 1987-08-13
Abstract: The invention relates to a device for the helical taping of circular tubes (4) with smooth, uncorrugated tape (8), which is drawn off from a tape roll (7) by the rotating tube (4) and deformed by a rolling process immediately before it is applied to the tube (4). The rolling process is brought about by a rolling ring (12), driven synchronously with the tube (4) by the tube's (4) rotary drive unit and surrounding the tube (4), and a frictionally driven rolling plate (13), whose circumferential surface can be adjusted about an axis lying at a transverse angle to the tube's longitudinal axis (4a) and fed in to the rolling ring (12). The rolling ring (12) and the rolling plate (13) with its adjusting device are located on a rotary table (10) which, according to the particular inclination of the tape (8) being wound can be rotated about an axis (17) intersecting the longitudinal axis (4a) of the tube at right angles as an extension of the lead point (16) of the tape (8) onto the tube (4). Also located on the rotary table (10) is a slotting tool (20) whose cutting edge (20a) engages on the tube (4) roughly 90<o> in front of the lead point (16) of the tape (8) onto the tube (4). <IMAGE>

Title: Method and apparatus for making hellically wound extrudate particles
Inventor: BAMBRICK WILLIAM EDWARD
IPC: B29C33/44
Filed: 1988-05-20
Abstract: An extrusion die useful for forming helical extrudate particles of inorganic oxide materials, is made by molding the die around pins (34) having helical outer surface (35) to form extrusion holes in the die. Helical walls of the extrusion holes are formed by the helical shape of the pins (34). When the molded die is formed, the helical pins (34) are unscrewed out of the helical holes in the die to avoid damage to the die.

Title: Method and apparatus for the continuous damping of grain and use of the damping machine
Inventor: MUELLER ROMAN
IPC: B02B1/06
Filed: 1993-07-30
Abstract: PCT No. PCT/CH93/00189 Sec. 371 Date Jun. 22, 1994 Sec. 102(e) Date Jun. 22, 1994 PCT Filed Jul. 27, 1993 PCT Pub. No. WO94/03274 PCT Pub. Date Feb. 17, 1994The invention proposes the damping of grain, for example, by creating a rotating layer (20) in a damping chamber (2) with the help of acceleration rotors (3). For this, the cross-section of the rotation chamber is designed to form an outer boundary around two or, preferably, three acceleration rotors (3, 3', 3''). In this way, the rotating layer is forced into an eccentric and spiralling motion within the damping chamber (2). Damping is carried out in a very gentle manner, so that there occurs hardly any abrasion and no grain damage. Additional advantages include a longer and controllable reaction period during damping, optimized preparation for milling and a shorter, controllable tempering period.
