Abstract: A segment of a bacteriophage encoding for a polysaccharide depolymerase which has been cloned and expressed in Escherichia coli is described. In particular, bacteriophage ERA103 was found to consist of five EcoRI fragments labeled: A, 7.5-kb; B, 5.0-kb; C, 2.7-kb; D, 2.1-kb and E, 1.8-kb. Fragment B encodes for the depolymerase and was cloned into the positive-selection vector pOP203(A2+), pBR322 and the expression vector pKK223-3. The depolymerase is applied to rosaceous plants to prevent Fireblight caused by Erwinia amylovora by depolymerizing a polysaccharide produced by this bacteria.

Abstract: An improved, more economical mold (12) for use in continuously casting metals or alloys comprises a mold tube (40) and a pair of flanges, one flange peripherally disposed of and in abutting, liquid sealing relation with each end of the tube. Such sealing relation is preferably provided by a continuous knife-edged protrusion (66) formed in and disposed peripherally of each flange and adapted to sealingly cooperate with a continuous shallow groove formed in and disposed peripherally of each end of the tube. Cooling means including a jacket and a baffle surround the tube between the flanges, and the baffle (70) further defines a channel immediately circumjacent a substantial portion of the outer surface of the tube for directing a flow of cooling liquid about the tube in direct contact with such surface. Removable assembly means releasably interconnect the two flanges (50, 60) and the baffle disposed therebetween in such a way as to clamp each of the flanges to its respective end of the mold tube, thus effecting both liquid-tight seals as well as creating a unitary assembly. Accordingly, an efficient method for repairing the mold via quick dissassembly, tube replacement and quick reassembly is also provided.

Abstract: The coupler contains 2 parallel strip-guides (3,4) and a pn-junction allowing injection of charge carriers. The guides are separated by a gap (a) of which the refractive index is modified by the charge injection. On an n-InP substrate (1) p-type diffusions are formed (12) which extend to the inner edges of the guides (3,4) or even further. The strip guides (3,4) are formed by first etching the substrate and subsequently depositing epitaxially a layer of InGaAsP (7) with a lattice constant adapted to the host-crystal. A further area (10) may also be formed in this way.  This layer is then coated with a mantle-layer (6) of InP, which is followed by a contact layer (8). A p-type diffusion is formed int he mantle witha width which extends to the inner edges of the strip-guides (3,4) and in the other direction runs parallel with the guides (11). A mask of SiO2 (9) is applied to the contact layer (8) to restrict the size of the contact area. A voltage is applied between the contacts 5 and 2 to cause injection via the pn-junction at the edge of the area (11).  A strip (10) formed between the 2 guides (3,4) may also be used as an additional wave-guide.

Abstract: A first stage in mfr. of isocyanates involves reaction between a soln. or suspension of a primary amine (or its salt) and phosgene soln. The latter soln. is directed axially into a housing to impinge on the transverse disc projecting from a rotor shaft and then move radially outwards over the disc surface. During this movement to phosgene soln. contacts the amine fluid which, after entering a cap surrounding the phosgene inlet pipe, is sprayed via multiple apertures in the housing end wall, and via a stator disc, to impinge on the rotor disc as streams parallel to the phosgene but spaced therefrom in a regular ring. Both stator and rotor have concentric rings of projecting pins to promote stirring. A number of rotor/stator disc assemblies may follow alone the drive shaft.

Abstract: An inexpensive square baler is provided with an arcuate baling chamber (54) and a plurality of spaced apart plunger elements (70) shiftable about an kidney-shaped, closed loop path of travel (84). The baling chamber (54) is partially defined by a horizontal table and a wrapper which have a number of common openings each corresponding to one of the elements. During a return stroke portion of the plunger elements (70), the latter retract out of the baling chamber and re-enter the chamber between the openings in the table to enable the chamber to accumulate significant quantities of crop materials without interference with the plunger elements during their return stroke portion thereof. A header of the baler (25) includes an auger mechanism (30) having members which urge the crop materials directly through an inlet of the baling chamber without the need for intermediate conveying apparatus, and the members interleave with the plunger elements during the time that the latter pick up crop materials from the table in order to substantially close the inlet of the baling chamber and reduce the amount of crop materials that would otherwise be discharged in a reverse direction through the same.
