Abstract: This invention relates to a machine and method for setting up and completing certain manipulative operations of the panels of a collapsed basket style container. 
<??>A collapsed carton (c) is withdrawn by a reciprocable feeder (10) assisted by suction means from a hopper (1) and deposited in the path of movement of movable suction means (4) which engages one side wall of the carton and drives the carton towards fixed suction means (3) which in turn engages the opposite side wall of the carton. Thereafter pivotal movement of the movable suction means (4) in a direction away from the fixed suction means (3) draws the carton side walls apart and initiates setting up of the carton. 
<??>The machine is particularly well suited for use by a packager for setting up and glueing a collapsed basket style carton of the type which is intended for heavy duty usage and which will not need to be collapsed after it is set up.

Abstract: Non-phosphorylated peptides and phosphopeptides useful as alimentary products or medicaments are produced by proteolytic enzyme hydrolysis of a casein-based material. Membrane ultrafiltration is used to separate phosphopeptides which are retained by the membrane in a retentate from the non-phosphorylated peptides which pass through the membrane in an ultrafiltrate. The phosphopeptides in the retentate are disaggregated and are subjected to further membrane ultrafiltration where the phosphopeptides pass through the membrane and are separated from the enzyme. The non-phosphorylated peptides have nutritive value and can be used to form compositions for providing nutrition. The phosphopeptides form salts, which have dietetic uses, with macroelements such as calcium and/or magnesium and/or oligoelements such as iron and zinc.

Abstract: A two-band multimode microwave source for an antenna of a low-elevation-tracking radar comprises a higher-frequency section nested in a lower-frequency section, the two sections having E-planes perpendicular to each other. The lower-frequency section includes two outer pairs of waveguides separated by a block which convergingly projects beyond their output ends and is bisected by the E-plane of that section. The higher-frequency section includes two inner pairs of waveguides disposed within that block and separated by an obstruction lying in the last-mentioned E-plane. The higher-frequency wave emitted by the inner waveguides is made planar by a lens disposed at n output aperture of the structure which is transparent to the lower-frequency wave. In a Cassegrain-type radar antenna the lower-frequency wave emitted by the source is returned by a semitransparent intermediate reflector toward a main reflector provided with a grid which rotates its plane of polarization to let it pass out through the intermediate reflector along with the higher-frequency wave which, passing unattenuated through the intermediate reflector, is returned by a solid outlying reflector to the main reflector.

Abstract: Bulk cargo which is sensitive to condensate is confined in the cargo area of a seagoing or other vessel in such a way that it comes into direct contact with the walls surrounding the cargo area and is also in contact with moisture-laden air filling the remainder of such area. In order to prevent condensation of moisture on the walls surrounding the cargo area, the temperature of the walls as well as the temperature of air in the cargo area is maintained at a value such that the moisture cannot condense on the walls. This can be achieved by heating the confined air and/or the walls and/or by reducing the moisture content of confined air and/or by a combination of such undertakings.
