Abstract: Antibacterially active penem compounds and salts of the formula ##STR1## wherein R is hydrogen or an esterifying group, R.sup.2 is hydrogen, hydroxy, or protected hydroxy, and R.sup.1 is phenyl, naphthyl, thienyl, pyridyl, quinolyl, or isoquinolyl, or such a group which is mono-, di-, or tri-substituted; methods for making such compounds or salts; and antibacterial pharmaceutical preparations containing the compounds or salts.

Abstract: An orthopaedic bone cutting jig and alignment frame for facilitating a series of controlled, precise bone cuts to fit selected prosthetic knees which promote bone imgrowth and do not rely upon cement for fixation.

Abstract: A mechanism for drying a traveling web such as employing a steam heated dryer drum in a papermaking machine with the drum being supported on end bearings in journals in a frame and a rigid condensate removal tube extending through one of the journals with its inner end adjacent the inner surface of the drum and the drum having a rotary steam seal through which the tube passes with a pivotal mount for the rigid tube and a micrometer adjustment which adjusts the pivotal position of the tube so that the inner end of the tube being cantileverly supported can be adjusted accurately relative to the inner surface of the drum.

Abstract: A steam heated dryer drum for use in a papermaking machine with the drum including a cylindrical rotary hollow drum shell and a structure for removing condensate from the steam from the shell including a conduit leading from inside to outside the shell and an improved structure for receiving the condensate with a siphon tip having a hollow chamber within and an opening facing the inner surface of the dryer shell and closely spaced thereto and a flange at the lead end of the siphon tip with an inclined ram surface and a wall across the center of the chamber in engagement with the inner surface of the shell.

Abstract: A method and mechanism for dewatering a web in a paper making machine having press means, a first thermal dryer section having a long continuous support looped belt carrying the web along a first drying run with rolls and suction zones beneath the web and a hot air generating means for directing a flow of air onto the web in the first thermal run with the web being received substantially 40% bone dry at the beginning of the first thermal run and being delivered substantially 50% bone dry at the end of the run onto a heated drum dryer section.

Abstract: Sugar extraction efficency from sugar-containing plant tissue, such as sugarbeet cossettes or the like, is increased by contacting the sugar-containing plant tissue near the juice end of a diffusion process with diffusion water in the presence of an effective amount of carbon dioxide.

Abstract: Crude phenol is recovered from CHP reaction products by continuously feeding to a main column separating in its uppermost section phenol from crude acetone, this fraction being removed overhead, and in the lower section crude phenol from higher boilers, including acetophenone and carbinol, the crude phenol being removed as a sidestream fraction from the main column at a point in the column above the feed-point wherein the total concentration of acetophenone plus carbinol is less than 1,000 ppm and the higher boiling compounds being removed as a base fraction.

Abstract: The present invention relates to a method of and apparatus for the radionuclide imaging of the whole body of a patient using an unmodified scintillation camera which permits a patient to be continuously moved under or over the stationary camera face along one axis at a time, parallel passes being made to increase the dimension of the other axis. The system includes a unique electrical circuit which makes it possible to digitally generate new matrix coordinates by summing the coordinates of a first fixed reference frame and the coordinates of a second moving reference frame.
