Abstract: Řešení se týká zařízení pro vrstvení a manipulaci
dlouhých předmětů, zejména pak
předmětů o nestejné délce profilu a hmotnosti,
které mohou být uloženy jen ve svých
krajních bodech a nesmějí se navzájem dotýkat.
Podstata spočívá v tom, že toto zařízení
obsahuje dva nebo více stahovacích rámů,
z nichž každý je tvořen sloupky, které jsou
opatřeny háky a profily pro vrstvení a mezi
nimiž je uchycen příčník s lůžky pro manipulované
předměty. Stahovací rámy mohou
být ve stavebnicové konstrukci dále podle
potřeby kombinovány s pomocnými typizovanými
prvky — podložkami a prokládacími
nosníky. Stohovací rámy nebo celá
stavebnicová konstrukce může být přechodně
uložena na tříosém vozíku.
Hlavní výhodou řešení je to, že výše specifikované
zařízení je schopno proporcionálně
zajistit všechny funkce, požadované při
vrstvení a manipulaci dlouhých předmětů.
Přitom se jedná o jednoduché zařízení, které
je vzhledem ke své stavebnicové konstrukci
použitelné pro předměty různých délek,
profilů a hmotností.

Abstract: A visceral anchor and method for visceral wall mobilization is disclosed. The visceral anchor includes an elongated cross bar to which a suture is attached at a location substantially in the center of the cross bar. The cross bar further includes a helical spring sheath which jackets a rigid rod, the sheath extending beyond the ends of the rod to form flexible ends. An alternative embodiment includes a second suture attached to one of the ends of the cross bar. The sutures are used for orienting the anchor during insertion into and removal from a hollow viscus. The method of visceral wall mobilization includes providing a tract through the skin into a hollow intra-abdominal viscus and inserting the anchor into the viscus lumen. The sutures extend through the tract and the unattached ends remain on the outside of the body. The center suture is pulled to orient the anchor for mobilization of the visceral wall. The end suture is pulled to orient the anchor for removal.

Abstract: A device for the swiveling movement of a sheet is described. A stationary bearing part supports an articulated part in a swivelable manner. The articulated part supports the sheet and is movable about a substantially horizontal swivel axis. The sheet is accordingly movable between a lowered position and a raised position, the direction of this movement being determined by a vertical swiveling plane. Energy accumulators, e.g., pneumatic springs, serve as auxiliary lifting means for raising the sheet. These energy accumulators have two connection ends which are loaded in opposite directions and determine the effective direction of force of the energy accumulator. For the purpose of an advantageous arrangement of the device which economizes on space, it is proposed that the energy accumulator be arranged with its effective direction of force substantially transverse to the swiveling plane of the sheet. The two connection ends of the energy accumulator are constructed as three-dimensionally acting rolling joints.

Title: Antibiotic a-28086 and process for production thereof
IPC: A23K20/195
Filed: 1975-06-05
Abstract: The novel antibiotic A-28086 complex containing the factors A, B and D is produced by culturing Streptomyces aureofaciens NRRL 5758 or Streptomyces aureofaciens NRRL 8092 in a culture medium, which contains assimilable sources for carbohydrate, nitrogen and inorganic salts, in submerged aerobic fermentation conditions until these organisms have produced a significant amount of antibiotic activity in the culture medium. The antibiotic is then separated off from the culture medium. The novel antibiotic can be dissociated into the factors A, B and D. These can be converted into the corresponding physiologically tolerated salts. The novel antibiotic can likewise be converted into C2-C6-acyl esters. The novel antibiotic A-28086 complex, the factors A, B and D, the physiologically tolerated salts thereof and also C2-C6-acyl esters thereof are used to increase the feed intake of ruminants. They can additionally be used for the prevention or treatment of coccidiosis in poultry.

Filed: 1990-10-25
Abstract: The present invention relates to the technical field of control and interfacing devices for optical fiber lines and more particularly to an adapter (6, 8, 11, 13) for amplified optical lines. Said adapter comprises an optical-to-electric converter module (18) and an adjustment module for a laser (22) different from that for the line apparatus (2), on the transmitting side (3), both modules being optically connected both at the input and at the output to the respective apparatuses (2, 15) of the line transmission (3, 17) and reception (16, 4), the corresponding optical line amplifiers (7, 12, 14, 9) being interposed therebetween; the first converter module on the transmitting side exhibits an input consisting of a photodetector (18) for carrying out the optical-to-electric conversion of the incoming signal, connected to an electrical amplifier (19) for the automatic control of the voltage level, designed to control the variations of the optical input signal, which amplifier generates at the output an electrical signal which enters the adjustment module (20) consisting of a piloting circuit for a laser (22) different from the line one, allowing the selection of the wavelength of the same and determining at the output therefrom an optical signal adjusted in accordance with the parametric requirements of the optical line amplifier to which the adapter (6) is connected, as well as controlled according to the temperature variations in time of the laser wavelength; the piloting circuit (20) exhibits at the input thereof an analog circuitry (21) for the connection with the optical service channels; on the contrary, on the receiving side the converter module, still connected to the adjustment module, although clear of control circuits for the laser wavelength depending upon temperature, exhibits the photodetector (24) coupled in alternating current through a condenser (20) to the electrical automatic voltage livel-controlling amplifier (26) connected in a circuit to the adjustment module (27) and also exhibits a second coupling (29) in alternating current, on a different circuit branch, to the connection circuitry (32) for the optical service channels through an electrical amplifier (31) ahead of which a low-frequency filter (30) is provided; in this way the adapter for optical lines appears as an optical coupling adapter both at the input and at the output and is independent of the optical line parameters, but it enables a universal connection between any type of optical transmitting-receiving apparatus and any optical line amplifier.
