Patent YU-60690-A (YU)
Inventor: DAVID ROZENWASSER
IPC: A44C11/00
Filed: 1990-03-28
Abstract: A jewelry rope chain having tightly interfitting links (a, b ...) made of wire of a given cross-section, each link having a small gap (20) formed therein slightly larger than the cross-section of said wire, so as to enable one of said links to pass through the gap of a second such link, said links being intertwined to fit tightly one against the other and form in outward appearance a double helix, the improvement being that each link comprises a non-circular geometric shape, said shape comprising a major axis defining long outer and inner diameters (Dox, Doy) and a minor axis defining shorter outer and inner diameters (Dix, Diy), said gap lying in a link section parallel to the major axis and said shorter inner diameter being just over X times greater than the cross-section of the link wire, where X is a number equal to or greater than 2, and method for making same. <IMAGE>

Title: Antibiotic FR-02A produced by Streptomyces lactamdurans - active against mouse and poultry coccidosis
Filed: 1974-10-25
Abstract: New antibiotic FR-02A (I) is produced by cultivating the microorganism Streptomyces lactamdurans (pref. S. lactamdurans NRRL 3802) under aerobic conditions in a fermentation liq. contg. a medium consisting of assimilable sources of carbohydrate, N and inorg. salts until a substantial amt. of (I) has been formed, then extracting (I) from the total fermentation or from the solids with a water-immiscible polar organic solvent. (I) can be obtd. in practically pure form by chromatography on a molecular sieve followed by chromatography on a surface-active adsorbent. (I) and its pharmaceutically innocuous, non-toxic salts are claimed. (I) is a pale-yellow solid, C59H90-96N2O21, which is soluble in lower alkyl lower alkanoates, ketones and CHCl3, slightly soluble in water, and insoluble in hexane. The ammonium salt of (I) is soluble in alcohol and CHCl3, and moderately soluble in water of pH >=7.0. (I) is active against gram-positive and -negative bacteria, and can be used against various infections in animals (esp. poultry, pigs and cattle). It is also active against mouse coccidiosis and the more important species of poultry coccidiosis. Administered subcutaneously, (I) is active against M.gallisepticum airsacculitis in poultry, and it is active orally against Bordetella bronchiseptica systemic infections in mice. (I) can also be used as a growth-promoting agent in animals such as poultry, pigs and cattle.

Abstract: Abstract of the Disclosure A thermostat including a housing assembly, a snap-acting thermally responsive actuator, and a control switch is disclosed having a switch operating arrangement coacting with the switch and the actuator.  The switch operating arrange-ment includes a lever structure hinged to the thermostat housing assembly for transmitting motion between the switch and the actuator by pivoting  about the hinge.  Heat transfer to the hinge is minimized so that movement of the lever is not impeded by the effects of heat on the hinge.  The lever struc-ture slidably engages the switch during movement about the hinge resulting in gradual wearing away of the switch engaging lever portion which compensates for normally occurring switch contact erosion.      In one embodiment of the invention the switch operat-ing arrangement includes a manually operated trip-free resetting mechanism which is constructed and arranged to apply a limited resetting force to the switch for preventing premature reclosing of the switch contacts and avoiding the possibility of damage to the switch.
