Granted: 1990-12-11
Abstract: ABSTRACT OF THE DISCLOSURE     A molded strap fastener of a generally rectangular shape includes a first cross bar for retaining therearound a looped one end portion of a strap, a retainer poretion disposed laterally adjacent to the cross bar and frictionally engageable with the strap end portion, and a second cross bar fixedly connected to the other strap end.          The first cross bar includes a pair of diametrically opposite sharp corners and the ratainer portion has a sharp corner, these sharp corners serving as stops to retain the strap in position against accidental displacement even under heavy tensioning forces.  To provide a greater resistance to strap loosening, the first and second cross bars lie in different levels so that a rotational force is created upon the fastener when the latter is in actual use, which force growing greater the larger the tension and thus urging the retainer portion to firmly grip the strap end at its sharp corner.  This gripping is further enhanced by the retainer portion which projects beyond the bottom surface of the fastener.

Granted: 1990-11-06
Abstract: ABSTRACT          Static inverter with controlled semiconductor switches and anti-parallel diodes and with a control device for providing a current well above the rated current in the case of a short circuit in a consumer for quickly blowing a fuse in the circuit of the consumer.        Anti-parallel thyristors are connected across the inverter output.    The control device upon a short circuit takes over the control from the normal inverter control device and switches the semiconductor switches between two currents in the load circuit, of which the higher current represents the peak current limit for the semiconductor switches and the lower current lies considerably above rated current.          The control device blocks the semiconductor switches when the current limit is reached and fires at least that thyristor which allows current to pass in the direction of the actual current flow.

Title: Biologically degradable superparamagnetic materials for use in clinicalapplications
Inventor: GROMAN ERNEST V
IPC: A61K38/00
Filed: 1987-07-02
Granted: 1992-05-19
Abstract: ABSTRACT           This invention relates to materials exhibiting certain magnetic and biological properties which make them uniquely suitable for use as magnetic resonance imaging (MRI) agents to enhance MR images of animal organs and tissues. More particularly, the invention relates to the in vivo use of biologically degradable and metabolizable superparamagnetic metal oxides as MR contrast agents.  Depending on their preparation, these metal oxides are in the form of superpara-magnetic particle dispersoids or superparamagnetic fluids where the suspending medium is a physiologically-acceptable carrier, and may be uncoated or surrounded by a polymeric coating to which biological molecules can be attached.  These materials are administered to animals, including humans, by a variety of routes and the metal oxides therein collect in specific target organs to be imaged; in the case of coated particles, the biological molecules can be chosen to target specific organs or tissues.  The biodistribution of the metal oxides in target organs or tissues results in a more detailed image of such organs or tissues because the metal oxides, due to their superparamagnetic properties, exert profound effects on the hydrogen nuclei responsible for the MR image.  In addition, the dispersoids and fluids are quite stable and, in the case of the fluids, can even be subjected to autoclaving without impairing their utility.  Furthermore, the materials are biodegradable and, in the case of iron oxide compounds, can eventually be incorporated into the subject's hemoglobin, making them useful in treating anemia.  Thus, the materials are well-suited for in vivo use.
