Abstract: A synchronization circuit for a system in which digital coded data is received by an exchange from a transmitting station in time division multiplex form and is transmitted in time division multiplex form. In such a system, the incoming data is received at a clock rate dependent on the clock of the transmitting station and is stored in a memory at that rate. Read out from the memory is at the exchange rate. Since only one operation in the memory, either read or write, can occur at a time, control must be imposed to separate in time the reading and writing operations. To provide this separation, a time shift equal in duration to one time slot is introduced to delay the later-started of two operations.

Abstract: The present invention provides a method for treatment or prophylaxis of certain inflammatory diseases of the mammalian large intestine which comprises administrating a cytoprotective prostaglandin to a mammal who suffers from or is particularly susceptible to said inflammatory diseases of the large intestine. Cytoprotective prostaglandins refer to those prostaglandin-type compounds which are useful in reducing the incidence of NOSAC-induced lesions in the intestinal wall of the rat. "NOSAC" is an abbreviation for "nonsteroidal antiinflammatory compound.

Abstract: The present invention provides a method for treatment of Crohn's disease, inflammatory bowel disease, infectious enteritis, sprue, and intestinal inflammatory disease secondary to radiation exposure or an intestinally-manifested allergic response to foodstuffs which comprises administrating a cytoprotective prostaglandin to a human who suffers from one of said diseases. Cytoprotective prostaglandins refer to those prostaglandin-type compounds which are useful in reducing the incidence of NOSAC-induced lesions in the intestinal wall of the rat. "NOSAC" is an abbreviation for "non-steroidal antiinflammatory compound.

Abstract: Synchronization control circuit for a time divisional data transmitting and receiving system. Data is received at an exchange at a clock rate determined by the transmitting station and is stored in memory at that rate. Read-out of data from the memory is based on the internal clock rate of the exchange. Since only one operation -- read or write -- can occur on a memory at any one time and the operations are controlled at rates which may be out of synchronism with one another, conflicts may occur. To prevent such conflicts, a time shift of predetermined duration is inserted between operations when the out-of-synchronism interval is less than a predetermined time interval.

Abstract: There is disclosed concomitant systemic administration of certain prostaglandins of the PGE-type and PGA-type, for example, 16,16-dimethyl-PGE.sub.2 of 16,16-dimethyl-PGA.sub.2, and a prostaglandin synthetase inhibitor, for example, indomethacin, aspirin, or phenylbutazone, to mammals, including humans. Thereby the undesirable gastrointestinal effects of the synthetase inhibitor are reduced.

Abstract: An electrical control device for an inflating valve for containers for compressed, liquefied or dissolved gas with a cylindrical plug of fusible non-conductive material in which is embedded a helically wound electrical resistor formed as a cylinder having an axis substantially parallel to the plug axis and adapted to be connected to an electrical source. The plug is maintained in the inflating valve by a sleeve provided with a cavity and radial openings. Upon closing of the electrical circuit, the resistor heats and melts the plug, the central portion of which escapes towards the upper portion of the cavity opening to open a passage between the port connected to the container and the discharge port of a rotatable fitting surrounding the inflating head. The present invention can be used advantageously to control the discharge of a gas contained in a container in a pneumatic capacity and especially an inflatable lifeboat.
