Abstract: A intravenous infusion device which includes a bag of an impervious flexible material which is divided into two compartments by a central partition of an impervious flexible material. A first compartment is filled with an infusion liquid and contains an outlet provided with a connection to a flexible hose and an infusion needle. The second compartment is empty and has an inlet provided with a connector to an inflation device such as a hand-operated balloon. This second compartment can be inflated to exert a pressure on the first compartment in order to cause the infusion liquid to be conveyed into the patient's vein at the required rate of flow. The infusion device can be used in all cases where the bag cannot be suspended above the patient as for instance on the battlefield or after an accident. It is likewise suitable in all cases where an increased rate of infusion is required.

Abstract: The invention relates to an emulator system which allows a disk drive to transparently emulate a tape drive. The system converts sequential format tape records into block format disk records and visa-versa. Identification and conversion information for each of the data records are stored in directory located on the outermost sectors of the disk. Within each directory are a plurality of entries each containing four fields: TAPE RECORD NUMBER (TRN); DISK START ADDRESS (DSA); WORD COUNT (WC); and FLAG. These fields contain all of the necessary information required to map a tape formatted data record to a disk and thereafter retrieve the data record from the disk and convert it back to tape format.
