Abstract: An apparatus and method for the delivery and removal of a biocompatible liquid to and from the lungs of a mammal, comprising an ice water container adapted for containing ice water; a biocompatible liquid tank disposed within the ice water container, with the tank adapted for containing a biocompatible liquid; and a biocompatible liquid infusion reservoir disposed within the biocompatible liquid tank. The apparatus also comprises a pump assembly and tube assembly that are in operable connection to the ice water container, biocompatible liquid tank and biocompatible liquid reservoir so as to provide a volume of biocompatible liquid to and from the lungs of a mammal, while breaths of oxygen are supplied using a manually operated air bag.

Abstract: A code detector for detecting the presence or absence of particular binary digital signalling codes in the digital bit stream from extension telephones of a digital PABX telephone system. The detector is connected to a telephone being monitored and receives digital data from the telephone, which data may be random speech data or a signalling code. The detector consists essentially of a ROM which uses each of the data bits arriving in serial form as the least significant bits of the address for a micro-program stored in the ROM which provides the other address bits, thus causing the program to be stepped through a sequence of addresses which depend upon the sequence of the incoming data bits. For a program to end up at a specified address the ROM must receive the code which is unique in causing the program to arrive at that address. The detector then outputs a code representative of the detected code.

Abstract: A synchronous digital data switching apparatus in the form of a PABX telephone system is disclosed. The extension telephones of the apparatus are fully digital and transmit synchronous digital data to the switch. The switch includes a detector for scanning the inlets and remains connected to each inlet until the state of that inlet or a code is detected. Consequently the size of the switch is limited by the speed of available technology as all inlets must be examined within the minimum signalling period of any inlet. The telephones continually transmit digital data relevant to their state and also transmit digital codes during signalling. The apparatus is processor controlled and a switch memory for setting up connections between any inlet and any one or more outlets is time shared between the switch and processor.
