The disclosed methods comprise the steps of providing a platelet rich suspension of platelets and blood plasma; extracting supernatant plasma from that suspension to leave between about 1 to 15 mls of plasma per unit of blood platelets with those platelets to produce a concentrated platelet button; adding 40 to 70 ml/unit of a glucose free aqueous solution to said concentrated platelet button; agitating the resultant solution to resuspend the platelets to provide a synthetic suspension of those platelets; and storing that synthetic suspension in an oxygen permeable container at about 22 DEG  C., until needed for use. Two preferred glucose free aqueous platelet storage media are disclosed which generally comprise sodium citrate, sodium chloride, potassium chloride, and either sodium phosphate or calcium chloride, but not both. The subject media also optionally comprise magnesium sulfate.

Abstract: A detuning/decoupling arrangement for a Magnetic Resonance Imaging (MRI) system RF coil arrangement (of the typing using the nuclear magnetic resonance, or NMR, phenomenon) uses switching diodes to selectively connect and disconnect portions of an RF resonant circuit in response to a DC control signal. The DC control signal selectively forward biases and reverse biases the switching diodes. The DC control current is fed to the resonant circuit along the same RF transmission line used to feed RF signals to/from the circuit. An in-line coaxial shielded RF choke connected to the RF transmission line isolates the DC control signals from the RF signals flowing on the same transmission line -- reducing the number and complexity of isolation devices required on the ends of the transmission line to separate the RF and DC signals.

Abstract: The disclosure relates to a powder flow control valve comprising a nozzle (33) formed from a material such as high density polythene having an upper frusto-conical section (33a) which converges towards the lower end of the nozzle and terminates in a cylindrical section (33b). The nozzle is encircled by a plenum chamber (24) to which sources of vacuum and air pressure are selectively connectable through a pneumatic control system (14). When vacuum is connected to the plenum chamber, the resulting pressure drop across the wall of the porous nozzle causes powder flowing through the nozzle to consolidate in the nozzle and terminate the flow. When air pressure is applied to the plenum chamber, the resulting pressure rise across the boundary surface accelerates powder flow through the nozzle. The control means is arranged to establish air pressure in the plenum chamber to initiate opening of the valve and flow through the valve and, after a pre-determined time, to terminate the air pressure supply and allow powder to flow under gravity through the nozzle before flow is terminated when a pre-determined quantity of powder has been delivered by the nozzle by applying vacuum to the plenum chamber.
