Abstract: Cooling of the rotor in the rotor chamber of a canned motor for centrifugal pumps or other fluid flow machines which serve to convey explosive liquids is ensured by installing in the rotor chamber a heat exchanger which receives liquid from the plenum chamber of the fluid flow machine or receives a fluid from another outside source.  The rotor chamber is filled with liquid which is admitted from the plenum chamber of the machine and can leak from the rotor chamber by way of a flow restricting outlet.  The outlet permits escape of gases when the machine is started but limits the leakage of liquid which fills the rotor chamber.  The outlet can admit leaking liquid into the suction chamber of the fluid flow machine.  Clogging of the outlet with solid impurities does not affect the cooling of the rotor because the outlet is necessary primarily when the machine is started, namely when it is necessary to expel gases from the rotor chamber so that the latter can be filled with liquid from the fluid flow machine.

Abstract: The various functional units which comprise a central pro- cessing unit of a computer are organized so as to enable a main arithmetic logic unit and special function units including an auxilliary arithmetic logic unit to access data registers, literal constants, and data from a memory cache. A general purpose bus closely couples the functional units to the main data paths and allows the CPU sequencer to branch on numerous conditions which may be indicated via test lines. Parity from the functional units is sent a clock cycle later than results in order that the parity path does not affect machine cycle time. The architecture allows unused microcode options to be used to check for correct CPU operation by halting CPU operation on a miscompare of two buses.

Abstract: Medical devices and methods employing semipermeable materials, such as acrylic copolymers, polyurethane isocyanate, and other biocompatible semipermeable polymers, are disclosed for use as guidance channels in regenerating nerves. The devices can be formed by tubular semipermeable conduits adapted to receive the ends of a severed or damaged nerve. The tubular conduits define lumens through which axons can regenerate to restore motor and/or sensory functions. The guidance materials are chosen such that they are capable of allowing the diffusion of nutrients and other metabolites to the regenerating nerve site while excluding fibroblasts and other scar-forming cells. In particular, tubular channels which have a smooth inner surface and longitudinally oriented trabeculae result in significantly larger regenerated nerve cables and higher numbers of regenerated myelinated axons.

Filed: 1990-07-17
Granted: 1995-04-04
Abstract: The  invention is  a system and apparatus  for screening out blood pressure measurements that are inaccur-ate because of the presence of artifact while allowing such measurements to be utilized if they are accurate despite the presence of artifact.  The apparatus is a blood pres-sure monitor having a blood pressure cuff and air pump and valve pneumatically coupled to the cuff. A pressure transducer pneumatically coupled to the cuff generates a signal representative of the air pressure in the cuff and a signal corresponding to pulses in the cuff.  A processor responds to the transducer signal and energizes the air pump to inflate the cuff, periodically energizing the valve to reduce air pressure.  The processor in response to the measurements made calculates blood pressure parameters and compares them with recorded parameters to determine whether artifact has affected the accuracy of any recorded pres-sure.
