摘要： A surgical cutting instrument, particularly useful for ophthalmic surgery, includes an elongate probe formed of an outer tubular member having an aperture in the distal end thereof and an inner cutting member having a peripheral cutting edge at the distal end thereof and an elongate body with an opening running therealong and carrying a piston disposed in a chamber of a hub through which the inner cutting member extends and which communicates with a source of suction, a drive unit for reciprocating the inner cutting member relative to the outer member, the opening along the inner cutting member forming an increased cross sectional flow area for cut substances being withdrawn by suction and the relative reciprocation of the inner and outer members coupled with increasing and decreasing pressure from the piston agitating the cut substances to prevent clogging of the probe. A finger-operated valve is formed of an elastic tubing stretched over the closed end of a rigid tube communicating with the chamber of the hub, the rigid tube having an opening in a side wall adjacent the closed end, which opening is normally sealed by the elastic tubing and can be opened by applying a force to the tubing at a position opposite the opening.

摘要： An Auto-Pilot for steering a craft automatically in water or air, and including a flux gate arrangement mounted to the craft in a predetermined horizontal directional orientation, and a resolver having a first section with coils energized by signals from the flux gate to produce a magnetic field dependent upon the heading of the craft relative to the earth''s magnetic field, and a second section having a coil which produces an output signal representing the position of that coil relative to the field produced by the first mentioned coils. One of the resolver sections can be rotated relative to the other section to any selected setting representing a desired course which the craft is to follow, and the output of the resolver is then utilized to automatically steer the craft toward that course. In a second mode of operation the output from the resolver may be disconnected from the steering mechanism and be utilized in a non-steering manner to automatically return the rotatable section of the resolver to a position corresponding to the field which is generated in the resolver by the flux gate, and thereby cause the rotatable section of the resolver to follow the earth''s magnetic field and function as a compass repeater.
