Abstract: NUCLEAR STEAM GENERATOR            Abstract of the Disclosure A nuclear steam generator has a blowdown pump arranged to pump water from the blowdown lines through a filter for return to the steam generator.  The piping is arranged so that the same pump may operate to reverse the direction of pumping through the blowdown line, whereby reverse circulation may be established during wet lay up of the steam generator.  A blower is arranged to withdraw nitrogen from an upper elevation in the steam generator and injected into the blowdown line in combination with the pumped reverse circulation during wet lay up.

Abstract: LIGHT PIPE FOR ACCURATE ERASURE    OF PHOTOCONDUCTOR CHARGE          Abstract of the Disclosure Erase apparatus for use in an electrophotographic copier machine where an array of light-emitting diodes (LEDs) are placed adjacent one end of a light channel with the other end adjacent a moving photo-receptive surface.  The channel allows light rays to pass freely from LED to LED but contains the rays in a direction parallel to the direction of photoreceptor movement.  The channel may be comprised of sides with reflective surfaces normal to the photoreceptive surface or may be a solid plastic sheet through which the rays pass.  In the latter embodiment, rays are internally reflected from the surfaces of the plastic sheet.

Abstract: 1                    PHD. 79-011. ABSTRACT:         During the fabrication of integrated cir-cuits testing is necessary in order to enable faults to be located.  For this purpose it is known to connect test points to specific points of the circuit, which dur-ing fabrication are accessible with a suitable designed scanner.  Owing to the location of the test points smaller blocks are formed in comparison with the complete circuit arrangement.  According to the invention transistor switched are included to provide isolation of selected in-put and output transistor blocks to allow separate testing as well as testing in combination.

Granted: 1982-12-07
Abstract: ABSTRACT There is provided a method of taking a sample of gas exhaled by a subject and passing the sample through a duct from an inlet to an outlet thereof.  The duct is initially closed.  The pressure of exhaled gas in the inlet of the duct as created by the subject is monitored, and, provided that that pressure is maintained above a predetermined threshold pressure for a predetermined period, the duct is opened at the end of that period to allow the exhaled gas to flow through the duct.  An apparatus for implementing the method is also provided, which is suitable for sampling alcohol-containing exhaled gas, which can then have its alcohol content analyzed.

Title: Hydraulically operated actuator
Inventor: BURKHARDT JOSEPH A
IPC: E21B34/00

Abstract: APPLICATION FOR UNITED STATES PATENT     HYDRAULICALLY OPERATED ACTUATOR            ABSTRACT OF THE DISCLOSURE           A hydraulically operated actuator employs multiple metal-to-metal static seals to isolate the hy-draulic fluid  and to isolate the actuator from surrounding contaminating (ambient) fluids.  A housing contains at least two linearly spaced apart chambers.  A piston recip-rocates from a retracted position to an extended position (power stroke) and from the extended position to the re-tracted position (return stroke) in one of the chambers (hydraulic chamber).  The hydraulic chamber is separated by the piston into two sections, one of which contains high pressure hydraulic fluid and the other of which con-tains low pressure hydraulic fluid.  A first static metal seal ring unit is designed to seal first at the comple-tion of the power stroke of the piston to isolate the low pressure hydraulic fluid section from external con-taminating fluids which may be at a higher pressure.  A second static metal seal ring unit is designed to seal at the completion of the return stroke of the piston also to isolate the low pressure section from external contami-nating fluids.  Power for the return stroke is primarily supplied by springs, with biasing pressure from the ex-ternal environment providing a lesser contribution.  A third static metal seal ring unit may be employed to ob-tain a simultaneous seal with the first metal seal ring unit to isolate the high pressure section from the low pressure section at the completion of the power stroke of the piston.  Alternatively, an elastomer or a knife-edge metal-to-metal type static seal may be substituted for the third metal seal ring unit.  Deformable means positioned adjacent the first metal seal ring unit ensures that the third metal seal ring unit effects a seal once the first metal seal ring unit effects its seal.  The actuator may be employed to operate a subsurface safety valve used to control flow of fluids through a well tubing and may be located external of the well tubing with the piston being linked to a valve operator.  Means may be provided to compensate for any differences in travel between the pis-ton and valve operator.
