Abstract: ABSTRACT OF THE DISCLOSURE          An improved method and apparatus for recording and playing back a video signal on a video disc, such that selected video frames can be played back in a stop-motion fashion, with accompanying audio.   Each stop-motion video frame is recorded on a single recording track on the disc, and an associated digitized stop-motion audio signal is combined with a continuous-play video signal and recorded on a plurality of preceding tracks.  During playback, the tracks recording the continuous-play video signal are first scanned, to recover and display the contin-uous-play video frames, and to recover and enter into a memory the digitized stop-motion audio signal.  The track recording the corresponding stop-motion video signal is then scanned, in a repeated fashion, to provide a stop-motion display of the video frame, while the stop-motion audio signal is extracted from the memory and converted back to its original analog format, for playback along with the stop-motion video frame.

Abstract: ABSTRACT OF THE DISCLOSURE         The orthogonal components of the voltage vector of an a-c voltage network are transformed by means of a vector rotator, smoothed and transformed back.  The frequency of the transformation elements required for the transformation in the vector rotator is set during a network disturbance under controlled conditions in accordance with a stored frequency value.  After the end of the network disturbance, the direction given by the smoothed transformed orthogonal components is controlled to a reference value in that the frequency of the transformation elements is readjusted according to the direction deviation.  The phase of the transformation elements determines the phase of the co-system fundamental of the network.  A counter system fundamental can also be taken into consideration.  Also if the returning power network contains asymmetrical and harmonic containing transients, a reference voltage synchronous with the fundamental can be obtained thereby within a few milliseconds for synchronizing network controlled converters.

Abstract: Abrasive Surfaced Article for High Temperature Service Abstract A very thin abrasive material on a substrate is comprised of ceramic particulates contained within a metal matrix.  The particulates extend fully through the matrix from the substrate surface to the machined free surface of the abrasive.  In a representative 0.38 mm abrasive the particulates are sized nominally at 0.42-0.50 mm and have an aspect ratio of less than 1.9 to 1.  This enables a high density of particulates, in the range 33-62 per cm2, while at the same time ensuring good bonding in that most of the particulates are fully surrounded by matrix.  When the abrasive is applied to the tip of a superalloy gas turbine engine blade, about 10-50% of the matrix metal is removed after machining. This allows the machined ceramic particulates to project into space and to thus better interact with ceramic abradable seals.  In the preferred practice of the invention the particulates are alumina coated silicon carbide contained in a nickel superalloy matrix.

Abstract: ABSTRACT OF THE INVENTION A lipid membrane is used as a chemo-receptive transducer in an electrochemical cell, for quantitative and semi-quantitative analysis of chemical test species in an aqueous electrolytic solution.  The lipid membrane includes a complexing agent having a high degree of selectivity towards the chemical species.  Electrical potential difference is applied across the membrane to produce an analytical signal.  From measurements of the analytical signal, a quantitative analysis of the chemical species may be conducted, on a highly selective basis.     In one embodiment, the membrane is deposited onto a ion conductive support.  In another embodiment, the complexing agent is selective for an inorganic ion and the membrane is consequently ion-selective.  This embodiment is useful for forming a gas-sensor electro-chemical cell.  In a further embodiment, the complexing agent is a receptor selective for an organic chemical species, and the membrane is organic selective.

Power  from  the motive source  is used to rotate the boom.   When  supported  on transport  wheels,  the hinged wing sections can move between  an aligned working position along the axis of the center section and a transport position,  trailing at right angles behind the center section for transport.   In the working position,  the power also is used to adjust the spray tube height,  to accommodate variable spraying requirements.   The wing sections of the boom are partly drawn, in working position, by rigid boom draws which are latched and  unlatched  from  the  motive  power  source  by  appropriate movement of the boom.

Abstract: Abstract of the Disclosure A surgical carbon dioxide laser is disclosed which includes a handpiece for directing a laser beam to a desired location.  Mounted on the forward end of the handpiece is a hollow needle precisely aligned along the laser path.  This permits the laser to be used in surgical applications where the needle perfo-rates a portion of tissue to provide the laser beam direct access to distal tissue.  The needle is mounted to the handpiece in a manner which provides for forward and lateral adjustment of the needle relative to the laser beam path which insures co-axiality between the laser beam and the needle lumen.  This is crucial for the safe use of the laser.  The needle is adjusted such that the focal point of the laser beam is approximately at the tip of the needle.  This provides maximum energy at the tip of the needle where it is required.  This apparatus is particularly useful in transmyocardial devices utilized to provide ischemic endocardial tissue direct access to blood within the ventricular cavity.  The device is inserted within the epicardium of the heart; the laser is then activated to vaporize a channel of tissue through the endocardium. This provides for perforation of the endocardium with minimal damage to the epicardium.

Abstract: Abstract:    A hydraulic control solenoid valve has a plunger provided in a coil case and a shaft shiftable freely in a body.  The shaft carries a first spool valve and a second spool valve. A feedback chamber is provided in the body adjacent the first spool valve.  A thin circular plate is fixed to the end of the first spool valve and is positioned in the feedback chamber to form a constriction of a flow passage formed between an inside wall of the feedback chamber and a peripheral surface of the plate.   The cross-sectional area of the constriction is not larger than 0.04 times the side surface area of the plate. The plate adds a damping coefficient and also functions for stabilization of the behavior of the spool valves.  The plate thus facilitates prevention of the resonance phenomenon in the spool valves.

Abstract: Abstract of the Disclosure A laser is provided comprising a laser envelope and a gain medium disposed in the laser envelope.  The gain medium comprises a compound subject to dissociation into a plurality of components.  Circuitry is included for generating an electrical discharge in the laser envelope, a portion of the electrical discharge passing through the gain medium and dissociating a portion of the compound thereof into the plurality of components.  The discharge generating circuitry comprises a cathode, the cathode comprising a first portion for emitting the electrical discharge toward an anode. Such first portion comprises a catalyst for aiding the recombina-tion of the dissociated plurality of components.  The first portion of the cathode sputters particulates therefrom during the electrical discharge and a surface is disposed within the laser envelope for collecting the sputtered particulates.          Means, including a second portion of said cathode, are addi-tionally provided for spacing the first portion of the cathode sufficiently from the collecting surface to substantially prevent the electrical discharge from being emitted from the first portion to the collected particulates, and thereby constrain the electrical discharge to occur substantially directly between the cathode and the anode. With such arrangement, the sputtered particulates are inhibited from entering the resonant cavity of the laser and adhering to the optics thereof.  Thus, the useful operating life of the laser is increased.
