Abstract: TRACHEOSTOMY APPARATUS AND METHOD                   ABSTRACT OF THE DISCLOSURE           An apparatus and method for performing percuta-neous or non-dissection tracheostomies.  An outer needle coaxially slidably receives an inner needle which is attached to a syringe adapted for use in inserting the needles within the tracheal lumen.  Operation of the syringe confirms proper location of the needles within the lumen.  An elongated dilator coaxially slidably mounts a trachea tube, and its proximal extremity constitutes an introducer portion which tapers to a distal end to which is attached an elongated, flexible leader adapted for insertion through a bore of the outer needle subsequent withdrawal of the inner syringe needle.  A slot in the outer needle enables lateral sepa-ration of the leader from the outer needle to allow removal of the outer needle from the trachea.  The dilator includes a recessed cutting edge for cutting tissue compressed against it during forcible insertion of the introducer portion into the tracheal lumen along the path defined by the leader.          The dilator is slidably removable to leave the tracheal tube in breathing position.

Abstract: "DICTATION DISPLAY DEVICE"           Abstract A display device for use in a dictation transcription station comprising a plurality of selectively actuatable lighted segments.  A pair of shift registers are used to retain information as to the location of recorded signals denoting ends of dictation segments and location of instructions.  As rewound tape is transcribed a third shift register creates a shutter comprising contiguous lighted segments which moves to the right during a transcription operation.  Control circuitry allow shifting of the registers containing the end of segment and instruction marks to occur only when the tape is rewound past the farthest point reached during a previous rewinding operation.  A display for a dictation recorder is also shown wherein a pair of up down counters control numerical displays representing the total length of tape used and the length of the present dictation segment.  Apparatus which is sensitive to rewinding of the tape into a previous dictation segment is used to control the present segment counter.  The present segment counter may be selectively made to begin counting again upon either entry into the next dictation segment encountered during forward advance or the segment in which dictation was occurring when the rewound operation was initiated.

Abstract: ABSTRACT     TOILET SEAT LIFTING DEVICE     An operator-controlled, toilet-seat lifting device applies a constant bias force, for example, by means of a helical spring, to the seat in a direction tending to raise the seat.          The weight of the seat is sufficient to overcome the constant bias force so that the seat normally assumes a horizontal or down position.  To raise the seat the user increases the bias force, for example, by depressing a foot-operated pedal connected to the bias means, so as to overcome the weight of the seat and cause the seat to swing upwardly.  As the seat is held in raised position solely by bias force, forcible manual lowering of the seat when in its raised position does not damage any of the components.

Abstract: PAVEMENT BREAKING APPARATUS     ABSTRACT        Apparatus for breaking concrete and asphalt pave-ment and the like comprising a frame adapted to be sup-ported by and above pavement to be broken.  Power operated means move the frame in one and opposite directions rela-tive to and in parallel relationship with the pavement.  A plurality of air hammers are supported in a gang parallel arrangement by the frame with their cutting tools aligned in a closely spaced parallel series.  Cutting ends of the tools are adjacent the pavement with the series of tools extending in one direction and frame movement occurs in a direction substantially at right angles relative thereto.        Thus, the frame movement defines a predetermined generally rectangular path of movement and pavement breaking opera-tion of the cutting tools.  A cradle on the frame is move-able relative to the frame for adjusting both the height and the angle of attack of the cutting tools relative to the pavement.  The angle of attack is adjustable so as to be displaced substantially from the plane of the pavement and from a plane perpendicular thereto, the tools thus being adapted to hardness and other pavement character-istics.  In one form the frame is mounted on a fixed frame and is moveable therealong by a power operated means.  In a second form the frame is mounted on a self-propelled vehicle for movement with the vehicle parallel to the pavement.

Abstract: ABSTRACT OF THE DISCLOSURE           In an apparatus for the digital measurements of an angle, means are provided for course and fine measurement.  For the course measurement, full intervals of a generated periodic signal are counted, and for the fine measurement, a reference mark is provided within the periodic signals.  For this purpose, legs of the angle to be measured are defined by two parts e.g. a stator and a rotor which are rotatably mounted with respect to one another about a common axis or shaft.  A disk rotating at a constant angular velocity about the same axis with constant angular velocity supports a circular graduation made up of equidistant radial lines or sectors and gaps.  Lines and gaps are sensed by appropriate sensor or pick-up elements.  The above said reference mark is realised by disturbing the line width.  One edge of all the scale divisions still represents an undisturbed equidistant division extending over the entire disk circle and is used for course phase measurement.  The mark disturbance only consists of a displacement of the other edge and is used for fine measurement.

Abstract: ABSTRACT OF THE DISCLOSURE     A process for recovery of valuable metals such as prin-cipally nickel and vanadium deposited on used catalyst from catalytic  hydroprocessing of  hydrocarbon metals-containing feedstocks.   In  the process,  the used catalyst containing metals deposits is treated with a fresh dilute acid solution such as sulfuric acid to extract and remove the metals depo-sits   without  damage  to  the  catalyst,  after  which  the resulting  spent  acid  solution  containing  metal  salts  is neutralized to a pH of about 3.5-12 with a hydroxide solu-tion sufficient to form a metal salts precipitate material.          The precipitate material is removed from the liquid such as by filtering, and the precipitate is then heated to evolve water vapor and the water of hydration,  leaving oxides of metals such as nickel  and vanadium as product.   If desired to recover nickel and vanadium oxides separately, the metal oxide material can be further furnace heated with carbon to the respective melting temperatures of the metals, which are successively   separately   drained   from   the   furnace.          Alternatively, to remove nickel and vanadium oxides separa-tely, the spent acid solution containing metal salts is first neutralized with hydroxide solution to a pH of about 3.5-5.0 to precipitate and recover the nickel salts.  Upon further addition of hydroxide solution sufficient to neutralize the remaining spent acid solution to a pH of 7-12, vanadium and other metal salts are precipitated and recovered.
