Abstract: A B S T R A C T           A safety syringe, such as a dental syringe, comprising a hollow cylinder, a disposable, prefilled fluid medication carpule received within the interior of the cylinder, and a needle carrying hub supporting a needle cannula so that the cannula extends axially from the carpule and outwardly of the cylinder, whereby to administer an injection.  A piston assembly is movable axially through the carpule to first expulse the medication therefrom and to then engage and retract the needle hub and its associated needle cannula into the carpule, so that the needle will be completely surrounded and shielded by said carpule.  A slide lock is connected around one end of the medication carpule and interfaced with the needle carrying hub to control the relocation of the hub and corresponding retraction of the cannula through the carpule.  The slide lock is selectively moved relative to the carpule between needle retaining and needle releasing positions to either anchor the needle carrying hub with the needle extending axially from the carpule for administering an injection or release the needle carrying hub for retracting the cannula into its carpule to permit a safe disposal of the needle while avoiding an accidental and potentially life threatening needle strike.

Abstract: Abstract A computer having a file management system is presented.  The file management system includes a plurality of application programs, a plurality of data files a plurality of class data structures and a plurality of object data structures.  Each class data structure includes a reference to an application program within the plurality of application programs. Each object data structure includes a reference to a class data structure from the plurality of class data structures and a reference to at least one data file from the plurality of data files.    The use of object data structures adds a layer between a user of the computer and data files.  This allows for the computer to refer to an object data structure and access file  associated therewith using a tag which is inaccessible to the user.  The user refers to an object based on the physical location of the object on the screen.  The user may also give the object data structure a name, which is wholly unconnected to the value of the tag.  This allows a user to, for instance, give two objects in the same directory, the same name.    Additionally, the file management system includes a plurality of link data structures, each link data structure including a reference to a first object data structure in the plurality of object data structures which serves a parent object of the link, and including a reference to a second object data structure in the plurality of object data structures which serves as a child object of the link. Child objects and parent objects are not necessarily the same for each link data structure.

Abstract: SPEED GOVERNING APPARATUS Abstract of the Disclosure A speed governing apparatus for an internal combustion engine.  A plurality of flyweights are pivoted to a flyweight carrier mounted on the cam shaft of the engine and a surface of each flyweight is engag-ed with the end of a spool that is mounted for rotation with the cam shaft, but can move axially thereof.  A spring loaded non-rotatable fork straddles the cam shaft and is engaged with the opposite end of the spool.  The fork is secured to a rod which, in turn, is operably connected to the throttle of the engine.  The end of the spool, against which the fork rides, is an undulating cam surface which results in the continuous axial oscillation of the spool, and corresponding con-tinuous radial oscillation of the flyweights relative to the spool, during operation of the engine.  The radial oscillation of the flyweights relative to the spool reduces the frictional forces, so that under varying load conditions the spool can be more readily moved by the pivoting action of the flyweights to pro-vide more precise speed control.

Abstract: ABSTRACT     An implantable ventricular assist system uses a small high-speed axial flow blood pump which may be grafted into the patient's circulatory system. The pump includes a blood tube in which the pump rotor and stator are coaxially contained, and a motor stator surrounding the blood duct. A permanent magnet motor rotor is integral with the pump rotor. Purge fluid for the hydrodynamic bearings of the device and power for the motor are preferably percutaneously introduced from extracorporeal sources worn by the patient. The purge fluid is introduced into the pump stator blades. this construction avoids the creation of discontinuities in the blood path wall due to the routing of drive power and/or fluid supply elements through the blood path wall. The described construction greatly reduces the size of the implant needed for a given blood flow rate and enhances its physiological compatibility with the body. specifically, the system of this invention minimizes the risk of infection by reducing vibration, minimizing the size of the percutaneous conduit, and directing most of the heat generated by the pump into the blood.

Abstract: The invention relates to a pallet (1) made of recyclable cardboard and its method of manufacture. Beams (2) are formed of tube-like paper-board core pieces (3) arranged in line and of the cardboard (4) surrounding them, the beams being attached to each other crosswise in two layers so that the axes of the core pieces included in the beams are placed perpendicularly to the level of the pallet. In addition to the beams (2), the pallet (1) may include a covering plate (14) of cardboard and an intermediate plate (15) of cardboard between the layers of the beams. The invention is characterized in that, when assembling the beams (2), the paper-board core pieces (3) of essentially a round cross section are compressed in order to flatten them in the cross direction of the resulting beam. The diameter of the core pieces (3) is decreased by 1-20 %, suitably about 10 % in said direction during flattening. The flattening increases the contact surfaces between the core pieces (3) and the surrounding cardboard (4) on which the core pieces and the cardboard are glued to each other.

Other types of metal treating furnaces and accessory equipment may also be cooled with the system of the invention. In the invention, spray headers and pipes (14, 16, 18) supply coolant to spray nozzles (70) distributed within a coolant space in a roof structure (10) to spray coolant against the working plates (22) of the roof. The spray pipes and headers also comprise part of the framework for the roof, resulting in a simple, lightweight, one-piece structure. A pump (56) is connected to evacuate the coolant from the coolant space, and thermocouples (58) are embedded in the working plates to monitor their temperature and operate controls to adjust the flow rate so that only the amount of coolant necessary to maintain a desired temperature is supplied to the roof. The sprays of coolant produce many small droplets which provide a large surface area for more effective cooling, and at least a substantial portion of the droplets are vaporized during cooling whereby the latent heat of vaporization of the coolant is utilized to provide a significantly increased cooling rate. Similar arrangements may be used to cool the delta and/or sidewall of the furnace. The method of cooling a furnace by directing sprays of coolant against the working plates is also disclosed.

Abstract: DEVICE FOR COMBINED CARDIAC PACING AND DEFIBRILLATION     ABSTRACT OF THE DISCLOSURE         A method is disclosed for combined cardiac pacing  and  defibrillating  with  an  implanted  pacer/ defibrillator having sensing and pacing leads connected to the atrium and the ventricle.  P-waves and R-waves are sensed, and a V-V timer and a V-A timer are reset if an R-wave is sensed.  If an R-wave is sensed during the V-V timer interval, a pacing stimulus to the ventricle is inhibited.  If a P-wave is sensed during the V-A timer interval, a pacing stimulus to the atrium is inhibited.       If an R-wave is sensed during the V-V timer interval, arrhythmia  therapy  is provided  if an  arrhythmia  is determined to be present.  If the sensed ventricular rate is greater than a selected tachycardia rate but is less than a selected fibrillation rate, then a determination is made whether the sensed atrial rate is greater than a selected fibrillation rate, and if so, the V-V and V-A timers are reset, but if the sensed atrial rate is not greater  than  a  selected  fibrillation  rate,  then arrhythmia therapy is provided.   If an arrhythmia is present, the charging of a capacitor commences but if the arrhythmia ceases, the charging discontinues.   If the capacitor is charged and the arrhythmia is still present, then a shock is delivered to the heart during a time period that is outside the vulnerable zones of the atrium and the ventricle.
