Abstract: Multiple Stage Magnetic Railgun Accelerator Abstract A multiple stage magnetic railgun accelerator (10) for use as a projectile launch device by accelerating a projectile (15) by movement of a plasma arc (13) along the rails (11,12).  The railgun (10) is divided into a plurality of successive rail stages (10a-n) which are sequentially energized by separate energy sources (14a-n) as the projectile (14) moves through the bore (17) of the railgun (10).  Propagation of energy from an energized rail stage back towards the breech end (29) of the railgun (10) can be prevented by connection of the energy sources (14a-n) to the rails (11,12) through isolation diodes (34a-n).  Propagation of energy from an energized rail stage back towards the breech end of the railgun can also be prevented by dividing the rails (11,12) into electrically isolated rail sections (11a-n, 12a-n).  In such case apparatus (55a-n) is used to extinguish the arc at the end of each energized stage and a fuse (31) or laser device (61) is used to initiate a new plasma arc in the next energized rail stage.

Abstract: ABSTRACT OF THE DISCLOSURE        The present invention relates to dininfectant compositions.       A bactericidal and fungicidal composition contains the polymer of hexamethylenehexamethylene biguanide (PHNB) and a quaternary ammonium compound. This composition brings an  inoculum after one minute contact time to 0.0001% of the initial bacterial population, that is if the population  count is 107 germs per ml, only 10 germs will survive. A film forming polymer can also be added, such as for example polyvinylpyrrolidone, in order to obtain a film showing long-lasting germicidal properties.       The invention finds an application in the disinfection of medical staff's hands and of linen and clothing soiled with proteins, blood, pus, etc.

Abstract: ABSTRACT OF THE DISCLOSURE            Drilling apparatus includes an inclined mast, a drive carriage slidably mounted on the mast for rotating a tubular drilling member, and at least two positioning units secured to the mast at spaced positions therealong for positioning tubular drilling members.  Each position-ing unit has a frame which can be raised a preset distance above the mast and lowered from the preset distance.  Grippers adjacent opposite sides of the frame can be raised a preset distance above the frame and lowered from the preset dis-tance.  The grippers can be moved towards one another to grip a tubular drilling member therebetween and moved away from one another to release the tubular drilling member.          Locators  adjacent opposite sides of the frame can be raised to cause the locators to engage and position lower parts of the tubular member, with the tubular member being movable away from the mast out of contact with the locators without moving the locators.  The drive carriage is movable along the mast past at least one positioning unit.

Abstract: ABSTRACT OF THE DISCLOSURE     The floor of the furnace space [fire chamber] of the heating fireplace is constituted by a horizontal, flat part and the rear wall of the furnace space is constituted in part by a vertical flat part of a heat exchanger serving for  heating water for a hot water heater.  Heat is trans-ferred to the water on the sides of the heat exchanger facing the furnace space, and to two fresh air currents on the sides of the heat exchanger facing away from the furnace space.  One of these air currents extends under the horizontal heat exchanger part and is fed through an opening therein to the fire as combustion air; the other air current extends in a downdraft duct along the rear wall of the furnace space and further through an updraft duct exposed to the heat of the fire and is fed to the room to be heated as heated, fresh air.

Abstract: DEVICE FOR MAKING TWO AXIALLY PARALLEL BORES               ABSTRACT OF THE DISCLOSURE            A device is disclosed for cutting two parallel partially intersecting bores, such as the bores used in a screw type compressor housing, comprising, a device housing, a pair of spindles rotatably mounted to the housing and a tool holder connected near the end of each spindle.  The spindles are engaged with each other through gears so that rotation of one spindle in one direction causes rotation of the other spindle in opposite direction.  A drive shaft is connected to one of the spindles for rotating the pair of spindles simultaneously. Each tool holder is elongated along a major tool holder axis thereof which is substantially transverse to an axis of its associated spindle.  The major axes of the two tool holders are always substantially perpendicular to each other so that free rotation of the two spindles, in opposite directions is possible.  The size of each tool holder and each spindle adjacent each tool holder is chosen so that there is always a minimum clearance between each tool holder and the spindle carrying the other tool holder.

Abstract: TITLE            INLET AIR CONTROL FOR STOVE OR FURNACE     ABSTRACT          A control regulates the rate of flow of com-bustion air flowing into an airtight stove or furnace 10 containing a fire.  A control element 15 or 45 is arranged in communication with the air inflow stream and moves in response to the velocity of the flowing air. The control element 15 or 45 moves to constrict the area of the inflow stream as air velocity increases and to open the area of the inflow stream as air velocity di-minishes.  Springs 25 and 26 or 60-62 bias the control element toward a maximum opening and the spring bias is non-linear to provide increasing resistance to movement as the control element approaches a closed position. The spring bias system is preferably adjustable to vary the air inflow rate that is otherwise kept steady by the control element.

Abstract: REINFORCED WINDOW ASSEMBLY                Abstract of the Disclosure A sash assembly for a glazing panel.  The sash members of the assembly are formed with a concave inner surface which con-tains a rigid reinforcement member.  The reinforcement member interlocks with retainers which extend from the inner surface of the sash member to provide rigidity to the sidewalls of the sash member when it supports the glazing panel.  The sash members are preferably of extruded construction and are formed with an open compartment which allows for greater ease and speed of production.  Such open compartment construction permits the use of extrusion dies and downstream forming equipment which are simpler and less expensive than conventional equipment.  Also, cooling and forming of the extruded material is speeded since all sides of the sash member may be uniformly cooled rather than only the exterior of an enclosed compartment.  This also yields a sash member having a more uniform shape and less internal stress.  The rigid support inserted within the sash member is used to pull the side walls of the sash member together and provide strength without the necessity of utilizing webbing between the side walls which forms an enclosed compartment.

Abstract: TITLE OF THE INVENTION          Printing and/or correcting device for printing machines.            INVENTOR          Remo Falconieri, residing at Str. per Cuceglio 10090 S.  Giorgio Canavese (Turin) Italy ABSTRACT OF THE INVENTION          The printing and correcting device is applied to a daisywheel printer and comprises a  frame supporting a cartridge for a typing ribbon and a correcting ribbon arranged below the typing ribbon. The frame is able to swing as the result of operation of an electromagnet, from a rest position provid-ing visibility of the print, to an intermediate position for printing the characters. A second electromanget raises the frame through a greater length of travel in order to posi-tion the correcting ribbon in front of the printing point. A rotating electromagnet causes automatic unidirectional advance of the typing ribbon after each character has been printed. The correcting ribbon is wound between two spools and its  motion is provided by means of a pawl which engages with a gear wheel for driving the spool only in the case where the path of travel of frame is greater than that which relates to positioning of the typing ribbon. A paper finger in the from of a sheet of limited thickness is provided with acute out portion corresponding to the printing point, and with a guide in the from of a leaf spring for guiding the two ribbons adjacently to the typing paper when they are being raised and for preventing unwanted contact by these.
