Abstract: ABSTRACT OF THE DISCLOSURE              A pneumatic impact mechanism for driving rod-like members having a hollow cylindrical casing with a tail portion and a front end portion. The casing accommodates a reciprocating stepped hammer piston defining in the casing, on the tail portion side, a variable volume rear end work chamber in permanent communication with a source of compress-ed air. The stepped hammer piston defines, on the side of the front end portion, a variable volume front end work chamber.            The stepped hammer piston has a through-passing axial bore, and its small-diameter portion cooperates with the tail portion and has radial bores. There is provided a tubular guide member for receiving the rod-like member arranged coaxially with the stepped hammer piston and casing and se-cured to the tail portion and to the front end portion of the casing in such a manner as to cooperate with the stepped hammer piston and define therewith, with the outer periphery thereof an axial passage. A clamp for retaining rod-like member is rigidly secured to the front end portion of the casing. The front end-work chamber communicates, at regular intervals, with atmosphere through the axial passage and radial bores when the stepped hammer piston is in the rear end position and with the rear end work chamber when the stepped hammer piston is in the front end position to deliver blows to the casing under the action compressed air fed to the work chambers.

Abstract: ABSTRACT OF THE DISCLOSURE            In an electrophotographic copier a fusing station is provided at which a toner image previously formed on a copy carrier is fixed on the carrier by fusing.  The fusing station includes a flash tube which, when discharged, produces the heat required for the fusing operation.  The electrical energy required by the flash tube is supplied from a flash capacitor.  To avoid current spikes during charging of the flash capacitor the same receives its cur-rent from a drive system which includes a motor-driven generator in circuit with the flash tube;  the inertia of the drive system acts as a buffer between the flash capacitor and the current supply source and prevents the occurrence of current peaks during the charging of the capacitor.

Abstract: ABSTRACT         An apparatus for insulating against conductive, con-vective, and radiant heat transmission comprises a plurality of substantially non-transparent and generally parallel sheets.          The sheets may be attached to a retracting device from which they can be drawn to extend and cover a building opening such as a window or onto which they can be retracted to uncover the opening.  A number of spacers which may be in the form of collapsible or nestable devices are mounted within the apparatus to separate each pair of adjacent sheets and, thus, define a dead air space therebetween.  At least one of the sheets has a surface, facing on the dead air space, that exhibits a low sur-face emittance.  This surface emittance is sufficiently low to yield a total effective emissivity of the surface and dead air space of no greater than 0.60.  Importantly, the spacer devices are designed so as not to abrade or otherwise harm the reflec-tive surface.  The combination of these dead air spaces with the low emittance surface synergistically results in an apparatus having low total effective emissivity that effectively impedes radiant heat transfer.  The dead air spaces also effectively impede conductive and convective heat transfer.

Abstract: ABSTRACT OF THE DISCLOSURE           A valve is reciprocable between opened and closed positions along a longitudinal axis and is rotatable about the axis by a rotator mechanism.  The rotator mechanism includes first and second parts movable axially and rotatably relative to one another along and about the longitudinal axis.  A plurality of shiftable ball elements are located between the first and second parts and are movable along predetermined paths for imparting relative rotation between the parts during relative axial movement therebetween.  Each ball is constrained for movement along its predetermined path by surfaces which define a pocket in one member and in which the ball is located. Each of the pockets have a ramp along which the ball moves upon relative axial movement of the parts.  A spring biases the ball to one end of the ramp and the ball moves toward the other end of the ramp when the first and second parts move axially towards each other.  The ramp is defined by a plurality of surface portions which extend at different angles to a plane extending perpendicular to the longitudinal axis.  The surface portion adjacent the one end of the ramp to which the ball is biased extends at the greatest angle to the plane and the angle at which the other surface portions extend to the plane are progressively less as the ramp progresses toward the other end of the pocket.

Abstract: ABSTRACT OF THE DISCLOSURE         A piston cylinder assembly is disclosed which may be used in new internal combustion engines of various types and which may be used to retrofit existing types of internal combustion engines to as to provide a high thermodynamic cycle efficiency and to substantially reduce the volume of pollutant gases exhausted from the engine.  The assembly in-cludes a piston having a centrally positioned generally cir-cular first piston surface which is surrounded by a general-ly concentric annular second piston surface.  The first and second piston surfaces are separated by an annular groove which accommodates a cylindrical wall of a cylinder assembly.          The piston reciprocates in the fixed cylinder assembly and cooperates with the cylinder assembly to define an annular expansion/exhaust chamber.  Reciprocably mounted with respect to the cylinder assembly is a movable head assembly which cooperates with the cylinder assembly and the piston to de-fine a centrally disposed intake/compression chamber.  The cylindrical wall includes a port which is valved by the movable head assembly to control communication between the intake/compression chamber and the expansion/exhaust chamber.          Movement of the movable head assembly is also adapted to schedule the compression of the central chamber.  The maximum volume of the expansion/exhaust chamber is selected to reduce pressure of combustion products to a value near or below ambient pressure.
