Abstract: Abstract Of The Disclosure The invention relates to the reaction of cyclopentadienyl-transition metal cumpounds, (C5H5)2M or C5H5-M(L)n (M= transition metal, L = olefin), with alkali metal in the presence of olefins, with detachment of the C5H5 rings from the transi-tion metal atom to form alkali metal cyclopentadienide, leads, to transition metal-olefin complex compounds free of alkali metal or also containing alkali metal, in yields of greater than 65%, the latter compounds being able to contain one or even several alkali metal atoms per transition metal atom.     It is moreover possible, depending on the selection of the stoichiometry or of the reaction compounds, and depend-ing on the nature of the transition metal, to detach only one or also both cyclopentadienyl rings from the transition metal atom, so that by this method the most various transi-tion metal-olefin complex compounds can be prepared, namely transition metal-olefin complex compounds containing C5H5 or alkali metal-transition metal-olefin complex compounds free of C5H5.

Abstract: ABSTRACT OF THE DISCLOSURE          A railway truck assembly adapted to produce steering of the wheel axles radially to a curve to reduce wear and noise and characterized by a pivot connection between the bolster and the truck frame elements which; in cooperation with direct trans-mission of the load to the truck frame through the opposite ends of the bolster, allows to use a relatively thinner and centrally non-bulging bolster.  Thus, more space is made available between the central portion of the bolster and the top of the rails; which space is advantageously used to install some equipment such as for instance a linear induction motor or LIM.  This railway truck assembly comprises a bolster which is substantially bodily displaceable with the  car body, a pair of side frames, laterally restrained relative to the bolster and supporting the opposite ends respectively of the bolster, a pair of steering yokes longitudinally restrained relative to the car body and pivoted one to the other for radial steering of the wheel axles connected to them respectively, the side frames being slidably supported by the yokes and laterally restrained relative to the latter, and links producing the aforementioned restraints respectively.

Abstract: ABSTRACT OF THE DISCLOSURE     An electro-mechanical impact device, useful for driving nails, staples and other fastening elements.  The driving member is driven by frictional engagement between a pair of counter-rotating high speed flywheels.  The device has a safety provision whereby it cannot be actuated until the nose of the device is pressed against a work piece.          This action also produces a movement of one of the flywheels toward the other.  Actuation of the trigger moves the driving member into engagement between the counter-rotating flywheels, and these propel the driving element in a fastener driving direction.   The inertia of the movable flywheel aids in efficient engagement of the flywheels with the driving member, and the movable flywheel is provided with a leaf spring permitting it to yield so that the driving member can pass between the flywheels while maintaining frictional engage-ment between the flywheels and the driving member.   The driver is connected to an elastic member, so that when the tool is lifted from the work, the movable flywheel is moved away from the fixed flywheel, and the elastic member then retracts the driving member between the flywheels to a position out of contact therewith.  The two flywheels are driven in synchronism by a single electric motor.

Abstract: CONTROL SYSTEM FOR PHASE DISPLACEMENT REGULATOR CIRCUITS    ABSTRACT OF THE DISCLOSURE    A control circuit for a regulator circuit of the type in which the regulator output voltage and current are dependent upon the phase angle between an unregulated a-c input voltage wave and a regulating or control voltage wave.  The control circuit generates a reference signal that is locked in phase with the a-c input voltage wave and a control signal that is locked in phase with the control voltage wave.  Output voltage sensing circuitry is arranged to increase or decrease the phase angle between the control signal and the reference signal, as required, to maintain the output voltage of the regulator at the desired, regulated value.  A phase difference limiting network allows the control signal to vary freely in phase with respect to the reference signal so long as the control signal remains within an angular window of from 0° to 60° of lag behind the reference signal and assures that limits of this angular window cannot be exceeded.  A damping signal is utilized to assure that the rate of change of the phase angle between the control and reference signal is limited in a manner which affords both high control system stability and rapid dynamic response to changes in input voltage and output current.  OR-ing circuitry is also provided to allow the output current to reduce the regulator output voltage and thereby limit the regulator output current to a safe value when the output current attempts to rise beyond its highest rated value.

Abstract: Abstract of the Disclosure An easy-opening convenience end for containers has a push tab formed out of the end and displaced beneath the plane of the end with a folded edge circumscribing the outer periphery of the push tab, except for a limited hinge section.  The folded edge merges into the thickness of the end adjacent to the hinge section, and a line of weakening is formed by a metal shearing operation to per-mit opening by depression of the tab inwardly about its hinge section.  Reinforcing areas may surround opposite sides of the tab to initiate separation of the tab from the end, and a raised presure pad aids in severance of the panel.  In one of the modified forms, the tab is raised upwardly through the aperture formed in the end and a depressed area strengthens and encourages localized separation of the tab.
