Abstract: Abstract of the Disclosure A pulling tool which comprises a pulling bar which, in a simple form, comprises an L-shaped length of tool steel r o d and a pulling hook which comprises a length of tool steel rod having a hook formed in one end thereof for hooking the pulling hook with one leg of the pulling bar.  The opposite end of the pulling hook can be adapted to have coupling means affixed to it for pulling on the pulling hook.         To use the pulling tool, two holes are drilled in the body of the vehicle in the damaged area, and in spaced apart relationship.  One leg of the L-shaped pulling bar is inserted through one of the holes, and the pulling bar is manipulated so that the leg extended through the hole extends substantially parallel with the surface contour of the body of the vehicle, and so as to project towards the second hole drilled in the body.  The hook on the pulling hook then is extended through the other hole formed in the body of the vehicle and hooked with the leg of the pulling bar.  In this fashion, a pulling force can be exerted on the body of the vehicle to repair the damaged area thereof by pulling on one or both of the pulling hook and the pulling bar.  The need to remove any body panels to gain access to the back side of the body to secure the pulling tool to the body therefore is eliminated.  Also, both the pulling bar and the pulling hook are formed in a manner such as to prevent the formation of a dimple in the body, upon exerting a pulling force on the pulling tool to remove the dent from the body.

Abstract: VIBRATION ISOLATION SYSTEM                 ABSTRACT OF THE DISCLOSURE         A vibration isolation system wherein a vibrating mass such as a helicopter rotor-transmission assembly is spring coupled to a body to be isolated, such as the helicopter fuse-lage, at a plurality of points.  Each coupling point includes, in addition to a coupling spring, a weighted lever arm pivot-ally connected to the vibrating mass and to the body, with the body-to-lever pivot connection lying between the center of gravity of the arm and the vibrating mass-to-lever pivot con-nection.  The coupling spring is in the form of a torsion spring, e.g., torsion bar, coupled between the body and the lever arm at the pivot connection therebetween.  Vibratory forces of a predetermined frequency transmitted from the vibrating mass to the body through the spring are substantially cancelled by inertial forces generated by the lever and applied to the body through the body-to-lever pivot connection, thus isolating the body from the vibrating mass at the predetermined frequency.          A second form of isolation coupler is disclosed wherein a spring-mass structure is connected to the lever arm and tuned so that vibratory forces of a second, higher, predetermined frequency are also substantially cancelled by the inertial forces coupled to the body through the pivot connection between the body and the lever arm.

Abstract: FREQUENCY STABILIZED MICROWAVE SIGNAL SOURCE by Volker B. Weise ABSTRACT OF DISCLOSURE     The frequency of a microwave oscillator is stabilized by coupling a portion of the RF signal therefrom to an HF oscillator operating at a sub-multiple of the microwave frequency and producing a strong harmonic at the microwave frequency in order to cause the operation of the microwave and HF oscillators to be locked together. The HF signal frequency, which includes any drift in the micro-wave oscillator frequency, is divided down a specified amount and compared with the frequency of a stable crystal reference oscillator in a comparator.  The output of the comparator is a DC error voltage which is proportional to any drift in the frequency of the microwave oscillator.  This error voltage is applied to the microwave oscillator to cause the operating frequency thereof to be more nearly constant.

Abstract: FLAILING MACHINE FOR FELLED TREES          Abstract of the Disclosure This invention relates to a flailing machine for stripping branches and/or bark from felled trees.  The machine is adapted for operation from the end of an extendible and rotatable boom of a logging vehicle so that the trees can be stripped actually on the felling site.  The machine has a multiple flail element with attached flails and which rotates in a generally horizontal plane.  The flail element is supported above a felled tree to be stripped and the flails remove branches and bark.  The support for the flail element is attached to the end of the boom arm by a rotatable coupling enabling the machine to be rotated around a vertical axis.  A drive mechanism enables the operator of the vehicle to orient the flailing machine with respect to the felled trees to achieve the most efficient stripping effect.  In a preferred form, the machine also has a topping device for cutting off the unwanted top portions of the tree. This can also be operated easily by the operator of the vehicle and is arranged so that no reorientation of the machine with respect to the felled trees is required.
