Abstract: ABSTRACT:         A drive mechanism for a reciprocating and mul-tiple step index mechanism to achieve smooth starting and stopping action with controlled acceleration and de-celeration.  It is characterized by extremely flexible kinematic characteristics achieved by the superposition of a constant velocity, fundamental and higher harmonic component.  The mechanism utilizes pairs of rotating drive members and eccentric members mounted in non-rotational relation, the pairs being connected to rotate in a multiple integral angular velocity ratio.  An out-put member is arranged in driving relation to one of the eccentric members and is influenced also by the rotation of the other eccentric member.  Power input is directed to one of the pairs of drive members.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved liquid-dispensing nozzle and more specifically, an improved vapor recovery means for a nozzle comprising a vapor collector (such as a flexible bellows) surrounding a portion of the discharge spout in spaced relation thereto, one end of which is sealed to the upper portion of the spout; and at the other end of the vapor collector, a compressible cellular plastic material such as foamed plastic associated therewith.  When the discharge spout is inserted into, e.g., an automobile fillpipe, the compressible cellular plastic material forms a vapor seal with the upper end of the fillpipe whereby the vapors escaping from the fillpipe are directed into the interior chamber formed between the exterior of the discharge spout and the inside of the vapor collector thereby minimizing the escape of vapors to the atmosphere.  The vapors are then removed from this chamber.  The compressible cellular plastic material may be made from an elastomer selected from the group consisting of (1) polyacrylate elastomer, (2) acrylonitrile containing elastomer, (3) epoxy derived elastomer and (4) fluorine containing elastomer.

Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus is provided to apply pulling forces from any direction from any elevation around a vehicle being repaired and/or serviced.  The apparatus is arranged so personnel using it are concerned with minimal physical lifting movements and minimal setup arrangements of the apparatus.  Each embodiment of the apparatus utilizes at least one tower assembly equipped with an elongating subassembly to move a tension member, through directional change devices, as it remains secured to some portion of a vehicle, thereby undergoing at least one repositioning pull in a direction opposite to at least one prior force that previously caused some of the damage and/or misalignment.          Depending on the magnitude of the restoring force required, the tower, other towers, and/or other structures may be secured together and/or to the vehicle as well, to create a firm basis for anchoring the apparatus and/or the vehicle as one or more reactive forces are controllably created.          Depending on the anticipated use of the apparatus and the capital expenditures to be made, the apparatus is made available in different embodiments, ranging from a sole location of a tower to multiple locations of several towers related to overall reactive structures and/or vehicle ramps serving as mutual multiple holding or anchoring places of forces applied to the vehicle, as the elongating subassemblies of the towers are moved to create the restorative pulling forces.

Abstract: ABSTRACT OF THE DISCLOSURE: In a receiver of a transmission system for binary pulse signals whose DC level is disturbed during trans-mission, an accurate correction of the disturbing DC com-ponents is obtained even for pulse signals deviating considerably from the nominal transmission speeds and peak values, by using a correction circuit having two parallel branches between input and output.  The first branch includes a capacitor between input and output and the second branch includes a peak detector and a comparator which co-operate for generating a binary decision signal which is applied to the output via a resistor.  The AC com-ponents of the pulse signals are only passed through the first branch and the DC components inherent in the pulse signals are only passed through the second branch.
