Abstract: 1063,002                     PRESS CONTROL SYSTEM      ABSTRACT OF THE DISCLOSURE A continuous feed stamping machine, press or the like, has a control system for automatically stopping the machine in the absence of material to be stamped. The control system includes a normally closed limit switch which is held open by the presence of material to be stamped. After each stamping operation as the stamped product is released from the die area, the limit switch returns to its normally closed position. If the limit switch is not opened by the feed of more material, within a predetermined time interval, the machine is stopped. The time interval is related to the operating frequency of the machine such that in the absence of material the machine will be stopped before the machine is damaged. The control system, whichmay operate in either the astable (oscillating) or monostable (one-shot) mode, effects the charging of a capacitor when the limit switch closes, and the capacitor discharges when the limit switch opens. If the limit switch is not opened by the feed of new material, within the preselected time interval, the charging of the capacitor above a threshold voltage causes the machine to be stopped.

Abstract: ABSTRACT OF THE INVENTION A thin-walled, one-piece plastic tank for subterranean storage and transmission of sewage or other materials.  The tank comprises a bottom wall, an arched top wall and opposed end walls.  The top wall is sub-stantially semi-circular in cross-section with a plurality of corrugations therearound.   Along the apex area of the arch is a pair of manhole-like openings with an arced strengthening rib therebetween.  The bottom wall is generally arced in cross-section with a radius very large compared to the radius of the cross-section of the top wall which causes the bottom wall to be generally flat.  The end walls are arced in the longitudinal, cross-sectional and horizontal planes.  The end walls each have a plurality of corrugations.  In the root of one of the corrugations is a depression which contains a horizontal aperture for the egress or ingress of fluid materials.  The bottom wall has a plurality of corrugations mating with the top wall corrugations such that the corrugations circumscribe the tank.  Further, the bottom wall has a pair of regions one adjacent each end wall which contain a plurality of triangular inden-tations in a truss-like configuration.

Abstract: ABSTRACT OF THE INVENTION     There is disclosed a gas turbine having an air compressor at its input and followed by a gas diffuser and primary and secondary combustion chambers; the primary combustion chamber has a rotating inner wall driven by vanes at the output of the secondary combustion chamber; these vanes also drive the compressor at a higher speed through a gear train; the gas diffuser directs air into the primary combustion chamber and also directly into the secondary combustion chamber by means of a rotating nozzle; a turbine output wheel is driven by the exhaust of the turbine.  Rotation of the inner wall of the primary combustion chamber provides more efficient combustion due to improved fuel atomization and a more homogenous fuel-air mixture than in known turbines.  In addition, the provision of a secondary combustion chamber, which is heated by the exhaust gases of the primary combustion chamber, increases combustion in the secondary chamber and, thus, improves the overall efficiency of the turbine.

Abstract: ABSTRACT   Method and apparatus for inverting a toroidal article, such as a tractor tire, comprising:  a base assembly; a first frame assembly pivotably rearwardly attached to the base assembly; a second frame assembly pivotably attached to a forward portion of the first frame assembly; a tire holder attached to the second frame assembly; and grappling means for holding an edge portion of a tire to be inverted relative to the base assembly.  The tire holder is rotatable to permit the removal of a rim portion of the tire on the tire holder by a cutting blade fixed on a boom attached to the apparatus.     Rotation of the tire holder is actuated by a hydraulic motor, and hydraulic cylinders are used to pivot the first frame assembly and the second frame as-sembly.  The apparatus is made portable, with a minimum of necessary external support systems, such as a hydraulic fluid pump.  The article thus has a generally cylindrical shape, smoothed by clamping means, making it useful as a feed bunk for livestock.

Abstract: ABSTRACT          The invention relates to a method for automatically measuring aiming errors and correcting aiming values in the aiming and firing of ballistic weapons and to an apparatus implementing this method.  A fire control device supplies continuously the azimuth and elevation of a target position measurement corrected for daily influences and superelevation, the gun aiming values and the instantaneous time of flight of the projectile.  The corrected azimuth and elevation values of the target are compared with the aiming values after these values have been stored for a time corresponding with the time of flight or a fraction of the time of flight.  The results of this comparison are used for correcting the gun aiming values.

Abstract: IMPACT WRENCH MECHANISM AND PIVOT CLUTCH THEREFOR     ABSTRACT OF THE DISCLOSURE     This invention pertains to a rotary impact tool and a clutch therefor, wherein a motor drives a carrier cage or member within which is pivotally mounted one or more swinging hollow hammer members. An output shaft extends through the carrier member and through the hollow hammer member and includes forward and reverse impact anvil surfaces.  The hammer member is, or members are, mounted to swing in respect to the carrier member as the hammer member(s) rotate(s) with the carrier member, and carries forward and reverse impact jaws on its internal surface.  As the clutch is driven in the forward direction by an air motor or the like, the forward impact jaw is moved in and out of the path of the anvil jaw on the output shaft by cam action, and during an impact blow the inertia of the rotating hammer member(s) act automatically to hold the impact jaw in engagement with the anvil jaw.

Abstract: TENNIS RACKET            ABSTRACT:         A tennis racket comprises dynamic weights (6) distributed symmetrically relative to the longitudinal axis of the racket between the throat and the transverse axis of the head and suspended by arcuate straps (7) glued to the racket frame (2), the weights being displaceable in a direction perpendicular to the plane of the stringed area (3).  The combination of weights and straps is adapted for having an intrinsic vibration frequency about 1.4 to 2 times the fundamental vibration frequency of the racket, such that when the weights are vibrated at their intrinsic frequency (by a ball striking the racket), the vibration of the racket is damped by energy transfer to the weights, and yet energy is also returned to the racket as a reaction in the direction of the ball's flight before -the ball leaves the racket.  The angular stability of the racket is improved over either fixed weights or dynamic weights having frequencies outside the critical range.

Abstract: ABSTRACT OF THE DISCLOSURE     A torque-transmitting drive having a driving member and a driven member spaced therefrom with an endless transmission belt engaging the members to transmit torque from the driving member to the driven member.  The endless belt is folded over one of these members such that two strands of this belt pass over the one member and this same one member thereby does not pass through the endless belt.           A bearing sleeve is further slippingly mounted on this one member, over which the endless belt folds such that one strand of the belt at the fold passes over the bearing sleeve.  Thus, one strand at the belt fold is in driving engagement with the member and the other strand of the endless belt mover in the opposite direction such that the bearing sleeve is rotating in a direction opposite to that of the member over which the belt folds.  When replacing belts, it is not necessary to disturb or dismantle the member over which the endless belt folds, as that member does not pass through the belt.                            1.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus which develops a latent image by transporting a conductive developer material compris-ing marking particles into contact therewith successive times.  During the first contact time, the conductivity of the developer material optimizes development of solid areas within the latent image with marking particles. The last contact time occurs with a developer material having a lower conductivity than the development material employed during the first contact time.  In this way, development of lines within the latent image with marking particles is optimized during this latter contact time.
