Abstract: ABSTRACT     A structure useful in playing a game in which a tethered ball is repeatedly being engaged can be constructed so as to utilize a hinged member connecting a tether for the ball to an upright support mounted on a base.  The hinge member is preferably constructed as a unitary body out of a resilient, elastomeric material such as a natural or synthetic rubber so as to include ends which are sufficiently large and massive so as to be incapable of bending connected by a flexible portion shaped so as to permit bending between the ends of the hinge member and so as to permit the ends being twisted relative to one another no more than about 90 degrees when the ends are located so as to be in alignment with one another.  The flexible portion also permits twisting between the ends of the hinge member when the ends are not located in alignment with one another.  This hinge member serves to control movement of both the tether and the ball carried by the tether so as to provide that the ball may be moved in more or less the manner in which a ball is hit back and forth across a net in a conventional net type game such as tennis, ping pong or the like.

Abstract: CARBURETOR          Abstract of the Disclosure A carburetor for an internal combustion engine.  A carburetor body has an induction passage for air to be drawn into the engine.  A throttle valve is positioned in the induction passage and is movable between an open and a closed position to control the quantity of air drawn into the engine.          A staging valve is positioned in the induction passage and is movable between an open and a closed position.  The staging valve is closed during engine cranking and is moved to a first open position when the engine starts and toward its fully open position as the engine warms up.  The opening movement of the staging valve is limited to a second open position which is less than its fully open position.  The limiting of staging valve movement to this second and less than fully open position limits the usable air capacity of the carburetor to less than its maximum capacity.  Staging of the carburetor occurs in response to movement of the throttle valve past a predetermined open position and the staging valve is allowed to move freely between its second open position and its fully open position soley in response to the demand for air by the engine.  The free movement of the staging valve to its fully open position increases the usable air capacity of the carburetor to its maximum capacity.

Abstract: ABSTRACT OF THE DISCLOSURE                A disposable carton formed of low cost material and adapted for the packaging of eggs and the like is formed with coacting elements of a cover and latching flap which, in combination, afford rigidity to those elements, guide the coacting elements on closure and provide for a secure latching susceptible of easy opening. Recesses are provided in the cover and latching flap for guidance and rigidity.   Latching is accomplished by a recess extending inwardly from the cover front wall to engage the underside of a latching bar of the flap, which is positioned above a substantially rectangular shaped recess in the latching flap.  The carton is particularly characterized in that it exhibits improved resistance to crushing when other cartons are stacked upon it.  This crush resistance is imparted to the carton by employing integrally molded cover support ribs which are positioned immediately above and adjacent to the locking recesses on the latching flap.  Such an arrangement allows the upper edge of the locking aperture on the carton front wall to bear against the cover support ribs for additional support and to withstand crushing forces which may be applied to the carton cover.

Abstract: ABSTRACT       More than 60 % of the heating value of the fuel con-sumed in the usual internal combustion engines is wasted past remedy. The present invention, which is applicable in combination with any kind of internal combustion engine, and especially with fuel injection engines of the compres-sion-ignition and of the spark-ignition types, is intended to reduce the heat losses and to improve the thermodynamic cycles by making practicable the increase of the compres-sion ratio. Besides, a reduction of the emission of pollu-tants is achieved.        The invention embodies various energy saving systems including: apparatus to generate superheated pressure steam, an injector-compressor apparatus utilizing the generated steam as motive power and serving to pre-compress the com-bustion air, a jacketed cooling system of the engine through which the compressed air-steam mixture delivered by the in-jector-compressor flows serving as a coolant, said mixture being thereby conveniently superheated and being rammed into the engine's combustion space by virtue of its pressure, and a feasibly complete thermal insulation system.       The invention offers the advantage of reducing the usual heat losses to the only heat being rejected with the cooled exhaust gases.

Abstract: 41                47, 560 ABSTRACT OF THE DISCLOSURE The  signal to-noise  ratio  of  a  signal  to be transmitted  through  a  communication  channel having  an upper and a lower limit in magnitude is sampled digitally and a common corrective factor for the deviations about the mean value of the signal is determined for amplifying the  low  portions  of  the  signal  without  exceeding the limits.  By a reverse process at the receiving end of the communication  channel,  the  signal  is  returned  to  its original amplitude, thus reducing any noise superposed in the transmission.          The invention is applicable to a video channel where  the  sampled  signal  is an audio signal.  In such case, the deviations of the samples about the mean of the digital information of the audio signal are matched with the mean of the video channel between the black level and the maximum white level.

Abstract: ABSTRACT ln a machine for cement lasting side portions and the heel seat of shoes, the side portions are lasted by lasting rolls and the heel seat by wiper plates. For applying adhesive, each lasting roll has an associated nozzle which applies adhesive progressively in advance of its associated lasting roll. Furthermore, when the lasting rolls reach the point of termination of side lasting, they remain in pressing engagement with the shoe bottom, but their rotation is terminated, and in this condition the nozzles continue to apply adhesive in the heel seat region. This may be achieved by merely discharging adhesive from the stationary nozzles and allowing it to run into the heel seat, or alternatively the nozzles may track bodily into the heel seat. Thereafter, the lasting rolls and nozzles are retracted and heel seat wiping can take place. The invention may also be incorporated in a machine in which the whole of the shoe bottom is lasted.

Abstract: ABSTRACT            "Diagnosis of Engine Lubricant System"     This disclosure relates to a system for analyzing the performance of a reciprocating piston, internal combustion engine such as a diesel engine.  Sensors are connected to the engine, which respond to various operating parameters, and signals representing the parameters are fed to computer processing equipment.  Two of the parameters are the lubri-cant system pressure and the engine speed.  To test the lubricant system, the engine speed is stabilized at maximum governed speed and then the fuel supply to the engine is quickly cut off.  The lubricant system pressure and the engine speed data are sensed and processed as the engine decelerates, the processing including a comparison of the pressure-speed characteristic with a standard or reference characteristic.
