Abstract: BEAD CONSTRUCTION FOR A HEAVY DUTY PNEUMATIC TIRE         ABSTRACT OF THE DISCLOSURE           A heavy duty pneumatic tire is provided with bead cores of symetrical or asymetrical polygonal cross-sectional configuration.  Extending radially outwardly therefrom are apex strips of a hard rubber compound which contact the bead cores along their radially outwardly oriented faces.  The apex strips have a width at least as great as the width of the bead cores measured in a selected direction, and have a height of not more than 1.5 times the width of the bead cores.  The terminal ends of turnups formed by wrapping a carcass ply radially about the bead cores, and reinforce-ment strips are enveloped in cushion elements of a rubber material which are softer than the carcass ply and the apex strips   The apex strips have a markedly compact shape cross sectionally and form with the bead cores, rigid units through which stresses occurring in the carcass during tire operation can be transferred.  Residual forces in the turnups and the reinforcement strips can be absorbed readily by the cushion elements to reduce the occurrence of fatigue cracks in the beads.

Abstract: ABSTRACT  OF  THE  DISCLOSURE          Apparatus for measuring the temperature of a surface of an article includes a thermally-responsive temperature measuring element for providing an output signal related to the temperature of said element.  A pair of electrical conductors support the temperature measuring element in a position spaced from a supporting member and close to but spaced from the surface so that the element is responsive to the temperature of the surface.  The electrical conductors transmit the output signal from the element, and are exposed to the same temperature as the element.  Thus, no temperature gradient exists between the element and the electrical conductors, and heat escape from the element to the electrical conductors is eliminated.

Abstract: Abstract of the Disclosure Method and device for eliminating the background brightness vari-ation of a video signal, in which the background brightness in each line of the frame of a video signal has its low frequency brightness signal a(t) limited, as well as being limited by its deviation from the limited bright-ness of the preceding line of frame.  This can be expressed mathematically by stating that ¦V(t-) - ?(t)¦ is minimized by means of ?(t) on the marginal conditions ¦ ?(t) - ?(t - T)¦ ? .epsilon. and ¦ ?(t) - ?(t - .DELTA.)¦ ? .epsilon., in which V(t) = the video signal V at the moment t; a(t) = an estimation of the background brightness variation a(t);      T    = the duration of a line; .DELTA.    = h/b T/k, in which h/b = the height/width ratio of the image and k = the number of lines per frame, and .epsilon.    = the maximum value of the derivative of a(t) multipled by .DELTA.. Thus the device of this invention comprises a device for limiting the rate of the build-up of the video signal current during each line by means of a slope limiter comprising a current limiter and condensor connected to the video signal, a delay circuit for delaying the resulting limited current for the duration of one line of the frame comprising a delay and a one-to-one amplifier so that the difference between the limited variation can be limited with respect to the preceding line in the frame, and a subtracting device for subtracting this difference from that of each line of the original video signal.  Since the first line of each frame has no preceding line by which to be limited, a separate prolongation device is provided responsive to the frame synchronization pulse for inactivating the difference limiting device for the first line of each frame.  In known methods, use is made only of a small length of the line that is being scanned at a certain moment unlike the present invention.

Abstract: COUNTER-ROTATING VORTICES GENERATOR FOR AN AIRCRAFT WING       ABSTRACT OF THE DISCLOSURE         A device for enhancing the lift capability of an aircraft wing is characterized by at least one forwardly projecting finger member mounted on the leading edge of the wing.  The finger generates counter-rotating vortices, each in contact with the other, trailing backwardly across substantially the entire upper surface of the wing behind the fingers as the airflow moves upwardly and around the lateral edges of the finger.  As the counter-rotating vortices trail backwardly over the upper surface of the wing, a blockage effect is created and the airflow patterns across the wing are modified to produce an increase in lift.

Abstract: Abstract A machine for injecting fluids into meat products or the like is disclosed comprising a table having a conveyor mounted thereon adapted to convey the meat product from one end to the other. A pair of reciprocating arms are pivotally connected at one end thereof to opposite sides of the table. An electric motor is operatively connected to the reciprocating arms to move the reciprocating arms upwardly and downwardly with respect to the conveyor.  A fluid manifold apparatus comprised of a plurality of fluid manifolds is rigidly secured to the other ends of the reciprocating arms and extends therebetween across the table transversely to the direction of travel of the meat product.  Each of the manifolds has a plurality of injector needles extending downwardly therefrom which are adapted to pierce the product and inject fluid thereinto while the needles are embedded within the product.  Each of the fluid manifolds is in operative communication with a displacement pump which is in communication with the source of fluid to be injected. A stripper plate is secured to each of the fluid manifolds and moves vertically downwardly with the fluid manifold until it engages the product to sense the thickness of the product. The fluid manifold continues to move downwardly or overtravels with respect to the stripper plate after the stripper plate engages the meat  product. An actuator arm is pivotally connected to each of the stripper plates to actuate a valve imposed between the displacement pump and the fluid manifold during the overtravel movement. Each of the displacement pumps includes a movable piston which is operatively connected to a cam mounted on the shaft which imparts the reciprocable movement of the reciprocating arms so that the displacement pump is actuated to coincide with the vertical velocity or harmonic motion of the fluid manifold.

Abstract: ABSTRACT OF THE DISCLOSURE:           Device enabling the direct measurement of the overall insulation level of an acoustic insulation medium with respect to a reference excitation noise signal when said medium is subject to an actual excitation noise signal deviating from the reference excitation noise signal.  The device comprises two microphones receiving a first and a second alternating signals respectively representing the noise signal actually transmitted through the medium and the actual excitation noise signal and a read only memory storing spectral components of the reference excitation noise signal in a plurality of given spectral bands.  The first and the second alternating signals are decomposed into alternating spectral components in these spectral bands and the alternating spectral components of the second signal are rectified in order to obtain rectified spectral components.  These rectified spectral components are added to the alternating spectral components of the first signal relating to the same spectral bands thereby obtaining composite signals each having a direct and an alternating component.  These composite signal are selectively passed through attenuators thereby forming attenuated alternating spectral components and attenuated rectified spectral components which are separated from each other.  The attenuated rectified spectral components are compared to the spectral components of the reference excitation noise signal relating to the same spectral bands and thereby error signals are obtained respectively corresponding to the spectral bands, and these error signals control the attenuators.

Abstract: THIN FILM MAGNETIC HEAD                      ABSTRACT   A thin film magnetic transducer comprises a non-magnetic substrate and a pair of magnetic pole pieces having different widths.  The width of the first pole piece deposited on the substrate is greater than that of the second pole piece to prevent a problem asso-ciated with misregistration between the pole pieces, which may occur during manufacture.  Such misregis-tration generally results in a "wraparound", so that the edge of the second pole piece would have an ex-tended portion forming an angle to the normal magnetic transitions created by the pole pieces.  The width of the second pole piece is slightly less than the ef-fective width of the data track recorded on a magnetic medium, and the data track width is  relatively in-dependent of the dimension of the first pole piece.
