Abstract: A drier comprises a plurality of structurally independent drying chambers in each of which a respective climate, which does not interfere with that of the other chambers, is created and controlled. The chambers, each of which is equipped with its own conveyor for pasta-holders, are connected by tunnels in which devices transfer the holders from one chamber to another.

Abstract: A security seal has an elongated flexible strap integral with a housing at one end. The other end of the strap can be moved through a passageway in the housing to form the strap into a closed loop. Facilities in the housing and on one surface of the strap permit movement of the strap out of the passageway and prevent reverse movement of the strap if the strap is properly inserted without a half-twist and into the proper end of the passageway. These facilities are ineffective to prevent reverse movement if the strap is improperly inserted. The seal is improved by forming a groove longitudinally in the passageway. A surface feature on the other surface of the strap is conformally received in the groove when the strap is properly inserted into the passageway without twisting. If the strap is improperly inserted, the passageway interferes with and applies force to the surface feature. This force discolors or deforms the surface feature to provide a visual indication of improper insertion.

Abstract: A process and apparatus for drawing polyamide yarn in which the yarn having a lubricating finish is drawn while being spirally advanced in frictional contact with the outer surface of a yarn draw assist element. In such process and apparatus, the outer surface of the draw assist element moves at a speed at least 100 times slower than the speed at which the yarn is advanced. From the draw assist element, the yarn directly advances to a roll initial contact location on a pair of space-apart heated rolls and spirally advances on the rolls through at least one wrap in contact with the outwardly-facing surfaces of the heated rolls. The distance that the yarn spirally advances longitudinally in the wrap can be said to define the wrap advance on the rolls. The roll initial contact location of the heated rolls is oscillated by moving the outer surface of the draw assist element in relation to the pair of heated rolls to oscillate the wrap on the rolls a distance which is at least equal to the wrap advance.
Abstract: An anti-theft device that is adapted to be connected adjacent to or on a battery of a motor vehicle and including a power switch for disconnecting the battery from its standard battery cable when current flowing through the cable exceeds a preselected substantial amount of current associated with an attempt to start the vehicle. A lockout circuit is actuated by a remote transmitter for generating an external command signal to override the operation of the power switch. This device can be attached directly to a battery without external wiring and still provide the passive or self-arming anti-theft device.

Abstract: A bearing halfshell for internal combustion engine connecting rods with its inner surface having a substantially constant radius of curvature from a central plane of symmetry to two portions of the inner surface located one on each side of the central plane of symmetry and on a corresponding radial plane. The radial plane forms an acute angle .alpha. with a bearing parting plane, the remaining end portions of the inner surface from the radial plane to the end of the bearing being defined by surfaces with extra relief so that the bearing thickness gradually decreases away from the central plane of symmetry in an accentuated manner as compared to the constant radius of curvature of the inner surface. Thereby, two chambers are formed in the end portions, with an eccentricity .epsilon., of the inner surface ensuring a stable film of oil between the bearing halfshell and a corresponding shaft, and reducing the operating temperature of the bearing halfshell.

Abstract: The invention is directed to a tape cassette winder/rewinder adapted to wind on rewinder a conventional VHS tape cassette or a compact VHS-C type cassette. This is achieved by providing a space to receive the conventional VHS tape cassette and a recess below this space to house retractable confining arms that extend to hold a VHS-C tape cassette. The recess also houses a retractable idle gear assembly which extends to drive the take up reel of the VHS-C cassette when it is being held by the confining arms.
