Abstract: A baby bottle top assembler automatically assembles nipple, collar and hood cap components into a unitary structure. Nipple, collar and hood feeders serially supply the cap components to pickup points. The feeders each include a hopper for holding the cap components, a conveyor for removing the cap components from the hopper and a magazine assembly for serially feeding the cap components to the pickup points adjacent the assembly wheel. Pickup pins pass the pickup points and first engage a nipple, then a collar and finally a hood. The components are snapped together into a unitary structure by a pinch roller. The unitary nipple/collar/hood assembly is removed from the pickup pin by an assembly stripper having fingers which engage under the nipple/collar/hood assembly forcing it off the pickup pin.

Abstract: Electrical sockets used for mounting integrated circuits and the like are assembled by sequentially feeding electrically insulative bodies onto a track between a pair of endless belts which transmit motion to the bodies forcing them to move along a first path which extends beyond the belts. The socket bodies typically are provided with two parallel rows of contact receiving apertures which extend through the bodies from the top surface to the bottom surface thereof. A continuous carrier strip having spaced contact elements depending therefrom is directed along a second path which tangentially meets the first path so that the contact elements are sequentially received in one of the two rows of contact receiving apertures. The contact elements are securely seated by means of a seating roller and are then staked in position by one or more staking rollers after which the contact elements are severed from the carrier strip.

Abstract: Measuring apparatus for determining the position of a point in a measuring volume relative to a datum point at which three mutually perpendicular axes intersect, includes a probe member supported for movement within that volume. Errors due to rotations about the various axes are corrected by providing additional transducers on each axis, there being (n+1) transducers where n is the number of rotations for which correction is required. The embodiments described have three X-axis transducers X.sub.1, X.sub.2 and X.sub.3 and three Y-axis transducers Y.sub.1, Y.sub.2 and Y.sub.3 which, with the appropriate circuitry correct for pitch and yaw errors about the two axes. For the Z-axis only two transducers, Z.sub.1 and Z.sub.2, are required. The circuit means combines the various transducer outputs to derive corrected values of the three co-ordinates.

Abstract: A scaling device employs a first, outer cylinder, a longitudinal scale having detectable indicia thereon, and a second cylinder of lesser diameter than the first cylinder but of greater diameter than the radial extent of the scale. The cylinders and the longitudinal scale are disposed coaxially, with the scale affixed at one end thereof to an end cover plate in one end of the first cylinder. The second cylinder is journalled in a bearing in an end cover plate in the other end of the first cylinder for axial movement relative to the first cylinder over the longitudinal scale. A scale detector element is disposed at one end of the second cylinder to detect indicia on the scale and to generate scale signals in response to longitudinal relative displacement of the first and second cylinders. A third cylinder affixed to and disposed within the second cylinder defines an annulus between the second and third cylinders through which leads from the detector element can extend.

Abstract: The invention contemplates a so-called switching probe head in which the movable element of the probe has a tensed at-rest position on support structure which determines its zero position and from which it is displaced upon work contact.To increase the accuracy by which the zero position of the probe element (2, 4) is reproduced, the probe element is suspended, without friction, from a housing part (1) of the probe head, via at least three filaments (5a, b, c), wires or flexible strips. For torsionally rigid centering of the probe element, friction-free wire or strip arrangements are also usable; and torsional-rigid alternatives include use of a bellows (3) or of balls having rolling contact with opposing walls of centering grooves.

Abstract: A probe for sensing the position of a workpiece comprises a housing adapted to be secured to a coordinate measuring machine. A stylus projecting from the housing is engageable with the workpiece for sensing the position thereof. The stylus is secured to a moveable member supported within the housing by three bellows having mutually perpendicular axes and each secured to the moveable member and the housing in position therebetween. Since a bellows is inherently stiff in torsion about its axis but is flexible axially and transversely, the bellows cooperate to constrain the stylus for parallel motion. More particularly, any one first bellows can expand or contract to accommodate movement of the stylus in the direction of the axis of that the first bellows, a second one of the bellows prevents tilting of the stylus by virtue of its torsional stiffness. At the same time both the second and third bellows flex transversely to accommodate the expansion or contraction of the first bellows.

Abstract: The disclosure relates to techniques for high efficiency drying of wet-processed tubular knitted fabric. The wet tubular fabric is initially spread to flat form and then guided in a controlled manner over a so-called Mach nozzle, at which high velocity gaseous medium, usually steam, at speeds approaching the speed of sound and above, is discharged directly through the fabric, which is maintained in tension as it passes over the nozzle outlet. The thus treated tubular knitted fabric, now with a greatly reduced liquid content, is then immediately directed over a second spreader device, which distends the fabric widthwise to a predetermined, uniform width, to restore the fabric width lost during wet processing and during the relatively high tension nozzle treating operation. In this damp, geometrically stabilized condition, the fabric may be directed immediately into an otherwise conventional tensionless dryer for tubular knitted fabric, where the necessary final drying operations are completed.
