Abstract: ABSTRACT OF THE DISCLOSURE             A machine is set forth for forming a sleeve of shrinkable, cellular polymeric material from a pre-decorated web.  The machine includes providing a web of material of predetermined width, the web being advanced by a feed drum which is rotated on a vertical shaft with a vacuum means on the drum for holding the web thereon.  The feed drum shaft for driving the drum has means for providing at the surface a velocity greater than the web velocity, the vacuum means providing a switch clutch effect for maintaining the web length in tension.  A rotary knife is provided which is engageable with the web on the drum for cutting the sleeve blank from the web. A mandrel turret machine is provided which has a circular array of rotatable mandrels, each mandrel being mounted on a rotatable vertical shaft with the turret being rotatable about a vertical axis and whereby the surface of the mandrel is moved successfully in tangential proximity to the surface of the feed drum at a transfer station.  Means are  provided at the transfer station for rotating the mandrel through a winding cycle in excess of one revolution with vacuum means being provided on each mandrel for engaging a leading end of a sleeve blank on the feed drum and transferring it to the mandrel, the sleeve blank being wrapped around the mandrel in the winding cycle overlapping the trailing end of the leading end thereof.  A heat sealing device is provided on the turret individual to each mandrel for applying hot air onto the adjacent surfaces of the overlapping leading and trailing edges of the blank sufficient to join the overlapping surfaces and to form a seamed sleeve.  Stripping means is provided on the mandrel which at least partially encircles the mandrel and operated in response to the rotary movement of the turret beyond the sealing station for axially stripping the sleeve downwardly from the mandrel to produce a sleeve.  The sleeves so produced are useful for overlying the neck of a closure to provide a pre-decorated label which provides a pilfer-proof seal.

Abstract: Abstract A high sensitivity, low noise, broad bandwidth channel conduction field sensor device is described.  The conductive channel is configured to create an exceptionally narrow, un-depleted conduction channel of approximately filamentary form.          The filamentary conductive channel so formed is provided with a source at one end of the channel and two or more laterally spaced drains at the other end thereof.  Electric or magnetic fields may be utilized to deflect a stream of charge carriers traversing the conductive channel from the source toward the drains utilizing the depletion width modulation effect of the fields upon the boundaries defining the conductive channel portion.  Modulation of the depletion zone width and depth along the channel sides effectively moves the stream of carriers and the conductive channel area to overlap one drain more than another.  This develops a differential drain current balance which can be utilized to provide an output signal.  Width and length criteria for defining a filamentary channel structure are described for the ultimate desired configuration and size which are to be obtained.  As noted, operation of the device is based upon modulation of the width and depth of the deple-tion zone boundaries defining the conductive channel.  An increased signal output is obtained by reducing the width of the channel to eliminate excess carriers normally found in wide channel devices and, further, by making the depletion zones as large a portion of the total channel width as can be obtained.

Abstract: RCA 68,004 TIME BASE ERROR CORRECTION SYSTEM                 Abstract of the Disclosure Means are provided for detecting departures of the relative velocity between a signal pickup and the information track of a video disc from a predetermined value.  Signals recovered when relative motion is established between the track of the disc and the signal pickup are subjected to a delay in a charge transfer delay line. The line delay is made to vary in response to the output of the detecting means so as to compensate for signal time base errors engendered through departures of said relative velocity from the predetermined value.  Non-linearities of the time delay of the delay line with respect to the output of the detecting means, which are due to large changes in the output frequency of a voltage controlled oscillator utilized for controlling the operation of the delay line, are compensated for by means of a linearizing feedback loop for the oscillator.

Abstract: Abstract A quickly adjustable ratchet wrench is essen-tially a crescent wrench modified by eliminating the ad-justing screw and substituting a locking member and z lever to engage and disengage the locking member with the rack on the movable wrench jaw.  A tension spring lightly biases the movable jaw toward closed position. With the locking member disengaged from the rack, the movable jaw may be manually opened, and when the movable jaw is released the light spring bias closes the jaws on a bolt head.  when the wrench jaws are engaged with a bolt head, rotation of the lever arm against the wrench handle engages the locking member with the rack to turn the bolt, while rotation of the lever arm away from the handle disengages the locking member and per-mits the jaws to open against the light spring bias and slip over the angles of the bolt head; thus eliminating the need to remove and replace the wrench on the bolt head.
