Title: Tamper indicating closure
Inventor: GREGORY JAMES L
IPC: B65D41/34
Filed: 1987-06-26
Granted: 1991-11-05
Abstract: ABSTRACT         A tamper indicating closure for a container comprising a threaded cap to which is attached an indicator ring.  The indic-ator ring has a radially inward lower flange that slips into locking engagement with a flange on the neck of the container as the closure is applied to the container.  As the closure is removed from the container, the indicator ring is severed along weakened portions so that the lower portion of the indicator ring drops clear of the closure thus providing an indication the closure has been rotated in a direction for its removal from the container.

Abstract: D.1121 DISASSEMBLABLE BALL AND SOCKET JOINT  Dominique DONY and Jacky HUMBLOT         ABSTRACT OF THE DISCLOSURE       The invention relates to a disassemblable ball and socket joint, of the type positioned by a single opera-tion.  The ball carried by a journal enters a hemispherical housing of the ball cage, a c-shaped retaining ring partly surrounds the cage an penetrates its wall through two slots which lead into the introduction channel of the ball into its housing, converging outwards.  To avoid corrosion risks and to facilitate disassembly, the ring exerts upon the cage a force parallel to the axis of the channel at two points located on either side of the plane of symmetry in the summital region, and it also urges the interior face of the slots, by virtue of proturberances provided near its ends, for example, so that it is not normally in contact with the ball or its journal.

Granted: 1993-07-27
Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus for controlling the posture of a front loader which has booms attachable to a vehicle body which are pivotally  movably  upward  and  downward  and  has  a  work implement attached to the forward ends of the booms and pivotally movable in a scooping direction and a dumping direction,  Each of the booms and the implement are pivotally movable by a single control lever independently of each other or  movable  simultaneously.    The  apparatus  includes  an actuating member for shifting the control lever from a boom raising position to a boom raising and dumping position when the booms are not positioned lower than a specified level.   This eliminates the likelihood of the implement tilting rearwardly downward even if the booms are raised, precluding the implement from spilling the earth or sand scooped up.

Title: Process for applying reinforcing material to a diaper cover material
Inventor: WITTROCK MARVIN E
IPC: B31B1/90
Filed: 1988-08-26
Granted: 1991-11-05
Abstract: ABSTRACT      A technique for adhering individual patches of substrate material to spaced-apart regions of a moving web layer comprises a transporting mechanism for moving the web layer and a supplying mechanism for providing a selected substrate material.  An applicating mechanism deposits a selected coating of hotmelt adhesive onto the substrate material, and a regulating mechanism automatically maintains a selected cross-directional registry between the substrate material and the deposited coating of adhesive.  The coated substrate is cooled, and a directing mechanism engages the coated substrate to feed it to a separating mechanism at a selected rate.  The separating mechanism segments the coated substrate into individual patches.  A phasing mechanism provides a selected spatial segregation between the individual patches, and an assemblying mechanism adhesively secures the segregated patches onto selected spaced regions of the moving web layer.  An indexing mechanism selectively displaces the coated substrate material from the separating mechanism when the directing mechanism is disengaged from the substrate material.

Abstract: The invention relates to the preparation of fruit for use in packaged dry foods, such as mixes and ready to eat cereal.          A method of infusing high levels of liquid humectant into fruits such as raisins, without generating a stream of waste humectant, is disclosed. The method comprises applying a relatively high level of liquid humectant as a surface coating, and allowing the raisins to stand for enough time for most of the humectant to be absorbed into the fruit, before admixing the resulting fruit the dry food for packaging.            For dry foods having very low Water Activity levels, e.g.          .30 and below, special means are disclosed for increasing the liquid humectant carrying capacity of the fruit, in order to accommodate very high levels of liquid humectant as a topical application, for infusion during a period of time in which the raisins are standing, e.g. during storage or shipment.  These means include mechanical means, such as tumbling, or alternatively, ingredient means, such as the use of humectants containing thickeners.
