Patent GB-2175848-A (GB)
Title: Non-occluding, liquid-impervious, composite backsheet and use thereof in an absorptive device
Inventor: LINMAN ELMER KELLY
IPC: A61F13/15
Filed: 1986-05-30
Abstract: A backing for an absorptive device such as a disposable diaper or a sanitary napkin, said backing comprising a combination of two layers. The first layer which does not contact the wearer's skin is preferably comprised of a liquid-impervious layer of polymeric film or the like. The second layer is also preferably comprised of a polymeric film which has been made pervious to liquid by providing a multiplicity of relatively small proturberances, each ending in an aperture, substantially across its entire surface. The apertured protuberances, which resemble a tiny volcano in cross-section, exhibit a soft, highly consumer preferred tactile impression which is sometimes characterized as «silky». In backsheets of the present invention, the second layer is oriented so that the tiny volcano-like cusps of the second layer constitute the exposed portion of the backsheet. This minimizes the area of contact between the backsheet and the wearer's skin. In a particularly preferred embodiment of the present invention, the second layer is macroscopically expanded to provide a three-dimensional pattern in its surface, thereby increasing the amount of stand-off between the wearer's skin and the liquid impermeable first layer of the composite backsheet. The tiny apertures in the second layer substantially prevent occlusion of the wearer's skin by providing circulation of air between the first liquid impervious layer of the backsheet and the wearer's skin. This effect is enhanced even further when the first layer is macroscopically expanded to enhance the amount of stand-off between the wearer's skin and the liquid impervious first layer. The reduced contact area and the enhanced air circulation between the backsheet and the wearer's skin reduce the tendency toward perspiration and sticking of the backsheet to the wearer's skin.

Title: Robotic gripper
Inventor: HILL CHRISTOPHER PETER RALPH
IPC: B25J15/04
Filed: 1986-06-12
Abstract: A robot hand with a releasable gripper 18, in which the gripper is provided with a locating arm 88 which extends substantially perpendicular to a back face 90. The arm fits into a hole 44 in a gripper housing 22 which is provided with a gripper retaining means comprising an actuator pin 24 and a retaining pin 26 which are linked to operate together. To engage the gripper the retaining pin is removed from the hole by depressing the actuator pin such that the location arm may be inserted into the hole. Releasing the actuator pin allows the retaining pin to locate in a hole 92 provided in the location arm such that the backface of the gripper is loaded against an end plate 48 of the retaining means and held relative thereto. Releasing the gripper is achieved by reversing the above process. When not in use the gripper is mounted by pegs 72, 74 on a base 70. The actuator pin is depressed by engagement with a projecting slide 78 and the gripper engaged by moving the housing along the slide until the arm 88 is fully engaged in the hole 44. When the housing and gripper are together moved off the slide and base, spring 38 acting on pin 24 causes pin 26 to enter hole 92. <IMAGE>
