Granted: 1991-06-30
Abstract: @ The present invention pertains, in a particularly preferred embodiment, to an apertured, macroscopically expanded, resilient three-dimensional polymeric web which is believed to have particular utility as a breatheable barrier for a disposable bandage such as a diaper. The web preferably comprises a deeply drawn three-dimensional structure containing a multiplicity of debossments of macroscopic (i.e., visibly perceivable by the normal human eye at a perpendicular distance of about one foot) cross-section, each of said debossments originating as an aperture in a first surface of the web and having a continuously interconnected side wall extending in the direction of a second, remotely located parallel surface of the web. The side wall of each debossment terminates to form an end wall in the second surface of the web. The end wall includes a multiplicity of apertures, each of said apertures being sized and shaped to independently support an aqueous fluid meniscus. The smaller apertures in each end wall are so spaced relative to all adjacent apertures in the end wall that the aqueous fluid menisci supported in the apertures do not contact one another or the side wall. In a disposable absorbent bandage context, the second surface of the web containing the end walls with small apertures therein is placed in contact with the absorbent core portion of the bandage and the surface of the web in which the debossments originate is oriented so as to contact the wearer's outer garments in use.

Title: Improvements relating to the feed of lead to lead oxide mills
Inventor: STAMP THOMAS BLACKLEDGE
IPC: C01G21/02
Filed: 1962-01-05
Abstract: 1,017,203. Drum mills. CHLORIDE ELECTRICAL STORAGE CO. Ltd. Dec. 31, 1962 [Jan. 5, 1962], No. 486/62. Heading B2A. [Also in Division G3] The amount of charge in the rotary drum of a lead oxide mill is maintained at the maximum allowable level by controlling the feed of fresh material to the mill in dependence upon the current taken by an electric motor driving the drum, which current is related to the load on the motor and hence to the amount of charge. As shown, the mill drum 1 is supported on a hollow shaft having portions 2, 3 and is driven by an electric motor 5 through gearing 6. The drum is charged with lead pieces from a vibratory feeder 9 by way of a conveyer 8 and the shaft portion 3. The feeder 9 is controlled by the amplified output from a photo-cell associated with an ammeter 10 which is in the motor circuit and the pointer of which carries a flag which interrupts a light beam from a light source to the photo-cell to a degree determined by the position of the pointer, Fig. 2 (not shown). The arrangement is such that the charge in the drum builds up until the flag on the ammeter pointer obturates the photo-cell, whereupon the drive to the vibratory feeder 9 is stopped so that no further material is supplied to the conveyer 8 until the amount of charge in the drum again drops. In an alternative arrangement, the vibratory feeder 9 is driven continuously but is controlled so as to provide either a high or low rate of feed. Specification 1,017,202 is referred to.
