Abstract: NON-JAMMING BIN LID SYSTEM            Abstract of the Disclosure A balanced lid type system for industrial trash bins includes arrangements for partially opening the lid with little effort and for permitting the lid to swing wide open when it is inverted for dumping, as disclosed in U.S. Patents 3,994,415 and Re. 29,494. The operative mechanism in the present balanced lid bin system includes rollers which ride on the top edge of the sides of the bin to support the lid in a substantially balanced manner, and a pair of recesses or guideways in the rear sides of the lid which engage matching pins or rollers extending laterally from the bin to guide the lid as it rotates open in the upright or balanced partially opening mode of operation.          When the lid swings wide open, as it is inverted when raised by the forks of a lift garbage dump truck, the rollers remain at the end of the tracks in the lid and the lid swings fully open about this axis.  In the wide-open position, the tracks of the lid make a substantial angle with the vertical, so that vibration of the bin to assure complete emptying of it, will not jam or damage the tracks or mating roller assemblies.

Abstract: Abstract of the Invention A device which supports and cushions the human foot by means of fluid pressure is disclosed.  The device is non-elastic and self-supporting.  Two superimposed plies of a fluid impervious woven fabric material are sealed to each other around the periphery and, according to predetermined design, at selected areas within the periphery.  The result is a series of foot supporting pneumatic cushions inter-spersed and separated with void regions which do not touch the underside of the foot.  The fluid containing chambers which form the pneumatic cushions are in communication with each other through fluid passageways located around the periphery of the device.  The device permits fluid to flow from one internal chamber to another when compressed, but with a back pressure build up sufficient to prevent sudden surges of fluid from one chamber to another.  This provides additional pressure which resists and cushions the impact of the forces applied to the device.

Abstract: INVENTORS:   ALFRED BUBIK and SIEGFRIED REUTTER          INVENTION:   DOUBLE FILTER PAPERMAKING MACHINE     ABSTRACT OF THE DISCLOSURE     A double filter papermaking machine comprising two filters guided over a dewatering cylinder.  A first one of the filters contains a linear section or path  located in front of the cylinder.  A domed dewatering or slide shoe, shorter than such linear section, is arranged ahead of the cylinder.  The second filter is equipped with an adjustable guide roll, by means of which it is possible to regulate the contact location of the second filter at the first filter, and specifically, between a location disposed at the starting region of the shoe and a location arranged after the shoe at the dewatering cylinder.  A regulation device or regulator can be provided which contains a feeler for sensing the pos-ition of the water line at the dewatering cylinder.  As a function of signals transmitted by the feeler the regulator adjusts the guide roll in a manner such that with a displace-ment of the water line from a reference position opposite the direction of movement of the filters the contact location is adjusted in the direction of movement of the filters and vice versa.

Abstract: ABSTRACT OF THE DISCLOSURE            In footwear of most varieties including boots and shoes, there is described improved footwear wherein the upper or boot portion of the footwear, including a safety toe cap, is detachably connected to the lower or heel and sole portion of the footwear.  Known footwear is integrally formed such that damage to the safety toe cap necessitates replacement of the footwear if the safety features of the boot are to be maintained.          In this invention, releasable fasteners such as hooks are depl-oyed about the periphery of the sole.  These hooks engage a con-tinuous flexible wire which extends around the lower periphery of the upper portion of the footwear.  A toe cap is formed with similar hook fasteners along its lower periphery which also en-gage the flexible wire.  The toe cap hooks are spaced to fit be-tween the hooks deployed about the periphery of the sole when installed. Accordingly, the toe cap may be secured to the upper portion prior to attachment of the upper portion to the sole.          Inward pressure applied to the lower edge of the upper portion will release the upper portion and thereby facilitates repair or replacement of the toe cap.

Abstract: RASTER DISPLAY APPARATUS     ABSTRACT    A raster display apparatus capable of displaying graphic pictures includes a processor for loading character codes (pointers) in a character buffer. The pointers address a character/cell generator to derive the bit patterns necessary to refresh the display under control of refresh logic.  As the picture becomes increasingly complex, re-quiring more and more different character cells, the character/ cell generator fills.  Space is created by combining two or more adjacent cells into a single low-resolution-displayed cell:  an op. code associated with each character code (pointer) determines whether the cell is to be displayed at full or reduced resolution and causes the refresh logic to clock bit patterns associated with low resolution cells at a slower rate.  Optionally, the processor changes low reso-lution parts of the picture to high resolution when an operator interacts with the low resolution part using a light pen.
