Abstract: A heat-adhesive paper sheet suitable for use as fusuma paper and shoji paper in a Japanese style house, wallpaper, ceiling paper, liner for paintings and calligraphic works, and liner for plywood, and which is adhered to the object with heat by ironing.  The heat-adhesive paper sheet is composed of a paper sheet material having a projection-depression pattern formed on the surface thereof by creping or embossing or the like and a layer of a thermoplastic thermal shrinking pressure-sensitive adhesive provided on one surface of the paper sheet material.  Even though the surface of the object to which the paper sheet is stuck is somewhat rough and uneven, the heat-sensitive adhesive layer may easily be fused so that the paper sheet may be well applied to the object under hight pressure without forming wrinkles on the applied sheet.   Steam ironing, which has heretofore been unacceptable, is applicable to this paper sheet for sticking it to an object.

Title: Header transport system
Inventor: FOX THOMAS RUSSELL
IPC: A01D47/00
Filed: 1992-07-14
Granted: 2002-04-09
Abstract: A header for a combine harvester includes gauge wheels which can be converted from a normal gauge position to a transport position in which the header is wholly supported by the gauge wheels and towed longitudinally of its length. One of the gauge wheels is a single wheel which moves inwardly toward the centre of gravity in the transport position. The other of the wheels is a walking beam system in the working position and forms a transverse axle in the transport position.      Each of the gauge wheels is mounted upon a bracket which can pivot about a horizontal axis from a raised spring biased gauge position to a vertically depending position allowing rotation of the wheel about a vertical axis on the bracket. The header therefore can be transported without the necessity for a separate trailer system.

Granted: 1996-02-13
Abstract: A convection air inlet and suds control device is provided for a dishwasher.  The dishwasher has a washing chamber with a bottom wall, and a chimney extending through the bottom wall with opposite upper and lower ends positioned on opposite sides of the bottom wall.  A chimney cap is spaced in covering relation over the upper end of the chimney.  A container having an inner cup and an outer cup is mounted adjacent the bottom wall such that the inner cup surrounds the lower extension of the chimeny. The outer cup includes an opening such that air may flow by convection into the outer cup, into the inner cup and upwardly through the chimney into the washing chamber so as to dry the articles in the dishwasher.  In oversudsing conditions, the suds flow downwardly through the chimney for collection in the inner cup.          Excess suds filling the inner cup will spill over into the outer cup.  The inner cup and lower extension of the chimney cooperate to function as a valve.  When liquid deriving from condensing suds in the inner cup rises to a level above the lower end of the chimney, downward flow of suds into the inner cup and upward flow of air through the chimney is prevented.  As the liquid evaporates to a level below the lower end of the chimney, the flow of air and suds returns to normal.

Patent CA-2118999-C (CA)
Inventor: REICHARDT KLAUS H
IPC: E03C1/29
Filed: 1994-03-14
Granted: 1997-12-16
Abstract: Water conservation is accomplished by a waterless urinal odor trap (10) containing a barrier (14) of oily liquid that is lighter than urine and thus allows urine to immediately permeate downwardly through the barrier (14) and ultimately discharge to an external wastewater disposal system, without requiring flushing, while acting continuously as an odor seal and thus eliminating the need for a conventional S- or P- trap. Odor trap (10) is readily assembled from two molded plastic parts (10A, 12) that snap together in a detent action to form an integral coaxial dual-chamber bell trap unit; this fits readily into a cylindrical cavity provided in a urinal system. The oily liquid is specially formulated to have low specific gravity, below 0.9, for operational efficiency and is made biodegradable for environmental protection of the wastewater system with regard to small traces that may escape. The only maintenance required is occasional replenishment of the oily liquid. Maintenance can be further minimized by the use of an auxiliary oil reservoir (20, 20A) serving one or more urinals. Subject odor trap meets safety and sanitation code requirements for public, business and residential facilities, provides important water conservation, operates at much lower cost than even the most economical of conventional flushing urinals, and is well suited both to new installations and retrofitting of existing facilities.

Granted: 2004-10-19
Abstract: In a data processing system which employs a cache memory feature, a method and exemplary special purpose apparatus for practicing the method are disclosed to lower the cache miss ratio for called operands. Recent cache misses are stored in a first in, first out miss stack, and the stored addresses are searched for displacement patterns thereamong. Any detected pattern is then employed to predict a succeeding cache miss by prefetching from main memory the signal identified by the predictive address. The apparatus for performing this task is preferably hard wired for speed purposes and includes subtraction circuits for evaluating variously displaced addresses in the miss stack and comparator circuits for determining if the outputs from at least two subtraction circuits are the same indicating a pattern yielding information which can be combined with an address in the stack to develop a predictive address. The efficiency of the method and apparatus is improved by providing pattern detection logic circuitry for searching for a plurality of patterns simultaneously and priority logic circuitry which establishes precedence in the event that more than one pattern is sensed with a given set of recent cache misses.

Abstract: Thermodynamically stable ceramic composites are provided for use in high temperature oxidizing environments. A phosphate selected from monazites and xenotimes functions as a weak bond interphase material between the constituents of the composites.  Monazite comprises a family of minerals having the form MPO4, where M is selected from the larger trivalent rare earth elements of the lanthanide series (La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, and Tb) and coupled substituted divalents and tetravalents such as Ca or Sr with Zr or Th.  Xenotimes are phosphates similar to monazite where M is selected from Sc, Y, and the smaller trivalent rare earth elements of the lanthanide series (Dy, Ho, Er, Tm, Yb, and Lu). High temperature ceramic composites that include monazite or xenotime and exhibit damage tolerant behavior or non-catastrophic fracture may be fabricated in a variety of material systems and reinforcement morphologies, including multilayered laminar composites; fiber, whisker, and particulate reinforced composites; and hybrid laminar composites. Alumina fibers may be used in single crystal or polycrystalline form as a reinforcement material. In preferred embodiments, the ceramic matrix comprises a material similar to the reinforcement to improve compatibility of the composite materials. The interphase material allows debonding and "frictional"  sliding between the constituents of the composite and inhibits crack growth across the interface.
