An insert for a siamese-type internal combustion engine that separates a water jacket surrounding the cylinders into an upper portion and a lower portion. Below a predetermined engine speed coolant flows primarily in the upper water jacket portion so as to provide enhanced cooling at the upper portions of the cylinders. Above a predetermined engine speed coolant is introduced into the lower water jacket portion from the upper water jacket portion so as to provide improved cooling of the lower cylinder portions, without compromising cooling of the upper cylinder portions or the conjoined cylinder wall portions. The water jacket insert enhances coolant flow velocity at the siamesed or conjoined portions of the cylinder walls, and directs incoming initially coolant over the exhaust-side of the cylinders. Use of the insert reduces circumferential and axial intra-cylinder temperature deviations as well as inter-cylinder temperature deviations.

A method for alteration of the morphology of cellulose fibers, particularly softwood fibers, by (a) subjecting the fibers to a metal ion-activated peroxide treatment carried out at a pH of between about 1 and about 9, preferably between 3 and 7, and (b) subjecting the treated fibers to a refining treatment thereby converts SW fibers to HW-like fibers in many respects. The metal ion-activated peroxide treatment has been noted to act on pulp cellulose and hemi-cellulose, causing oxidation and oxidative degradation of cellulose fibers. The chemical treatment of the pulp, taken alone, is not sufficient to attain the desired modification of the morphology of the fibers, however, subsequent refining or like mechanical treatment of the chemically-treated fibers to achieve a given degree of refinement of the fibers requires dramatically less refining energy to achieve a desired end point of refinement and to impart other desirable properties to the pulp. A pulp of modified SW fibers and a mixture of HW fibers and modified HW fibers are disclosed.

A novel filler treatment comprising the preparation of swollen starch-latex compositions, prepared in the presence or absence of co-additives, and the addition of the said composition to a filler suspension, has been developed. Use of the treated filler during papermaking improves filler retention and produces filled papers where addition of the filler has only a minimal negative effect on strength properties. The swollen starch-latex compositions can be prepared in a batch or jet cooker, or by mixing with hot water under controlled conditions (i.e., temperature, pH, mixing, mixing time) in order to make the starch granules swell sufficiently to improve their properties as a filler additive but avoiding excess swelling leading to their rupture. The swollen starch-latex composition is then rapidly mixed with the filler slurry, preferably in a static mixer, and added to the papermaking furnish at a point prior to the headbox of the paper machine. The starch-latex composition can be used with wood-free or wood-containing furnishes. The treated filler is easily retained in the web during papermaking, improves drainage, and gives sheets having good formation. Sheets made with the treated fillers have higher bonding and tensile strengths than sheets produced using filler treated with either swollen starch alone or latex alone. Retention and drainage are further improved when conventional retention aid chemicals are added to the furnish containing the treated filler. The use of swollen starch-latex compositions could allow the papermaker to increase the filler content of the paper without sacrificing dry strength properties or increasing the amount, and hence the cost, of the retention aid added. The combination of swollen starch and latex could be used as furnish additives in the manufacture of both filled grades and grades that contain no filler such as sack papers and paperboard products.

A drain pan for capturing condensate from a cooling coil in an air conditioning system is configured to facilitate condensate drainage from the pan and to inhibit accumulation of condensate therein. The pan includes troughs for collecting condensate and for channeling the condensate to the front part of the pan where the drain openings are located. A back trough has a central hump to enhance the flow of condensate from the back trough in both directions into opposed side troughs. The side troughs are sloped from back to front to conduct the condensate into a front trough to facilitate drainage from the pan. The lowermost portion of the front trough region is defined by a relatively narrow, non-flat area to reduce the amount of condensate residue in the pan.

This invention is related to wound dressings, supports, protection and care in humans and animals. Commonly, adhesives and wraps are used for this purpose. However, the use of adhesive have multiple problems: they are difficult to use with elastic gloves since the adhesive tapes stick to the gloves, cause skin irritations and discomfort on removal, and do not adhere to the skin covered by hairs. Many times the hair must be shaved which is a process of its own. Wound inspections or the exchange of dressing multiplies their problems and prohibits this process. Furthermore, wound wrapping cannot be done by use of adhesive tapes in an effective and convenient manner. Then, of course, is the major issue of dressing a wound with one hand only, that occurs in certain circumstances. It is very important to have a system that allows a person to be able to dress a wound solely with one hand, since the other one may be wounded. These units are extremely helpful in this regard. Lastly, at times the wound dressing should be done as quickly as possible, and obviously speed makes a big difference in manmade or natural disasters. Also in many cases the wound site needs to be protected by means that will prevent objects from touching the skin or the wound site, in order to prevent ulceration, avoid discomfort or simply the mere protection of the wounds. In some other cases, the vascular problems of the wounds need to be addressed for better care. This would, in some cases, need means of squeezing the wound site, and in other cases allow a better drainage of the wounds. The methods and means introduced solves many of these problems. This application introduces new methods and means of dressings that makes the process of wound dressing faster, easier, and applicable with one hand only. It practically eliminates the use of adhesives and / or decreases their use significantly. In this model, a support unit made from a non-stretchable material, commonly in a rectangular or trapezoid shape, is used on the wound to hold the gauze pad or wound dressing in place. This unit uses at least one strap made of a particular stretchable material that allows the strap to attach to the support on a detachable, re-attachable basis to a band of the hook fastener on the surface. Importantly, this attachment can be done in any part of this strap. Also importantly, this support system uses one or two narrow bands made from the same material as the strap, which allows them to wrap around the limb from the opposite side of the strap to attach to the support on a detachable, re-attachable basis. Next, the main strap will attach to the support on detachable, re-attachable basis. In some models the support unit will function as the stabilizer of the system or to make the functions simpler. This main idea is then used to make multiple models for use in different areas. The application has also shown modified versions of these units that function to prevent ulcerations from starting in places such as the heels. In some other models the applicant shows units that guard the wound site and prevent objects from touching the skin or the wound site for avoiding discomfort or mere protection of the wounds. In patients who have vascular problems the models shown here allow the wound in the heels to be squeezed to prevent and reduce tissue swelling. In other cases, the applicant shows means that allow a limb to be elevated for a better drainage. All in all, the applicant tries to introduce units for improving human and animal quality of life.
