Granted: 1985-11-14
Abstract: An insulating pipe part of thermoplastic material comprises two opposite sections and one third section disposed at an angle with respect to the former sections, the wall portion of said sections being provided with a continuous wall cutting slit. The pipe part may comprise thicker parts of a polyurethan foam. For forming an insulated branch pipe joint, said insulating pipe part is pushed over a branch pipe and subsequently plastic sleeves with beveled front ends are heatshrunk on to said sections, thereby closing said slit in a moisture tight manner. In order to obtain a reliable moisture tight closing, the sleeves are provided with beveled front ends so that the lower sleeve ends overlap each other.

Date May 11, 1983.A size press, which comprises three coating rolls (11, 12, 13). These rolls (11, 12, 13) form two press nips (N1, N2) as pairs with each other, the paper web (W) to be treated being passed through the said press nips. Both sides of the web (W) are treated in the said nips (N1, N2). Out of the said coating rolls, regarding the position of altitude, the uppermost roll (12) has been arranged as the center roll of the size press, in connection with which center roll the two coating nips (N1, N2) are formed so that the first coating nip (N1) is placed at a short angular distance ( alpha 1) underneath the horizontal plane (H-H) placed through the axis of the said center roll (12). The second coating nip (N2) is formed by the third coating roll (13), which is placed substantially in the vertical plane (V-V) placed through the center point of the center roll (12) or at a small angle ( alpha 2) after the said plane. As preceding the first nip (N1), size-feed devices (24, 25) have been provided at the center-roll (12) side of the run of the web (W), which size-feed devices (24, 25) feed a first size pool (L1) or layer into the substantially vertical pit between the center roll (12) and the web (W). Preceding the second nip (N2), a second set of size-feed devices (26, 27) has been provided in the substantially horizontal pit formed by the center roll (12) and by the third coating roll (13), the said second size-feed devices (26, 27) forming the second size pool (L2) or layer at the opposite side of the web (W), as compared with the said first size pool (L1) or layer. The said devices are jointly operative so that, while the sizing is performed, the web (W) is supported by a roll face.

Title: Mixer
Inventor: KATZER JOHANN

Filed: 1983-07-19
Granted: 1987-10-29
Abstract: A device for adding a solid additive to a liquid has a liquid inlet, a liquid outlet and a receiving container for the solid additive in the form of a tablet or bar. The tablet or bar is hollow, being shaped like a cylindrical ring. The liquid is moved axially past the inner surface and outer surface of the cylindrical ring, and during wearing away of additive material, there is a reduction in the size of the outer surface and a corresponding increase in the size of the inner surface. Therefore, the overall surface area remains constant, which leads to constant admixing. Preferably, an inner tube spaced from the inner surfaces of the additive discharges liquid for flow across the inner and outer surfaces in the same direction.

Granted: 1989-12-28
Abstract: A reduced wreath condensation boiler. A feed duct for fresh oxygen-carrying air taken from the atmosphere and an exhaust duct for exhausting diluted combustion products to the atmosphere downstream from the extractor fan are essentially parallel, but not coaxial, minimizing heat exchange. A first heat exchanger is disposed above the heating body for providing heat exchange between the fresh air from the feed duct and the combustion products from the heating body prior to dilution. Deflectors channel a portion of the air from said first heat exchanger to sweep the free space situated between the heating body and its airtight enclosure, while the remainder of the air from the first heat exchanger is directed towards the burner. At least one calibrated orifice injects the air which has swept over the heating body into the exhaust duct for the combustion products upstream from the extractor fan. This boiler reduces the wreath of water vapor where the flue gases are exhausted to the atmosphere.

Abstract: The novel container can be used for hydroponics or plants in earth. In the case of one of its embodiments, a container shell (12), reinforced by a bead (42) and terminated at the bottom by a base (32), is surrounded by at least one sheet-metal strip (52,52'), which runs around at a distance from it and may exhibit a pattern, for example of holes. Depending on the season, cut flowers, sprigs of fir or the like can be inserted between the sheet-metal strip and the container shell, which, just as the breaking up of the form by the sheet-metal strip, additionally offsets the plain effect of a simple container and offers variation. A saucer underneath the container can supply the cut flowers with water, but of course also receive earth for permanent planting. Instead of this, the intermediate space between the container shell and the sheet-metal strip can also be provided for receiving a fluorescent tube or string of filament lamps, which illuminates from below the protruding parts of the plants rooted in the container, or be supplemented by a fluorescent tube within the rim of the container shell. <IMAGE>

Date Mar. 12, 1987.The present invention relates to a tracheostomy cannula with a small balloon or cuff (2) positioned posteriorly (or cranially) to the tube (1) which is consequently shorter. This tube (1) has a collar (5) that encircles the tube on its proximal portion and prevents air leakage through the stoma. The "cuff" (2) also may communicate with the environmental air by means of conduits (6) that may be flexible. Since the component structures of a cannula so formed progress only a small distance caudally into the trachea, some complications, if not completely avoided, are better guarded against. Thus, there is when using the present invention less stimulus to a coughing reflex. Moreover, its cleaning and that of the trachea are simpler, and a tracheo-innominate fistula will rarely occur.
