Abstract: The process for the production of closed-cell, extra soft polyvinylchloride foam plastics having improved volume stability at elevated temperatures. The process includes heating a plastisol or plastigel comprised of a plasticizer and foaming agent containing polyvinyl chloride or vinyl chloride copolymerizate in a pressure mold at a pressure of up to 300 atm. to a temperature of 150 DEG  to 180 DEG  C. for 1 to 2 hours. The plastigel or plastisol is cooled, at an unchanged closing force of the press of said pressure mold, to a temperature of 20 DEG  to 70 DEG  C. The plastigel or plastisol is removed from the pressure mold, a crude foam plastic forming. The crude foam plastic is heated under a gas pressure of 2 to 10 atm. to a temperature of 140 DEG  to 170 DEG  C. The crude foam plastic is cooled at said pressure of 2 to 10 atm. to a temperature of 100 DEG to 130 DEG  C. The pressure is lowered to atmospheric pressure, the foam plastic simultaneous expanding. The resultant foam plastic will not shrink or expand more than 5 percent after storage for one week at 60 DEG  C.

Abstract: A thermal turbomachine such as an axial flow steam turbine of the center intake opposite flow type includes an intake duct surrounding the rotor and which is delimited by a portion of the internal surface of an inner housing surrounding the rotor and by the juxtaposed surfaces of two rotationally symmetrical shells. In order to permit the shells to expand substantially unhindered in relation to the inner housing as a result of imposed thermal stresses and still provide a gastight seal between an internal surface portion of the inner housing and the peripheral portions of the shells the latter are pressed into a slidable sealing engagement with the former rather than rigidly attached to each other. According to one embodiment, the slidable sealing engagement between the parts is established by means of a groove provided on one part into which the other part is fitted. In another embodiment, the peripheral portions of the shell are pre-stressed so as to press against and slidably engage the internal surface of the inner shell.

Abstract: Continuously operating inside flow filter for placement within a pressure tank, comprising one or several filter cartridges filled with a filtering mass and an alkalizing mass placed around a sludge cylinder fitted upon a bottom grating, and the pipe system associated with the equipment, with valve control. Both the water filtering and the flushing have been arranged to take place by operating one single three-way valve known in itself, in such manner that during filtration this valve and the drain valve in the bottom of the tank is closed and the water flows from the water mains through the three-way valve and a check valve and through a pipe into the lower part of the tank in among the mass, whereby the iron will be precipitated. During use of water the water flows under effect of pressure through the finely divided mass in the filter cartridge, the iron becoming thereby adherent to its surface layers, while for accomplishing the flushing the water pump is kept switched off and the water mains valve is kept closed and the drain valve opened, whereby as the three-way valve is opened and when the pump has started, the iron precipitated during the counter-flow flushing will flow through the top of the filter cartridge and into the sludge cylinder in the lower part of the pressure tank.

Abstract: A beverage brewer structure wherein a pour-in basin is provided with an overlying wall member for preventing liquid which may inadvertently pass downwardly through the top wall of the brewer housing from falling into the basin so as to avoid contamination of the water to be used in the brewing operation. The housing may include a top wall having an opening in which is mounted a warming station and the protective structure is arranged to prevent water or liquid from passing downwardly from the warming station opening into the basin. The wall member may be inclined toward an edge portion of the basin so as to cause the undesirable liquid to flow away from the basin. The wall member may be suitably heated as by heat transfer association with the water heating tank of the beverage brewer so as to cause evaporation of the undesirable liquid which may fall thereonto. The wall member may further serve as an antisplash device for preventing splashing of the poured-in-water outwardly through the portion of the basin underlying the wall member. A delivery conduit may be provided for delivering water to the basin from a pressurized water supply. The delivery conduit may extend through a suitable opening in the wall member which thus serves to retain the conduit end portion in proper relationship to the basin. The wall member may include securing portions arranged to secure the wall member to the basin and the basin to an upstanding support on a shelf portion of the housing. The shelf portion may be reinforced by brackets which may be secured to the upper end of a rear upstanding portion of the housing. The basin support, in turn, may be secured to the brackets. The basin and upstanding support therefor may have interlocking portions for accurately locating the basin in a preselected overlying relationship to the hot water tank.
