Abstract: Abstract of the Disclosure A control valve assembly 10 for use in a system for heating water is disclosed.  The system includes a source of steam 12, a steam condensate trap, a source of cold water, a heat exchanger 14 to transfer heat from the steam to the cold water, and an outlet where heated water is used.  The control valve 10 assembly includes a dual valve structure which splits the flow of incoming cold water, directing one portion of it to the heat exchanger 14 and bypassing the other portion of the incoming cold water around the heat exchanger.  The two portions of the incoming water rejoin in a blending chamber 16 which is connected with a water line to supply blended hot water to an outlet such as a shower or faucet.  A controller 36 within the control valve assembly 10 is responsive to the demand for blended hot water.  The controller regulates valves 18 and 22 which control the flow of water through the heat exchanger 14 and the flow of water bypassed around the heat exchanger to maintain the temperature of the water leaving the blending chamber 16 constant despite variations in the flow rate of blended hot water through the outlet 20.

Abstract: PROCESS AND APPARATUS FOR TRANSFERRING       AND STERILIZING A SOLUTION                 ABSTRACT OF THE DISCLOSURE       A process and apparatus for the transfer of a parenteral solution into an extensible plastic bag and the sterilization of that solution during such transfer.   The  apparatus  include a hydrophilic,  bacterial  organism retentive,  sterilizing filter, such a bag, and tubing connecting same, which have been combined and sterilized as a unit, which unit is labeled for sale as being sterile.  A container holding the solution to be transferred and tubing associated therewith are provided  for delivery of the solution to the sterile unit.  A vacuum chamber is also provided by which the solution may be rapidly drawn through the filter, as it is sterilized, and into the bag upon the creation of a pressure differential between the inside and outside of the bag in the vacuum  chamber.   A  transparent  portion  of  the sterile  unit provides a means by which the sterility of the transfer process can be determined.  The process includes delivering the solution to the sterile unit, transferring the solution through the filter for sterilization  and into  the bag by creating the pressure differential, terminating solution transfer and directing a gas through  the  unit,  observing  the  transparent portion  for the presence of gas bubbles, which would indicate a loss of filter integrity,  and consequently sterility of the unit,  and herme-tically sealing off the bag, if no such bubbles are present.

Abstract: ON-SITE WASTEWATER TREATMENT SYSTEM      Abstract An on-site wastewater treatment system is disclosed suitable for treatment of domestic or other sewage.  Incoming wastewater is passed into a septic tank (1) with the effluent then passed into a basin (3) holding particles of a media (5) through which the effluent travels.  The media (5) removes a substantial amount of the suspended solids in the effluent and some of the BOD (biological oxygen demand material).  The filtrate is collected in a recirculating tank (7) and then pumped by pump 8 for dispersal, preferably by spraying through nozzles placed above the surface of the same media (5) for travel therethrough a second time.  The media (5) retains the effluent until the surface tension of the efflu-ent between the particles of the media (5) is overcome by gravity, at which time it is displaced from the media (S) and discharged.  During the retention time, aerobic action in the media (5) reduces the bacterial count of the effluent signi-ficantly.  The effluent from the septic tank (1) is preferab-ly alternately distributed between a first area (4a) of the media (5) and a separate second area (4b) of the media (5) in order to allow continuous regeneration of the media (5) by avoiding a continuously ponded condition and by the action of the aerated effluent.

Abstract: Abstract of the disclosure: In the manufacture of a building element of the type in which an internal core member of a material of an open air-permeable structure is to be covered on both side faces with cover boards and on the edge faces with edge strips by gluing with a moisture-curing adhesive, contact pressure is estab-lished by applying suction directly through an opening in one of the edge strips to produce an underpressure in the core member. Thereby, and by applying the amount of moisture necessary to cure the adhesive to the cover boards prior to application of the adhesive, a consider-able reduction of the processing time and, thereby, a simplification and cost reduction is obtained. Relative to usual mechanical pressure application technology, adhesive bonds having improved strength characteristics are obtained together with effective removal of poison-ous fumes arising during the curing.

Abstract: ABSTRACT OF THE DISCLOSURE           The apparatus molds during each cycle homogeneous plastic material and foam plastic material.  It includes a barrel member, a main passageway therein in which is located the screw member.  A pair of injecting means for filling molds are provided, one having a homogeneous plastic injection chamber and the other having a foam plastic injection chamber.  The first injection means is connected to the screw and barrel member up-stream of the place where the inert fluid is introduced into the main passageway whereby homogeneous plastic material is dis-charged from the main passageway into the first injection means.          The apparatus includes means for introducing an inert fluid into the main passageway whereby the rotating screw member mixes the gas with the molten plastic as it moves towards the discharge port which is connected to the second injection means whereby foam plastic material is injected into the foam plastic injection chamber.  Each injection means has one or more nozzles connected to a mold located in a press.  The molds for both the homogeneous and foam plastics material may be located in different presses or in the same press so that upon each cycle of the screw and barrel assembly and after both injection means have injected the plastic materials into the respective molds, the press or presses close and form the homogeneous plastic parts and the foam plastic parts.  The several injection means or devices may be operated simultaneously or sequentially.  Thus, it is possible to mold and form homogeneous and foam plastic parts during the same cycle using only one screw member.
