Abstract: LIQUID REFRIGERATION SYSTEM FOR AN ENCLOSURE TEMPERATURE CONTROLLED OUTDOOR COOLING OR PRE-CONDITIONING An economical energy-saving air-conditioning system for conditioning air in an enclosure requiring year-around environmental control. An outdoor heat exchangeris operative in a recirculating liquid closed-loop cooling system which utilizes cooler outdoor temperatures without affecting other environmental aspects of the enclosure. A temperature controlling arrangement provides continuous free outside cooling when the outside temperature is in the order of 35.degree. to 40.degree. F. or less; and provides free pre-conditioned cooling of the air when the outside temperature is in the range of about 35.degree. to 65.degree. F. The closed-loop comprises conventional components for summer temperature cooling; and, in less-than summer temperatures, the present invention utilizes the outside heat exchanger to provide coolliquid to a free cool coil positioned in the air stream advance of an evaporator coil. Reheat for dehumidification is provided in an improved embodiment - again the reheat is taken from the waste heat of the refrigeration system.

Abstract: ABSTRACT OF THE DISCLOSURE:                In a process for the manufacture of sodium dithionite by reacting sulfur dioxide with sodium formate and aqueous sodium hydroxide solution in the presence of methanol, an aqueous methanolic solution of sodium formate is first produced by reacting carbon monoxide with sodium hydroxide solution in an aqueous medium, containing from 1 to 50% by weight of methanol, based on the amount of water, at from 80 to 120°C under a pressure of from 10 to 40 bars.  The resulting aqueous methanolic solution can be reacted directly, in the convention-al manner, with sulfur dioxide and aqueous sodium hydroxide solution to give sodium dithionite.  The process has the advantage that in the first step the reaction gives, within a short period and at a relatively low temperature, aqueous methanolic solutions of sodium formate, which in the second step can be directly converted to sodium dithionite.

Abstract: ABSTRACT OF THE DISCLOSURE        An improved check valve is disclosed for use in a system for sequentially delivering primary and secondary solutions through a common conduit.  The check valve comprises a hollow housing with an inlet and an outlet connected to an enlarged intermediate portion.  Sealed at its periphery in the enlarged portion is a flexible diaphragm characterized by having foraminous means in at least its outer portion and imperforate means in its central portion.  The imperforate means is spaced from a valve seat surrounding the passage at the inner end of the inlet so that, when the primary solution flows from the inlet to the outlet, it will pass freely around the imperforate means and through the foraminous means.  When an increase in pressure, even though slight, is exerted against the diaphragm caused by flow of the secondary solution in the direction of the outlet to the inlet, the diaphragm moves towards the inlet causing the imperforate means to seal against the valve seat and stop the flow of the primary solution.

Title: Energy efficient method of producing zinc electrodes
Inventor: BILHORN JOHN M
IPC: H01M4/02
Filed: 1978-12-06
Granted: 1981-12-22
Abstract: ABSTRACT OF THE DISCLOSURE     The improved method of the present invention comprises mixing zinc particles comprising zinc metal and/or zinc oxide with a concentration of bonding agent sufficient to bond the particles together when subject to mechanical roller pressure so as to form a continuous film but insufficient to totally encapsulate the particles, treating the resultant mixture to form a freely flowable doctorable powder of mesh size below about 40 mesh, doctoring the powder to a desired thickness on a conveyor, rolling the doctored powder in a nip between pressure rollers to form a continuous film, combining the film with a current collector and then dividing the resultant film into zinc electrodes of predetermined size.   The bonding agent preferably comprises latex, that is, a dispersion of natural and/or synthetic rubber in water, in a concentration of about 0.5 to about 5 wt. percent of the mixture with the zinc particles.  The zinc-bonding agent mixture may include a minor proportion of a gas control agent such as mercuric oxide in powder form.  The current collector preferably includes a flexible metallic mesh or perforated sheet of copper or the like.  In carrying out the method, the current collector may be passed into the pressure nip along with the doctored powder during formation of the film.          If desired, the current collector can be placed on the layer of doctored powder and then a second layer of the powder can be disposed on the free side of the current collector, and then doctored before this composite passes through the pressure nip to form the desired product.  In another embodiment, two of the rolled films can be independently formed and then the current collector can be placed therebetween and the resultant composite can then be passed through a pressure nip to unify the composite.          The electrode is thus formed in a relatively simple, rapid, flexible and efficient manner.

Abstract: Priese Case 217 FIRE RESISTANT SEAT FOR BUTTERFLY      AND BALL VALVES           Abstract of the Disclosure The invention contemplates a flow control valve that provides emergency sealing action upon inadvertent, thermally induced failure of the primary seal.  The body of the valve includes an annular shoulder that is disposed adjacent an annular seat; and an annular collar of substan-tially incombustible corrosion resistant, nongalling material is specifically mounted on the shoulder, the collar includ-ing a first portion hermetically connected to the shoulder and a second, lip like portion free to move with respect to the shoulder and normally spaced from the selectively positionable valve element.  This collar and more spec-ifically the lip portion thereof is provided with pre-stressed regions normally situating the lip portion proxi-mate the body shoulder and in position wherein said lip portion will not interface with the movable valve element.          Upon thermal relief of the stresses stored in such regions, the collar reacts to dispose the second, or lip portion into sealing engagement with the valve element when in the flow aperture closing position. This stress relief is perm-anent, such that upon subsequent cooling of the valve, the collar lip portion will remain in sealing engagement with the valve element, thereby preventing leakage, even though the primary seal may have been destroyed by the thermal event.

Abstract: ABSTRACT      Adjoining edges of sheets of pre-coated metal or other rigid material may be interlocked against movement transversely apart by forming the edge of a first sheet with a lock member constituted by a transversely offset reverse flange having at its extremity an outwardly directed first hook member and forming the adjoining edge of the second sheet with a transversely offset projecting flange whose extremity forms a second hook member directed inwardly.  The sheets may be locked together by superposing the second hook member over the first hook member with the projecting flange behind the reverse flange and with orthogonal flanges spaced slightly apart and relatively rotating the sheets to a fully interlocked position defined by abutment between the orthogonal flanges.  The above arrangement can advantageously be used in the vertical rear corner joints of a pre-coated steel cabinet where it is helpful to be able to assemble the cabinet from its major components without the need for pop-riveting or the like.
