IPC: C01B21/04
Filed: 1984-03-16
Abstract: The sieve beds (11,12,13) of a molecular sieve type gas separation system (10) are cyclically subjected to a charge/adsorption on-stream phase followed by a purge// desorption regeneration phase and each bed is arranged to be open to ambient atmospheric pressure or a pressure related thereto during the regeneration phase. A fixed logic sequencer unit (35) provides two different overall cycle times and fixes the relative durations of each phase within the overall cycle times. A switching device (40), which preferably includes a flueric partial pressure sensor (Figure 2), responds to the pertaining concentration of a constituent gas in the product gas delivered by the system and switches between the two overall cycle times so as to maintain the concentration of the constituent gas in the product gas within predetermined limits.

Title: Ice making machine
Inventor: GOLDSTEIN VLAD
IPC: F28F19/00
Filed: 1984-08-31
Abstract: A heat pump system has a refrigerant circulation system that is cooled by passing through a thermal storage heat exchanger. The heat exchanger is supplied by ice from an ice maker and can store heat energy by accumulation of ice in the heat exchanger. The ice is generated by cooling a secondary refrigerant, typically brine, at the wall of a ice making machine and scouring the wall prior to crystallisation of the brine mixture to disperse the super cooled liquid adjacent the wall into the body of the secondary refrigerant. Crystallisation is then promoted in the body of the liquid. The ice generator in a preferred form comprises a series of flat plates having primary refrigerant passing between the flat plates and secondary refrigerant passing over the surface of the flat plates. A series of scrapers rotate about an axis normal to the plane of the plates to disperse super cooled secondary refrigerants throughout the body of the secondary refrigerant in the ice generator.

Title: An allergen absorbent and blocking gel
Inventor: POWELL THOMAS
IPC: A61K9/06
Filed: 1986-10-07
Abstract: An allergen absorbent and blocking gel for topical application to the skin comprises an organophilic clay of the smectite type and a quaternary ammonium compound, having aryl or alkyl groups in the range of from 10 to 22 carbon atoms and a vehicle comprising long-chain hydrocarbon or volatile silicone. The material can be made in the form of a stick, a salve or an aerosol spray. It is essential that the organophilic clay gel be highly activated. This is accomplished by high-shear mixing and/or by the use of a low molecular weight polar organic dispersant, such as propylene carbonate. This can also be accomplished using self-activating and self-dispersing clays which do not require high shear or polar activators. Application of the resulting highly-activated gel to the skin results in a blocking effect by means of the clay platelets and an absorption and retention of the urushiol oil allergen in the active tallow tails of the alkyl groups of the quaternary ammonium compound which has been ion exchanged with the clay.

Abstract: A valve, 100, has a valve body, 101, with a recess 115 engaged by a movable threaded plug 116. A valve control member, 117 in the form of a ball is positioned on the projecting end 118 of the plug 116 so that its upper surface projects into the valve chamber 113 by a pre-determined amount. In its use with a vehicle fuel system, the valve 100 would have its outlet connector 103 connected to the vehicle engine and its inlet 114 connected to the fuel tank. In filling the fuel tank the ball 117 is unable to prevent the flow of the fuel, such as compressed natural gas. In the event of a rupture in a fuel line, excess flow of fuel from the fuel tank through the inlet 114 will create a fluid flow turbulence within the chamber 113, which turbulence is enhanced by the presence of a projection 152 extending into the chamber 113. The degree of exposure of the ball 117 within the chamber 113 is sufficient at that pre-determined rate of excess fluid flow for the turbulence to lift the ball 117 and position it against the ball seat 107 to prevent or limit further fuel flow. Automatic re-setting of the valve 100 can be achieved if the ball seat 107 permits some fuel flow to continue. 
     Other embodiments of the invention provide for the re-setting of the valve by manual re-setting or by provision of a specific by-pass path.
