IPC: E03C1/04
Filed: 1993-07-12
Abstract: This invention relates to valve assemblies and particularly to valve assemblies adapted to prevent backflow which also incorporate an atmospheric vacuum breaker. The most basic arrangement involves a vacuum breaker device (16, 28) which comprises an integral non-return valve located upstream of a user operable valve control means (21) wherein the non-return valve of the vacuum breaker device is biased to close against the flow of fluid from the supply (Fig. 14). The second of these variations shows a vacuum breaker device comprising an integral non-return valve located upstream of the valve assembly outlet wherein the non-return valve is biased closed but which is limited in its movement to allow flow of fluid through the valve assembly by a user operable valve control means (Fig. 7). The third of these variations comprises the addition of a second non-return valve (17) upstream of the vacuum breaker device (Fig. 13). The fourth of these arrangements is conceptually identical to the third arrangement but offers an alternative construction (Fig. 12). The fifth of these arrangements shows a vacuum breaker device upstream of the valve assembly outlet and a second non-return valve further downstream wherein the second non-return valve is biased closed to allow flow through the valve assembly by a user operable valve control means (Fig. 16). Other arrangements for a ball valve (Fig. 22) and various bib-cocks (Figs. 23 - 34) are also described. <IMAGE>

Title: Compression release valve for a combustion piston engine
Inventor: EDLUND DAG
IPC: F02N19/00
Filed: 1996-06-05
Abstract: The valve housing 12 is threaded into the cylinder wall 16 and has a chamber 20 with an opening 24 to the combustion chamber 22 and outlet holes 26 connected to the atmosphere. The chamber 20 contains a movable valve element 28 with a conical surface which cooperates with opening 24. The housing 12 is made of a material, eg nickel steel Invar, with a low coefficient of thermal expansion while the valve element 28 is made from a material, eg magnesium, with a high coefficient. When the engine is cold, the element 28 is spaced from the opening 24 eg by 0.1 to 0.2 mm so that starting is easier whether manually or by motor. When the engine starts there is very rapid heating of the valve element 28 which expands axially and radially to seal the opening 24. In a modification (figs.3,4a,4b) the valve element 28' is in the form of a shim with a spigot 29' which cooperates with the opening 24. The expansion coefficient of the chamber may be higher than that of the valve element which terminates in a cone 30'' on the combustion chamber side of the opening 24 (fig.5). The valve may be located in the piston (fig.6). The valve is fully automatic for easier starting compared to the known semi-automatic valves which are opened manually but are closed automatically when the engine has started.

Title: Recovery of High-Boiling Point Solvents Using Adsorption
Inventor: AKAMATSU MIKIO
IPC: B01D53/81
Filed: 1996-12-20
Abstract: Apparatus for recovering high-boiling point solvent vapour from gas comprises a honeycomb-structured rotor 1 having an adsorbent supported thereon, a separator 6 for partitioning each end face of the rotor into an adsorption zone 5, a desorption zone 4, and optionally a purge zone 7. Fan F1 blows the gas A contaminated with solvent through a cooling means C1 and through the adsorption zone where the solvent is removed. Most of the clean gas effluent a is released to the atmosphere, except for a fraction that is heated by heater H, and passed through the desorption zone 4 to remove the previously adsorbed solvent. This hot solvent enriched gas S is fed to cooling means C2 to liquify and separate out the solvent L, producing a cooled lean gas V. Fan F2 causes the lean gas to be recombined with the contaminated gas A supply for recycling through the system. If a purge zone 7 is present, then the clean gas a is passed through this zone to cool the adsorbent, before it is heated and passed through the desorption zone. A method of recovering high-boiling point solvent using this apparatus is also disclosed.

Filed: 1997-02-03
Abstract: A scanner having a photosensitive scanning array includes a timing generator having (a) a first state wherein pixel clock signals with a predetermined frequency are produced and (b) a second state wherein a D.C. restore clock signal with a frequency that is "N" times slower than the predetermined frequency is produced. The timing generator controls the rate of sampling the scanning array to acquire image data by producing a series of analog image signals containing (a) a video component which is characteristic of a density pattern of a scanned image and (b) a D.C. offset component which is characteristic of the scanning array. The timing generator also controls the rate of sampling the scanning array to acquire an analog signal containing only the D.C. offset component. A D.C. restore calculates an output signal containing only the video component of the series of analog image signals containing the video component and the D.C. offset component. The timing generator is selectively switched to its first state during acquisition of the image data, and to its second state during acquisition of the analog signal containing only the D.C. offset component.
