Title: Hard setting refractory composition
Inventor: RECHTER HAROLD L
IPC: C04B35/66
Filed: 1988-05-31
Granted: 1992-03-31
Abstract: ABSTRACT OF THE DISCLOSURE      Novel compositions are disclosed for the manufacture of gunning mixes and strong castable products for use as monolithic refractory and construction materials which may contain no lime bearing cements.  Bonding is based on the setting reaction of fumed silica with an alkali metal silicate preferably a particulate sodium or potassium silicate that slowly dissolves in water such as an anhydrous sodium silicate of Si02:Na20 molar ratio of 1:1 to 4:1; or an anhydrated potassium silicate having an Si02:K20 molar ratio of 3:1, or a hydrated sodium silicate having an Si02:Na20 molar ratio of 3:1.  Setting and mechanical characteristics allow this class of castable and gun mixes to be placed more rapidly into service since the time required for curing is much less.  Although initial set strengths are not as high as those of conventional castables, very high strengths can be made to occur shortly after setting by heating.  The addition of sodium hexametaphosphate was found to be highly beneficial to working and handling characteristics.

Granted: 1993-07-13
Abstract: ABSTRACT OF THE DISCLOSURE           Described is a membrane apparatus having particular application in hydrocarbon processes, such as separating ketone dewaxing solvent from a hydrocar-bon process stream.  The apparatus contains a  pressure resistant compartment containing flattened tubular mem-branes in a parallel stack arrangement separated by retentate spacers.  Internally each tube contains per-meate spacers  for  solvent outflow which permeate spacers extend the full length of the tubular membrane. The end of the tubes are not separated by retentate spacers and are clamped together such that solvent exits via the permeate spacers, while the clamping assembly design prevents the cocurrent exit of solution from the high pressure compartment at the solvent inlet location.

Abstract: A b s t r a c t The invention relates to a device in a chair, especi-ally an adjustable chair (1aa) having an articulation means (7) between a seat member (3) a back rest member (8a), so as to allow an alteration of the angular position therebetween, the alteration taking place by pivoting said back rest member (8a) around a pivoting point (8) whilst said seat member (3) is displaced along a predetermined sliding path. The invention is characterized in that the device comprises one or more curved sliding means (1), the radius of curvature (R) of said sliding means (1) or the center (4) thereof being arranged in accordance with given functional properties of said chair (1aa), it being observed that a smaller radius of curvature (R) or a corresponding sharper curve of the sliding means (1) involves a larger varyation from a minimum value to maximum value of the tangential angle (.alpha.),i.e. the angle between a horizontal plane (H) and a tangent to the curved slid-ing means (1), and it also being observed that a dis-placement of the center (4) of said sliding means (1) involves an overall change of the tangential angle (.alpha.) of the sliding means (1) in all positions thereof, which in turn means that for example an increase of the tangential angle (.alpha.) of the sliding means (1) may compensate for the increased weight from a person on the back rest member (8a) as the latter is taking a more reclined position, for thereby providing a chair which is in balance in all positions and rendering smaller friction than compared with prior art models.

Abstract: ABSTRACT   LIQUID LEVEL CONTROL SYSTEM    In the field of sewage collection and disposal liquid is commonly transported along a pipe from one place to another by vacuum applied at the pipe's delivery end causing ambient pressure in the tank into which the other and projects to force the liquid into and along the pipe.  The outlet from the tank is connected to a vacuum source via a primary, or interface, valve with a control system opening the valve when the tank fills up.  With sealed tanks it may be that, when the interface valve to the outlet is suddenly closed at the end of a withdrawal-of-liquid cycle, the rush of liquid and air still entering the tank may result in a sudden increase in the pressure within the tank which mimics the pressure usually experienced by the level sensing apparatus only when the liquid level in the tank reaches the "switch-on" value, with the result that the apparatus triggers the re-opening of the interface valve despite the fact that the valve has only just closed.  For this problem the invention proposes a solution which involves a valve control system that includes pressure responsive means comprising: a first chamber containing a first diaphragm having a port for applying pressure; bleed means enabling air to pass this diaphragm; and passageway means enabling air then to pass into a further chamber also containing a diaphragm operatively linked to the valve operating apparatus; so that, when a predetermined and substantially constant pressure is applied at the port, air bleeds past the first diaphragm into the further chamber to move the diaphragm therein to activate the valve control system, but when a surge of pressure is applied at the port the first diaphragm moves to block the passageway into the further chamber, thus preventing pressure being applied to the latter's diaphragm to activate the valve control system.    Some of the previous transport systems also experience a problem when the vacuum drops, for then the pipe can fill with liquid, the available energy is used up in friction losses, and liquid transport stops - a phenomenon known as "waterlogging", or "bog down".  Its chances of occurring can be reduced by ensuring that the interface valve shuts if the vacuum drops significantly, and the invention proposes that this be achieved by incorporating into the control system a secondary valve, itself operated by the same vacuum applied to the tank, so aranged that if the actuating vacuum drops significantly then the secondary valve operates to cause closure of the interface valve and prevent further liquid being drawn into the collecting pipe.  The invention suggests a secondary valve of a kind, known per se, in which a "pinching" pressure across the valve's flexible body flexes one or more sealing member inside the body to close the valve, whilst the application of a force perpendicular to the body's surface flexes the or each sealing member to open the valve.
