Granted: 1993-06-15
Abstract: P.C. 7474 ABSTRACT OF THE INVENTION      Disclosed is an apparatus for controlling the discharge of materials through a body passage.  The invention comprises a fluid actuated artificial sphincter mechanism that surrounds the body passage. The artificial sphincter includes an inflatable cuff (16) surrounded by a hollow resilient C-shaped reservoir ring (18).  The cuff, ring and pump (20) are in fluid communication with each other.  The fluid communication between the duff and reservoir ring is controlled by a flow resistor means (49).  In operation, the pump draws fluid from the cuff and diverts the fluid into a reservoir ring.  By pumping the fluid from the cuff, the cuff deflates opening the body passage.  Pumping the fluid into the reservoir ring increases the pressure in the ring causing the ring to open.  As the ring opens the ring allows the cuff to move further away from the body passage opening the body passage further.  The fluid displaced in the ring is continuously diverted from the reservoir ring back to the cuff.  A flow resistor controls the flow rate of fluid back into the cuff.  The resistor allows the cuff to gradually re-inflate to again occlude flow through the body passage.

Abstract: The invention relates to a method for cleaning a valve sealing arrangement under dynamic stress, and an apparatus for carrying out said method, each sealing arrangement sealing two spaces from one another by means of two seals, separated from one another, in a serial arrangement, between or in which spaces there is arranged in a moveable manner a valve part whose jacket surface interacts with the seals and thereby prevents fluids overflowing from one space to the other, an annular space, enclosing the valve part, being provided between the seals, which annular space is bounded on the outside by a housing of the valve and which is connected via at least in each case one connection and one outlet opening to the environment of the valve. The invention ensures, inter alia, that even those critical regions of the slots for the seals which can be accessed only with difficulty are reliably subjected to the cleaning agent. In terms of the method, this is achieved, inter alia, in that the seal which comes into contact with the fluid to be sealed off is supplied with cleaning fluid from the spaces on both sides of the contact surfaces, up to its contact surfaces (provided temporarily at the sealing points) with the valve part on the one hand and the housing on the other hand. The apparatus for carrying out the method is characterised, inter alia, in that each seal (70, 71) is edged in each case on its side facing the space inside the valve housing part (1 or 2) to be sealed by a fluid-permeable boundary wall (41), and in that each of the seals has a limited mobility in the direction of movement of the valve part (4). <IMAGE>

Abstract: A method for producing expandable thermoplastic microspheres by polymerisation in a reaction vessel of an ethylenically unsaturated monomer or a mixture of monomers in an aqueous suspension in the presence of a condensed propellant. In the method, the monomer or monomer mixture is suspended in the aqueous medium in the presence of a powder stabiliser which consists of a salt or hydroxide of any of the metals Ca, Mg, Ba, Fe, Zn, Ni or Mn. The powder stabiliser is insoluble in the aqueous medium at the pH the aqueous medium has at the polymerisation. The aqueous medium may also contain a co-stabiliser. The method further comprises the step of washing off the powder stabiliser from the microspheres after the polymerisation by lowering the pH of the aqueous medium by the addition of acid. Alternatively, amphoteric hydroxides can also be dissolved by a pH increase. The invention also relates to microspheres produced according to the method of the invention, and to the use thereof.
