Abstract: PCT No. PCT/SE80/00130 Sec. 371 Date Jan. 4, 1981 Sec. 102(e) Date Dec. 23, 1980 PCT Filed May 5, 1980 PCT Pub. No. WO80/02369 PCT Pub. Date Nov. 13, 1980.A device for temporarily or permanently closing body passages or cavities in humans and animals and including a member (2) of a material which swells at least 20% by absorbing body fluids and which is substantially inert to body fluids and surrounding tissues, the member (2) being dimensioned so as to be able to be introduced with clearance into the passage or cavity in its unswollen state but to take up the whole cross-section of the passage or cavity in the swollen state and then to be held by pressure against the surrounding walls of the passage or cavity. The device also comprises an element (7) with outer portions (8) which, in the unswollen state of the member, project out from its surface and which are made of a material with such suitable stiffness that the element with said outer portions (8) spreads out, in a yielding manner, towards the surrounding walls of the passage or cavity in such a manner that the element tends to lock the member in its inserted position by pressure against the wall, which ensures holding of the member before it has developed any direct pressure against the surrounding wall through its swelling.

Abstract: For mounting a protective sleeve of plastic over a joint between prefabricated heat insulated pipes, typically subterranean district heating pipes, an axially split plastic sleeve is inserted laterally over the joint so as to bridge the opposed ends of outer protective plastic tubes of the joined pipes. A plastic welding strip provided with a number of embedded parallel heating wires, is placed along and over the relevant annular joint with its opposed ends located spaced from each other adjacent the axial split of the sleeve. The ends of the strip are provided with terminals for parallel connection of the embedded wires, and the wires are electrically heated to weld together the welding strip and the two plastic tube ends. The axial split is then scaled by a similar welding strip.

Title: Continuous process for the separation of partially water soluble component from a slurry
Inventor: STEUDE HEINRICH E
IPC: B01D3/14
Filed: 1990-06-06
Granted: 1998-10-20
Abstract: A continuous multistage process for separating a partially water soluble organic component from a slurry containing an insoluble solid, a partially water soluble organic component and optionally water.  In this process, the slurry is continuously fed to a tower or column equipped with a suitable vapor/liquid contact device.  Energy is applied at a point below the vapor/liquid contact device.  Vapors containing the partially soluble organic component exit the tower or column overhead and the inorganic solid is recovered at the bottom of the tower or column.  This application of distillation technology to slurries is particularly advantageous in that a more efficient separation of that solid material from the partially soluble organic component is obtained.  The improved separation efficiency can be utilized to either lower separation cost and/or to affect a more complete separation in order to obtain a solid material with a lower residual amount of the organic component.

Title: Turbine nozzle, and a method of varying the power of same
Inventor: KIMBERLIN ROBERT R
IPC: F01D9/04
Filed: 1990-09-06
Granted: 1994-12-13
Abstract: Docket No. 0639-IR-TH     ABSTRACT OF THE DISCLOSURE      The nozzle has a full complement of blades, for use, for example, in a compressed-air turbine. However, a pair of peripheral walls, at opposite sides of the nozzle platform block nozzle blade groups.  The walls prevent fluid flow through those blade groups and, consequently, the nozzle has limited power.  The method teaches the machining away of as much of the walls as is necessary to enhance the power of the nozzle by exposing more of the nozzle blades to free fluid flow therethrough. By providing such walled, fully bladed nozzles, and removing portions of the walls, one can meet any power requirement, from full power to any practical minimum; by removing the walls entirely, or removing only a minor portion of each, respectively.

Granted: 1995-10-10
Abstract: A process, system and pressure chamber for the automated sterilization of articles, particularly medical or dental instruments is disclosed, which is simple to use and economically efficient by comparison with conventional autoclaves and steam sterilizing system.  Steam is generated by the pulsed injection of a controlled quantity of water into a heated boiler whenever it runs dry.  The boiler is coupled in a closed-loop system to a relatively small pressure chamber in the form of a cassette that is readily inserted and removed from a holder comprising means for connecting the chamber to a steam inlet conduit and a venting conduit, the latter being closed off during pressurization of the chamber.  By automated monitoring of the boiler and chamber temperatures, conditions in the chamber are measured and the boiler and valves in the system controlled to effect a sterilization cycle.

Title: Method for removing hydrogen fluoride from mixtures comprising aromatic ketones
Inventor: CURTIS THOMAS A
IPC: C07C51/60
Filed: 1990-11-20
Granted: 2002-09-10
Abstract: A method is provided for separating hydrogen fluoride (HF) from a mixture comprising HF complexed with an aromatic ketone in which the keto carbon atom is directly bonded to an aromatic ring carbon atom, e.g., 4-isobutylacetophenone, by adding a carboxylic acid anhydride, e.g., acetic anhydride, to the mixture while maintaining the mixture at conditions sufficient to sustain a reaction between the anhydride and the HF to form the corresponding acyl fluoride, e.g., acetyl fluoride,  and carboxylic acid, e.g., acetic acid, and separating the acyl fluoride from the mixture. The method is conveniently carried out in a stripping column near the top of which the mixture comprising aromatic ketone and HF is fed and below which the anhydride is fed. Between these feed points, the uncomplexed HF is stripped from the mixture, while below the anhydride feed point or points, the anhydride reacts with the complexed HF to form the acyl fluoride which is stripped from the mixture, and the carboxylic acid. The separation method may be integrated with the production of the aromatic ketone by the Friedel-Crafts acylation of an aromatic compound e.g., isobutylbenzene with an acyl fluoride, a carboxylic acid anhydride, a free carboxylic acid, or a mixture of the foregoing reactants, using an excess of HF as catalyst, to produce the mixture comprising aromatic ketone and HF to be separated, and to which the separated HF and in some cases the acyl fluoride may be recycled.
