Abstract: Abstract of the Disclosure This invention relates to a method for manufac-turing alloy comprising:  providing a consumable electrode pair consisting of a pair of spaced-apart electrodes of the same element for each metal element of the alloy; generating an electric arc between the electrodes in a non-oxidizing atmosphere, to melt the consumable electrodes; and allowing molten drops produced by the melting to pass into a mold to form molten metal, and the molten metal cast into an alloy consisting of the metal elements.  The consumable electrodes of each pair may be aligned on an axis, spaced a predetermined distance apart, and in a common horizontal plane above the mold.  The invention allows alloys to be produced from metals having widely different melting points.

Abstract: ABSTRACT OF THE DISCLOSURE A tire changer has the feature of containing vehicle tire/rim assemblies which are caused to explode due to tire overinflation or tire bead failure for any reason.  A tire and rim assembly hold down bar is pivotally attached to the body of the tire changer and is secured in position immediately overlying the tire/rim assembly on the tire changer by engaging a tongue in a buckle assembly mounted on the bar.  The tongue is attached to the end of a web belt which is secured to the body of the tire changer.  Engagement of the tongue in the buckle also actuates an enabling valve in a conduit for transmitting tire inflation air from a pressure source to the tire.  Inflation air may then be provided at will to the tire by actuation of an inflation valve located in the air conduit between the pressure source and the tire.

Granted: 1991-01-02
Abstract: A fastener for maintaining or reinforcing contact between a connector and an electronic circuit includes an element made of a substantially tubular section having spaced apart edges which define a longitudinally extending slit. The element is made of an alloy which has superelasticity and shape memory properties. The fastener is cooled to a temperature below the Martensite temperature and the slit is opened to a width large enough for the insertion of the connector and the flexible electronic circuit and small enough such that the fastener is superelastically deformed at a temperature at or above the Martensite temperature if the width of the slit is held constant. Therefore, the connector and the electronic circuit are fastened with a force, which is substantially constant over time. The result is an electrical connection of improved reliability.

Granted: 1993-05-25
Abstract: Abstract of the Disclosure Method and device for contact-free drying of a paper or board web     or of any other, corresponding continuous web    .  In the drying, both infrared radiation     and drying air jets are used, by means of which said air jets the web     running -through the dryer      is, at  the same time, carried free of contact. The moving web     is first passed into an infrared drying gap, in which a drying energy pulse of relatively short duration is directed at the web    , the power of the said energy pulse being substantially higher than the average drying power of the dryer per unit of area.  After the infrared drying gap, the web     is immediately passed into an airborne web-drying gap , wherein the web     is supported and dried by means of air jets.  Air             is brought into the infrared unit     , which said air, having been heated in the infrared unit     , is passed as replace-ment air and/or drying air for the airborne web-drying unit         or units         placed after the infrared unit.  The air flows             to be passed into the infrared unit     are passed in connection with -the inlet gap     of the web     to both sides of the web so as to make accompanying and sealing jets

Abstract: ABSTRACT OF THE DISCLOSURE An attenuated fiducial replica of the far field pattern of a high energy laser beam is obtained by a system and method wherein a first fraction of an incident high energy beam is deflected from one reflective surface of a holey plate  and the  diffracted orders  of  the beam  are transmitted from the holes to a concave reflector, which reflects diffracted orders toward an opposite reflective surface  of  the holey plate.  A zinc  selenide partially reflective member  is disposed on-axis between  the  rear reflective   surface   and   the   concave   surface   for re-reflecting successive  fractional  portions  of  the  re-flected beam a selected number of times to attenuate the beam converging upon a focal plane from an effective focal distance greater than the physical length of the optical system.

Title: Method for treating polluted material
Inventor: RASMUSSEN ERIK
IPC: C02F1/72
Filed: 1988-02-16
Granted: 1993-11-16
Abstract: ABSTRACT   Polluted material such as industrial waste water or polluted water from other sources, sewage or sewage sludge or other forms of sludge, or polluted soil, is degraded to remove the oxidizable substances therein by subjecting the polluted material to a wet oxidation process.  This process, which occurs in a reactor, decomposes and/or modifies oxidizable substances in the polluted material and optionally improves the filterability of the solids present in the material.  Optionally, the polluted material may be pre-treated to facilitate the wet oxidation process.  The wet oxidation process is performed to the extent that the decomposed and/or modified substances remaining after the wet oxidation process are substantially biodegradable. Optionally, a subsequent substantial removal of heavy metals may be performed.  If necessary, the material may be separated into a solid and liquid phase, and the material or liquid phase may be subjected to a biodegradation process.

Abstract: GRAY 3.0-4/PCT            Inventor:   JOSEPH GRAYZEL    Title:      DIAGONALLY TAPERED, BEVELLED TIP INTRODUCING             CATHETER AND SHEATH AND METHOD FOR INSERTION                       A B S T R A C T      The present invention provides an improved introducing-dilating catheter which may also be applied to facilitate insertion of catheters of all types and functional purposes. The catheter has a tapered portion which is, in turn, connected to a bevelled tip portion to facilitate insertion of the cath-eter into a preexisting puncture aperture.  The bevelled tip portion is finished to remove any points capable of puncturing or any edges capable of injuring the tissues by the application of only a small force.  Indicia means are provided to enable the practitioner using the introduction-dilation catheter to determine the orientation of the tip of the catheter so that the leading point of the bevelled tip will initiate engagement with the vascular puncture cut and enter the vessel in the acute angle formed between the guide wire and the vessel wall. Additionally, after entry of the entire tip, the indicia means allow the introducing catheter to be reoriented so as to keep the bevel parallel to the wall of a vessel.

Abstract: METHOD AND APPARATUS FOR CONTINUOUS PRODUCTION OF           BAGS FROM THERMOPLASTIC FILM                ABSTRACT OF THE DISCLOSURE     A method and apparatus are provided for continuous fabrication of bags from a longitudinally advanced multi-layer thermoplastic film  web fed tangentially onto a rotating drum for carrying out transverse web seam welding and severing, the principal novel feature being provision of preliminary heating carried out across at least part of the width of web at which the final seam and sever is to take place. The preliminary heating step is advantageous where the thickness of film layers to be sealed and severed is not uniform across the width of the web or in which the uniform thickness of the film layers is such that seaming and severing in a single step requires an undesirably long time for continuous high speed production. The method can be adapted for production of bags of different widths.

Title: Polysaccharide/perfluoroalkyl complexes
Inventor: CLARK KIRTLAND P
IPC: C08B37/04

Granted: 1992-09-29
Abstract: Polysacchlride/Perfluoroalkyl Complexes Abstract The instant invention relates to water-soluble anionic polysaccharides bound to perfluoroalkyl cationic surfactants. Polymer complexes are formed which are especially useful for fighting fires of hydrophilic or polar liquids. They have the unique property of forming an impervious gel when foamed with suitable surfactants and projected onto burning liquids. The gelatinous blanket is resistant to the fuel and protects the foam blanket from destruction. Consequently, superior fire-fighting agents can be prepared for fires which are otherwise very difficult to extinguish.
