Abstract: A measuring technique and method are provided to simultaneously determine the positions of the surfaces of slag and metal bath in metallurgical processes. In the metallurgical process industry, e.g. in converter processes, it is important to measure the thickness of the layer of slag on top of the metal bath as well as determine the actual volume of metal in order to determine the weight of the charge. A large number of various methods have been tried, but no method is known to result in fast and accurate measurements of both surfaces from a distance and without mechanical means. The herein presented invention describe a method whereby radio waves are transmitted over a frequency band perpendicular towards the surfaces and how a receiver is used to compare the phase of the reflected waves relative the transmitted wave. The phase-change is measured for a number of frequency channels and a transform is then used to transform from the frequency space to the time delay space which gives the positions. The method is suitable for measuring overlapping surfaces at large distances from the reference level and which arc separated by large distances.  The estimated errors of the method are as low as 2 mm. If an interferometer is used as antenna then the data will also be sampled in the aperture plane and the three dimensional structure of the surfaces can be reconstructed.

Abstract: Multi-functional materials are classified into those which have a photocatalytic layer 2 with a photocata- lytic function directly disposed on the surface of a base 1 and those which have a photocatalytic layer 2 with a photo- catalytic function disposed on the surface of a base 1 through a binder layer 6 interposed therebetween. Photo- catalytic particles of the photocatalytic layer 2 are joined together by a surface energy or solid-state sintering. The photocatalytic layer 2 may have a structure in which fine particles fill interstices defined between photocatalytic particles or a structure in which no fine particles fill interstices defined between photocatalytic particles. A metal such as Ag, Pt, or the like may be fixed or not fixed to surfaces of the photocatalytic particles.

Title: Down-pressure system for agricultural implement
Inventor: HENRY JAMES WAYNE
IPC: A01B73/04
Filed: 1995-11-29
Granted: 2005-08-16
Abstract: The implement has a folding tool-bar, with a main section and wings. Hydraulic rams press the wings downwards relative to the main section during operation.  Another ram presses the main-section downwards, reacting the force against a relatively weighty component, such as a air-cart. During non-operation, a carriage wheel is lowered, which raises the main section of the tool-bar off the ground. The wings also are raised clear of the ground. A sensor detects the position of the carriage wheel, and blocks movement of the wings downwards when the carriage wheel is lowered.

Title: Filtering method and apparatus
Inventor: ENGDAHL HOLGER
IPC: B01D29/50
Filed: 1994-10-27
Granted: 2001-10-30
Abstract: The present invention relates to a filtering method, in which the suspension to be filtered is passed into contact with the filtering surface of the filter element, whereby due to the pressure difference prevailing across the filtering surface the filtrate flows through the filtering surface and separated solids substantially remain in the sus- pension. According to the invention the suspen- sion to be filtered is passed to flow downwards along the filtering surface, whereby the filtering through the filtration surface takes place from the falling film and the separated solids are dis- charged with the falling film without forming a harmful solids layer on the filtering surface. An even liquid film falling on the filtering surface is generated by recirculating suspension from the bottom of the filter to the upper part of the filter element. The invention also relates to an ap- paratus for realizing the method, which may be applied especially for clarifying green liquor.

Abstract: A medicament injection apparatus for subcutaneous or intramuscular delivery of a medicament conceals the needle behind a needle shroud. On apparatus activation, the needle is trust forward, pushing the ne edle tip outside the needle shroud with enough force to puncture the skin. The needle is thus automatically introduced into the tissue at the proper needle skin orientation. In the same action, the apparatus automatically dispenses an accurate pre-set dose. The dose can be set by a m anual, variable dosing assembly or by an automatic dosin g assembly. The automatic dosing assembly includes a safety mechanism preventi ng the pre-set dose from being changed except by a docto r or patient using a special wrench or tool.

Abstract: In the manufacture of an insulating unit, a spacer frame having a pair of outer legs and a base connected to provide a U-shaped cross section has one of the pair of legs adhered to marginal edges of a major surface of a first glass sheet by a layer of a moisture-impervious sealant.  An elongated side of the spacer frame adhered to the glass sheets moves out of alignment i.e. the plane containing the base of the spacer frame and the plane containing the major surface of the first sheet are not perpendicular to one another.  Magnetic forces are applied to the base to maintain the elongated side of the spacer frame in alignment i.e. the plane containing the base of the spacer frame is perpendicular to the plane containing the major surface of the first glass.  Thereafter, a second glass sheet is adhered to the other outer leg of the spacer frame by a layer of moisture impervious sealant.  After the sheets and the spacer frame are assembled, the sheets are urged toward one another to flow the sealant to seal the space between the sheets.

Abstract: A rifle harness which comprises a belt, an elbow rest having opposite ends, and a strap having opposite ends. One end of the elbow rest is for receiving an elbow of a human being, or adjacent parts of an upper limb adjacent to the elbow. The other end of the elbow rest, is mounted and adjoining the belt. One of the ends of the strap is mounted to hold the belt, adjacent to one side of the elbow rest. The other end of the strap is mounted to hold the belt, adjacent to a side opposite the one side of the elbow rest. Thus the strap is for running from one of the ends holding the belt, for diagonally crossing up the back of that human being, running over the shoulder joining the other upper limb, and diagonally crossing down the thorax, to finally hold the belt, adjacent to a side opposite the one side of the elbow rest. With this harness, shooting is more reliable.

Abstract: There is disclosed a microwave oven  including a main body constituting a cooking chamber; a door having a pivot pin and an upwardly-projected rod adjacent to the pivot pin and serving to open and close a front opening of the main body; and a hinge member integrally formed to have a pivot hole into which the pivot pin is rotatably fitted,  a stopper formed to transversely come into contact with the rod, and a slit for accommodating a flank of the door when the door is opened to the maximum. The hinge member also includes  a door-connecting section, a body-connecting section, and an inclined section. Such an integrally-formed hinge member prevents the deformation of the hinge member and generation of a gap between the door and the main body of the microwave oven whereby the reliability of microwave ovens of being such a construction can be enhanced.

Abstract: A low power regenerative feedback device (301) and method automatically increases bias current during positive large-signal slewing, enabling output to change faster. The device includes a voltage transforming unit (302), adaptive regenerative feedback circuitry (304) and an output stage (309). When the device is not in a positive slew, bias currents are unchanged, providing a low standby current. Since regenerative feedback is internal and automatic to the device, current is increased only for the device driving an active column of an LCD panel. Thus, the present invention is power efficient. In addition, the AC response of the device is preserved because the device utilizes a regenerative feedback circuit (304) that does not add appreciable excess phase shift. The device achieves an output that switches readily from positive supply to negative supply.
