Abstract: ABSTRACT          "METHOD AND APPARATUS FOR ADDING LIQUID ALLOYING INGREDIENT TO MOLTEN STEEL"    A descending stream of molten metal is directed from a ladle into a bath of molten metal in a tundish. Molten alloying ingredient is added to the molten metal, either directly to the descending stream within a shroud, or it is injected into the bath, through a side-wall of the tundish, at a region of turbulence.  The molten alloying ingredient is protected from the atmos-phere outside the tundish.

Abstract: An ultrasound brain lesioning system with ultrasound, CT or MRI site localization includes a skull fixation apparatus, a position data translating fixture and a computer-controlled ultrasound transducer.  The skull fixation apparatus is utilized in combination with ultrasound, CT or MRI scan transparencies and with a digitizing tablet in order to transfer transparency data both as to skull fixation benchmarks and tumor locations into a computer.  The transducer is cooperatively arranged with the translating system such that the benchmarks of the skull fixation apparatus are utilized to derive X, Y and Z linear coordinates and two rotary coordinates which are at right angles to one another which are also input into the computer such that the computer is then capable of automatically driving the transducer and positioning it at the appropriate location for producing volume lesions in the brain at the site of the identified brain tumors or other selected tissues.

Abstract: Abstract of the Disclosure A method and device for inspecting the internal cross-sectional shape of pipes, and particularly of sewer pipes.  A mandrel is inserted into the pipe.  The mandrel may include an elastomeric member providing a fluid seal engaging the internal pipe surface.  The mandrel also has a retrieval cord attached thereto and trailing therebehind.  A plug member is provided behind the mandrel, which may be inflatably expanded to define a second fluid seal with the pipe.  The space between the pipe and the two fluid seals is pressurized, such as with compressed air, causing the mandrel to advance along the pipe, pulling the retrieval cord as it advances.  The mandrel's advancement will be stopped by a sufficiently large deformation.  Thereafter, the mandrel is retrieved by pulling on the retrieval cord.   In one embodiment of the device, a mandrel and elastomeric member combination is provided that is capable of modification to accommodate various diameter pipes.  In addition, an elastomeric member is disclosed which is a single piece diaphragm for engagement with the mandrel.

Abstract: ABSTRACT         This  invention relates to a novel method of continuously leaching ligin or hemicellulose and lignin from steam pretreated lignocellulosic material as the starting substrate.   In the continuous leach of lignin, the starting substrate has first had the hemicellulose removed therefrom and is then mixed with a concentrated alkali solution, such as sodium hydroxide,  to adjust its pH within a range from 10.0 to 13Ø  The pH adjusted substrate is then continuously leached of its lignin by an alkali solvent, such as sodium hydroxide, moving in counter-flow so that the lignin extract and the now hemicellulose and lignin depleted material can be separately recovered.  The preconditioning of the substrate undergoing lignin leaching avoids the precipitation of lignin out of the lignin extract at its forward counter-flow interface with the substrate.   The continuous extraction of hemicellulose advantageously takes place upstream of the lignin leaching operation and again involves the movement of hemicellulose leaching solvent, such as water, moving in counter-flow direction to that of the starting substrate. Using a counter-current screw extractor in each leaching operation, high concentrations of hemicellulose and lignin in the extracts can be obtained and are superior in yield when compared to single batch leaching techniques.

Abstract: Abstract of the Disclosure A filler for use in chromatography comprises porous spherical grains of poly(.alpha.-amino acid). The spherical grains can be produced by a method which comprises the steps of preparing a solution of hydrophobic poly(.alpha.-amino acid) such as poly n-leucine dissolved in an organic solvent containing an additive;   adding the solution to an aqueous medium and agitating the medium so as to obtain a dispersion of the spherical grains of the poly(.alpha.-amino acid) dispersed in the aqueous medium while evaporating the organic solvent;  taking out the spherical grains of polyamino acid from the disper-sion and removing the additive from the grains.  The additive is noncompatible with the organic solvent in which the poly (.alpha.-amino acid) is dissolved,  and has a higher boiling point than those of the organic solvent and the aqueous medium.

Abstract: A method of manufacturing hollow furniture parts, such as table legs comprises conveying wooden laminae to a work station (2) to form the furniture parts. The number of wooden laminae (6a min , 6b min , 6c min , 6d min ) conveyed to a modelling unit provided with polygonally, preferably squarely arranged guide surfaces (2a min , 2b min , 2c min , 2d min ) corresponds to the number of said guide surfaces (2a min , 2b min , 2c min , 2d min ). The wooden laminae slide across the guide surfaces (2a min , 2b min , 2c min , 2d min ) while abutting said surfaces. The longitudinal edges of the individual lamina are undercut so that the laminae form a prismatic, hollow tube (7) subsequent to being assembled. The side surfaces of said tube (7) are mitred along the longitudinal edges of the tube, and the wooden laminae (6a min -6d min ) are glued together in pairs by means of a fast-drying glue applied shortly before the laminae reach the modelling unit (2). Support and/or end blocks (18, 19) are then optionally inserted in and glued to the inside of the prismatic tube (7). Finally the tube (7) is cut into small pieces corresponding to the furniture parts. This method enables the manufacture of furniture parts with prismatic shape in a simple manner while avoiding such steps in the pocess resulting in considerable inner stresses in the wood.

Abstract: This invention relates to a belt printing mechanism with parallel mounted endless type belts which carry on their exterior surface print types. These type belts extend around an adjustment wheel and a plurality of star wheels where the star wheels are rotatable about a shaft where each star wheel has four corners. A catch mechanism is held under tension against the star wheels and holds these in predetermined detent positions to prevent free rotation of the star wheels. When printing multi-character symbols, the selected print types of adjacent type belts must be brought into predetermined printing positions. In order to assure a clean print copy, care must be taken that the print types rest in the exact same line height. In order to accomplish this, the catch mechanism for each star wheel is provided with a spring tongue which touches at least two separated points of the perimeter of its associated star wheel between two adjacent corners thereof. The plane of each spring tongue with respect to the plane in which its associated star wheel rotates is an acute angle. When the type belts are adjusted, the catch mechanism generates pressures which are clearly recognizable by the operator and which simplify the procedure of bringing the print types into their predetermined printing positions.

Abstract: A ring encircles produce placed on a work table. Tie ribbon is fed by pressure rollers around the inner periphery of the ring to form a complete loop. A first gripper clamps and retains the free end of the ribbon against a second gripper. The pressure rollers operate in reverse retracting excess ribbon about the produce. A friction clutch, operative only for reverse ribbon feeding, allows for ribbon slippage as the ribbon tightens around the produce. Then the second gripper clamps the other end of the ribbon against a twister head and a twister mechanism rotates the clamped ends of the ribbon about a common axis twisting the ribbon ends together. Shearing edges sever the engaged ribbon from a ribbon supply during twisting. The grippers and twister mechanism are at ends of concentric support rods and tubes, and the grippers in clamping move along the rotational axis of the twister mechanism. Axial gripper motion is provided by cylinder valves having pistons concentric with and supported by the gripper support rod or tube and acting, respectively at the ends of the gripper supports away from the tie ribbon. Rack and pinion mechanisms provide rotation of the twister mechanism and forward and reverse feeding of the ribbon. All components are pneumatically driven. The design accommodates normal wear and temperature variations without adjustment.
