Abstract: Disclosed herein is a novel composition of matter which is prepared by subjecting at least one woodlike particle, such as a sawdust particle and preferably selected quantities of sawdust particles to a special treatment. Each particle has a cellular structure including a plurality of interconnected, generally tubular cell walls composed in part of hemicellulose that are subjected to a selectively controlled thermolytic heating above about 280.degree. C. but not above about 380.degree. C. and preferably between 300+ C. and 360.degree. C. to cause the hemicellulose to be converted to an oil-like oleophilic and hydrophobic substance on the cell walls and reduce the thickness of the cell walls to render the particle and particles oleophilic and hydrophobic. The product floats on water, absorbs oil, for absorbing hydrocarbons on the surface of water, and is an improved fuel both without and with the hydrocarbons.

Abstract: In accordance with this invention a method of preparing a leg cut of meat for cooking and serving from which all bones except the shank bone have been removed but wherein the cut retains its general shape of an unboned leg of meat is provided. A generally longitudinal cut is made along the inside surface of the leg into the location of the femur from the top round thereof to the bottom round thereof, as viewed when the leg is hung from a meat hook. Next, a cut is made into the joint between the shank and the femur and the flesh is opened to expose the upper round of the femur. The upper round is engaged with a meat hook. Downward pressure is applied on the femur with the meat hook while a cut is made through the joint. The femur is peeled out of the leg with the meat hook and the bone is removed. The meat cut can then be secured together by tieing or wrapping to hold it in substantially the same shape it had prior to boning.

Abstract: The invention also contemplates a retractable corner mechanism for the inside corner of the concrete form. The mechanism comprises an elongated corner member having first and second perpendicular faces joined along a first edge of each face to form a corner and having form attaching means along a second edge. A concrete form has an end attached to each of the second edges. Means are provided for sliding the forms relative to the corner member and means is provided for retracting and extending the forms to cause the corner member to be retracted and extended. The forms can be made of plywood or metal and the use of steel is contemplated for the corner members. The retracting and extending means can include an externally threaded rod pivotally connected adjacent the end of one of the concrete forms and an internally threaded member pivotally connected adjacent the end of the other of the concrete forms and treadably received on the rod.

Abstract: A harmonic traction motor for converting linear motion to rotational motion. A driven shaft is surrounded by the annulus of a shaft driving member having a circumference slightly larger than the circumference of the shaft. At least two actuating devices are connected between the support and the driving member at 90.degree. with respect to each other and sequentially energized to cause the annulus to exert a force around the shaft in a hypocycloidic motion. This motor has high torque, high stiffness, zero backlash and small volume and can be operated in a stepping mode and can be used as a brake or clutch, if desired.

Abstract: A channel section is of generally U-shaped cross-section and is made from glass fibre reinforced concrete. The section can be thin and light and easily man-handled. In order to provide the section with sufficient rigidity during the setting of a concrete back fill around the section, a framework of reinforcing bars is provided spaced from the reinforced concrete channel member by tie bars. The reinforcing bars and tie bars form a rigid composite structure with the fibre reinforced concrete member which keeps the member rigid while the concrete back fill is drying and which forms a reinforcing structure in the concrete after drying.

Abstract: Appendicitis can be detected by determining a threshold presence of the urinary pigment uroerythrin, in the urine of persons suspected of having appendicitis. The threshold presence of uroerythrin can be determined by precipitation of a sediment having a pink to red color. Additional qualitative, semiquantitative, or quantitative methods including HPLC (high pressure liquid chromatography), TLC (thin layer chromatography), radioimmunoassay, colorimetric tests, NMR (nuclear magnetic resonance), mass spectrometry, electrophoresis, monoclonal antibody tests, and other enzymatic tests may also be employed to measure uroerythrin levels.

Abstract: A photometric analyzer for measuring differential total reduced sulfur in a sample gas stream is provided. It includes a supply for a sulfur bearing gas sample, an oven having an inlet connected to the supply for converting TRS to SO.sub.2 and an outlet through which the gas sample is discharged. A valve is connected to the outlet of the oven. An SO.sub.2 bypass line is connected between the supply and the valve. A sample cell with transparent ends has an inlet adjacent one end connected to the valve for alternately receiving sample gas from either the oven or the bypass line and has an outlet adjacent the other end. A pump connected to the sample cell outlet draws the gas sample through the sample cell. A light source at the one end of the sample cell directs light of a predetermined wave length through the sample cell. A light sensing device at the other end detects the amount of light passing through the sample cell at any given time and provides an output signal to an analyzer.

Abstract: Apparatus and method are disclosed for forming a loop in a wire that is particularly suited for attaching a wire to a ceiling suspension bracket and allow free swinging movement of the wire on the bracket. The apparatus includes a wire storage and feed bin, support for each wire during the loop forming, a twist member, a control head that moves the wire to form a bend, a drive that rotates the twist member through a selected number of revolutions to twist the bend to form the loop, coils and a tail in the wire. Surface portions of the control head confine the movement of the wire during the formation of the coils and loop. A control circuit for the drive motor causes the motor to turn only a selected number of revolutions to form a selected number of coils. A final positioning assembly causes the twist member to stop at the same position after each loop forming operation.

Abstract: A video endoscope is provided which has an inner cylindrical body member containing the optics and electronics in a manner which is impervious to liquid so that the inner member can be soaked in a disinfectant between uses. An outer rigid cylindrical sheath is provided into which the inner sterilizable and therefore is in a sterile condition at the time of use. The inner body releasably locks into the outer sheath. The outer sheath also includes an accordion shaped sleeve at the proximate end which can be drawn down around the trailing cables containing the optics and electronics so that the entire endoscope is sterile for use within the operating room. After use, the inner body member can be removed and the outer sheath can be disposed of or it can be resterilized by heat for use at a subsequent time.
