Abstract: A centrifugal separator for separating contaminants from contaminated oil has an outer casing (10, 11) and a rotor (20) within that casing mounted for rotation about a vertical axis. Oil under pressure enters the rotor at one end and at the other end exits through jets (78) into a chamber within the casing which is normally filled with air. As the jets of oil impinge upon the inner wall of the casing, a small amount of air becomes entrained in the oil and as the oil flows to a sump, the air is gradually removed from the interior of the casing. In order to prevent a build-up of oil within the casing, which could interfere with rotation of the rotor (20), air under pressure is supplied to the interior of the casing by means of a float-operated valve member (113) so that while the valve member is normally closed, any increase in the oil level will cause the float (124) to rise with that oil level and thereby open the valve (113) to allow additional air to enter into the interior of the casing.

Abstract: A fitting for connecting two structural components. The fitting includes a locking device mounted on the first structural component and a support device mounted on the second structural component. A rotary member in the support device defines circumferentially extending conical surface against which the front end of the locking device is pressed when the two fitting devices are connected. The force exerted by the front end of the locking device causes the rotary member to be turned. The rotary member has a helical end face which is initially outside of the range of travel of the locking device. Upon turning of the rotary member, the helical end face comes into engagement with a countersurface of the locking device. The resulting connection can only be released by means of a tool. The structural components are pressed tightly together by a further turning of the rotary member. A piece of furniture composed of several structural components can be initially connected without the aid of a tool and can subsequently be tightened after the piece of furniture has been assembled. The fitting makes possible the connection of structural components where the tolerances in assembling the fitting devices are inaccurate or have been exceeded.

Abstract: A method for cultivating plantable soils, more particularly forest soils, by breaking-up and working-in plants and parts of plants lying upon the soil, for example leaves, needles, twigs and branches. To this end, a plurality of elements, flexible in all directions, tautened by centrifugal force, and secured to a shaft, are caused to rotate by the said shaft, the radius of rotation of the ends of the said elements being greater than the selected distance between the axis of rotation of the shaft and the surface of the ground. In order to be able to mechanically cultivate larger areas of substantially uneven and non-homogeneous forest soils, the horizontal axis of rotation of the shaft is also subjected to an oscillating pivoting motion about a vertical axis, the axis of rotation of the shaft being kept substantially radial to the pivot-axis and being moved in a circle which is parallel to the surface of the ground. Arranged upon the vehicle is a superstructure which is adapted to rotate in relation to the said chassis and upon which the shaft is mounted substantially radially to the pivot-axis. The superstructure and the shaft are motor-driven.

Abstract: A digital timing signal generator and voltage regulator circuit is provided. In one embodiment the circuit includes a delay line. The delay line operating voltage is derived from digitally encoded power/timing signals transmitted by an isolated logic control circuit. The delay line receives and propagates the digitally encoded signals. Outputs of selected stages of the delay line are tapped to provide multiphasic timing signals for use by associated logic circuits. A plurality of gates having inputs connected to various stages of the delay line receive selected timing signals as they propagate along the delay line. Increases in the operating voltage cause the selected timing signals to sequentially activate the gates. The output of each activated gate then goes high and current flows through an associated load resistor connected between the output of the gate and ground to continuously load the supply voltage and thereby regulate it. In variations of this embodiment, two and three levels of gates and load resistors are provided to progressively load the supply voltage and thereby provide additional regulation thereof. In another embodiment, a ring-oscillator comprised of CMOS inverters generates the timing signals. The ring oscillator consumes current in approximately a square relationship with increases in its supply voltage and thereby regulates the voltage.

Abstract: An analytical method for determining the relative amount of a particular hemoglobin derivative, e.g., glycated hemoglobin, in a blood sample wherein the amounts of both total hemoglobin and the hemoglobin derivative are measured and related mathematically, e.g., as a percentage. The blood sample is treated with the combination of a thiocyanate salt and an oxidant to denature the hemoglobin in the sample and to convert hemoglobin to met-hemoglobin. Met-hemoglobin is measured spectrophotometrically to give the amount of total hemoglobin present, and the denatured hemoglobin derivative can be distinguished and measured by immunoassay. The presence of the oxidant in the denaturant solution has been found to increase the rate of denaturation of hemoglobin thereby reducing the overall assay time and improving the reliability of the determination.
