Abstract: The invention concerns a power take-off apparatus for a tractor. The power take-off apparatus comprises a power take-off (PTO) shaft (1) on which have been disposed two gear wheels (4,5) arranged to be freely rotatable and which operate independent of the speed of rotation of the tractor's traction wheels. The first gear wheel (4) has been arranged to rotate within a high speed range and the second gear wheel (5), within a low speed range. The PTO apparatus furthermore comprises two shaft pins (2,3) alternatively attachable to the PTO shaft (1), of which the first shaft pin (2) is intended for the high speed range and the second shaft pin (3), for the low speed range. When said second shaft pin (3) is attached to the PTO shaft (1), the shift sleeve (12) can be optionally coupled with said second gear wheel (5), but it is prevented from becoming coupled with said first gear wheel (4). When said first shaft pin (2) is connected to the PTO shaft (1), the shift sleeve (12) can be optionally coupled with the first or second gear wheel (4 or 5). On the PTO shaft (1) has furthermore been disposed a third gear wheel (25) arranged to be freely rotatable and arranged to operate at a speed dependent on the speed of rotation of the tractor's traction wheels. The shift sleeve (12) can be optionally coupled with said third gear wheel (25) independent of which one of the shaft pins (2 or 3) has been attached to the PTO shaft (1).

Abstract: A method and apparatus of providing a visual representation of a curve image wherein curve image data is provided by a B-Spline equation computed with a forward difference technique using scaled integer variables. The method provides for the scaling of the initial base matrix computation of the geometry vector coefficients followed by the computation of the forward difference interval coefficients using integer arithmetic. The curve coordinate values for each interval are computed from the forward difference interval coefficient integers descaled by the scaling parameter. By employing integer arithmetic in a divide approximation technique, the use of floating point arithmetic is avoided. The apparatus for producing the visual representation of the curve image includes a computational section that provides for pipelined computations of the forward difference interval coefficients to provide high-speed curve coordinate value computation.

Abstract: Circuits, and methods of using the same, are disclosed for controlling the power supplied to a discharge lamp of the type having a closed inductive loop, such as the resonant ballast circuit for a fluorescent lamp or the inductive ballast loop of a high pressure sodium lamp, wherein the closed inductive loop is operated by an electrical power supply having a d-c input stage and an output power controlled by the switching of a switch means within the power supply itself whereby current flows to the closed inductive loop when the switch means is conductive and no current flows from the power supply to the closed loop when the switch means is non-conductive. The instantaneous current flowing through the switch means itself is sensed and integrated to provide a first signal having a value that is proportional to the actual power being supplied to the closed loop. An error signal is created having a value indicative of the difference between the first signal and a second signal with a value proportional to the desired set point power for the lamp. The switching of the switch means is adjusted in accordance with the value of the error signal, whereby the output power of the power supply is continuously adjusted toward the set point power for controlling the power actually supplied to the lamp circuit irrespective of the parameters of the lamp circuit itself. The disclosed circuits provide for constant power to a high pressure discharge lamp to yield a constant color temperature. Further, the disclosed circuits provide for dimming of the discharge lamp to selective power levels.

Abstract: A pulse oximeter sensor (410) with a light source optimized for low oxygen saturation ranges and for maximizing the immunity to perturbation induced artifact. Preferably, a red (112) and an infrared light source (114) are used, with the red light source (112) having a mean wavelength between 700-790 nm. The infrared light source (114) can have a mean wavelength as in prior art devices used on patients with high saturation. The sensor of the present invention is further optimized by arranging the spacing between the light emitter (112,114) and light detectors (116) to minimize the sensitivity to perturbation induced artifact. The present invention optimizes the chosen wavelengths to achieve a closer matching of the absorption and scattering coefficient products for the red and IR light sources. This optimization gives robust readings in the presence of perturbation artifacts including force variations, tissue variations and variations in the oxygen saturation itself. <IMAGE>

Abstract: A chemically bonded medium is obtained from a resilient organic macromolecular material, in cut elongate of finely divided form (such as grass or peat). The material is dried (3, 4) under conditions permitting escape of water vapour, such that the dried material has a predominantly hydrophobic surface and a water content of not more than 10 % by weight; and then optionally flashed. The surface properties of the dried material are then equilibrated, under conditions inhibiting escape of water vapour and other volatiles, such that the predominantly hydrophobic surface is rendered predominantly hydrophilic. The product is then mixed (5) with a lignosulfonate, with application of heat in an amount sufficient to maintain the lignosulfonate in fluid form, such that the lignosulfonate forms a coating film on the surface. The lignosulfonate is caused to undergo partial polymerisation (6) (typically by heating and/or treatment with oxygen) on the surface of the dried material to produce a flowable, substantially non-resilient and non-tacky, chemically bonded medium. The bonded medium may be stored or shaped (8) under pressure to form agglomerates.
