Abstract: A cultivating machine has a row of soil working members that are driven to rotate about upwardly extending axes. Each member includes an elongated support and the opposite ends of the support each have downwardly extending arms with tine holders in which tines are secured. Each arm is hollow and receives the upper end of a holder that, in turn, receives a tine fastening portion. The arms serve to position the active portions of the tines substantially below their support and the support is thus positioned above ground debris and obstructions.

Abstract: A fluid bearing, which is an aerostatic bearing, wherein one of the surfaces which determine the bearing gap is compliant, so that the geometry of the bearing gap may increase upon increasing load. The notion "compliant" stands for surfaces that are clamped at one point and that are displaceable at a remote point by deformation of the surface, such as steel membranes for thrust bearings, as well as for surfaces that are not deformable but that may pivot about a given point, such as bearing sleeves for rotatable shafts. By the application of compensation the bearing stiffness may be increased.

Abstract: A threaded cap screwed into the piston head with a sealed joint to a sleeve tube open and flanged at the other end are provided to encase the clamping screws that fasten the piston head and the upper piston body member and lower piston body member together. The casing thus formed shields the screws from possibly corrosive coolant that under operating conditions could work through the joints between the parts of a composite piston in spite of the clamping pressure of the screws. Each screw is screwed into the threaded cap at the piston head end and its head or a nut bears on the flange of the sleeve tube at the other end. The screws and their protective casings fit within bores in an annular strut forming a large part of the upper piston body member that butts against a low annular ridge on the underside of the piston head into which the end caps of the screw casings are screwed.

Abstract: An appointment calendar comprises a ring-type binder, at least one page having a pocket and a flap which partially slips into the pocket, and an insertion having two leaves, one of the leaves being received in the pocket to hold the insertion in place in the calendar and the other leaf, which contains printed promotional, decorative or informative matter, overlying the pocket so that the printed matter is visible. The pocket is closed along all margins except along an opening adjacent the edge of the page that is engaged in the binder. The binder rings engage the flap and a part of the page which is non-pocketed but do not engage the pocket or the insertion.

Abstract: Diazotype copies are produced from one-component diazotype material in a practically dry state without adversely affecting their feel or the speed of development. The diazotype material comprises a support and a light-sensitive surface layer having an average maximum thickness of not more than 8 micrometers and comprising 0.2-2 milligram molecules of one or more diazo compounds, which, in vitro, couple more actively than 4-diazo-2-chloro-N.N.-diethylaniline. After imagewise exposure the copy is developed by applying to the light-sensitive surface of the diazotype material a quantity amounting to 1.5 to 4.5 cm.sup.3 /m.sup.2 of an aqueous, buffered solution, which is at a pH of between 5.5 and 7 and which comprises per liter 0.1-0.6 g.mol of azocoupling component, consisting for at least 50% by weight of phloroglucinol and 1-3 g. equivalents of buffer salt. The diazo layer advantageously is formed by spreading 2-8 cm.sup.3 of sensitizing solution of adapted concentration onto the support.

Abstract: The present shaft coupling is intended for releasably linking two or more vices to each other in a torque transmitting manner. The devices may, for example, be turbines each of which has a shaft. Two bearing mounts are provided for one of the shafts, but only one bearing mount is provided for the other shaft at its end remote from the coupling. The coupling between the two shafts is formed by inserting a non-circular end portion of one shaft in a corresponding non-circular aperture in the end of the other shaft. An axially extending bolt firmly clamps the two shafts together in the axial direction. One or both of the shafts may be hollow. The non-circular profiles of the shafts may be splined, or have a polygonal profile, and the polygonal profile may be tapered. A polygonal profile as used herein may be one with only three sides.

Abstract: In a system for use in helicopter navigation antennas are carried at the e ends of each of the blades of the rotor of the helicopter. Radio waves transmitted by a beacon at a known location on the ground are received by the antennas and phase modulated by their rotation. On the rotor the signals are amplified and mixed with oscillations from local oscillators and are detected with the aid of reference signals from the local oscillators. By means of slip rings and contact brushes the signals are introduced into the body of the helicopter where they are first multiplied with each other and then filtered so as to produce phase-modulated signals with a carrier suppressed which are supplied to an electroluminescent diode illuminating a rotating-disc light modulator with a light-transmitting function which is analogous to the phase modulation of the signals received by the antennas. The light beam passing through the disc is integrated in a vidicon and displayed on a screen.
