Abstract: ARRANGEMENT FOR ENCASING STEEL CONCRETE     CEILINGS PROVIDED WITH TRUSSES                     ABSTRACT OF THE DISCLOSURE      An arrangement for encasing ceilings with trusses in which a framework of four telescopic supports and strengthened by struts, holds casing beams having two sides on which tele-scopic ceiling casing carriers are located.  The framework provides for supporting the casing for the trusses, and at least two trusses are placed a distance apart and adjacent from each other.  Between the casing beams and the supports , beam support carriers are telescoped on both ends and com-bined into a fixed angle frame detachably and tension-proof connected to the supports.  The support carriers, further-more, support abutments bridging a space between the casing tables for the truss casing carriers.  Four intermediate supports are detachably fastened to the beam support carriers, and the casing beams which support the ceiling casing carriers and which are combined with the ceiling casing carriers into a rigid-angle frame, are fastened to the four intermediate supports.  Beam support carriers are made of rectangular pipes with four detachable inserts, and are fixed in relation to the beam support carriers while being movable.  The abutments are movable, moreover, in infinitely variable steps on the beam support carriers for lateral beam casings.  The intermediate supports are fastened to the beam support carriers with infintely variable height adjustment.  The intermediate supports are detachably connected to the casing beams.

Abstract: ABSTRACT OF THE DISCLOSURE           The braking gear has two turnable levers coupled by a spring and carrying brake shoes which engage the disk of the machine to be braked at both sides thereof and a double-acting hydraulic cylinder mechanically connected with the turable levers by means of an articulation double-link memb-er.  The double-link member has a common articulation joint which is connected with the piston rod of the hydraulic cy-linder.  The ends of the articulation double-link member are connected with the levers and are acted upon by the spring, coupling the turnable levers, due to which the levers are reliably fixed both when the braking gear is switched on or off.

Abstract: METHOD AND APPARATUS FOR SHAPING AND PLANING BOARDS     Abstract of the Disclosure A method and apparatus for shaping the edges and planing a surface of elongate boards in a single integrated operation so that the sides and ends thereof are interlock-ingly matched with complementary shapes.  A leading end of each board is moved laterally past a first edge cutting head which cuts a first shape therein.  Then the board is moved longitudinally past the same cutting head such that the same shape is cut in a first side thereof.  After a portion of the first side is cut, one of the faces of the board is planed by a cutting head and, subsequently, the board is moved longitudinally past a second edge cutting head which cuts a shape in the second side of the board complementary to the shape previously cut in the first side. After cutting of the second side of the board is completed, the trailing edge of the board is moved laterally past the second cutting head which shapes the trailing edge similar to the second side so as to be complementary to the shape previously cut in the board's leading edge.  This method is carried out by an apparatus which utilizes only one cutting head to shape two adjacent edges while minimizing the necessary manipu-lation of the board.  The operations are executed by two movable carriages for moving and positioning the boards and a central table housing the cutting heads.  The operations of the carriages, cutting heads and various guide mechanisms are governed by a hybrid control system utilizing pneumatic, hydraulic and electric power transfer and control means.          The apparatus also accepts random length boards, is adjust-able to a variety of graded width boards, and automatically loads raw boards and stacks finished boards.

Abstract: "TURNTABLE SUPPORT STRUCTURE FOR    RADIUS MILLS AND THE LIKE" ABSTRACT OF THE INVENTION              This invention relates to an improved three-point support subassembly for pivoted machine tool turntables that is characterized by a pair of floating pads retained in cavities on the underside of the turntable that slide along the opposed planar surface of a stationary bedplate therebeneath and a ball and socket pivotal connection that allows the turntable to swing on a vertical axis defined by the latter as well as tilt relative thereto.  The stem portion of the pin is journalled for rotation about a vertical axis in the bed-plate while the spherical portion atop said stem is connected to the turntable for conjoint movement in a horizontal plane due to a loose fitting coupling therebetween.  The socket journalling the spherical portion of the pivot pin includes upper and lower segments independently adjustable relative to one another and to the turntable for purposes of levelling the latter.  Adjustable abutments also engage the pads and are used to raise or lower the turntable relative thereto.

Abstract: ABSTRACT         The invention relates to a control circuit for a brushless self-starting D.C. motor of the type having a permanent magnet rotor and stator coils, a magnetic field-dependent component or sensing coil for sensing the position of the rotor, and controllable electronic switches in respective series with the stator coils and the D.C. source.  The switches control current through the stator coils in dependence on the rotary position of the rotor pursuant to magnetic field dependent parameter changes in the sensing coil.  The control circuit is characterized by including an oscillator with an LC resonant circuit of which the inductance is formed by the sensing coil.  The circuit includes a modulator for modulating the oscillation of the oscillator in response to the induction changes brought about in the sensing coil.          The control signals for the switches are derived from the modulated oscillator oscillation because the oscillator frequency is considerably higher than the rotor speed.          The sensing coil is in fixed relation to the stator but has no particular circumferential position relative thereto.  A metallic element is attached to the rotor which turns with the rotor past the sensing coil.  The position of the sensing coil and the metallic element may be chosen at will independently of the stator coils.  The metallic element may consist of soft iron and be attached to an end face of the rotor.  The metallic element may have the shape of a segment and extend over an angle less than 180°     Abstract...continued.   so that with regard to the physical dimensions of the sensing coil, control signals displaced in phase through 180° are derivable from the signal of the sensing coil.

Abstract: A B S T R A C T A waterborne air cushion vehicle is disclosed which has a flat rigid upper rectangular sheet-like platform.  A plurality of flat rigid longi-tudinal walls are attached substantially at right angles to the platform and depend therefrom substantially parallel with the major axis of the platform. The outermost two of the walls are disposed as sidewalls along the respective edges of the platform.  A plurality of longitudinally spaced laterally aligned arrays of flexible trough-shaped skirts are respectively looped with a space therein and fastened via each longitudinal edge thereof with respect to the underside of the platform flush with but independently movable with respect to adjacent pairs of the walls but extendable to a lesser depth than that of the walls.  The vehicle has a source of pressurised air admissible via apertures of fixed size at a relatively higher pressure to the skirts and also admissible at a relatively lower pressure via variable-sized openings remotely controlled and located respectively beneath the platform in communication with open-bottomed air cushion chambers each bounded by an adjacent pair of the skirts and by an adjacent pair of the walls.  The depth of the walls and of the skirts is so related to the flow rate of the air that the vehicle is buoyant upon water with the walls protruding into the water sufficiently to prevent air spillage via the walls when the vehicle is urged longitudinally through the water by propulsion means.  The apertures and the openings are adapted to re-admit by reverse flow at least part of the compressed air in any one of the chambers and its associated skirts independently in response to fugitive deflection of the skirts resulting from turbulence of the water, to thereby inhibit movement of the vehicle about the pitch axis thereof.
