Abstract: INVENTOR:   SAMUEL STAUB            INVENTION:  APPARATUS FOR WINDING UP PRINTED PRODUCTS             ARRIVING IN IMBRICATED FORMATION              ABSTRACT OF THE DISCLOSURE     The printed products to be wound up are delivered by one belt conveyor of a conveying arrangement.  The latter comprises two belt conveyors which conjointly  form a conveying channel with a defined inlet and outlet.  Conveyor belts of both of these two belt conveyors are guided such that the conveying channel has a curved path directed toward a rotatable winding mandrel.  The conveying arrangement is pivotable about an axis of rotation of a drive drum of the innermost conveyor belt of the two conveyor belts and is pressed against the winding mandrel, respectively against the product coil or wound package forming on the winding mandrel, by a winding strap capable of being placed under tension and which is withdrawn from a winding strap supply roll and runs through a portion of the conveying channel and is connected with the winding mandrel.  A separate contact or pressing mechanism can be foregone. The design of the conveying arrangement permits a compact construction and free choice of the delivery location of the printed products to the winding mandrel.

Abstract: ABSTRACT          The pressure-medium-actuated valve (1) has a pressure medium inlet (11), a pressure medium outlet (12) and a cylinder (2), a piston (24) which is connected to a lid (13) being movable in the cylinder (2).  The piston subdivides the cylinder (2) into a first piston chamber (21) and a second piston chamber (22). Two relief lines (44, 45) each comprising a control valve (441, 451) are connected to the piston chambers (21, 22) and extend to a pressure medium sink.  A first connecting line (41) comprising a control valve (411) extends from the inlet (11) to the first piston chamber (21) and a second connecting line (42) comprising a control valve (421) extends from the inlet (11) to the second piston chamber (22).          A third connecting line (43) is disposed in the wall of the valve body (10) and extends at one end into the first connecting line.  The other end of the third connecting line (43) is connected to the cylinder at a place which, with the piston in the operative position, extends into the second piston chamber and, with the piston in the safety position, extends into the first piston chamber.  The lid can therefore move relatively fast but be retarded shortly before reaching an end position.

Abstract: FOLDING IMPLEMENT FRAME FOR   GRAIN DRILLS AND THE LIKE     Abstract of the Invention A pull-type folding implement,  such as a grain drill has individual and independent radial flotation for each of its drill units such that each unit can rise and fall,  while remaining level, independently of the other, as well as cock and cant independently of the other as may be necessary  to accommodate uneven ground  terrain, yet the units may be folded into compact, fore-and-aft extending transport positions in which ground wheels thereof are retracted off the ground and the units are carried by a main, fore-and-aft carrier frame of the implement.  A third, center unit may be provided between the two outer units and utilizes its own set of ground wheels during both field working and over-the-road travel when the other units are folded in, the center unit likewise having a floating connection with the carrier frame which permits the center unit to rise and fall, cock and cant when experiencing terrain irregularities.  Because the weight of the two outer units is borne entirely by the carrier frame when the outer units are folded in for transport,  a safety interlock is provided which prevents unfolding of the outer units from the carrier frame unless the ground wheels of the outer units have first been lowered into ground engaging positions capable of supporting the load of the outer units.   Special cocked pivot assem-blies coupling the outer units with the central carrier frame cause  the units  to be likewise cocked about their longitudinal axes when folded into the transport position such that depending, outboard extremities of the units are provided with an extra measure of ground clearance at that time.

Abstract: Surface Penetrant Inspection Test Piece Having Varying Thickness Plating Abstract A test specimen has a carefully controlled series of cracks on its surface and is useful for evaluating surface penetrants employed in non-destructive inspection.  A flat brass substrate has a nickel electroplating on one surface, which plating varies in thickness along the length of the panel.  The opposing side of the panel has a multiplicity of grooves which locally concentrate strain in the plating when the panel is bent during manufacture, thus providing a crack associated with each groove. In a preferred embodiment, the texture of the cracked surface varies across the panel in the same direction in which the cracks run, thus enabling evaluation of the usefulness of penetrants in finding different size cracks under different surface finish conditions.

Abstract: ABSTRACT: Projection lens system.     A lens system is provided which is suitable for back-pro-jecting an enlarged image of a TV cathode ray tube (CRT). To achieve a compact cabinet design 1 for such a projection television set, a short projection throw and a wide projection angle are required, to-gether with a wide aperture (F/1) for a bright projected picture and with a definition which may need to be good enough to resolve 1249 line television pictures. The lens system comprises a concave CRT face-plate FP and three lens elements L1, L2, L3. L2 and L3 are each of positive power and L1, most remote from the CRT, is a weak lens. At least one of the element surfaces is aspheric. The powers of the elements are chosen so that -0.20 K < K1 < +0.15 K +0.62 K < K2 < +0.80 K and +0.55 K < K3 < +0.67 K where K1 is the power of the first weak element remote from the object surface, K2 is the power of the second element, K3 is the power of the third element adjacent to the CRT surface and K is the total power of the projection lens. Projection angles upto ? 40 degrees are obtained. (Figures 1 and 2).

Abstract: ABSTRACT           Apparatus for sensing hydrostatic pressure in a fluid, forming a head for a bubble tube for immersion into the fluid.  The head is formed of a plate having a flat lower surface for horizontal disposition within a liquid, a first orifice for introducing a gas under pressure from above the plate whereby the gas can form a bubble under the plate within the liquid.  The effect of the plate is as a surface on which a stable sessile bubble of a variable size can be grown.  This results in a bubble having a substantially increased radius of curvature at its interface, that is, the gas/liquid interface, on the underside of the bubble than previously obtainable.  A pressure gauge measuring the gas pressure in the tube determines the pressure at the end of the tube within the fluid.

Abstract: CROSS LINE RELIEF VALVE MECHANISM     Abstract of the Disclosure A cross  line  relief  valve  mechanism  in-cludes a pair of opposed relief valves contained in a bore  connecting  the  service  passages of  a control valve.   A high  pressure  condition  in  one  of  the service passages acts directly on the main poppet of one of  the relief valves causing  it to become un-seated and communicating the high pressure condition to a zone in the bore between the two relief valves. The high pressure condition in this zone acts on the pilot poppet of the other relief valve causing it to open which results in the unseating of the main pop-pet in that relief valve.   The high pressure condi-tion in one of the service passages thus results in the opening of both valves so as to allow high pres-sure fluid to flow from one service passage to the other in order to obtain a balanced condition.
