Abstract: Apparatus for handling materials using a ball bearing mounted table. It includes a table having a horizontal plate (1) on which ball bearings (2) of the same diameter roll freely, thus enabling a load (C) to be displaced. The load (C) can be immobilized by supports (7 and 8) passing into passage (3) drilled in plate (1).

Abstract: A multidirectional thrust-vectoring device for a nozzle, including a fixed and pivoting part. The device includes elastic elements constituting a flexible articulation. The elastic elements form two elastic planes, the first of which is fixed on the fixed part and the second on the pivoting part. The elements are assembled in twos by means of a connecting plate and are distributed in two sets of two elements each on the periphery of the nozzle. Jacks associated with each two-set group allow the nozzle to be turned in the direction desired.

Abstract: A spreader nozzle for granular material in which the material is discharged through a grille of horizontal bars forming openings of length to height ratio such that the material will not flow through the openings under the static head of the material but will flow freely through the openings when the grille is vibrated.

Abstract: A reversible air seal construction for a carrier used in a pneumatic tube system, for use on a carrier of the type having a pair of air seal rings surrounding the carrier body spaced from each other and from the ends of the carrier. The reversibility is accomplished by means of spacers that may be positioned either outside of or between the two air seal rings so that two distinct spacings may be accomplished between the two air seal rings. The positioning of the spacer relative to the air seal ring is facilitated by means of an end adapter unit carrying a closure construction and arrangement for an open end of the tubular material-conveying carrier for the pneumatic tube system. The adapter unit houses a pivot mechanism including a cam member integrally molded with and forming circumferential axis of rotation for a disclike end cap which forms the closure for the tubular material-conveying carrier.

The flap assemblies are pivotable to permit variation in the size and shape of the opening. The nozzle includes actuation means having an output and pivoting means for transforming the output into pivotal movement of the flap assemblies. Cams are included on the flap assemblies to provide at least a portion of the pivotal movement.

Abstract: An injection valve comprising a hollow casing containing an electromagnetic winding connected to a source of electric pulses, an armature in the casing near the winding, a likewise hollow nozzle held by the casing so as to extend therein for a length defined by the geometrical requirements of the intake manifold so as suitably to position the fuel discharge aperture at the front end of the manifold, a closure means having a first end secured to the armature, an external surface coupled to the inner surface of the nozzle, to guide the travel of the closure means, and a second end comprising a conical part adapted to come in contact with a conical seat formed in the nozzle immediately upstream of a bore and bearing a fuel-atomizing deflector which co-operates with the bore in the nozzle to define the fuel discharge aperture, the conical part forming a seal when, under the action of a resilient force, it is in contact with the conical seat whereas it opens the discharge aperture under the action of the magnetic

Abstract: A high flow rate electromagnetic fuel injector valve with a rapid response time is disclosed for utilization in electronic fuel injection systems. The fuel injector valve comprises a stator means and a valve assembly having a self-centering valve member reciprocally mounted in a valve housing. The valve member consists of a ball valve with a semispherical sealing surface connected by a stem to a magnetically attractable cup-shaped armature. The armature is preferably coated with a friction reducing material where it slideably contacts an armature guide bore of the injector valve during its reciprocation. The ball valve of the valve member obturates an exit orifice of the valve housing by sealing against a conical valve seat which has been coined to receive it. Adjacent to the ball valve and conical valve seat interface are vortex generating and metering orifices for the tangential entry of fuel into a swirl chamber of the valve housing.

Abstract: An arrangement for positioning a device for closing and opening a pressure vessel, has a positioning vehicle arranged to carry the device, and a positioning track attachable to the pressure vessel and extending from just above the floor under the pressure vessel to the pressure vessel so that the positioning track guides the positioning vehicle when the latter is displaced from the floor to the pressure vessel to close the latter, and from the pressure vessel back to the floor to open the pressure vessel.

Abstract: The nozzle body of a fuel injection nozzle comprises upper and lower portions which are secured together by welding. This connection is achieved by using the extremity of pin means on the valve needle as a centering element. The surfaces which cooperate with the valve needle at most only need to be equalized.

Abstract: A supporting and guiding stand for a bow-type continuous casting plant comprises supporting segments in which the rollers of the oppositely arranged inner and outer guideways are arranged at a distance from one another. The supporting segments are removable from the arc outer side and are exchangeable. The individual supporting segments are displaceable on rails to accommodating positions, which are provided on the outer side of the arc at different heights, and are preferably offset from each other in step-like manner.

Abstract: A fuel injection valve and a method for manufacturing the fuel injection valve serving to inject easily vaporized fuels are proposed in which the fuel injection valve includes a closing body that controls the fuel outlet and is subjected to a closing force and a nozzle holder secured on the internal combustion engine or on the suction tube. A nozzle body is displaceable within the nozzle holder against a shaped disc until such time as the closing spring supported in the inner area on the shaped disc has an initial stress which corresponds to the valve opening pressure force.

Abstract: A fuel injection nozzle is proposed having two nozzle needles in which the control of the fuel delivered via an inflow line is effected by means of a slide valve embodied as a 3-way valve, which in a preferred embodiment of the invention is simultaneously embodied as a 3-position valve and permits not only the alternative exertion of the fuel pressure upon one of the nozzle needles but also a common pressure exertion of both nozzle needles.

In spite of a small size, the fuel injection valve thus improved can control fuel injection timing and period electromagnetically at a high speed under a high fuel pressure. The valve element can be controlled by a current signal flowing through the solenoid coil, so that the valve element is opened or closed against the force of valve spring.
