Abstract: Apparatus for cleaning pipelines for beverages has a shuttle valve with a body which is formed with a sleeve for a reciprocable shuttle. The body has a composite inlet for admission of fresh liquid cleaning agent, and an outlet for spent cleaning agent. Bayonet type connections are provided to separably connect the body with two adapters which are disposed at the ends of the sleeve and are separately connectable with the ends of a pipeline to be cleaned. The shuttle has two ports and two channels as well as two smaller-diameter extensions one of which is received in one of the adapters in a first end position and the other of which is received in the other adapter in a second end position of the shuttle.

Abstract: A method and apparatus for applying a magnetic liquid to a moving web by using an extruder head for ejecting the magnetic liquid onto the web. A by-pass line for returning the liquid to a feed source through a changeover valve is provided immediately upstream to the extruder head. The liquid is supplied to the by-pass line through the valve after the extruder head is filled with the liquid before the first starting of the application or the resumption thereof. The position of the valve is shifted at the time of the first starting of the application or the resumption thereof so as to supply the liquid to the head to perform the application.

Abstract: A control valve which can randomly select any one of a plurality of conduits for controlling the flow to a single output port. The valve is comprised of base plate and a cover or bearing plate, which together form a housing having a cavity. A slider or block of the same shape, but slightly smaller than the cavity, is confined in, but may move freely in the cavity to align a port in the base plate with ports in the slider. The slider has a plurality of ports and as the slider is moved from one corner of the cavity to another, the ports in the slider are selectively aligned with the port in the base plate. Fluid conduits may be connected directly to the ports in the slider through an aperture in the bearing plate. Actuators in the walls of the cavity selectively move the slider from corner to corner. The actuators may be driven by any suitable means.

Abstract: A control valve of the type comprising a rotatable distributing member having a distributing surface having a plurality of coaxial ribs intersected by radially extending rib portions projecting on the distributing surface and engaging a smooth surface of a stationary valve body to define therewith a plurality of coaxial part-annular channels for selectively interconnecting selected ones of a plurality of passages bored through the valve body and opening in the smooth surface. The distributing member is retained in engagement with the valve body by a corrugated spring washer clamped between the outer face of the distributing member and a cap or hood member fastened to the valve body, and the spring washer is fastened against rotation relative to the cap member, while the outer face of the distributing member has a plurality of recesses for receiving the corrugations of the spring washer to hold the distributing member in any one of several angular positions.

Abstract: An intake system for an internal combustion engine has been developed to include a translationally movable throttle to cause cross-sectional passage of the intake manifold of the engine cylinders to vary. This throttle utilizes a substantially rigid plate which is pierced with orifices adapted to be connected with each of the intakes corresponding to the various engine cylinders. A movable blade is provided with apertures corresponding in number and spacing to the orifices which contacts with a control and guide means so that the blade is allowed to move parallel to the plate from a running position in which the apertures of the blade are substantially opposite the orifices of the plate to an idle position in which at least the majority of the orifices of the plate are obturated by the blades.
