Abstract: For an agricultural implement a distributor for feeding seed and/or fertilizer from an air duct to a series of distributor tubes leading to planter units in which the air-entrained seed and/or fertilizer is separated in the distributor to pass some air continuously to the distributor tubes and the remaining air and the seed and/or fertilizer is directed by a rotating deflector to flow sequentially into the series of distributor tubes.

Abstract: Granular spreader apparatus for easy attachment to, and detachment from, a truck equipped with a hopper bed, including dual troughs that each house a continuous conveyor belt that overlies a slotted trough which permits granular material of dissimiliar size and weight, such as fertilizer, herbicide, limestone, and other agricultural particulates of dissimiliar size and weight, to be substantially uniformly distributed from the initial point of deposit at the inboard end of the conveyor belt to the outboard extremity of the conveyor belt.

Abstract: Apparatus and process for introducing solid particles into fluid streams under accurate control. Several embodiments of nozzle apparatus are disclosed utilizing a central fluid orifice or orifices and peripheral solids orifices for mixing the solids into the fluid stream. When multiple fluid orifices are utilized, an area of lower pressure is formed in the central portion of the combined fluid stream thereby aiding in the mixture of the solids into the fluid stream. A flow shaping nozzle is provided at the exit of the apparatus to increase the mixing of the solids within the fluid jets stream. The flow shaping nozzle may have both axial and radial freedom of movement for forming the fluid-solids stream and self-alignment, respectively. The apparatus and process of this invention, in one preferred embodiment, involves introduction of the solids in the form of a foam into the fluid jet stream.

Abstract: An electromagnetically actuatable valve which serves in particular to inject fuel into the intake tube of internal combustion engines operating with fuel injection. The fuel injection valve includes a valve housing, a shell core with a magnetic winding, and a flat armature which is firmly connected to a valve element having a tubular section and a spherical section. A guide diaphragm attached to the housing engages a guide edge of the flat armature in an elastic manner and guides the flat armature parallel to the end face of the shell core. The coaxial guidance of the spherical section relative to the valve seat is effected by means of guide faces of a guide ring. As a result, the movable valve element can have an elongated embodiment, and the fuel injection can be effected at any desired location of the intake tube, while the valve simultaneously requires little installation space.

Abstract: A magnetic valve is proposed, in particular a fuel injection valve for internal combustion engines, which has a valve housing, a conductor coil mounted on a core of ferromagnetic material, and an armature which carries a valve body cooperating with a valve seat. The core has an inner cylinder and an outer cylinder, which are magnetically conductively connected with one another at one end face via a yoke. At the other end face, a circular-annular plate is magnetically conductively connected with the outer cylinder. The magnetic circuit is closed between the circular-annular plate and the inner cylinder via an armature, which has a plate-like element and a hollow cylindrical strut. The strut is located opposite the inner cylinder and with it forms a first air gap. The rim of the plate-like element of the armature is located opposite the circular-annular plate and with it forms a second air gap.

Abstract: A variable lift sprinkler unit includes a support member for attachment to a stationary water supply line with a first rotatable member mounted on the support member for rotation about a generally vertical axis and a second rotatable member rotatably mounted on the first rotatable member for rotation about an axis at an angle to the first member with the sprinkler nozzle carried by the second member such that the angle of the nozzle relative to the horizon continues to change during rotation of the unit with means for rotating the second rotatable member with respect to the first rotatable member during rotation thereof relative to the support member.

Abstract: Nozzle for use with a non-aspirated fire-fighting medium capable of a selection of two rates of flow and two modes of spray control.

Abstract: A fuel injection nozzle for an internal combustion engine includes a hollow nozzle body and a valve member liftably disposed in the nozzle body. The nozzle body has an orifice extending from the inside to the outside thereof. The valve member closes and opens the inner end of the orifice in accordance with lift of the valve member. Fuel can flow through the orifice to be injected into the engine when the valve member opens the inner end of the orifice. A nozzle geometry causes the rate of fuel injection to increase through a plateau as the valve member is lifted.

Abstract: A fire hose nozzle assembly employing separable receiver and nozzle sections which are releasably retained in assembled relation by a removable fastener to permit rapid disassembly and reassembly at the scene of a fire in order to remove accumulated debris and other foreign material from the interior of the nozzle assembly so that normal operation can be rapidly and easily restored. The shiftable valve member and valve seat of a flow control and shut-off valve assembly are respectively mounted in the receiver and nozzle sections of the nozzle assembly. Movement of the valve member toward and away from its seat to vary the characteristics of the flow from the nozzle is achieved by a bail-type control handle that is pivotally mounted on the housing of the receiver section.

Abstract: A constant pressure nozzle having a pressure-responsive baffle head movable toward and away from a throat element so as to define a discharge orifice. The throat being movably mounted for retraction by external control means to a debris-flushing position, but means being provided to maintain the throat in a fixed position during normal operation of the nozzle.

Abstract: An injection nozzle for injecting two different fuels sequentially into the combustion chamber of an internal combustion engine, for instance ignition fuel and main fuel, is proposed. A relief valve is arranged in the main fuel line, and this relief valve creates a relief space between two injection operations. This relief volume is then filled by the ignition fuel. The relief valve essentially includes a spring-loaded piston which is installed in the main fuel line.

Abstract: An electromagnetic unit fuel injector for use in a diesel engine includes a housing having a bushing with an externally actuated plunger reciprocable therein to define a pump chamber open at one end for the discharge of fuel to a spring biased, pressure actuated fuel injection nozzle. The pump chamber is connected to a supply and spill chamber means via flow-through solenoid actuated, normally open, hollow pressure sensitive valve to permit the ingress and egress of fuel. The supply and spill chamber means adjacent to the head of the valve is in flow communication with a pressure equalization and spring chamber means at the opposite end of the valve via a passage through the valve and these chambers are in direct flow communication with a source of fuel at a relatively low supply pressure.
