Abstract: A material spreader includes a hopper having an opening in its bottom through which material flows to a rotatable fan, which is driven from one of a pair of support wheels for the hopper during pushing or pulling of the spreader across the ground, for spreading the material. A gate, which is pivotal about the same axis as the axis about which the fan rotates, has an opening, which is smaller than the opening in the hopper, to control the portion of the opening in the hopper through which the material flows to control the spread pattern produced by rotation of the fan. A shutter, which is disposed beneath the gate, has an opening, which is smaller than the opening in the gate, cooperating with the opening in the gate to control the rate of flow from the hopper. The gate has a first arcuate slot therein within which is disposed a bolt supported by the hopper to limit pivoting of the gate. A wing nut cooperates with the bolt to lock the gate in the desired position without affecting movement of the shutter.

Abstract: A dispensing valve for use on an inverted bottle of fluent imaging material includes a valve cap which can be threaded to the neck of the bottle. A resilient valve plug is carried on a spindle which extends through an opening in the valve cap. A spring compressed between an enlargement on the spindle and a hub in the valve cap biases the valve plug outwardly into sealing engagement with a valve seat at the interior end of the valve cap. The valve is protected from inadvertent opening by a disc-like clip and an overcap. The clip, which has a diametral slot to accommodate the spindle, is held between an end of the spring and the spindle enlargement.

Abstract: A tap operated by a push button which acts to open a valve member which is biassed to the closed position, the valve member being for normal operation of the tap; also operated by the push button, but only on initial operation of the push button, is a plugging means which plugs the inlet of the tap and which after the initial operation remains out of the inlet. The arrangement ensures added protection against oxygen penetrating into a container fitted with the tap and is particularly useful for wine containers where the added protection ensures a longer shelf life. The use of a plugging means fitted tap avoids the necessity of special sealing equipment for the containers in the winery where containers are filled.

Abstract: A dispensing cap for a container. The cap has a tubular body of circular transverse cross-section with a wall closing the top end of the tubular body. An upwardly opening slot is formed in the top end wall and extends across the tubular body with a generally flat wall forming the bottom of the slot. An aperture extends through the bottom of the slot into an area surrounded by the tubular body. A hinge assembly is located in the slot and includes an upstanding member formed on the flat bottom wall of the slot at a location inwardly of the circular perimeter of the tubular body. A flap is integrally connected to the upstanding member of the hinge assembly by a strap. A portion of reduced thickness is formed in the strap to create a hinge at the juncture of the strap and the upstanding member.

Abstract: A drip retainer for preventing residual fluid in a spout from dripping includes a tubular resilient member which is flattened at one end so that opposite walls are biased together. An opposite end of the tubular member is connected in a liquid-tight manner to the spout. A cylindrical clamp is mounted on the flattened portion of the tubular member. A hollow area inside the cylindrical clamp is filled with resilient biasing material. The biasing material, on either side of the flattened portion, urges the tubular member to a flat closed position. When liquid is pumped through the spout under pressure, the liquid urges the flattened portion of the tubular member to an open position. When pressure subsides, the biasing material urges the flattened portion back to its closed position, so that residual fluid clinging to inside walls of the spout cannot escape.

Abstract: A pneumatic hopper outlet, where the discharge conduit end cap is held in place with at least one large headed bolt which is pivotably mounted on the discharge conduit and which engages at least a portion of the end cap. The large headed bolt is attached to a vertically extending locking member of generally inverted J shape which is rotatably mounted on a side of the discharge conduit. When an operating handle attached to an operating shaft of an outlet valve element is in the position which corresponds to the fully closed position of the valve element, the lower surface of the locking member prevents movement of the operating handle and the valve element from moving from the closed position. If the valve element and its operating shaft are not in the fully closed position, the operating handle obstructs the path of the pivoting locking member and the large headed bolt cannot be pivoted into position to hold the end cap in closed position.
