Abstract: A non-aerosol dispenser comprises an inner cylinder defining a contents chamber. A discharge valve is disposed at one longitudinal end of the chamber. A piston is disposed in the chamber and carries a guide which includes a cutting edge. The guide is received in a manually rotatable outer cylinder which induces the piston to travel toward the discharge valve while forcing the cutting edge through the inner cylinder. The piston includes longitudinally spaced ejector and energizer members with compressed air sealed therebetween for storing and transmitting energy from the energizer member to the ejector member.

Abstract: A dispenser for viscous fluids includes a tubular cylindrical barrel member, a dispensing nozzle on one end of the barrel member and a piston element which is sealingly received in the barrel member and slidable therein in a direction toward the nozzle for dispensing a viscous fluid from the barrel member. The barrel member and the piston element are constructed so that the piston element is freely slidable in a reverse direction in the barrel member to relieve the pressure on the fluid in the barrel member after a dispensing operation has been completed and to thereby eliminate post extrusion from the dispenser. The dispenser is operative in combination with a dispenser gun which includes a drive plunger and an advancing mechanism which is operative for advancing the drive plunger in order to advance the piston element of the dispenser in the barrel member thereof.

Abstract: A seal for use between the end tube and the end plate of the outlet gate of a railroad hopper car has a generally flat body with a periphery generally coextensive with the end tube. The body is formed of an elastic material and has a shaft opening in alignment with the valve shaft of the outlet gate and a discharge opening in alignment with the discharge opening of the outlet gate end plate. There is a continuous elastic seal extending outwardly from each face of the flat body, with the seals each extending about the shaft opening and the discharge opening and being adapted to be in compressive contact with the end tube and the end plate when the outlet gate is assembled.

Abstract: A product-discharging device of a powdery/granular material processing apparatus incorporating a rotary pan. The product discharging device extends along an end wall from the vicinity of the rotary pan to the vicinity of an aperture provided at the end wall of the rotary pan. The product-discharging device guides the finished product from the interior of the rotary pan to the aperture and then automatically discharges the finished product out of the apparatus.

Abstract: The present invention includes a pistol like housing, a trigger activated ratchet controlled take up roller adapted for removably receiving the squeeze end of a collapsible tube. A flexible tube guide having opposing ends, one end being connected to the take up roller so that rotation of the roller causes the guide to be rolled around the roller. Connected to the opposing end of guide is a generally U-shaped member adapted for removably receiving the open end of a collapsible tube. Also included is a pair of springed pinch rollers adapted for squeezing extrudable material from a collapsible tube.

Abstract: The discharge rate of a solid particulate material from a storage hopper is increased beyond the rate attainable by gravity flow along through the introduction of a pressurized gas into a plenum that lies over the discharge hopper. In one embodiment, a first pipe extends vertically downward from a storage hopper, and a second pipe of larger diameter is fitted over the lower end of the first pipe so that an annular plenum is formed between the pipes. A pressurized gas is injected into this plenum and results in an increase in the discharge rate. The discharge rate can be controlled by altering the pressure of the injected gas, and the flow can be rendered intermittent by opening and closing a gate valve at the outlet of the discharge hopper.
