A piston is slidably disposed in the chamber and is spring biased to a fired position, wherein the piston is adjacent the opening. A reservoir is also mounted on the housing. A cocking member is movably mounted on the housing, and the cocking member can be manipulated to move the piston to a load position, wherein the piston is distanced from the opening of the cylinder and water from the reservoir can enter the chamber. Also, a firing mechanism is provided for releasing the piston to permit it to rapidly return to the fired position and thereby emit water from the chamber through the opening in a burst pattern, and to give an audible and tactile indication of water emission.

Abstract: A twist-to-open dispensing closure has a cap which threads directly onto the container neck. A bead at the bottom of the cap skirt snaps over a flange on the container neck for primary retention of the cap on the container neck. An upwardly projecting lug on the cap bead cooperates with a pair of axially extending walls on the container flange to give the user, while unthreading the cap, a sense of approaching the open, dispensing position of the closure and the cap locks in this dispensing position against further rotation, preventing accidental removal of the cap by snapping the cap bead over the container neck flange.

Abstract: An apparatus and method for serving beer at proper CO.sub.2 content and proper temperature for best taste, comprises a draft tower for distributing beer at the proper gas content and at the proper temperature. A plurality of beer barrels connected in series are in turn connected to the draft tower by a pipeline. A CO.sub.2 gas cylinder is connected to the barrels for supplying gas at an elevated pressure sufficient to move the beer from the barrels along the pipeline to the tower. A heater is provided for heating the barrel to an elevated temperature above the proper temperature for taste, so that the gas content in the barrel does not rise above the proper gas content under the influence of possibly elevated pressure needed to convey the beer. Near or at the draft tower, the beer is recooled to the proper temperature and thus served at a proper temperature and with the proper gas content.

Abstract: A rotatable cap and modified container neck. Depending from a top panel of the cap is an annular exterior wall and a smaller concentrically positioned interior wall with a space between the two walls sized to receive an upper and thinned portion of the container neck with a tight fit providing a fluid seal. The interior wall of the cap contains a dispensing notch which is aligned straight across with a dispensing opening through the exterior wall. With rotation, the cap raises and lowers on threads relative to the container. When the cap is lowered, the container neck blocks the dispensing canal between the notch in the interior wall and the dispensing opening in the exterior wall of the cap. The top rim of the container neck abuts the interior cap ceiling between the two walls to form a seal. When the cap is raised, the container neck is in part below the notch in the interior wall and the dispensing opening, and thus the dispensing canal is open.

Two different consistencies of plastic material are used to structure the outer cap to provide a relatively rigid outer cap structure having a relatively soft interior surface for improved sealing against the neck of the container. A first stop block is located on the lower exterior of the container neck, and a second stop block aligned for abutment with the first block is located on the lower interior of the cap to limit rotation of the outer cap.

Abstract: A self-closing squeeze container. A resilient curved plastic rib of a degree of flexibility which is used to tighten the mouth of the container with a suitable resilient return force of the rib. The rib is fastened to the ends of the mouth to keep the mouth closed under its own tension which can be overcome when the container is squeezed by hand strongly enough to flex the rib but not enough to stretch the mouth. This is done by using the force needed to retain the rib's resistance to being straightened out. Examples are given in collapsible and stand-up flexible containers including flip-top types, smooth-opening types, and audible, including audible-"snap"-action, varieties using the idea.

Abstract: A toner cartridge is modified by the addition of a low toner sensing mechanism internal to the cartridge. An arm is pivotably mounted within the cartridge; the suspended end of the arm having a magnet secured thereto. When the cartridge is filled to a relatively high level with toner and rotated, the suspended arm is at least partially submerged in the toner bed and is subjected to a viscous drag force which moves the arm from the vertical position and prevents the arm from returning to the vertical or plumb orientation until a sufficiently low toner level occurs. At this point the arm is sufficiently free from the viscous drag effects of the rotating toner bed and attains a plumb position which brings it into alignment with a switching circuit which is closed by action of the proximate magnet. The switching circuitry generates signals which are used to produce a visible or audible signal to the operator, and/or which cause machine shut down to occur.

Abstract: A cheese dispenser is provided with a compartment having closed ends, top, bottom, and sidewalls and open front end.

The disc also operates through a gear reduction unit to drive a pusher simultaneously with the opening of the flexible cover or door. Thus by rotating the disc, the door is open simultaneously with advancement of the cheese out of the open end. A slicer mechanism is provided on the open end to slice desired thicknesses of the cheese.

Abstract: A metering and dispensing cap for use with material containers such as spice jars is disclosed. The cap has a housing that extends horizontally across the mouth of the jar and provides a rectangular outer aperture spaced apart from an aperture that communicates with the interior of the jar. A metering rotor having a plurality of compartments of equal volume spaced around its circumference is provided in the housing between the two apertures. Upon turning the rotor, the compartments are sequentially filled by exposure to the contents of an inverted jar and emptied when aligned with the external aperture. The compartments are defined by axially extending, spaced-apart blades on the rotor. Wiping action to obtain precise metering is obtained by movement of the blades past a curved surface of the housing in slight spaced-apart relation. Amounts of dispensed material are obtainable in multiples of the amount contained in one comparment. A detent mechanism enables control and sensing of the amount dispensed.

Abstract: A passive air, gas aerosol or pressurized fluid activated personal self-protection screech alarm device that is armed prior to the person utilizing it entering into a potentially dangerous area or situation. The primary and radically different feature of this device from those currently patented and/or on the market is that no action is demanded of the person carrying it in the event of an attack other than the natural inclination to release ones grip. Releasing ones grip on the aerosol can and lever and dropping the device then activates an irrevocable screech alarm. This device plays to the psychological implications of attack in that if active, overt action is taken by the person who is the subject of a rape, for example, the attacker oftentimes becomes more violent. With this device, the natural inclination to show fright and drop whatever one is carrying serves to activate the alarm.

Abstract: A non-pressurized fluid transfer system for stock rotation of liquids packaged in large non-pressurized containers such as 55 gallon drums is described. Two drums or sets of drums are used and the system automatically changes over from a first drum to a second drum when the first drum no longer contains liquid. Automatic change-over between the first drum and second drum is effected in response to a signal created by a float switch in the drum's fluid line. This float switch detects the absence of liquid in the first drum and the system automatically switches to the second drum in order to maintain continuity of the dispensing process. When the first drum is replaced with a new drum, the operator pushes a purge button and the fluid line connected to that drum is purged of any air. Thus, the dispensing of fluid may be continuously maintained without any interruption from changing drums, and without introducing air into the dispensing line.
