Abstract: Method and apparatus for supplying a preset quantity of a liquid, using a tank containing the liquid, a check valve distributor, and a hose connecting the tank to the check valve distributor, and having a pumping unit, a solenoid valve, and a pulsed flow meter interposed between the tank and the check valve distributor, including determining a volume difference between a first quantity delivered by the apparatus and a first quantity detected by pulsed flow meter, as the liquid is pumped at constant flow rate, low pressure and under laminar flow, during a first delivery of the liquid; starting a subsequent delivery of the preset quantity of the liquid, by opening the solenoid valve; and stopping the subsequent delivery of the preset quantity of the liquid when a difference between the number of pulses generated by the pulsed flow meter corresponding with the preset quantity, and the number of pulses output by the pulsed flow meter reaches a number of pulses corresponding to the volume difference; and during a

Abstract: A personal protection device having a size, configuration and appearance simulating a telephone pager or beeper but having the capability of emitting an incapacitating chemical spray in the event of an attack on the person. The device contains multiple canisters of compressed gas containing the chemical and a movable manifold unit which can be pressed to release a chemical stream from each of the canisters and at the same time integrate the streams to provide a single, forceful spray of debilitating chemical. The device in one embodiment also incorporates a high decibel alarm system to be used in conjunction with the chemical spray.

Abstract: Shaker for the condiments such as salt and pepper having a structure which provides for the salt or pepper to be discharged by shaking up and down but without reversing the shaker from its storage position, the condiment remaining is effectively isolated from the atmosphere.

Abstract: A toner cartridge is extractably set in a storing recess of an image forming apparatus main body, and toner is supplemented to a specified part of the image forming apparatus main body. While the toner cartridge is brand-new, an inner seal member peelably adhered to the lower surface of the toner cartridge main body seals the toner dropping opening at the lower surface. After setting the toner cartridge in the storing recess, by peeling off and taking up the inner seal member by the take-up shaft, the toner dropping opening is unsealed. An outer seal member provided slidably along the lower surface of the toner cartridge main body opens or closes the toner dropping opening beneath the inner seal member. When the toner cartridge is drawn out from the storing recess, an outer seal member operating member becomes engaged with an engaging part of the image forming apparatus main body, thereby automatically closing the outer seal member.

Abstract: A water cannon is arranged for both pulsed and continuous flow. A turret is provided for supporting and aiming a water cannon nozzle. Advantageously, the water cannon includes a pump which accelerates water through a closed loop until operation of a first valve directs the water to the turret. In the pulsed mode, a second valve keeps the nozzle normally closed, and the flow causes pressure in an air chamber to increase above a predetermined level, thereby opening the second valve and allowing the water to exit the nozzle. This flow reduces the pressure in the air chamber below the predetermined level. As a result, the second valve is actuated to stop the flow. In the continuous flow mode, the second valve is maintained open to allow the flow directed from the closed loop to exit the nozzle in a continuous flow.

Abstract: A rocker bucket gold recovery system comprising a container having a plurality holes disposed thereon for drainage; a rocker coupled to the container for rocking the container; a plurality of classifying screens; and separating mechanism for separating the classifying screens when disposed within the container, thus creating a configuration adapted for effecting a separation of materials poured into the container into portions composed of essentially equivalent sized particles.

Abstract: A dispenser cap for fluid substances, including relatively movable members defining a dispensing hole and an appendix for closing the hole. When the cap is in a closed state, the cap surface in proximity with the dispensing hole is substantially smooth and uniform. When the cap is in a dispensing state, a tubular element in which the hole is provided projects from the surface.

Abstract: A system for dispensing liquid soap including a closed wall structure defining a container with a partition separating the container into a separate lower liquid soap reservoir and a separate upper refill compartment. Dispensing mechanism is carried by the container for dispensing liquid soap from the reservoir. The partition has a refill aperture therethrough providing communication for soap flow between said reservoir and the refill compartment and dimensioned to permit the free flow of liquid soap therethrough. A refill cartridge of liquid soap has an outlet, removably enclosed within the refill compartment in a refill configuration with the outlet disposed for cooperation with the refill aperture to permit the free flow of liquid soap from the refill cartridge to the reservoir thereby to refill the reservoir as liquid soap is dispensed therefrom.

Abstract: A squeeze bottle for dispensing viscous liquids of the type having a conventional opening and associated flip lid at the top thereof is provided with a second opening and associated flip lid positioned adjacent the bottom of the squeeze bottle so that the contents remaining when the bottle is nearly empty may be easily dispensed therefrom. Alternatively, the conventional top opening and flip lid may be eliminated and a single opening provided adjacent the bottom of the squeeze bottle. In another embodiment, a squeeze bottle is symmetrically configured to have flip lids of sufficient surface area at each end thereof to permit storage of the squeeze bottle on either end so that the contents may be easily dispensed from the flip lid on which the squeeze bottle rests during storage.

Abstract: The dispenser comprises a flexible bag (2) containing a liquid or paste (6) and housed in a container (5) having a rigid wall (53) with an elastic bellows (51), a handle (43) and a closure system (3) which opens or closes when the product (6) is not at an adequate pressure. By pressing on the handle (43), the air trapped between the container (5) and the flexible bag (2) exerts adequate pressure on the product (6). The dispenser also comprises a cap (42). The dispenser neck (41) is connected by film hinges (48, 49) to both the handle (43) and the cap (42).

Abstract: Assembly of a pressurizable beverage keg (8) and a reservoir (1) of pressurization gas containing CO.sub.2 and comprising an expansion valve (5). The reservoir (1) is a toric portion (2) disposed concentrically at one end of the keg (8). The expansion valve (5) is mounted on one of the ends (3) of the torus. The keg (8) has at one end a handling skirt (11) defining an internal space, and the reservoir (1) is entirely disposed in the internal space of the skirt (11). The expansion valve (5) is coaxial to its end (3) of the torus (2) and has a passage (6) for emptying and filling the reservoir (1), opening through the peripheral wall of the reservoir (1) adjacent the same end (3) of the torus.
