Abstract: A fire sprinkler including a valve retained by a tubular body that defines an inlet for connection to a supply of pressurized fire extinguishing fluid and an outlet for placement in a fire protected zone. The valve is movable from a closed position to an open position by a primary force produced by the pressurized fluid at the inlet. In the closed position, the valve provides a fluid tight seal between the inlet and the outlet and in the open position allows fluid flow therebetween. Retained by the valve and movable therewith is a locking mechanism reciprocably movable between an engaged position and a disengaged position. The locking mechanism is adapted in the engaged position to transfer between the valve and the tubular body a substantial first component of the primary force and to thereby prevent relative movement therebetween and is adapted in the disengaged position to substantially eliminate the first component of force and thereby allow relative movement therebetween.
Abstract: An electronic reset circuit is provided for a fluid dispenser of the type including a fluid pump and a meter, wherein upon deactivation of the fluid pump, the meter must be reset in order to reactivate the pump and a resetting device normally actuatable for accomplishing meter resetting.

Abstract: This invention provides an improved vibratory storage pile discharger unit for promoting the downward flow of material from a storage pile of a flowable material, such as coal, limestone, woodchips, sulphur and the like, through an opening in a generally horizontal surface on which the pile is supported and into another area located beneath that pile-supporting surface.
Abstract: A device for spraying a noxious powder includes a housing for a CO.sub.2 cartridge, and a moveable barrel which carries a firing pin by which the cartridge can be punctured to explosively release the gas. The barrel has a nozzle at its outer end, and contains the noxious powder in a chamber defined between the barrel and the firing pin. When the barrel is released from an outwardly extended position it is thrust by a spring against the rupturable end of the cartridge, thereby releasing the gas which in turn propels the active agent through the nozzle and toward the assailant at whom it is aimed. Generally, a powdered tear gas will be employed in the device.

Withdrawal of the carrier member leaves the first opening in the bag wall opposite the pouring spout available as a breathing spout.
Abstract: A dispenser device is described having a metering chamber provided with inlet and outlet ports. Independently mounted, angularly disposed valves are associated with the ports. An activator comprising a cam wheel driven by an electric motor operates the valves in predetermined sequence through valve control arms respectively associated with each of the valves. The valve control arms are pivotally mounted and co-operate with an extension of the valve stem extending externally of the metering chamber. The electric motor is actuated by a button operating through a lever so as to close a switch. The cam wheel includes a switch cam track which holds the switch closed for a full cycle of the dispenser. Also a deactivating cam track is arranged to displace the lever so that manipulation of the button cannot effect the dispenser operation once the cycle has been initiated.
Abstract: Vending machine for flat articles having a housing at a portion of which there is an article delivery slot. Within the housing there is an ejection plate which can be moved by an actuating handle and by which one article at a time can be carried through the delivery slot from the stack of articles which is standing on an inclined supporting plate within the housing.
Abstract: A dispenser for pasty substances and/or liquids has two coaxially arranged metering pistons 11,24 which supply charges of material from two coaxially arranged pump chambers 14,23 through ejection channels 19,26 into an ejection chamber 20. The material can emerge from ejection chamber 20 through an outlet 4. This outlet 4 is controlled by means of plug 21 biassed in closing direction. When the metering pistons 11,24 are on their suction strokes material passes from the supply tanks 17,27 which are likewise arranged coaxially one inside the other. Such a configuration yields a dispenser which consists in essence of two separate dispensers, one inside the other. The two streams of material combine directly ahead of the outlet 4.
Abstract: A snuffer is provided for putting out fires in oil tanks or oil wells which consists of a framework for maintaining an asbestos or the like covering, forming a cap which can be lowered over the fire. A fire retardant fluid may be injected within the snuffer.
Abstract: An impeller is connected to a liquid-powered motor to be driven thereby. The impeller is of a type capable of moving a large volume of air of the order of as much as several thousand cubic meters per minute, which is ten or more times the volume of liquid used to power the motor. Some or all of the liquid applied to the motor to be transformed into mechanical energy is carried by a conduit to a point where it can suitably enter the air stream provided by the impeller. The conduit can carry the liquid to a point between the motor and the impeller so as to be picked up along with air and included in the stream forcibly projected from the impeller. Alternatively, the conduit can be routed around the impeller to discharge the liquid into the already formed air stream.
Abstract: A liquid storage and measurement system particularly applicable to the volumetric measurement of siquid hydrocarbon fuel and to the dispensing of the fuel via a fuel dispensing unit, includes a liquid measurement/storage vessel of known dimensions arranged to be partially filled with liquid, e.g.

The rigid conduit terminates in a nozzle at an upper end and includes a swivel connector proximate the housing to permit rotation of the nozzle to permit water spray to the left or right of the vehicle. When pivoted to a horizontal position, the base of the tower is exposed so that lights mounted on the base shine rearwardly of the truck.
Abstract: The invention features improved fluid deflection techniques for a pendent-type fire-protection sprinkler head. A first deflecting surface facing generally upward is positioned in the path of fluid emerging from the body of the sprinkler and includes a portion spaced to circumferentially redistribute the fluid to improve uniformity of distribution and deflect at least some of the fluid generally outward. A second deflecting surface positioned radially outward and away from the first deflecting surface receives and controls the distribution of a portion of the outwardly moving water from the first surface; the path of emerging fluid from the sprinkler head body to the first deflector surface extends through an interior opening in the second deflector surface; and the second surface is separated from the first surface by a circumferentially unobstructed region so that the circumferential distribution of the fluid leaving the first surface is not divided as it moves between the first and second surfaces.
