Abstract: In the method for extinguishing fires in enclosed spaces, pre-cooled combustion products are introduced into an enclosed space until in the enclosed space there is an atmosphere that prevents combustion. An ecologically acceptable and fire-inhibiting medium that is not detrimental to health is formed by oxidizing the combustion products completely by an oxygen-containing oxidizing agent prior to cooling. An apparatus for implementing the method has a housing (1) which is divided by a transversely running partition wall (11) having at least one wall opening (15). At the at least one wall opening (15) a mixing tube (8) is mounted coaxially with respect to a discharge nozzle (2) connected to a combustion chamber (14), the end of the mixing tube remote from the partition wall (11) opening into the atmosphere. The space (7) between the mixing tube (8) and the inner wall of the housing (1) is filled with a coolant.

Abstract: A dispensing closure is provided for a squeezable container. The closure has a body with a top wall and an upwardly projecting discharge tube defining a discharge passage in communication with said container opening. A cap defines a dispensing conduit extending between an inlet aperture and a dispensing aperture, and the cap is slidable on the body top wall between open and closed positions. A hollow fitment has a first portion slidably disposed on the discharge tube and has a second portion that projects into the cap inlet aperture and that is disposed in the cap dispensing conduit to accommodate sliding movement of the cap relative to the fitment. The fitment defines an intermediate passage for communicating between the body discharge tube discharge passage and the cap dispensing conduit.

Abstract: A fluid injection device and method includes an upstream conduit, downstream conduit, a support for holding the upstream and downstream conduit with their upstream and downstream passageways aligned and maintaining a gap between the adjacent ends of the conduits, and a secondary fluid source connectable to the gap for injecting secondary fluid into the gap and downstream throat. The upstream passageway includes an acceleration nozzle for accelerating the velocity of the fluid flow so that the pressure exerted by the fluid on the walls of the upstream passageway is substantially reduced and the reduced pressure is maintained across the gap. The downstream conduit includes a downstream passageway which maintains the accelerated velocity of the primary fluid and which conducts the accelerated fluid to a deceleration nozzle. The secondary fluid source injects secondary fluid into the gap and downstream conduit at a preselected higher pressure than the fluid exiting the upstream throat.

Abstract: A radially locking spray nozzle cap, particularly adapted for quick change of spray tips on agricultural sprayer nozzles, optionally having a spray tip pressed or molded permanently in the bottom thereof. The cap has slightly resilient side walls with inwardly projecting lock lugs at the top, adapted to engage above a retainer flange on a nozzle body. Rotating the cap on the nozzle body engages the lock lugs above the retainer flange and raises the cap sealingly against the nozzle body as radial lock tabs radially distort side walls of the cap until the lock lugs pass over the lock tabs to engage adjacent recesses where the lock tabs hold the cap against counter rotation.

Abstract: A fluid projection screen is formed by projecting a substantially spatially coherent stream of fluid, such as water, and directing it against a deflection plate. The deflection plate causes the stream to be broken up into fluid droplets which form a fan shaped screen extending at an angle to the fluid stream. A projector projects an image upon the screen, and visual acuity from edge to edge of the image is achieved by imparting a bend to the deflection plate which, in turn, imparts a bend to the screen so that the distances from the center and the edges of the screen to the projector are equalized.

The PET container includes a release agent such as a layer of EVOH located outside of the inner PET layer and an air vent partway through the container wall terminating at the inner PET layer or at the adjacent release layer, so that the inner PET layer can separate from the remainder of the wall and collapse around the remaining syrup as it is withdrawn, without the need for venting the syrup chamber to atmosphere. The PET container also includes a polyethylene closure sealing the container opening and coupling means for connecting to a quick-disconnect coupling on the distal end of a syrup line. The PET container is disposable and recyclable.

Abstract: A scent dispensing system for use by hunter's or the like when a flexible bottle of scent, with a small aperture at the bottle's bottom is placed in a special holster which attaches to the hunter's foot at the ankle whereby liquid scent is forced out a drop at a time as the hunter walks to his or her hunting post. Pressure created by the action of the foot hitting the ground coupled with the pressure created by the expansion of the leg muscle and movement of the hunter's ankle as the hunter walks forces the scent to drip out a drop or two at a time. The holster has a pouch for holding the bottle made of a flexible material which is attached by a strap of elastic material. The ends of the strap are attached around the leg of the hunter by a conventional fastener. A wedge of rigid material is positioned in the pouch behind the bottle to assure that the scent will hit the ground and not the hunter or his boots.

Abstract: A binding for a snowboard has a base, side members extending upwardly and rearwardly from the sides of the base, towards the back of the base, with an arcuate member joining the rear ends of the side members. Fastening means on one side member and on one side edge of the board at the front provide for attachment of one end of each of two straps. Fastening means on the other side member and on the other side edge serve for attachment of a locking bar which in turn connects the other end of each strap to the side member and base. Attachment means are provided in the base for attachment to a snowboard. A snowboard for use in conjunction with the binding has a forward attachment position which provides for attachment of a binding inclined in either direction as desired, that is forward and to the right or forward and to the left, as desired, at about 45.degree.. A rear attachment position provides for attachment of the binding transverse of the board.

Abstract: The ski structure has a front ski and a rear ski, vibration dampers and a mechanism for converting a lateral pressure into a rotary motion, associated with one of the skis.

Thus, the rear ski follows the direction assumed by the front ski, and the ski structure can be disassembled for easy transport.

Abstract: A gas nozzle has a body threaded on a threaded conduit with an insert therebetween. This insert is not changed for another insert in order to adapt the nozzle to either natural gas or LP gas; instead, the body is tightened onto the insert and threaded conduit for LP gas and is loosened about one thread for natural gas. The insert has a first restricted orifice and a bypass passageway around this restricted orifice. The body has a second restricted orifice which is larger than that of the first restricted orifice. Thus, when the body is tightened on the conduit, a seal is made to close off the bypass passageway and the gas flow is through the first and second restricted orifices in series. When the body is loosened, the bypass passageway comes into effect and the gas flow is also through the bypass passageway to be restricted only by the second restricted orifice.

Abstract: An improved method and apparatus for producing an disbursing uniform liquid or melt droplets employing a core-fed rotating sprayer having multiple tiers of orifices.
