Abstract: A pet toy may include a hollow compressible body having a mouth about an opening leading to an interior of the body and a tab having a head and a neck extending from the head. The neck extends through the opening while the head is larger than the opening. The neck is slidable through the opening to move the head between a silent position and a squeaking position. In the silent position, the head is spaced from the mouth to allow air flow from the interior of the body through the opening between the neck and the body without producing audible sound. In the squeaking position, the head is sufficiently close to the mouth such that airflow from the interior of the body through the opening between the neck and the body and between the mouth and the head produces an audible squeaking sound.

The walls are a bottom wall, a fore end wall extending upwardly from the bottom wall and formed with a lateral, inwardly extending living hinge, an aft end wall extending upwardly from the bottom wall, a pair of opposite, outwardly bowed side walls extending upwardly from the bottom wall and joined to the end walls and a top wall inclined at a wedge angle to the bottom wall and joining the side walls and the end walls. A whistle extends through a wall of the air container.

Abstract: An animal behavioral control apparatus includes a cartridge, a housing, a head, and an extension assembly. The cartridge contains pressurized gas. The housing surrounds a part or more of the cartridge. The head is connected to the housing and includes an actuator and a valve. The valve engages the cartridge when the actuator is actuated in order to release gas out of the cartridge. The extension assembly is connected to the head to receive gas from the head. Upon actuation of the head, gas flows through the extension assembly and the animal behavioral control apparatus ejects a blast of gas which can be directed at an animal.

Abstract: An animal behavioral control apparatus includes a cartridge, a housing, a head, and a horn. The cartridge contains pressurized gas. The housing surrounds at least a part of the cartridge. The head is connected to the housing and includes an actuator and a valve. The valve engages the cartridge when the actuator is actuated in order to release gas out of the cartridge. The horn is removably connected to the head. When the horn is not connected to the head, the animal behavioral control apparatus ejects a blast of gas when the actuator is actuated. And when the horn is connected to the head, the animal behavioral control apparatus emits a sound when the actuator is actuated.

Abstract: An electropneumatic acoustic horn is disclosed, comprising an electric compressor unit for generating compressed air and a sound wave generator comprising at least an acoustic chamber associated to at least a volute wound acoustic duct adapted to propagate the produced sound to the outside. Air channelling means put the compressor unit in communication with each acoustic chamber. The compressor unit and the sound wave generator are mechanically connected in a removable way by fitting slidingly a collar.

Abstract: This invention relates to a pneumatic valve device, such as a pneumatic horn and a pneumatic sprayer, which is operable by pressurized gas from a storage vessel. It comprises a valve pneumatically connectable to the storage vessel to admit and release pressurized gas into and from the storage vessel; a connecting chamber for pneumatically connecting the valve to the pneumatically operable device to conduct pressurized gas released through the valve to the pneumatically operable device; and a manually operable control operable to release pressurized gas from the valve into the connecting chamber.

Abstract: The inventive audible warning device includes, in a preferred embodiment, a refillable pressurized air tank having a service port, a cover for covering the service port, an air pump integrated with the tank for filling the tank within pressurized air, an activator for regulating air flow, a hose connecting the tank to the activator, and a horn connected to the activator. The cover also includes a relief valve for depressurizing the tank. In addition, the cover includes locking elements for locking the cover, which can include in turn a rotatable handle that triggers the relief valve when the locking elements are unlocked. A method for producing sound is also disclosed herein.

Abstract: This present invention relates to apparatus for use in hunting wild game animals and waterfowl, and more particularly to a weapon mounted wild animal game caller. This weapon mounted wild animal game caller finds particular application in attracting deer. It may be conveniently mounted and attached to an archery bow or to a hunting firearm. The game caller emits a grunting sound which is know to attract game animals, such as deer. The use of the grunter is very desirable for short range hunting making it the choice for many bow hunters. The activation of sound is accomplished by a novel air bladder that is filled with a resilient filamentous polyester type fiber. When mounted to an archers bow, it is easily operated with the hand even with a fully drawn bow.

Abstract: A handheld device used by skaters and the like for warning pedestrian traffic comprises an air bladder attached to a strap that is secured to the palm of the hand in such a way that when the user simply squeezes the bladder firmly, a loud honking sound is emitted. The sound is created by air passing through a disk containing a small vibrating reed that is housed on the posterior side of the air bladder. Additionally, the handheld warning device may incorporate a palm protection pad to minimize injury to the hand in the event that the skater falls down.

Abstract: A warning apparatus comprising a plurality of warning mat units interconnected and arranged side by side in a such manner as to surround a dangerous area, in which the warning mat units each comprise a base plate, a flexible cover sheet secured to an upper side of the base plate, the cover sheet being provided with a plurality of upwardly expanded shells having an inside hollow room and air circulation apertures, and a warning sound generator accommodated in the inside room of the shell, in which the warning sound generator comprises a closed elastic tube fastened on the base plate and a whistle affixed to a wall aperture of the closed elastic tube so as to give forth sound by the effect of air flow passing between an inside and an outside of the closed elastic tube.

Abstract: An audible push-up detector produces a sound when the device is compressed between the chest of a user and the underlying floor or surface, thus alerting an instructor or supervisor, as well as the user of the device, that the exercise has been performed properly. The device comprises a hollow, air filled flexible, pliable, resilient container having a reed valve or the like installed in one side. When the device is compressed, as between the chest and the underlying surface when a person is performing push-ups, air within the device pneumatically actuates the reed valve to produce a sound. Thus, the device is most useful in group exercise or physical training sessions, where a single supervisor or at most a relatively few supervisory personnel must monitor a large number of persons performing push-up exercises. The device includes a spacer disposed therebeneath, to position the pneumatic device at the proper height.

Abstract: Disclosed is a stationery case for keeping writing materials, which comprises an ornament mounted on a compression spring which is fastened in the interior of the casing. The ornament has a magnet fastened therein and is pressed and released so that clips which are received inside a curved recess in the casing can be taken out of the casing and placed on a recessed surface portion on a cover at the top of the casing for ready use. A plurality of compartments are made inside the casing in the portion opposite to the curved recess for keeping a variety of writing materials. A whistle is fastened inside the casing and is controlled to make a sharp, clear sound during a downward stroke of the ornament.

Abstract: A device for attaching to the underside of an internal combustion engine accelerator which is compressed during depressing of the accelerator. A rate of accelerator depression faster than that efficiently necessary causes the device to emit an audible signal indicating excessively rapid accelerator movement such as causes the wasting of gasoline. The device comprises an expansible chamber motor in the form of a bellows having a reed type sound producing element actuated by air forced from the bellows during accelerator depression.
