Abstract: Ultrasonic pest control apparatus comprising an elongated housing having opposite ends, a sound generator carried by the housing adjacent one end thereof and including at least one transducer for providing output sound waves when driven by an electrical signal, the sound waves being directed outwardly from the end of the housing and having a frequency normally inaudible to humans and intolerable by pests such as rodents and the like, and an electrical connector element at the other end of the housing adapted to be inserted manually into a standard electrical outlet receptacle commonly found in buildings and the like. The connector can be of the prong type or of the threaded type commonly found on the base of electric lamps. The transducer preferably is driven in a manner such that the generated sound waves are a composite output in the form of a random pattern of harmonies.

Abstract: Breathing apparatus comprising a mask shaped to contact a user's face and define a breathing chamber in communication with the nose of the user, a gas supply container carried by the mask having a movable valve control element, and an operator manipulated by the mouth of the user for moving the control to open the valve to introduce gas to the breathing chamber. The gas supply is controlled by the mouth of the user and inhaling from and exhaling to the chamber is through the nose of the user. The operator is carried by the body for association with the mouth of the user for moving the valve control element between open and closed positions in response to manipulation by the mouth of the user, and an exhalation valve is in the mask in communication with the breathing chamber. The apparatus can include a fluid-tight connector between the gas supply container outlet and an inlet to the breathing chamber, a manually operated member for opening and closing the valve, and a pressure gauge in the container for monitoring the pressure of the contents thereof.

Abstract: Ultrasonic pest control apparatus comprising a pair of transducers, one in the form of a ring and the other in the form of a disc positioned within the ring, carried by a housing, a pair of oscillators operatively connected to the transducers, a timer controlling the oscillators, and a reflector extending from the housing. The oscillators apply to the transducers electrical signals having frequencies different from the natural frequencies of the transducers, and the timer controls the oscillator duty cycle. The generated sound waves are a composite output in the form of a random pattern of harmonics in the ultrasonic frequency range noramlly inaudible to humans and intolerable by pests such as rodents. A system includes a pair of units in opposed alignment whereby sound waves of one unit work against sound waves of the other. A gas-tight sealing arrangement associated with transducer and housing permits safe operation in explosive atmospheres. The transducers, oscillators and timer are removable as a unit from the housing which is frusto-conical in shape permitting a plurality of units to be nested during storage and shipment.

Abstract: Breathing apparatus comprising a body in the form of a mask shaped to be worn over a portion of a user's face, a breathing passage formed in the body having an outlet in one end only in communication with one of either the nose or the mouth of the wearer and having an inlet at the other end thereof, a container holding a quantity of gas for breathing adapted for connection to the mask body with the container outlet in communication with the breathing passage and the container releasing a flow of gas to the breathing passage when connected to the body, an exhalation passage defined by the body in communication only with the other of the mouth or nose of the user and being open to the atmosphere, and a mouthpiece element associated with the passage leading to the mouth and adapted to be received between the teeth of the wearer in gripping engagement to facilitate holding the apparatus in place on the head of the user. As a result, the user does not inhale from and exhale to the same chamber of the mask, and in the event straps or other conventional holding members on the mask should break, the user can hold the mask in place using his teeth. There is provided also a valve for controlling the flow of gas from the container as it is connected to the body.
