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: A novel fluid coupling, a novel tool for removing a coupling seal from the novel fluid coupling, and the method of utilizing the coupling seal removal tool. The coupling 10 includes a check valve 58 which has a skirt portion 64 normally disposed within a coupling seal when either a male coupling 12 is connected to it, or when the male coupling has been removed. The female coupling is so designed that the skirt of the check valve can be entirely shifted outside of the coupling seal 62 when the novel seal removal tool 68 is inserted into the open end of the coupling. The tool is provided with a knife edge (between surfaces 82 and 84) which can engage the inner annular surface of the seat 62 and cause the seal to be removed when the tool is removed from the open end of the female coupling.

Abstract: A thief-trapping apparatus for a room having a closure permitting room ingress and egress and an object therein to be safeguarded utilizes a locking mechanism for the room closure and a cord having a frangible link. The locking mechanism includes a bolt and a bolt receptacle which are operatively mountable on the closure and the wall of the room adjacent the closure. When operatively mounted on the room wall and closure, the bolt is movable between a first position at which the bolt cooperates with the bolt receptacle to lock the closure in a closed condition and a second position at which the closure is unlocked. The locking mechanism further includes a spring for biasing the bolt from its second position to its first position, and the cord is fastened at one end to the bolt so that when the cord is pulled from its other end, the bolt moves to its second position.

Abstract: An apparatus and associated method for relieving the pressure within a high pressure tank having an opening plugged by a broken safety valve of a special type utilizes a mechanism acting between the annular flange of the tank normally provided for the securement of a valve protector cap and the valve to permit pressurized contents confined within the tank to escape through the valve. The special valve includes a flow passage in axial alignment with the tank opening in which the valve portion is received and defines a ball chamber in which a spherical ball is seated. The apparatus of the invention includes a stem which is movable through the valve portion flow passage for engagement with the spherical ball to thereby unseat the ball and open the valve flow passage. By unseating the ball, contents of the tank pass out of the valve flow passage and are directed either into the atmosphere or another vessel for reclaiming purposes.

Abstract: An apparatus for discharging fish feed, including a feed portioning device (1-3) connected to a probe device (5), which is at least partially immersed in water and excitable by fish for activating the portioning device such as to discharge a quantity of feed to the fish. The probe device contains an element (8) sensitive to sound and/or pressure waves and which reacts for pushes against the probe device achieved by the fish, and accordingly sends signals to an electrical device (4) for activating the portioning device (1-3).

Abstract: A nozzle assembly (44) for a filling machine, the nozzle assembly controlling foaming and dripping of the product during and after the filling operation. The nozzle assembly includes a nozzle body (46), a fixed filling tube (48), a movable tube assembly (50), and movable cam structure (52). The movable tube assembly is provided with a sealing foot (80) through which a bore extends, the body being interconnectable with a vacuum line (66) after the completion of the filling of a container (16) to prevent dripping on the container. The movement of the movable tube assembly (50) is controlled by gear structure (100) associated with a valve (38) which controls the discharge of material through the nozzle assembly, in such a manner that the nozzle assembly will be closed when the valve is closed.

Disposed within the valve body (14) are a movable diaphragm assembly (22) and an exhaust port plate (24) supported by and movable toward and away from the diaphragm assembly.

Abstract: A speed and direction control apparatus for a skid steer vehicle of the type having right and left driven wheels which are caused to be operated by variable displacement pumps. The control apparatus is similar to that found in normal highway vehicles in that a steering wheel is provided for controlling the turning of the vehicle and a foot pedal is provided for controlling the speed of the vehicle. One end of each of a pair of push-pull control cable assemblies is used to move the control arms of the variable displacement pumps and the other end of the pair of control cables are in turn secured to a rotatable element which is in turn supported for rotation on a portion of a rotatable steering column. The rotatable element can be rotated by the steering wheel to cause one control arm to be displaced with respect to the other control arm to effect turning of the vehicle.

Abstract: An anode assembly for a lithium-halogen cell including halogen-containing cathode material, i.e. depolarizer, such as an iodine-organic complex wherein the anode comprises an electrical conductor sandwiched between a pair of lithium plates defining substantially oppositely directed lithium surfaces terminating in a peripheral lithium edge and characterized by a major portion of the length of the peripheral edge being exposed to the cathode material. This greatly increases the available internal volume of the cell for cathode material which, in turn, increases the theoretical ampere-hour rating of the cell. At least one and preferably both oppositely directed lithium surfaces have formations such as ribs or the equivalent which increases the surface area thereof, and the formations terminate a short distance from the edge to form a marginal type, peripheral border and highly effective seal therearound.

Abstract: A pocket reducing insert for the pocket of an A.N.S.I. toolholder designed to nestingly accept a first cutting insert of a predetermined size and shape is in the form of a notched body of such size and shape to be nestingly received within the toolholder pocket, and the notch of the body is of such size and shape to nestingly accept a second cutting insert of smaller size or smaller size and different shape than the one which the A.N.S.I. toolholder is designed to accept. When the reducing insert is placed within the toolholder pocket, the toolholder pocket can nestingly accept the second cutting insert. An associated clamping assembly when used in combination with the reducing insert, for holding the second cutting insert within the toolholder pocket is particularly well-suited for use during machining operations during which machining pressure tends to pull the second cutting insert out of the pocket.

Abstract: Sewing operations are automated, at least partially, using a controllable sewing machine. In an intial recording phase for the sewing operation to be effected, there are put into memory the instantaneous values of three sensed parameters, i.e. the elapsed time of sewing, the position of a sewing speed control element and the length of the sewing, at each time the position of the speed control element changes under the action of the operator. Then, in a reproduction phase, the time is detected in continuous fashion, as is the distance sewn, and the position of the speed control element is changed at each moment for which the time detected is equal to a time recorded, or for which the length sewn is equal to the length recorded.
