Abstract: An insect trap of the type utilizing a container beneath an entry element. Tile container is provided with an attractant liquid and the emitted odor induces insects to enter openings in the entry element. The entry element is provided with concave baffles to enhance the dissemination of attractant odors from the container. The container is preferably a bag secured to the entry element and depends therefrom in a manner which reduces the likelihood of escape by entrapped insects.

Abstract: A sight mount for interchangeable sighting devices which provides adjustable eye relief and improved stability. The base, affixed to the receiver, is provided with parallel guideways to receive a slide support. Midway on the base is a vertically movable block which frictionally engages the slide support to lock it into position at the desired distance from the eye. A separate slide support is used for each scope for ease of interchange.

Abstract: Apparatus for purifying confined liquids and slurries by means of a spark discharge wherein the inner surface of the treatment vessel is designed to include a reflector section adjacent to a pair of electrodes and a concentrating section for intensifying the shock wave generated by the discharge between the electrodes. An external power source is coupled through a pulse forming network to the electrodes. The network is impedance matched to the impedance of the plasma arc generated between the electrodes to provide a high power pulse to the electrodes. The establishment of the plasma produces an extremely high pressure shock wave, u.v. radiation fringing on X-ray and electrohydraulic pressurization to alter the characteristics of the liquid therein.

Abstract: A boresight for determining the accuracy of a gunsight wherein a cartridge-shaped housing is dimensioned to fit within the gun chamber. A laser is contained in the housing. A switch is positioned in the end surface of the boresight housing to be contacted by the bolt face of the gun. The switch contains an indentation to receive the firing pin when the bolt face contacts the switch to activate the laser and illuminate a distant spot.

Abstract: A system for converting digital data to sine waves of differing frequency for networking computers. The sine waves are synthesized using variable encoding. The data is shifted through registers at a multiple of the data rate with the state of the stages of the register monitored to locate the zero-crossing of the sine wave. The state of the register stages is supplied to a series of multiplexers and resistors to generate the segments used to synthesize the sine waves. The data is monitored to derive a signal supplied to the multiplexers to determine the encoding pattern for each bit cell of data.

Abstract: A method of reducing soluble and insoluble impurity levels while increasing the size of water soluble salt crystals which includes an initial step of fine grinding followed by regrowth in a saturated solution of the salt subjected to agitation.

Abstract: A distance measuring system which may be used on a golf course in order for a golfer to accurately measure the distance between the present lie of his golf ball and the hole toward which he is currently advancing the golf ball. A master transceiver station is portably carried by the golfer to be disposed proximate the lie of his ball for measurement purposes, and a remote transceiver system is located in or on each hole's flag marker pole. The present system uses, as the basic measurement frequency, only the frequency of the remote carrier itself. Two separate and distinct phase measurements are made in rapid succession. The first measurement is made with the master RF carrier displaced above the remote carrier frequency by amount equal to the IF frequency, and the second measurement is made with the master carrier frequency displaced below the remote carrier frequency by the same amount.

Abstract: A method of applying a film having limited light transmitting qualities to the interior surface of a contoured car window wherein the film is first placed against the exterior surface of the window with its transfer coating facing outwardly. The film in this position is subjected to localized heating to selectively shrink the film and transfer coating to the window contour. Then, the film and coating are removed, the coating separated and the film adhered to the interior surface of the car window.

Abstract: A container for granular insecticide having a central chamber with a narrow rectangular cross sectional area. A multiplicity of rectangular slots are formed in rows and columns in the chamber to provide access to the insecticide and also enhance its attractantcy properties. The slots are dimensioned to contain the granular material while permitting access thereto by the feeding parts of the insects.

Abstract: An insect trap is disclosed which includes a double-cone structure having a receiving chamber for an attractive composition with a tapered surface and a retaining chamber for placement thereon. A conical indentation formed in the bottom of the retaining chamber provides a tapered surface which is spaced from that of the receiving chamber thus forming the first cone. The central portion of the indentation provides the second cone which is light-transmissive and has a central opening. The tapered surfaces of the chambers are opaque. An insect passageway is formed in the receiving chamber and communicates with the central opening. Thus, an insect entering the chamber through the tapered surfaces experiences light from above through the second cone and is drawn upward through the central opening into the retaining chamber where it is trapped.

Abstract: A kennel muzzle for dogs wherein a flexible headstall overlies the nose and is secured by the combination of a neck strap and a movable throat strap. The headstall includes side lobes which extend downwardly over the ends of the mouth and include receiving sockets for the clips to removably fasten a muzzle basket thereto. The rotation of the dog's head will cause an ensnared basket to break away from the headstall thereby freeing the dog.

Abstract: Apparatus for controlling the direction of traffic flow wherein a plurality of rotationally mounted levers have a free end extending upwardly from the road surface. The levers are provided with removable spikes which rotate therewith to damage tires when the levers are rotated in one direction. The free end of each lever is provided with a rotationally mounted low friction contact member which contacts the adjacent surface of the tire and moves along the surface thereof. Envelopment of the free end of the lever by the tire and the coerced rotation thereof in the wrong direction do not occur. As a result, the failure of the corresponding spike to damage a tire when the vehicle is moving in the wrong direction is thereby avoided.

Abstract: An attachment device for overhead projectors which permits blocking of the image display by changing the position of an opaque panel wherein the device is frictionally attached to the projection head. The opaque panel of heat transmitting foil is hingedly attached to a hood. The sides of the hood extend downwardly and are biased inwardly to engage the projection head.

Abstract: An attachment device for animal ear tags wherein the stud driven through the ear is provided with a molded skirt having a region of increased flexibility. Location of the region of flexibility away from the base reduces the likelihood of damage to the animal ear if the tag becomes snagged on foliage or fencing.

Abstract: System and method for preventing alteration of stored data by computer virus. In a computer system which normally automatically boots an operating system when the central processing unit is initialized, a device is provided which takes control of the central processing unit before boot-up, checks the system files for computer virus and generates an alarm signal if a virus is detected.In the preferred embodiment, the device quarantines an infected operating system to prevent alteration.
