Abstract: A house arrest monitoring system wherein a transmitter module is attached to the subject by a strap containing a number of conductors. The module includes a microprocessor which applies a voltage to selected conductors and establishes a voltage pattern on the conductors. Any detected change in the pattern causes the generation of a tamper signal. The system is set for monitoring by an optical signal to prevent unauthorized resetting following a tamper condition.

Abstract: A modified barrel for an automatic weapon having a muzzle attachment including a gas expansion chamber to permit use of a short barrel while delivering the normal pressure to the gas drive mechanism. The attachment delivers the gas pressure via a conduit from the chamber to an exit port coupled to the gas drive mechanism of the weapon.

Abstract: An automatic insect trap having a gathering chamber removably attached to the top surface of a disposable retention chamber. The gathering chamber includes a bounded passage with an infrared beam of radiation thereacross. The insect interrupts the beam to activate a sweep panel that moves along the passageway to urge the insect to an opening in the retention chamber.

Abstract: A stackable series of interconnected boxes of equal size die cut from a single cardboard blank. When assembled, the boxes are oriented in a stack so that the lid of each box faces upwardly. Access to each succeeding box is provided by the alternate hinging of successive boxes on opposite sides of the vertical stack. Each preceding box is rotated to the side to expose the lid of the next succeeding box in the stack.

Abstract: A vehicular traffic controller is disclosed wherein the control mechanism is positioned beneath the road surface. A plurality of transversely spaced levers extend upwardly from the surface. The levers are coupled to a shaft journaled for rotation below the road surface. Shaft rotation and lever retraction is effected by an operator to withdraw the levers to a position beneath the surface. Each lever is provided with a tire disabling member. A vehicle traversing the control point with the levers extended imparts rotation to the levers and causes the disabling members to damage the vehicle tires.

Abstract: An intensity equalizing element for placement between a number of individual fluorescent tubes in a light panel and the panel image display surface. The element includes a like number of curved surfaces in axial alignment with the individual tubes to reduce variation in observed intensity due to tube spacing. Each curved surface is provided with a non-uniform opaque dot pattern thereon to reduce variation in the intensity of light at the panel display surface and enhance uniformity of light intensity throughout an overlying image display.

Abstract: A concentrate for use with an oil or water carrier for injection into a well to enhance production and a method of well treatment are disclosed. The five part concentrate contains xylene, an aliphatic hydrocarbon solvent such as kerosene, a non-ionic emulsifier, a non-ionic surfactant and an amphoteric detergent. The xylene and kerosene create a solvent hole in the materials restricting flow. The surfactant expands the holes while the detergent and emulsifier assist in dispersing the removed material to thereby stimulate production from the well. The injection of the concentrate and carrier mixture can take place during shut-in of the well or during continued production.

Abstract: A method for removing deposited material from vacuum deposition equipment is disclosed. The method utilizes a low temperature bath, between 40-50 degrees F., to strip sputter depositions, followed by an acid etch step using a low concentration of hydrofluoride acid to remove trace contamination from the surface. Following removal of deposited material, surface texturing of the components is provided.

Abstract: An ultrasonic immersion cleaning tank is constructed to serve as a pass-through between a processing environment and a clean room. The tank is sited as the entryway into a bounded clean room. Particle barriers and positive pressure are utilized to reduce entry of contaminants into the clean room. The components after cleaning are withdrawn from the tank directly into the clean room environment thereby greatly reducing surface contamination thereof.

Abstract: A pellet dispenser wherein pellets are loaded into a cylindrical cap having a centrally-located tube. The tube contains a guide and a flange end. The dispenser includes a base having an inclined skirt bounded by an external flange with a post to be inserted into the tube. The post is provided with a circumferential shoulder and a guideway. Insertion of the post into the tube orients the cap and base and permits relative rotation. The assembled dispenser is inverted for use.

Abstract: A preform for use in constructing an archway wherein opposing sheet metal cheek are spaced apart by a curved throat to permit the cheeks to reside between the adjacent wall support and the overlying wallboard or drywall. The preform is affixed directly to the support members. Drywall is fastened to the preform by screws with the seams between adjacent drywall sections being covered in the conventional manner. The attachment of the preform directly to the wall supports essentially eliminates the likelihood of joint separation or fastener movement after installation.

Abstract: A hand held decoy and hunter shield wherein an oversize colored silhouette of a game fowl is provided with a central viewing opening covered with a screen having the coloration of the adjacent parts of the silhouette. A handle is connected to the silhouette to permit the hunter to view the surrounding area through the shield while minimizing his exposure to game fowl in the field of view.

Abstract: A closed filtration system for transporting a liquid from a first container through a filter to a second container by the injection of gas under pressure into the first container. The container's filter and fluid conduit are attached to a common housing. The housing is provided with gas and liquid channels for each container. Ingress and egress tubes extend from the channels into the containers to permit the transfer of liquid from the first container to the second container.

Abstract: An electronic scale for use in fishing competitions employing a load cell for accurate measurement and including memory for storing and coding measured fish weights. The scale automatically sorts and scrolls through the stored information to display the code and weight of the lightest fish to permit immediate culling of the catch by the user.

Abstract: A circuit for reducing the effects of unpredictable changes in power supply and variations in loading on sensitive equipment, e.g. CT scanning system, to reduce inaccurate readings and protect equipment. The circuit utilizes a network of variable reactances controlled either by manual switches or by a microprocessor receiving inputs from a plurality of monitoring locations within the network.

Abstract: A novel attachment system provides rapid alignment and attachment of adjacent modular panels which eliminates interpanel support members and permits individual panel reversal. The system utilizes pairs of substrates affixed to each panel edge. Each substrate has a plurality of tapered pins and sockets for alignment. Portions of the panel edges are provided with releasable VELCRO-type fasteners for attachment. Disassembly is accomplished by the application of tension to adjacent panels accompanied by a bending force at the junction therebetween.

Abstract: Apparatus for generating a pulsed plasma in a liquid medium wherein a pulse forming network is provided to supply a high energy pulse to spaced electrodes for creating a spark channel and initiating the plasma. The pulse forming network is impedance matched to the average impedance of the plasma channel established between the electrodes. The network generates a 5 to 20 microsecond pulse in the gigawatt power range to effect energy transfer to the plasma before significant expansion can occur.

Abstract: A dispenser for stored rodenticide pellets wherein the pellets are contained within a cylindrical cap which is maintained in contact with a base. The base includes an inclined skirt bounded by an external flange. The cap is raised on a central post to enable the pellets to move down the inclined base and rest adjacent the flange. The pellets are then available to rodents while being retained on the dispenser by the flange. The cap can be lowered to close the dispenser to deny access to remaining stored pellets.
