Abstract: An encapsulating system for abating and mitigating contamination from lead-based dust, particles and/or chips in a construction repair, renovation or removal operation and thereby minimizing exposure to lead-based hazardous materials is provided. The apparatus utilizes a framing mechanism supporting an encapsulator container or workbag adapted to surround and seal off a work-area encompassing a contaminated work-piece. The framing mechanism is typically adjustable poles or an adjustable frame apparatus having a plurality of height adjustable vertical legs. The flexible plastic encapsulating container is positioned and supported by the adjustable poles or frame. The container has at least one open-end for surrounding the contaminated work-piece, and the open-end of the container is adhered to the work-area and substantially surrounds and seals off the contaminated work-piece from the interior portions of the work site.

Abstract: A system and method for the disposal of refuse from refuse bins in a public dining area of a restaurant to a dumpster located outside the restaurant. The system includes a refuse container, the use of which is restricted to transferring refuse-filled bags from refuse bins to a staging area located toward a rear of the restaurant. The volume of the refuse-filled bag is reduced by a compaction device and placed on a shuttle, which is used to transfer the refuse-filled ages to the dumpster.

Abstract: An access control system prevents a mobile container from being compromised/opened during transit, through the use of a programmable electronic lock, which can be unlocked only by means of an enabled electronic key that has been programmed with geographical location data representative of the destination site of the container. When the mobile container arrives at its destination, the key is coupled with a comparator, which compares the geographic location information in the key with real time geographic location information from a geographic location detection unit associated with the mobile container. In response to a match, the comparator enables the key for a prescribed period of time. The key may then be inserted into the programmable electronic lock, which reads the key to determine whether it has been enabled. If the key is enabled, the lock can be unlocked, to provide access to the container.

Abstract: The present invention is a manually operated trash compactor with a refuse container mounted on a mobile platform. The container has a first section fixed to the platform and a second section pivotally attached to the first section. A latch is mounted to the container to hold the container closed during compaction. A compaction plate is mounted to a rack gear and pinion gear assembly. The assembly is rotatable between a starting position, with the compaction plate disposed over the refuse container, and a position lateral to the container. A drive wheel is connected to the pinion gear to rotate the pinion gear to selectively adjust the rack gear and compaction plate into the container to compress refuse in the container lined with a trash bag. A compression spring is mounted on the rack gear to facilitate automated return of the compaction plate to its starting position. A tension adjuster is in contact with the rack gear to control the rate of return of the rack gear.

Abstract: A moisture sensor to sense rain on a windshield. The sensor members on the outboard surface of the windshield are uncoated and directly exposed to any moisture accumulation on the sensor. Leads connect the sensor to an electrical signal generator and receiver and are insulated from each other to prevent direct electrical interconnection therebetween and subsequent shorting of the sensor circuitry. When moisture is on the sensor, the nature of a monitorable electrical signal passing through the sensor changes and is detected. In response to the altered signal, the windshield wipers are actuated.

Abstract: A method and apparatus are disclosed for producing a film on a substrate surface from a cloud of dust-sized particles of a coating reactant.

Abstract: A self-contained pre-intrusion detection and alarm system for doors and other closures, the system including an rf oscillator circuit incorporating a tank circuit which includes an antenna. The system also includes a detection and processing circuit effective to detect and amplify a change in the voltage in the rf oscillator circuit caused by a change in the antenna to ground capacitance; an audio oscillator circuit; time delay circuitry connected between the detecting and processing circuit and the audio oscillator circuit and controlling the energization of the audio oscillator circuit; and an alarm electrically connected to and controlled by the audio oscillator circuit for alerting occupants of potential danger of intrusion and also deterring potential intruders from continuing their activities toward intrusion.

Abstract: A method for making dialkyltin difluorides by reacting the corresponding dialkyltin diacetate with hydrogen fluoride is disclosed.

Abstract: Electroconductive tin oxide coatings are deposited by an airless method of spraying a liquid composition of a thermally decomposable tin compound onto a hot glass surface in order to prevent overspray of the liquid coating composition onto the opposite glass surface.

Abstract: A method is disclosed for pyrolytically forming electroconductive tin oxide films having higher resistivity for a given thickness than tin oxide films formed by known methods by adding to the film forming solution an organic compound which retards the rate of film formation reducing the particle size of the tin oxide film thus increasing the resistivity of the film. Small quantities of an organic compound such as cresol or benzyl alcohol added to the film-forming solution may increase the resistivity by a factor of five for a typical film thickness.

Abstract: A tile wall cover for electrical outlet boxes includes a ringlike flat plate having a large central opening therethrough. A ringlike extension is secured to the plate around the opening. The extension is formed from a pair of substantially identical generally U-shaped members each having a base and opposite first and second legs. The first leg on each member has an offset terminal end portion which is offset toward the second leg a distance generally equal to the thickness of the material from which the member is made to form a rabbet on the outer surface of the first leg. The pair of members are reversely positioned with the rabbet on the first leg of each member receiving the terminal end portion of the second leg on the other member.
