Abstract: A bag-opening device having a first plate with a first perimeter extending therearound, a second plate connected to the first plate and having a second perimeter extending therearound, and a blade affixed to one of the first and second plates and positioned generally centrally therein. The first and second plates are movable between a first bag-receiving position and a second bag-opening position. The first and second plates have a V-shaped configuration in the first position and are in parallel relationship in the second position. The blade is positioned perpendicular to the plates in the second position. The first and second plates are integrally formed together of a memory-retentive polymeric material. The first plate has a first neck extending rearwardly therefrom. The second plate has a second neck extending rearwardly therefrom. These necks have a width less than a width of the first and second plates.

Abstract: Means and methods are provided for the in situ repair with liquid resin of shatterproof windshields and the like. An apparatus is provided which is composed of a plate disposed at the top portion of a preferably rectangular housing which supports a novel injector assembly and pressure assembly. The support plate is pivotally interconnected to the top portion of the housing preferably by a pair of hinges disposed on each of the housing's longitudinal sides. The housing is secured to the surface of the windshield by a vacuum created by the action of a membrane-handlebar assembly. The injector assembly is disposed perpendicularly of and axially through one of a plurality of ear-like apertures. The apparatus is adapted to enable convenient adjustments to the pitch and elevation of the injector assembly with respect to the surface damage, accordingly provide a means and method to maintain the requisite pressures upon the liquid resin as it is transported through the injector assembly to the seal-damage interface.

Abstract: A dental apparatus adapted for penetrating and cleaning the interstices and interproximal surfaces between the teeth, the surfaces at and below the gum margins, and the tooth-gum interfaces including the grooves and crevices thereof, is provided. In a preferred embodiment, a neck portion interconnects an elongated handle portion and a head portion, with the head portion being angled upwardly of the handle portion. A plurality of tufts of bristles are fixedly attached to the face of said head portion, said tufts of bristles having wedge means and conforming means to enable penetration into and cleaning of said interstices, surfaces and interfaces.A single row of a plurality of tufts of bristles, disposed substantially perpendicularly of said handle portion, has the free end of each of said plurality of tufts which are disposed at said end of said head portion beveled, said bevel sloping upwards from a vertex formed at said free end of the outermost bristle in each of said tufts.

Abstract: An electronic system and method are disclosed for controlling a measured temperature during a sequence of time intervals, in accordance with a sequence of selected reference temperatures, each corresponding to one of the intervals. The values of the reference temperatures are programmable and changeable by the user. The system and method can be used to establish thermostatic control in conformity with a referenced temperature that varies throughout the day, for example, hour by hour. The system also provides for using different sequences of reference temperatures on different days.

Abstract: Methods and means are provided for detachably interconnecting electrical components in an electrical system located and used in a disadvantageous environment. An improved connector device is provided which is composed of spaced-apart metallic terminals embedded in a substantially rectangular body member and adapted to be electrically joined with leads in a cable or the like. One pin-end portion of each terminal is located in a sidewall recess in the body member, and the other socket-like end portion of the terminal projects into and through a plug-like extension from the body member opposite the sidewall recess containing the pin-like end portion.
