The mixture provides improved propellant ignition and non-toxic ignition products, and minimizes misfires in that it contains no hygroscopic compounds.

Abstract: A conveyor system with a support apparatus for maintaining non-pendular substantially straight-line motion of the material-conveying member thereof, wherein the support apparatus includes straight-line linkage which is mounted between a rigid supporting surface and the material-conveying member so as to restrict movement of the material-conveying member to a substantially straight-line non-pendular path parallel with the path of conveyance. Each straight-line linkage assembly which supports the material-conveying member includes a set of three linkage arms which are pivotally interconnected with resilient bushings that continually urge the linkage to a central neutral or resting position during movement thereof. Two of the linkage arms are pivotally connected in spaced relation at one end to a rigid support, and are each pivotally connected at their opposite end to a third intermediate linkage arm which is disposed therebetween.

Abstract: A restructurable enclosure having a plurality of mounting blocks which are secured to the body of the enclosure at various spaced locations around and adjacent the outer peripheral portions of the door and wall panel openings therein. Each of the mounting blocks includes a plurality of threaded bores in the bottom surface thereof which communicate with openings in the enclosure body to facilitate permanent mounting of such blocks to the enclosure, and to facilitate attachment of sub-panels and other assemblies within the interior thereof, without obstructing the same. Each block also includes a pair of threaded or open bores extending inward from its outer mounting surface to facilitate mounting of the enclosure door or various wall panels to the enclosure solely from the exterior of the enclosure, without the need for accessing the interior thereof.

Abstract: A dual drive conveyor system which has a vibration control mechanism for adjusting the application of vibratory force to the material-conveying member without changing the direction of the resultant line of vibratory force generated thereby, wherein the vibration generator connected to the material-conveying member includes a pair of opposing parallel counter-rotating eccentrically weighted master shafts driven by a first drive motor, and a pair of opposing parallel counter-rotating eccentrically weighted slave shafts driven by a second drive motor, the master and slave shafts rotating in such manner that the direction of the resultant line of vibratory force is substantially only parallel with the longitudinal centroidal axis of the material-conveying member.

Abstract: A multifaceted modular enclosure frame which is constructed of a latticework of identical cross-sectionally configured frame sections that include an inherent integrally formed guide system for proper installation and positioning of sub-panel mounting boards within the enclosure. Each frame section defines an interiorly disposed guide channel and mounting flange, an exteriorly disposed corner flange, and an exteriorly disposed flange trough, while maintaining an open design and a cross-sectional configuration which mates cooperatively with other identically configured frame sections to provide an integral mitered corner which is devoid of separate corner adapter inserts. The interiorly disposed guide channel provides the integral guide system for the sub-panel mounting boards which are received within the enclosure. Each corner flange defined by such frame sections provides an exterior surface upon which mounting blocks are carried to provide for complete external connection of enclosure wall panels thereto.

Abstract: A stairway climbing aid having a plurality of individual adjustable half-step members fixedly connected to a rigid elongated channel member at spaced locations along the length of the latter to comprise a rigid assembly. The channel member is connected to each of the half-step members adjacent the rear end of the latter and at an elevation and angle such that the channel member will extend upon or adjacent the outer edge of the tread of each step. The half-step members are longitudinally adjustable so that their length can equal the depth of the particular steps to which they are applied. Thus, any stairway can be readily modified to facilitate travel thereover by persons having difficulty in taking full steps, by applying such an assembly to the steps along one side of the stairway, after adjusting the individual half-steps to the depth of the treads.

Abstract: A musical drum mount including a rigid but flexible band which is independent and disconnected from the drum, and which extends circumferentially therearound to support the drum from a conventional supporting structure. The rigid band carries a plurality of circumferentially adjustable insulating supports which extend radially inward from the band so as to engage the drum and support the same within the band without being physically connected thereto. Each of the moveable insulating supports have a drum bearing surface which insulates the drum from the grounding effect of the floor stand or other supporting structure therefor, and engages the drum to support the same above ground level. The circumferential movement of the insulating supports provides versatility of use with a variety of different conventional drum structures having various placement of head tightening lugs therearound. The rigid band is diametrically adjustable so as to accommodate a number of differently sized drums.

Abstract: A system for installing and properly positioning a sub-panel mounting board within a freestanding electrical enclosure, wherein the base sections of the enclosure frame form a continuous rectangular guide channel around the inner periphery of the enclosure which is designed to receive in opposite parallel channel segments thereof a pair of channel followers that are connected to opposite lower corners of the mounting board. Each channel follower has a depending leg which extends into its respective channel segment and supports the mounting board during installation thereof. The depending leg of each channel follower engages the bottom of the channel when the mounting board is tilted forward for installation within the enclosure. Once the mounting board is installed and positioned upright, each channel follower rests upon a mounting flange formed by the enclosure frame, thereby allowing the mounting board to be secured thereto.
