Abstract: The amount of soot and slag formed during the combustion of carbonaceous waste material is appreciably reduced by combusting said waste material in the presence of at least 0.0001%, by weight, of sodium bentonite, based on the weight of carbonaceous material being combusted. The sodium bentonite may be added directly to the waste material before entering the furnace or the sodium bentonite may be added directly to the furnace.

Abstract: An alarm system for vehicles or the like responsive to unauthorized tampering. The circuitry includes at least two sensor arrays, each adapted to produce a signal responsive to tampering of a particular kind. In the case of an automobile, one sensor array is responsive to the opening of the trunk or hood, and its signal immediately actuates an alarm, such as sounding the horn; another sensor array, responsive to movement of the vehicle or opening of a door, produces a signal which, after a time delay of, say, 15 seconds, actuates the alarm. Another time delay circuit turns off the alarm after, say, 25 seconds. The circuitry includes arming means incorporating a third time delay, by which to arm the system after a delay of, say, one minute following the turning off of the ignition switch.

Abstract: This invention relates to a method for making brick from shale or a mixture of clay and shale by adding to the shale or shale mixture an additive containing sodium bentonite, a water soluble anionic polyelectrolyte polymer, and, preferably, a water soluble dispersant. The additive increases the plasticity and the green strength of the shale or shale mixture so that high quality bricks can be produced from such raw material.

Abstract: A balanced lid type system for industrial trash bins includes arrangements for partially opening the lid with little effort and for permitting the lid to swing wide open when it is inverted for dumping, as disclosed in U.S. Pat. Nos. 3,994,415 and Re. 29,494. The operative mechanism in the present balanced lid bin system includes rollers which ride on the top edge of the sides of the bin to support the lid in a substantially balanced manner, and a pair of recesses or guideways in the rear sides of the lid which engage matching pins or rollers extending laterally from the bin to guide the lid as it rotates open in the upright or balanced partially opening mode of operation. When the lid swings wide open, as it is inverted when raised by the forks of a lift garbage dump truck, the rollers remain at the end of the tracks in the lid and the lid swings fully open about this axis.

Abstract: An apparatus is disclosed for exothermically obtaining hydrogen or hydrogen peroxide from water vapor in a reaction chamber. The separation of the hydrogen and oxygen may be accelerated through the use of a combination host and sensitizer material which is present near spaces or voids within the reaction chamber. The water vapor has certain particular absorption bands in its absorption versus frequency characteristic. Each of the sensitizers which are located adjacent the voids in the reactant, in one embodiment forming part of the walls of small cylindrical tubes, has an energy output in the excited state which is precisely in one of the energy absorption bands in the water vapor characteristic. The host material absorbs heat energy and excites the sensitizer material. In addition to the formation of free hydrogen, some hydrogen peroxide is also formed. Other feedstocks may have energy selectively applied to them.

Abstract: A dual sensitive retractor prevents protraction of webbing when either a predetermined vehicle acceleration or webbing acceleration occurs. The reel includes a shaft which is rotatably mounted on a frame. Locking means, in the form of a lock cup, on the frame moves locking pawls into and out of the path of ratchet teeth on the reel. An inertia mass is mounted on the shaft for rotation with respect to the shaft, and an inertia weight is provided which is responsive to changes in the inertia of the vehicle. The invention includes the improvement of providing a latch and means for mounting the latch for engaging the locking means to prevent webbing protraction. Drive means, which in one embodiment is a cam fixed to the shaft contacting the latch generally is driven by the shaft and is connected to the latch to impart rotation from the shaft to the inertia mass and to move the latch into engagement with the locking means when the webbing acceleration rotates the shaft faster than the inertia mass.

Abstract: A device for opening, closing and latching a roof vent closure member for vehicles and including an upper latch member pivotally connected to the closure member, a lower latch member pivotally connected to the frame defining the opening in the roof, said upper and lower latch members being pivotally interconnected and a bar connected to said upper latch member in offset relation to its pivotal connection to the lower latch member for actuating the device. The pivotal connections of the latch members are arranged to provide a toggle or off center relationship in closed position of the closure member. The latch members and pivotal connections thereof are so arranged to permit the crossbar to be positioned below and outwardly of the frame defining the roof opening to provide headroom, non-obstructed vision, and aesthetic appearance.
