Abstract: A toxic waste storage facility is formed of a plurality of contiguous storage cells. Each of the storage cells has walls made from compacted earth blocks and has a floor of compacted layers of clay with an impervious plastic liner beneath the layers of clay. A plurality of liquid storage containers, each containing toxic waste, are stacked in each of the storage cells. Clay filler is located within the walls of the storage cells and fills the space around the containers.

Abstract: A machine which makes building blocks from earth efficiently and rapidly has a pair of block forming molds at each end of the machine for simultaneously forming blocks at each end by means of a pair of rams. The hydraulic cylinder which actuates the two rams is located away from the axis between the two rams. The use of two molds eliminates wasted motion of the machine as a block is formed at one end of the machine as the ram is being retracted from the other end.

Abstract: An improved and simplified lock housing assembly for positioning and retaining lock or latch assemblies in cutouts in glass doors provided for that purpose which, outside of standard components such as screws, uses extrusion produced components so that the requirement for heavy machining and complex manual assembly is eliminated. The assembly includes a pair of spacers cut from the same extrusion which nest against an extruded elastomeric, channel shaped grommet about the cutout and position the lock assembly. The spacers are retained in the plane of the door by lengths of extruded plate which are fastened by screws to the opposite sides of the spacers and extend over upper and lower portions of the grommet. The screws and the grommet portion still exposed are in turn covered by extruded cover plates which include channels which slide over and dovetail with chamfered edges of the screw plates.

Abstract: A solenoid and electric terminal heads are embedded in plastic by injection molding. Die faces accurately position and orient contact surfaces on the heads relative to the solenoid and contacts on the solenoid plunger, eliminating subsequent machining. The solenoid windings and lead wires are encapsulated by plastic injected in the molding process through openings in the coil casing. Portions of the lead wires outside of the casing and contact posts connected thereto are also embedded in the plastic. Injection molded walls guide axial movement of a rectangular contact member with the plunger and prevent its rotation out of alignment with the terminal heads. A fibrous washer compresses axially under the die force to compensate for cumulative axial tolerances of the solenoid and terminal heads for accurately positioning the bottom of the plunger opening relative to the contact surfaces on the terminal heads.

Abstract: An insulating panel comprising a plurality of transparent plastic members, usually tubular and substantially rigid, positioned in parallel relation and extending over one surface of a glass sheet, and a transparent plastic cover sheet extending over at least the one surface of the glass sheet and the plastic members and secured to marginal areas of the glass sheet to form a unitary hollow insulating structure therefrom. Or two plastic cover sheets may secure tubular plastic members in the open center of an open center frame.

Abstract: A closure means for a syringe of the type wherein the nozzle or stem is intended to be transported separately from the syringe body. Double, continuous threads are provided on the nozzle or stem to be engaged by two pairs of oppositely positioned wedges in a connecting member which are positioned in a helical pattern to accommodate the threads of the nozzle or stem, with one of the pairs of wedges positioned at a different flight on the helix than the other pair and all of the wedges positioned 90.degree. from each other.
