Abstract: A securing mechanism and method for a conventional door frame strike support structure, which substantially increases the holding strength of the strike and mounting assembly. The mechanism comprises two support members that are secured and concealed within the frame jamb structure behind the strike plate in a horizontal position parallel to the body of the strike plate, and with transverse interconnecting threaded means to adjustably secure the strike plate. The final assembly is ready to act with a high degree of mechanical resistance in direct opposition to any external force applied against the door. The strike support system is versatile, being adaptable to various existing designs of strike plates and deadbolt keeper plates and even for different levels of tensile strength.

Abstract: There is provided an improved combination oil and gas nozzle comprising a housing, a forward portion of which includes an enclosed chamber adjacent at least a part of a combustion zone, a gas inlet into said housing leading to a mixing chamber within said housing, an air inlet into said housing leading to said mixing chamber, a series of passages leading from said mixing chamber to a rearward portion of said combustion zone, an oil lance and nozzle extending through the rear portion of said housing and extending essentially centrally into said combustion zone downstream of the outlet of said series of passages, an oil inlet to said essentially annular chamber and an oil passage from said chamber to said oil nozzle. There is further provided a method of utilizing oil and gas in combination in such a nozzle.

Abstract: A machine for compacting in one series of operations up to a truckload of snow removed from city streets and the like. The machine has a hopper for receiving such snow, a compacting chamber and a hydraulically operated blade for compacting snow in the chamber. The compacting chamber is positioned below and to one side of the hopper whereby it is gravity fed. The chamber has opposite, parallel, fixed sides on all but the blade and exit sides. The exit side is completely closed in by a gate. Means are provided to move the blade from a first position below and to the outer side of the hopper to a second position towards the exit gate of the chamber when in compacting action, and from this second position back to first position when in recharge action. Further means are provided to pivot the blade from a transverse, fixed, vertically oriented position when in compacting action to a transverse, fixed, horizontally oriented position when in recharge action.

Abstract: A building structure employing an easily erected and dismantled frame with a stressed membrane cover wherein the framework comprises a plurality of transversely disposed arch-like members spaced longitudinally of the building with a strip of fabric stretched between each adjacent pair of arches, each of said frame members being of an extruded aluminum alloy I beam having a web with an exterior crosshead and an interior crosshead. The I beam's exterior crosshead has a fabric capturing device interacting therewith to secure the edge of the fabric strip against escape and provide a weatherproof joint between the fabric and the beam. Extendable spreader beams are mounted on the upper side of the interior crosshead, they and any appurtenances other than the fabric capturing device already mentioned connected to or slung from the arch frame beams being positioned below the fabric membrane where they are protected from the weather and readily accessible from within the structure.

Abstract: An adjustable strike for a latch bolt of a swinging door, the strike having a face plate to be placed over an appropriate cavity and having a lip to extend into the doorway to engage and to press the latch bolt as the door closes. A flange is secured normal to the plate to extend into or beside the cavity between the plate opening and the lip. A bolt extends through the flange, preferably being threaded therethrough. A movable wall, parallel to that flange and spaced therefrom is secured to the end of the bolt and situated within the cavity behind the face plate, to be positioned within the plate opening so that the keeper surface of the latch bolt will bear against this wall when the door is closed. Longitudinal movement of the bolt and the flange causes the wall to move towards or away from the flange, thereby altering the distance between the door stop and the movable wall. The wall is moved to a distance which will provide a secure fit of the latch bolt and minimize rattling of the closed door.
