Abstract: A Door Locking/Securing Device comprised of Two Separate Machined Steel pieces including a Bracket and a Removable Insert. The Bracket which Fits in the Clearance between the edge of the Door and Door Jamb is Secured to the Door Jamb so that projections extend into the Room into which the Door opens. The removable insert fits onto the projection of the Bracket when the door is closed preventing the Door from being opened. This forms a highly effective barrier preventing the forced opening of the Door from the exterior.

Abstract: A portable water heater unit is used to warm a source of ambient temperature water for field use. Warm or hot water is provided for food warming, making hot beverages, showering, and article washing purposes. The unit comprises a housing, a water heater mounted within the housing, a hot water holding tank mounted within the housing, an optional heat exchanger positioned in the hot water holding tank and a temperature control mixing valve operably associated with ambient and hot water lines. An ambient water inlet line leads from an external source of ambient temperature water to the water heater. A hot water line leads from the water heater to the holding tank. Water within the holding tank is directed to an external use source or is continuously recirculated back through the water heater and to the holding tank. An inlet line and an outlet line connected to the heat exchanger within the holding tank is used to supply hot water to make coffee, tea, soup or similar hot drink/food products.

The strip of complementary hook-and-loop material is removably affixed to one of the plurality of hook-and-loop material sections. The tee is a rubberized tee mounted at a point of pivotal connection of the first strip with the second strip. Each of the first and second strips are linear members having a tapered end opposite the block.
