Publication number: 20170253356Abstract: Self-heating containers comprise a reaction chamber and a heating chamber. The heating chamber is sized to contain a substance to be heated. The reaction chamber contains reactants which, when contacted, exothermically react. The reaction chamber is divided into a first compartment and a second compartment with a barrier therebetween. The barrier comprises a first barrier portion and a second barrier portion. The first barrier portion is attached to a reaction chamber wall and has an opening sized to allow reactants to flow through from one compartment to the other. The second barrier portion is attached to the first barrier portion to close the opening. The barrier can be opened by moving an actuator into engagement with the second barrier portion to dislodge the second barrier portion from the first barrier portion and thereby open the barrier. In certain embodiments, the heating chamber can be a can with prepackaged comestible substance therein.Type: ApplicationFiled: March 21, 2017Publication date: September 7, 2017Inventors: John Ford, Douglas Lund

Publication number: 20160265886Abstract: A reloadable plastic ammunition casing is provided for firearm use. The plastic casing is preferably constructed from currently available polymeric materials using plastic injection molding techniques. In the preferred embodiment the casing includes a cylindrical body having a top portion and a bottom portion. The top portion having an open end for receiving a propellant and a top lip for retaining a projectile. The bottom portion has an internal casing floor that includes at least one concentric step down towards a centrally located primer pocket such that an installed primer is located in blast communication with the concentric steps on the casing floor. The concentric steps uniformly disburse, distribute, and deflect the heat and gas pressures within the casing when fired, thereby avoiding structural failure, allowing for multiple reloads of a casing constructed entirely out of plastic.Type: ApplicationFiled: March 16, 2015Publication date: September 15, 2016Inventors: Lonnie Aldrich, Wando Maupin, Douglas Lund

Patent number: 7267010Abstract: A single axis vibration test system includes a vibration force generator or “shaker” which can be used with a head expander, and separate pairs of hydrostatic self-aligning sliding bearings connecting two large reaction masses to the head expander. Preload forces are applied by separate preload pistons supported on a preload ring surrounding the shaker. Preload forces are transmitted by the preload ring to the sliding bearings to clamp the head expander directly to the reaction masses, which resists lateral and rotational motions during vertical axis testing. The reaction masses are supported on resilient supports carried on a sub-structure rigidly affixed to ground, for avoiding a rigid connection between the preload ring and ground which in turn avoids unwanted mechanical resonances within the operational frequency range of the system during use.Type: GrantFiled: June 17, 2005Date of Patent: September 11, 2007Assignee: Team CorporationInventor: Douglas A.

Publication number: 20070125362Abstract: Various embodiments of the present invention feature a self-heating or self-cooling container that is simple in design. The container includes an outer container body, an inner container body, a reactant vessel, a breakable barrier, and a breaking device. The outer container body defines a first chamber and includes a first reactant. The inner container body defines a second chamber. The inner container body is disposed within the first chamber and hold a substance to be heated or cooled. The reactant vessel is provided within the first chamber underneath the inner container body. The reactant vessel contains a second reactant capable of reacting with the first reactant to generate an exothermic or endothermic reaction. The breakable barrier covers the reactant vessel. The breaking device is disposed within the first chamber between the inner container body and the reactant vessel.Type: ApplicationFiled: November 14, 2006Publication date: June 7, 2007Applicant: Heat Wave Technologies LLCInventors: John Ford, Douglas Lund
