Patent CA-1322516-C (CA)
Inventor: CLAPP CLARENCE P
IPC: F23D11/42
Filed: 1989-04-10
Granted: 1993-09-28
Abstract: ABSTRACT OF THE DISCLOSURE     The invention provides a combustion device such as a stove which may include a pressurized fuel mixture, such as an aerosol container containing alcohol and a propellant which may comprise a normally gaseous hydrocarbon, such as a liquified petroleum gas.  The propellant and air are fed to a combustion zone as a combustion mixture, which is combusted therein in a cold start period to pre-heat the liquid fuel and vaporize it.  When the liquid fuel is vapor-ized by the heat provided by combusting the propellant gas, combustion is continued by combusting the vaporized liquid, e.g., alcohol, fuel.  The pressurized fuel composition may comprise a major proportion of alcohol together with a minor proportion of the hydrocarbon propellant starter fuel.  The method therefore includes carrying out an initial, cold-start phase of combustion utilizing the propellant as fuel, and a subsequent stage of combustion utilizing the vaporized liquid fuel.  Propellant gas, if any, dissolved in or other-wise carried over with the liquid fuel may also be combusted during the subsequent stage of combustion.

Title: Cryogenic nitrogen generator with nitrogen expander
Inventor: AYRES CALVIN L
IPC: F25J3/04
Filed: 1989-06-13
Granted: 1991-05-07
Abstract: ABSTRACT The present invention is an improvement to a conventional, single column, cryogenic, nitrogen generator which is able to produce nitrogen at near atmospheric pressure. In the improvement, the product nitrogen from the rectifier column is expanded through an expansion turbine to produce refrigeration for the process. Expanding the nitrogen makes it possible for the main air compressor to operate at a much lower pressure and achieve a significant reduction in compression power as compared to conventional waste expander and air expander cycles.

Abstract: A child resistant dispensing closure comprising a first part having a base wall and a peripheral skirt adapted to be threaded onto a container.  The peripheral skirt includes interengaging portions that engage portions of the container to prevent removal from the container. The closure also includes a second part or lid connected to the first part by an integral hinge and having a base wall, peripheral skirt and a closing portion adapted to extend into a nozzle on the base wall of the first part when  the  second part  is moved  into overlying relationship to the first part.  Snap lugs on the second part engage bead segments on the first part to hold the second part in closed position.  The diameter of the skirt of the first part includes a radial flange that extends circumferentially about most of the periphery of the skirt. The flange is connected integrally to an outer radially deflectable wall panel.  The skirt of the second part is smaller than the diameter of the flange so that the flange projects radially beyond the lid skirt and the lid skirt cannot be raised readily. A shoulder projects axially from the flange to center the lid and support the skirt against radial deflection.  By pressing the deflectable wall panel radially inwardly the panel engages an axial rib on the skirt of the lid camming the skirt of the lid upwardly and exposing it so that it may be opened.

The surfactant maintains the oxidiser salt in a finely divided state and also ensures that the liquid hydrocarbon remains uniformly distributed throughout the explosive mass as a stable coating of droplets on the salt particles thereby enhancing the explosive sensitivity of the composition. The preferred fuel is diesel oil and preferred surfactants include sodium carboxymethyl cellulose, long chain aliphatic amines, polyacrylic acids, sulphonated nuclear aromatic compounds, sulphonated dyes, sulphonated polymers and long chain alcohol sulphonates and phosphonates.
