Patent CA-2151167-A1 (CA)
Title: Container with plug-in closure unit
Inventor: TRAGARDH PAUL
IPC: B65D5/72
Filed: 1995-06-07
Abstract: The invention relates to improvements regarding a combination of a container with a potential opening and a closure unit consisting of a pouring part (2) and a closure part (1) connected by a hinge (11), the closure unit being insertable into the potential opening of the container. By shaping inner retaining (22, 26) means according to the function of the closure unit, the force necessary for inserting the closure unit is minimized. The inner retainingmeans are formed preferably as a snap (22) in a position corresponding to the position of the hinge (11) and a retaining lip (26) in a position opposite the hinge position. The retaining lip (26) is slid sideways into the opening and then the snap (22) is pressed into the opening. As the retaining lip (26) does not need a sliding face (23) as the snap (22) does, the closure unit reaches less far into the container in the position opposite the hinge position than in the hinge position, such that without increasing its expansion perpendicular to the container wall the closure unit can be equipped with a pouring lip (27) opposite the hinge.

Title: Injection system for hybrid rockets
Inventor: STINNESBECK THOMAS L
IPC: F02K9/72
Filed: 1995-06-21
Abstract: The invention describes a hybrid rocket injection system designed to increase combustion efficiency and fuel regression of large and powerful motors of the internal burning type, whereby said injection system consists of a multitude of fine tubes originating at the periphery of the motor case and running radially through the solid fuel block towards a centrally located port, the effect being a thorough mixing of oxidizer and gasified fuel independent of port length. Oxidizer flow per fuel surface area can be kept constant throughout operation. By creating multiple sites with direct contact of oxidizer and fuel, fuel regression is no longer dependent on the fuel's previous gasification. The more feed tubes are provided, the better the invention will work. Their number, arrangement and layout allows to constructively predetermine the burn characteristic of the fuel block.   Said feed tubes or subsets are advantageously supplied through ducts running along the inside or outside of the motor case, whereby oxidizer flow to given subsets of feed tubes as multiple dependents of a common supply pipe can be controlled by regulating the flow into these pipes.
