Abstract: A pedal cartridge for an aircraft. The pedal cartridge is connectable to a pedal mechanism and includes: a pedal. The pedal includes a pedal axle receiving portion configured to receive a pedal axle of the pedal mechanism such that the pedal is rotatably connectable to the pedal axle. The mechanism also includes a first rotation sensor component, the first rotation sensor component configured to interact with a second rotation sensor component of the pedal mechanism to permit rotation of the pedal about the pedal axle to be detected.

Abstract: The present invention provides a drilling tower having a rod handling tower allowing for the retrieval of rods from a rod rack system in an automated manner. The present invention also provides a method to deliver and install a core drilling platform in a remote area and its removal by air. The present invention also provides a cold box assembly for the storage of core drilling samples.

Abstract: A reusable contents expeller for collapsible tube which prevents contents from reverting back into the collapsible tube and that can easily be removed and installed on another tube without the need to firstly insert it through the base of the collapsible tube. The expeller is comprised of an oblong element with two extremities, which is comprised of a place where it is thin at its thickness and across its breadth so that it is flexibly pliable to allow the oblong element to fold upon itself to the point where the two extremities join, thus forming two pressure plates. The pressure plates are further held and secured together by the use of a hinged flap contiguous and part of one of the pressure plates. The flap acts like a hook to secure both pressure plates tightly together. Once closed about a collapsible tube, the contents expeller for collapsible tube expels the contents when it is slid across the length of the tube.

Abstract: A locking mechanism for locking a movable member to a stationary member such as a movable door to a stationary door frame which comprises a member fixed to the door frame and having a projecting rim which cooperates with a U-shaped longitudinal section having a portion for connection to the movable door. The U-shaped longitudinal section receives the projecting rim. The U-shaped longitudinal section is adapted to receive one or more bolts which pass through the walls of the longitudinal section and are adapted to engage within slots or recesses in the projecting rim. At least one slidingly mounted rod is provided to carry the bolts which pass through the slots or recesses in the walls of the U-shaped section and engage the tongue shaped notches for locking the projecting rim with the U-shaped section. Additionally, two vertically adjustable bolts are connected with the sliding rod and these are adapted to engage the threshold and lintel of the door frame.

Abstract: A screw extruder comprises a casing connected to a bed, the casing comprising two portions connected together longitudinally by connecting elements. At least one of the casing portions is articulated with respect to the bed, and the connecting elements are adapted to release the connection between the casing portions at a predetermined casing pressure to allow the casing portion to articulate to thereby open the casing.

Abstract: A composite propellant comprises, by weight:A. from 78 to 92% of an oxidizing agent which is at least one of alkali metal, alkaline earth metal and ammonium chlorates and perchlorates,B. from 7.9 to 17.2% of an organic binder which contains oxygen but not nitrogen, andC. from 0.1 to 0.8% of a carbon-containing combustion regulator.This composite propellant is useful as a gas generator for inflatable cushion protection devices because the gaseous combustion products are substantially free from toxic gases.
