Abstract: A modular building unit for construction of a building comprises a structural frame 40 suitable for interconnection to another modular building unit in construction of the building; and a stud frame wall 80/82 internal to and fixed to the frame. The modular building unit is suitable for handling as a shipping container for transport.

Abstract: An integrated propulsion system for hybrid rockets includes an oxidizer tank, a rocket engine, a pressurization device, a pressurization device and an oxidizer pipe and valve unit. The rocket engine is disposed within the oxidizer tank partially and located on a first side of the oxidizer tank. The pressurization device is disposed, at least in part, within the oxidizer tank, is located on a second side of the oxidizer tank opposite to the first side of the oxidizer tank, and is configured to regulate an overall pressure level within the oxidizer tank. The oxidizer pipe and valve unit is connected to the oxidizer tank and the rocket engine, and is configured to control feeding of an oxidizer from the oxidizer tank into the rocket engine.

Abstract: A booster system for a launch vehicle includes a plurality of core boosters and a plurality of patchy boosters. The plurality of core boosters and the plurality of patchy boosters are arranged in an inner space of a rocket casing of the launch vehicle, and the plurality of patchy boosters is separatable from the launch vehicle.

Abstract: The present invention relates to an assembly for storing bicycles, the assembly including: at least one fixed rail; and a support frame on which at least one bicycle can be loaded in an elevated position above the ground, wherein the support frame is moveable on the rail between a forward advance position for loaded and unloading the bicycle from the support frame, and a rearward retracted position for storing the bicycle. When the support frame is in the forward advanced position, a bicycle loaded onto the support frame can be locked to the support frame using a conventional bicycle lock.

Abstract: A composition for producing a sheet material with a cellular structure, the composition including the following components: (a) about 5 to about 25 weight % gelatine, (b) about 25 to 60 weight % filler material, (c) about 15 to about 40 weight % water, and (d) a cellular structure promoting agent.

Abstract: An assembly for storing bicycles in an upright orientation and suitably with both wheels of the bicycles off the ground. The assembly is configured to suspend the bicycles from their front wheel by engaging the front tire of the bicycles, and without needing to engage the rim of the front wheel, or the frame of the bicycle. Moreover, the assembly is adapted to allow the bicycles located in the upright orientation to be moved while on the assembly from side-to-side to allow bicycles storage to be clustered together and a bicycle to be retrieve-from storage to be spaced further apart from adjacent bicycles.

Abstract: A sheet material with a cellular structure wherein the sheet material is produced by preparing a composition including PVC, a filler material and a plasticiser and providing a cellular structure within the composition prior to curing to form the sheet material. The composition may further include a cellular structure promoting agent. The sheet material with a cellular structure may be used in building applications and has advantageous sound attenuation, thermal conductivity, resilience and impact resistance properties.
