Abstract: An apparatus for grinding coffee beans having a hopper arranged to receive and dispense coffee beans. The coffee grinder also includes a conical burr arranged to grind the coffee beans dispensed by the hopper. The apparatus may be employed to grind roasted coffee beans for use in a coffee extraction (conventional coffee machines), for example in a cafe.

Abstract: This disclosure relates to an apparatus for grinding coffee beans. In one form, the apparatus comprises a hopper arranged to receive and dispense coffee beans.

Abstract: A wheelchair includes a frame and first and second rear wheels that are each independently mounted to the frame via a respective mounting hub. Each rear wheel is detachably mounted to its respective mounting hub at two or more distinct hub mounting points. Either or both of the hub mounting points can be movable with respect to a remainder of the hub. A disk can be positioned at the rear wheel and a stop element located at the mounting hub can be selectively operated to interfere with the disk to prevent rotation of that rear wheel. Each rear wheel may include a push-rim having an elastomeric outer layer to facilitate manual gripping and an externally facing generally flat side face. The frame can include first and second spaced apart and unitary tubes which each extend in an unbroken manner from a wheelchair seat to a wheelchair forward region.
