Abstract: A reference jig comprises a base adapted to be secured to a distal end of a bone. An adjustment mechanism has a bracket, one or more rotational joints operatively mounting the bracket to the base, whereby the bracket is rotatable in two or more rotational degrees of freedom relative to the base, and one or more translational joints. A landmark alignment unit is operatively connectable to the bracket by the at least one translational joint, the landmark alignment unit having a bone alignment component configured to be aligned with at least one bone landmark.

Abstract: An apparatus for the separation of a solid/liquid suspension by filtration includes a tank filled with a suspension to be treated. At least one cavitied plate is located in the tank and has at least one internal cavity. The plate is immersed in the suspension to be treated. The plate is inclined with respect to the vertical and only a lower inclined face of the plate is covered with a filter medium, the upper face being solid. The compartment of the cavitied plate communicates with a conduit which collects filtered suspension. Gas flushing pipes are positioned below the plate for emitting gas bubbles that pass across the filter medium and remove material clinging thereto.

Abstract: A self-contained device for self-service delivery of electrical energy, comprising a plurality of terminals, each capable of being connected to an electrical appliance, and a central management unit, operable independently of the terminals. The central management unit serves to: (1) manage distribution of electricity from an electrical supply grid to each of the terminals, (2) manage interaction between a prepayment instrument and users of the terminals, and (3) manage connection of the terminals to the electrical supply grid for transmission of electricity therebetween for either a period of time or a quality of electricity, as determined in response to a signal from the prepayment instrument indicating prepayment by a user.
