Abstract: An implant device is configured to be implanted in a fistula to fluidly connect the lacrimal apparatus and a paranasal sinus. A surgical tool has an implant the implant device mounted on a carrier. Various methods involve a fistula between the lacrimal apparatus and a paranasal sinus. A kit includes an entry device for use to form a fistula and an implant tool for use to implant an implant device following formation of a fistula.

Abstract: An implant device to provide an artificial fluid path in fluid communication with the lacrimal apparatus is implanted through a fistula opening into the lacrimal apparatus using a working member disposed through the implant device and a break-away sheath. Implantation kits and tool assemblies including the working member, implant device and break-away sheath facilitate implantation of the implant device.

Abstract: A method of and apparatus for testing the performance of a tool for use in the humane slaughtering of animals wherein a bolt accommodated within and coaxially of a barrel of the tool is adapted to be driven lengthwise of the barrel by a force applied thereto. The method and apparatus includes mounting the tool on a test rig, firing the tool, detecting the time for the captive bolt to travel a pre-determined distance, applying a calibration factor to the detected time to compensate for time delays and determining the actual time to travel the pre-determined distance, and generating a signal representative of the condition of the device based on the actual time.

Abstract: Preferably the land levelling device (1) includes a support frame (2) on which is mounted a front, transversely extending, blade (3), a rear, transversely extending, blade (4), and a coupler (5) for, in use, attaching the land levelling device to a towing vehicle (30), the support frame (2) mounting the front and rear blades (3, 4) in substantially parallel spaced apart relationship wherein the front blade (3) has a cutting edge (9) projecting foremost, and a cutting face (10) angled backwardly and upwardly from the cutting edge (9) toward the support frame (2), and wherein the rear blade (4) has a lower edge (13) which lies below, or at least co-planar with, the cutting edge (9) of the front blade (3), the construction and arrangement of the front and rear blades (3, 4) being such that in use mounds or bumps in the ground are sheared off by the front blade (3) and pass over it to be redistributed into hollows in the ground by the rear blade (4).

Abstract: A glass sheet to be heated, for example to a bending or a quenching temperature, is supported on its lower edge in an upright disposition and is advanced along a horizontally disposed path through a furnace. Transient support is provided for the upper edge of the sheet which support is positioned to cause the sheet to lean at a near-vertical angle as it is advanced, and thermal conditions in the furnace as well as the time the sheet is within the furnace are set in dependence on the glass thickness so as to heat the glass to the required temperature while permitting the glass to relax as it is heated only by an amount less than a maximum acceptable deformation of the sheet which depends on the use to which the sheet is to be put.
