Title: Recovering clay pigeons using inclined collection nets - by adjusting nets to inclinations of bases of arriving pigeons
IPC: F41J11/00
Filed: 1974-11-06
Abstract: The system is for use with clay pigeons in the form of flat-based discs, and consists in stretching out one or more flat nets (36), but inclined to the ground at an angle which is a function of the speed of launching of the clay pigeons and the distance between each net and the launcher. Thus each clay pigeon arrives with its base parallel to the plane of the net, and slides a short way up it before halting on arrival, while sliding downwards under gravity when a fresh clay pigeon shakes the net. The net can be secured at the corners to posts at adjustable heights.

Title: Tubular plastic sachet with external ancillary reagent pocket - for self curing mastic packs for construction bolts etc
IPC: F16B13/14
Filed: 1975-07-25
Abstract: Sachet incorporating the active reagents of a self curing mixt. is packed by partially filling a flexible thermoplastic tube with the major precursor of the mixt. while externally creasing the tubing to form an external longitudinal pocket which can be loaded with the minor precursor reagent and sealed by an ancillary cover tube.
