Abstract: An automatic clip or carrier 100 fed pellet implanting gun apparatus 10 is described. The gun uses a pivotable lever 15 with a projection 15e on arm 15b which engages an arcuate surface 101a of a cam 101 on the carrier and snaps into place adjacent a drive surface 101b of the cam when the trigger 36 is depressed and then the projection engages the drive surface to move a next adjacent a new chamber 100a into line with a barrel 13a of needle 13 and opening 14k in a head means so that rod 31 can again insert a pellet. The gun apparatus is particularly adapted to implant pellets in animals, particularly as medicament pellets.

Abstract: An electroejaculation device has a hollow insulating housing with a set of longitudinally extending electrodes projecting from its outer surface. The housing encloses an electronic circuit that applies a sinusoidal output signal of alternating stimulation and rest periods to the electrodes. The circuit automatically increases the signal strength during successive stimulation periods through the cycle and varies the frequency of the signal during at least part of each stimulation period. An electrical plug sealed in one end of the housing connects the circuit to an external power source and preferably includes by-pass connections that allow the circuit to apply its output signal to the electrodes of a second probe that does not include a self-contained signal generating circuit.
