Title: Improvements in apparatus for filling extrusion gun cylinders with viscous substances
Inventor: BRADY ERIC
IPC: F16N37/02
Filed: 1982-06-08
Abstract: The apparatus comprises a base plate 2 on which a container 3 of viscous substance rests, a ladder like device 4 mounted at one end of the base plate, and a lever 8 with one end engaging a rung 7 on the ladder, the other end forming an operating handle and the central portion forming a ring 9 to engage over the closed end of a cylinder 10 of an extrusion gun, the cylinder being positioned over an aperture in a disc 16 lying on top of the contents of the container.

Title: Identification device
Inventor: OSBORNE DONALD
IPC: A01K11/00
Filed: 1984-10-24
Abstract: An electronic identification transmitting tag, Fig. 1a, for carrying by a human or animal or inanimate object, is presented at an identification station where interrogation apparatus 11, 12, Fig. 1, transmits energy which is collected to power the tag circuits. The frequency of the interrogate signal is divided to provide clock and carrier frequencies, the clock signals being applied to a ripple counter 41 having selected outputs connected to an output line so as to provide an identity data pulse train. The identity signal gates the carrier frequency signal to a transmitter 32. The signal transmitted is at a fundamental carrier frequency and at sub-harmonics of that frequency. A signal receiver 13 applies the harmonic rich signal received to phase lock loop detectors 52 tuned to the fundamental and various harmonics so that simultaneous detection of the same signal enables verification of the information transfer operation. One possible tag includes temperature sensing and temperature data transmitting capabilities, e.g. for animal body temperature monitoring. <IMAGE>
