Abstract: An ear tag for livestock identification, particularly suited for cattle. The tag, made of a resilient material, is mounted on the animal's ear using a clip. The tag has a mounting flap at nearly a right angle to the display face. The clip is inserted through the rectangle hole in the top of the display face. The clip, which may be a metal tag, is installed in it's standard manner. The buttonless tag hangs in front of the ear. The mounting flap ensures the tag hangs down at an angle which enables the display face to be read at a distance. The tag has an emergency tear section. In the event the tag permanently catches on something, the tag will tear off at the emergency tear section, leaving a small portion of the tag and the metal tag clip in the animal's ear. Both the metal tag and the portion of the tag remaining can also be numbered as a back-up identification.

Title: Quick-release spike for footwear
Inventor: SAVOIE ARMAND J
IPC: A43C15/02
Filed: 1997-01-10
Abstract: A removably attachable traction gear for the underside of footwear having two primary components: a retaining member and a receptacle. These two components respectively replace the common screw and threaded receptacle systems found in for affixing traction gear to the underside of shoes. A partial turn of the traction gear securely locks the gear into the receptacle. The retaining member has a three-extension design so as to make the traction gear resistant to lateral forces applied to the ground-engaging end of the cleat. Locking is achieved through use of cantilevered fingers which press in during installation of the retaining member, and which spring back out to lock with mated indentations in the extensions. During installation a dome containing insole material is compressed. Unlocking is achieved through reverse turning the retaining member to force the springs back in, and removal is aided through re-expansion of the dome. In a preferred form, the invention is utilized to attach a golf cleat to a shoe.

Abstract: An energy meter (2) comprises a combustible fuel gas inlet (48) and a fuel gas outlet (50) and a central tube (12) along which the gas flows in travelling from inlet to outlet. Ultra-sound transducers (52 and 54) and a control (56) comprising computer means form a system whereby the speed of ultra-sound signals travelling through the gas between the transducers can be measured and utilised in the control to calculate the volumetric amount of gas which has passed through the meter. The ultra-sound signals pass through apertures (33 and 38) in the walls (24, 26) of chambers (32, 34) containing the transducers.  Another ultra-sound transducer (66) in the chamber (32) and connected to the control (56) acts as an emitter and receiver of ultra-sound signals reflected by reflectors (68 and 70). These signals travel through the fuel gas in chamber (32) and their attenuation is observed and measured by the control when they are received by transducer (66). The measured attenuation is used by control (56) to derive the calorific value and/or Wobbe index of the gas, and the control uses the volumetric amount of gas and the calorific value and/or Wobbe index to derive the amount of energy provided by the supply of the gas.

Title: Method of and apparatus for nuclear quadrupole resonance testing a sample
Inventor: SMITH JOHN ALEC SYDNEY
IPC: A61B5/055
Filed: 1997-08-28
Abstract: A method of nuclear quadrupole resonance testing a sample is disclosed in which the excitation applied to the sample is arranged so that phase and amplitude information may be obtained from the response signal, and in which the signal is resolved into two components. Particularly if a parameter such as radio-frequency field strength varies with position, this may give an indication of the distribution of nuclei in the sample, preferably from the phase of the response signal.  Positional information can also be obtained by measuring from two or more reference points. This may be employed in imaging. The phase information may be employed to improve the signal to noise ratio obtainable in other methods where only amplitude information was previously available, for example in distinguishing genuine NQR response signals from spurious signals.
