Abstract: Testing procedures for milking animals whereby a milk flow has a sample flow diverted therefrom which is then tested for somatic cell count indicative of mastitis. Such testing of the diverted flow is automatic and involves a measure of viscosity change in the sample after the addition of an anionic detergent which causes gelling to an extent determined by the somatic cell count. As a consequence calibratable data from each milking animal can be generated and used as a comparative tool between animals and/or to monitor changes in the somatic cell count (SCC) of individual animals between milkings.

Title: Vital "and" gate apparatus and method
Inventor: EGNOT JAMES R
IPC: H03K19/007
Filed: 2000-12-29
Granted: 2009-05-19
Abstract: A method for performing an "AND" operation on two independent inputs (16, 18) in a fail-safe manner includes cascading two charge pumps (CP1, CP2) to output a condition signal representing the "AND'ed" state of the inputs. Each independent input has an active state asserted by a waveform of predetermined frequency and duty cycle, and an inactive fail-safe state asserted by a zero voltage. The method includes supplying power to a first charge pump, (CP1) supplying power from the first charge pump (CP1) to a second charge pump, (CP2) and supplying each of the independent inputs to one of the respective charge pumps. A condition signal is output using an output from the second charge pump. (CP2) Additionally, the method verifies the correctness of the frequency and duty cycle of each independent input (16, 18) using a cross connection scheme. This method provides a high-power, low-loss, and low-cost electrical circuit for operating devices responding to specific voltages, for example, vital relays.

Title: A method and an apparatus for producing a gaseous medium
Inventor: HALLSTADIUS HANS
IPC: B65B55/10
Filed: 2001-04-20
Granted: 2012-06-26
Abstract: The invention relates to a method and a system for producing a gaseous medium containing a sterilisation agent and for monitoring and regulating the concentration and quality of the gaseous medium. The method preferably includes concentration determination of a substance or agent in a sample of the gaseous medium in the presence of disruptive matter by means of light absorption, as well as an apparatus therefor. By measuring the light absorbency at two different wavelengths, it is possible to detect and compensate for the effect of disruptive matter such as dust particles, dirt and bubbles (aerosols). By also measuring the intensity of light emitted from the light source which has not yet passed through the measurement sample, simultaneously with the measurements of the absorbency of light allowed through the sample, at each measured wavelength, the actual concentration can be determined with improved accuracy. The method and the system are applied for the sterilisation of packaging materials, packaging containers and packing or filling machines within the food packing industry.

Patent CA-2426549-C (CA)
Inventor: KYRSTEIN JOHN P
IPC: B27B31/04
Filed: 2003-04-23
Granted: 2011-01-04
Abstract: This application relates to a self-contained apparatus for mechanically turning individual workpieces travelling on a conveyor, such as lengths of lumber travelling into or exiting from a sawmill. The invention reduces the need for lumber graders to turn lumber manually and thereby helps avoid repetitive motion injuries. The apparatus includes an adjustable height frame which is positionable alongside the conveyor. The frame supports a workpiece holder defining an open-ended slot for temporarily receiving an end portion of a workpiece. When the end of a lumber board or other workpiece is received within the holder, a proximity sensor causes the holder to rotate, thereby turning the workpiece lengthwise 180 degrees. The workpiece is then deposited on to the conveyor in its inverted orientation for further travel thereon. The apparatus may also optionally permit workpieces to pass through the holder when a "skip" rather than an "invert" signal is received. The workpiece holder may be connected to a rotatable shaft driven by an electric or hydraulic motor.

Title: Resistance welding electrode
Inventor: D ANDREA ANTONIO
IPC: B23K11/30
Filed: 2003-06-12
Granted: 2011-01-04
Abstract: A welding electrode for welding a fastener to an object is provided. The electrode includes a housing assembly with a bore disposed in the housing assembly. A pin is disposed within the bore and is movable along an axis between extended and depressed positions. The pin is retained in the bore by a flange on a lower portion of the pin that extends radially outwardly. A spring is arranged within the bore and urges the pin from the depressed position to the extended position in which a weld nut may be loaded onto the pin. The spring has a compressed length indicative of a spring failure. A stop such as a spring insulator is arranged within the bore adjacent to at least a portion of the spring. The stop extends generally longitudinally in the direction of the pin axis. The stop defines a maximum spring compression length in a fully depressed pin position that may be caused from an improperly loaded weld nut. The maximum spring compression length is greater than the compressed length so that the spring does not become compressed to the point of failure. The stop is preferably constructed from nylon and has a length sufficient to accommodate excessive forces on the stop caused by an improperly loaded weld nut.

Title: Estimation of localised corrosion penetration
Inventor: EDEN DAVID ANTHONY
IPC: G01N17/02
Filed: 2002-03-08
Granted: 2009-04-28
Abstract: The present invention provides a method and apparatus for estimation of general and localised corrosion penetration rates of metallic materials and objects. The invention can also be used to discriminate between general and localised corrosion. A one, two or three electrode probe having electrodes (101, 102, 103) made of the same material as the material being monitored is located in the same corrosive environment as the material being monitored. An electrochemical harmonic analysis is performed and electrochemical noise signals are monitored, and the resulting responses are analysed and compared to discriminate between general and localised corrosion attack and to determine a localised corrosion penetration rate. A law frequency sine wave is applied to the working electrode. Harmonic analysis of the electrode response provides information regarding the general corrosion rate and the stern-geary constant. Electrochemical noise analysis of the electrode response and comparison with harmonic data provides a means of determination of localised corrosion penetration rate.
