Title: Mechanical and gate for interlocking electric power switches and distribution system incorporating same
Inventor: JONES WILLIAM JOHN
IPC: H01H9/24
Filed: 2001-11-01
Granted: 2010-09-14
Abstract: A mechanical AND gate has a pivot plate with an elongated slot engaged by an output coupling formed by a pair of pins radially offset from the end of an output shaft. A pair of input couplings secured to the pivot plate at points laterally offset on opposite sides of the elongated slot couple first and second elongated actuators to the pivot plate. Movement of only one of the elongated actuators to an ON position causes the pivot plate to translate relative to the output coupling, but not to rotate. However, when the second actuator is moved to an ON position in a direction parallel but opposite to the movement of the first actuator, the pivot plate rotates to rotate the output coupling, and therefore, the output shaft. This mechanical AND gate has particular application to interlocking three electric power switches such as circuit breakers so that any two, but not all three, circuit breakers may be on at one time.

Granted: 2006-07-04
Abstract: It comprises a tube or catheter (1) that is introduced into the animal's vagina up to the cervix duct (19); characterized in that it additionally comprises a flexible probe (6) constituted of a first flexible tubular body (12), and the outside of which is covered by a layer of a flexible material; all to allow that the probe, after reaching the distal end of the tube (1), may progress through the cervix duct (19) and thereafter through the cervix horn (22). This structure allows to introduce a fluid with spermatozoids, embryos or therapeutic solutions to the anterior third of the uterus horn, or to obtain embryos from the anterior portions of the uterus horn, and all this without sedation or anesthesia and without disturbing the animal's well-being.      To facilitate obtaining embryos, the probe includes an elastic small external coating (28) that is inflated through a flexible tube (27) for adapting itself to the uterus horn (22) preventing refluxes when carrying out absorption.      It is essentially applied to porcine livestock, small ruminants and any other animal species.

Title: Waste water treatment system
Inventor: WILSON JAMES H
IPC: C02F1/42
Filed: 2000-10-27
Granted: 2008-03-25
Abstract: A method and apparatus for processing waste streams wherein a slipstream is formed on the upstream side of an ultrafiltration membrane (120) to carry collected and concentrated filter reject to a microfilter (170) via a conduit (155) at low flux through the microfilter (170). The low flux allows the particles to form an irregular matrix that itself helps to trap particles. The effluent from this matrix and microfilter (170) is returned upstream of the ultrafiltration membrane (120) to be repeatedly collected and concentrated. The suspended solids removed from the reject stream and microfilter (170) are then disposed of without further processing. To improve metal ion removal efficiency, sulfide compounds, etc.  can be injected upstream of ultrafiltration membrane (120). A combination of ozone and water can be used to backflush or to clean the ultrafiltration membrane (120). The backflushing water can be filtrate from the ultrafiltration membrane (120).

Abstract: The present invention involves a elongated member, such as a wire guide, that is used with in a endoscopic procedure. In one aspect of the invention, the elongate member includes a first system of indicia comprising a scale reference markings that can include numeric indicia, sequentially increasing markers, etc., located at regular increments (e.g., 1 cm) on the distal portion of the elongate member, that permit measurement of structures within a body passage. In one example, an exchange wire guide having a radiopaque marker on the distal portion is positioned under fluoroscopy at a first location, such as the distal point of a structure, and the scale reference marking on the wire guide that visible in the viewing region of the endoscope is read. The wire guide is partially withdrawn such that the marker corresponds to a second position (e.g., the proximal point of the stricture) and the new scale reference marking is read. The difference is calculated to determine the length of the structure. In a second aspect of the invention, a second system of indicia are included to aid the endoscopist in maintaining the device in position. These indicia, which may include oblique markings, helical striping, or some other closely spaced markings or pattern, help in the detection of longitudinal movement of the device.
