Title: Vermin control using microwave energy
IPC: A01M1/22
Filed: 1993-03-17
Abstract: "Vermin control with the aid of microwave energy". The microwave wavelength will cause the vermin to die either by heating the bodily fluids or by heating the material surrounding them. The surrounding material often contains water, which will start to boil owing to the high dielectric losses. The frequency of the microwave energy is one of the frequencies permitted internationally for heating purposes. The term vermin refers to: animals noxious to man, both in material terms and from a health point of view. Examples of vermin are: insects and their larvae, small mammals etc. The vermin can be exposed to the microwave energy in various ways: 1: by placing the infested object into a space to which the microwave energy is supplied, in a manner similar to the normal microwave oven; 2: by irradiating the infested objects with the aid of an antenna to which the microwave energy is supplied. The antenna will be a directional antenna with a small angle of aperture, often a horn antenna (horn aerial) or a parabolic antenna. As high energy levels are used, the operating personnel require protective clothing which consists of a suit, which encloses the entire body, has metal incorporated therein, and offers sufficient protection even at very high field strengths. The advantages of the invention are: 1. no pollution; 2. can be used even in not readily accessible or inaccessible locations; 3. fairly rapid operation; 4. does not leave any traces; 5. does not use poisons hazardous to humans and animals; 6. convenient in operation. A drawback that must be mentioned is that protective clothing is required.

Title: Down-hole seismic prospecting method
Inventor: NAVILLE CHARLES
IPC: G01V1/46
Filed: 2002-04-04
Abstract: In a seismic prospecting method, tube waves are allowed to attenuate while propagating along a liq.-contg. well hence producing parasitic signals sensed by seismic receivers which are coupled with an underground formation, crossed by the well, in response to waves applied to the formation. The novelty is that a gas, which is insoluble in the liq. and which is sufficiently compressible to absorb at least part of the energy transported by the tube waves towards the seismic receivers, is dispersed within the liq. in the upper part of the well during seismic prospecting operations. Also claimed are devices for carrying out the above method.

Title: Unmanned diagnostic communications system for computer controlled machine tools
IPC: G05B23/02
Filed: 1981-11-06
Abstract: An unmanned diagnostic communications system for analyzing the operation of a remotely situated computer controlled machine tool and for diagnosing any abnormalities disclosed during machine tool operation includes an auto dialer and MODEM coupled between the computer controlled machine tool and one end of a communications channel and an auto answer MODEM coupled between the other end of the communications channel and a diagnostic computer. In response to a test command entered by an operator to the remotely situated computer controlled machine tool, the auto dialer automatically establishes a communications link with the diagnostic computer through the auto answer MODEM. Thereafter, the diagnostic computer determines the identity of the remotely situated computer controlled machine and then transmits instructions to the computer controlled machine tool to direct its operation. In accordance with the program instructions from the diagnostic computer, the computer controlled machine tool transmits data indicative of machine tool operating characteristics to the diagnosing computer which is then analyzed by such data to detect and diagnose any machine tool abnormalities.

Title: Control valve for vehicle hydraulic brakes - has pump outlet restriction valve which raises pump outlet pressure, applying brakes when required
IPC: F16K/
Filed: 1988-07-01
Abstract: The flow regulating valve has the inlet (2) of it's valve body (1) attached to the outlet of a continuously running engine driven pump (3). The piston valve slides within the body, it's position controlled by a diaphragm (15) to which it is connected (9) through a sealed (11) end (10). The position of the diaphragm is controlled by a spring (18) and atmospheric pressure on one side and a pressure (13) controlled by a driver operated brake lever (107) on the other. Decrease in the pressure (13) causes the valve (8) to move downwards, restricting the pump outlet and so pressurising the brake system through a parallel pump outlet.
