Title: Method to avoid fluid spillage when uncoupling sections of a drill string using a metal slug inserted into the drill string
Inventor: ASTLEFORD JOHN
IPC: E21B19/16
Filed: 1999-03-10
Abstract: A method of avoiding fluid spillage onto a rig floor when removing drill string sections comprises the steps: lowering a metal slug into a drill string containing drilling fluid, allowing the metal slug to descend into the string thus displacing drilling fluid from the top of the string, withdrawing the string at a rate no greater than the rate of descent of the slug and then removing sections of the string. The metal slug has a density greater than that of the drilling fluid and a mass sufficient to balance a positive head of fluid in the bore outside the drill string so that the fluid level remains below the level of the rig floor when the sections are removed. The metal slug has an elongate body 30 of a sealing, but sliding fit within the string and comprises flexible sealing rings or scrapers 31. Each of the scrapers 31 may include a bypass bore 32 within the body 30 with each bore 32 containing a non-return valve 33. Buoyancy may be provided by a hollow portion 34 and a latching mechanism 35 may be located at the upper most end of the body 30.

Title: Compressed gas cartridge for multiple discharge use
Inventor: LANE ROBERT J
IPC: F41B11/62
Filed: 1999-03-12
Abstract: A cartridge for storing and releasing compressed gas which comprises a regulator valve (29) arranged to control the flow of gas from a high pressure gas storage chamber (C1) to a gas discharge chamber (C3) via an intermediate chamber (C2) so that when the gas pressure in the discharge chamber (C3) reaches a predetermined value the valve (29) shuts off the flow and when the gas pressure in the discharge chamber falls the valve opens to allow gas to flow into the discharge chamber, whereby the gas discharged from the cartridge in successive discharges is maintained at a substantially constant pressure despite the falling pressure in the storage chamber as the cartridge empties. The valve (29) comprises a piston (30) which forms a passageway (33) between the intermediate chamber and the discharge chamber and is movable into and out of contact with a seal which closes the passageway, the seal being adjustable to vary the pressure in the discharge chamber at which the valve (29) shuts off the flow of gas from the storage chamber (C1) into the discharge chamber (C2).

Title: Measuring usage of cellular mobile telephones
Inventor: LIM CHUEN KHENG
IPC: H04W16/18
Filed: 1997-01-28
Abstract: The mobile phone usage within a specific area is measured so as to identify a potential hotspot for installing a microcellular transmitter. This hotspot measurement is applicable to digital cellular communication systems utilising time division multiple access (TDMA) technology. The hotspot measurements are performed in real time, and the signals transmitted by all mobile phones within a specific area are received by a spectrum analyser. The spectrum analyser is set to zero frequency span, so that the signals are captured in the time domain. The analysis of data is performed after the data collection so as not to reduce the speed of the data collection process. This method provides a more realistic measurement as only the mobile phone users that are utilising the system are considered. By varying the threshold level, the number of mobile phone users within areas of different sizes can be determined.

Title: Chemiluminescent illuminating element
Inventor: GIGLIA ROBERT D
IPC: G01N21/03
Filed: 1992-09-11
Abstract: The invention relates to a chemiluminescent device, which comprises a tube made of a flexible, light-transmitting and chemically stable material, closed at both of its ends, and which comprises at least two compartments which are filled with liquids which produce chemiluminescent light when mixed. The tube contains, between the ends, an internal diaphragm or disk, which separates the tube into said compartments. The diaphragm or disk has approximately a flat circular shape, with a cross-section which is approximately rectangular in profile, and is placed transversely with respect to the axis of the tube. The edge is in continuous contact with the interior of the wall of the tube. The elasticity, the external diameters and the internal diameters of the tube and, the diameter and the thickness of the diaphragm are selected in such a manner that the diaphragm can be tilted by simple manual pressure against the external walls of the tube, which pressure imparts a tilting torque to said diaphragm or disk and allows mixing of the contents of the compartments. The closure at both ends is a fusion of the side walls of the tube and each comprises an area lying in a substantially flat plane. The tube has a Stiffness Modulus of less than about 700 mPa and a Tensile Strength greater than about 15 mPa.

Abstract: An improved locking mechanism for detachably securing a seat back (18) to a chair frame is disclosed. The improved locking mechanism includes a pair of slide brackets (54) secured to opposite sides of the seat back (18). Linkages (20) supported from the chair frame are provided for receiving the slide brackets (54) thereon for supporting the seat back (18) on the chair frame in a predetermined orientation relative to the seat member. A moveable locking arm (72) is supported from the slide brackets (54) and includes an offset arcuate cam surface (75) which is adapted to engage an arcuate notch (76) formed on the linkage (20) when the locking arm (72) is moved to a locked position.

Title: Electric welding
Inventor: KORENAGA MICHITAKA
IPC: B23K9/073
Filed: 1978-02-01
Abstract: PURPOSE: About equally spaced negative terminals surround a welding portion which is made the center positive terminal. So arranged electric circuit causes no stary current.  
     CONSTITUTION: A welding portion of material to be welded is made a positive terminal. Two or more of negative terminals are installed at about equal space around the positive terminal as the center. This forms an elctric circuit for the material to be welded, circulating between the positive and negative terminals. When a small diameter pipe is welded, it is preferred that about equally spaced bands are used as negative terminals to be placed at two locations around the pipe as the center. When a curved or flat portion of plate material is to be welded, about equally spaced plural negative terminals are preferably installed on the curved or flat surface with the welding portion as the center. In some case, magnetic material can be advantageously used as the negative terminal to be attached to the welding material. Preferably, electric welder grounding should be disconnected when welding.

Title: Printer device provided with bar-code read function
Inventor: MIYAMOTO SATOSHI
IPC: G06K7/10
Filed: 1990-01-19
Abstract: PURPOSE:To stably read a low density bar-code, as well by using a high density mark sensor by setting a distance between the sensor and the bar-code to what is called an out-of-focus position shifted from an optimal position by an automatic paper thickness adjusting mechanism at the time of reading the low density bar-code. CONSTITUTION:At the time of reading a high density bar-code, a distance between a sensor 2 and a bar-code (paper surface) is set to an optimal position in which a high resolution characteristic of the sensor 2 can be displayed enough. On the other hand, at the time of reading a low density bar-code, the distance between the sensor 2 and the bar-code is set to what is called an out-of- focus position shifted from the optimal position by an automatic paper thickness adjusting mechanism 20. In such a way, the device comes to scarcely respond to minute dust or contamination, and a defect at the time of reading a low density bar-code by a high resolution sensor is obviated.
